Multiobjective Environmental Cleanup with Autonomous Surface Vehicle Fleets Using Multitask Multiagent Deep Reinforcement Learning

Advanced Intelligent Systems, EarlyView.
This study presents a multitask strategy for plastic cleanup with autonomous surface vehicles, combining exploration and cleaning phases. A two‐headed Deep Q‐Network shared by all agents is traineded via multiobjective reinforcement learning, producing a Pareto front of trade‐offs.

Tuning Cellular Perception in Pluripotent Stem Cells through Topography, Stiffness, and Patterning

Advanced NanoBiomed Research, EarlyView.
Micro‐ and nanotopographical cues, substrate stiffness, and mechanical patterning synergistically direct pluripotent stem cell fate and function by tuning cellular perception at the biointerface. Pluripotent stem cells (PSCs), comprised of embryonic stem cells and induced PSCs, hold tremendous therapeutic potential.
