Abstract: In this work, we consider a two-phase covert communication system assisted by a wireless powered jammer via a reconfigurable intelligent surface (RIS) with discrete phase shifts.

For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient ...

Abstract: Gait phase (GP) estimation is a critical component in control of exoskeletons and prostheses, enabling seamless user interaction in various controllers. In recent years, methods based on ...

Reasoning large language models (LLMs) are designed to solve complex problems by breaking them down into a series of smaller ...
