Study on Instantaneous Stiffness of CylindricalGear In Multitooth Meshes
Jixie chuandong, 1994 通过本文提出的分析轮齿刚度和齿面接触线载荷分布的新方法——台面接触线法向刚阵法，建立了齿面接触线上节点力与法向变形的关系。加入相应的变形协调条件和静力平衡条件，精确简便地作了多对齿同时啮合状态下，轮齿瞬时啮合刚度的分析计算。并用有限元方法编制了专用软件，文中给出了分析计算实例，获得了多齿对同时耦合时的啮合刚度曲线。计算结果具有较高的精度和可靠度。

Advanced Healthcare Materials, EarlyView.ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.

Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents
Advanced Healthcare Materials, EarlyView.Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration
Advanced Healthcare Materials, EarlyView.Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

Advanced Healthcare Materials, EarlyView.ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)

A Methodology for Measuring Actual Mesh Stiffness in Gear Pairs
VibrationThe measurement of the meshing stiffness in gear pairs is a technological problem. Many studies have been conducted, but a few results are available. A tailored test bench was designed and realized to measure the Static Transmission Error in two mating gears to address this issue.
