Mathematicians finally understand the behavior of an important class of differential equations that describe everything from ...
A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...
Abstract: To improve the computational efficiency of the time-dependent failure probability (TDFP) to system with dynamic loads, materials degeneration and other time-varying factors, a two-phase ...
Abstract: Nowadays, active rectifiers are increasingly used, particularly in grid-connected applications. The high efficiency and reliability of active rectifiers become crucial for increasing the ...
