Gravitational Waves in General Relativity [PDF]

open access: yesNature, 1960
THE emission of gravitational waves from a finite isolated axially symmetrical material system in otherwise empty space has been investigated by consideration of the metric : Einstein vacuum field equations have been solved by an expansion in negative powers of r which represents ...

Four-quadrant force control with minimal ripple for linear switched reluctance machines

open access: yesCES Transactions on Electrical Machines and Systems, 2020
Linear switch reluctance machine (LSRM) has been tried to act as an alternative generator for direct drive linear wave energy converter (WEC). Many researchers have proposed new topologies of LSRM to improve the power density, efficiency and reliability.

Generating Waves in Corticothalamocortical Networks [PDF]

open access: yesNeuron, 2013
In this issue of Neuron, Stroh et al. (2013) investigate mechanisms of population calcium wave initiation and propagation across cortex and thalamus. They use a novel fiber optic-based method to simultaneously image and excite specific populations of neurons in multiple regions.
