Energy harvesting is the conversion of unused or wasted energy in ambient environment into useful electrical [...]

Sufficient conditions for the long run non-superneutrality of money are established in a neoclassical growth model with a labor-leisure choice. Money is held to satisfy a cash-in-advance constraint on consumption purchases. Production requires capital and labor while period utility depends on consumption and leisure. Sufficient conditions for increased money growth to reduce output in the long ...

Axonal growth depends on axonal transport. We report the first global analysis of mitochondrial transport during axonal growth and pauses. In the proximal axon, we found that docked mitochondria attached to the cytoskeletal framework that were stationary relative to the substrate and fast axonal transport fully accounted for mitochondrial transport. In the distal axon, we found both fast mitoch...

Understanding the fatigue crack growth phenomenon in railheads requires a study of driving forces such as the crack tip opening and sliding displacements, under repeated rolling contact. Finite element simulations, allowing elastic-plastic deformation, and mixed-mode crack growth laws were utilized to demonstrate that the fatigue crack growth rates display a minimum after a finite amount of cra...
