IF electrons move through a gas in an electric field, their number can increase if they ionize gas molecules by collision—the well-known Townsend avalanche. Recently, it has been shown 1 that in ...

Computer scientists have discovered a new way to multiply large matrices faster by eliminating a previously unknown inefficiency, leading to the largest improvement in matrix multiplication efficiency ...

Researchers at the Los Alamos National Laboratory in the US have developed the first ultrafast photodetector made from quantum dots that is capable of directly observing the extra electrons in a ...
