Predicting cortical bone resorption in the mouse tibia under disuse conditions caused by transient muscle paralysis [PDF]
Load removal from the load-bearing bone, such as during extended space travel or prolonged bed rest, negatively affects bone health and leads to significant bone loss.

Dissipation Losses in Artificial Dielectric Layers
Closed-form expressions to describe artificial dielectric layers with finite conductivity are presented. The propagation of a generic plane wave within the artificial material is described by means of transmission line models, where each layer is represented as an equivalent shunt impedance.
