Propagation of Long Electrical Waves

Propagation of tectonic waves

Propagation of sinusoidal electrical waves along the spinal cord during a fictive motor task.

We present for the first time direct electrophysiological evidence of the phenomenon of traveling electrical waves produced by populations of interneurons within the spinal cord. We show that, during a fictive rhythmic motor task, scratching, an electrical field potential of spinal interneurons takes the shape of a sinuous wave, "sweeping" the lumbosacral spinal cord rostrocaudally with a mean ...

Neutrino Propagation Through Helioseismic Waves

Motivated by earlier calculations showing large effects when neutrinos propagate through fluctuating media, we perform here a detailed analysis of how density fluctuations in the sun in the form of helioseismic waves can modify the MSW solution to the solar neutrino problem. We find negligible effects for the MSW spectrum, even under extreme circumstances. There are two main reasons why our con...

Effect of Initial Stress on Propagation of Love Waves in an Anisotropic Porous Layer

In the present paper, effect of initial stresses on the propagation of Love waves has been investigated in a fluid saturated, anisotropic, porous layer lying in welded contact over a prestressed, non-homogeneous elastic half space. The dispersion equation of phase velocity has been derived. It has been found that the phase velocity of Love waves is considerably influenced by porosity and anisot...

The effect of the earth's rotation on the propagation of ocean waves over long distances

A~tract--The theory of group velocity is generalized to waves on curved surfaces, and applied to calculating the effect of the earth's rotation on the trajectory and wave vector of a wave packet whose waves have lengths much less than the radius of the earth and periods much less than one day. A geometrical description of the perturbed trajectory is given. If /2 is the angular velocity of the e...
