The three-step master equation: class of parametric stationary solutions
(2005)"We examine the three-step master equation from the standpoint of the general solution of the associated discrete Riccati equation. We report by this means stationary master solutions depending on a free constant parameter, ... -
Talbot effect for dispersion in linear optical fibers and a wavelet approach
(2006)"We shortly recall the mathematical and physical aspects of Talbot’s self-imaging effect occurring in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z = p/q, where p ... -
Improvement and analysis of a pseudo random bit generator by means of cellular automata
(2010)"In this paper, we implement a revised pseudo random bit generator based on a rule-90 cellular automaton. For this purpose, we introduce a sequence matrix HN with the aim of calculating the pseudo random sequences of N ... -
Matrix approach of an encryption system based on cellular automata and its numerical implementation
(2012)"The main components of an encryption system based on rule 90 cellular automata, i.e., two indexed families of permutations and a pseudorandom bit generator are implemented in a very xible way through a convenient matrix ... -
Travelling-wave solutions for Korteweg-de Vries-Burgers equations through factorizations
(2006)"Travelling-wave solutions of the standard and compound form of Korteweg-de Vries-Burgers equations are found using factorizations of the correspond-ing reduced ordinary diferential equations. The procedure leads to solutions ... -
A survey of finite algebraic geometrical structures underlying mutually unbiased quantum measurements
(2006)"The basic methods of constructing the sets of mutually unbiased bases in the Hilbert space of an arbitrary finite dimension are reviewed and an emerging link between them is outlined. It is shown that these methods employ ... -
Chaotic dynamics of a nonlinear electronic converter
(2008)"The nonlinear electronic converter used by Rulkov and collaborators [Rulkov et al., 2001], which is the core of their chaotic oscillator, is modeled and simulated numerically by means of an appropriate direct relationship ... -
A simple circuit with dynamic logic architecture of basic logic gates
(2010)"We report experimental results obtained with a circuit possessing dynamic logic architecture based on one of the theoretical schemes proposed by H. Peng and collaborators in 2008. The schematic diagram of the electronic ... -
Multifractal properties of elementary cellular automata in a discrete wavelet approach of MF-DFA
(2009)"In 2005, Nagler and Claussen (Phys. Rev. E 71, 067103 (2005)) investigated the time series of the elementary cellular automata (ECA) for possible (multi)fractal behavior. They eliminated the polynomial background atb ... -
Mutually unbiased phase states, phase uncertainties, and Gauss sums
(2005)"Mutually unbiased bases (MUBs), which are such that the inner product between two vectors in different orthogonal bases is a constant equal to 1/d?, with d the dimension of the finite Hilbert space, are becoming more and ... -
Reply to the comment by Axel Schulze-Halberg
(2013)"Reply to Comment on H.C. Rosu, O. Cornejo-Perez and P. Chen, \Nonsingular parametric oscillators Darboux related to the classical harmonic oscillator by A. Schulze-Halberg" -
Aristotle: the first encyclopedist
(2002)"Aristotle was the first to declare himself in the class of natural philosophers (physiologoi) and he was the first physicist because he spelled out the first definitions of some basic physical concepts. Moreover, he was ... -
Set-reset flip-flop circuit with a simple output logic
(2012)"The equation of the plane (EOP) in analytic geometry is used to build a logic dynamic architecture, i.e., a combination of set-reset flip-flop (SR-FF) and basic logic gates. This is achieved by using two of the variables ... -

PI-controlled bioreactor as a generalized Liénard system
(Elsevier, 2007)"It is shown that periodic orbits can emerge in Cholette’s bioreactor model working under the influence of a PI-controller. We find a diffeomorphic coordinate trans-formation that turns this controlled enzymatic reaction ... -
Nonsingular parametric oscillators Darboux-related to the classical harmonic oscillator
(2012)"Interesting nonsingular parametric oscillators which are Darboux related to the classical harmonic oscillator and have periodic dissipative/gain features are identi?ed through a modi?ed factorization method. The same ... -
Solutions of the perturbed KdV equation for convecting fluids by factorizations
(2010)"In this paper, we obtain some new explicit travelling wave solutions of the perturbed KdV equation through recent factorization techniques that can be performed when the coefficients of the equation fulfill a certain ... -
A simple electronic circuit realization of the tent map
(2009)"We present a very simple electronic implementation of the tent map, one of the best-known discrete dynamical systems. This is achieved by using integrated circuits and passive elements only. The experimental behavior of ... -
Words for nobel prizes
(2003)"We present the statistics of the significant nouns and adjectives of social impact figuring in the nominations of the Nobel prizes in Physics and Chemistry over the period of the awards from 1901 to 2001." -
Online monitoring of Mezcal fermentation based on redox potential measurements
(2009)"We describe an algorithm for the continuous monitoring of the biomass and ethanol concentrations as well as the growth rate in the Mezcal fermentation process. The algorithm performs its task having available only the ...
