Study authors Hunter Schweiger (left) and Ash Robbins. Imagine balancing a ruler vertically in the palm of your hand: you have to constantly pay attention to the angle of the ruler and make many small ...

This is an important study that advances our understanding of the transition from quadrupedal to bipedal gait in a neuromechanical model of the Japanese macaque. The method and results are solid; the ...

Abstract: A pendulum wave energy converter (WEC) is one of the most important forms of wave energy harvesting devices. To obtain better performance under broader wave conditions, this article proposes ...

Active matters have been emerging for the micro/nanorobots and biological applications, and rely on the symmetry-broken structures, compositions, or interfacial activities through a physical or ...
