A novel phase portrait for neuronal excitability. [PDF]
PLoS ONE, 2012 Fifty years ago, FitzHugh introduced a phase portrait that became famous for a twofold reason: it captured in a physiological way the qualitative behavior of Hodgkin-Huxley model and it revealed the power of simple dynamical models to unfold complex ...

Review Article: "The Lagrangian description of aperiodic flows: a case study of the Kuroshio Current" [PDF]
Nonlinear Processes in Geophysics, 2012 This article reviews several recently developed Lagrangian tools and shows how their combined use succeeds in obtaining a detailed description of purely advective transport events in general aperiodic flows.

Characterization of a Dual Nonlinear Helmholtz Resonator
Micromachines, 2022 Resonant elements can generate small amounts of energy that make them pertinent for feeding miniaturized accelerometers with the energy needed. Suitable oscillator candidates are Helmholtz resonators, which have been, for a long time, analyzed and ...

On Targeted Control over Trajectories of Dynamical Systems Arising in Models of Complex Networks
Mathematics, 2023 The question of targeted control over trajectories of systems of differential equations encountered in the theory of genetic and neural networks is considered. Examples are given of transferring trajectories corresponding to network states from the basin
