Summary: Estimating a nonlinear model from experimental measurements of a vibrating structure remains a challenge, as the dynamical behavior of a nonlinear structure strongly depends on the magnitude of the displacement response. This paper investigates the extrapolation capabilities of data-driven nonlinear state-space models using a subspace approach. The results show that model prediction errors generally increase when extrapolating towards higher excitation levels.

Summary: In this study, a data-centric deep learning approach using neural networks is proposed to predict the thermodynamics of ternary solid solutions. By training neural networks with a dataset of Gibbs free energies computed from a CALPHAD database, ternary systems can be predicted based on their composition and temperature. The study demonstrates the feasibility of predicting the energetics of the FCC solid solution phase in 226 binaries consisting of 23 elements at 11 different temperatures. The sensitivity of data sampling on the prediction accuracy of neural networks over selected ternary systems is examined. It is expected that the prediction accuracy and applicability of the current deep learning workflow can be further improved by integrating advanced descriptors beyond the elemental composition and more curated training datasets.

Summary: When using the Fourier transform method to demodulate the phase from an interferogram, the Gibbs effect often occurs at the edge of the phase picture. Fringe extrapolation is a straightforward method to suppress the Gibbs effect. The traditional exemplar-based algorithm, based on the Criminisi algorithm, is time-consuming. In this study, a structure-guided image-completion method was applied to interferogram extrapolation, which reduces computer memory requirements and saves computing time, achieving a significantly increased speed compared to extrapolation using the Criminisi algorithm.

Summary: This study developed a framework in the R language using interpolation and extrapolation methods for rapid assessment of risk changes and Expected Annual Damages (EAD). It was applied in the city of Perth in Scotland and showed that the methods provided a good approximation of changes in flood depth and EAD for residential properties, with lower confidence for non-residential properties. In the Scottish context, the methods are considered robust for regional and national scale application and enable policy makers to quickly determine the consequences of changes in design rainfall estimates.

Summary: Methamphetamine (Meth) is a highly addictive CNS stimulant, and effective treatment for Meth addiction is currently lacking. This study investigates the role of cell adhesion molecules (CAMs) in Meth addiction and specifically focuses on Contactin 1 (CNTN1). The findings suggest that CNTN1 expression in the nucleus accumbens (NAc) plays a crucial role in Meth-induced addiction, and the mechanism may involve the expression of synapse-associated proteins in the NAc. Silencing CNTN1 expression in the NAc can reverse Meth-induced conditioned place preference (CPP) and decrease the expression levels of NR2A, NR2B, and PSD95 in the NAc.

Summary: The deformation behaviors of a dual-phase Mg alloy containing α-Mg and 18R-LPSO phases were investigated in this study. The 18R phase, accounting for 11.3 vol.%, contributed to 23.0% of the overall alloy deformation. The coordinated twinning deformation of α-Mg matrix through the slip of basal dislocations and the kinking deformation of Mg slices induced by the 18R phase were observed during the early stage of deformation. At the end of deformation, a large number of T2-type stacking faults were generated, improving the ductility of the alloy. This work provides a novel strategy for designing high-strength and good ductility dual-phase Mg alloys.

Summary: The effect of elastic tensile stress on the phase composition and structure of the rust layer formed on Q235 carbon steel in 5% NaCl salt spray was investigated. The results showed that the elastic tensile stress accelerated anodic dissolution, promoting the formation of -FeOOH. Different stress levels resulted in changes in the mass fractions of gamma-FeOOH, alpha-FeOOH, and Fe3O4/gamma-Fe2O3 in the rust layer. Additionally, the stress increased the thickness and decreased the compactness of the rust layer, enhancing its protective capability.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
