, 2017 基于体积粘性系数ζ的分子运动论和连续介质理论,对二维环形激波聚焦（马赫数Ma=2.0）的体积粘性效应进行数值研究,结果表明：对于热完全气体,体积粘性使得激波汇聚中心点处的压力减小、温度增加、密度减小,聚焦点物理参数的改变量分别可达20%、10%、30%,体积粘性效应对环形激波聚焦的影响是不可忽略的;与转动模态相比,在振动模态下环形激波聚焦的体积粘性效应更为明显,因为激波聚焦点附近的体积粘性应力ζΔ·V与热力学压力p达到同一数量级 ...

Hybrid Flexible–Soft Neural Interface as a Practical Solution for Long‐Term Implants
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Implantable neural interfaces face persistent challenges in long‐term functionality due to chronic immune responses, mechanical mismatch with tissue, and material corrosion in vivo. The commonly used flexible materials, such as polyimide and parylene‐C (poly[monochloro‐p‐xylylene]), have advantages in low water vapor permeability and high ...

Basic income trials and the politics of scale: A research agenda
Policy Studies Journal, Volume 54, Issue 3, August 2026.Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate
