Response of a Parametrically Excited System to a Nonstationary Excitation [PDF]
The response of a single-degree-of-freedom system to a nonstationary excitation is investigated by using the method of multiple scales as well as analog- and digital-computer simulations. The unexcited system has one focus and two saddle points. The system can be used to model rolling of ships in head or follower seas.

The Excitable System in the Cell Surface [PDF]
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.
