Optical phased array LiDAR chips towards polarization-resolved 4D sensing

Optical phased array (OPA)-based LiDAR technology provides high-speed, solid-state sensing for autonomous vehicles, robotics, and aerial systems. However, current OPA-based LiDAR platforms lack the ability to accurately recognize and classify materials, limiting their effectivene...

Demand Response-Oriented Regulation and Optimization of Air-Conditioning Systems for Metro Stations with Platform Screen Doors

With urban development, metro systems have become a prioritized form of public transport due to their high efficiency and convenience, accompanied by a sharp rise in energy consumption of air-conditioning systems in metro stations. Meanwhile, as the penetration of renewable power...

Melatonin alleviates cadmium toxicity in Solanum nigrum by enhancing pectin-mediated cell wall sequestration and antioxidant

, whereas melatonin partially restored these traits. Melatonin also decreased Cd concentrations in roots, stems, and leaves and reduced root-to-shoot Cd translocation. Meanwhile, Cd partitioning to the cell-wall fraction increased from 56.7% to 67.5% in roots and from 55.1% to 66...

Dynamic Modeling and Self-Tuning Fuzzy Skyhook Control of a Metro Vehicle with a Flexible Carbody and Semi-Active Suspension

Lightweight metro carbodies may exhibit elastic modes within ride-comfort-relevant frequency bands, limiting semi-active suspension controllers tuned offline for nominal conditions. This study proposes a skyhook-based parameter self-tuning fuzzy control (PSTFC) strategy for later...
