We investigate how the phylogenetic relationship between the species of each interacting guild in a mutualistic ecosystem influences its network of contacts. We develop a dynamical self organized model that reallocates contacts between mutualists, ac

The increasing capacity of modern computers, driven by Moore’s Law, is accompanied by smaller noise margins and higher error rates. In this paper we propose a memory device, consisting of a ring of two identical overdamped bistable forward-coupled

In this paper we analyze the stochastic-resonant behavior of a chain of forward-coupled bistable overdamped oscillators used as a transmission line with possible applications to neurophysiology, information transmission and storage. We drive the line

In this paper we analyze the properties of a chain of forward-coupled bi-stable over-damped oscillators. It is well known that this system displays stochastic resonance and behaves as a transmission line when an adequate amount of noise is added to e

We investigate the relationship between the nested organization of mutualistic systems and their robustness against the extinction of species. We establish that a nested pattern of contacts is the best possible one as far as robustness is concerned,

We study an opinion formation model by the means of a co-evolving complex network where the vertices represent the individuals, characterised by their evolving opinions, and the edges represent the interactions among them. The network adapts to the s

We analyze a system consisting in many elastically coupled particles that are placed in a periodic ratchet potential on a ring. The system is assumed to be overdamped and driven by an external potential that is periodic both in space and time. The sy
