Nature of phase transitions in a probabilistic cellular automaton with two absorbing states
Franco Bagnoli, Nino Boccara, Raul Rechtman
We present a probabilistic cellular automaton with two absorbing states, which can be considered a natural extension of the Domany-Kinzel model. Despite its simplicity, it shows a…

Synchronization of non-chaotic dynamical systems
F. Bagnoli, F. Cecconi
A synchronization mechanism driven by annealed noise is studied for two replicas of a coupled-map lattice which exhibits stable chaos (SC), i.e. irregular behavior despite a negati…

Selection, Mutations and Codon Usage in Bacterial Model
Franco Bagnoli, Pietro Lio'
We present a statistical model of bacterial evolution based on the coupling between codon usage and tRNA abundance. Such a model interprets this aspect of the evolutionary process…
