The multiplayer dynamics of a football game is analyzed to unveil self-similarities in the time evolution of player and ball positioning. Temporal fluctuations in both the team-turf boundary and the ball location are uncovered to follow the rules of fractional Brownian motion with a Hurst...

We study a population involved in a cyclic game of three strategies – the rock-paper-scissors game – whose agents interact through groups of three individuals (triplets), considering the possibility that two weak agents cooperate and beat a strong one. In a wide range of parameters the...

Divorced individuals face complex situations when they have children with different ex-partners, or even more, when their new partners have children of their own. In such cases, and when kids spend every other weekend with each parent, a practical problem emerges: is it possible to have such a...

The exchange fluctuation theorem for heat exchanged between two systems at different temperatures, when kept in direct contact, has been investigated by Jarzynski and Wójcik [Phys. Rev. Lett. <Emphasis Type="Bold">92, 230602 (2004)]. We extend this result to the case where two Langevin reservoirs at different...</emphasis>

We study how the opinions of a group of individuals determine their spatial distribution and connectivity, through an agent-based model. The interaction between agents is described by a Hamiltonian in which agents are allowed to move freely without an underlying lattice (the average network...

In this paper, we numerically investigate energy dissipation caused by traffic in the Nagel-Schreckenberg (NaSch) model with open boundary conditions (OBC). Boundary results in excess energy dissipation. The effects of the stochastic boundary conditions on energy dissipation are discussed. The...

The use of data compressor techniques has allowed to recognize magnetic transitions and their associated critical temperatures [E.E. Vogel, G. Saravia, V. Cortez, Physica A <Emphasis Type="Bold">391, 1591 (2012)]. In the present paper we introduce some new concepts associated to data recognition and extend the use of...</emphasis>

In the article, the traveling wave solutions to a hydrodynamic model for relaxing media are considered. When fluctuations in the model are absent these solutions satisfy the planar dynamical system, which has been studied by means of the qualitative analysis methods. Now we are interested in the...

We report on the dynamics in a parameter plane of a continuous-time damped system driven by a periodic forcing. The dynamics is characterized by considering the Lyapunov exponents spectrum and conventional bifurcation diagrams, to discriminate periodic, quasiperiodic, and chaotic behaviors for...

Erasure of memory is an essential part of information processing. We consider a photochemical model to suggest a protocol for chemical memory erasure. It has been shown that successful erasure may be achieved by a synergy between a very weak but optimal thermal noise and a minuscule linear bias....
