two sets of linear frequency sweeping probe light are generated during the rising and falling edge of the triangular wave, thereby two groups of Rayleigh backscattered (RBS) spectra are obtained, ...

Russia has hit on an "offensive triangle" of tactics that are forcing Ukraine to lose ground. The key to reviving Russian airpower has been a surprisingly low-tech weapon: glide bombs. Glide bombs ...

D-Wave's quantum computer reportedly performed a quantum simulation faster than classical computers, simulating quantum dynamics of spin glasses to describe magnetic materials.

A dual-parallel Mach–Zehnder modulator (DPMZM) is employed to modulate the input signals, with a triangular wave applied to the dc port to facilitate downconversion and AOA determination from ...
