Abstract: In this paper, we employ an unmanned aerial vehicle (UAV) to ensurethe freshness of sensing data, as measured by the age of information (AoI), in Internet of Things (IoT) networks.

Abstract: This study developed a gradient-based algorithm to synthesize arbitrary power patterns with only element phases. This algorithm does not rely on any general-purpose nonlinear solver and ...

Every ecosystem runs on balance between stealth and detection. This video explores how animals evolved camouflage using light-bending nanostructures, pigment cells, and body pattern algorithms — and ...
