Air superiority doesn’t come for free — it has to be seized, often at great cost, from an adversary determined to deny it.

Traditionally difficult to access, the terahertz (THz) region of the electromagnetic spectrum (0.1–10 THz), is higher in frequency than most electronic sources and lower in frequency than most optical ...

A novel measurement cell allows, for the first time, soft and hard X-ray investigations under pressures of up to 20 bar and ...

O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the ...

Abstract: This paper proposes an artificial neural network (ANN)-based synthesis method for nonuniform linear arrays with mutual coupling effects. The proposed method can simultaneously optimize the ...
