Why aphids are not pests in cacao? An approach based on a predator-prey model with aging
Vladimir R. V. Assis, Nazareno G. F. Medeiros, Evandro N. Silva +2
We studied a mean-field predator-prey model with aging to simulate the \mbox{interaction} between aphids (\textit{Toxoptera aurantii}) and syrphid larvae in \mbox{cacao} farms in I…
Influence of the interaction range on the thermostatistics of a classical many-body system
Leonardo J. L. Cirto, Vladimir R. V. Assis, Constantino Tsallis
We numerically study a one-dimensional system of classical localized planar rotators coupled through interactions which decay with distance as (). The approach…
Collective behavior of coupled nonuniform stochastic oscillators
Vladimir R. V. Assis, Mauro Copelli
Theoretical studies of synchronization are usually based on models of coupled phase oscillators which, when isolated, have constant angular frequency. Stochastic discrete versions…
An infinite-period phase transition versus nucleation in a stochastic model of collective oscillations
Vladimir R. V. Assis, Mauro Copelli, Ronald Dickman
A lattice model of three-state stochastic phase-coupled oscillators has been shown by Wood et al (2006 Phys. Rev. Lett. 96 145701) to exhibit a phase transition at a critical value…
Discontinuous nonequilibrium phase transitions in a nonlinearly pulse-coupled excitable lattice model
Vladimir R. V. Assis, Mauro Copelli
We study a modified version of the stochastic susceptible-infected-refractory-susceptible (SIRS) model by employing a nonlinear (exponential) reinforcement in the contagion rate an…
Dynamic range of hypercubic stochastic excitable media
Vladimir R. V. Assis, Mauro Copelli
We study the response properties of d-dimensional hypercubic excitable networks to a stochastic stimulus. Each site, modelled either by a three-state stochastic susceptible-infecte…
