Mechanisms of bone response to injury [PDF]

Journal of Veterinary Diagnostic Investigation, 2017
Bone, despite its relatively inert appearance, is a tissue that is capable of adapting to its environment. Wolff’s law, first described in the 19th century, describes the ability of bone to change structure depending on the mechanical forces applied to it.

Noise suppression of on-chip mechanical resonators by chaotic coherent feedback

, 2015
We propose a method to decouple the nanomechanical resonator in optomechanical systems from the environmental noise by introducing a chaotic coherent feedback loop. We find that the chaotic controller in the feedback loop can modulate the dynamics of the
