Indian astronomers have performed multi-frequency observations of a repeating fast radio burst designated FRB 20201124A.

Abstract: To address the issue of low efficiency under light load conditions when CLLLC converters employ fixed-frequency pulse width modulation, this paper proposes a fixed-frequency improved pulse ...

Abstract: With increasing penetration of renewable energy generation and power electronic converters, waveform distortion and resonance related to high-frequency harmonics and interharmonics ...

Memories and learning processes are based on changes in the brain's neuronal connections, and as a result, in signal transmission between neurons. For the first time, DZNE researchers have observed an ...
