A research team proposes a three-dimensional quantum anomalous Hall effect (3D QAHE) in Weyl semimetals (WSMs) by introducing Rashba spin-orbit coupling. This new state supports chiral surface and hinge states along different spatial directions, with Hall resistance switching between 0, h/e², and ±h/e², offering potential for energy-efficient devices and in-memory computing.
A new PLOS ONE study from Lehigh University introduces a computational model that predicts how electrical stimulation affects atrial fibrillation. The framework could help optimize therapy strategies and move clinicians closer to personalized cardiac care.
Scientists at TU Delft, The Netherlands, have developed a new algorithm that allows multiple autonomous drones to work together to control and transport heavy payloads, even in windy conditions. Ideal for reaching and maintaining hard-to-reach infrastructure, like offshore wind turbines. With often harsh weather, limited payload capacity and unpredictable contact with the environment, it is difficult for current drones to operate safely and effectively. The results have been published in Science Robotics.
