Abstract Several dynamical systems in nature can be maintained out-of-equilibrium, either through mutual interaction of particles or by external fields. The particle’s transport and the transient dynamics are landmarking of such systems. While sing

Approximately 75% of the worldwide production of hard natural fibers originates from sisal, an industrial crop from arid and semiarid tropical regions. Brazil is the world's largest producer of sisal fiber, accounting for more than 40% of the worldwi

The nonlinear dynamics of a FitzHugh–Nagumo (FHN) neuron driven by an oscillating current and perturbed by a Gaussian noise signal with different intensities [Formula: see text] is investigated. In the noiseless case, stable periodic structures [Ar

Highlights • Modeling the epidemic trends for COVID-19 is essential to take effective containment measures. • We show that time is one of the most important weapons we have in the battle against the COVID-19. • To keep the social distance and t

The purpose of the present work is to apply a recently proposed methodology to enlarge parameter domains for which optimal ratchet currents (RCs) are obtained. This task is performed by adding a suitable periodic perturbation $F_j$ on a Ratchet mappi

In this work we show that optimal ratchet currents of two interacting particles are obtained when stable periodic motion is present. By increasing the coupling strength between identical ratchet maps, it is possible to find, for some parametric combi
