Dynamics of a small neutrally buoyant sphere in a fluid and targeting in Hamiltonian systems
Armando Babiano, Julyan H. E. Cartwright, Oreste Piro +1
We show that, even in the most favorable case, the motion of a small spherical tracer suspended in a fluid of the same density may differ from the corresponding motion of an ideal…
Emergent global oscillations in heterogeneous excitable media: The example of pancreatic beta cells
Julyan H. E. Cartwright
Using the standard van der Pol-FitzHugh-Nagumo excitable medium model I demonstrate a novel generic mechanism, diversity, that provokes the emergence of global oscillations from in…
Nonlinear stiffness, Lyapunov exponents, and attractor dimension
Julyan H. E. Cartwright
I propose that stiffness may be defined and quantified for nonlinear systems using Lyapunov exponents, and demonstrate the relationship that exists between stiffness and the fracta…
Three-frequency resonances in dynamical systems
O. Calvo, J. H. E. Cartwright, D. L. Gonzalez +2
We investigate numerically and experimentally dynamical systems having three interacting frequencies: a discrete mapping (a circle map), an exactly solvable model (a system of coup…
