Parametric Excitation of a Nonlinear System [PDF]
Journal of Applied Mechanics, 1965 A study has been made on the parametric excitation of a nonlinear system with hardening springs. In the parametric excitation of linear systems, the only subharmonic predicted is a subharmonic of order 1/2. However, in the parametric excitation of non-linear systems, it is shown that higher order subharmonics can exist, depending both on the amplitude ...

Using novel simplified models of excitation for analytic description of initiation propagation and blockage of excitation waves [PDF]
, 2006 We consider applications of a recently suggested new asymptotic approach to detailed ionic models of cardiac excitation. First, we describe a three-variable approximation for the excitation fronts in a detailed ionic model of human atrial kinetics.

The Excitable System in the Cell Surface [PDF]
Circulation, 1962 A membrane model, composed of phospholipid and cholesterol, is described. The electrical resistance and hydration of this model can be controlled by manipulation of ambient ions and by current in ways strongly reminiscent of the behavior of living cells. The behavior of the model may resemble that of the membrane component of the cell.
