Sorting ECGs by lag irreversibility
Nazul Merino Negrete, Cesar Maldonado, Raúl Salgado-García
In this work we introduce the lag irreversibility function as a method to assess time-irreversibility in discrete time series. It quantifies the degree of time-asymmetry for the jo…
Trend patterns statistics for assessing irreversibility in cryptocurrencies: time-asymmetry versus inefficiency
Jessica Morales Herrera, Raúl Salgado-García
In this paper, we present a measure of time irreversibility using trend pattern statistics. We define the irreversibility index as the Kullback-Leibler divergence between the distr…
Time-irreversibility tests for random-length time series: the matching-time approach applied to DNA
R. Salgado-García
In this work we implement the so-called matching time estimators for estimating the entropy rate as well as the entropy production rate for symbolic sequences. These estimators are…
Active particles in reactive disordered media: how does adsorption affects diffusion?
R. Salgado-García
In this work we study analytically and numerically the transport properties of non-interacting active particles moving on a -dimensional disordered media. The disorder in the sp…
On the correspondence between Subshifts of Finite Type and Statistical Mechanics Models
Luis Armando Corona, Raul Salgado-Garcia, Edgardo Ugalde
R. Burton and J. Steif developed a strategy to construct examples of strongly irreducible subshifts of finite type admitting several measures of maximal entropy. This strategy expl…
Estimating entropy rate from censored symbolic time series: a test for time-irreversibility
Raul Salgado-Garcia, Cesar Maldonado
In this work we introduce a method for estimating entropy rate and entropy production rate from finite symbolic time series. From the point of view of statistics, estimating entrop…
Open Markov chains: cumulant dynamics, fluctuations and correlations
R. Salgado-Garcia
In this paper we propose a model for open Markov chains that can be interpreted as a system of non-interacting particles evolving according to the rules of a Markov chain. The numb…
Noise-induced rectification in out-of-equilibrium structures
R. Salgado-Garcia
We consider the motion of overdamped particles on random potentials subjected to a Gaussian white noise and a time-dependent periodic external forcing. The random potential is mode…
Degenerated ground-states in a class of 1D Ising-like models: a characterization by symbolic dynamics
L. A. Corona, R. Salgado-Garcia
In this note we study a class of one-dimensional Ising chain having a highly degenerated set of ground-state configurations. The model consists of spin chain having infinite-range…
Unbiased diffusion of Brownian particles on disordered correlated potentials
Raul Salgado-Garcia, Cesar Maldonado
In this work we study the diffusion of non-interacting overdamped particles, moving on unbiased disordered correlated potentials, subjected to Gaussian white noise. We obtain an ex…
Normal and anomalous diffusion of Brownian particles on disordered potentials
R. Salgado-Garcia
In this work we study the transition from normal to anomalous diffusion of Brownian particles on disordered potentials. The potential model consists of a series of "potential hills…
Normal-to-anomalous diffusion transition in disordered correlated potentials: from the central limit theorem to stable laws
R. Salgado-Garcia, Cesar Maldonado
We study the diffusion of an ensemble of overdamped particles sliding over a tilted random poten- tial (produced by the interaction of a particle with a random polymer) with long-r…
Markov Approximations of Gibbs measures for long-range potentials on 1D lattices
Cesar Maldonado, Raul Salgado-Garcia
We study one-dimensional lattice systems with pair-wise interactions of infinite range. We show projective convergence of Markov measures to the unique equilibrium state. For this…
Symbolic Complexity for Nucleotide Sequences: A Sign of the Genome Structure
R. Salgado-Garcia, E. Ugalde
We introduce a method to estimate the complexity function of symbolic dynamical systems from a finite sequence of symbols. We test such complexity estimator on several symbolic dyn…
Exact scaling in the expansion-modification system
Raúl Salgado-García, Edgardo Ugalde
This work is devoted to the study of the scaling, and the consequent power-law behavior, of the correlation function in a mutation-replication model known as the expansion-modifica…
Resonant Response in Non-equilibrium Steady States
R. Salgado-Garcia
The time-dependent probability density function of a system evolving towards a stationary state exhibits an oscillatory behavior if the eigenvalues of the corresponding evolution o…
