d-Dimensional KPZ equation as a stochastic gradient flow in an evolving landscape : interpretation and time evolution of its generating functional
(2017)The deterministic KPZ equation has been recently formulated as a gradient flow. Its non-equilibrium analog of a free energy—the “non-equilibrium potential” Φ[h], providing at each time the landscape where the stochastic ... -
Distinguishability notion based on Wootters statistical distance : application to discrete maps
(2017)We study the distinguishability notion given by Wootters for states represented by probability density functions. This presents the particularity that it can also be used for defining a statistical distance in chaotic ... -
Effects of rainfall on Culex mosquito population dynamics
(2017)The dynamics of a mosquito population depends heavily on climatic variables such as temperature and precipitation. Since climate change models predict that global warming will impact on the frequency and intensity of ... -
Escaping the trap of ’blocking’ : a kinetic model linking economic development and political competition
(2017)In this paper we present a kinetic model with stochastic game-type interactions, analyzing the relationship between the level of political competition in a society and the degree of economic liberalization. The above issue ... -
Estudio experimental del efecto de la turbulencia sobre el espectro de tamaño de gotas de nube
(2017)El propósito de este trabajo es estudiar empíricamente el efecto sobre el espectro de tamaños de gotas en una nube cálida, sometida a perturbaciones que afectan el movimiento de la parcela de aire en donde se encuentra. ... -
Explaining coexistence of nitrogen fixing and non-fixing rhizobia in legume-rhizobia mutualism using mathematical modeling
(2017)In the mutualism established between legumes and soil bacteria known as rhizobia, bacteria from soil infect plants roots and reproduce inside root nodules where they fix atmospheric N2 for plant nutrition, receiving ... -
The fractal organization of ultradian rhythms in avian behavior
(2017)Living systems exhibit non-randomly organized biochemical, physiological, and behavioral processes that follow distinctive patterns. In particular, animal behavior displays both fractal dynamics and periodic rhythms yet ... -
The lattice of congruences of a finite line frame
(2017)Let F = <F, R> be a finite Kripke frame. A congruence of F is a bisimulation of F that is also an equivalence relation on F. The set of all congruences of F is a lattice under the inclusion ordering. In this article we ... -
Looking for fairer societies, can hard sciences help? : Comment on “Modeling human behavior in economics and social science” by Marina Dolfin, Leone Leonida and Nisrine Outada
(2017)Comment on "Modeling human behavior in economics and social science" by Marina Dolfin, Leone Leonida and Nisrine Outada. -
A methodology to determine natural radioactivity by γ spectrometry without using calibrated standard samples
(2017)When determining the radioactivity in materials by γ spectra, different processes are involved difficulting the fit. Besides, calibrated standard samples are necessary. In this work we propose a methodology to determine ... -
Una mirada sobre el operativo aprender
(2017)El artículo presenta algunas reflexiones en torno al operativo de evaluación "Aprender". -
Modeling polymeric gels : the role of chain flexibility on the structure of physical gels
(2017)Using molecular dynamics simulations and a simple model for chain molecules we study the gel formation under different conditions. The main characteristic of the model is the short attractive range of the non-bonding ... -
Positivity results for indefinite sublinear elliptic problems via a continuity argument
(2017)We establish a positivity property for a class of semilinear elliptic problems involving indefinite sublinear nonlinearities. Namely, we show that any nontrivial nonnegative solution is positive for a class of problems the ... -
Problem of quantifying quantum correlations with non-commutative discord
(2017)In this work we analyze a non-commutativity measure of quantum correlations recently proposed by Y. Guo [Sci. Rep. 6, 25241 (2016)]. By resorting to a systematic survey of a two-qubit system, we detected an undesirable ... -
Selección de parcelas control para estudios de la dinámica post-incendio : desempeño de rutinas no paramétricas y autorregresivas
(2017)Los regímenes naturales de incendios han sufrido modificaciones; consecuentemente, es indispensable disponer de herramientas robustas para el seguimiento post-fuego de la vegetación. Los satélites de alta resolución temporal ... -
Shedding light on the entropy change found for the transition stage II→stage I of Li-ion storage in graphite
(2017)In order to examine the controversial hypothesis put forward to explain the entropy step experimentally observed for the stage II to stage I transition for lithium intercalation in graphite, a transparent statistical ... -
SiNaRaMe : integración de una red de radares hidro-meteorológicos en latinoamérica
(2017)Pocos países en Latinoamérica poseen radares meteorológicos operativos y, menos aún, han logrado la integración de estos mediante una red, junto a otros instrumentos y sensores remotos para monitoreo hidro-meteorológico. ... -
Structural and magnetic influence of yttrium-for-iron substitution in cobalt ferrite
(2017)Yttrium-substituted cobalt ferrites of nominal composition CoY x Fe 1.98-xO4 , x=0; 0.1; 0.2; 0.3, were prepared using the sol-gel combustion method. A slight iron deficiency in the formulation was designed in order to ... -
Structural and magnetic properties of nanocrystalline Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) synthesized by a mechanochemical route
(2017)Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) powders were prepared by means of a solid acid-base reaction induced by mechanochemical energy. Bi, La and Fe chlorides were high-energy ball-milled with NaOH, yielding a mixture of Bi1-xLaxFeO3 ... -
Structure constrained by metadata in networks of chess players
(2017)Chess is an emblematic sport that stands out because of its age, popularity and complexity. It has served to study human behavior from the perspective of a wide number of disciplines, from cognitive skills such as memory ...
