Soliton propagation along optical fibers
Abstract:
Soliton propagation along optical fibers is discussed on the basis of the modified nonlinear Schrödinger equation, which is known to be completely integrable in terms of the inverse-scattering transformation. Numerical observation of soliton propagation reveals various kinds of dynamical behavior, which cannot be accounted for by treating the nonlinear derivative term of the modified nonlinear Schrödinger equation as a perturbation term for the cubic nonlinear Schrödinger equation.

Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...
