Nonlinear dynamics of a fractional-order neuron model for nerve impulse propagation in cell membranes: Chaos, multistability, control, and soliton phenomena

Propulsion and Power Research
This study explores the nonlinear dynamics of a nerve impulse neuron model governed by a partial differential equation (PDE) with beta-fractional derivatives, allowing the inclusion of nonlocal temporal dependence in the model formulation.

Deterministic chaos at the ocean surface: applications and interpretations [PDF]

Nonlinear Processes in Geophysics, 1998
Ocean surface, grazing-angle radar backscatter data from two separate experiments, one of which provided coincident time series of measured surface winds, were found to exhibit signatures of deterministic chaos.
