Gaoya dianqi, 2021 局部放电发生时会伴随着发光现象,光学法是一种重要的局部放电检测方法。作为局部放电光学检测的基础,需要对GIL中局放光学信号的传播特性进行研究。文中对不同结构、不同规格参数的GIL进行仿真建模,通过观察探测面和探测点上的光学参数,研究不同GIL结构、不同放电源位置、不同电压等级GIL对局放光学信号在GIL中传播衰减的影响。结果表明GIL腔体的结构会影响探测面上的光斑分布及相对辐照度数值;局放源的位置对探测面的光斑影响十分明显,但对相对辐照度值影响不大;GIL电压等级越高,探测面上光斑分布对比更加鲜明 ...

A conic manifold perspective of elliptic operators on graphs
, 2007 We give a simple, explicit, sufficient condition for the existence of a sector of minimal growth for second order regular singular differential operators on graphs. We specifically consider operators with a singular potential of Coulomb type and base our

Advanced Intelligent Discovery, EarlyView.This study introduces a tree‐based machine learning approach to accelerate USP8 inhibitor discovery. The best‐performing model identified 100 high‐confidence repurposable compounds, half already approved or in clinical trials, and uncovered novel scaffolds not previously studied. These findings offer a solid foundation for rapid experimental follow‐up,
