The origin of diffusion: the case of non chaotic systems
Fabio Cecconi, Diego del-Castillo-Negrete, Massimo Falcioni +1
We investigate the origin of diffusion in non-chaotic systems. As an example, we consider 1- map models whose slope is everywhere 1 (therefore the Lyapunov exponent is zero) but…
Crucial stages of protein folding through a solvable model: predicting target sites for enzyme-inhibiting drugs
Cristian Micheletti, Fabio Cecconi, Alessandro Flammini +1
An exactly solvable model based on the topology of a protein native state is applied to identify bottlenecks and key-sites for the folding of HIV-1 Protease. The predicted sites ar…
Noise activated granular dynamics
Fabio Cecconi, A. Puglisi, Umberto Marini Bettolo Marconi +1
We study the behavior of two particles moving in a bistable potential, colliding inelastically with each other and driven by a stochastic heat bath. The system has the tendency to…
Short period attractors and non-ergodic behavior in the deterministic fixed energy sandpile model
Franco Bagnoli, Fabio Cecconi, Alessandro Flammini +1
We study the asymptotic behaviour of the Bak, Tang, Wiesenfeld sandpile automata as a closed system with fixed energy. We explore the full range of energies characterizing the acti…
Diffusion, peer pressure and tailed distributions
Fabio Cecconi, Matteo Marsili, Jayanth R. Banavar +1
We present a general, physically motivated non-linear and non-local advection equation in which the diffusion of interacting random walkers competes with a local drift arising from…
