Phase synchronization of coupled bursting neurons and the generalized Kuramoto model
Fabiano A. S. Ferrari, Ricardo L. Viana, Sérgio R. Lopes +1
Bursting neurons fire rapid sequences of action potential spikes followed by a quiescent period. The basic dynamical mechanism of bursting is the slow currents that modulate a fast…
A mechanism for stickness, dealing with extreme events
Taline Suellen Kruger, Paulo Paneque Galuzio, Thiago de Lima Prado +3
In this letter we study how hyperbolic and non hyperbolic regions in the neighborhood of a resonant island perform a important role allowing or forbidding stickiness phenomenon aro…
Super persistent transient in a master-slave configuration with Colpitts oscillators
R. C. Bonetti, S. L. T. de Souza, A. M. Batista +5
Master-slave systems have been intensively investigated to model the application of chaos to communications. We considered Colpitts oscillators coupled according to a master-slave…
Effective transport barriers in nontwist systems
J. D. Szezech, I. L. Caldas, S. R. Lopes +2
In fluids and plasmas with zonal flow reversed shear, a peculiar kind of transport barrier appears in the shearless region, one that is associated with a proper route of transition…
Anomalous transport induced by nonhyperbolicity
Sergio R. Lopes, José D. Szezech, Rodrigo F. Pereira +2
In this letter we study how deterministic features presented by a system can be used to perform direct transport in a {\it quasi}-symmetric potential and weak dissipative system. W…
Bursting synchronization in networks with long-range coupling mediated by a diffusing chemical substance
R. L. Viana, A. M. Batista, C. A. S. Batista +3
Many networks of physical and biological interest are characterized by a long-range coupling mediated by a chemical which diffuses through a medium in which oscillators are embedde…
