Aplicación de simulación con dinámica molecular al cálculo de energía relativa de borde de grano en hielo
(2016)En este trabajo se calculó la energía de los bordes de grano en hielo y la energía superficial del hielo mediante simulaciones de dinámica molecular en muestras bicristalinas con bordes de grano simétricos en función de ... -
Internal - External stimulus competition in a system of interacting moving particles : persuasion vs propaganda
(2015)We propose a general nonlinear analytical framework to study the effect of an external stimulus in the internal state of a population of moving particles. This novel scheme allows us to study a broad range of excitation ... -
Normal holonomy of orbits and Veronese submanifolds
(2015)It was conjectured, twenty years ago, the following result that would generalize the so-called rank rigidity theorem for homogeneous Euclidean submanifolds: let Mn, n ≥ 2, be a full and irreducible homogeneous submanifold ... -
Narrow-band search of continuous gravitational-wave signals from Crab and Vela pulsars in Virgo VSR4 data
(2015)In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In order to take into account a possible small ... -
Plasmatic biochemical variables associated with polymorphisms in the endothelin-1 and endothelin-1 receptor a genes in hypertensive patients : pilot study
(2016)Aims: Endothelin-1 (ET-1) is a potent vasoconstrictive peptide, and its activity is mediated by the type A receptor (EDNRA). This action may play a significant role in the etiology of hypertension. There are different works ... -
Kerma and photons absorbed-dose from Ir-192 HDR seeds
(2014)Precise calculations of absorbed dose (AD) are a difficult task involving physical phenomena such as emission, transport, and absorption of radiation. We used the Monte Carlo method to calculate Kerma as well as AD in water ... -
Strong cosmic censorship and Misner spacetime
(2015)Misner spacetime is among the simplest solutions of Einstein's equation that exhibits a Cauchy horizon with a smooth extension beyond it. Besides violating strong cosmic censorship, this extension contains closed timelike ... -
Neutrinos
(2015)En este artículo vamos a repasar brevemente el Modelo Estándar de Partículas, luego haremos una revisión cronológica del descubrimiento del neutrino. Por último mencionaremos el Observatorio de Neutrinos de Sudbury y ... -
Examples of extensions of hopf algebras
(2015)We give some examples of, and raise some questions on, extensions of semisimple Hopf algebras. -
Adapting a Fourier pseudospectral method to Dirichlet boundary conditions for Rayleigh–Bénard convection
(2015)We present the adaptation to non–free boundary conditions of a pseudospectral method based on the (complex) Fourier transform. The method is applied to the numerical integration of the Oberbeck–Boussinesq equations in a ... -
Invariants of complex structures on nilmanifolds
(2015)Let (N, J) be a simply connected 2n-dimensional nilpotent Lie group endowed with an invariant complex structure. We define a left invariant Riemannian metric on N compatible with J to be minimal, if it minimizes the norm ... -
Time and band limiting for matrix valued functions, an example
(2015)The main purpose of this paper is to extend to a situation involving matrix valued orthogonal polynomials and spherical functions, a result that traces its origin and its importance to work of Claude Shannon in laying the ... -
La realidad de los átomos
(2015)En este trabajo nos proponemos reconsiderar, desde una perspectiva histórica, la contribución de Albert Einstein a la de la teoría molecular de la realidad con sus trabajos sobre el movimiento Browniano. -
Reaction rate in an evanescent random walkers system
(2015)Diffusion mediated reaction models are particularly ubiquitous in the description of phys-ical, chemical or biological processes. The random walk schema is a useful tool for formu-lating these models. Recently, evanescent ... -
Proving correctness of a compiler using step-indexed logical relations
(2016)In this paper we prove the correctness of a compiler for a call-by-name language using step-indexed logical relations and biorthogonality. The source language is an extension of the simply typed lambda-calculus with ... -
Educación matemática de jóvenes y adultos : la complejidad de la enseñanza en una oferta semipresencial
(2014)Este artículo tiene como objetivo presentar hallazgos de una investigación referida a la enseñanza de saberes matemáticos en la modalidad de Educación Permanente de Jóvenes y Adultos. Este estudio tuvo como objeto analizar ... -
A performance evaluation of oscillation based test in continuous time filters
(2014)This work evaluates the ability of OBT for detecting parametric faults in continuous-time filters. To this end, we adopt two filters with quite different topologies as cases of study and a previously reported statistical ... -
A high performance biometric system based on image morphological analysis
(2014)At present, many of the algorithms used and proposed for digital imaging biometric systems are based on mathematical complex models, and this fact is directly related to the performance of any computer implementation of ... -
Geometric formulation of the uncertainty principle
(2014)A geometric approach to formulate the uncertainty principle between quantum observables acting on an N-dimensional Hilbert space is proposed. We consider the fidelity between a density operator associated with a quantum ... -
Pensar y calcular
(2014)Pensamos. Y pensamos que pensar es una de las características distintivas de los bípedos implumes, distinción que ha provocado un salto evolutivo incalculable. A veces tratamos de calcular distintas cosas, por ejemplo ...
