Distributed LQR design for identical dynamically coupled systems: Application to load frequency control of multi-area power grid [PDF]

open access: yes, 2019
The paper proposes a distributed LQR method for the solution to regulator problems of networks composed of dynamically dependent agents. It is assumed that these dynamical couplings among agents can be expressed in a state-space form of a certain ...

Effect of Low-magnitude, High-frequency Vibration on Osteocytes in the Regulation of Osteoclasts [PDF]

open access: yes, 2010
Osteocytes are well evidenced to be the major mechanosensor in bone, responsible for sending signals to the effector cells (osteoblasts and osteoclasts) that carry out bone formation and resorption. Consistent with this hypothesis, it has been shown that
