Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

Advanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Reducing Personalization Time and Energy Cost While Walking Outdoors with a Portable Exosuit

Advanced Robotics Research, EarlyView.
Rapid Real‐World Optimization! An AF‐based human‐in‐the‐loop optimization strategy rapidly personalizes a portable hip extension exosuit for incline walking. Real‐time Bayesian optimization of assistive force significantly reduces metabolic energy—up to 16.2%—while converging in just 3 min 24 s.

Communication Efficient Federated Learning With Quantization-Aware Training Design

IEEE Transactions on Machine Learning in Communications and Networking
Model quantization is an effective method that can improve communication efficiency in federated learning (FL). The existing FL quantization protocols almost stay at the level of post-training quantization (PTQ), which comes at the cost of large ...
