To keep an acceptable bending stiffness, some holes are created in the viscoelastic layer, thus facilitating the resin through layer penetration during the co-curing manufacturing process. Plates including (or not) one perforated (or non-perforated) viscoelastic layer are manufactured and investigated experimentally and numerically. First, static and dynamic tests are performed on sandwich coupons to characterize the stiffness and damping properties of the plates in a given frequency range. Resulting mechanical properties are then used to set-up a finite element model and simulate the plate dynamic response. In parallel, frequency response measurements are carried out on the manufactured plates, then successfully confronted to the numerical results.

The sheets are produced by the impact of drops on a quartz plate covered with a thin layer of liquid nitrogen that suppresses shear viscous dissipation as a result of the cold Leidenfrost effect. The time evolution of the sheet is simultaneously recorded from top and side views using high-speed cameras. The investigated viscoelastic fluids are Maxwell fluids, which are characterized by low elastic moduli, and relaxation times that vary over almost two orders of magnitude, thus giving access to a large spectrum of viscoelastic and elastocapillary effects. For the purposes of comparison, Newtonian fluids, with viscosity varying over three orders of magnitude, are also investigated. In this study, $d_{\\mathrm{max}}$, the maximal expansion of the sheets, and $t_{\\mathrm{max}}$ the time to reach this maximal expansion from the time at impact, are measured as a function of the impact velocity. By using a generalized damped harmonic oscillator model, we rationalize the role of capillarity, bulk elasticity and viscous dissipation in the expansion dynamics of all investigated samples. In the model, the spring constant is a combination of the surface tension and the bulk dynamic elastic modulus. The time-varying damping coefficient is associated to biaxial extensional viscous dissipation and is proportional to the dynamic loss modulus.

The present review, written on the occasion of the birth centenary of James Oldroyd, provides an overview of instabilities found across major classes of shearing flows. These comprise (i) the canonical rectilinear shearing flows including plane Couette, plane and pipe Poiseuille flows; (ii) viscometric shearing flows with curved streamlines such as those in the Taylor-Couette, cone-and-plate and parallel-plate geometries; (iii) non-viscometric shearing flows with an underlying extensional flow topology such as the flow in a cross-slot device; and (iv) multilayer shearing flows. While the underlying focus in all these cases is on results obtained using the Oldroyd-B model, we also discuss their relation to the actual instability, and as to how the shortcomings of the Oldroyd-B model may be overcome by the use of more realistic constitutive models. All the three commonly used tools of stability analysis, viz., modal linear stability, nonmodal stability, and weakly nonlinear stability analyses are discussed, with supporting evidence from experiments and numerical simulations as appropriate. Despite only accounting for a shear-rate-independent viscosity and first normal stress coefficient, the Oldroyd-B model is able to qualitatively predict the majority of instabilities in the aforementioned shearing flows.

In an iron chloride solution saturated with carbon dioxide, buffered with sodium bicarbonate to pH 6.8, roughly spherical particles of siderite formed within 15 min, which subsequently deposited on the QCMD crystal surface. Imaging of the surface showed a layer formed from particles ca. < 0.5 μm in diameter. Larger particles are clearly deposited on top of the lower layer; these larger particles are >1 μm in diameter. Monitoring of the frequency clearly differentiates the formation of the lower layer from the larger crystals deposited on top at later times. The elastic moduli calculated from QCMD data showed a progressive dissipation increase; the modeling of the solid-liquid interface using a flat approximation resulted in a poor estimation of elastic and storage moduli. Rather, the impedance modeled as a viscoelastic layer in contact with a semi-infinite liquid, where a random bumpy surface with a Gaussian correlator is used, is much more accurate in determining the elastic and storage moduli as losses from the uneven interface are considered. A further step considers that the film is in fact a composite consisting of hard spherical particles of siderite with water in the vacant spaces. This is treated by considering the individual contributions of the phases to the losses measured, thereby further improving the accuracy of the description of the film and the QCMD data.

We introduce a simple approach to calculate the effective relaxation time of viscoelastic interfaces and estimate the thickness of the interfacial layer and the viscoelastic properties of liquid-fluid interfaces, where the direct measurement of interfacial rheology is not possible.", - "journal": "Physical review letters", - "issn": [ - "1079-7114" - ], - "authors": [ - "Parisa Bazazi", - "Howard A Stone", - "S Hossein Hejazi" - ], - "doi": "10.1103/PhysRevLett.130.034001", - "publishedDate": "2022-12-20T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/36763387", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/36614435", - "title": "Active Vibration Control of Composite Cantilever Beams.", - "content": "This paper deals with the active vibration control of composite cantilever beam.

Owing to the growing consumer demand, the food industry is moving toward the growing use of plant-based proteins, suitable for consumers who do not eat products of animal origin, for either ethical or health reasons. Nevertheless, the scientific literature lacks information on the surface activity and emulsifying ability of these proteins. In this work, the interfacial properties of soy, hemp and brown rice isolate proteins were investigated at the interface with commercial sunflower oil (O/W) to evaluate their characteristics in view of potential uses in food applications such as emulsions, sauces, dressing, topping and soft foods. Dilatational and shear kinematic, with pendant drop and magnetic rod techniques, respectively, were used. The dilatational analysis was performed in static and dynamic conditions, to obtain the equilibrium adsorption isotherms and the rheological parameters of the interfacial layers under both oscillation and stress relaxation. The interfaces were studied in shear conditions with small amplitude oscillations and creep tests. The obtained results evidenced that all tested proteins are able to build a strong viscoelastic layer with properties comparable to those of animal proteins. Brown rice protein seems particularly effective in reducing the interfacial tension even if shear tests evidence that the interface is weaker than that obtained using hemp or soy protein.

The accurate and efficient determination of the frequency-dependent complex modulus of viscoelastic material is the basis for the correct analysis of the vibro-acoustic behavior of sandwich structures. Based on the behavior of a sandwich beam whose core is a viscoelastic layer, a combined theoretical and experimental study is proposed to characterize the properties of the viscoelastic layer constituting the core. In this method, the viscoelastic layer is bonded between two constraining layers. Then, a genetic algorithm is used to fit the analytical solution of the frequency¬ response function of the free-free constrained beam to the measured result, and then the frequency-dependent complex modulus is estimated for the viscoelastic layer. Moreover, by varying the length of the beams, it is possible to characterize the frequency-dependent complex modulus of the viscoelastic material over a wide frequency range. Finally, the characterized frequency-dependent complex modulus is imported into a finite element model to compute the complex natural frequencies of a sandwich beam, and a comparison of the simulated and measured results displays that the errors in the real parts are within 2.33% and the errors in the imaginary parts are within 3.31%.

The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics.

While role of solvents in enabling superior mechanical properties has been addressed before, outlined study is the first to address the effect of solvents on thermal conductivity enhancement and provides novel pathways for achieving high thermal conductivity polymer composite materials. Uniform dispersion of graphene nanoparticles into epoxy can improve thermal contact with polymer leading to superior interface thermal conductance between polymer matrix and graphene. Organic solvents are typically employed to achieve efficient dispersion of graphene into the epoxy matrix. In this study, we compare the effect of two organic solvents, dimethylformamide (DMF) and acetone, in terms of their efficiency in dispersing graphene into the epoxy matrix and their effect on enhancing thermal conductivity of the composite. We find that polymer-graphene composites made with DMF solvent show 44% higher thermal conductivity compared to those made using acetone at 7 weight% filler composition. Laser scanning confocal microscopy (LSCM) imaging reveals that graphene-epoxy composites, prepared using DMF as solvent, exhibit more uniform dispersion of graphene-nanoplatelets compared to the case of acetone with acetone-based samples exhibiting up to 211% larger graphene agglomerations. Comparison with effective medium theory reveals an almost 35% lower interface thermal resistance between graphene and epoxy for DMF relative to acetone prepared composite.

The addition of BE resulted in an increase in Tg in all tested blends. Blends with 50 wt% BE cured with TETA demonstrated an increase in flexural modulus and flexural strength, while preserving the elongation. Blends with 40 wt% BE cured with PEA4 and 50 wt% BE cured with DDS resulted in a significant enhanced tensile elongation. The shear strength of all cured systems decreased moderately with the addition of BE exhibiting a mixed mode failure. Analysis of the fracture morphology using electron microscopy supported the increase of toughness levels as a result of incorporating BE to conventional epoxy. A unique nodular and rough fracture morphology was obtained, which is related to a toughening mechanism caused by the addition of BE. It was concluded that blends of BE and conventional epoxy could be used as structural adhesives having high Tg, enhanced mechanical properties and increased toughness. POLYM. ENG.

Significant improvements in the understanding and calibration of the IR spectrometer response non-linearity, time-varying background level, flat field, wavelength map, and absolute spectral response have been achieved.

The consumption of epoxy resins is predicted to keep growing in the coming years. Unfortunately, thermoset resins cannot be recycled, and are typically not biodegradable.

These bacteria were isolated from soil samples collected from areas around an epoxy and polyurethanes manufacturing plant. Using an array of molecular, biochemical, analytical, and microscopic techniques, they were identified as Rhodococcus rhodochrous and Ochrobactrum anthropi. As epoxy was the only carbon source available for these bacteria, their measured growth rate reflected their ability to degrade epoxy resin. Bacterial growth took place only when the two bacteria were grown together, indicating a synergistic effect. The surface morphology of the epoxy droplets changed significantly due to the biodegradation process.

The processing of fiber-reinforced epoxy composite structures requires carefully selected heating and cooling cycles to fully cure the resin and form strong crosslinked networks. To fully optimize the processing parameters for effective epoxy monomer crosslinking and final product integrity, the evolution of mechanical properties of epoxies during processing must be comprehensively understood. Because the full experimental characterization of these properties as a function of the degree of cure is difficult and time-consuming, efficient computational predictive tools are needed. The objective of this research is to develop an experimentally validated Molecular Dynamics (MD) modeling method, which incorporates a reactive force field, to accurately predict the thermo-mechanical properties of an epoxy resin as a function of the degree of cure. Experimental rheometric and mechanical testing are used to validate an MD model which is subsequently used to predict mass density, shrinkage, elastic properties, and yield strength as a function of the degree of cure.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen. It was evident that the modulus of elasticity property of short fiber composites exhibits an increasing trend with higher fiber content, even at 35 wt%. Moreover, the enhancement of tensile strength for the short fiber size composites reached 72.5 %.

The commercial 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-Oxide (DOPO) with high reactive P-H bond is used as highly-efficient flame retardant in this work. Compared with pure epoxy resin with a limited oxygen index of 21.7 % and no rating in vertical burning test, recyclable epoxy resin only with 3 wt% DOPO acquires a limited oxygen index value of 27.8% and V-0 rating. In addition, REP composites containing 4 wt% DOPO displays quick self-extinguishing behavior, which shows the 43.5% drop of the peak heat release rate. The main reason might be that traditional phosphorous-containing flame retardant existing in REP composites can play a positive role in both condensed phase and gas phase when burning. On the other hand, both scanning electron microscopy and Raman results also further affirm the improved flame retardancy. Moreover, flame-retardant REP composites can also maintain good transparency and mechanical properties.

The anti-hyperglycemic effects of the FOD extract and the pure compounds were studied in mice using the Oral Glucose Tolerance Test (OGTT) and streptozotocin (STZ)-induced diabetes mellitus (DM) models. Molecular docking studies were performed on potent compounds in the binding pockets of enzymes α-glucosidase and α-amylase. The isolations of 11 compounds were isolated from the FOD extract, which comprised teferidine (1), ferutinin (FT) (2), teferin (3), epoxy-jaeschkeanadiol-p-hydroxybenzoate (4), epoxy-jaeschkeanadiol-6-vanillate (5), tovarol-8-angelate (6), leucoferin (7), tovarol-8-p-hydroxybenzoate (8), tovarol-8-vanillate (9), 6-β-p-hydroxybenzoyloxy-germacra-1(10),4-diene (10), and chimgin (11). Compounds 2 and 8-11 exhibited a higher inhibitory activity on α-glucosidase. In the OGTT, pretreatment with the FOD extract or compound 2 did not alter the BGLs after administration of the glucose solution compared to the control. In the STZ-induced diabetic mice model, no significant difference in the BGLs was observed with the FOD extract (200 mg/kg) or compound 2 (100 mg/kg)-treated diabetic mice compared to the diabetic control mice. The experimental studies all showed that the F. orientalis extract had significant effects on the enzyme systems involved in DM, and it would be appropriate to plan further studies on possible problems of bioavailability of the compound FT and the FOD extract, inadequate dose, and duration of administration.", - "journal": "Fitoterapia", - "issn": [ - "1873-6971" - ], - "authors": [ - "Nurdan Yazici", - "Seçkin Engin", - "Elif Nur Barut", - "Fadıl Kaan Kuran", - "Gozde Hasbal-Celikok", - "Tugba Yilmaz-Ozden", - "Mahmut Miski" - ], - "doi": "10.1016/j.fitote.2024.106225", - "publishedDate": "2024-09-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39321856", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1811.02943v1", - "title": "Deposition and Visualization of DNA Molecules on Graphene That is Obtained with the Aid of Mechanical Splitting on a Substrate with an Epoxy Sublayer", - "publishedDate": "2018-11-07T15:44:23", - "content": "Controlled deposition of DNA on graphene films obtained with the aid of mechanical splitting of graphite on a substrate with an epoxy sublayer is demonstrated.

The obtained EPFs provide a Tg of 150–154 °C. The fusion boundaries in EPFs are well formed.

They are produced by integrating thin sandwich structures of CNT fiber veils and an ionic liquid-based polymer electrolyte between carbon fiber plies, followed by infusion and curing of an epoxy resin. The resulting structure behaves simultaneously as an electric double-layer capacitor and a structural composite, with flexural modulus of 60 GPa and flexural strength of 153 MPa, combined with 88 mF/g of specific capacitance and the highest power (30 W/kg) and energy (37.5 mWh/kg) densities reported so far for structural supercapacitors. In-situ electrochemical measurements during 4-point bending show that electrochemical performance is retained up to fracture, with minor changes in equivalent series resistance for interleaves under compressive stress. En route to improving interlaminar properties we produce grid-shaped interleaves that enable mechanical interconnection of plies by the stiff epoxy. Synchrotron 3D X-ray tomography analysis of the resulting hierarchical structure confirms the formation of interlaminar epoxy joints.

This would reduce carbon emissions due to electricity generation, and also help to decarbonize other sources such as automotive and heating by enabling a low-carbon alternative. Carbon taxes have been shown to be an efficient way to aid in this transition. In this paper, we demonstrate how to to find optimal carbon tax policies through a genetic algorithm approach, using the electricity market agent-based model ElecSim. To achieve this, we use the NSGA-II genetic algorithm to minimize average electricity price and relative carbon intensity of the electricity mix. We demonstrate that it is possible to find a range of carbon taxes to suit differing objectives.

In a first-best setting, the optimal use of CDR is achieved by a removal subsidy that equals the optimal carbon tax and marginal damages. We derive second-best policy rules for CDR subsidies and carbon taxes when no global carbon price exists but a national government implements a unilateral climate policy. We find that the optimal carbon tax differs from an optimal CDR subsidy because of carbon leakage and a balance of resource trade effect. First, the optimal removal subsidy tends to be larger than the carbon tax because of lower supply-side leakage on fossil resource markets. Second, net carbon exporters exacerbate this wedge to increase producer surplus of their carbon resource producers, implying even larger removal subsidies.

To address this problem, we design an \"ecovisor\", which virtualizes the energy system and exposes software-defined control of it to applications. An ecovisor enables each application to handle clean energy's unreliability in software based on its own specific requirements. We implement a small-scale ecovisor prototype that virtualizes a physical energy system to enable software-based application-level i) visibility into variable grid carbon-intensity and renewable generation and ii) control of server power usage and battery charging/discharging.

Motivated by adversarial attacks, researchers have devoted considerable efforts to enhancing model robustness by adversarial training (AT). However, we observe that while AT improves the models' robustness against adversarial perturbations, it fails to improve their ability to effectively extract features across all frequency components. Each frequency component contains distinct types of crucial information: low-frequency features provide fundamental structural insights, while high-frequency features capture intricate details and textures. In particular, AT tends to neglect the reliance on susceptible high-frequency features. This low-frequency bias impedes the model's ability to effectively leverage the potentially meaningful semantic information present in high-frequency features. This paper proposes a novel module called High-Frequency Feature Disentanglement and Recalibration (HFDR), which separates features into high-frequency and low-frequency components and recalibrates the high-frequency feature to capture latent useful semantics. Additionally, we introduce frequency attention regularization to magnitude the model's extraction of different frequency features and mitigate low-frequency bias during AT.

In this paper, we seek to demystify this relationship by exploring the characteristics of adversarial perturbations within the frequency domain. We employ wavelet packet decomposition for detailed frequency analysis of adversarial examples and conduct statistical examinations across various frequency bands. Intriguingly, our findings indicate that significant adversarial perturbations are present within the high-frequency components of low-frequency bands. Drawing on this insight, we propose a black-box adversarial attack algorithm based on combining different frequency bands. Experiments conducted on multiple datasets and models demonstrate that combining low-frequency bands and high-frequency components of low-frequency bands can significantly enhance attack efficiency.

Here we show that strontium titanate and potassium tantalate, materials which can exhibit quantum paraelectric behaviour with large field-tunable permittivity at low temperatures, can be used to make varactors with perfect impedance matching and resonator frequency tuning at 6 mK. We characterize the varactors at 6 mK in terms of their capacitance tunability, dissipative losses and magnetic field insensitivity.

For the purpose, we first design a Time Transformer and Frequency Transformer to capture the local emotion patterns between frames and inside frequency bands respectively, so as to ensure the integrity of the emotion information modeling in both time and frequency domains. Then, a Time-Frequency Transformer is proposed to mine the time-frequency emotional correlations through the local time-domain and frequency-domain emotion features for learning more discriminative global speech emotion representation.

Specifically, this paper reveals a linear micro frequency hopping symbol with good auto-correlation and cross-correlation feature in both time domain and frequency domain. Linear micro frequency hopping symbols with different root $R$ have good cross-correlation feature, which can be used in multi-user communication at same time and same frequency. Moreover, there is a linear relationship between the time delay and frequency offset of this linear micro frequency hopping symbol, making it suitable for time delay and frequency offset estimation, also for ranging, and speed measurement. Finally, this paper also verifies the advantages of micro frequency hopping technology through an example of a linear micro frequency hopping spread spectrum multiple access communication system.

Such frequency combs allow counting of optical frequencies and have a wide range of applications. The required optical bandwidth to implement self-referencing is typically obtained via nonlinear broadening in optical fibers. Recent advances in the field of Kerr frequency combs have provided a path towards the development of compact frequency comb sources that provide broadband frequency combs, exhibit microwave repetition rates and that are compatible with on-chip photonic integration. These devices have the potential to significantly expand the use of frequency combs. Yet to date self-referencing of such Kerr frequency combs has only been attained by applying conventional, fiber based broadening techniques. Here we demonstrate external broadening-free self-referencing of a Kerr frequency comb. An optical spectrum that spans two-thirds of an octave is directly synthesized from a continuous wave laser-driven silicon nitride microresonator using temporal dissipative Kerr soliton formation and soliton Cherenkov radiation. Using this coherent bandwidth and two continuous wave transfer lasers in a 2f-3f self-referencing scheme, we are able to detect the offset frequency of the soliton Kerr frequency comb. By stabilizing the repetition rate to a radio frequency reference the self-referenced frequency comb is used to count and track the continuous wave pump laser's frequency.

The aim of this study is to visualize and quantify the ghost spectral lines produced by two, three and four interleaved echo trains with different amplitudes of the readout gradients, and to investigate the feasibility of the flyback data acquisition in micro-imaging of small animals. Applied multi-slice EPSI sequence utilizes asymmetric gradient-echo train that combines the shortest possible rewind gradients with readout gradients. It simplifies data processing because all echoes are acquired with the same polarity of the readout gradient. The approach with four interleaved gradient-echo trains and with four echoes in each train provides broad spectral bandwidth in combination with narrow receiver bandwidth and a good water-fat signal separation. It improves signal-to-noise ratio without the undesired consequence of water-fat shift artifacts that are eliminated during data processing. Position, number, and intensity of the ghost spectral lines can be controlled by the suitable choice of spectral bandwidth, number of echo train interleaves, and the number of echoes in each interleave.

Comparing scalar fields using their topological descriptors has many applications in topological data analysis and visualization of scientific data. Recently, Munch and Stefanou introduced a labeled interleaving distance for comparing two labeled merge trees, which enjoys a number of theoretical and algorithmic properties. In particular, the labeled interleaving distance between merge trees can be computed in polynomial time. In this work, we define the labeled interleaving distance for labeled Reeb graphs. We then prove that the (ordinary) interleaving distance between Reeb graphs equals the minimum of the labeled interleaving distance over all labelings. We also provide an efficient algorithm for computing the labeled interleaving distance between two labeled contour trees (which are special types of Reeb graphs that arise from simply-connected domains). In the case of merge trees, the notion of the labeled interleaving distance was used by Gasparovic et al. to prove that the (ordinary) interleaving distance on the set of (unlabeled) merge trees is intrinsic. As our final contribution, we present counterexamples showing that, on the contrary, the (ordinary) interleaving distance on (unlabeled) Reeb graphs (and contour trees) is not intrinsic. It turns out that, under mild conditions on the labelings, the labeled interleaving distance is a metric on isomorphism classes of Reeb graphs, analogous to the ordinary interleaving distance.

The interleaving distance, in turn, is a common distance measure for comparing merge trees. However, the interleaving distance for merge trees is solely based on the hierarchical structure, and disregards any other geometrical or topological properties that might be present in the underlying data. Furthermore, the interleaving distance is NP-hard to compute. In this paper, we introduce a form of ordered merge trees that does capture intrinsic order present in the data. We further define a natural variant of the interleaving distance, the monotone interleaving distance, which is an order preserving distance measure for ordered merge trees. Analogous to the regular interleaving distance for merge trees, we show that the monotone variant has three equivalent definitions in terms of two maps, a single map, or a labelling. The labelling-based definition fairly directly leads to an efficient algorithm for computing the monotone interleaving distance, but unfortunately it computes only an approximation thereof. Instead, we discover a surprising connection between the monotone interleaving distance of ordered merge trees and the Fr\\'{e}chet distance of 1D curves. As a result, the monotone interleaving distance between two ordered merge trees of total complexity $n$ can be computed exactly in $\\tilde O(n^2)$ time.

The strong echogenicity of accumulated MBs also improves diagnostics via conventional ultrasound (US) B-mode imaging. However, the annular high-pressure distribution of AVT inhibits MBs inflow at the inlet, reducing MBs collection. The spatial resolution of US B-mode imaging further limits theranostic applications of AVT-mediated MBs accumulation. To address these challenges, we integrated an AVT waveform with volumetric super-resolution imaging (VSRI) to monitor the dynamic growth of MBs cluster during accumulation. We used a 5-MHz 2D array transducer for VSRI, employing plane wave pulses interleaved with accumulating pulses to retain MBs at a flow rate of 0.023-0.047 mL/s in a 3-mm vessel phantom. An asymmetrical AVT waveform (AVT*) was produced by modulating the pressure at the MBs inlet compared to the outlet. The effectiveness was validated in rat cerebral vessels for real-time volumetric tracking of MBs clusters. Microscopy observations showed that AVT* could quickly gather flowing MBs into cluster without repelling them at a flow rate of 0.023 mL/s. Statistical results indicated that microscopic data correlated better with VSRI than with B-mode images, suggesting VSRI suffices to detect the dynamics of AVT*-actuated MBs accumulation in real-time. Additionally, VSRI detected a significant increase in MBs cluster size over time during AVT* in the superior sagittal sinus of the rat brain.

Vascular malformations are rare and complex abnormalities that affect both children and young adults. Low-flow malformations are more common in children and often become symptomatic in later years. These malformations are common causes of soft tissue masses in children and can affect any part of the body at any age. Significant advancements in the management of these conditions have been made due to the implementation of a comprehensive binary categorization system, which classifies vascular abnormalities into tumors and malformations based on their clinicopathological characteristics. Imaging, particularly magnetic resonance imaging (MRI), plays a crucial role in the accurate identification, localization, and classification of these lesions, aiding in the development of appropriate treatment plans. Materials and methods This prospective study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune, from August 2022 to June 2024. Fifty patients of all age groups with clinically suspected soft tissue vascular malformations were included. MRI was performed using a MAGNETOM Vida (3T) Scanner (Siemens Healthcare Private Limited, Mumbai, India), and ultrasound was used as an adjunct. Institutional Ethics Committee clearance and informed consent were obtained. The study employed various MRI sequences, including T1-weighted imaging (T1WI) fast spin echo (FSE), T2-weighted imaging (T2WI) FSE, short tau inversion recovery (STIR), T2-weighted gradient recalled echo (GRE), pre-contrast fat-saturated T1WI, 3D post-contrast T1WI, diffusion-weighted imaging (DWI), and ANGIO TWIST (time-resolved angiography with interleaved stochastic trajectories) ISO. Results The study included 50 patients, with a male predominance of 28 (56%). The mean age was 22.13 years, and the average duration of vascular malformations was 32.94 months. The swelling was present in 43 (86%) of patients, and 35 (70%) had superficial lesions. MRI findings revealed hypointensity on T1 imaging in 40 (80%) patients and hyperintensity on T2 imaging in 49 (98%) cases. STIR sequences showed hyperintensity in all patients. The most common type of vascular malformation was slow-flow 46 (92%), with venous malformations being the most prevalent 39 (78%). Conclusion MRI is a valuable imaging modality for the evaluation and classification of vascular malformations, providing detailed information on lesion extent and involvement of surrounding tissues. The findings support the use of MRI as a primary tool in the assessment of vascular malformations, with ultrasound serving as a useful adjunct in certain cases. Further studies with larger sample sizes are recommended to validate these findings and refine imaging protocols.", - "journal": "Cureus", - "issn": [ - "2168-8184" - ], - "authors": [ - "Rajesh Kuber", - "Prajakta P KirdatPatil", - "Aryaman Dhande", - "Rahul Mane", - "Pushkar Kumar" - ], - "doi": "10.7759/cureus.67475", - "publishedDate": "2024-08-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39310382", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2004.14286v1", - "title": "A Relative Theory of Interleavings", - "publishedDate": "2020-04-29T16:05:45", - "content": "The interleaving distance, although originally developed for persistent homology, has been generalized to measure the distance between functors modeled on many posets or even small categories.

In this paper we show how one can side-step this limitation by providing a general theory where one maps to a poset that does admit interesting translations, such as the lattice of down sets, and then defines interleavings relative to this map. Part of our theory includes a rigorous notion of discretization or \"pixelization\" of poset modules, which in turn we use for interleaving inference. We provide an approximation condition that in the setting of lattices gives rise to two possible pixelizations, both of which are guaranteed to be close in the interleaving distance.

The categorical viewpoint gives an immediate construction for a host of stability theorems. Further, a new construction on elements of a category with a flow called a hom-tree provides a lower bound for the interleaving distance.

Across four sessions, 28 participants were trained on an artificial language, which included two types of morphologically complex words: linear (root + suffix) with a salient structure, and non-linear (root interleaved with template), with a prominent derivational structure in participants' first language (L1). A third simple monomorphemic condition, which served as baseline, was also included. On the first and fourth sessions, training was followed by testing in an fMRI scanner. Our behavioural results showed decomposition of both types of complex words, with the linear structure more easily learned than the non-linear structure. Our fMRI results showed involvement of frontal areas, associated with decomposition, only for the non-linear condition, after just the first session. We also observed training-related increases in activation in temporal areas specifically for the non-linear condition, which was correlated with participants' L1 morphological awareness. These results demonstrate that morphological decomposition of derived words occurs in the very early stages of word learning, is influenced by L1 experience, and can facilitate word learning. However, in contrast to the CLS framework, we found no support for a shift from reliance on hippocampus to reliance on cortical areas in any of our conditions. Instead, our findings align more closely with recent theories showing a positive correlation between changes in hippocampus and cortical areas, suggesting that these representations co-exist and continue to interact with one another beyond initial learning.", - "journal": "Neurobiology of language (Cambridge, Mass.)", - "issn": [ - "2641-4368" - ], - "authors": [ - "Upasana Nathaniel", - "Stav Eidelsztein", - "Kate Girsh Geskin", - "Brianna L Yamasaki", - "Bracha Nir", - "Vedran Dronjic", - "James R Booth", - "Tali Bitan" - ], - "doi": "10.1162/nol_a_00150", - "publishedDate": "2024-06-07T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39301207", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2101.02441v1", - "title": "Interleaving of path sets", - "publishedDate": "2021-01-07T09:20:13", - "content": "Path sets are spaces of one-sided infinite symbol sequences corresponding to the one-sided infinite walks beginning at a fixed initial vertex in a directed labeled graph.

HER4 (ErbB4) is the least studied member of this family, partly because its expression is lower in later stages of development. Recent work has suggested that HER4 can play a role in metastasis by regulating cell migration and invasiveness; however, unlike EGFR and HER2, the precise role that HER4 plays in tumorigenesis is still unresolved. Early work on HER family proteins suggested that there are direct interactions between the four members, but to date, there has been no single study of all four receptors in the same cell line with the same biophysical method. Here, we quantitatively measure the degree of association between HER4 and the other HER family proteins in live cells with a time-resolved fluorescence technique called pulsed interleaved excitation fluorescence cross-correlation spectroscopy (PIE-FCCS). PIE-FCCS is sensitive to the oligomerization state of membrane proteins in live cells, while simultaneously measuring single-cell protein expression levels and diffusion coefficients. Our PIE-FCCS results demonstrate that HER4 interacts directly with all HER family members in the cell plasma membrane. The interaction between HER4 and other HER family members intensified in the presence of a HER4-specific ligand.

To motivate these axioms, we also observe that $d_{HI}$ (or more generally, any pseudometric satisfying these two axioms and an additional \"homology bounding\" axiom) can be used to formulate lifts of several fundamental TDA theorems from the algebraic (homological) level to the level of filtered spaces.

In this regard, as a first step a cascaded meta-atom composed of square rings and/or square metallic patches separated by two polyimide substrates is designed and optimized that provides sixteen independent distinct discrete phases in the reflection geometry. These meta-atoms are then distributed with distinct coding sequences in the two-dimensional spatial plane to realize various bi-functional metasurfaces. As a proof of the concept various full structures are designed and simulated to realize a series of bi-functionalities including anomalous reflection/beam shaping, beam shaping/anomalous reflection, beam deflection/Orbital angular momentum (OAM) beam generation with distinct modes and propagating wave to surface wave (PW-SW) conversion/PW beam manipulation in the lower and higher THz bands, respectively. All the simulation results are in excellent agreement with their theoretical equivalents.

We propose a novel machine learning framework referred to as interleaving learning (IL). In our framework, a set of models collaboratively learn a data encoder in an interleaving fashion: the encoder is trained by model 1 for a while, then passed to model 2 for further training, then model 3, and so on; after trained by all models, the encoder returns back to model 1 and is trained again, then moving to model 2, 3, etc. This process repeats for multiple rounds. Our framework is based on multi-level optimization consisting of multiple inter-connected learning stages. An efficient gradient-based algorithm is developed to solve the multi-level optimization problem.

One solution to this dilemma is to use interleaved training to learn a single representation that accommodates all schemas. However, another class of models posits that catastrophic interference can be avoided by splitting off new representations when large prediction errors occur. A key differentiating prediction is that, according to splitting models, catastrophic interference can be prevented even under blocked training curricula. We conducted a series of semi-naturalistic experiments and simulations with Bayesian and neural network models to compare the predictions made by the \"splitting\" versus \"non-splitting\" hypotheses of schema learning. We found better performance in blocked compared to interleaved curricula, and explain these results using a Bayesian model that incorporates representational splitting in response to large prediction errors. In a follow-up experiment, we validated the model prediction that inserting blocked training early in learning leads to better learning performance than inserting blocked training later in learning.

The main objective of this work is to contribute for a better understanding of the static behavior of structure made from fiber reinforced composite materials, specifically for the case of plate structures. The plate model is created using SOLIDWORKS 2017 and then imported into ANSYS R18.1. The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity. This suggests that the composite plate with a cross ply configuration is more suitable for manufacturing composite structures due to its improved performance.", - "journal": "Heliyon", - "issn": [ - "2405-8440" - ], - "authors": [ - "Chala Amsalu", - "Debela Negasa", - "Amanu Merga" - ], - "doi": "10.1016/j.heliyon.2024.e37698", - "publishedDate": "2024-09-09T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39328535", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 1 - ], - "score": 1.0, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2312.07149v1", - "title": "Feature-based prediction of properties of cross-linked epoxy polymers by molecular dynamics and machine learning techniques", - "publishedDate": "2023-12-12T10:39:00", - "content": "Epoxy polymers are used in wide range of applications. The properties and performance of epoxy polymers depend upon various factors like the type of constituents and their proportions used and other process parameters. The conventional way of developing epoxy polymers is usually labor-intensive and may not be fully efficient, which has resulted in epoxy polymers having a limited performance range due to the use of predetermined blend combinations, compositions and development parameters. Hence, in order to experiment with more design parameters, robust and easy computational techniques need to be established. To this end, we developed and analyzed in this study a new machine learning (ML) based approach to predict the mechanical properties of epoxy polymers based on their basic structural features. The results from molecular dynamics (MD) simulations have been used to derive the ML model. The salient feature of our work is that for the development of epoxy polymers based on EPON-862, several new hardeners were explored in addition to the conventionally used ones. The influence of additional parameters like the proportion of curing agent used and the extent of curing on the mechanical properties of epoxy polymers were also investigated. This method can be further extended by providing the epoxy polymer with the desired properties through knowledge of the structural characteristics of its constituents.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics.

While role of solvents in enabling superior mechanical properties has been addressed before, outlined study is the first to address the effect of solvents on thermal conductivity enhancement and provides novel pathways for achieving high thermal conductivity polymer composite materials. Uniform dispersion of graphene nanoparticles into epoxy can improve thermal contact with polymer leading to superior interface thermal conductance between polymer matrix and graphene. Organic solvents are typically employed to achieve efficient dispersion of graphene into the epoxy matrix. In this study, we compare the effect of two organic solvents, dimethylformamide (DMF) and acetone, in terms of their efficiency in dispersing graphene into the epoxy matrix and their effect on enhancing thermal conductivity of the composite. We find that polymer-graphene composites made with DMF solvent show 44% higher thermal conductivity compared to those made using acetone at 7 weight% filler composition. Laser scanning confocal microscopy (LSCM) imaging reveals that graphene-epoxy composites, prepared using DMF as solvent, exhibit more uniform dispersion of graphene-nanoplatelets compared to the case of acetone with acetone-based samples exhibiting up to 211% larger graphene agglomerations. Comparison with effective medium theory reveals an almost 35% lower interface thermal resistance between graphene and epoxy for DMF relative to acetone prepared composite.

The processing of fiber-reinforced epoxy composite structures requires carefully selected heating and cooling cycles to fully cure the resin and form strong crosslinked networks.

The objective of this research is to develop an experimentally validated Molecular Dynamics (MD) modeling method, which incorporates a reactive force field, to accurately predict the thermo-mechanical properties of an epoxy resin as a function of the degree of cure. Experimental rheometric and mechanical testing are used to validate an MD model which is subsequently used to predict mass density, shrinkage, elastic properties, and yield strength as a function of the degree of cure.

This problem relates to oscillating blood flow in viscoelastic vessels. The deeper motivation for this study, however, is the possible use of compliant coatings for turbulent drag reduction. An analytical solution of the fluid and solid velocity is presented, and five dimensionless parameters emerge. The interaction between fluid and solid appears to be determined by a single combined dimensionless parameter, which we call the shear interaction parameter $\\chi$. The fluid satisfies a no-slip boundary condition when $\\left|\\chi\\right| \\rightarrow 0$, which occurs when the solid is heavy, stiff and/or thin. In contrast, the fluid obeys a free-slip boundary condition when $\\left|\\chi\\right| \\rightarrow \\infty$, which corresponds to a lightweight and/or soft solid. Three types of resonance modes are identified for an elastic solid. Two modes (odd and even) are specific to the solid. The third mode results from the coupling with the fluid. The three modes are less pronounced or even absent for a viscoelastic solid. These findings have a twofold use. First, they help to understand the fluid and solid dynamics when shear coupling is important.

The commercial 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-Oxide (DOPO) with high reactive P-H bond is used as highly-efficient flame retardant in this work. Compared with pure epoxy resin with a limited oxygen index of 21.7 % and no rating in vertical burning test, recyclable epoxy resin only with 3 wt% DOPO acquires a limited oxygen index value of 27.8% and V-0 rating. In addition, REP composites containing 4 wt% DOPO displays quick self-extinguishing behavior, which shows the 43.5% drop of the peak heat release rate. The main reason might be that traditional phosphorous-containing flame retardant existing in REP composites can play a positive role in both condensed phase and gas phase when burning. On the other hand, both scanning electron microscopy and Raman results also further affirm the improved flame retardancy. Moreover, flame-retardant REP composites can also maintain good transparency and mechanical properties.

In an iron chloride solution saturated with carbon dioxide, buffered with sodium bicarbonate to pH 6.8, roughly spherical particles of siderite formed within 15 min, which subsequently deposited on the QCMD crystal surface. Imaging of the surface showed a layer formed from particles ca. < 0.5 μm in diameter. Larger particles are clearly deposited on top of the lower layer; these larger particles are >1 μm in diameter. Monitoring of the frequency clearly differentiates the formation of the lower layer from the larger crystals deposited on top at later times. The elastic moduli calculated from QCMD data showed a progressive dissipation increase; the modeling of the solid-liquid interface using a flat approximation resulted in a poor estimation of elastic and storage moduli. Rather, the impedance modeled as a viscoelastic layer in contact with a semi-infinite liquid, where a random bumpy surface with a Gaussian correlator is used, is much more accurate in determining the elastic and storage moduli as losses from the uneven interface are considered. A further step considers that the film is in fact a composite consisting of hard spherical particles of siderite with water in the vacant spaces. This is treated by considering the individual contributions of the phases to the losses measured, thereby further improving the accuracy of the description of the film and the QCMD data.

This problem relates to oscillating blood flow in viscoelastic vessels. The deeper motivation for this study, however, is the possible use of compliant coatings for turbulent drag reduction. An analytical solution of the fluid and solid velocity is presented, and five dimensionless parameters emerge. The interaction between fluid and solid appears to be determined by a single combined dimensionless parameter, which we call the shear interaction parameter $\\chi$. The fluid satisfies a no-slip boundary condition when $\\left|\\chi\\right| \\rightarrow 0$, which occurs when the solid is heavy, stiff and/or thin. In contrast, the fluid obeys a free-slip boundary condition when $\\left|\\chi\\right| \\rightarrow \\infty$, which corresponds to a lightweight and/or soft solid. Three types of resonance modes are identified for an elastic solid. Two modes (odd and even) are specific to the solid. The third mode results from the coupling with the fluid. The three modes are less pronounced or even absent for a viscoelastic solid. These findings have a twofold use. First, they help to understand the fluid and solid dynamics when shear coupling is important. Second, the presented analytical solution is very useful for validation of numerical fluid-structure-interaction solvers.

The MPJR finite elements, previously developed for partial slip contact problems, are herein further generalized in order to deal with finite sliding displacements. The approach is applied to a case study concerning a periodic contact problem between a sinusoidal profile and a viscoelastic layer of finite thickness. In particular, the effect of using three different rheological models that are based on Prony series (with one, two, or three arms) to approximate the viscoelastic behaviour of a real polymer is investigated. The method allows for predicting the whole transient regime during the normal contact problem and the subsequent sliding scenario from full stick to full slip, and then up to gross sliding. The effects of the viscoelastic model approximation and of the sliding velocities are carefully investigated. The proposed approach aims at tackling a class of problems that are difficult to address with other methods, which include the possibility of analysing indenters of generic profile, the capability of simulating partial slip and gross slip due to finite slidings, and, finally, the possibility of simultaneously investigating dissipative phenomena, like viscoelastic dissipation and energy losses due to interface friction.", - "doi": "10.3390/lubricants8120107", - "authors": [ - "Jacopo Bonari", - "Marco Paggi" - ], - "journal": "Lubricants 2020, 8(12), 107", - "tags": [ - "cond-mat.soft" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2110.07886v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2110.07886v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 6 - ], - "score": 0.16666666666666666, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/36763387", - "title": "Dynamics of Droplet Pinch-Off at Emulsified Oil-Water Interfaces: Interplay between Interfacial Viscoelasticity and Capillary Forces.", - "content": "The presence of submicrometer structures at liquid-fluid interfaces modifies the properties of many science and technological systems by lowering the interfacial tension, creating tangential Marangoni stresses, and/or inducing surface viscoelasticity.

A way to achieve this is to decarbonize the electricity grid. However, further efforts must be made in other fields such as transport and heating for full decarbonization. This would reduce carbon emissions due to electricity generation, and also help to decarbonize other sources such as automotive and heating by enabling a low-carbon alternative. Carbon taxes have been shown to be an efficient way to aid in this transition. In this paper, we demonstrate how to to find optimal carbon tax policies through a genetic algorithm approach, using the electricity market agent-based model ElecSim. To achieve this, we use the NSGA-II genetic algorithm to minimize average electricity price and relative carbon intensity of the electricity mix. We demonstrate that it is possible to find a range of carbon taxes to suit differing objectives. Our results show that we are able to minimize electricity cost to below \\textsterling10/MWh as well as carbon intensity to zero in every case. In terms of the optimal carbon tax strategy, we found that an increasing strategy between 2020 and 2035 was preferable.

In a first-best setting, the optimal use of CDR is achieved by a removal subsidy that equals the optimal carbon tax and marginal damages. We derive second-best policy rules for CDR subsidies and carbon taxes when no global carbon price exists but a national government implements a unilateral climate policy. We find that the optimal carbon tax differs from an optimal CDR subsidy because of carbon leakage and a balance of resource trade effect. First, the optimal removal subsidy tends to be larger than the carbon tax because of lower supply-side leakage on fossil resource markets. Second, net carbon exporters exacerbate this wedge to increase producer surplus of their carbon resource producers, implying even larger removal subsidies. Third, net carbon importers may set their removal subsidy even below their carbon tax when marginal environmental damages are small, to appropriate producer surplus from carbon exporters.", - "doi": "10.1016/j.jeem.2022.102769", - "authors": [ - "Max Franks", - "Matthias Kalkuhl", - "Kai Lessmann" - ], - "journal": "Journal of Environmental Economics and Management 2022 102769", - "tags": [ - "econ.GN", - "q-fin.EC" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2212.09299v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2212.09299v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/36413907", - "title": "Interfacial behavior of vegetable protein isolates at sunflower oil/water interface.", - "content": "Proteins are widely used in the formation and stabilization of multiphase systems, thanks to their ability to adsorb at the interface reducing the interfacial tension and promoting the formation of viscoelastic layers. Owing to the growing consumer demand, the food industry is moving toward the growing use of plant-based proteins, suitable for consumers who do not eat products of animal origin, for either ethical or health reasons. Nevertheless, the scientific literature lacks information on the surface activity and emulsifying ability of these proteins. In this work, the interfacial properties of soy, hemp and brown rice isolate proteins were investigated at the interface with commercial sunflower oil (O/W) to evaluate their characteristics in view of potential uses in food applications such as emulsions, sauces, dressing, topping and soft foods. Dilatational and shear kinematic, with pendant drop and magnetic rod techniques, respectively, were used. The dilatational analysis was performed in static and dynamic conditions, to obtain the equilibrium adsorption isotherms and the rheological parameters of the interfacial layers under both oscillation and stress relaxation. The interfaces were studied in shear conditions with small amplitude oscillations and creep tests. The obtained results evidenced that all tested proteins are able to build a strong viscoelastic layer with properties comparable to those of animal proteins. Brown rice protein seems particularly effective in reducing the interfacial tension even if shear tests evidence that the interface is weaker than that obtained using hemp or soy protein. Hemp protein seems very promising for potential practical uses yielding intermediate interfacial tensions and strong viscoelastic layers.", - "journal": "Colloids and surfaces.

This problem relates to oscillating blood flow in viscoelastic vessels. The deeper motivation for this study, however, is the possible use of compliant coatings for turbulent drag reduction. An analytical solution of the fluid and solid velocity is presented, and five dimensionless parameters emerge. The interaction between fluid and solid appears to be determined by a single combined dimensionless parameter, which we call the shear interaction parameter $\\chi$. The fluid satisfies a no-slip boundary condition when $\\left|\\chi\\right| \\rightarrow 0$, which occurs when the solid is heavy, stiff and/or thin. In contrast, the fluid obeys a free-slip boundary condition when $\\left|\\chi\\right| \\rightarrow \\infty$, which corresponds to a lightweight and/or soft solid. Three types of resonance modes are identified for an elastic solid. Two modes (odd and even) are specific to the solid. The third mode results from the coupling with the fluid. The three modes are less pronounced or even absent for a viscoelastic solid. These findings have a twofold use. First, they help to understand the fluid and solid dynamics when shear coupling is important. Second, the presented analytical solution is very useful for validation of numerical fluid-structure-interaction solvers. Future work might include the extension of the theory to multiple viscoelastic layers and the dynamic coupling of normal stresses.", - "doi": null, - "authors": [ - "H. O. G. Benschop", - "W. -P.

The aim of this study is to visualize and quantify the ghost spectral lines produced by two, three and four interleaved echo trains with different amplitudes of the readout gradients, and to investigate the feasibility of the flyback data acquisition in micro-imaging of small animals. Applied multi-slice EPSI sequence utilizes asymmetric gradient-echo train that combines the shortest possible rewind gradients with readout gradients. It simplifies data processing because all echoes are acquired with the same polarity of the readout gradient. The approach with four interleaved gradient-echo trains and with four echoes in each train provides broad spectral bandwidth in combination with narrow receiver bandwidth and a good water-fat signal separation. It improves signal-to-noise ratio without the undesired consequence of water-fat shift artifacts that are eliminated during data processing. Position, number, and intensity of the ghost spectral lines can be controlled by the suitable choice of spectral bandwidth, number of echo train interleaves, and the number of echoes in each interleave.

The lift force is zero when the viscoelastic layer is not deformed, but becomes non-zero when it is deformed. We calculate the lift force by considering both the tangential stress and the normal stress applied at the surface of the viscoelastic layer. Our analysis indicates that as the layer changes from the elastic limit to the viscous limit, the lift force decreases with the decrease of the Deborah number (De). For small De, the effect of the layer elasticity is taken over by the surface tension and the lift force can become negative.

However, the annular high-pressure distribution of AVT inhibits MBs inflow at the inlet, reducing MBs collection. The spatial resolution of US B-mode imaging further limits theranostic applications of AVT-mediated MBs accumulation. To address these challenges, we integrated an AVT waveform with volumetric super-resolution imaging (VSRI) to monitor the dynamic growth of MBs cluster during accumulation. We used a 5-MHz 2D array transducer for VSRI, employing plane wave pulses interleaved with accumulating pulses to retain MBs at a flow rate of 0.023-0.047 mL/s in a 3-mm vessel phantom. An asymmetrical AVT waveform (AVT*) was produced by modulating the pressure at the MBs inlet compared to the outlet. The effectiveness was validated in rat cerebral vessels for real-time volumetric tracking of MBs clusters. Microscopy observations showed that AVT* could quickly gather flowing MBs into cluster without repelling them at a flow rate of 0.023 mL/s. Statistical results indicated that microscopic data correlated better with VSRI than with B-mode images, suggesting VSRI suffices to detect the dynamics of AVT*-actuated MBs accumulation in real-time. Additionally, VSRI detected a significant increase in MBs cluster size over time during AVT* in the superior sagittal sinus of the rat brain. These findings demonstrate that the proposed strategy can accumulate the flowing MBs at a desired location and simultaneously observe this phenomenon.", - "journal": "IEEE transactions on ultrasonics, ferroelectrics, and frequency control", - "issn": [ - "1525-8955" - ], - "authors": [ - "Ching-Hsiang Fan", - "Wei-Chen Lo", - "Chung-Han Huang", - "Thi-Nhan Phan", - "Chih-Kuang Yeh" - ], - "doi": "10.1109/TUFFC.2024.3466119", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39312432", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2306.01186v1", - "title": "Labeled Interleaving Distance for Reeb Graphs", - "publishedDate": "2023-06-01T22:55:35", - "content": "Merge trees, contour trees, and Reeb graphs are graph-based topological descriptors that capture topological changes of (sub)level sets of scalar fields.

Vascular malformations are rare and complex abnormalities that affect both children and young adults. Low-flow malformations are more common in children and often become symptomatic in later years. These malformations are common causes of soft tissue masses in children and can affect any part of the body at any age. Significant advancements in the management of these conditions have been made due to the implementation of a comprehensive binary categorization system, which classifies vascular abnormalities into tumors and malformations based on their clinicopathological characteristics. Imaging, particularly magnetic resonance imaging (MRI), plays a crucial role in the accurate identification, localization, and classification of these lesions, aiding in the development of appropriate treatment plans. Materials and methods This prospective study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune, from August 2022 to June 2024. Fifty patients of all age groups with clinically suspected soft tissue vascular malformations were included. MRI was performed using a MAGNETOM Vida (3T) Scanner (Siemens Healthcare Private Limited, Mumbai, India), and ultrasound was used as an adjunct. Institutional Ethics Committee clearance and informed consent were obtained. The study employed various MRI sequences, including T1-weighted imaging (T1WI) fast spin echo (FSE), T2-weighted imaging (T2WI) FSE, short tau inversion recovery (STIR), T2-weighted gradient recalled echo (GRE), pre-contrast fat-saturated T1WI, 3D post-contrast T1WI, diffusion-weighted imaging (DWI), and ANGIO TWIST (time-resolved angiography with interleaved stochastic trajectories) ISO. Results The study included 50 patients, with a male predominance of 28 (56%). The mean age was 22.13 years, and the average duration of vascular malformations was 32.94 months. The swelling was present in 43 (86%) of patients, and 35 (70%) had superficial lesions. MRI findings revealed hypointensity on T1 imaging in 40 (80%) patients and hyperintensity on T2 imaging in 49 (98%) cases. STIR sequences showed hyperintensity in all patients. The most common type of vascular malformation was slow-flow 46 (92%), with venous malformations being the most prevalent 39 (78%). Conclusion MRI is a valuable imaging modality for the evaluation and classification of vascular malformations, providing detailed information on lesion extent and involvement of surrounding tissues. The findings support the use of MRI as a primary tool in the assessment of vascular malformations, with ultrasound serving as a useful adjunct in certain cases. Further studies with larger sample sizes are recommended to validate these findings and refine imaging protocols.", - "journal": "Cureus", - "issn": [ - "2168-8184" - ], - "authors": [ - "Rajesh Kuber", - "Prajakta P KirdatPatil", - "Aryaman Dhande", - "Rahul Mane", - "Pushkar Kumar" - ], - "doi": "10.7759/cureus.67475", - "publishedDate": "2024-08-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39310382", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2312.11113v3", - "title": "An Interleaving Distance for Ordered Merge Trees", - "publishedDate": "2023-12-18T11:21:58", - "content": "Merge trees are a common topological descriptor for data with a hierarchical component, such as terrains and scalar fields. The interleaving distance, in turn, is a common distance measure for comparing merge trees. However, the interleaving distance for merge trees is solely based on the hierarchical structure, and disregards any other geometrical or topological properties that might be present in the underlying data. Furthermore, the interleaving distance is NP-hard to compute. In this paper, we introduce a form of ordered merge trees that does capture intrinsic order present in the data. We further define a natural variant of the interleaving distance, the monotone interleaving distance, which is an order preserving distance measure for ordered merge trees. Analogous to the regular interleaving distance for merge trees, we show that the monotone variant has three equivalent definitions in terms of two maps, a single map, or a labelling. The labelling-based definition fairly directly leads to an efficient algorithm for computing the monotone interleaving distance, but unfortunately it computes only an approximation thereof. Instead, we discover a surprising connection between the monotone interleaving distance of ordered merge trees and the Fr\\'{e}chet distance of 1D curves. As a result, the monotone interleaving distance between two ordered merge trees of total complexity $n$ can be computed exactly in $\\tilde O(n^2)$ time.

Across four sessions, 28 participants were trained on an artificial language, which included two types of morphologically complex words: linear (root + suffix) with a salient structure, and non-linear (root interleaved with template), with a prominent derivational structure in participants' first language (L1). A third simple monomorphemic condition, which served as baseline, was also included. On the first and fourth sessions, training was followed by testing in an fMRI scanner. Our behavioural results showed decomposition of both types of complex words, with the linear structure more easily learned than the non-linear structure. Our fMRI results showed involvement of frontal areas, associated with decomposition, only for the non-linear condition, after just the first session. We also observed training-related increases in activation in temporal areas specifically for the non-linear condition, which was correlated with participants' L1 morphological awareness. These results demonstrate that morphological decomposition of derived words occurs in the very early stages of word learning, is influenced by L1 experience, and can facilitate word learning. However, in contrast to the CLS framework, we found no support for a shift from reliance on hippocampus to reliance on cortical areas in any of our conditions.

HER4 (ErbB4) is the least studied member of this family, partly because its expression is lower in later stages of development. Recent work has suggested that HER4 can play a role in metastasis by regulating cell migration and invasiveness; however, unlike EGFR and HER2, the precise role that HER4 plays in tumorigenesis is still unresolved. Early work on HER family proteins suggested that there are direct interactions between the four members, but to date, there has been no single study of all four receptors in the same cell line with the same biophysical method. Here, we quantitatively measure the degree of association between HER4 and the other HER family proteins in live cells with a time-resolved fluorescence technique called pulsed interleaved excitation fluorescence cross-correlation spectroscopy (PIE-FCCS). PIE-FCCS is sensitive to the oligomerization state of membrane proteins in live cells, while simultaneously measuring single-cell protein expression levels and diffusion coefficients. Our PIE-FCCS results demonstrate that HER4 interacts directly with all HER family members in the cell plasma membrane.

In this paper we show how one can side-step this limitation by providing a general theory where one maps to a poset that does admit interesting translations, such as the lattice of down sets, and then defines interleavings relative to this map. Part of our theory includes a rigorous notion of discretization or \"pixelization\" of poset modules, which in turn we use for interleaving inference. We provide an approximation condition that in the setting of lattices gives rise to two possible pixelizations, both of which are guaranteed to be close in the interleaving distance.

Inspired by the interleaving learning technique of humans, in this paper we explore whether this learning methodology is beneficial for improving the performance of machine learning models as well. We propose a novel machine learning framework referred to as interleaving learning (IL). In our framework, a set of models collaboratively learn a data encoder in an interleaving fashion: the encoder is trained by model 1 for a while, then passed to model 2 for further training, then model 3, and so on; after trained by all models, the encoder returns back to model 1 and is trained again, then moving to model 2, 3, etc. This process repeats for multiple rounds. Our framework is based on multi-level optimization consisting of multiple inter-connected learning stages.

The main objective of this work is to contribute for a better understanding of the static behavior of structure made from fiber reinforced composite materials, specifically for the case of plate structures. The plate model is created using SOLIDWORKS 2017 and then imported into ANSYS R18.1. The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity. This suggests that the composite plate with a cross ply configuration is more suitable for manufacturing composite structures due to its improved performance.", - "journal": "Heliyon", - "issn": [ - "2405-8440" - ], - "authors": [ - "Chala Amsalu", - "Debela Negasa", - "Amanu Merga" - ], - "doi": "10.1016/j.heliyon.2024.e37698", - "publishedDate": "2024-09-09T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39328535", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 1 - ], - "score": 1.0, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39327664", - "title": "[Identification of conservation and restoration materials for iron relics through ultraviolet-induced visible luminescence imaging and pyrolysis-gas chromatography/mass spectrometry].", - "content": "Understanding the previous protection and restoration efforts and the current state of cultural relics is essential before compiling a conservation and restoration plan. The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics. This research provides valuable data for the restoration archives of five iron artifacts, offering a scientific basis for conservators to evaluate conservation methods, devise future conservation strategies, and exclude ineffective conservation materials.", - "journal": "Se pu = Chinese journal of chromatography", - "issn": [ - "1872-2059" - ], - "authors": [ - "Qin Yang", - "Li Ding", - "Zhao-Hui Li", - "Ran Zhang", - "Yue Wei", - "Ying Chen" - ], - "doi": "10.3724/SP.J.1123.2024.02005", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327664", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39327589", - "title": "Surface topography changes and wear resistance of different non-metallic telescopic crown attachment materials in implant retained overdenture (prospective comparative in vitro study).", - "content": "The purpose of this study was to evaluate the effect of using different types of metallic and non-metallic telescopic crown attachment materials on wear resistance and surface tomography changes in implant-retained mandibular overdentures.", - "journal": "BMC oral health", - "issn": [ - "1472-6831" - ], - "authors": [ - "Sherif M Abdel Hamid", - "Rim A Selima", - "Mohamed Z Basiony" - ], - "doi": "10.1186/s12903-024-04839-w", - "publishedDate": "2024-08-29T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327589", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39326167", - "title": "Unlocking epoxy thermal management capability via hierarchical Ce-MOF@MoS", - "content": "This study demonstrates the preparation of needle-like Ce-MOF crystals on molybdenum disulfide (MoS", - "journal": "Journal of colloid and interface science", - "issn": [ - "1095-7103" - ], - "authors": [ - "Xiaoli Yu", - "Pengfei Sun", - "Pengfei Jia", - "Wei Wang", - "Kang Dai", - "Bibo Wang", - "Lei Song" - ], - "doi": "10.1016/j.jcis.2024.09.176", - "publishedDate": "2024-09-19T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39326167", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39326165", - "title": "Rational design of epoxy functionalized ionic liquids electrolyte additive for hydrogen-free and dendrite-free aqueous zinc batteries.", - "content": "Despite the high safety and low cost associated with aqueous Zn-ion batteries (ZIBs), uncontrolled Zn dendrite growth and parasitic reactions induced by water significantly diminish their stability.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen. It was evident that the modulus of elasticity property of short fiber composites exhibits an increasing trend with higher fiber content, even at 35 wt%. Moreover, the enhancement of tensile strength for the short fiber size composites reached 72.5 %. However, such tensile strength of thin fiber size/epoxy composites achieved 135.7 % at 25 wt% indicating superior development of this mechanical property.

The porous carbon material was made from the byproduct of cellulose production and was used as additive on the development of radar absorbing material (RAM) composites. These porous carbon materials have different characteristics, such as porosity size (180 µm < Ø1 < 250 µm and 425 µm < Ø2 < 500 µm) and particle size (ϕ1 < 250 µm and 250 µm < ϕ2 < 425 µm). Composite materials were also studied as frequency selective surface (FSS) structures.

The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics. This research provides valuable data for the restoration archives of five iron artifacts, offering a scientific basis for conservators to evaluate conservation methods, devise future conservation strategies, and exclude ineffective conservation materials.", - "journal": "Se pu = Chinese journal of chromatography", - "issn": [ - "1872-2059" - ], - "authors": [ - "Qin Yang", - "Li Ding", - "Zhao-Hui Li", - "Ran Zhang", - "Yue Wei", - "Ying Chen" - ], - "doi": "10.3724/SP.J.1123.2024.02005", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327664", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39327589", - "title": "Surface topography changes and wear resistance of different non-metallic telescopic crown attachment materials in implant retained overdenture (prospective comparative in vitro study).", - "content": "The purpose of this study was to evaluate the effect of using different types of metallic and non-metallic telescopic crown attachment materials on wear resistance and surface tomography changes in implant-retained mandibular overdentures.", - "journal": "BMC oral health", - "issn": [ - "1472-6831" - ], - "authors": [ - "Sherif M Abdel Hamid", - "Rim A Selima", - "Mohamed Z Basiony" - ], - "doi": "10.1186/s12903-024-04839-w", - "publishedDate": "2024-08-29T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327589", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39326167", - "title": "Unlocking epoxy thermal management capability via hierarchical Ce-MOF@MoS", - "content": "This study demonstrates the preparation of needle-like Ce-MOF crystals on molybdenum disulfide (MoS", - "journal": "Journal of colloid and interface science", - "issn": [ - "1095-7103" - ], - "authors": [ - "Xiaoli Yu", - "Pengfei Sun", - "Pengfei Jia", - "Wei Wang", - "Kang Dai", - "Bibo Wang", - "Lei Song" - ], - "doi": "10.1016/j.jcis.2024.09.176", - "publishedDate": "2024-09-19T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39326167", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39326165", - "title": "Rational design of epoxy functionalized ionic liquids electrolyte additive for hydrogen-free and dendrite-free aqueous zinc batteries.", - "content": "Despite the high safety and low cost associated with aqueous Zn-ion batteries (ZIBs), uncontrolled Zn dendrite growth and parasitic reactions induced by water significantly diminish their stability.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen.

The anti-hyperglycemic effects of the FOD extract and the pure compounds were studied in mice using the Oral Glucose Tolerance Test (OGTT) and streptozotocin (STZ)-induced diabetes mellitus (DM) models. Molecular docking studies were performed on potent compounds in the binding pockets of enzymes α-glucosidase and α-amylase. The isolations of 11 compounds were isolated from the FOD extract, which comprised teferidine (1), ferutinin (FT) (2), teferin (3), epoxy-jaeschkeanadiol-p-hydroxybenzoate (4), epoxy-jaeschkeanadiol-6-vanillate (5), tovarol-8-angelate (6), leucoferin (7), tovarol-8-p-hydroxybenzoate (8), tovarol-8-vanillate (9), 6-β-p-hydroxybenzoyloxy-germacra-1(10),4-diene (10), and chimgin (11). Compounds 2 and 8-11 exhibited a higher inhibitory activity on α-glucosidase. In the OGTT, pretreatment with the FOD extract or compound 2 did not alter the BGLs after administration of the glucose solution compared to the control. In the STZ-induced diabetic mice model, no significant difference in the BGLs was observed with the FOD extract (200 mg/kg) or compound 2 (100 mg/kg)-treated diabetic mice compared to the diabetic control mice.

COC films were produced by hot pressing and were interleaved in the interlaminar regions between each EP/CF lamina, during the hand layup fabrication of the laminates. Three samples were produced, i.e., the neat EP/CF laminate without COC, and two laminates containing COC layers with a thickness of 44 μm and 77 μm, respectively. It was observed that the fiber volume fraction decreased, and the porosity increased with the introduction of COC layers, and this effect was more evident when thick films were used. These two effects, combined with the sub-optimal adhesion between COC and EP, caused a decrease in the mechanical properties (i.e., the elastic modulus, flexural strength, interlaminar shear strength and interlaminar fracture toughness) of the laminates. Specimens subjected to mode I interlaminar fracture toughness test were then thermally mended under pressure by resistive heating, through the Joule effect of conductive CFs. A temperature of approximately 190 °C was reached during the healing treatment. The healing efficiency was evaluated as the ratio of critical strain energy release rate (GIC) of the healed and virgin specimens. Healed specimens containing COC layers of 44 μm and 77 μm exhibited a healing efficiency of 164% and 100%, respectively. As expected, the healing treatment was not beneficial for the neat EP/CF laminate without COC, which experienced a healing efficiency of only 2%.

The aim of this study is to visualize and quantify the ghost spectral lines produced by two, three and four interleaved echo trains with different amplitudes of the readout gradients, and to investigate the feasibility of the flyback data acquisition in micro-imaging of small animals. Applied multi-slice EPSI sequence utilizes asymmetric gradient-echo train that combines the shortest possible rewind gradients with readout gradients. It simplifies data processing because all echoes are acquired with the same polarity of the readout gradient. The approach with four interleaved gradient-echo trains and with four echoes in each train provides broad spectral bandwidth in combination with narrow receiver bandwidth and a good water-fat signal separation. It improves signal-to-noise ratio without the undesired consequence of water-fat shift artifacts that are eliminated during data processing. Position, number, and intensity of the ghost spectral lines can be controlled by the suitable choice of spectral bandwidth, number of echo train interleaves, and the number of echoes in each interleave.

The strong echogenicity of accumulated MBs also improves diagnostics via conventional ultrasound (US) B-mode imaging. However, the annular high-pressure distribution of AVT inhibits MBs inflow at the inlet, reducing MBs collection. The spatial resolution of US B-mode imaging further limits theranostic applications of AVT-mediated MBs accumulation. To address these challenges, we integrated an AVT waveform with volumetric super-resolution imaging (VSRI) to monitor the dynamic growth of MBs cluster during accumulation. We used a 5-MHz 2D array transducer for VSRI, employing plane wave pulses interleaved with accumulating pulses to retain MBs at a flow rate of 0.023-0.047 mL/s in a 3-mm vessel phantom. An asymmetrical AVT waveform (AVT*) was produced by modulating the pressure at the MBs inlet compared to the outlet. The effectiveness was validated in rat cerebral vessels for real-time volumetric tracking of MBs clusters. Microscopy observations showed that AVT* could quickly gather flowing MBs into cluster without repelling them at a flow rate of 0.023 mL/s. Statistical results indicated that microscopic data correlated better with VSRI than with B-mode images, suggesting VSRI suffices to detect the dynamics of AVT*-actuated MBs accumulation in real-time. Additionally, VSRI detected a significant increase in MBs cluster size over time during AVT* in the superior sagittal sinus of the rat brain. These findings demonstrate that the proposed strategy can accumulate the flowing MBs at a desired location and simultaneously observe this phenomenon.", - "journal": "IEEE transactions on ultrasonics, ferroelectrics, and frequency control", - "issn": [ - "1525-8955" - ], - "authors": [ - "Ching-Hsiang Fan", - "Wei-Chen Lo", - "Chung-Han Huang", - "Thi-Nhan Phan", - "Chih-Kuang Yeh" - ], - "doi": "10.1109/TUFFC.2024.3466119", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39312432", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39310382", - "title": "Magnetic Resonance Imaging (MRI) Evaluation and Classification of Vascular Malformations.", - "content": "Introduction Vascular malformations of the soft tissues are a diverse collection of lesions frequently encountered in clinical practice. Vascular malformations are rare and complex abnormalities that affect both children and young adults. Low-flow malformations are more common in children and often become symptomatic in later years. These malformations are common causes of soft tissue masses in children and can affect any part of the body at any age. Significant advancements in the management of these conditions have been made due to the implementation of a comprehensive binary categorization system, which classifies vascular abnormalities into tumors and malformations based on their clinicopathological characteristics. Imaging, particularly magnetic resonance imaging (MRI), plays a crucial role in the accurate identification, localization, and classification of these lesions, aiding in the development of appropriate treatment plans. Materials and methods This prospective study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune, from August 2022 to June 2024. Fifty patients of all age groups with clinically suspected soft tissue vascular malformations were included. MRI was performed using a MAGNETOM Vida (3T) Scanner (Siemens Healthcare Private Limited, Mumbai, India), and ultrasound was used as an adjunct. Institutional Ethics Committee clearance and informed consent were obtained. The study employed various MRI sequences, including T1-weighted imaging (T1WI) fast spin echo (FSE), T2-weighted imaging (T2WI) FSE, short tau inversion recovery (STIR), T2-weighted gradient recalled echo (GRE), pre-contrast fat-saturated T1WI, 3D post-contrast T1WI, diffusion-weighted imaging (DWI), and ANGIO TWIST (time-resolved angiography with interleaved stochastic trajectories) ISO. Results The study included 50 patients, with a male predominance of 28 (56%). The mean age was 22.13 years, and the average duration of vascular malformations was 32.94 months. The swelling was present in 43 (86%) of patients, and 35 (70%) had superficial lesions. MRI findings revealed hypointensity on T1 imaging in 40 (80%) patients and hyperintensity on T2 imaging in 49 (98%) cases. STIR sequences showed hyperintensity in all patients. The most common type of vascular malformation was slow-flow 46 (92%), with venous malformations being the most prevalent 39 (78%). Conclusion MRI is a valuable imaging modality for the evaluation and classification of vascular malformations, providing detailed information on lesion extent and involvement of surrounding tissues. The findings support the use of MRI as a primary tool in the assessment of vascular malformations, with ultrasound serving as a useful adjunct in certain cases. Further studies with larger sample sizes are recommended to validate these findings and refine imaging protocols.", - "journal": "Cureus", - "issn": [ - "2168-8184" - ], - "authors": [ - "Rajesh Kuber", - "Prajakta P KirdatPatil", - "Aryaman Dhande", - "Rahul Mane", - "Pushkar Kumar" - ], - "doi": "10.7759/cureus.67475", - "publishedDate": "2024-08-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39310382", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39301207", - "title": "Neural Mechanisms of Learning and Consolidation of Morphologically Derived Words in a Novel Language: Evidence From Hebrew Speakers.", - "content": "We examined neural mechanisms associated with the learning of novel morphologically derived words in native Hebrew speakers within the Complementary Learning Systems (CLS) framework. Across four sessions, 28 participants were trained on an artificial language, which included two types of morphologically complex words: linear (root + suffix) with a salient structure, and non-linear (root interleaved with template), with a prominent derivational structure in participants' first language (L1). A third simple monomorphemic condition, which served as baseline, was also included. On the first and fourth sessions, training was followed by testing in an fMRI scanner. Our behavioural results showed decomposition of both types of complex words, with the linear structure more easily learned than the non-linear structure. Our fMRI results showed involvement of frontal areas, associated with decomposition, only for the non-linear condition, after just the first session. We also observed training-related increases in activation in temporal areas specifically for the non-linear condition, which was correlated with participants' L1 morphological awareness. These results demonstrate that morphological decomposition of derived words occurs in the very early stages of word learning, is influenced by L1 experience, and can facilitate word learning. However, in contrast to the CLS framework, we found no support for a shift from reliance on hippocampus to reliance on cortical areas in any of our conditions. Instead, our findings align more closely with recent theories showing a positive correlation between changes in hippocampus and cortical areas, suggesting that these representations co-exist and continue to interact with one another beyond initial learning.", - "journal": "Neurobiology of language (Cambridge, Mass.)", - "issn": [ - "2641-4368" - ], - "authors": [ - "Upasana Nathaniel", - "Stav Eidelsztein", - "Kate Girsh Geskin", - "Brianna L Yamasaki", - "Bracha Nir", - "Vedran Dronjic", - "James R Booth", - "Tali Bitan" - ], - "doi": "10.1162/nol_a_00150", - "publishedDate": "2024-06-07T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39301207", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39276020", - "title": "HER4 is a high-affinity dimerization partner for all EGFR/HER/ErbB family proteins.", - "content": "Human epidermal growth factor receptors (HER)-also known as EGFR or ErbB receptors-are a subfamily of receptor tyrosine kinases (RTKs) that play crucial roles in cell growth, division, and differentiation. HER4 (ErbB4) is the least studied member of this family, partly because its expression is lower in later stages of development. Recent work has suggested that HER4 can play a role in metastasis by regulating cell migration and invasiveness; however, unlike EGFR and HER2, the precise role that HER4 plays in tumorigenesis is still unresolved. Early work on HER family proteins suggested that there are direct interactions between the four members, but to date, there has been no single study of all four receptors in the same cell line with the same biophysical method. Here, we quantitatively measure the degree of association between HER4 and the other HER family proteins in live cells with a time-resolved fluorescence technique called pulsed interleaved excitation fluorescence cross-correlation spectroscopy (PIE-FCCS). PIE-FCCS is sensitive to the oligomerization state of membrane proteins in live cells, while simultaneously measuring single-cell protein expression levels and diffusion coefficients. Our PIE-FCCS results demonstrate that HER4 interacts directly with all HER family members in the cell plasma membrane. The interaction between HER4 and other HER family members intensified in the presence of a HER4-specific ligand.

In this work we contribute a polarization insensitive frequency multiplexed 2-bit coding metasurface to control the Terahertz (THz) waves in the two operating bands independently. In this regard, as a first step a cascaded meta-atom composed of square rings and/or square metallic patches separated by two polyimide substrates is designed and optimized that provides sixteen independent distinct discrete phases in the reflection geometry. These meta-atoms are then distributed with distinct coding sequences in the two-dimensional spatial plane to realize various bi-functional metasurfaces. As a proof of the concept various full structures are designed and simulated to realize a series of bi-functionalities including anomalous reflection/beam shaping, beam shaping/anomalous reflection, beam deflection/Orbital angular momentum (OAM) beam generation with distinct modes and propagating wave to surface wave (PW-SW) conversion/PW beam manipulation in the lower and higher THz bands, respectively. All the simulation results are in excellent agreement with their theoretical equivalents. We envision that the proposed meta-designs have potential applications for the multi-spectral control of EM waves in THz band.

How are these schemas acquired? A key challenge is that learning a new schema can catastrophically interfere with old knowledge. One solution to this dilemma is to use interleaved training to learn a single representation that accommodates all schemas. However, another class of models posits that catastrophic interference can be avoided by splitting off new representations when large prediction errors occur. A key differentiating prediction is that, according to splitting models, catastrophic interference can be prevented even under blocked training curricula. We conducted a series of semi-naturalistic experiments and simulations with Bayesian and neural network models to compare the predictions made by the \"splitting\" versus \"non-splitting\" hypotheses of schema learning. We found better performance in blocked compared to interleaved curricula, and explain these results using a Bayesian model that incorporates representational splitting in response to large prediction errors. In a follow-up experiment, we validated the model prediction that inserting blocked training early in learning leads to better learning performance than inserting blocked training later in learning.

The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics. This research provides valuable data for the restoration archives of five iron artifacts, offering a scientific basis for conservators to evaluate conservation methods, devise future conservation strategies, and exclude ineffective conservation materials.", - "journal": "Se pu = Chinese journal of chromatography", - "issn": [ - "1872-2059" - ], - "authors": [ - "Qin Yang", - "Li Ding", - "Zhao-Hui Li", - "Ran Zhang", - "Yue Wei", - "Ying Chen" - ], - "doi": "10.3724/SP.J.1123.2024.02005", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327664", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39327589", - "title": "Surface topography changes and wear resistance of different non-metallic telescopic crown attachment materials in implant retained overdenture (prospective comparative in vitro study).", - "content": "The purpose of this study was to evaluate the effect of using different types of metallic and non-metallic telescopic crown attachment materials on wear resistance and surface tomography changes in implant-retained mandibular overdentures.", - "journal": "BMC oral health", - "issn": [ - "1472-6831" - ], - "authors": [ - "Sherif M Abdel Hamid", - "Rim A Selima", - "Mohamed Z Basiony" - ], - "doi": "10.1186/s12903-024-04839-w", - "publishedDate": "2024-08-29T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327589", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39326167", - "title": "Unlocking epoxy thermal management capability via hierarchical Ce-MOF@MoS", - "content": "This study demonstrates the preparation of needle-like Ce-MOF crystals on molybdenum disulfide (MoS", - "journal": "Journal of colloid and interface science", - "issn": [ - "1095-7103" - ], - "authors": [ - "Xiaoli Yu", - "Pengfei Sun", - "Pengfei Jia", - "Wei Wang", - "Kang Dai", - "Bibo Wang", - "Lei Song" - ], - "doi": "10.1016/j.jcis.2024.09.176", - "publishedDate": "2024-09-19T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39326167", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39326165", - "title": "Rational design of epoxy functionalized ionic liquids electrolyte additive for hydrogen-free and dendrite-free aqueous zinc batteries.", - "content": "Despite the high safety and low cost associated with aqueous Zn-ion batteries (ZIBs), uncontrolled Zn dendrite growth and parasitic reactions induced by water significantly diminish their stability.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen. It was evident that the modulus of elasticity property of short fiber composites exhibits an increasing trend with higher fiber content, even at 35 wt%. Moreover, the enhancement of tensile strength for the short fiber size composites reached 72.5 %. However, such tensile strength of thin fiber size/epoxy composites achieved 135.7 % at 25 wt% indicating superior development of this mechanical property.

Using the theoretical framework of non-affine lattice dynamics (NALD), based on the instantaneous normal modes analysis determined through the dynamical matrix of the system, we study the viscoelastic response of a cross-linked epoxy system of diglycidyl ether of bisphenol A (DGEBA) and poly(oxypropylene) diamine, over many orders of magnitude in deformation frequency, below the glass transition temperature. Predictions of the elastic modulus are satisfactorily validated against the non-equilibrium molecular dynamics simulations in the high-frequency regime, and against experimental data from dynamic mechanical analysis at frequencies $ \\sim 1 {\\rm Hz}$, hence successfully bridging the timescale gap. The comparison shows that non-affine displacements at the atomic level account for nearly two orders of magnitude reduction in the low-frequency elastic modulus of the polymer glass, compared to affine elasticity estimates.

Hence, in order to experiment with more design parameters, robust and easy computational techniques need to be established. To this end, we developed and analyzed in this study a new machine learning (ML) based approach to predict the mechanical properties of epoxy polymers based on their basic structural features. The results from molecular dynamics (MD) simulations have been used to derive the ML model. The salient feature of our work is that for the development of epoxy polymers based on EPON-862, several new hardeners were explored in addition to the conventionally used ones. The influence of additional parameters like the proportion of curing agent used and the extent of curing on the mechanical properties of epoxy polymers were also investigated.

They are produced by integrating thin sandwich structures of CNT fiber veils and an ionic liquid-based polymer electrolyte between carbon fiber plies, followed by infusion and curing of an epoxy resin. The resulting structure behaves simultaneously as an electric double-layer capacitor and a structural composite, with flexural modulus of 60 GPa and flexural strength of 153 MPa, combined with 88 mF/g of specific capacitance and the highest power (30 W/kg) and energy (37.5 mWh/kg) densities reported so far for structural supercapacitors. In-situ electrochemical measurements during 4-point bending show that electrochemical performance is retained up to fracture, with minor changes in equivalent series resistance for interleaves under compressive stress. En route to improving interlaminar properties we produce grid-shaped interleaves that enable mechanical interconnection of plies by the stiff epoxy. Synchrotron 3D X-ray tomography analysis of the resulting hierarchical structure confirms the formation of interlaminar epoxy joints. The manuscript discusses encapsulation role of epoxy, demonstrated by charge-discharge measurements of composites immersed in water, a deleterious agent for ionic liquids. Finally, we show different architectures free of current collector and electrical insulators, in which both CNT fiber and CF act as active electrodes.", - "doi": "10.1038/s41598-018-21829-5", - "authors": [ - "Evgeny Senokos", - "Yunfu Ou", - "Juan Jose Torres", - "Federico Sket", - "Carlos Gonzalez", - "Rebeca Marcilla", - "Juan J.

The main objective of this work is to contribute for a better understanding of the static behavior of structure made from fiber reinforced composite materials, specifically for the case of plate structures. The plate model is created using SOLIDWORKS 2017 and then imported into ANSYS R18.1. The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity. This suggests that the composite plate with a cross ply configuration is more suitable for manufacturing composite structures due to its improved performance.", - "journal": "Heliyon", - "issn": [ - "2405-8440" - ], - "authors": [ - "Chala Amsalu", - "Debela Negasa", - "Amanu Merga" - ], - "doi": "10.1016/j.heliyon.2024.e37698", - "publishedDate": "2024-09-09T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39328535", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 1 - ], - "score": 1.0, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1905.09080v2", - "title": "Interlaminar toughening in structural carbon fiber/epoxy composites interleaved with carbon nanotube veils", - "publishedDate": "2019-05-22T11:34:19", - "content": "The susceptibility to delamination is one of the main concerns in fiber reinforced polymer composites (FRPs). This work demonstrates improvements of 60% in Mode-I fracture toughness after integration of thin (~30 micron), continuous veils of carbon nanotubes (CNTs) directly deposited onto carbon fiber fabric as the CNT are drawn from the gas-phase using a semi-industrial process. A combination of optical imaging, scanning electron microscopy and a Raman spectroscopy provide a new rapid tool to unambiguously determine the crack propagation path by simple visual inspection of fracture surface. The results show that interlaminar crossing between CNT veil/CF interfaces is of paramount importance. The crack front alternatingly propagates above and below the CNT-toughened interlayer, significantly improving the fracture toughness of resultant laminates. This mechanism is strongly influenced by the method used to integrate the veils onto the CF.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics. This research provides valuable data for the restoration archives of five iron artifacts, offering a scientific basis for conservators to evaluate conservation methods, devise future conservation strategies, and exclude ineffective conservation materials.", - "journal": "Se pu = Chinese journal of chromatography", - "issn": [ - "1872-2059" - ], - "authors": [ - "Qin Yang", - "Li Ding", - "Zhao-Hui Li", - "Ran Zhang", - "Yue Wei", - "Ying Chen" - ], - "doi": "10.3724/SP.J.1123.2024.02005", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327664", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1905.08422v1", - "title": "The mechanical and electrical properties of direct-spun carbon nanotube mat-epoxy composites", - "publishedDate": "2019-05-21T03:17:43", - "content": "Composites of direct-spun carbon nanotube (CNT) mats and epoxy are manufactured and tested in order to determine their mechanical and electrical properties.

Subsequent evaporation of the acetone, followed by a cure cycle, leads to composites of varying volume fraction of CNT, epoxy and air. The modulus, strength, electrical conductivity and piezoresistivity of the composites are measured. The CNT mats and their composites exhibit an elastic-plastic stress-strain response under uniaxial tensile loading, and the degree of anisotropy is assessed by testing specimens in 0{\\deg}, 45{\\deg} and 90{\\deg} directions with respect to the draw direction of mat manufacture. The electrical conductivity scales linearly with CNT volume fraction, irrespective of epoxy volume fraction. In contrast, the modulus and strength depend upon both CNT and epoxy volume fractions in a non-linear manner.

The properties and performance of epoxy polymers depend upon various factors like the type of constituents and their proportions used and other process parameters. The conventional way of developing epoxy polymers is usually labor-intensive and may not be fully efficient, which has resulted in epoxy polymers having a limited performance range due to the use of predetermined blend combinations, compositions and development parameters. Hence, in order to experiment with more design parameters, robust and easy computational techniques need to be established. To this end, we developed and analyzed in this study a new machine learning (ML) based approach to predict the mechanical properties of epoxy polymers based on their basic structural features. The results from molecular dynamics (MD) simulations have been used to derive the ML model. The salient feature of our work is that for the development of epoxy polymers based on EPON-862, several new hardeners were explored in addition to the conventionally used ones. The influence of additional parameters like the proportion of curing agent used and the extent of curing on the mechanical properties of epoxy polymers were also investigated.

While role of solvents in enabling superior mechanical properties has been addressed before, outlined study is the first to address the effect of solvents on thermal conductivity enhancement and provides novel pathways for achieving high thermal conductivity polymer composite materials. Uniform dispersion of graphene nanoparticles into epoxy can improve thermal contact with polymer leading to superior interface thermal conductance between polymer matrix and graphene. Organic solvents are typically employed to achieve efficient dispersion of graphene into the epoxy matrix. In this study, we compare the effect of two organic solvents, dimethylformamide (DMF) and acetone, in terms of their efficiency in dispersing graphene into the epoxy matrix and their effect on enhancing thermal conductivity of the composite. We find that polymer-graphene composites made with DMF solvent show 44% higher thermal conductivity compared to those made using acetone at 7 weight% filler composition. Laser scanning confocal microscopy (LSCM) imaging reveals that graphene-epoxy composites, prepared using DMF as solvent, exhibit more uniform dispersion of graphene-nanoplatelets compared to the case of acetone with acetone-based samples exhibiting up to 211% larger graphene agglomerations. Comparison with effective medium theory reveals an almost 35% lower interface thermal resistance between graphene and epoxy for DMF relative to acetone prepared composite.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen. It was evident that the modulus of elasticity property of short fiber composites exhibits an increasing trend with higher fiber content, even at 35 wt%. Moreover, the enhancement of tensile strength for the short fiber size composites reached 72.5 %. However, such tensile strength of thin fiber size/epoxy composites achieved 135.7 % at 25 wt% indicating superior development of this mechanical property.

The processing of fiber-reinforced epoxy composite structures requires carefully selected heating and cooling cycles to fully cure the resin and form strong crosslinked networks. To fully optimize the processing parameters for effective epoxy monomer crosslinking and final product integrity, the evolution of mechanical properties of epoxies during processing must be comprehensively understood. Because the full experimental characterization of these properties as a function of the degree of cure is difficult and time-consuming, efficient computational predictive tools are needed. The objective of this research is to develop an experimentally validated Molecular Dynamics (MD) modeling method, which incorporates a reactive force field, to accurately predict the thermo-mechanical properties of an epoxy resin as a function of the degree of cure. Experimental rheometric and mechanical testing are used to validate an MD model which is subsequently used to predict mass density, shrinkage, elastic properties, and yield strength as a function of the degree of cure.

This problem relates to oscillating blood flow in viscoelastic vessels. The deeper motivation for this study, however, is the possible use of compliant coatings for turbulent drag reduction. An analytical solution of the fluid and solid velocity is presented, and five dimensionless parameters emerge. The interaction between fluid and solid appears to be determined by a single combined dimensionless parameter, which we call the shear interaction parameter $\\chi$. The fluid satisfies a no-slip boundary condition when $\\left|\\chi\\right| \\rightarrow 0$, which occurs when the solid is heavy, stiff and/or thin. In contrast, the fluid obeys a free-slip boundary condition when $\\left|\\chi\\right| \\rightarrow \\infty$, which corresponds to a lightweight and/or soft solid. Three types of resonance modes are identified for an elastic solid. Two modes (odd and even) are specific to the solid. The third mode results from the coupling with the fluid. The three modes are less pronounced or even absent for a viscoelastic solid. These findings have a twofold use. First, they help to understand the fluid and solid dynamics when shear coupling is important. Second, the presented analytical solution is very useful for validation of numerical fluid-structure-interaction solvers.

The aim of this study is to visualize and quantify the ghost spectral lines produced by two, three and four interleaved echo trains with different amplitudes of the readout gradients, and to investigate the feasibility of the flyback data acquisition in micro-imaging of small animals. Applied multi-slice EPSI sequence utilizes asymmetric gradient-echo train that combines the shortest possible rewind gradients with readout gradients. It simplifies data processing because all echoes are acquired with the same polarity of the readout gradient. The approach with four interleaved gradient-echo trains and with four echoes in each train provides broad spectral bandwidth in combination with narrow receiver bandwidth and a good water-fat signal separation. It improves signal-to-noise ratio without the undesired consequence of water-fat shift artifacts that are eliminated during data processing. Position, number, and intensity of the ghost spectral lines can be controlled by the suitable choice of spectral bandwidth, number of echo train interleaves, and the number of echoes in each interleave.

The strong echogenicity of accumulated MBs also improves diagnostics via conventional ultrasound (US) B-mode imaging. However, the annular high-pressure distribution of AVT inhibits MBs inflow at the inlet, reducing MBs collection. The spatial resolution of US B-mode imaging further limits theranostic applications of AVT-mediated MBs accumulation. To address these challenges, we integrated an AVT waveform with volumetric super-resolution imaging (VSRI) to monitor the dynamic growth of MBs cluster during accumulation. We used a 5-MHz 2D array transducer for VSRI, employing plane wave pulses interleaved with accumulating pulses to retain MBs at a flow rate of 0.023-0.047 mL/s in a 3-mm vessel phantom. An asymmetrical AVT waveform (AVT*) was produced by modulating the pressure at the MBs inlet compared to the outlet. The effectiveness was validated in rat cerebral vessels for real-time volumetric tracking of MBs clusters. Microscopy observations showed that AVT* could quickly gather flowing MBs into cluster without repelling them at a flow rate of 0.023 mL/s. Statistical results indicated that microscopic data correlated better with VSRI than with B-mode images, suggesting VSRI suffices to detect the dynamics of AVT*-actuated MBs accumulation in real-time. Additionally, VSRI detected a significant increase in MBs cluster size over time during AVT* in the superior sagittal sinus of the rat brain. These findings demonstrate that the proposed strategy can accumulate the flowing MBs at a desired location and simultaneously observe this phenomenon.", - "journal": "IEEE transactions on ultrasonics, ferroelectrics, and frequency control", - "issn": [ - "1525-8955" - ], - "authors": [ - "Ching-Hsiang Fan", - "Wei-Chen Lo", - "Chung-Han Huang", - "Thi-Nhan Phan", - "Chih-Kuang Yeh" - ], - "doi": "10.1109/TUFFC.2024.3466119", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39312432", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39310382", - "title": "Magnetic Resonance Imaging (MRI) Evaluation and Classification of Vascular Malformations.", - "content": "Introduction Vascular malformations of the soft tissues are a diverse collection of lesions frequently encountered in clinical practice. Vascular malformations are rare and complex abnormalities that affect both children and young adults. Low-flow malformations are more common in children and often become symptomatic in later years. These malformations are common causes of soft tissue masses in children and can affect any part of the body at any age. Significant advancements in the management of these conditions have been made due to the implementation of a comprehensive binary categorization system, which classifies vascular abnormalities into tumors and malformations based on their clinicopathological characteristics. Imaging, particularly magnetic resonance imaging (MRI), plays a crucial role in the accurate identification, localization, and classification of these lesions, aiding in the development of appropriate treatment plans. Materials and methods This prospective study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune, from August 2022 to June 2024. Fifty patients of all age groups with clinically suspected soft tissue vascular malformations were included. MRI was performed using a MAGNETOM Vida (3T) Scanner (Siemens Healthcare Private Limited, Mumbai, India), and ultrasound was used as an adjunct. Institutional Ethics Committee clearance and informed consent were obtained. The study employed various MRI sequences, including T1-weighted imaging (T1WI) fast spin echo (FSE), T2-weighted imaging (T2WI) FSE, short tau inversion recovery (STIR), T2-weighted gradient recalled echo (GRE), pre-contrast fat-saturated T1WI, 3D post-contrast T1WI, diffusion-weighted imaging (DWI), and ANGIO TWIST (time-resolved angiography with interleaved stochastic trajectories) ISO. Results The study included 50 patients, with a male predominance of 28 (56%). The mean age was 22.13 years, and the average duration of vascular malformations was 32.94 months. The swelling was present in 43 (86%) of patients, and 35 (70%) had superficial lesions. MRI findings revealed hypointensity on T1 imaging in 40 (80%) patients and hyperintensity on T2 imaging in 49 (98%) cases. STIR sequences showed hyperintensity in all patients. The most common type of vascular malformation was slow-flow 46 (92%), with venous malformations being the most prevalent 39 (78%). Conclusion MRI is a valuable imaging modality for the evaluation and classification of vascular malformations, providing detailed information on lesion extent and involvement of surrounding tissues. The findings support the use of MRI as a primary tool in the assessment of vascular malformations, with ultrasound serving as a useful adjunct in certain cases. Further studies with larger sample sizes are recommended to validate these findings and refine imaging protocols.", - "journal": "Cureus", - "issn": [ - "2168-8184" - ], - "authors": [ - "Rajesh Kuber", - "Prajakta P KirdatPatil", - "Aryaman Dhande", - "Rahul Mane", - "Pushkar Kumar" - ], - "doi": "10.7759/cureus.67475", - "publishedDate": "2024-08-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39310382", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39301207", - "title": "Neural Mechanisms of Learning and Consolidation of Morphologically Derived Words in a Novel Language: Evidence From Hebrew Speakers.", - "content": "We examined neural mechanisms associated with the learning of novel morphologically derived words in native Hebrew speakers within the Complementary Learning Systems (CLS) framework. Across four sessions, 28 participants were trained on an artificial language, which included two types of morphologically complex words: linear (root + suffix) with a salient structure, and non-linear (root interleaved with template), with a prominent derivational structure in participants' first language (L1). A third simple monomorphemic condition, which served as baseline, was also included. On the first and fourth sessions, training was followed by testing in an fMRI scanner. Our behavioural results showed decomposition of both types of complex words, with the linear structure more easily learned than the non-linear structure. Our fMRI results showed involvement of frontal areas, associated with decomposition, only for the non-linear condition, after just the first session. We also observed training-related increases in activation in temporal areas specifically for the non-linear condition, which was correlated with participants' L1 morphological awareness. These results demonstrate that morphological decomposition of derived words occurs in the very early stages of word learning, is influenced by L1 experience, and can facilitate word learning. However, in contrast to the CLS framework, we found no support for a shift from reliance on hippocampus to reliance on cortical areas in any of our conditions. Instead, our findings align more closely with recent theories showing a positive correlation between changes in hippocampus and cortical areas, suggesting that these representations co-exist and continue to interact with one another beyond initial learning.", - "journal": "Neurobiology of language (Cambridge, Mass.)", - "issn": [ - "2641-4368" - ], - "authors": [ - "Upasana Nathaniel", - "Stav Eidelsztein", - "Kate Girsh Geskin", - "Brianna L Yamasaki", - "Bracha Nir", - "Vedran Dronjic", - "James R Booth", - "Tali Bitan" - ], - "doi": "10.1162/nol_a_00150", - "publishedDate": "2024-06-07T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39301207", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39276020", - "title": "HER4 is a high-affinity dimerization partner for all EGFR/HER/ErbB family proteins.", - "content": "Human epidermal growth factor receptors (HER)-also known as EGFR or ErbB receptors-are a subfamily of receptor tyrosine kinases (RTKs) that play crucial roles in cell growth, division, and differentiation. HER4 (ErbB4) is the least studied member of this family, partly because its expression is lower in later stages of development. Recent work has suggested that HER4 can play a role in metastasis by regulating cell migration and invasiveness; however, unlike EGFR and HER2, the precise role that HER4 plays in tumorigenesis is still unresolved. Early work on HER family proteins suggested that there are direct interactions between the four members, but to date, there has been no single study of all four receptors in the same cell line with the same biophysical method. Here, we quantitatively measure the degree of association between HER4 and the other HER family proteins in live cells with a time-resolved fluorescence technique called pulsed interleaved excitation fluorescence cross-correlation spectroscopy (PIE-FCCS). PIE-FCCS is sensitive to the oligomerization state of membrane proteins in live cells, while simultaneously measuring single-cell protein expression levels and diffusion coefficients. Our PIE-FCCS results demonstrate that HER4 interacts directly with all HER family members in the cell plasma membrane. The interaction between HER4 and other HER family members intensified in the presence of a HER4-specific ligand.

In this work we contribute a polarization insensitive frequency multiplexed 2-bit coding metasurface to control the Terahertz (THz) waves in the two operating bands independently. In this regard, as a first step a cascaded meta-atom composed of square rings and/or square metallic patches separated by two polyimide substrates is designed and optimized that provides sixteen independent distinct discrete phases in the reflection geometry. These meta-atoms are then distributed with distinct coding sequences in the two-dimensional spatial plane to realize various bi-functional metasurfaces. As a proof of the concept various full structures are designed and simulated to realize a series of bi-functionalities including anomalous reflection/beam shaping, beam shaping/anomalous reflection, beam deflection/Orbital angular momentum (OAM) beam generation with distinct modes and propagating wave to surface wave (PW-SW) conversion/PW beam manipulation in the lower and higher THz bands, respectively. All the simulation results are in excellent agreement with their theoretical equivalents.

How are these schemas acquired? A key challenge is that learning a new schema can catastrophically interfere with old knowledge. One solution to this dilemma is to use interleaved training to learn a single representation that accommodates all schemas. However, another class of models posits that catastrophic interference can be avoided by splitting off new representations when large prediction errors occur. A key differentiating prediction is that, according to splitting models, catastrophic interference can be prevented even under blocked training curricula. We conducted a series of semi-naturalistic experiments and simulations with Bayesian and neural network models to compare the predictions made by the \"splitting\" versus \"non-splitting\" hypotheses of schema learning. We found better performance in blocked compared to interleaved curricula, and explain these results using a Bayesian model that incorporates representational splitting in response to large prediction errors. In a follow-up experiment, we validated the model prediction that inserting blocked training early in learning leads to better learning performance than inserting blocked training later in learning.

Despite significant advancements in computational resources, there is a vast timescale disparity, more than 6 orders of magnitude, between mechanical properties probed in simulations compared to experiments. Using the theoretical framework of non-affine lattice dynamics (NALD), based on the instantaneous normal modes analysis determined through the dynamical matrix of the system, we study the viscoelastic response of a cross-linked epoxy system of diglycidyl ether of bisphenol A (DGEBA) and poly(oxypropylene) diamine, over many orders of magnitude in deformation frequency, below the glass transition temperature. Predictions of the elastic modulus are satisfactorily validated against the non-equilibrium molecular dynamics simulations in the high-frequency regime, and against experimental data from dynamic mechanical analysis at frequencies $ \\sim 1 {\\rm Hz}$, hence successfully bridging the timescale gap. The comparison shows that non-affine displacements at the atomic level account for nearly two orders of magnitude reduction in the low-frequency elastic modulus of the polymer glass, compared to affine elasticity estimates. The analysis also reveals the role of internal stresses (as reflected in the instantaneous normal modes), which act as to strengthen the mechanical response.", - "doi": null, - "authors": [ - "Vinay Vaibhav", - "Timothy W.

All the fabricated powder filters showed a large attenuation at high frequencies with a cut-off frequency near 1 GHz. However, the toroidal filter showed prominent ripples corresponding to resonance modes in the 0.5-m-long coil wire. A filter with a 2:1 powder/epoxy mixture mass rate and a wire length of 1.53 m showed an attenuation of -93 dB at 4 GHz and the attenuation was linearly proportional to the wire length. As the powder-to-epoxy ratio increased, the high-frequency attenuation increased. An equally-spaced single-layer coil structure was found to be more efficient in attenuation than a double-layer coil. Geometry of the metal filter-case affected noise ripples with the least noise in a circular-tube case.", - "doi": "10.3938/jkps.69.272", - "authors": [ - "Sung Hoon Lee", - "Soon-Gul Lee" - ], - "journal": null, - "tags": [ - "physics.ins-det" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/1605.07597v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/1605.07597v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39329077", - "title": "Hitting the Rewind Button: Imagining Analogue Trauma Memories in Reverse Reduces Distressing Intrusions.", - "content": "Intrusive re-experiencing of trauma is a core symptom of posttraumatic stress disorder.

The mats are spun directly from a floating catalyst, chemical vapour deposition reactor. The volume fraction of epoxy is varied widely by suitable dilution of the epoxy resin with acetone. Subsequent evaporation of the acetone, followed by a cure cycle, leads to composites of varying volume fraction of CNT, epoxy and air. The modulus, strength, electrical conductivity and piezoresistivity of the composites are measured. The CNT mats and their composites exhibit an elastic-plastic stress-strain response under uniaxial tensile loading, and the degree of anisotropy is assessed by testing specimens in 0{\\deg}, 45{\\deg} and 90{\\deg} directions with respect to the draw direction of mat manufacture. The electrical conductivity scales linearly with CNT volume fraction, irrespective of epoxy volume fraction. In contrast, the modulus and strength depend upon both CNT and epoxy volume fractions in a non-linear manner. The macroscopic moduli of the CNT mat-epoxy composites are far below the Voigt bound based on the modulus of CNT walls and epoxy.

The properties and performance of epoxy polymers depend upon various factors like the type of constituents and their proportions used and other process parameters. The conventional way of developing epoxy polymers is usually labor-intensive and may not be fully efficient, which has resulted in epoxy polymers having a limited performance range due to the use of predetermined blend combinations, compositions and development parameters. Hence, in order to experiment with more design parameters, robust and easy computational techniques need to be established. To this end, we developed and analyzed in this study a new machine learning (ML) based approach to predict the mechanical properties of epoxy polymers based on their basic structural features. The results from molecular dynamics (MD) simulations have been used to derive the ML model. The salient feature of our work is that for the development of epoxy polymers based on EPON-862, several new hardeners were explored in addition to the conventionally used ones. The influence of additional parameters like the proportion of curing agent used and the extent of curing on the mechanical properties of epoxy polymers were also investigated. This method can be further extended by providing the epoxy polymer with the desired properties through knowledge of the structural characteristics of its constituents.

The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen. It was evident that the modulus of elasticity property of short fiber composites exhibits an increasing trend with higher fiber content, even at 35 wt%. Moreover, the enhancement of tensile strength for the short fiber size composites reached 72.5 %. However, such tensile strength of thin fiber size/epoxy composites achieved 135.7 % at 25 wt% indicating superior development of this mechanical property.

The anti-hyperglycemic effects of the FOD extract and the pure compounds were studied in mice using the Oral Glucose Tolerance Test (OGTT) and streptozotocin (STZ)-induced diabetes mellitus (DM) models. Molecular docking studies were performed on potent compounds in the binding pockets of enzymes α-glucosidase and α-amylase. The isolations of 11 compounds were isolated from the FOD extract, which comprised teferidine (1), ferutinin (FT) (2), teferin (3), epoxy-jaeschkeanadiol-p-hydroxybenzoate (4), epoxy-jaeschkeanadiol-6-vanillate (5), tovarol-8-angelate (6), leucoferin (7), tovarol-8-p-hydroxybenzoate (8), tovarol-8-vanillate (9), 6-β-p-hydroxybenzoyloxy-germacra-1(10),4-diene (10), and chimgin (11).

They are produced by integrating thin sandwich structures of CNT fiber veils and an ionic liquid-based polymer electrolyte between carbon fiber plies, followed by infusion and curing of an epoxy resin. The resulting structure behaves simultaneously as an electric double-layer capacitor and a structural composite, with flexural modulus of 60 GPa and flexural strength of 153 MPa, combined with 88 mF/g of specific capacitance and the highest power (30 W/kg) and energy (37.5 mWh/kg) densities reported so far for structural supercapacitors. In-situ electrochemical measurements during 4-point bending show that electrochemical performance is retained up to fracture, with minor changes in equivalent series resistance for interleaves under compressive stress. En route to improving interlaminar properties we produce grid-shaped interleaves that enable mechanical interconnection of plies by the stiff epoxy. Synchrotron 3D X-ray tomography analysis of the resulting hierarchical structure confirms the formation of interlaminar epoxy joints. The manuscript discusses encapsulation role of epoxy, demonstrated by charge-discharge measurements of composites immersed in water, a deleterious agent for ionic liquids. Finally, we show different architectures free of current collector and electrical insulators, in which both CNT fiber and CF act as active electrodes.", - "doi": "10.1038/s41598-018-21829-5", - "authors": [ - "Evgeny Senokos", - "Yunfu Ou", - "Juan Jose Torres", - "Federico Sket", - "Carlos Gonzalez", - "Rebeca Marcilla", - "Juan J.

Specifically, we design a complex-domain multilayer perceptron (MLP)-Mixer (CMixer), which utilizes two kinds of complex-domain MLP modules to learn the space and frequency characteristics respectively and then interleaves them to couple the learned properties. The complex-domain computation facilitates the learning on the complex-valued channel data, while the interleaving tightens the coupling of space and frequency domains. These two designs jointly reduce the learning burden, making the physics-inspired CMixer more effective on channel representation learning than existing data-driven approaches.

A combination of optical imaging, scanning electron microscopy and a Raman spectroscopy provide a new rapid tool to unambiguously determine the crack propagation path by simple visual inspection of fracture surface. The results show that interlaminar crossing between CNT veil/CF interfaces is of paramount importance. The crack front alternatingly propagates above and below the CNT-toughened interlayer, significantly improving the fracture toughness of resultant laminates. This mechanism is strongly influenced by the method used to integrate the veils onto the CF.

Using the theoretical framework of non-affine lattice dynamics (NALD), based on the instantaneous normal modes analysis determined through the dynamical matrix of the system, we study the viscoelastic response of a cross-linked epoxy system of diglycidyl ether of bisphenol A (DGEBA) and poly(oxypropylene) diamine, over many orders of magnitude in deformation frequency, below the glass transition temperature. Predictions of the elastic modulus are satisfactorily validated against the non-equilibrium molecular dynamics simulations in the high-frequency regime, and against experimental data from dynamic mechanical analysis at frequencies $ \\sim 1 {\\rm Hz}$, hence successfully bridging the timescale gap. The comparison shows that non-affine displacements at the atomic level account for nearly two orders of magnitude reduction in the low-frequency elastic modulus of the polymer glass, compared to affine elasticity estimates.

Here we show that strontium titanate and potassium tantalate, materials which can exhibit quantum paraelectric behaviour with large field-tunable permittivity at low temperatures, can be used to make varactors with perfect impedance matching and resonator frequency tuning at 6 mK. We characterize the varactors at 6 mK in terms of their capacitance tunability, dissipative losses and magnetic field insensitivity.

Using the theoretical framework of non-affine lattice dynamics (NALD), based on the instantaneous normal modes analysis determined through the dynamical matrix of the system, we study the viscoelastic response of a cross-linked epoxy system of diglycidyl ether of bisphenol A (DGEBA) and poly(oxypropylene) diamine, over many orders of magnitude in deformation frequency, below the glass transition temperature.

The comparison shows that non-affine displacements at the atomic level account for nearly two orders of magnitude reduction in the low-frequency elastic modulus of the polymer glass, compared to affine elasticity estimates.

Subsequent evaporation of the acetone, followed by a cure cycle, leads to composites of varying volume fraction of CNT, epoxy and air.

Hence, in order to experiment with more design parameters, robust and easy computational techniques need to be established. To this end, we developed and analyzed in this study a new machine learning (ML) based approach to predict the mechanical properties of epoxy polymers based on their basic structural features. The results from molecular dynamics (MD) simulations have been used to derive the ML model.

The main objective of this work is to contribute for a better understanding of the static behavior of structure made from fiber reinforced composite materials, specifically for the case of plate structures. The plate model is created using SOLIDWORKS 2017 and then imported into ANSYS R18.1. The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity. This suggests that the composite plate with a cross ply configuration is more suitable for manufacturing composite structures due to its improved performance.", - "journal": "Heliyon", - "issn": [ - "2405-8440" - ], - "authors": [ - "Chala Amsalu", - "Debela Negasa", - "Amanu Merga" - ], - "doi": "10.1016/j.heliyon.2024.e37698", - "publishedDate": "2024-09-09T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39328535", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 1 - ], - "score": 1.0, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1810.00802v1", - "title": "Energy storage in structural composites by introducing CNT fiber/polymer electrolyte interleaves", - "publishedDate": "2018-10-01T16:34:20", - "content": "This work presents a method to produce structural composites capable of energy storage. They are produced by integrating thin sandwich structures of CNT fiber veils and an ionic liquid-based polymer electrolyte between carbon fiber plies, followed by infusion and curing of an epoxy resin. The resulting structure behaves simultaneously as an electric double-layer capacitor and a structural composite, with flexural modulus of 60 GPa and flexural strength of 153 MPa, combined with 88 mF/g of specific capacitance and the highest power (30 W/kg) and energy (37.5 mWh/kg) densities reported so far for structural supercapacitors. In-situ electrochemical measurements during 4-point bending show that electrochemical performance is retained up to fracture, with minor changes in equivalent series resistance for interleaves under compressive stress. En route to improving interlaminar properties we produce grid-shaped interleaves that enable mechanical interconnection of plies by the stiff epoxy. Synchrotron 3D X-ray tomography analysis of the resulting hierarchical structure confirms the formation of interlaminar epoxy joints.

The lack of detailed archival records for some early conservation operations, the identification of restoration materials necessitates the use of scientific analytical methods. In this study, the composition and spatial distribution of historical restoration materials on five iron relics were investigated through pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ultraviolet-induced visible luminescence imaging (UVL). The relics studied were iron weight 20791, iron adze head 2335, and iron axe 2334 from the Gansu Provincial Museum, iron sword D0008 from the Zhaotong Municipal Museum, and iron sword 450 from the National Museum of China. All five relics had undergone restoration without accompanying archival records. UVL revealed the distribution of various conservation materials. Notably, two distinct layers of the conservation material were observed on iron axe 2334. Differences in the fluorescence color and intensity of iron sword 450 provided information regarding the sampling strategy. The samples were collected under ultraviolet light emitting diode illumination to ensure representativeness and minimize damage to the relics. Through Py-GC/MS, the coating materials for iron weight 20791 and iron adze head 2335 were identified as boiled tung oil mixed with rosin resin. Iron axis 2334 had a two-layer coating: a base layer of boiled tung oil and a top layer of shellac. The coating material for iron sword D0008 was determined to be paraffin wax. The protective layer of iron sword 450 included multiple materials, including shellac, polystyrene, and bisphenol-A-type epoxy resin. This study confirms that UVL combined with Py-GC/MS serves as an effective technique for analyzing historical restoration materials. UVL guided the selection of representative samples for Py-GC/MS, reducing the time and amount of sampling required and minimizing further damage to the relics. This research provides valuable data for the restoration archives of five iron artifacts, offering a scientific basis for conservators to evaluate conservation methods, devise future conservation strategies, and exclude ineffective conservation materials.", - "journal": "Se pu = Chinese journal of chromatography", - "issn": [ - "1872-2059" - ], - "authors": [ - "Qin Yang", - "Li Ding", - "Zhao-Hui Li", - "Ran Zhang", - "Yue Wei", - "Ying Chen" - ], - "doi": "10.3724/SP.J.1123.2024.02005", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39327664", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1905.09080v2", - "title": "Interlaminar toughening in structural carbon fiber/epoxy composites interleaved with carbon nanotube veils", - "publishedDate": "2019-05-22T11:34:19", - "content": "The susceptibility to delamination is one of the main concerns in fiber reinforced polymer composites (FRPs). This work demonstrates improvements of 60% in Mode-I fracture toughness after integration of thin (~30 micron), continuous veils of carbon nanotubes (CNTs) directly deposited onto carbon fiber fabric as the CNT are drawn from the gas-phase using a semi-industrial process. A combination of optical imaging, scanning electron microscopy and a Raman spectroscopy provide a new rapid tool to unambiguously determine the crack propagation path by simple visual inspection of fracture surface. The results show that interlaminar crossing between CNT veil/CF interfaces is of paramount importance. The crack front alternatingly propagates above and below the CNT-toughened interlayer, significantly improving the fracture toughness of resultant laminates. This mechanism is strongly influenced by the method used to integrate the veils onto the CF.

The CNT mats and their composites exhibit an elastic-plastic stress-strain response under uniaxial tensile loading, and the degree of anisotropy is assessed by testing specimens in 0{\\deg}, 45{\\deg} and 90{\\deg} directions with respect to the draw direction of mat manufacture. The electrical conductivity scales linearly with CNT volume fraction, irrespective of epoxy volume fraction. In contrast, the modulus and strength depend upon both CNT and epoxy volume fractions in a non-linear manner.

The properties and performance of epoxy polymers depend upon various factors like the type of constituents and their proportions used and other process parameters. The conventional way of developing epoxy polymers is usually labor-intensive and may not be fully efficient, which has resulted in epoxy polymers having a limited performance range due to the use of predetermined blend combinations, compositions and development parameters. Hence, in order to experiment with more design parameters, robust and easy computational techniques need to be established. To this end, we developed and analyzed in this study a new machine learning (ML) based approach to predict the mechanical properties of epoxy polymers based on their basic structural features. The results from molecular dynamics (MD) simulations have been used to derive the ML model. The salient feature of our work is that for the development of epoxy polymers based on EPON-862, several new hardeners were explored in addition to the conventionally used ones. The influence of additional parameters like the proportion of curing agent used and the extent of curing on the mechanical properties of epoxy polymers were also investigated.

While role of solvents in enabling superior mechanical properties has been addressed before, outlined study is the first to address the effect of solvents on thermal conductivity enhancement and provides novel pathways for achieving high thermal conductivity polymer composite materials. Uniform dispersion of graphene nanoparticles into epoxy can improve thermal contact with polymer leading to superior interface thermal conductance between polymer matrix and graphene. Organic solvents are typically employed to achieve efficient dispersion of graphene into the epoxy matrix. In this study, we compare the effect of two organic solvents, dimethylformamide (DMF) and acetone, in terms of their efficiency in dispersing graphene into the epoxy matrix and their effect on enhancing thermal conductivity of the composite. We find that polymer-graphene composites made with DMF solvent show 44% higher thermal conductivity compared to those made using acetone at 7 weight% filler composition. Laser scanning confocal microscopy (LSCM) imaging reveals that graphene-epoxy composites, prepared using DMF as solvent, exhibit more uniform dispersion of graphene-nanoplatelets compared to the case of acetone with acetone-based samples exhibiting up to 211% larger graphene agglomerations. Comparison with effective medium theory reveals an almost 35% lower interface thermal resistance between graphene and epoxy for DMF relative to acetone prepared composite.

This work presents integrated investigations of the lignocellulosic date palm/epoxy composites at various reinforcement condition parameters for sustainable structural materials where elemental mapping, topological analysis, and mechanical performance have been performed. Mapping energy dispersive X-ray spectroscopy was utilized to assess the composite composition properly. Elemental mapping and a scanning electron microscope were employed to evaluate the chemical composition of the composites. The mechanical performance of the produced composites was also explored in terms of ultimate tensile strength, tensile modulus, elongation at break, and impact energy properties. The effects of fiber loading, fiber length, and fiber width (as long fiber, short fiber, and long-thin fiber) were investigated for the date palm fiber/epoxy composites. Results have revealed that the composite behavior was affected by several influential reinforcement parameters. The energy dispersive X-ray spectroscopy maps by C-K, O-K, Si-K, K-K, and Ca-K demonstrated that the composites contain mainly carbon, silicon, and oxygen. It was evident that the modulus of elasticity property of short fiber composites exhibits an increasing trend with higher fiber content, even at 35 wt%. Moreover, the enhancement of tensile strength for the short fiber size composites reached 72.5 %. However, such tensile strength of thin fiber size/epoxy composites achieved 135.7 % at 25 wt% indicating superior development of this mechanical property.

The processing of fiber-reinforced epoxy composite structures requires carefully selected heating and cooling cycles to fully cure the resin and form strong crosslinked networks. To fully optimize the processing parameters for effective epoxy monomer crosslinking and final product integrity, the evolution of mechanical properties of epoxies during processing must be comprehensively understood. Because the full experimental characterization of these properties as a function of the degree of cure is difficult and time-consuming, efficient computational predictive tools are needed. The objective of this research is to develop an experimentally validated Molecular Dynamics (MD) modeling method, which incorporates a reactive force field, to accurately predict the thermo-mechanical properties of an epoxy resin as a function of the degree of cure. Experimental rheometric and mechanical testing are used to validate an MD model which is subsequently used to predict mass density, shrinkage, elastic properties, and yield strength as a function of the degree of cure. The results indicate that each of the physical and mechanical properties evolve uniquely during the crosslinking process.

The anti-hyperglycemic effects of the FOD extract and the pure compounds were studied in mice using the Oral Glucose Tolerance Test (OGTT) and streptozotocin (STZ)-induced diabetes mellitus (DM) models. Molecular docking studies were performed on potent compounds in the binding pockets of enzymes α-glucosidase and α-amylase.

This problem relates to oscillating blood flow in viscoelastic vessels. The deeper motivation for this study, however, is the possible use of compliant coatings for turbulent drag reduction. An analytical solution of the fluid and solid velocity is presented, and five dimensionless parameters emerge. The interaction between fluid and solid appears to be determined by a single combined dimensionless parameter, which we call the shear interaction parameter $\\chi$. The fluid satisfies a no-slip boundary condition when $\\left|\\chi\\right| \\rightarrow 0$, which occurs when the solid is heavy, stiff and/or thin. In contrast, the fluid obeys a free-slip boundary condition when $\\left|\\chi\\right| \\rightarrow \\infty$, which corresponds to a lightweight and/or soft solid. Three types of resonance modes are identified for an elastic solid. Two modes (odd and even) are specific to the solid. The third mode results from the coupling with the fluid. The three modes are less pronounced or even absent for a viscoelastic solid. These findings have a twofold use. First, they help to understand the fluid and solid dynamics when shear coupling is important. Second, the presented analytical solution is very useful for validation of numerical fluid-structure-interaction solvers.

In situ frequency tuning and impedance matching of the resonator circuit using voltage-tunable capacitors (varactors) is needed to optimize read-out sensitivity, but the performance of conventional semiconductor- and ferroelectric-based varactors degrades substantially in the millikelvin temperature range relevant for solid-state quantum devices. Here we show that strontium titanate and potassium tantalate, materials which can exhibit quantum paraelectric behaviour with large field-tunable permittivity at low temperatures, can be used to make varactors with perfect impedance matching and resonator frequency tuning at 6 mK. We characterize the varactors at 6 mK in terms of their capacitance tunability, dissipative losses and magnetic field insensitivity.

Therefore, most of these methods, and certainly the wood anatomical assessment, may benefit from tools based on Artificial Intelligence. In this paper, we apply two transfer learning techniques with Convolutional Neural Networks (CNNs) to a multi-view Congolese wood species dataset including sections from different orientations and viewed at different microscopic magnifications. We explore two feature extraction methods in detail, namely Global Average Pooling (GAP) and Random Encoding of Aggregated Deep Activation Maps (RADAM), for efficient and accurate wood species identification.

Graphene oxide (GO) with a volume range of 0.2 to 0.5 mL was deposited on a 95 mm2 area of thin sheets of Balsa wood with a thickness range of 2.20 - 3.50 mm. The dried GO deposits were laser treated in reduced oxygen environment to prepare a reduced graphene oxide-wood composite (rGO-wood). The rGO substrate of the composite was sandwiched between 2 wood sheets which were glued using polydimethylsiloxane (PDMS) to give a stable membrane. Fabricated membranes improved the Allura red rejection from 8.29 $\\pm$ 0.69% in the controls (sandwiched wood sheets without rGO) to 93.14 $\\pm$ 1.31% in the 1 mL total rGO composites. The ratio of percentage permeance drop of the treatments over the controls ranged from 62.8 $\\pm$ 4.3 to 85.4 $\\pm$ 5.2% from the 0.4 to 1 mL rGO composites respectively. The correlation coefficient (r) between the GO volume and rejection was 0.94 suggesting that the GO treatments provided some control over the transport of molecules through the membrane. The correlation coefficient between wood thickness, and Allura red rejection shows that the wood sheets did not influence the rejection. The permeance was weakly affected by the membrane thickness (r = -0.46). An 93% improvement in rejection performance of the composite membranes over the controls was observed.

Transparent wood (TW) is an emerging biocomposite in this category, which adds optical function to the structural properties of wood. Nano- and microscale inhomogeneities in composition, structure and at interfaces strongly affect light transmission and haze. While interface manipulation can tailor TW properties, the realization of optically clear wood requires detailed understanding of light-TW interaction mechanisms. Here we show how material scattering and absorption coefficients can be extracted from a combination of experimental spectroscopic measurements and a photon diffusion model. Contributions from different length scales can thus be deciphered and quantified. It is shown that forward scattering dominates haze in TW, primarily caused by refractive index mismatch between the wood substrate and the polymer phase. Rayleigh scattering from the wood cell wall and absorption from residual lignin have minor effects on transmittance, but the former affects haze.

However, numerical modeling of stoves is still in its nascent years, thus making it imperative to start adapting more mature computational techniques, established in other combustion-based applications (e.g., combustion engines), to wood stoves. This study focuses on a critical review of the state-of-the-art in wood combustion modeling techniques and on providing recommendations for needed enhancements. In order to develop an optimum conceptual numerical model for wood stoves, the basic processes inside the stove are broken down and isolated into generic computational domains: surface reactions, gas reactions, and the fluid domain. Then state-of-the-art numerical efforts for wood stove and similar applications are broken down in a similar manner to highlight points of strength and possible improvements. Finally, based on the comparison between the different models, an improved modeling approach is proposed as a road map for future research efforts to achieve a higher fidelity wood stove numerical model.", - "doi": null, - "authors": [ - "Mahmoud Koraïem", - "Dimitris Assanis" - ], - "journal": "International Communications in Heat and Mass Transfer, 2021", - "tags": [ - "physics.app-ph" - ], - "comments": "14 pages, 10 figures, 1 table", - "pdf_url": "http://arxiv.org/pdf/2107.09722v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2107.09722v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2210.16173v2", - "title": "Deep Learning Object Detection Approaches to Signal Identification", - "publishedDate": "2022-10-27T02:08:46", - "content": "Traditionally source identification is solved using threshold based energy detection algorithms.

While these algorithms work for the majority of cases, they often fail to detect signals that occupy small frequency bands, fail to distinguish sources with overlapping frequency bands, and cannot detect any signals under a specified signal to noise ratio. Through the conversion of raw signal data to spectrogram, source identification can be framed as an object detection problem. By leveraging modern advancements in deep learning based object detection, we propose a system that manages to alleviate the failure cases encountered when using traditional source identification algorithms.

At these frequencies, one or more grazing Rayleigh waves exist, and the lattice sum for the quasi-periodic Green function ceases to exist. We present a modification of this sum by adding two types of terms to it. The first type adds linear combinations of \"shifted\" Green functions, ensuring that the spatial singularities introduced by these terms are located below the grating and therefore outside of the physical domain. With suitable coefficient choices these terms annihilate the growing contributions in the original lattice sum and yield algebraic convergence. Convergence of arbitrarily high order can be obtained by including sufficiently many shifts. The second type of added terms are quasi-periodic plane wave solutions of the Helmholtz equation which reinstate certain necessary grazing modes without leading to blow-up at Wood anomalies. Using the new quasi-periodic Green function, we establish, for the first time, that the Dirichlet problem of scattering by a smooth doubly periodic scattering surface at a Wood frequency is uniquely solvable. We also present an efficient high-order numerical method based on the this new Green function for the problem of scattering by doubly periodic three-dimensional surfaces at and around Wood frequencies.

Moisture content is a critical attribute of wood chips due to its direct relationship with the final product quality. Conventional techniques for determining moisture content, such as oven-drying, possess some drawbacks in terms of their time-consuming nature, potential sample damage, and lack of real-time feasibility. Furthermore, alternative techniques, including NIR spectroscopy, electrical capacitance, X-rays, and microwaves, have demonstrated potential; nevertheless, they are still constrained by issues related to portability, precision, and the expense of the required equipment. Hence, there is a need for a moisture content determination method that is instant, portable, non-destructive, inexpensive, and precise. This study explores the use of deep learning and machine vision to predict moisture content classes from RGB images of wood chips. A large-scale image dataset comprising 1,600 RGB images of wood chips has been collected and annotated with ground truth labels, utilizing the results of the oven-drying technique.

This study explores the potential of valorizing paper sludge by incorporating it into particleboard production. It aims to optimize sludge content and particle size to enhance board properties-a novel approach to waste management in the wood composites industry. Through systematic variation of sludge content (0-25%) and particle size (< 0.5 to > 2 mm), we assessed the mechanical and physical properties such as internal bond strength (IB), modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA), and thickness swelling (TS). The findings indicate that incorporating paper sludge at moderate levels (5-15%) with optimized particle sizes (< 1 mm) significantly improves the mechanical properties of the particleboard, including increased IB, MOR, and MOE while reducing WA and TS. Principal Component Analysis (PCA) further supported these results, revealing that higher-density boards with enhanced mechanical properties absorb less water, highlighting the interrelationship between structural integrity and moisture resistance. The PCA also identified thickness swelling as an independent factor, suggesting that while mechanical properties can be optimized, additional strategies are needed to control swelling. In conclusion, this study demonstrates that up to 15% paper sludge can be effectively used in particleboard production without compromising quality, provided particle size is carefully controlled.

The key component is a newly proposed latent-variable Gaussian process (LVGP) model through which different classes of microstructures are mapped into a low-dimensional continuous latent space. It provides an interpretable distance metric between classes and captures their effects on the homogenized stiffness tensors. By introducing latent vectors as design variables, a differentiable transition of stiffness matrix between classes can be easily achieved with an analytical gradient. After integrating LVGP with the density-based TO, an efficient data-driven cellular composite optimization process is developed to enable concurrent exploration of microstructure concepts and the associated volume fractions for natural frequency optimization.

To address this, researchers explored compact shaped geometries, with spiral PEH being one such design to lower resonance frequencies by reducing structural stiffness. While trying to achieve this lower resonance frequency, spiral designs overlooked that they were spreading the stress across the structure. This was a significant drawback because it reduced the structure's ability to stress the piezoelectric transducer. The issue remains unaddressed, limiting the power generation of spiral beam harvesters. Furthermore, spiral structures also fail to broaden the operating bandwidth, posing additional constraints on their effectiveness. This study introduces a novel solution - the \"branch spiral beam harvester,\" combining the benefits of both spiral and branch beam designs. The integration of the branch beam concept into the spiral structure aimed to broaden the effective frequency range and establish a concentrated stress area for the placement of the piezoelectric transducer. Finite Element Analysis (FEA) was employed to assess operating bandwidth and stress distribution, while experimental studies evaluated voltage and power generation. Once the workability was confirmed, a statistical optimisation method was introduced to tailor the harvester for specific frequencies in the ultra-low frequency range. Results indicated that the branch spiral beam harvester exhibits a wider operating bandwidth with six natural frequencies in the ultra-low frequency range. It harnessed significantly higher output voltages and power compared to conventional linear PEH. This innovation presents a promising advancement in piezoelectric energy harvesting, offering improved performance without the need for proof masses or additional accessories.", - "journal": "Heliyon", - "issn": [ - "2405-8440" - ], - "authors": [ - "Iresha Erangani Piyarathna", - "Mustafa Ucgul", - "Charles Lemckert", - "Zi Sheng Tang", - "Yee Yan Lim" - ], - "doi": "10.1016/j.heliyon.2024.e34776", - "publishedDate": "2024-07-16T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39165971", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2310.18952v1", - "title": "Exploring the phase diagrams of multidimensional Kuramoto models", - "publishedDate": "2023-10-29T09:46:33", - "content": "The multidimensional Kuramoto model describes the synchronization dynamics of particles moving on the surface of D-dimensional spheres, generalizing the original model where particles were characterized by a single phase. In this setup, particles are more easily represented by $D$-dimensional unit vectors than by $D-1$ spherical angles, allowing for the coupling constant to be extended to a coupling matrix acting on the vectors. As in the original Kuramoto model, each particle has a set of $D(D-1)/2$ natural frequencies, drawn from a distribution. The system has a large number of independent parameters, given by the average natural frequencies, the characteristic widths of their distributions plus $D^2$ constants of the coupling matrix. General phase diagrams, indicating regions in parameter space where the system exhibits different behaviors, are hard to derive analytically. Here we obtain the complete phase diagram for $D=2$ and Lorentzian distributions of natural frequencies using the Ott-Antonsen ansatz. We also explore the diagrams numerically for different distributions and some specific choices of parameters for $D=2$, $D=3$ and $D=4$. In all cases the system exhibits at most four different phases: disordered, static synchrony, rotation and active synchrony.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 7 - ], - "score": 0.14285714285714285, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39328405", - "title": "CXCR1 and CXCR2 are potential neutrophil extracellular trap-related treatment targets in ulcerative colitis: insights from Mendelian randomization, colocalization and transcriptomic analysis.", - "content": "There is already substantial evidence indicating that neutrophil extracellular trap (NET) formation contributes to the inflammatory cascade in ulcerative colitis (UC).

The resulting slicing sites on the target transcripts could be mapped by sequencing of the 3'-cleavage remnants, called degradome sequencing. The high sequence complementarity between miRNAs and their targets has greatly facilitated the development of the target prediction tools for plant miRNAs. The prediction results were then subjected to degradome sequencing data-based validation, through which numerous miRNA-target interactions have been extracted. However, some drawbacks are unavoidable when using this forward approach. Essentially, a known list of plant miRNAs should be obtained in advance of target prediction and validation. This becomes an obstacle to discover novel miRNAs and their targets. Here, after reviewing the current available algorithms for reverse identification of miRNA-target pairs in plants, a case study was performed by using a newly established framework with adjustable parameters. In this workflow, integration of degradome and ARGONAUTE 1-enriched small RNA sequencing data was recommended to do a relatively comprehensive and reliable search. Besides, several computational algorithms such as BLAST, target plots and RNA secondary structure prediction were used.

The $DP$ property of order $p\\in[1,\\infty]$ for Banach spaces was introduced by Castillo and Sanchez in 1993. Being motivated by these notions, for $p,q\\in[1,\\infty]$, we define the strict Dunford--Pettis property of order $p$ (the strict $DP_p$ property) and the sequential Dunford--Pettis property of order $(p,q)$ (the sequential $DP_{(p,q)}$ property). We show that a locally convex space (lcs) $E$ has the $DP$ property iff the space $E$ endowed with the Grothendieck topology $\\tau_{\\Sigma'}$ has the weak Glicksberg property, and $E$ has the strict $DP_p$ property iff the space $(E,\\tau_{\\Sigma'}) $ has the $p$-Schur property. We also characterize lcs with the sequential $DP_{(p,q)}$ property. Some permanent properties and relationships between Dunford--Pettis type properties are studied.

Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes.

The highly efficient synthesis of a wide range of unprecedented thietanes from intrinsically highly unstable thiocabonyls, such as thioaldehydes and aliphatic thioketones, was made possible by the multitasking capability of pyrenacyl sulfides, as a source of thiocarbonyl substrates and as precursors of 1-acetylpyrene, which acts as the photocatalyst for the thia-Paternò-Büchi reaction.

Internationally, resale based property taxes are most common due to ease of implementation and the difficulty of establishing site values. In an Irish context, property valuations are currently based on comparison to recently sold neighbouring properties, however, this approach is limited by low property turnover. National property taxes based on property value, as opposed to site value, also act as a disincentive to improvement works due to the ensuing increased tax burden. In this article we develop a spatial hedonic regression model to separate the spatial and non-spatial contributions of property features to resale value. We mitigate the issue of low property turnover through geographic correlation, borrowing information across multiple property types and finishes. We investigate the impact of address mislabelling on predictive performance, where vendors erroneously supply a more affluent postcode, and evaluate the contribution of improvement works to increased values. Our flexible geo-spatial model outperforms all competitors across a number of different evaluation metrics, including the accuracy of both price prediction and associated uncertainty intervals. While our models are applied in an Irish context, the ability to accurately value properties in markets with low property turnover and to quantify the value contributions of specific property features has widespread application. The ability to separate spatial and non-spatial contributions to a property's value also provides an avenue to site-value based property taxes.", - "doi": "10.1007/s11146-022-09888-y", - "authors": [ - "Aoife K.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways.

In this study, LignoForce™ lignin, a biobased aromatic polymer commercially isolated from wood, was fractioned into two parts using acetone, and the resulting lignin fractions had distinct thermo-rheological behavior. These two fractionated lignins were combined in various ratios and transformed into nanofibers by electrospinning. Subsequently, electrospun fiber materials were disrupted by agitating the mats in water, and the materials were transformed into ultralight 3D aerogels through lyophilization and post-process controlled heating. Using only this combination of two fractions, the morphology of lignin nanofibers was tailored by heat treatment, resulting in lignin aerogels with high flexibility and significant shape recovery properties. Various microscale structures of lignin fibers impacted the resulting physical properties of the elastic aerogel materials, such as resilience, compressive strength, and electrical conductivity for the corresponding carbonized samples.

However, existing multiscale design methods for cellular composites are either computationally exhaustive or confined to a single class of microstructures. In this paper, we propose a data-driven topology optimization (TO) approach to enable the multiscale design of cellular structures with various choices of microstructure classes. The key component is a newly proposed latent-variable Gaussian process (LVGP) model through which different classes of microstructures are mapped into a low-dimensional continuous latent space. It provides an interpretable distance metric between classes and captures their effects on the homogenized stiffness tensors. By introducing latent vectors as design variables, a differentiable transition of stiffness matrix between classes can be easily achieved with an analytical gradient. After integrating LVGP with the density-based TO, an efficient data-driven cellular composite optimization process is developed to enable concurrent exploration of microstructure concepts and the associated volume fractions for natural frequency optimization. Examples reveal that the proposed cellular designs with multiclass microstructures achieve higher natural frequencies than both single-scale and single-class designs.

This study explores the potential of valorizing paper sludge by incorporating it into particleboard production. It aims to optimize sludge content and particle size to enhance board properties-a novel approach to waste management in the wood composites industry. Through systematic variation of sludge content (0-25%) and particle size (< 0.5 to > 2 mm), we assessed the mechanical and physical properties such as internal bond strength (IB), modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA), and thickness swelling (TS). The findings indicate that incorporating paper sludge at moderate levels (5-15%) with optimized particle sizes (< 1 mm) significantly improves the mechanical properties of the particleboard, including increased IB, MOR, and MOE while reducing WA and TS. Principal Component Analysis (PCA) further supported these results, revealing that higher-density boards with enhanced mechanical properties absorb less water, highlighting the interrelationship between structural integrity and moisture resistance. The PCA also identified thickness swelling as an independent factor, suggesting that while mechanical properties can be optimized, additional strategies are needed to control swelling. In conclusion, this study demonstrates that up to 15% paper sludge can be effectively used in particleboard production without compromising quality, provided particle size is carefully controlled.

We parameterized the model by fitting it to HFMD data in mainland China from January 2011 to December 2018, and the basic reproduction number was estimated as 0.9599. Sensitivity analysis demonstrates that transmission between immature and mature individuals contributes substantially to new infections.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency.

This study explores the potential of valorizing paper sludge by incorporating it into particleboard production. It aims to optimize sludge content and particle size to enhance board properties-a novel approach to waste management in the wood composites industry. Through systematic variation of sludge content (0-25%) and particle size (< 0.5 to > 2 mm), we assessed the mechanical and physical properties such as internal bond strength (IB), modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA), and thickness swelling (TS). The findings indicate that incorporating paper sludge at moderate levels (5-15%) with optimized particle sizes (< 1 mm) significantly improves the mechanical properties of the particleboard, including increased IB, MOR, and MOE while reducing WA and TS. Principal Component Analysis (PCA) further supported these results, revealing that higher-density boards with enhanced mechanical properties absorb less water, highlighting the interrelationship between structural integrity and moisture resistance. The PCA also identified thickness swelling as an independent factor, suggesting that while mechanical properties can be optimized, additional strategies are needed to control swelling. In conclusion, this study demonstrates that up to 15% paper sludge can be effectively used in particleboard production without compromising quality, provided particle size is carefully controlled.

This review summarizes different biomass carbon structures and their preparation methods and explores the applications of these materials in electrochemical sensors. Modification of biomass carbon materials through pretreatment, physical and chemical activation, heteroatom doping, metal compound composite and other methods can make up for the deficiencies in its pore structure, electrical conductivity and surface wettability, thereby improving its electrochemical performance. The effects of different biomass sources, functional groups, constituent elements and modification methods on the morphology, structure and electrochemical properties of biomass carbon materials are discussed, and the applications of this type of material in biological molecules, heavy metal ions and pesticide residues are reviewed.

Being motivated by these notions, for $p,q\\in[1,\\infty]$, we define the strict Dunford--Pettis property of order $p$ (the strict $DP_p$ property) and the sequential Dunford--Pettis property of order $(p,q)$ (the sequential $DP_{(p,q)}$ property). We show that a locally convex space (lcs) $E$ has the $DP$ property iff the space $E$ endowed with the Grothendieck topology $\\tau_{\\Sigma'}$ has the weak Glicksberg property, and $E$ has the strict $DP_p$ property iff the space $(E,\\tau_{\\Sigma'}) $ has the $p$-Schur property. We also characterize lcs with the sequential $DP_{(p,q)}$ property. Some permanent properties and relationships between Dunford--Pettis type properties are studied.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

For example, near-magic-angle twisted bilayer graphene (TBG) commonly shows superconductivity, yet a TBG sample with one of the graphene layers rotationally aligned to a hexagonal Boron Nitride (hBN) cladding layer provided experimental observation of orbital ferromagnetism. To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

In an Irish context, property valuations are currently based on comparison to recently sold neighbouring properties, however, this approach is limited by low property turnover. National property taxes based on property value, as opposed to site value, also act as a disincentive to improvement works due to the ensuing increased tax burden. In this article we develop a spatial hedonic regression model to separate the spatial and non-spatial contributions of property features to resale value. We mitigate the issue of low property turnover through geographic correlation, borrowing information across multiple property types and finishes. We investigate the impact of address mislabelling on predictive performance, where vendors erroneously supply a more affluent postcode, and evaluate the contribution of improvement works to increased values. Our flexible geo-spatial model outperforms all competitors across a number of different evaluation metrics, including the accuracy of both price prediction and associated uncertainty intervals. While our models are applied in an Irish context, the ability to accurately value properties in markets with low property turnover and to quantify the value contributions of specific property features has widespread application. The ability to separate spatial and non-spatial contributions to a property's value also provides an avenue to site-value based property taxes.", - "doi": "10.1007/s11146-022-09888-y", - "authors": [ - "Aoife K.

How these factors influence the mechanics of thin films subject to micro-ballistic impact remains to be fully understood. Here we examine the micro-ballistic impact resistance of PGN thin films with polymethyl methacrylate (PMMA) grafts using coarse-grained molecular dynamics simulations.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

We mimic the periodic outbreak of HFMD over a 2-year period-with differing amplitudes-and propose a dynamic HFMD model that differentiates transmission between mature and immature individuals and uses two possible optimal-control strategies to minimize case numbers, total costs and deaths. We parameterized the model by fitting it to HFMD data in mainland China from January 2011 to December 2018, and the basic reproduction number was estimated as 0.9599.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case.

However, existing multiscale design methods for cellular composites are either computationally exhaustive or confined to a single class of microstructures. In this paper, we propose a data-driven topology optimization (TO) approach to enable the multiscale design of cellular structures with various choices of microstructure classes. The key component is a newly proposed latent-variable Gaussian process (LVGP) model through which different classes of microstructures are mapped into a low-dimensional continuous latent space. It provides an interpretable distance metric between classes and captures their effects on the homogenized stiffness tensors. By introducing latent vectors as design variables, a differentiable transition of stiffness matrix between classes can be easily achieved with an analytical gradient. After integrating LVGP with the density-based TO, an efficient data-driven cellular composite optimization process is developed to enable concurrent exploration of microstructure concepts and the associated volume fractions for natural frequency optimization. Examples reveal that the proposed cellular designs with multiclass microstructures achieve higher natural frequencies than both single-scale and single-class designs.

To assess the random vibration properties of a composite sandwich panel with a Tri-Chi honeycomb core (CSP-TCH), a two-dimensional equivalent Reissner-Mindlin model (2D-ERM) was created using the variational asymptotic method. The precision of the 2D-ERM in free and random vibration analysis was confirmed through numerical simulations employing 3D finite element analysis, encompassing PSD curves and RMS responses. Furthermore, the effects of selecting the model class were quantified through dynamic numerical examples. Modal analysis revealed that the relative error of the first eight natural frequencies predicted by the 2D-ERM consistently remained below 7%, with the modal cloud demonstrating high reliability. The PSD curves and their RMS values closely aligned with 3D finite element results under various boundary conditions, with a maximum error below 5%. Key factors influencing the vibration characteristics included the ligament-rib angle of the core layer and layup modes of the composite facesheets, while the rib-to-ligament thickness ratio and the aspect ratio exert minimal influence. The impact of the ligament-rib angle on the vibration properties primarily stems from the significant shift in the core layer's Poisson's ratio, transitioning from negative to positive.

Nonetheless, the conventional linear piezoelectric energy harvesters (PEH) face limitations in ultra-low frequency vibrations (1-10 Hz) due to their narrow operating bandwidth and higher resonance frequencies. To address this, researchers explored compact shaped geometries, with spiral PEH being one such design to lower resonance frequencies by reducing structural stiffness. While trying to achieve this lower resonance frequency, spiral designs overlooked that they were spreading the stress across the structure. This was a significant drawback because it reduced the structure's ability to stress the piezoelectric transducer. The issue remains unaddressed, limiting the power generation of spiral beam harvesters. Furthermore, spiral structures also fail to broaden the operating bandwidth, posing additional constraints on their effectiveness. This study introduces a novel solution - the \"branch spiral beam harvester,\" combining the benefits of both spiral and branch beam designs. The integration of the branch beam concept into the spiral structure aimed to broaden the effective frequency range and establish a concentrated stress area for the placement of the piezoelectric transducer. Finite Element Analysis (FEA) was employed to assess operating bandwidth and stress distribution, while experimental studies evaluated voltage and power generation. Once the workability was confirmed, a statistical optimisation method was introduced to tailor the harvester for specific frequencies in the ultra-low frequency range. Results indicated that the branch spiral beam harvester exhibits a wider operating bandwidth with six natural frequencies in the ultra-low frequency range. It harnessed significantly higher output voltages and power compared to conventional linear PEH. This innovation presents a promising advancement in piezoelectric energy harvesting, offering improved performance without the need for proof masses or additional accessories.", - "journal": "Heliyon", -

Cointegration is used in this paper to remove effects from Environmental and Operational Variations, by cointegrating the first four natural frequencies for the Z24 Bridge data. The temperature effects on the natural frequency data are clearly visible within the data, and it is desirable, for the purposes of structural health monitoring, that these effects are removed. The univariate time series are embedded in higher-dimensional space, such that interesting topologies are formed. Topological data analysis is used to analyse the raw time series, and the cointegrated equivalents. A standard topological data analysis pipeline is enacted, where simplicial complexes are constructed from the embedded point clouds.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Here we provide a rigorous description of the stability of various multicluster states by studying their spectral properties in the thermodynamic limit.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes.

We address this open problem by studying the Synchrony Alignment Function (SAF), which is an objective measure for the synchronization properties of a network of heterogeneous oscillators with given natural frequencies. We extend the SAF framework to analyze network-coupled oscillators with heterogeneous natural frequencies that are drawn as a multivariate random vector. Using probability theory for quadratic forms, we obtain expressions for the expectation and variance of the SAF for given network structures.

However, the stochasticity of operational systems and the lack of forcing information can lead to inconsistent results. Quantifying the uncertainty of the recovered modal parameters through OMA is therefore of significant value. In this article, a new perspective on Bayesian OMA is proposed: a Bayesian stochastic subspace identification (SSI) algorithm. Distinct from existing approaches to Bayesian OMA, a hierarchical probabilistic model is embedded at the core of covariance-driven SSI. Through substitution of canonical correlation analysis with a Bayesian equivalent, posterior distributions over the modal properties are obtained. Two inference schemes are presented for the proposed Bayesian formulation: Markov Chain Monte Carlo and variational Bayes. Two case studies are then explored. The first is benchmark study using data from a simulated, multi degree-of-freedom, linear system. Following application of Bayesian SSI, it is shown that the same posterior is targeted and recovered by both inference schemes, with good agreement between the posterior mean and the conventional SSI result. The second study applies the variational form to data obtained from an in-service structure: The Z24 bridge. The results of this study are presented at single model orders, and then using a stabilisation diagram. The recovered posterior uncertainty is presented and compared to the classic SSI result. It is observed that the posterior distributions with mean values coinciding with the natural frequencies exhibit lower variance than values situated away from the natural frequencies.", - "doi": null, - "authors": [ - "Brandon J.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case.

"content": "In matched observational studies, the inferred causal conclusions pretending that matching has taken into account all confounding can be sensitive to unmeasured confounding. In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331416", - "title": "Myelin Sheath-Inspired Hydrogel Electrode for Artificial Skin and Physiological Monitoring.", - "content": "Significant advancements in hydrogel-based epidermal electrodes have been made in recent years.

In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

While the static sensitivity analysis focuses on the impact of network topology and update functions, the dynamic analysis accounts for context-dependent transient state distributions. To study sensitivity, we use discrete models, where each element is represented as a discrete variable and assigned an update rule, which is a function of element's known direct and indirect regulators. Our sensitivity analysis framework allows for assessing the effect of context on individual element sensitivity, as well as on element criticality in reaching preferred outcomes. The framework also enables discovery of most influential pathways in the model that are essential for satisfying important system properties, and thus, could be used for interventions. We discuss the role of nine different network attributes in identifying key elements and intervention pathways, and evaluate their performance using model checking method.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

In this study, L. paracasei, L. plantarum, and P. pentosaceus fermentation on the IgE-/IgG-binding ability was determined by Enzyme-Linked Immunosorbent Assay (ELISA), and the protein quality, amino acid profile, and color were systematically evaluated.

These findings provided a theoretical foundation for the development of hypoallergenic dairy products.

Our innovative methodology is designed for excursion sets, but is versatile enough to be applied to set-valued simulators, including those found in viability fields, or when working with maps like pollutant concentration maps or flood zone maps. We propose to use the Hilbert-Schmidt Independence Criterion (HSIC) with a kernel designed for set-valued outputs. After proposing a probabilistic framework for random sets, a first contribution is the proof that this kernel is characteristic, an essential property in a kernel-based sensitivity analysis context. To measure the contribution of each input, we then propose to use HSIC-ANOVA indices. With these indices, we can identify which inputs should be neglected (screening) and we can rank the others according to their influence (ranking). The estimation of these indices is also adapted to the set-valued outputs.

As the evaluations of prognostic capacity, the survivals of groups with high/low expression of the biomarker are often estimated by the Kaplan-Meier method, and the difference between groups is summarized via the hazard ratio (HR). The high/low expressions are usually determined by study-specific cutoff values, which brings heterogeneity over multiple prognosis studies and difficulty to synthesizing the results in a simple way. In meta-analysis of diagnostic studies with binary outcomes, the summary receiver operating characteristics (SROC) analysis provides a useful cutoff-free summary over studies. Recently, this methodology has been extended to the time-dependent SROC analysis for time-to-event outcomes in meta-analysis of prognosis studies. In this paper, we propose a sensitivity analysis method for evaluating the impact of publication bias on the time-dependent SROC analysis. Our proposal extends the recently introduced sensitivity analysis method for meta-analysis of diagnostic studies based on the bivariate normal model on sensitivity and specificity pairs. To model the selective publication process specific to prognosis studies, we introduce a trivariate model on the time-dependent sensitivity and specificity and the log-transformed HR. Based on the proved asymptotic property of the trivariate model, we introduce a likelihood based sensitivity analysis method based on the conditional likelihood constrained by the expected proportion of published studies.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways.

On the other hand, moment-independent sensitivity indices focus on the impact of input variables on the whole output distribution instead of the variance only, thus providing complementary insight on the inputs / output relationship. Unfortunately they do not enjoy the nice decomposition property of Sobol' indices and are consequently harder to analyze. In this paper, we introduce two moment-independent indices based on kernel-embeddings of probability distributions and show that the RKHS framework used for their definition makes it possible to exhibit a kernel-based ANOVA decomposition. This is the first time such a desirable property is proved for sensitivity indices apart from Sobol' ones.

Being motivated by these notions, for $p,q\\in[1,\\infty]$, we define the strict Dunford--Pettis property of order $p$ (the strict $DP_p$ property) and the sequential Dunford--Pettis property of order $(p,q)$ (the sequential $DP_{(p,q)}$ property). We show that a locally convex space (lcs) $E$ has the $DP$ property iff the space $E$ endowed with the Grothendieck topology $\\tau_{\\Sigma'}$ has the weak Glicksberg property, and $E$ has the strict $DP_p$ property iff the space $(E,\\tau_{\\Sigma'}) $ has the $p$-Schur property.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

For example, near-magic-angle twisted bilayer graphene (TBG) commonly shows superconductivity, yet a TBG sample with one of the graphene layers rotationally aligned to a hexagonal Boron Nitride (hBN) cladding layer provided experimental observation of orbital ferromagnetism. To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

The highly efficient synthesis of a wide range of unprecedented thietanes from intrinsically highly unstable thiocabonyls, such as thioaldehydes and aliphatic thioketones, was made possible by the multitasking capability of pyrenacyl sulfides, as a source of thiocarbonyl substrates and as precursors of 1-acetylpyrene, which acts as the photocatalyst for the thia-Paternò-Büchi reaction.

Internationally, resale based property taxes are most common due to ease of implementation and the difficulty of establishing site values. In an Irish context, property valuations are currently based on comparison to recently sold neighbouring properties, however, this approach is limited by low property turnover. National property taxes based on property value, as opposed to site value, also act as a disincentive to improvement works due to the ensuing increased tax burden. In this article we develop a spatial hedonic regression model to separate the spatial and non-spatial contributions of property features to resale value. We mitigate the issue of low property turnover through geographic correlation, borrowing information across multiple property types and finishes. We investigate the impact of address mislabelling on predictive performance, where vendors erroneously supply a more affluent postcode, and evaluate the contribution of improvement works to increased values. Our flexible geo-spatial model outperforms all competitors across a number of different evaluation metrics, including the accuracy of both price prediction and associated uncertainty intervals. While our models are applied in an Irish context, the ability to accurately value properties in markets with low property turnover and to quantify the value contributions of specific property features has widespread application. The ability to separate spatial and non-spatial contributions to a property's value also provides an avenue to site-value based property taxes.", - "doi": "10.1007/s11146-022-09888-y", - "authors": [ - "Aoife K.

The grafted chain length and nanoparticle core densities are systematically varied to understand the influences of interparticle spacing, cohesion, and momentum transfer effects under high-velocity impact.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

We parameterized the model by fitting it to HFMD data in mainland China from January 2011 to December 2018, and the basic reproduction number was estimated as 0.9599. Sensitivity analysis demonstrates that transmission between immature and mature individuals contributes substantially to new infections.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39328405", - "title": "CXCR1 and CXCR2 are potential neutrophil extracellular trap-related treatment targets in ulcerative colitis: insights from Mendelian randomization, colocalization and transcriptomic analysis.", - "content": "There is already substantial evidence indicating that neutrophil extracellular trap (NET) formation contributes to the inflammatory cascade in ulcerative colitis (UC).

In this study, LignoForce™ lignin, a biobased aromatic polymer commercially isolated from wood, was fractioned into two parts using acetone, and the resulting lignin fractions had distinct thermo-rheological behavior. These two fractionated lignins were combined in various ratios and transformed into nanofibers by electrospinning. Subsequently, electrospun fiber materials were disrupted by agitating the mats in water, and the materials were transformed into ultralight 3D aerogels through lyophilization and post-process controlled heating. Using only this combination of two fractions, the morphology of lignin nanofibers was tailored by heat treatment, resulting in lignin aerogels with high flexibility and significant shape recovery properties. Various microscale structures of lignin fibers impacted the resulting physical properties of the elastic aerogel materials, such as resilience, compressive strength, and electrical conductivity for the corresponding carbonized samples.

However, existing multiscale design methods for cellular composites are either computationally exhaustive or confined to a single class of microstructures. In this paper, we propose a data-driven topology optimization (TO) approach to enable the multiscale design of cellular structures with various choices of microstructure classes. The key component is a newly proposed latent-variable Gaussian process (LVGP) model through which different classes of microstructures are mapped into a low-dimensional continuous latent space. It provides an interpretable distance metric between classes and captures their effects on the homogenized stiffness tensors. By introducing latent vectors as design variables, a differentiable transition of stiffness matrix between classes can be easily achieved with an analytical gradient. After integrating LVGP with the density-based TO, an efficient data-driven cellular composite optimization process is developed to enable concurrent exploration of microstructure concepts and the associated volume fractions for natural frequency optimization. Examples reveal that the proposed cellular designs with multiclass microstructures achieve higher natural frequencies than both single-scale and single-class designs.

This study explores the potential of valorizing paper sludge by incorporating it into particleboard production. It aims to optimize sludge content and particle size to enhance board properties-a novel approach to waste management in the wood composites industry. Through systematic variation of sludge content (0-25%) and particle size (< 0.5 to > 2 mm), we assessed the mechanical and physical properties such as internal bond strength (IB), modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA), and thickness swelling (TS). The findings indicate that incorporating paper sludge at moderate levels (5-15%) with optimized particle sizes (< 1 mm) significantly improves the mechanical properties of the particleboard, including increased IB, MOR, and MOE while reducing WA and TS. Principal Component Analysis (PCA) further supported these results, revealing that higher-density boards with enhanced mechanical properties absorb less water, highlighting the interrelationship between structural integrity and moisture resistance. The PCA also identified thickness swelling as an independent factor, suggesting that while mechanical properties can be optimized, additional strategies are needed to control swelling. In conclusion, this study demonstrates that up to 15% paper sludge can be effectively used in particleboard production without compromising quality, provided particle size is carefully controlled.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration. The advanced biomimetic hydrogel holds tremendous potential for applications in electronic skin (e-skin), human-machine interfaces (HMIs), and healthcare assessment devices.", - "journal": "ACS nano", - "issn": [ - "1936-086X" - ], - "authors": [ - "Chencong Liu", - "Yuanyuan Wang", - "Shitao Shi", - "Yubo Zheng", - "Zewei Ye", - "Jiaqi Liao", - "Qingfeng Sun", - "Baokang Dang", - "Xiaoping Shen" - ], - "doi": "10.1021/acsnano.4c07677", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331416", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2212.11727v1", - "title": "A topological analysis of cointegrated data: a Z24 Bridge case study", - "publishedDate": "2022-09-12T12:07:00", - "content": "The paper studies the topological changes from before and after cointegration, for the natural frequencies of the Z24 Bridge. The second natural frequency is known to be nonlinear in temperature, and this will serve as the main focal point of this work. Cointegration is a method of normalising time series data with respect to one another - often strongly-correlated time series. Cointegration is used in this paper to remove effects from Environmental and Operational Variations, by cointegrating the first four natural frequencies for the Z24 Bridge data. The temperature effects on the natural frequency data are clearly visible within the data, and it is desirable, for the purposes of structural health monitoring, that these effects are removed. The univariate time series are embedded in higher-dimensional space, such that interesting topologies are formed. Topological data analysis is used to analyse the raw time series, and the cointegrated equivalents. A standard topological data analysis pipeline is enacted, where simplicial complexes are constructed from the embedded point clouds.

For example, near-magic-angle twisted bilayer graphene (TBG) commonly shows superconductivity, yet a TBG sample with one of the graphene layers rotationally aligned to a hexagonal Boron Nitride (hBN) cladding layer provided experimental observation of orbital ferromagnetism. To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

Here we provide a rigorous description of the stability of various multicluster states by studying their spectral properties in the thermodynamic limit. Not unlike the classical Kuramoto model, a natural frequency distribution with infinite support yields a population of drifting oscillators, which in turn guarantees that a portion of the spectrum is located on the imaginary axes, resulting in neutrally stable or unstable solutions.

To our knowledge, systematic studies about the effects of Lactobacillus paracasei, Lactobacillus plantarum, and Pediococcus pentosaceus on the IgE-/IgG-binding ability and nutritional properties of CM are very rare. In this study, L. paracasei, L. plantarum, and P. pentosaceus fermentation on the IgE-/IgG-binding ability was determined by Enzyme-Linked Immunosorbent Assay (ELISA), and the protein quality, amino acid profile, and color were systematically evaluated.

We address this open problem by studying the Synchrony Alignment Function (SAF), which is an objective measure for the synchronization properties of a network of heterogeneous oscillators with given natural frequencies. We extend the SAF framework to analyze network-coupled oscillators with heterogeneous natural frequencies that are drawn as a multivariate random vector. Using probability theory for quadratic forms, we obtain expressions for the expectation and variance of the SAF for given network structures.

The design problem is then transformed into an optimization problem, using kinematic equations as the objective function and the dynamical equation as a constraint. By solving this optimization problem, the optimal dimensional parameters are determined. Six prototypes are manufactured to validate the proposed approach.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

However, the stochasticity of operational systems and the lack of forcing information can lead to inconsistent results. Quantifying the uncertainty of the recovered modal parameters through OMA is therefore of significant value. In this article, a new perspective on Bayesian OMA is proposed: a Bayesian stochastic subspace identification (SSI) algorithm. Distinct from existing approaches to Bayesian OMA, a hierarchical probabilistic model is embedded at the core of covariance-driven SSI. Through substitution of canonical correlation analysis with a Bayesian equivalent, posterior distributions over the modal properties are obtained. Two inference schemes are presented for the proposed Bayesian formulation: Markov Chain Monte Carlo and variational Bayes. Two case studies are then explored. The first is benchmark study using data from a simulated, multi degree-of-freedom, linear system. Following application of Bayesian SSI, it is shown that the same posterior is targeted and recovered by both inference schemes, with good agreement between the posterior mean and the conventional SSI result. The second study applies the variational form to data obtained from an in-service structure: The Z24 bridge. The results of this study are presented at single model orders, and then using a stabilisation diagram. The recovered posterior uncertainty is presented and compared to the classic SSI result. It is observed that the posterior distributions with mean values coinciding with the natural frequencies exhibit lower variance than values situated away from the natural frequencies.", - "doi": null, - "authors": [ - "Brandon J.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 7 - ], - "score": 0.14285714285714285, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39328405", - "title": "CXCR1 and CXCR2 are potential neutrophil extracellular trap-related treatment targets in ulcerative colitis: insights from Mendelian randomization, colocalization and transcriptomic analysis.", - "content": "There is already substantial evidence indicating that neutrophil extracellular trap (NET) formation contributes to the inflammatory cascade in ulcerative colitis (UC).

This review summarizes different biomass carbon structures and their preparation methods and explores the applications of these materials in electrochemical sensors. Modification of biomass carbon materials through pretreatment, physical and chemical activation, heteroatom doping, metal compound composite and other methods can make up for the deficiencies in its pore structure, electrical conductivity and surface wettability, thereby improving its electrochemical performance. The effects of different biomass sources, functional groups, constituent elements and modification methods on the morphology, structure and electrochemical properties of biomass carbon materials are discussed, and the applications of this type of material in biological molecules, heavy metal ions and pesticide residues are reviewed.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331413", - "title": "Deterministic fabrication of graphene hexagonal boron nitride moiré superlattices.", - "content": "The electronic properties of moiré heterostructures depend sensitively on the relative orientation between layers of the stack.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

To study sensitivity, we use discrete models, where each element is represented as a discrete variable and assigned an update rule, which is a function of element's known direct and indirect regulators. Our sensitivity analysis framework allows for assessing the effect of context on individual element sensitivity, as well as on element criticality in reaching preferred outcomes. The framework also enables discovery of most influential pathways in the model that are essential for satisfying important system properties, and thus, could be used for interventions. We discuss the role of nine different network attributes in identifying key elements and intervention pathways, and evaluate their performance using model checking method.

Altogether, we show in this review the potential of RuII acetylide compounds, insisting on the molecular design and suggesting further research developments for this class of organometallic dyes, including supramolecular chemistry.", - "journal": "Chemistry (Weinheim an der Bergstrasse, Germany)", - "issn": [ - "1521-3765" - ], - "authors": [ - "Olivier Galangau", - "Stephane Rigaut" - ], - "doi": "10.1002/chem.202402788", - "publishedDate": "2024-09-27T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331384", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 6 - ], - "score": 0.16666666666666666, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2305.09268v3", - "title": "Kernel-based sensitivity analysis for (excursion) sets", - "publishedDate": "2023-05-16T08:20:26", - "content": "In this paper, we aim to perform sensitivity analysis of set-valued models and, in particular, to quantify the impact of uncertain inputs on feasible sets, which are key elements in solving a robust optimization problem under constraints. While most sensitivity analysis methods deal with scalar outputs, this paper introduces a novel approach for performing sensitivity analysis with set-valued outputs. Our innovative methodology is designed for excursion sets, but is versatile enough to be applied to set-valued simulators, including those found in viability fields, or when working with maps like pollutant concentration maps or flood zone maps. We propose to use the Hilbert-Schmidt Independence Criterion (HSIC) with a kernel designed for set-valued outputs. After proposing a probabilistic framework for random sets, a first contribution is the proof that this kernel is characteristic, an essential property in a kernel-based sensitivity analysis context. To measure the contribution of each input, we then propose to use HSIC-ANOVA indices. With these indices, we can identify which inputs should be neglected (screening) and we can rank the others according to their influence (ranking). The estimation of these indices is also adapted to the set-valued outputs. Finally, we test the proposed method on three test cases of excursion sets.", - "doi": null, - "authors": [ - "Noé Fellmann", - "Christophette Blanchet-Scalliet", - "Céline Helbert", - "Adrien Spagnol", - "Delphine Sinoquet" - ], - "journal": null, - "tags": [ - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2305.09268v3", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2305.09268v3", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 6 - ], - "score": 0.16666666666666666, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331362", - "title": "Micro-ballistic response of thin film polymer grafted nanoparticle monolayers.", - "content": "Self-assembled polymer grafted nanoparticles (PGNs) are of great interest for their potential to enhance mechanical properties compared to neat polymers and nanocomposites.

How these factors influence the mechanics of thin films subject to micro-ballistic impact remains to be fully understood. Here we examine the micro-ballistic impact resistance of PGN thin films with polymethyl methacrylate (PMMA) grafts using coarse-grained molecular dynamics simulations.

As the evaluations of prognostic capacity, the survivals of groups with high/low expression of the biomarker are often estimated by the Kaplan-Meier method, and the difference between groups is summarized via the hazard ratio (HR). The high/low expressions are usually determined by study-specific cutoff values, which brings heterogeneity over multiple prognosis studies and difficulty to synthesizing the results in a simple way. In meta-analysis of diagnostic studies with binary outcomes, the summary receiver operating characteristics (SROC) analysis provides a useful cutoff-free summary over studies. Recently, this methodology has been extended to the time-dependent SROC analysis for time-to-event outcomes in meta-analysis of prognosis studies. In this paper, we propose a sensitivity analysis method for evaluating the impact of publication bias on the time-dependent SROC analysis. Our proposal extends the recently introduced sensitivity analysis method for meta-analysis of diagnostic studies based on the bivariate normal model on sensitivity and specificity pairs. To model the selective publication process specific to prognosis studies, we introduce a trivariate model on the time-dependent sensitivity and specificity and the log-transformed HR. Based on the proved asymptotic property of the trivariate model, we introduce a likelihood based sensitivity analysis method based on the conditional likelihood constrained by the expected proportion of published studies. We illustrate the proposed sensitivity analysis method through the meta-analysis of Ki67 for breast cancer.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

In particular when the inputs are independent, Sobol' sensitivity indices attribute a portion of the output of interest variance to each input and all possible interactions in the model, thanks to a functional ANOVA decomposition. On the other hand, moment-independent sensitivity indices focus on the impact of input variables on the whole output distribution instead of the variance only, thus providing complementary insight on the inputs / output relationship. Unfortunately they do not enjoy the nice decomposition property of Sobol' indices and are consequently harder to analyze. In this paper, we introduce two moment-independent indices based on kernel-embeddings of probability distributions and show that the RKHS framework used for their definition makes it possible to exhibit a kernel-based ANOVA decomposition. This is the first time such a desirable property is proved for sensitivity indices apart from Sobol' ones. When the inputs are dependent, we also use these new sensitivity indices as building blocks to design kernel-embedding Shapley effects which generalize the traditional variance-based ones used in sensitivity analysis. Several estimation procedures are discussed and illustrated on test cases with various output types such as categorical variables and probability distributions.

Being motivated by these notions, for $p,q\\in[1,\\infty]$, we define the strict Dunford--Pettis property of order $p$ (the strict $DP_p$ property) and the sequential Dunford--Pettis property of order $(p,q)$ (the sequential $DP_{(p,q)}$ property). We show that a locally convex space (lcs) $E$ has the $DP$ property iff the space $E$ endowed with the Grothendieck topology $\\tau_{\\Sigma'}$ has the weak Glicksberg property, and $E$ has the strict $DP_p$ property iff the space $(E,\\tau_{\\Sigma'}) $ has the $p$-Schur property.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Internationally, resale based property taxes are most common due to ease of implementation and the difficulty of establishing site values. In an Irish context, property valuations are currently based on comparison to recently sold neighbouring properties, however, this approach is limited by low property turnover. National property taxes based on property value, as opposed to site value, also act as a disincentive to improvement works due to the ensuing increased tax burden. In this article we develop a spatial hedonic regression model to separate the spatial and non-spatial contributions of property features to resale value. We mitigate the issue of low property turnover through geographic correlation, borrowing information across multiple property types and finishes. We investigate the impact of address mislabelling on predictive performance, where vendors erroneously supply a more affluent postcode, and evaluate the contribution of improvement works to increased values. Our flexible geo-spatial model outperforms all competitors across a number of different evaluation metrics, including the accuracy of both price prediction and associated uncertainty intervals. While our models are applied in an Irish context, the ability to accurately value properties in markets with low property turnover and to quantify the value contributions of specific property features has widespread application.

Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay.

We mimic the periodic outbreak of HFMD over a 2-year period-with differing amplitudes-and propose a dynamic HFMD model that differentiates transmission between mature and immature individuals and uses two possible optimal-control strategies to minimize case numbers, total costs and deaths. We parameterized the model by fitting it to HFMD data in mainland China from January 2011 to December 2018, and the basic reproduction number was estimated as 0.9599. Sensitivity analysis demonstrates that transmission between immature and mature individuals contributes substantially to new infections. Increasing the isolation rates of infectious individuals-particularly mature infectious individuals-could greatly reduce the outbreak risk and potentially eradicate the disease in a relatively short time period.

By introducing an indicator to evaluate how far a system is from its steady state, both the trend of entropy and the radiative process' contribution to the lifetime of excited states were considered. The high statistical weight of some excited states may act as a bottleneck in the plasma's energy relaxation throughout the system to a steady state.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, unmeasured confounding may exist and cannot be removed by matching. Therefore, a sensitivity analysis is typically needed to assess a causal conclusion's sensitivity to unmeasured confounding. Sensitivity analysis frameworks for binary exposures have been well-established for various matching designs and are commonly used in various studies. However, unlike the binary exposure case, there still lacks valid and general sensitivity analysis methods for continuous exposures, except in some special cases such as pair matching. To fill this gap in the binary outcome case, we develop a sensitivity analysis framework for general matching designs with continuous exposures and binary outcomes. First, we use probabilistic lattice theory to show our sensitivity analysis approach is finite-population-exact under Fisher's sharp null. Second, we prove a novel design sensitivity formula as a powerful tool for asymptotically evaluating the performance of our sensitivity analysis approach. Third, to allow effect heterogeneity with binary outcomes, we introduce a framework for conducting asymptotically exact inference and sensitivity analysis on generalized attributable effects with binary outcomes via mixed-integer programming. Fourth, for the continuous outcomes case, we show that conducting an asymptotically exact sensitivity analysis in matched observational studies when both the exposures and outcomes are continuous is generally NP-hard, except in some special cases such as pair matching.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39328281", - "title": "Higher 10-Year Survival with Breast-Conserving Therapy over Mastectomy for Women with Early-Stage (I-II) Breast Cancer: Analysis of the CDC Patterns of Care Data Base.", - "content": "Studies in the United States are scarce that assess the survival differences between breast-conserving surgery plus radiation (Breast-Conserving Therapy; BCT) and mastectomy groups using population-based data while accounting for sociodemographic and clinical factors that affect the survival of women with early-stage breast cancer (ESBC).", - "journal": "Breast cancer : basic and clinical research", - "issn": [ - "1178-2234" - ], - "authors": [ - "Pratibha Shrestha", - "Mei-Chin Hsieh", - "Tekeda Ferguson", - "Edward S Peters", - "Edward Trapido", - "Qingzhao Yu", - "Quyen D Chu", - "Xiao-Cheng Wu" - ], - "doi": "10.1177/11782234241273666", - "publishedDate": "2024-07-07T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39328281", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1712.03605v1", - "title": "Sensitivity Analysis for Predictive Uncertainty in Bayesian Neural Networks", - "publishedDate": "2017-12-10T22:57:42", - "content": "We derive a novel sensitivity analysis of input variables for predictive epistemic and aleatoric uncertainty.

In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer. This work demonstrates a key step toward systematically exploring the effects of the relative twist angle between dissimilar materials within moiré heterostructures.", - "journal": "Proceedings of the National Academy of Sciences of the United States of America", - "issn": [ - "1091-6490" - ], - "authors": [ - "Rupini V Kamat", - "Aaron L Sharpe", - "Mihir Pendharkar", - "Jenny Hu", - "Steven J Tran", - "Gregory Zaborski", - "Marisa Hocking", - "Joe Finney", - "Kenji Watanabe", - "Takashi Taniguchi", - "Marc A Kastner", - "Andrew J Mannix", - "Tony Heinz", - "David Goldhaber-Gordon" - ], - "doi": "10.1073/pnas.2410993121", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331413", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331406", - "title": "Assessment of the effect of lactic acid bacteria fermentation on IgE-/IgG-binding ability and nutritional properties of cow milk.", - "content": "Cow milk (CM) is an important food source for humans, and food allergy caused by CM has attracted attention worldwide. To our knowledge, systematic studies about the effects of Lactobacillus paracasei, Lactobacillus plantarum, and Pediococcus pentosaceus on the IgE-/IgG-binding ability and nutritional properties of CM are very rare. In this study, L. paracasei, L. plantarum, and P. pentosaceus fermentation on the IgE-/IgG-binding ability was determined by Enzyme-Linked Immunosorbent Assay (ELISA), and the protein quality, amino acid profile, and color were systematically evaluated. The results showed that these LAB strains exhibited higher protein degradation ability, and the IgE reactivity reduction rate was 41.03%-60.00% and the IgG reduction rate was 29.86%-67.20%, respectively. Additionally, the nutritional value was improved obviously, and the color was altered significantly, which was conductive to develop dairy products. These findings provided a theoretical foundation for the development of hypoallergenic dairy products. PRACTICAL APPLICATION: In this study, L. paracasei, L. plantarum and P. pentosaceus could be considered as good potential candidates for solving cow milk allergy owing to their decreased IgE/IgG binding ability andimproved nutritional and sensory properties, which provide a promising strategy to develop hypoallergenic dairy products.", - "journal": "Journal of food science", - "issn": [ - "1750-3841" - ], - "authors": [ - "Xiaona Liang", - "Yezhi Qu", - "Shuangping Yan", - "Jing Wang", - "Yicheng Sha", - "Meng Zhang", - "Yufei Sun", - "Xianxiang Xie", - "Huwei Song", - "Shanshan Zhao", - "Li Hu" - ], - "doi": "10.1111/1750-3841.17369", - "publishedDate": "2024-08-20T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331406", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 4 - ], - "score": 0.25, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331387", - "title": "In Situ Generation of 1-Acetylpyrene as a Visible-Light Photocatalyst for the Thia-Paternò-Büchi Reaction.", - "content": "The thia-Paternò-Büchi reaction represents one of the straightforward approaches to build thietane cores.

The highly efficient synthesis of a wide range of unprecedented thietanes from intrinsically highly unstable thiocabonyls, such as thioaldehydes and aliphatic thioketones, was made possible by the multitasking capability of pyrenacyl sulfides, as a source of thiocarbonyl substrates and as precursors of 1-acetylpyrene, which acts as the photocatalyst for the thia-Paternò-Büchi reaction.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

The second natural frequency is known to be nonlinear in temperature, and this will serve as the main focal point of this work. Cointegration is a method of normalising time series data with respect to one another - often strongly-correlated time series. Cointegration is used in this paper to remove effects from Environmental and Operational Variations, by cointegrating the first four natural frequencies for the Z24 Bridge data. The temperature effects on the natural frequency data are clearly visible within the data, and it is desirable, for the purposes of structural health monitoring, that these effects are removed. The univariate time series are embedded in higher-dimensional space, such that interesting topologies are formed. Topological data analysis is used to analyse the raw time series, and the cointegrated equivalents. A standard topological data analysis pipeline is enacted, where simplicial complexes are constructed from the embedded point clouds. Topological properties are then calculated from the simplicial complexes; such as the persistent homology.

We address this open problem by studying the Synchrony Alignment Function (SAF), which is an objective measure for the synchronization properties of a network of heterogeneous oscillators with given natural frequencies. We extend the SAF framework to analyze network-coupled oscillators with heterogeneous natural frequencies that are drawn as a multivariate random vector. Using probability theory for quadratic forms, we obtain expressions for the expectation and variance of the SAF for given network structures.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways.

In this article, a new perspective on Bayesian OMA is proposed: a Bayesian stochastic subspace identification (SSI) algorithm. Distinct from existing approaches to Bayesian OMA, a hierarchical probabilistic model is embedded at the core of covariance-driven SSI. Through substitution of canonical correlation analysis with a Bayesian equivalent, posterior distributions over the modal properties are obtained. Two inference schemes are presented for the proposed Bayesian formulation: Markov Chain Monte Carlo and variational Bayes. Two case studies are then explored. The first is benchmark study using data from a simulated, multi degree-of-freedom, linear system. Following application of Bayesian SSI, it is shown that the same posterior is targeted and recovered by both inference schemes, with good agreement between the posterior mean and the conventional SSI result. The second study applies the variational form to data obtained from an in-service structure: The Z24 bridge. The results of this study are presented at single model orders, and then using a stabilisation diagram. The recovered posterior uncertainty is presented and compared to the classic SSI result.

This review summarizes different biomass carbon structures and their preparation methods and explores the applications of these materials in electrochemical sensors. Modification of biomass carbon materials through pretreatment, physical and chemical activation, heteroatom doping, metal compound composite and other methods can make up for the deficiencies in its pore structure, electrical conductivity and surface wettability, thereby improving its electrochemical performance.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation. These findings highlight the potential of allocryptopine as a therapeutic agent for addressing neurodegenerative diseases by safeguarding neuronal health.", - "journal": "Molecular neurobiology", - "issn": [ - "1559-1182" - ], - "authors": [ - "Serap Nigdelioglu Dolanbay", - "Seda Şirin", - "Belma Aslim" - ], - "doi": "10.1007/s12035-024-04520-x", - "publishedDate": "2024-09-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331354", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "url": "https://www.ebi.ac.uk/pdbe/entry/pdb/1s5p", - "title": "Structure and substrate binding properties of cobB, a Sir2 homolog protein deacetylase from Eschericia coli.", - "content": "Structure and substrate binding properties of cobB, a Sir2 homolog protein deacetylase from Escherichia coli. - Zhao K, Chai X, Marmorstein R J Mol Biol (337) 731-41 (2004)", - "thumbnail": "https://www.ebi.ac.uk/pdbe/static/entry/1s5p_deposited_chain_front_image-200x200.png", - "engine": "pdbe", - "parsed_url": [ - "https", - "www.ebi.ac.uk", - "/pdbe/entry/pdb/1s5p", - "", - "", - "" - ], - "template": "default.html", - "engines": [ - "pdbe" - ], - "positions": [ - 10 - ], - "score": 0.1, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331317", - "title": "Psychometric properties of the Parenting Stress Index-Short Form in a Peruvian sample.", - "content": "The stress experienced by parents in fulfilling their parental role has consequences for couple dynamics, parent-child interactions, and the mental health of parents.

We mimic the periodic outbreak of HFMD over a 2-year period-with differing amplitudes-and propose a dynamic HFMD model that differentiates transmission between mature and immature individuals and uses two possible optimal-control strategies to minimize case numbers, total costs and deaths. We parameterized the model by fitting it to HFMD data in mainland China from January 2011 to December 2018, and the basic reproduction number was estimated as 0.9599. Sensitivity analysis demonstrates that transmission between immature and mature individuals contributes substantially to new infections. Increasing the isolation rates of infectious individuals-particularly mature infectious individuals-could greatly reduce the outbreak risk and potentially eradicate the disease in a relatively short time period.

This review summarizes different biomass carbon structures and their preparation methods and explores the applications of these materials in electrochemical sensors. Modification of biomass carbon materials through pretreatment, physical and chemical activation, heteroatom doping, metal compound composite and other methods can make up for the deficiencies in its pore structure, electrical conductivity and surface wettability, thereby improving its electrochemical performance. The effects of different biomass sources, functional groups, constituent elements and modification methods on the morphology, structure and electrochemical properties of biomass carbon materials are discussed, and the applications of this type of material in biological molecules, heavy metal ions and pesticide residues are reviewed.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331413", - "title": "Deterministic fabrication of graphene hexagonal boron nitride moiré superlattices.", - "content": "The electronic properties of moiré heterostructures depend sensitively on the relative orientation between layers of the stack.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

While the static sensitivity analysis focuses on the impact of network topology and update functions, the dynamic analysis accounts for context-dependent transient state distributions. To study sensitivity, we use discrete models, where each element is represented as a discrete variable and assigned an update rule, which is a function of element's known direct and indirect regulators. Our sensitivity analysis framework allows for assessing the effect of context on individual element sensitivity, as well as on element criticality in reaching preferred outcomes. The framework also enables discovery of most influential pathways in the model that are essential for satisfying important system properties, and thus, could be used for interventions. We discuss the role of nine different network attributes in identifying key elements and intervention pathways, and evaluate their performance using model checking method.

Likewise, the d/p mixing results in tunable redox properties at low potential due to the raising of the HOMO level, and making those compounds particularly suited to achieve redox switching of various properties associated to the acetylide conjugated ligand, such as photochromism, luminescence or magnetism, for charge transport at the molecular level and in field effect transistor devices, or charge storage for memory devices.

Our innovative methodology is designed for excursion sets, but is versatile enough to be applied to set-valued simulators, including those found in viability fields, or when working with maps like pollutant concentration maps or flood zone maps. We propose to use the Hilbert-Schmidt Independence Criterion (HSIC) with a kernel designed for set-valued outputs. After proposing a probabilistic framework for random sets, a first contribution is the proof that this kernel is characteristic, an essential property in a kernel-based sensitivity analysis context. To measure the contribution of each input, we then propose to use HSIC-ANOVA indices. With these indices, we can identify which inputs should be neglected (screening) and we can rank the others according to their influence (ranking). The estimation of these indices is also adapted to the set-valued outputs.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

As the evaluations of prognostic capacity, the survivals of groups with high/low expression of the biomarker are often estimated by the Kaplan-Meier method, and the difference between groups is summarized via the hazard ratio (HR). The high/low expressions are usually determined by study-specific cutoff values, which brings heterogeneity over multiple prognosis studies and difficulty to synthesizing the results in a simple way. In meta-analysis of diagnostic studies with binary outcomes, the summary receiver operating characteristics (SROC) analysis provides a useful cutoff-free summary over studies. Recently, this methodology has been extended to the time-dependent SROC analysis for time-to-event outcomes in meta-analysis of prognosis studies. In this paper, we propose a sensitivity analysis method for evaluating the impact of publication bias on the time-dependent SROC analysis. Our proposal extends the recently introduced sensitivity analysis method for meta-analysis of diagnostic studies based on the bivariate normal model on sensitivity and specificity pairs. To model the selective publication process specific to prognosis studies, we introduce a trivariate model on the time-dependent sensitivity and specificity and the log-transformed HR. Based on the proved asymptotic property of the trivariate model, we introduce a likelihood based sensitivity analysis method based on the conditional likelihood constrained by the expected proportion of published studies.

This review summarizes different biomass carbon structures and their preparation methods and explores the applications of these materials in electrochemical sensors. Modification of biomass carbon materials through pretreatment, physical and chemical activation, heteroatom doping, metal compound composite and other methods can make up for the deficiencies in its pore structure, electrical conductivity and surface wettability, thereby improving its electrochemical performance. The effects of different biomass sources, functional groups, constituent elements and modification methods on the morphology, structure and electrochemical properties of biomass carbon materials are discussed, and the applications of this type of material in biological molecules, heavy metal ions and pesticide residues are reviewed.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Cointegration is used in this paper to remove effects from Environmental and Operational Variations, by cointegrating the first four natural frequencies for the Z24 Bridge data. The temperature effects on the natural frequency data are clearly visible within the data, and it is desirable, for the purposes of structural health monitoring, that these effects are removed. The univariate time series are embedded in higher-dimensional space, such that interesting topologies are formed. Topological data analysis is used to analyse the raw time series, and the cointegrated equivalents.

Here we provide a rigorous description of the stability of various multicluster states by studying their spectral properties in the thermodynamic limit.

We address this open problem by studying the Synchrony Alignment Function (SAF), which is an objective measure for the synchronization properties of a network of heterogeneous oscillators with given natural frequencies. We extend the SAF framework to analyze network-coupled oscillators with heterogeneous natural frequencies that are drawn as a multivariate random vector. Using probability theory for quadratic forms, we obtain expressions for the expectation and variance of the SAF for given network structures.

Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation. These findings highlight the potential of allocryptopine as a therapeutic agent for addressing neurodegenerative diseases by safeguarding neuronal health.", - "journal": "Molecular neurobiology", - "issn": [ - "1559-1182" - ], - "authors": [ - "Serap Nigdelioglu Dolanbay", - "Seda Şirin", - "Belma Aslim" - ], - "doi": "10.1007/s12035-024-04520-x", - "publishedDate": "2024-09-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331354", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2408.08664v2", - "title": "A new perspective on Bayesian Operational Modal Analysis", - "publishedDate": "2024-08-16T11:11:56", - "content": "In the field of operational modal analysis (OMA), obtained modal information is frequently used to assess the current state of aerospace, mechanical, offshore and civil structures. However, the stochasticity of operational systems and the lack of forcing information can lead to inconsistent results. Quantifying the uncertainty of the recovered modal parameters through OMA is therefore of significant value. In this article, a new perspective on Bayesian OMA is proposed: a Bayesian stochastic subspace identification (SSI) algorithm. Distinct from existing approaches to Bayesian OMA, a hierarchical probabilistic model is embedded at the core of covariance-driven SSI. Through substitution of canonical correlation analysis with a Bayesian equivalent, posterior distributions over the modal properties are obtained. Two inference schemes are presented for the proposed Bayesian formulation: Markov Chain Monte Carlo and variational Bayes. Two case studies are then explored. The first is benchmark study using data from a simulated, multi degree-of-freedom, linear system. Following application of Bayesian SSI, it is shown that the same posterior is targeted and recovered by both inference schemes, with good agreement between the posterior mean and the conventional SSI result. The second study applies the variational form to data obtained from an in-service structure: The Z24 bridge. The results of this study are presented at single model orders, and then using a stabilisation diagram. The recovered posterior uncertainty is presented and compared to the classic SSI result. It is observed that the posterior distributions with mean values coinciding with the natural frequencies exhibit lower variance than values situated away from the natural frequencies.", - "doi": null, - "authors": [ - "Brandon J.

In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways. Our results indicate that allocryptopine exerts a comprehensive influence on pro-inflammatory cytokines and other inflammatory mediators by inhibiting TLR4 signaling and modulating the NF-κB and p38 MAPK pathways. The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331413", - "title": "Deterministic fabrication of graphene hexagonal boron nitride moiré superlattices.", - "content": "The electronic properties of moiré heterostructures depend sensitively on the relative orientation between layers of the stack.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

To study sensitivity, we use discrete models, where each element is represented as a discrete variable and assigned an update rule, which is a function of element's known direct and indirect regulators. Our sensitivity analysis framework allows for assessing the effect of context on individual element sensitivity, as well as on element criticality in reaching preferred outcomes. The framework also enables discovery of most influential pathways in the model that are essential for satisfying important system properties, and thus, could be used for interventions. We discuss the role of nine different network attributes in identifying key elements and intervention pathways, and evaluate their performance using model checking method. Finally, we apply our methods on the model of naive T cell differentiation, and further demonstrate the importance of context-based sensitivity analysis in identifying most influential elements and pathways.", - "doi": null, - "authors": [ - "Gaoxiang Zhou", - "Kai-Wen Liang", - "Natasa Miskov-Zivanov" - ], - "journal": null, - "tags": [ - "q-bio.MN", - "q-bio.QM" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/1902.03216v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/1902.03216v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331406", - "title": "Assessment of the effect of lactic acid bacteria fermentation on IgE-/IgG-binding ability and nutritional properties of cow milk.", - "content": "Cow milk (CM) is an important food source for humans, and food allergy caused by CM has attracted attention worldwide. To our knowledge, systematic studies about the effects of Lactobacillus paracasei, Lactobacillus plantarum, and Pediococcus pentosaceus on the IgE-/IgG-binding ability and nutritional properties of CM are very rare. In this study, L. paracasei, L. plantarum, and P. pentosaceus fermentation on the IgE-/IgG-binding ability was determined by Enzyme-Linked Immunosorbent Assay (ELISA), and the protein quality, amino acid profile, and color were systematically evaluated.

The univariate time series are embedded in higher-dimensional space, such that interesting topologies are formed. Topological data analysis is used to analyse the raw time series, and the cointegrated equivalents.

Our innovative methodology is designed for excursion sets, but is versatile enough to be applied to set-valued simulators, including those found in viability fields, or when working with maps like pollutant concentration maps or flood zone maps. We propose to use the Hilbert-Schmidt Independence Criterion (HSIC) with a kernel designed for set-valued outputs. After proposing a probabilistic framework for random sets, a first contribution is the proof that this kernel is characteristic, an essential property in a kernel-based sensitivity analysis context. To measure the contribution of each input, we then propose to use HSIC-ANOVA indices.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways.

As the evaluations of prognostic capacity, the survivals of groups with high/low expression of the biomarker are often estimated by the Kaplan-Meier method, and the difference between groups is summarized via the hazard ratio (HR). The high/low expressions are usually determined by study-specific cutoff values, which brings heterogeneity over multiple prognosis studies and difficulty to synthesizing the results in a simple way. In meta-analysis of diagnostic studies with binary outcomes, the summary receiver operating characteristics (SROC) analysis provides a useful cutoff-free summary over studies. Recently, this methodology has been extended to the time-dependent SROC analysis for time-to-event outcomes in meta-analysis of prognosis studies. In this paper, we propose a sensitivity analysis method for evaluating the impact of publication bias on the time-dependent SROC analysis. Our proposal extends the recently introduced sensitivity analysis method for meta-analysis of diagnostic studies based on the bivariate normal model on sensitivity and specificity pairs. To model the selective publication process specific to prognosis studies, we introduce a trivariate model on the time-dependent sensitivity and specificity and the log-transformed HR. Based on the proved asymptotic property of the trivariate model, we introduce a likelihood based sensitivity analysis method based on the conditional likelihood constrained by the expected proportion of published studies.

This review summarizes different biomass carbon structures and their preparation methods and explores the applications of these materials in electrochemical sensors. Modification of biomass carbon materials through pretreatment, physical and chemical activation, heteroatom doping, metal compound composite and other methods can make up for the deficiencies in its pore structure, electrical conductivity and surface wettability, thereby improving its electrochemical performance. The effects of different biomass sources, functional groups, constituent elements and modification methods on the morphology, structure and electrochemical properties of biomass carbon materials are discussed, and the applications of this type of material in biological molecules, heavy metal ions and pesticide residues are reviewed.

In such cases, a sensitivity analysis is often conducted, which investigates whether the observed association between treatment and outcome is due to effects caused by the treatment or it is due to hidden confounding. In general, a sensitivity analysis tries to infer the minimum amount of hidden biases needed in order to explain away the observed association between treatment and outcome, assuming that the treatment has no effect. If the needed bias is large, then the treatment is likely to have significant effects. The Rosenbaum sensitivity analysis is a modern approach for conducting sensitivity analysis for matched observational studies. It investigates what magnitude the maximum of the hidden biases from all matched sets needs to be in order to explain away the observed association, assuming that the treatment has no effect. However, such a sensitivity analysis can be overly conservative and pessimistic, especially when the investigators believe that some matched sets may have exceptionally large hidden biases. In this paper, we generalize Rosenbaum's framework to conduct sensitivity analysis on quantiles of hidden biases from all matched sets, which are more robust than the maximum. Moreover, we demonstrate that the proposed sensitivity analysis on all quantiles of hidden biases is simultaneously valid and is thus a free lunch added to the conventional sensitivity analysis. The proposed approach works for general outcomes, general matched studies and general test statistics. Finally, we demonstrate that the proposed sensitivity analysis also works for bounded null hypotheses as long as the test statistic satisfies certain properties.

However, inherent limitations, such as adaptability, adhesion, and conductivity, have presented challenges, thereby limiting the sensitivity, signal-to-noise ratio (SNR), and stability of the physiological-electrode interface. In this study, we propose the concept of myelin sheath-inspired hydrogel epidermal electronics by incorporating numerous interpenetrating core-sheath-structured conductive nanofibers within a physically cross-linked polyelectrolyte network. Poly(3,4-ethylenedioxythiophene)-coated sulfonated cellulose nanofibers (PEDOT:SCNFs) are synthesized through a simple solvent-catalyzed sulfonation process, followed by oxidative self-polymerization and ionic liquid (IL) shielding steps, achieving a low electrochemical impedance of 42 Ω. The physical associations within the composite hydrogel network include complexation, electrostatic forces, hydrogen bonding, π-π stacking, hydrophobic interaction, and weak entanglements. These properties confer the hydrogel with high stretchability (770%), superconformability, self-adhesion (28 kPa on pigskin), and self-healing capabilities. By simulating the saltatory propagation effect of the nodes of Ranvier in the nervous system, the biomimetic hydrogel establishes high-fidelity epidermal electronic interfaces, offering benefits such as low interfacial contact impedance, significantly increased SNR (30 dB), as well as large-scale sensor array integration.

Unlike the binary treatment case, although widely needed in practice, sensitivity analysis for matched observational studies with treatment doses (i.e., non-binary treatments such as ordinal treatments or continuous treatments) still lacks solid foundations and valid methodologies. We fill in this blank by establishing theoretical foundations and novel methodologies under a generalized Rosenbaum bounds sensitivity analysis framework. First, we present a criterion for assessing the validity of sensitivity analysis in matched observational studies with treatment doses and use that criterion to justify the necessity of incorporating the treatment dose information into sensitivity analysis through generalized Rosenbaum sensitivity bounds. We also generalize Rosenbaum's classic sensitivity parameter $\\Gamma$ to the non-binary treatment case and prove its sufficiency. Second, we study the asymptotic properties of sensitivity analysis by generalizing Rosenbaum's classic design sensitivity and Bahadur efficiency for testing Fisher's sharp null to the non-binary treatment case and deriving novel formulas for them. Our theoretical results showed the importance of appropriately incorporating the treatment dose into a test, which is an intrinsic distinction with the binary treatment case. Third, for testing Neyman's weak null (i.e., null sample average treatment effect), we propose the first valid sensitivity analysis procedure for matching with treatment dose through generalizing an existing optimization-based sensitivity analysis for the binary treatment case, built on the generalized Rosenbaum sensitivity bounds and large-scale mixed integer programming.", - "doi": null, - "authors": [ - "Siyu Heng", - "Hyunseung Kang" - ], - "journal": null, - "tags": [ - "stat.ME", - "math.ST", - "stat.TH" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2403.14152v2", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2403.14152v2", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331413", - "title": "Deterministic fabrication of graphene hexagonal boron nitride moiré superlattices.", - "content": "The electronic properties of moiré heterostructures depend sensitively on the relative orientation between layers of the stack.

To create samples with aligned graphene/hBN, researchers often align edges of exfoliated flakes that appear straight in optical micrographs. However, graphene or hBN can cleave along either zig-zag or armchair lattice directions, introducing a [Formula: see text] ambiguity in the relative orientation of two flakes. By characterizing the crystal lattice orientation of exfoliated flakes prior to stacking using Raman and second-harmonic generation for graphene and hBN, respectively, we unambiguously align monolayer graphene to hBN at a near-[Formula: see text], not [Formula: see text], relative twist angle. We confirm this alignment by torsional force microscopy of the graphene/hBN moiré on an open-face stack, and then by cryogenic transport measurements, after full encapsulation with a second, nonaligned hBN layer.

While the static sensitivity analysis focuses on the impact of network topology and update functions, the dynamic analysis accounts for context-dependent transient state distributions. To study sensitivity, we use discrete models, where each element is represented as a discrete variable and assigned an update rule, which is a function of element's known direct and indirect regulators. Our sensitivity analysis framework allows for assessing the effect of context on individual element sensitivity, as well as on element criticality in reaching preferred outcomes. The framework also enables discovery of most influential pathways in the model that are essential for satisfying important system properties, and thus, could be used for interventions. We discuss the role of nine different network attributes in identifying key elements and intervention pathways, and evaluate their performance using model checking method.

The second natural frequency is known to be nonlinear in temperature, and this will serve as the main focal point of this work. Cointegration is a method of normalising time series data with respect to one another - often strongly-correlated time series. Cointegration is used in this paper to remove effects from Environmental and Operational Variations, by cointegrating the first four natural frequencies for the Z24 Bridge data. The temperature effects on the natural frequency data are clearly visible within the data, and it is desirable, for the purposes of structural health monitoring, that these effects are removed. The univariate time series are embedded in higher-dimensional space, such that interesting topologies are formed. Topological data analysis is used to analyse the raw time series, and the cointegrated equivalents.

This study aims to investigate the antioxidant and anti-inflammatory effects of allocryptopine on various targets and potential mechanisms that have not been previously explored in the literature. Initially, we used MTT and LDH methods to evaluate the effects of allocryptopine on cell viability in BV-2 cells exposed to LPS-induced damage. Subsequently, we evaluated the impact of allocryptopine on pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), other inflammatory mediators (Cox-2 and iNOS), and p38 MAPK genes and proteins through qRT-PCR and Western blot analyses. Also, we evaluated the impact of allocryptopine on NF-κB proteins (TLR4, MyD88, IκBα, p-p50, and p-p65) through ELISA assay. Molecular docking analyses were performed to investigate the potential binding of allocryptopine to target proteins (TLR4, MyD88, IκBα, p50, p65, MKK3, MKK4, MKK6, p38, AP-1 (c-Jun and ATF2), IL-1β, IL-6, TNF-α, Cox-2, and iNOS) associated with the TLR4, NF-κB, and p38 MAPK pathways.

The outcomes of our study suggest that the antioxidant and anti-inflammatory efficacy of allocryptopine is intricately linked to the modulation of key molecular pathways associated with oxidative stress and inflammation.

As the evaluations of prognostic capacity, the survivals of groups with high/low expression of the biomarker are often estimated by the Kaplan-Meier method, and the difference between groups is summarized via the hazard ratio (HR). The high/low expressions are usually determined by study-specific cutoff values, which brings heterogeneity over multiple prognosis studies and difficulty to synthesizing the results in a simple way. In meta-analysis of diagnostic studies with binary outcomes, the summary receiver operating characteristics (SROC) analysis provides a useful cutoff-free summary over studies. Recently, this methodology has been extended to the time-dependent SROC analysis for time-to-event outcomes in meta-analysis of prognosis studies. In this paper, we propose a sensitivity analysis method for evaluating the impact of publication bias on the time-dependent SROC analysis. Our proposal extends the recently introduced sensitivity analysis method for meta-analysis of diagnostic studies based on the bivariate normal model on sensitivity and specificity pairs. To model the selective publication process specific to prognosis studies, we introduce a trivariate model on the time-dependent sensitivity and specificity and the log-transformed HR. Based on the proved asymptotic property of the trivariate model, we introduce a likelihood based sensitivity analysis method based on the conditional likelihood constrained by the expected proportion of published studies.

It is indeed known that the convection of vortical structures across a grid refinement interface, where cell size is abruptly doubled, is likely to generate spurious noise that may corrupt the solution over the whole computational domain. This issue becomes critical in the case of aeroacoustic simulations, where accurate pressure estimations are of paramount importance. Consequently, any interfering noise that may pollute the acoustic predictions must be reduced. The proposed grid refinement algorithm differs from conventionally used ones, in which an overlapping mesh layer is considered. Instead, it provides a direct connection allowing a tighter link between fine and coarse grids, especially with the use of a coherent equilibrium function shared by both grids. Moreover, the direct coupling makes the algorithm more local and prevents the duplication of points, which might be detrimental for massive parallelization.

The Si-IGBT switch-based converters are inefficient, oversized, and have trouble achieving pure sine wave voltages requirements. The efficiency of the aircraft ground power units (AGPU) can be increased by replacing existing Si-IGBT transistors with silicon carbide (SiC) IGBTs because of the physical constraints of Si-IGBT switches. The primary purpose of this research was to prove that the efficiency increase could be obtained in the case of using SiC-IGBTs in conventional AGPU systems with the realized experimental studies. In this study, three different experimental systems were discussed for this purpose. The first system was the traditional APGU system. The other two systems were single-phase test (SPT) and three-phase inverter systems, respectively. The SPT system and three-phase inverter systems were designed and implemented to compare and make analyses of Si-IGBTs and SiC-IGBTs performance. The efficiency and detailed hard switching behavior comparison were performed between the 1200-V SiC-IGBT- and 1200-V Si-IGBT-based experimental systems. The APGU system and Si-IGBT modules were examined, the switching characteristic and efficiency of the system were obtained in the first experimental study. The second experimental study was carried out on the SPT system. The single-pulse test system was created using Si-IGBTs and SiC-IGBTs switches in the second experimental system. The third experiment included a three-phase-inverter-based test system. The system was created with Si-IGBTs and SiC-IGBTs to compare the two different switch-based inverters under RL loads. The turning off and turning on processes of the IGBT switches were examined and the results were presented. The Si-IGBT efficiency was 77% experimentally in the SPT experimental system. The efficiency of the third experimental system was increased up to 95% by replacing the old Si transistor with a SiC. The efficiency of the three-phase Si-IGBT-based system was 86% for the six-switch case. The efficiencies of the SiC-IGBT-based system were increased to around 92% in the three-phase inverter system experimentally. The findings of the experimental results demonstrated that the SiC-IGBT had a faster switching speed and a smaller loss than the classical Si-IGBT. As a result of the experimental studies, the efficiency increase that could be obtained in the case of using SiC-IGBTs in conventional AGPU systems was revealed.", - "journal": "Micromachines", - "issn": [ - "2072-666X" - ], - "authors": [ - "Ibrahim A S Abdalgader", - "Sinan Kivrak", - "Tolga Özer" - ], - "doi": "10.3390/mi13020313", - "publishedDate": "2022-02-04T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/35208437", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/34890853", - "title": "A predictive model of organic acids separation by chromatography with strong anionic resins in sulfate form.", - "content": "Organic acids commonly have quite symmetrical chromatography profiles at low pH (< 1.5) with strong anionic resins, but a significant tailing can be observed with succinic and citric acids. Classical adsorption models, like the Langmuir model, fail to predict this behavior, which can have a major influence on mean retention times and profile shapes, therefore on chromatography performances. A new retention model was developed to better predict organic acid separation with strong anionic resin. This model combines a refined Langmuir adsorption model and an ion-exchange model. Organic acid adsorption is assumed to be due to hydrogen bonding with sulfate and hydrogen sulfate counter-anions on the resin. The adsorption capacity depends mostly on molecular size: up to sixteen formic acid molecules could be adsorbed per counter-anions, meanwhile only two succinic acid or one citric acid molecules could be adsorbed. This adsorption model was then embedded in a generic and accurate modeling approach (continuous column with mass balance equations solved by the conservation element/solution element (CE/SE) method). All parameters of this column model were identified by fitting the simulation to experimental results (equilibrium curves and pulse tests). Then, the column model was validated with original experimental results from a binary mixture pulse test (formic and succinic acids). Results show that simulations are much more predictive for multi-component pulse tests, both in terms of profile shape and retention time, which cannot be captured without considering ion-exchange.", - "journal": "Journal of chromatography.

The key part of the system called gyrotron is driven by a high voltage power supply with a rated output power of hundreds of kilowatts. When the system is in operation, breakdowns frequently occur in the gyrotron. During breakdowns, the gyrotron will endure a large volume of energy and may be damaged. A solid-state switch is required to protect it by blocking high voltage (∼40 kV) within 10 microseconds and limiting energy within a few joules. Compared with Si IGBT/MOSFET, SiC MOSFET with higher switching speed is more suitable for the switch. However, rapid switching speed exacerbates the voltage imbalance. To solve the problems, a reliable module named Advanced Chopper Sub-Model based on SiC MOSFETs for a solid-state switch is proposed. The module adopts a voltage-clamped circuit to achieve the capabilities of rapid switching-off speed, as well as low overvoltage and good voltage balancing. In addition, modules connected in series can tolerate large driver time delay. The SPICE simulation and the double-pulse test are used to validate the effectiveness of the proposed module. The protection performance test was also conducted by using a spark gap to simulate the breakdown fault. Finally, the switch that consists of 64 series-connected modules has been tested at 30 kV/6 A.

A key regulator of motor output is the balance between excitation and inhibition in the primary motor cortex, which can be assessed in humans with transcranial magnetic stimulation techniques. Despite decades of research, the functional state of cortical inhibition in Parkinson's disease remains uncertain. Towards resolving this issue, we applied paired-pulse transcranial magnetic stimulation protocols in 166 patients with Parkinson's disease (57 levodopa-naïve, 50 non-dyskinetic, 59 dyskinetic) and 40 healthy controls (age-matched with the levodopa-naïve group). All patients were studied OFF medication. All analyses were performed with fully automatic procedures to avoid confirmation bias, and we systematically considered and excluded several potential confounding factors such as age, gender, resting motor threshold, EMG background activity and amplitude of the motor evoked potential elicited by the single-pulse test stimuli. Our results show that short-interval intracortical inhibition is decreased in Parkinson's disease compared to controls. This reduction of intracortical inhibition was obtained with relatively low-intensity conditioning stimuli (80% of the resting motor threshold) and was not associated with any significant increase in short-interval intracortical facilitation or intracortical facilitation with the same low-intensity conditioning stimuli, supporting the involvement of cortical inhibitory circuits. Short-interval intracortical inhibition was similarly reduced in levodopa-naïve, non-dyskinetic and dyskinetic patients. Importantly, intracortical inhibition was reduced compared to control subjects also on the less affected side (n = 145), even in de novo drug-naïve patients in whom the less affected side was minimally symptomatic (lateralized Unified Parkinson's Disease Rating Scale part III = 0 or 1, n = 23).

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs. Each DSB could use three potential intact homologous DNA sequences as repair template: one from the sister chromatid and the two others from the homologous chromosomes.", - "journal": "Plant reproduction", - "issn": [ - "2194-7961" - ], - "authors": [ - "Nahid Rafiei", - "Arnaud Ronceret" - ], - "doi": "10.1007/s00497-024-00509-7", - "publishedDate": "2024-08-26T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331138", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2211.00799v1", - "title": "Practical Phase Retrieval Using Double Deep Image Priors", - "publishedDate": "2022-11-02T00:37:51", - "content": "Phase retrieval (PR) concerns the recovery of complex phases from complex magnitudes.

We find that apart from the additional noise associated with the parametric amplification process noticed by others, the stability condition for the entire system poses an additional constraint.

This bias reflects asymmetric dopamine (DA) signaling in the striatum. Administration of DA agonists reduces spatial bias, yet the underlying mechanism is not yet clear. To address this, the current study tested whether methylphenidate (MPH; an indirect DA agonist) reduces orienting bias by modulating fronto-striatal connectivity. 54 adults with consistent bias completed the greyscales task which detects subtle biases during fMRI scanning under MPH (20 mg) or placebo, in a double-blind design. As hypothesized, MPH reduced bias by increasing orienting towards non-preferred hemispace, regardless of whether the initial bias was left or right. MPH-induced increases were found in activation of the medial superior frontal gyrus (mSFG: F[1;53] = 4.632, cluster-defining threshold of P < 0.05, minimal cluster size = 0, p_FWE = 0.036, η2 = 0.08) and its functional connectivity with the caudate (left caudate: F[1;53] = 12.664, p_FWE = 0.001, η2 = 0.192; right caudate: F[1;53] = 11.069, p_FWE = 0.002, η2 = 0.172), when orienting towards the non-preferred hemispace.

Nevertheless, the anodic oxygen evolution reaction (OER) constitutes a substantial obstacle to the large-scale deployment of this technology, due to the considerable overpotential resulting from the retardation kinetics associated with the OER. The development of low-cost, high-activity, and long-lasting OER catalysts has emerged as a pivotal research area. Layered double hydroxides (LDHs) have garnered significant attention due to their suitability for use with base metals, which are cost-effective and exhibit enhanced activity. However, the current performance of LDHs OER catalysts is still far from meeting the demands of industrial applications, particularly in terms of their long-term stability. In this review, we provide an overview of the causes for the deactivation of LDHs OER catalysts and present an analysis of the various mechanisms employed to improve the stability of these catalysts, including the synthesis of LDH ultrathin nanosheets, adjustment of components and doping, dissolution and redeposition, defect creation and corrosion, and utilization of advanced carbon materials.", - "journal": "Nanomaterials (Basel, Switzerland)", - "issn": [ - "2079-4991" - ], - "authors": [ - "Lielie He", - "Yangen Zhou", - "Mengran Wang", - "Simin Li", - "Yanqing Lai" - ], - "doi": "10.3390/nano14181533", - "publishedDate": "2024-09-19T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330689", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2010.13346v1", - "title": "Energy and Service-priority aware Trajectory Design for UAV-BSs using Double Q-Learning", - "publishedDate": "2020-10-26T05:21:30", - "content": "Next-generation mobile networks have proposed the integration of Unmanned Aerial Vehicles (UAVs) as aerial base stations (UAV-BS) to serve ground nodes.

Poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is commonly used as a hole transport layer (HTL) in the inverted PSCs to achieve efficient and stable performance. However, PEDOT:PSS can corrode ITO, affecting device efficiency. Moreover, the hydrophilic nature of PEDOT:PSS compromises device stability. In this work, Poly (3-hexylthiophene-2,5-diyl) (P3HT), known for its good hydrophobicity, was used to modify the surface of PEDOT:PSS, reducing its water absorption and thereby enhancing the efficiency and stability of PSCs. The results reveal that incorporating P3HT effectively enhances the hydrophobicity of PEDOT:PSS. Furthermore, it fosters the development of large-grain perovskite film on the PEDOT:PSS/P3HT bilayer. This enhancement leads to a power conversion efficiency (PCE) of 19.78% for PSCs, with an increase by 16% than that of reference cells (17.04% of PCE). Following a duration of 1000 h, the PCE for the device modified with P3HT remains above 90%, while the PCE of the reference device is below 70%. These findings suggest that using P3HT in conjunction with PEDOT:PSS as a bilayer HTL can concurrently and proficiently improve the efficiency and stability of PSCs.", - "journal": "Nanomaterials (Basel, Switzerland)", - "issn": [ - "2079-4991" - ], - "authors": [ - "Xiude Yang", - "Minghao Luo", - "Qianqian Zhang", - "Haishen Huang", - "Yanqing Yao", - "Yuanlin Yang", - "Ying Li", - "Wan Cheng", - "Ping Li" - ], - "doi": "10.3390/nano14181476", - "publishedDate": "2024-09-06T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330634", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2101.06452v1", - "title": "Hyperfine measurement of $6\\text{P}_{1/2}$ state in $^{87}\\text{Rb}$ using double resonance on blue and IR transition", - "publishedDate": "2021-01-16T14:58:15", - "content": "In this paper, we present the spectroscopy of 6P$_{1/2}$ state in $^{87}$Rb using double resonance technique at $780~\\text{nm}$ and $421~\\text{nm}$.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface.

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

However, PEDOT:PSS can corrode ITO, affecting device efficiency. Moreover, the hydrophilic nature of PEDOT:PSS compromises device stability. In this work, Poly (3-hexylthiophene-2,5-diyl) (P3HT), known for its good hydrophobicity, was used to modify the surface of PEDOT:PSS, reducing its water absorption and thereby enhancing the efficiency and stability of PSCs. The results reveal that incorporating P3HT effectively enhances the hydrophobicity of PEDOT:PSS. Furthermore, it fosters the development of large-grain perovskite film on the PEDOT:PSS/P3HT bilayer. This enhancement leads to a power conversion efficiency (PCE) of 19.78% for PSCs, with an increase by 16% than that of reference cells (17.04% of PCE). Following a duration of 1000 h, the PCE for the device modified with P3HT remains above 90%, while the PCE of the reference device is below 70%.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results. Thus, we conclude that scattering induced by a high density of electric dipoles at the interface is dominant cause of the low mobility in SiC MOSFETs.", - "doi": "10.1063/5.0086172", - "authors": [ - "Tetsuo Hatakeyama", - "Hirohisa Hirai", - "Mitsuru Simetani", - "Dai Okamoto", - "Mitsuo Okamoto", - "Shinsuke Harada" - ], - "journal": null, - "tags": [ - "physics.app-ph" - ], - "comments": "16pages, 3 figures", - "pdf_url": "http://arxiv.org/pdf/2201.03821v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2201.03821v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331418", - "title": "Hydrophobic ZIF-8 nanoparticles loaded on chitosan for improved methanol adsorption from fermented wine.", - "content": "Metal-organic frameworks (MOFs) have great potential for the adsorption of minor molecular alcohols in the vapor phase.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals. Thus, the cable and motor surge impedances can be matched over a short time to prevent reflected waves. As a result, the leakage currents passing through the ball bearing and overvoltage stress on the motor insulation can be suppressed significantly.", - "doi": null, - "authors": [ - "Fahmid Sadeque", - "Fariba Fateh", - "JiangBiao He", - "Behrooz Mirafzal" - ], - "journal": null, - "tags": [ - "eess.SY", - "cs.SY" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2212.13211v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2212.13211v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 6 - ], - "score": 0.16666666666666666, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331382", - "title": "Modular Synthesis of Azidobicyclo[2.1.1]hexanes via (3 + 2) Annulation of α-Substituted Vinyl Azides and Bicyclo[1.1.0]butanes.", - "content": "Here, we present a mild and rapid method to access azidobicyclo[2.1.1]hexanes via formal (3 + 2) cycloaddition of α-substituted vinyl azides and bicyclo[1.1.0]butanes under Lewis acid catalysis.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance. Since commercial SiC MOSFETs are capable of operating in a wide range of temperatures, it is important to know the values of ITCs in the whole temperature range of operation. Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances. In addition, it is shown that at high frequencies stray inductances of the TO-247-3 package result in a change of the extracted values of the on-state ITCs.

The electro-thermal simulation calculates the junction temperature and updates the temperature-related parameters with the proposed loss model and the thermal network model. A multi-rate data exchange strategy is proposed to solve the problem of disparity in timescales between circuit simulation and thermal network simulation. The CREE CMF20120D SiC MOSFET device is used for the experimental verification. The experimental results verify the accuracy of the model which provides guidance for the circuit design of SiC MOSFETs.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results. Thus, we conclude that scattering induced by a high density of electric dipoles at the interface is dominant cause of the low mobility in SiC MOSFETs.", - "doi": "10.1063/5.0086172", - "authors": [ - "Tetsuo Hatakeyama", - "Hirohisa Hirai", - "Mitsuru Simetani", - "Dai Okamoto", - "Mitsuo Okamoto", - "Shinsuke Harada" - ], - "journal": null, - "tags": [ - "physics.app-ph" - ], - "comments": "16pages, 3 figures", - "pdf_url": "http://arxiv.org/pdf/2201.03821v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2201.03821v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 3 - ], - "score": 0.3333333333333333, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331193", - "title": "Exploring the heterogeneity of interstitial cells of Cajal and their properties in gastrointestinal mesenchymal tumors applying single-cell RNA sequencing analysis.", - "content": "Gastrointestinal mesenchymal stromal tumors (GISTs) are a group of intramural tumors that exhibit a wide range of morphologies.

A separate examination of the photons emitted at the rising and falling transitions of the gate-source voltage enabled the extraction of two different spectral components.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance. Since commercial SiC MOSFETs are capable of operating in a wide range of temperatures, it is important to know the values of ITCs in the whole temperature range of operation. Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

In this study, we designed PEG hydrogels with enhanced hydrophobicity through gel-gel phase separation (GGPS), a phenomenon that uniquely enhances hydrophobicity under ambient conditions, and we elucidated the pivotal role of elasticity in this process. We hypothesized that increased elasticity would amplify GGPS, thereby improving the hydrophobicity and cell adhesion on PEG hydrogel surfaces, despite their inherent hydrophilicity. To test this hypothesis, we engineered dilute oligo-PEG gels via a two-step process, creating polymer networks from tetra-PEG clusters with multiple reaction points. These oligo-PEG gels exhibited significantly higher elasticity, turbidity, and shrinkage upon water immersion compared to dilute PEG gels. Detailed characterization through confocal laser scanning microscopy, rheological measurements, and cell adhesion assays revealed distinct biphasic structures, increased hydrophobicity, and enhanced cell attachability in the dilute oligo-PEG gels.

However, the most critical challenge to the commercialization of Ga$_2$O$_3$ electronics is overheating, which impacts the device's performance and reliability. We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs. This LT approach is essential to preserve the structural integrity of the composite wafer. These LT-grown epitaxial Ga$_2$O$_3$ MOSFETs deliver high thermal performance (56% reduction in channel temperature), high voltage blocking capabilities up to 2.45 kV, and power figures of merit of $\\sim$ 300 MW/cm$^2$, which is a record high for any heterogeneously integrated Ga$_2$O$_3$ devices reported to date. This work is the first realization of multi-kilovolt homoepitaxial Ga$_2$O$_3$ power MOSFETs fabricated on a composite substrate with high heat transfer performance which delivers state-of-the-art power density values while running much cooler than those on native substrates. Thermal characterization and modeling results reveal that a Ga$_2$O$_3$/diamond composite wafer with a reduced Ga$_2$O$_3$ thickness ($\\sim$ 1 $\\mu$m) and thinner bonding interlayer ($<$ 10 nm) can reduce the device thermal impedance to a level lower than today's GaN-on-SiC power switches.", - "doi": null, - "authors": [ - "Yiwen Song", - "Arkka Bhattacharyya", - "Anwarul Karim", - "Daniel Shoemaker", - "Hsien-Lien Huang", - "Saurav Roy", - "Craig McGray", - "Jacob H.

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs. Each DSB could use three potential intact homologous DNA sequences as repair template: one from the sister chromatid and the two others from the homologous chromosomes.", - "journal": "Plant reproduction", - "issn": [ - "2194-7961" - ], - "authors": [ - "Nahid Rafiei", - "Arnaud Ronceret" - ], - "doi": "10.1007/s00497-024-00509-7", - "publishedDate": "2024-08-26T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331138", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2406.08701v1", - "title": "Impacts of Backside Insulation on the Dynamic On-Resistance of Lateral p-GaN HEMTs-on-Si", - "publishedDate": "2024-06-12T23:58:41", - "content": "We examined the effect of backside insulation on the dynamic on-resistance of lateral p-GaN HEMTs.

Results through Sentaurus TCAD simulation suggest that the use of backside insulation in devices gradually disperses potential to the buffer barrier.

However, the current performance of LDHs OER catalysts is still far from meeting the demands of industrial applications, particularly in terms of their long-term stability. In this review, we provide an overview of the causes for the deactivation of LDHs OER catalysts and present an analysis of the various mechanisms employed to improve the stability of these catalysts, including the synthesis of LDH ultrathin nanosheets, adjustment of components and doping, dissolution and redeposition, defect creation and corrosion, and utilization of advanced carbon materials.", - "journal": "Nanomaterials (Basel, Switzerland)", - "issn": [ - "2079-4991" - ], - "authors": [ - "Lielie He", - "Yangen Zhou", - "Mengran Wang", - "Simin Li", - "Yanqing Lai" - ], - "doi": "10.3390/nano14181533", - "publishedDate": "2024-09-19T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330689", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2008.11928v3", - "title": "Quantum illumination receiver using double homodyne detection", - "publishedDate": "2020-08-27T06:15:00", - "content": "A quantum receiver is an essential element of quantum illumination (QI) which outperforms its classical counterpart, called classical-illumination (CI). However, there are only few proposals for realizable quantum receiver, which exploits nonlinear effects leading to increasing the complexity of receiver setups. To compensate this, in this article, we design a quantum receiver with linear optical elements for Gaussian QI. Rather than exploiting nonlinear effect, our receiver consists of a 50:50 beam splitter and homodyne detection. Using double homodyne detection after the 50:50 beam splitter, we analyze the performance of the QI in different regimes of target reflectivity, source power, and noise level. We show that our receiver has better signal-to-noise ratio and more robust against noise than the existing simple-structured receivers.", - "doi": "10.1103/PhysRevResearch.3.013006", - "authors": [ - "Yonggi Jo", - "Sangkyung Lee", - "Yong Sup Ihn", - "Zaeill Kim", - "Su-Yong Lee" - ], - "journal": "Phys.

Poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is commonly used as a hole transport layer (HTL) in the inverted PSCs to achieve efficient and stable performance. However, PEDOT:PSS can corrode ITO, affecting device efficiency. Moreover, the hydrophilic nature of PEDOT:PSS compromises device stability. In this work, Poly (3-hexylthiophene-2,5-diyl) (P3HT), known for its good hydrophobicity, was used to modify the surface of PEDOT:PSS, reducing its water absorption and thereby enhancing the efficiency and stability of PSCs. The results reveal that incorporating P3HT effectively enhances the hydrophobicity of PEDOT:PSS. Furthermore, it fosters the development of large-grain perovskite film on the PEDOT:PSS/P3HT bilayer. This enhancement leads to a power conversion efficiency (PCE) of 19.78% for PSCs, with an increase by 16% than that of reference cells (17.04% of PCE). Following a duration of 1000 h, the PCE for the device modified with P3HT remains above 90%, while the PCE of the reference device is below 70%. These findings suggest that using P3HT in conjunction with PEDOT:PSS as a bilayer HTL can concurrently and proficiently improve the efficiency and stability of PSCs.", - "journal": "Nanomaterials (Basel, Switzerland)", - "issn": [ - "2079-4991" - ], - "authors": [ - "Xiude Yang", - "Minghao Luo", - "Qianqian Zhang", - "Haishen Huang", - "Yanqing Yao", - "Yuanlin Yang", - "Ying Li", - "Wan Cheng", - "Ping Li" - ], - "doi": "10.3390/nano14181476", - "publishedDate": "2024-09-06T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330634", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2010.13346v1", - "title": "Energy and Service-priority aware Trajectory Design for UAV-BSs using Double Q-Learning", - "publishedDate": "2020-10-26T05:21:30", - "content": "Next-generation mobile networks have proposed the integration of Unmanned Aerial Vehicles (UAVs) as aerial base stations (UAV-BS) to serve ground nodes.

In this paper, we present an energy-efficient trajectory optimization for a UAV assisted IoT system in which the UAV-BS considers the IoT nodes' service priorities in making its movement decisions.

Kaczmarz method is a stochastic method for solving overdetermined linear systems based on a sampling of matrix rows. The standard approach to speed up convergence of iterative methods is using preconditioner. As we show the best possible preconditioner for this method can be constructed from QR decomposition of the system matrix, but the complexity of this procedure is too high.

Moreover, the iteration matrices can be stored in the image reconstruction devices, which enables the Kaczmarz method and the symmetric Kaczmarz method to be used like the simultaneous iterative reconstructive techniques (SIRT).

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

Cattle are recognized as the primary animal reservoir of STEC. This study reports the occurrence and characterization of STEC from dairy cows and evaluates the inhibition of adherence by catlle anti-STEC antibodies to the HEp-2 cell. From 151 samples, 30% (n = 45) were positive for stx by PCR screening (25.21% of dairy cows and 46.8% of growing calves). From these positive samples, 17 STEC isolates were characterized. In dairy cows, 3 out of 17 samples carried stx2, 3 out of 17 possessed stx1, and 2 out of 17 carried stx1/stx2. In growing cows, 8 out of 17 samples carried stx1 and 1 out of 17 carried stx1/stx2. Other virulence factors such as ehxA, saa, iha, cah, and eae were detected. The strains were typed into 3 E. coli O groups (O26, O91, and O130). The analysis of the HEp-2 adherence assays indicated that all serum from both cattle categories presented high levels of inhibition of adherence. Considering the severity of the symptoms caused by STEC in humans, searching for factors influencing the colonization of STEC in cattle would help identify strategies to avoid transmission and STEC infection.", - "journal": "Veterinary research communications", - "issn": [ - "1573-7446" - ], - "authors": [ - "Rocío Colello", - "M Victoria Vélez", - "Marcelo Rodríguez", - "Ariel Rogé", - "Analía I Etcheverría", - "Nora Lía Padola" - ], - "doi": "10.1007/s11259-024-10557-z", - "publishedDate": "2024-09-21T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331343", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331330", - "title": "Production, Characterization, Kinetics, and Thermodynamics Analysis of Amyloglucosidase from Fungal Consortium.", - "content": "The current study aimed to produce an amyloglucosidase enzyme from the fungal consortium.

Also, the population structure analysis of LSDVs was carried out. Out of 138 scab samples tested from suspected cattle for LSDV, 106 were found positive. Of these, nine representative scab samples were further genetically characterized. Phylogenetic analysis based on the P32 and EEV gene sequences depicted that the LSDV strains of the present study had nucleotide identity of 100% and 99.10-99.45%, respectively with the LSDV/2019 field strains of India. Multiple sequence alignment of the EEV glycoprotein gene sequences revealed nucleotide polymorphisms at three positions viz., G178A, G253A and A459G in circulating LSDV/2022 field strains. Based on the median joining network analysis of the EEV gene, 12 haplotypes were identified among the LSDV populations. Population structure analysis corresponding to the EEV gene revealed high haplotype (0.8486 ± 0.026) and low nucleotide diversities (0.00636 ± 0.0006) and negative values for neutrality indices, indicating a high number of closely related haplotypes and the studied population may have undergone a recent expansion.

Various spectroscopic techniques were used to characterize the synthesized NPs. In the FT-IR spectra, peaks obtained at 504 cm-1 to 600 cm-1 were due to Cu-O vibrations. The energy dispersive X-ray analysis (EDX) spectra confirmed the CuO NPs' composition and B's presence inside the NPs. The peak pattern in X-ray diffraction (XRD) spectrum confirmed the crystalline and monoclinic phases of the NPs. The average crystalline size of CuO NPs and B-CuO NPs was 19.56 nm and 17.30 nm respectively. The CuO and B-CuO NPs were tested against three Gram-positive bacterial strains namely Bacillus subtilis, Micrococcus luteus, and Staphylococcus aureus and three Gram-negative Escherichia coli, Salmonella abony, and Pseudomonas aeruginosa through Agar well diffusion method and it was found that CuO NPs showed higher activity than B-CuO NPs.", - "journal": "Chemistry & biodiversity", - "issn": [ - "1612-1880" - ], - "authors": [ - "Ekhlakh Veg", - "Azam Raza", - "Smita Rai", - "Swati Sharma", - "Anushka Pandey", - "Mohammad Imran Ahmad", - "Sabeeha Jabeena", - "Seema Joshi", - "Tahmeena Khan" - ], - "doi": "10.1002/cbdv.202401596", - "publishedDate": "2024-09-27T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330976", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39330972", - "title": "Gel-Gel Phase Separation in Clustered Poly(ethylene glycol) Hydrogel with Enhanced Hydrophobicity.", - "content": "The development of hydrophobic poly(ethylene glycol) (PEG) hydrogels, which are typically hydrophilic, could significantly enhance their application as artificial extracellular matrices. In this study, we designed PEG hydrogels with enhanced hydrophobicity through gel-gel phase separation (GGPS), a phenomenon that uniquely enhances hydrophobicity under ambient conditions, and we elucidated the pivotal role of elasticity in this process. We hypothesized that increased elasticity would amplify GGPS, thereby improving the hydrophobicity and cell adhesion on PEG hydrogel surfaces, despite their inherent hydrophilicity. To test this hypothesis, we engineered dilute oligo-PEG gels via a two-step process, creating polymer networks from tetra-PEG clusters with multiple reaction points. These oligo-PEG gels exhibited significantly higher elasticity, turbidity, and shrinkage upon water immersion compared to dilute PEG gels. Detailed characterization through confocal laser scanning microscopy, rheological measurements, and cell adhesion assays revealed distinct biphasic structures, increased hydrophobicity, and enhanced cell attachability in the dilute oligo-PEG gels. Our findings confirm that elasticity is crucial for effective GGPS, providing a novel method for tailoring hydrogel properties without chemical modification.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

Also, the population structure analysis of LSDVs was carried out. Out of 138 scab samples tested from suspected cattle for LSDV, 106 were found positive. Of these, nine representative scab samples were further genetically characterized. Phylogenetic analysis based on the P32 and EEV gene sequences depicted that the LSDV strains of the present study had nucleotide identity of 100% and 99.10-99.45%, respectively with the LSDV/2019 field strains of India. Multiple sequence alignment of the EEV glycoprotein gene sequences revealed nucleotide polymorphisms at three positions viz., G178A, G253A and A459G in circulating LSDV/2022 field strains. Based on the median joining network analysis of the EEV gene, 12 haplotypes were identified among the LSDV populations. Population structure analysis corresponding to the EEV gene revealed high haplotype (0.8486 ± 0.026) and low nucleotide diversities (0.00636 ± 0.0006) and negative values for neutrality indices, indicating a high number of closely related haplotypes and the studied population may have undergone a recent expansion.

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs. Each DSB could use three potential intact homologous DNA sequences as repair template: one from the sister chromatid and the two others from the homologous chromosomes.", - "journal": "Plant reproduction", - "issn": [ - "2194-7961" - ], - "authors": [ - "Nahid Rafiei", - "Arnaud Ronceret" - ], - "doi": "10.1007/s00497-024-00509-7", - "publishedDate": "2024-08-26T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331138", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331087", - "title": "Effect of bioceramic inclusions on gel-cast aliphatic polymer membranes for bone tissue engineering applications: An in vitro study.", - "content": "Polylactic acid (PLA) has been extensively used in tissue engineering.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results. Thus, we conclude that scattering induced by a high density of electric dipoles at the interface is dominant cause of the low mobility in SiC MOSFETs.", - "doi": "10.1063/5.0086172", - "authors": [ - "Tetsuo Hatakeyama", - "Hirohisa Hirai", - "Mitsuru Simetani", - "Dai Okamoto", - "Mitsuo Okamoto", - "Shinsuke Harada" - ], - "journal": null, - "tags": [ - "physics.app-ph" - ], - "comments": "16pages, 3 figures", - "pdf_url": "http://arxiv.org/pdf/2201.03821v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2201.03821v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 2 - ], - "score": 0.5, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331138", - "title": "The plant early recombinosome: a high security complex to break DNA during meiosis.", - "content": "The formacion of numerous unpredictable DNA Double Strand Breaks (DSBs) on chromosomes iniciates meiotic recombination. In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs.

Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance.

In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

Poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is commonly used as a hole transport layer (HTL) in the inverted PSCs to achieve efficient and stable performance. However, PEDOT:PSS can corrode ITO, affecting device efficiency. Moreover, the hydrophilic nature of PEDOT:PSS compromises device stability. In this work, Poly (3-hexylthiophene-2,5-diyl) (P3HT), known for its good hydrophobicity, was used to modify the surface of PEDOT:PSS, reducing its water absorption and thereby enhancing the efficiency and stability of PSCs. The results reveal that incorporating P3HT effectively enhances the hydrophobicity of PEDOT:PSS. Furthermore, it fosters the development of large-grain perovskite film on the PEDOT:PSS/P3HT bilayer. This enhancement leads to a power conversion efficiency (PCE) of 19.78% for PSCs, with an increase by 16% than that of reference cells (17.04% of PCE). Following a duration of 1000 h, the PCE for the device modified with P3HT remains above 90%, while the PCE of the reference device is below 70%. These findings suggest that using P3HT in conjunction with PEDOT:PSS as a bilayer HTL can concurrently and proficiently improve the efficiency and stability of PSCs.", - "journal": "Nanomaterials (Basel, Switzerland)", - "issn": [ - "2079-4991" - ], - "authors": [ - "Xiude Yang", - "Minghao Luo", - "Qianqian Zhang", - "Haishen Huang", - "Yanqing Yao", - "Yuanlin Yang", - "Ying Li", - "Wan Cheng", - "Ping Li" - ], - "doi": "10.3390/nano14181476", - "publishedDate": "2024-09-06T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330634", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2010.09485v1", - "title": "Determination of the Interface between Amorphous Insulator and Crystalline 4H-SiC in Transmission Electron Microscope Image by using Convolutional Neural Network", - "publishedDate": "2020-10-14T08:28:01", - "content": "A rough interface seems to be one of the possible reasons for low channel mobility (conductivity) in SiC MOSFETs.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results. Thus, we conclude that scattering induced by a high density of electric dipoles at the interface is dominant cause of the low mobility in SiC MOSFETs.", - "doi": "10.1063/5.0086172", - "authors": [ - "Tetsuo Hatakeyama", - "Hirohisa Hirai", - "Mitsuru Simetani", - "Dai Okamoto", - "Mitsuo Okamoto", - "Shinsuke Harada" - ], - "journal": null, - "tags": [ - "physics.app-ph" - ], - "comments": "16pages, 3 figures", - "pdf_url": "http://arxiv.org/pdf/2201.03821v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2201.03821v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331420", - "title": "Estimating the Size of Populations at High Risk of Malaria in 2 Operational Districts in Cambodia: Household-Based Survey.", - "content": "Cambodia is targeting the elimination of malaria by 2025.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals. Thus, the cable and motor surge impedances can be matched over a short time to prevent reflected waves.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance. Since commercial SiC MOSFETs are capable of operating in a wide range of temperatures, it is important to know the values of ITCs in the whole temperature range of operation. Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances. In addition, it is shown that at high frequencies stray inductances of the TO-247-3 package result in a change of the extracted values of the on-state ITCs.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware.

Here, we present time-gated spectroscopic characterization of these interfacial point defects. Unlike in previous studies, the devices were opened in such a way that the drain-contact remained electrically active. A separate examination of the photons emitted at the rising and falling transitions of the gate-source voltage enabled the extraction of two different spectral components.

Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

The hole injection in specific regions of the device explained the failure of the gate oxide under stress. In this way, the key role of the TD in the dielectric breakdown of 4H-SiC MOSFET was unambiguously demonstrated.", - "doi": "10.1088/1361-6528/ab5ff6", - "authors": [ - "P. Fiorenza", - "M.

The present paper reports the green synthesis of CuO NPs and B-doped CuO NPs (B-CuO NPs) from Livistona chinensis leaf extract. Not much work has been reported on the use of the plant extract for the fabrication of NPs, particularly those of Cu and its doped counterparts. Various spectroscopic techniques were used to characterize the synthesized NPs. In the FT-IR spectra, peaks obtained at 504 cm-1 to 600 cm-1 were due to Cu-O vibrations. The energy dispersive X-ray analysis (EDX) spectra confirmed the CuO NPs' composition and B's presence inside the NPs. The peak pattern in X-ray diffraction (XRD) spectrum confirmed the crystalline and monoclinic phases of the NPs. The average crystalline size of CuO NPs and B-CuO NPs was 19.56 nm and 17.30 nm respectively. The CuO and B-CuO NPs were tested against three Gram-positive bacterial strains namely Bacillus subtilis, Micrococcus luteus, and Staphylococcus aureus and three Gram-negative Escherichia coli, Salmonella abony, and Pseudomonas aeruginosa through Agar well diffusion method and it was found that CuO NPs showed higher activity than B-CuO NPs.", - "journal": "Chemistry & biodiversity", - "issn": [ - "1612-1880" - ], - "authors": [ - "Ekhlakh Veg", - "Azam Raza", - "Smita Rai", - "Swati Sharma", - "Anushka Pandey", - "Mohammad Imran Ahmad", - "Sabeeha Jabeena", - "Seema Joshi", - "Tahmeena Khan" - ], - "doi": "10.1002/cbdv.202401596", - "publishedDate": "2024-09-27T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39330976", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2310.06184v2", - "title": "A Brief Review of Single Event Burnout Failure Mechanisms and Design Tolerances of Silicon Carbide MOSFETs", - "publishedDate": "2023-10-09T22:24:06", - "content": "Radiation hardening of the MOSFET is of the highest priority for sustaining high-power systems in the space radiation environment.

We hypothesized that increased elasticity would amplify GGPS, thereby improving the hydrophobicity and cell adhesion on PEG hydrogel surfaces, despite their inherent hydrophilicity. To test this hypothesis, we engineered dilute oligo-PEG gels via a two-step process, creating polymer networks from tetra-PEG clusters with multiple reaction points. These oligo-PEG gels exhibited significantly higher elasticity, turbidity, and shrinkage upon water immersion compared to dilute PEG gels. Detailed characterization through confocal laser scanning microscopy, rheological measurements, and cell adhesion assays revealed distinct biphasic structures, increased hydrophobicity, and enhanced cell attachability in the dilute oligo-PEG gels.

However, the most critical challenge to the commercialization of Ga$_2$O$_3$ electronics is overheating, which impacts the device's performance and reliability. We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs. This LT approach is essential to preserve the structural integrity of the composite wafer. These LT-grown epitaxial Ga$_2$O$_3$ MOSFETs deliver high thermal performance (56% reduction in channel temperature), high voltage blocking capabilities up to 2.45 kV, and power figures of merit of $\\sim$ 300 MW/cm$^2$, which is a record high for any heterogeneously integrated Ga$_2$O$_3$ devices reported to date. This work is the first realization of multi-kilovolt homoepitaxial Ga$_2$O$_3$ power MOSFETs fabricated on a composite substrate with high heat transfer performance which delivers state-of-the-art power density values while running much cooler than those on native substrates. Thermal characterization and modeling results reveal that a Ga$_2$O$_3$/diamond composite wafer with a reduced Ga$_2$O$_3$ thickness ($\\sim$ 1 $\\mu$m) and thinner bonding interlayer ($<$ 10 nm) can reduce the device thermal impedance to a level lower than today's GaN-on-SiC power switches.", - "doi": null, - "authors": [ - "Yiwen Song", - "Arkka Bhattacharyya", - "Anwarul Karim", - "Daniel Shoemaker", - "Hsien-Lien Huang", - "Saurav Roy", - "Craig McGray", - "Jacob H.

By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals. Thus, the cable and motor surge impedances can be matched over a short time to prevent reflected waves. As a result, the leakage currents passing through the ball bearing and overvoltage stress on the motor insulation can be suppressed significantly.", - "doi": null, - "authors": [ - "Fahmid Sadeque", - "Fariba Fateh", - "JiangBiao He", - "Behrooz Mirafzal" - ], - "journal": null, - "tags": [ - "eess.SY", - "cs.SY" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2212.13211v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2212.13211v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 6 - ], - "score": 0.16666666666666666, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331382", - "title": "Modular Synthesis of Azidobicyclo[2.1.1]hexanes via (3 + 2) Annulation of α-Substituted Vinyl Azides and Bicyclo[1.1.0]butanes.", - "content": "Here, we present a mild and rapid method to access azidobicyclo[2.1.1]hexanes via formal (3 + 2) cycloaddition of α-substituted vinyl azides and bicyclo[1.1.0]butanes under Lewis acid catalysis.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance. Since commercial SiC MOSFETs are capable of operating in a wide range of temperatures, it is important to know the values of ITCs in the whole temperature range of operation. Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

A separate examination of the photons emitted at the rising and falling transitions of the gate-source voltage enabled the extraction of two different spectral components.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance. Since commercial SiC MOSFETs are capable of operating in a wide range of temperatures, it is important to know the values of ITCs in the whole temperature range of operation. Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

Low on-resistance and low input capacitance of GaN HEMTs are suitable for a high-frequency gate driver from the logic level, and robustness of SiC MOSFET with high avalanche capability is suitable for a valve transistor in power converters. Our proposed gate driver consists of digital isolators, complementary Si MOSFETs, and GaN HEMTs. The GaN HEMT push-pull stage has a high driving capability owing to its superior switching characteristics, and complementary Si MOSFETs can enhance the control signal from the digital isolator.

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs. Each DSB could use three potential intact homologous DNA sequences as repair template: one from the sister chromatid and the two others from the homologous chromosomes.", - "journal": "Plant reproduction", - "issn": [ - "2194-7961" - ], - "authors": [ - "Nahid Rafiei", - "Arnaud Ronceret" - ], - "doi": "10.1007/s00497-024-00509-7", - "publishedDate": "2024-08-26T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331138", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2009.04835v1", - "title": "Understanding the role of threading dislocations on 4H-SiC MOSFET breakdown under high temperature reverse bias stress", - "publishedDate": "2020-09-10T13:20:41", - "content": "The origin of dielectric breakdown was studied on 4H-SiC MOSFETs that failed after three months of high temperature reverse bias (HTRB) stress.

We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs. This LT approach is essential to preserve the structural integrity of the composite wafer. These LT-grown epitaxial Ga$_2$O$_3$ MOSFETs deliver high thermal performance (56% reduction in channel temperature), high voltage blocking capabilities up to 2.45 kV, and power figures of merit of $\\sim$ 300 MW/cm$^2$, which is a record high for any heterogeneously integrated Ga$_2$O$_3$ devices reported to date.

We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs. This LT approach is essential to preserve the structural integrity of the composite wafer. These LT-grown epitaxial Ga$_2$O$_3$ MOSFETs deliver high thermal performance (56% reduction in channel temperature), high voltage blocking capabilities up to 2.45 kV, and power figures of merit of $\\sim$ 300 MW/cm$^2$, which is a record high for any heterogeneously integrated Ga$_2$O$_3$ devices reported to date. This work is the first realization of multi-kilovolt homoepitaxial Ga$_2$O$_3$ power MOSFETs fabricated on a composite substrate with high heat transfer performance which delivers state-of-the-art power density values while running much cooler than those on native substrates. Thermal characterization and modeling results reveal that a Ga$_2$O$_3$/diamond composite wafer with a reduced Ga$_2$O$_3$ thickness ($\\sim$ 1 $\\mu$m) and thinner bonding interlayer ($<$ 10 nm) can reduce the device thermal impedance to a level lower than today's GaN-on-SiC power switches.", - "doi": null, - "authors": [ - "Yiwen Song", - "Arkka Bhattacharyya", - "Anwarul Karim", - "Daniel Shoemaker", - "Hsien-Lien Huang", - "Saurav Roy", - "Craig McGray", - "Jacob H.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals. Thus, the cable and motor surge impedances can be matched over a short time to prevent reflected waves.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated.

A separate examination of the photons emitted at the rising and falling transitions of the gate-source voltage enabled the extraction of two different spectral components.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

Also, the population structure analysis of LSDVs was carried out. Out of 138 scab samples tested from suspected cattle for LSDV, 106 were found positive. Of these, nine representative scab samples were further genetically characterized. Phylogenetic analysis based on the P32 and EEV gene sequences depicted that the LSDV strains of the present study had nucleotide identity of 100% and 99.10-99.45%, respectively with the LSDV/2019 field strains of India. Multiple sequence alignment of the EEV glycoprotein gene sequences revealed nucleotide polymorphisms at three positions viz., G178A, G253A and A459G in circulating LSDV/2022 field strains.

It has influenced areas of computer science such as automata theory, functional programming, and semantics. Certain objects naturally exhibit two classes of morphisms, leading to the concept of a double category, which has found applications in computing science (e.g., ornaments, profunctor optics, denotational semantics). The emergence of diverse categorical structures motivated a unified framework for category theory. However, unlike other mathematical objects, classification of categorical structures faces challenges due to various relevant equivalences. This poses significant challenges when pursuing the formalization of categories and restricts the applicability of powerful techniques, such as transport along equivalences. This work contends that univalent foundations offers a suitable framework for classifying different categorical structures based on desired notions of equivalences, and remedy the challenges when formalizing categories. The richer notion of equality in univalent foundations makes the equivalence of a categorical structure an inherent part of its structure. We concretely apply this analysis to double categorical structures. We characterize and formalize various definitions in Coq UniMath, including (pseudo) double categories and double bicategories, up to chosen equivalences. We also establish univalence principles, making chosen equivalences part of the double categorical structure, analyzing strict double setcategories (invariant under isomorphisms), pseudo double setcategories (invariant under isomorphisms), univalent pseudo double categories (invariant under vertical equivalences) and univalent double bicategories (invariant under gregarious equivalences).", - "doi": null, - "authors": [ - "Nima Rasekh", - "Niels van der Weide", - "Benedikt Ahrens", - "Paige Randall North" - ], - "journal": null, - "tags": [ - "math.CT" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2402.05265v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2402.05265v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 7 - ], - "score": 0.14285714285714285, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331177", - "title": "Combining SiO", - "content": "Cadmium (Cd) pollution in water and soil seriously threatens human health.

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs. Each DSB could use three potential intact homologous DNA sequences as repair template: one from the sister chromatid and the two others from the homologous chromosomes.", - "journal": "Plant reproduction", - "issn": [ - "2194-7961" - ], - "authors": [ - "Nahid Rafiei", - "Arnaud Ronceret" - ], - "doi": "10.1007/s00497-024-00509-7", - "publishedDate": "2024-08-26T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331138", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2406.08701v1", - "title": "Impacts of Backside Insulation on the Dynamic On-Resistance of Lateral p-GaN HEMTs-on-Si", - "publishedDate": "2024-06-12T23:58:41", - "content": "We examined the effect of backside insulation on the dynamic on-resistance of lateral p-GaN HEMTs.

Results through Sentaurus TCAD simulation suggest that the use of backside insulation in devices gradually disperses potential to the buffer barrier.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated.

The proton light yield of a series of commercial fast plastic organic scintillators---EJ-200, EJ-204, and EJ-208---was measured via a double time-of-flight technique at the 88-Inch Cyclotron at Lawrence Berkeley National Laboratory.

The higher resolution and mass accuracy of the orbitrap analyzer compared with previously employed Q-TOF instrumentation provided high confidence in bacterial proteoform and species identification by top-down protein analysis.", - "journal": "Analytical chemistry", - "issn": [ - "1520-6882" - ], - "authors": [ - "Bob Challen", - "Lily R Adair", - "Rainer Cramer" - ], - "doi": "10.1021/acs.analchem.4c04458", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331381", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/1711.03659v1", - "title": "Frequency-comb based double-quantum two-dimensional coherent spectroscopy identifies collective hyperfine resonances in atomic vapor induced by dipole-dipole interactions", - "publishedDate": "2017-11-10T01:06:56", - "content": "Frequency comb based multidimensional coherent spectroscopy is a novel optical method that enables high resolution measurement in a short acquisition time.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results. Thus, we conclude that scattering induced by a high density of electric dipoles at the interface is dominant cause of the low mobility in SiC MOSFETs.", - "doi": "10.1063/5.0086172", - "authors": [ - "Tetsuo Hatakeyama", - "Hirohisa Hirai", - "Mitsuru Simetani", - "Dai Okamoto", - "Mitsuo Okamoto", - "Shinsuke Harada" - ], - "journal": null, - "tags": [ - "physics.app-ph" - ], - "comments": "16pages, 3 figures", - "pdf_url": "http://arxiv.org/pdf/2201.03821v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2201.03821v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 5 - ], - "score": 0.2, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331418", - "title": "Hydrophobic ZIF-8 nanoparticles loaded on chitosan for improved methanol adsorption from fermented wine.", - "content": "Metal-organic frameworks (MOFs) have great potential for the adsorption of minor molecular alcohols in the vapor phase.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals. Thus, the cable and motor surge impedances can be matched over a short time to prevent reflected waves. As a result, the leakage currents passing through the ball bearing and overvoltage stress on the motor insulation can be suppressed significantly.", - "doi": null, - "authors": [ - "Fahmid Sadeque", - "Fariba Fateh", - "JiangBiao He", - "Behrooz Mirafzal" - ], - "journal": null, - "tags": [ - "eess.SY", - "cs.SY" - ], - "comments": null, - "pdf_url": "http://arxiv.org/pdf/2212.13211v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2212.13211v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 6 - ], - "score": 0.16666666666666666, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331382", - "title": "Modular Synthesis of Azidobicyclo[2.1.1]hexanes via (3 + 2) Annulation of α-Substituted Vinyl Azides and Bicyclo[1.1.0]butanes.", - "content": "Here, we present a mild and rapid method to access azidobicyclo[2.1.1]hexanes via formal (3 + 2) cycloaddition of α-substituted vinyl azides and bicyclo[1.1.0]butanes under Lewis acid catalysis.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance. Since commercial SiC MOSFETs are capable of operating in a wide range of temperatures, it is important to know the values of ITCs in the whole temperature range of operation. Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances. In addition, it is shown that at high frequencies stray inductances of the TO-247-3 package result in a change of the extracted values of the on-state ITCs.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE. Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices.

Here, we present time-gated spectroscopic characterization of these interfacial point defects. Unlike in previous studies, the devices were opened in such a way that the drain-contact remained electrically active. A separate examination of the photons emitted at the rising and falling transitions of the gate-source voltage enabled the extraction of two different spectral components.

Knowledge of the exact values for the ITCs is required in order to perform accurate and predictive compact model simulations of their dynamic performance.

Direct measurements of the ITCs with standard equipment is possible only at low current levels (i.e. in the off-state (Vgs < Vth) for Vds > 0 V), however their values in the on-state (Vgs>Vth) also influence the MOSFETs switching performance. In this work, ITCs of a planar SiC MOSFET in the on-state are studied by the means of a calibrated TCAD model, revealing substantial temperature dependence in the range of 300-450 K. In the first approximation, this temperature dependence of the ITCs can be explained by a weaker temperature dependence of the MOSFET channel resistance in comparison to its JFET and epitaxial layer resistances.

Low on-resistance and low input capacitance of GaN HEMTs are suitable for a high-frequency gate driver from the logic level, and robustness of SiC MOSFET with high avalanche capability is suitable for a valve transistor in power converters. Our proposed gate driver consists of digital isolators, complementary Si MOSFETs, and GaN HEMTs. The GaN HEMT push-pull stage has a high driving capability owing to its superior switching characteristics, and complementary Si MOSFETs can enhance the control signal from the digital isolator.

In this perspective, we propose a 'multi-key lock' model to secure the risky but necesary breaks as well as a 'one per pair of cromatids' model for the topoisomerase-like early recombinosome. During meiosis, homologous chromosomes recombine at few sites of crossing-overs (COs) to ensure correct segregation. The initiation of meiotic recombination involves the formation of DNA double strand breaks (DSBs) during prophase I. Too many DSBs are dangerous for genome integrity: if these DSBs are not properly repaired, it could potentially lead to chromosomal fragmentation. Too few DSBs are also problematic: if the obligate CO cannot form between bivalents, catastrophic unequal segregation of univalents lead to the formation of sterile aneuploid spores. Research on the regulation of the formation of these necessary but risky DSBs has recently advanced in yeast, mammals and plants. DNA DSBs are created by the enzymatic activity of the early recombinosome, a topoisomerase-like complex containing SPO11. This opinion paper reviews recent insights on the regulation of the SPO11 cofactors necessary for the introduction of temporally and spatially controlled DSBs. We propose that a 'multi-key-lock' model for each subunit of the early recombinosome complex is required to secure the formation of DSBs. We also discuss the hypothetical implications that the established topoisomerase-like nature of the SPO11 core-complex can have in creating DSB in only one of the two replicated chromatids of early prophase I meiotic chromosomes. This hypothetical 'one per pair of chromatids' DSB formation model could optimize the faithful repair of the self-inflicted DSBs. Each DSB could use three potential intact homologous DNA sequences as repair template: one from the sister chromatid and the two others from the homologous chromosomes.", - "journal": "Plant reproduction", - "issn": [ - "2194-7961" - ], - "authors": [ - "Nahid Rafiei", - "Arnaud Ronceret" - ], - "doi": "10.1007/s00497-024-00509-7", - "publishedDate": "2024-08-26T00:00:00", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331138", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 8 - ], - "score": 0.125, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2009.04835v1", - "title": "Understanding the role of threading dislocations on 4H-SiC MOSFET breakdown under high temperature reverse bias stress", - "publishedDate": "2020-09-10T13:20:41", - "content": "The origin of dielectric breakdown was studied on 4H-SiC MOSFETs that failed after three months of high temperature reverse bias (HTRB) stress.

We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs. This LT approach is essential to preserve the structural integrity of the composite wafer. These LT-grown epitaxial Ga$_2$O$_3$ MOSFETs deliver high thermal performance (56% reduction in channel temperature), high voltage blocking capabilities up to 2.45 kV, and power figures of merit of $\\sim$ 300 MW/cm$^2$, which is a record high for any heterogeneously integrated Ga$_2$O$_3$ devices reported to date.

We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs. This LT approach is essential to preserve the structural integrity of the composite wafer. These LT-grown epitaxial Ga$_2$O$_3$ MOSFETs deliver high thermal performance (56% reduction in channel temperature), high voltage blocking capabilities up to 2.45 kV, and power figures of merit of $\\sim$ 300 MW/cm$^2$, which is a record high for any heterogeneously integrated Ga$_2$O$_3$ devices reported to date. This work is the first realization of multi-kilovolt homoepitaxial Ga$_2$O$_3$ power MOSFETs fabricated on a composite substrate with high heat transfer performance which delivers state-of-the-art power density values while running much cooler than those on native substrates.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals.

Respect to technology advancements in material sciences, power MOSFETs with wide band gap materials have been proposed such as silicon carbide (SiC) and gallium nitride (GaN) as an alternative to existing silicon (Si) based MOSFETs and IGBTs. However, reliability analysis should be performed before substituting SiC-MOSFETs in the place of existing Si-MOSFETs and IGBTs. Due to costly equipment of experimental test setup for accelerated life test, a good reliable and precise simulation-based test bench should be used to test the life test procedure before implementing actual hardware. Therefore, this paper introduces a power cycle (PC) test bench for accelerated life testing for reliability assessment of SiC-MOSFET in harsh offshore environment. The introduced test bench is a simulation-based of power switch in SimScape and LTspice and has been validated with datasheet of 1.2 kV SiC-MOSFET, CAS300M12BM2 by CREE.

The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated.

We fabricated a Ga$_2$O$_3$/4H-SiC composite wafer using a fusion-bonding method. A low temperature ($\\le$ 600 $^{\\circ}$C) epitaxy and device processing approach based on low-temperature (LT) metalorganic vapor phase epitaxy is developed to grow a Ga$_2$O$_3$ epitaxial channel layer on the composite wafer and subsequently fabricate into Ga$_2$O$_3$ power MOSFETs.

We first establish that neither phonon scattering nor Coulomb scattering can be the cause of the low observed mobility in SiC MOSFETs; we establish this fact by comparing the theoretically calculated mobility considering these effects with experimental observations. By considering the threshold voltages and the effective field dependence of the mobility in SiC MOSFETs, it is concluded that the scattering centers of the dominant mechanism are electrically neutral and exhibit a short-range scattering potential. By considering charge distribution around a neutral defect at the interface, it is established that an electric dipole induced by the defect can act as a short-range scattering potential. We then calculate the mobility in SiC MOSFETs assuming that there exist a high density of dipoles at the interface. The calculated dipole-scattering-limited mobility shows a similar dependence on the effective field dependence to that observed in experimental results.

The existing solution to suppress (or eliminate) the reflected wave impact on the motor insulation run by a Si-IGBT or SiC-MOSFET-based drive is to use either a sinewave filter or dv/dt filter. The alternative solution suggested in this article is to implement a high-bandwidth electronic circuit at the end of the cable or at the motor terminals to match the surge impedance of the cable and motor. The high-frequency voltage ringing due to the reflected waves in motor drives is around 1 MHz, depending on the cable parameters and the length of the cable. In the proposed method, the electronic circuit can quickly detect the dv/dt rise and fall edges and adjust the electronic circuit equivalent impedance when pulses arrive the motor terminals.

Preliminary hardware circuits are also shown for further experimental tests. The captured data from the Device-Under-Test (DUT) in different ambient temperatures are envisioned and provide critical information about the failure mechanisms and lifetime characteristics of power devices. The provided lifetime characteristics data of SiC-MOSFET can be used to statistically estimate the Remaining-Useful-Lifetime (RUL) of component in a real application such as downhole motor drives.", - "doi": null, - "authors": [ - "Shiva Geraei", - "Saeed Hasanpour Aghdam" - ], - "journal": null, - "tags": [ - "eess.SY", - "cs.SY" - ], - "comments": "9 pages, 9 figures", - "pdf_url": "http://arxiv.org/pdf/2001.05580v1", - "engine": "arxiv", - "parsed_url": [ - "http", - "arxiv.org", - "/abs/2001.05580v1", - "", - "", - "" - ], - "engines": [ - "arxiv" - ], - "positions": [ - 9 - ], - "score": 0.1111111111111111, - "category": "science" - }, - { - "template": "paper.html", - "url": "https://www.ncbi.nlm.nih.gov/pubmed/39331379", - "title": "A Method for Treating Significant Conformational Changes in Alchemical Free Energy Simulations of Protein-Ligand Binding.", - "content": "Relative binding free energy (RBFE) simulation is a rigorous approach to the calculation of quantitatively accurate binding free energy values for protein-ligand binding in which a reference binder is gradually converted to a target binder through alchemical transformation during the simulation. The success of such simulations relies on being able to accurately sample the correct conformational phase space for each alchemical state; however, this becomes a challenge when a significant conformation change occurs between the reference and target binder-receptor complexes. Increasing the simulation time and using enhanced sampling methods can be helpful, but effects can be limited, especially when the free energy barrier between conformations is high or when the correct target complex conformation is difficult to find and maintain. Current RBFE protocols seed the reference complex structure into every alchemical window of the simulation. In our study, we describe an improved protocol in which the reference structure is seeded into the first half of the alchemical windows, and the target structure is seeded into the second half of the alchemical windows. By applying information about the relevant correct end point conformations to different simulation windows from the beginning, the need for large barrier crossings or simulation prediction of the correct structures during an alchemical simulation is in many cases obviated. In the diverse cases we examine below, the simulations yielded free energy predictions that are satisfactory as compared to experiment and superior to running the simulations utilizing the conventional protocol. The method is straightforward to implement for publicly available FEP workflows.", - "journal": "Journal of chemical theory and computation", - "issn": [ - "1549-9626" - ], - "authors": [ - "Junzhuo Liao", - "Alina P Sergeeva", - "Edward D Harder", - "Lingle Wang", - "Jared M Sampson", - "Barry Honig", - "Richard A Friesner" - ], - "doi": "10.1021/acs.jctc.4c00954", - "engine": "pubmed", - "parsed_url": [ - "https", - "www.ncbi.nlm.nih.gov", - "/pubmed/39331379", - "", - "", - "" - ], - "engines": [ - "pubmed" - ], - "positions": [ - 10 - ], - "score": 0.1, - "category": "science" - }, - { - "template": "paper.html", - "url": "http://arxiv.org/abs/2404.13463v1", - "title": "Time-Gated Optical Spectroscopy of Field-Effect Stimulated Recombination via Interfacial Point Defects in Fully-Processed Silicon Carbide Power MOSFETs", - "publishedDate": "2024-04-20T20:42:53", - "content": "Fully-processed SiC power metal-oxide-semiconductor field-effect transistors (MOSFETs) emit light during switching of the gate terminal, while both drain and source terminals are grounded. The emitted photons are caused by defect-assisted recombination of electrons and holes at the 4H-SiC/SiO$_2$ interface and can be detected through the SiC substrate. Here, we present time-gated spectroscopic characterization of these interfacial point defects. Unlike in previous studies, the devices were opened in such a way that the drain-contact remained electrically active. A separate examination of the photons emitted at the rising and falling transitions of the gate-source voltage enabled the extraction of two different spectral components. One of these components consists of a single transition with phonon replicas of a local vibrational mode (LVM) with an astonishingly high energy of 220 meV $\\unicode{x2013}$ well above the highest phonon modes in 4H-SiC and SiO$_2$ of 120 meV and 137 meV, respectively. Based on a quantum mechanical model, we successfully fitted its emission spectrum and assigned it to donor-acceptor pair recombination involving a carbon cluster-like defect. Other transitions were assigned to EH$_{6/7}$-assisted, EK$_2$-D, and nitrogen-aluminum donor-acceptor pair recombination. Due to the relevance of these defects in the operation of SiC MOSFETs, these novel insights will contribute to improved reliability and performance of these devices.", - "doi": "10.1103/PhysRevApplied.22.024075", - "authors": [ - "Maximilian W.
