Coexisting chaotic and multi-periodic dynamics in a model of cardiac alternans
Per Sebastian Skardal, Juan G. Restrepo
The spatiotemporal dynamics of cardiac tissue is an active area of research for biologists, physicists, and mathematicians. Of particular interest is the study of period-doubling b…
Mean field theory of assortative networks of phase oscillators
Juan G. Restrepo, Edward Ott
Employing the Kuramoto model as an illustrative example, we show how the use of the mean field approximation can be applied to large networks of phase oscillators with assortativit…
Spatiotemporal Dynamics of Calcium-Driven Cardiac Alternans
Per Sebastian Skardal, Alain Karma, Juan G. Restrepo
We investigate the dynamics of spatially discordant alternans (SDA) driven by an instability of intracellular calcium cycling using both amplitude equations [P. S. Skardal, A. Karm…
Downlink Analysis for a Heterogeneous Cellular Network
Prasanna Madhusudhanan, Juan G. Restrepo, Youjian +2
In this paper, a comprehensive study of the the downlink performance in a heterogeneous cellular network (or hetnet) is conducted. A general hetnet model is considered consisting o…
Onset of Synchronization in the Disordered Hamiltonian Mean Field Model
Juan G. Restrepo, James D. Meiss
We study the Hamiltonian Mean Field (HMF) model of coupled Hamiltonian rotors with a heterogeneous distribution of moments of inertia and coupling strengths. We show that when the…
