Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
Advanced Science, EarlyView.We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Testing Foundations of Biological Scaling Theory Using Automated Measurements of Vascular Networks
, 2015 Scientists have long sought to understand how vascular networks supply blood and oxygen to cells throughout the body. Recent work focuses on principles that constrain how vessel size changes through branching generations from the aorta to capillaries and

Advanced Science, EarlyView.This manuscript presents the WDMS platform, an AI‐assisted, self‐powered wearable dual‐mode sensor for tele‐neurology. It integrates a contact–separation TENG insole with stretchable polyurethane optical‐fiber strain sensors to synchronously track plantar pressure and lower‐limb muscle deformation.

Advanced Science, EarlyView.This study demonstrates that in high‐alloy systems, nanoclusters with high solute tolerance can effectively suppress compositional segregation. This mitigation leads to a concurrent 18.7% increase in strength and 41.5% improvement in ductility, which is attributed to a shear‐bypass synergistic strengthening mechanism. The findings provide a new pathway

A simple centerline extraction approach for 2D polygons
Information Technology and Control, 2016 This paper describes a new two task approach for extracting the centerline from simple 2D polygons. An algorithm of the first task, which generates a set of points for future centerline, is presented. The idea of the algorithm is to use the polygon hatching by parallel lines and creating paths from its middle points in different polygon rotations.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits
Advanced Science, EarlyView.Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.
