When it comes to annual holidays, there's so much to love about New Year's Eve. All the glitter and sparkles? Great! Strong champagne cocktails? Even better. The possibility of a midnight makeout sesh ...

Abstract: In the conventional implementations of phase-shifted carrier pulsewidth modulation (PSC–PWM) for modular multilevel converters (MMCs), different phases normally adopt identical carrier ...

On December 26, 2025, researchers reported the discovery of wobbling jet structures within the comet's sun-facing anti-tail. Unlike typical comet tails that stream away from the Sun, the anti-tail of ...
