Learning Optimal Crowd Evacuation from Scratch Through Self‐Play
Advanced Intelligent Systems, EarlyView.How would a superintelligent crowd behave in emergencies? This study develops an approach using multiagent deep reinforcement learning combined with self‐play to discover optimal evacuation strategies for pressure‐aware agents. The model learns behaviors such as queuing and zipper‐merging that significantly surpass traditional approaches in fatality ...

Animal Models and Experimental Medicine, EarlyView.Mitral regurgitation (MR) causes volume overload and disrupts Ca2+ homeostasis. The volume overload leads to cardiac hypertrophy and fibrosis inferred from histopathological studies. Cardiac hypertrophy was identified by increased myocyte cross‐sectional area, left atrial‐to‐aortic root ratio, and left ventricular internal diameter at end‐diastole ...
