Effects of two neck rail positions on heifer behavior and stall cleanliness in free stall barn
Agriculture and Natural Resources, 2017 Stall usage and cleanliness are affected by stall design, which includes neck rail positions for dairy heifers. A comparison was for two neck rail positions to determine the preferences for tropical dairy heifers in a free stall barn. Twenty four crossbred Holstein pregnant heifers were divided into two groups, one using the current and the second ...

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Pattern Formation in Non‐Equilibrium Architected Materials
Advanced Materials Technologies, EarlyView.This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Force and Motion Generation of Molecular Motors: A Generic Description [PDF]
, 1999 We review the properties of biological motor proteins which move along linear filaments that are polar and periodic. The physics of the operation of such motors can be described by simple stochastic models which are coupled to a chemical reaction.

Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators
Advanced Materials Technologies, EarlyView.Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.
