Sequential epidemic spread between agglomerates of self-propelled agents in one dimension
Pablo de Castro, Felipe Urbina, Ariel Norambuena +1
Motile organisms can form stable agglomerates such as cities or colonies. In the outbreak of a highly contagious disease, the control of large-scale epidemic spread depends on fact…
Phase diagram in a one-dimensional civil disorder model
Ignacio Ormazábal, Felipe Urbina, Félix A. Borotto +1
Epstein's model for a civil disorder is an agent-based model that simulates a social protest process where the central authority uses the police force to dissuade it. The interacti…
Stable and unstable trajectories in a dipolar chain
Jaime Cisternas, Paula Mellado, Felipe Urbina +3
In classical mechanics, solutions can be classified according to their stability. Each of them is part of the possible trajectories of the system. However, the signatures of unstab…
Phase transitions in a decentralized graph-based approach to human language
Javier Vera, Felipe Urbina, Wenceslao Palma
Zipf's law establishes a scaling behavior for word-frequencies in large text corpora. The appearance of Zipfian properties in human language has been previously explained as an opt…
Phase space classification of an Ising Cellular Automaton: the Q2R model
Marco Montalva-Medel, Sergio Rica, Felipe Urbina
An exact characterization of the different dynamical behavior that exhibit the space phase of a reversible and conservative cellular automaton, the so called Q2R model, is shown in…
A decentralized route to the origins of scaling in human language
Felipe Urbina, Javier Vera
The Zipf's law establishes that if the words of a (large) text are ordered by decreasing frequency, the frequency versus the rank decreases as a power law with exponent close to $-…
Master Equation approach to Reversible and Conservative Discrete Systems
Felipe Urbina, Sergio Rica
A master equation approach is applied to a reversible and conservative cellular automata model (Q2R). The Q2R model is a dynamical variation of the Ising model for ferromagnetism t…
Automata networks model for alignment and least effort on vocabulary formation
Javier Vera, Felipe Urbina, Eric Goles
Can artificial communities of agents develop language with scaling relations close to the Zipf law? As a preliminary answer to this question, we propose an Automata Networks model…
