Robotic Cell Micromanipulation Skill Learning via Imitation‐Enhanced Reinforcement Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Humans can learn complex and dexterous manipulation tasks by observing videos, imitating and exploring. Multiple end‐effectors manipulation of free micron‐sized deformable cells is one of the challenging tasks in robotic micromanipulation. We propose an imitation‐enhanced reinforcement learning method inspired by the human learning process ...

Warm waters undermine cryptic female choice

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding the thermal sensitivity of reproductive interactions is crucial given global warming. Previous studies have almost exclusively focused on interactions before mating, even though important interactions between the sexes also occur after mating (e.g.
