Future electromagnetic systems require compact devices that can control waves in both frequency and propagation direction. Towards this goal, scientists developed a fully passive sliding metasurface that sharply filters unwanted frequencies while steering beams over a wide angular range. This technique opens a new route to coordinated spectral–spatial wave control, enabling potential applications in interference suppression, multiplexing, sensing, and next-generation wireless communication.

Researchers from Hefei University of Technology and the University of Science and Technology of China have proposed a neural architecture search framework that allows an algorithm to automatically look for suitable network structures for EEG-based seizure prediction.

Researchers from Shenzhen Polytechnic University, the University of California, Riverside, and Tsinghua University evaluated real-world emissions from China V and China VI heavy-duty diesel trucks using portable emissions measurement systems (PEMS). The study found that compliant China VI trucks can substantially reduce NO_x and particle number (PN) emissions, but some vehicles still showed severe emission exceedances under real driving conditions, highlighting the importance of in-use monitoring and after-treatment system performance.

Researchers from McGill University, The Hong Kong University of Science and Technology (Guangzhou), and the University of Luxembourg have developed MILD, an AI-powered mediator system that helps drivers and automated vehicles better understand each other. By combining driver-state monitoring, traffic-scene understanding, and explainable decision-making, the system aims to improve trust, safety, and collaboration in partially automated driving.

To address the dual challenges of reducing fuel consumption and ensuring maritime safety under extreme weather, researchers from Dalian University of Technology, Nanyang Technological University, and Chongqing Jiaotong University have developed a novel ship weather routing framework based on Dual-Mode Deep Reinforcement Learning. Utilizing the D3QN algorithm, this framework effectively navigates both normal sea states and severe typhoon conditions, providing a robust route toward maritime safety security and decarbonization.

Researchers developed Found-RL, an open-source platform that integrates vision-language models into reinforcement learning for autonomous driving. By using an asynchronous batch inference framework, Found-RL allows large foundation models to provide semantic feedback without slowing down high-frequency simulation training. Experiments in CARLA show that lightweight reinforcement learning agents can achieve competitive driving performance while maintaining real-time policy inference.
