Abstract: In this letter, an advanced method is proposed to shape the frequency-dependent performance of radio frequency (RF) power amplifiers (PAs). The core of the method lies in employing a ...

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

An incredible new map could help explain why anger feels similar to fear, and why being in love makes you feel warmhearted. Researchers have used AI to analyse brain imaging data, revealing how we ...

Abstract: Map-free indoor localization methods can achieve localization purpose without a prior environmental map, thus attracting great interest in recent years. However, existing radio-based methods ...
