Summary: Titanium powders were cold sprayed onto polyetheretherketone (PEEK) to investigate the effects of interface microstructure on bonding. The study found that the formation of a transition layer between the metal and polymer deposition can promote adhesion. Microstructural features, such as interfacial area ratio and thermal residual stress, were found to be correlated with adhesive strength values. Understanding these mesoscale features can inform the parameter selection for cold spraying metals onto thermoplastics with strong adhesion.

Summary: This study aimed to investigate the specific role of miR-16 in granulosa cell function in PCOS. The results showed that overexpression of miR-16 or knockdown of Apelin13 could suppress granulosa cell proliferation and enhance apoptosis. Additionally, Apelin13 was identified as a potential target of miR-16. Overexpression of Apelin13 could partially reverse the effects of miR-16 overexpression on granulosa cell proliferation and apoptosis. Moreover, inhibiting Apelin13 could suppress granulosa cell proliferation and block the PI3K/Akt pathway.

Summary: Existing works on impedance control of aerial vehicles are based on known translational velocity, which can be unreliable. To address this issue, a concurrent velocity observation and impedance control framework is proposed. The framework uses cost-optimized monocular vision and IMU measurements instead of GNSS modules, optical flow, and force sensors. Experimental results demonstrate the effectiveness and robustness of the proposed method in unknown environments and under vision system uncertainties.

Summary: This paper focuses on the tracking control of a class of switched nonlinear systems with prescribed performance. A barrier function and a normalized function are introduced to achieve prescribed performance control, ensuring that the tracking error stays within prescribed boundaries. Additionally, a multi-dimensional Taylor network is used to estimate the nonlinearity arising from the backstepping control process. The proposed multi-switching-based adaptive controller guarantees globally uniformly ultimately bounded signals and asymptotic tracking, while achieving global stability and independence from the initial state. The effectiveness of the proposed control method is verified through two simulations.

Summary: To address the issues with CNN-PCA in accurately describing and generalizing complex reservoir geological features, a 3D attention U-Net network was proposed in this study. This network does not rely on a pre-trained C3D video motion analysis model, but instead focuses on complementing the details lost in the dimension reduction process of PCA. The experimental results on a complex river channel sandstone reservoir demonstrate that the 3D attention U-Net network outperforms the CNN-PCA method in capturing the missing details and reflecting fluid flow features, leading to improved history matching results.

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.
