  • Polymer transport in random potentials and the genetic code: The waltz of life
    Cocho, G; Larralde, H; Martínez-Mekler, G; Aldana-González, M (2003)
    We address the question of why the translation from nucleic acids to protein forming amino acids is carried out by triplets known as codons. We approach this problem from a dynamical point of view by considering the ...
  • A relativistically covariant random walk
    Almaguer, J; Larralde, H (2007)
    In this work we present and analyze an extremely simple relativistically covariant random walk model. In our approach, the probability density and the. flow of probability arise naturally as the components of a four-vector ...
  • Scale-free foraging by primates emerges from their interaction with a complex environment
    Boyer, D; Ramos-Fernandez, G; Miramontes, O; Mateos, JL; Cocho, G; Larralde, H; Ramos, H; Rojas, F (2006)
    Scale-free foraging patterns are widespread among animals. These may be the outcome of an optimal searching strategy to find scarce, randomly distributed resources, but a less explored alternative is that this behaviour ...
  • Simple model of a random walk with arbitrarily long memory
    Berrones, A; Larralde, H (2001)
    We present a generalization of the persistent random-walk model in which the step at time n depends on the stare of the step at time n-T, for arbitrary T. This gives rise to arbitrarily long memory effects, yet by an ...
  • The statistics of diffusive flux
    Antonio, AMR; Larralde, H (2005)
    We calculate the explicit probability distribution function for the flux between sites in a simple discrete time diffusive system composed of independent random walkers. We highlight some of the features of the distribution ...
  • Systems with negative specific heat in thermal contact: Violation of the zeroth law
    Larralde, H; Leyvraz, F; Ramirez-Hernández, A (2008)
    Using both numerical simulations and exact expressions for the free energy and microcanonical entropy for a modified Hamiltonian mean-field (HMF) model, we show that when two similar systems with the same intensive parameters ...
  • Violation of the zeroth law of thermodynamics in systems with negative specific heat
    Larralde, H; Leyvraz, F; Ramirez-Hernández, A (2008)
    We show that systems with negative specific heat can violate the zeroth law of thermodynamics. By both numerical simulations and by using exact expressions for free energy and microcanonical entropy, it is shown that if ...
