Stabilization of a class of biomedical systems via stability preservation
(2008)"We present a method for stabilization of a class of nonlinear systems. The notion of stability preservation is exploited to prove that a transformation allows to find a stabilizer. The nonlinear systems have uncontrollable ... -
Electronic and magnetic properties of Co and Ni impurities in Cu wires: first-principles investigation of local moment formation in one dimension
(2010)"The local moment formation in one-dimensional (1D) systems is investigated in the framework of a generalized gradient approximation to density-functional theory (DFT). The electronic and magnetic properties of Co and Ni ... -
Magnetism of small Cr clusters: interplay between structure, magnetic order, and electron correlations
(2010)"The magnetic properties of small Cr-N clusters (N <= 6) are investigated in the framework of density-functional theory. The interplay between electron correlations, cluster structure, and magnetic order is quantified by ... -

Vesicle motion during sustained exocytosis in chromaffin cells: numerical model based on amperometric measurements
(2015)"Chromaffin cells release catecholamines by exocytosis, a process that includes vesicle docking, priming and fusion. Although all these steps have been intensively studied, some aspects of their mechanisms, particularly ... -
Pattern formation by two precipitated species during solvent evaporation
(2008)"We investigate the pattern formation produced by precipitated species during solvent evaporation through the numerical solution of a set of partial differential equations that account for the mechanisms of evaporation, ... -
Multiscroll attractors by switching systems
(2010)"In this paper, we present a class of three-dimensional dynamical systems having multiscrolls which we call unstable dissipative systems (UDSs). The UDSs are dissipative in one of its components but unstable in the other ... -
Stability of gain scheduling control for aircraft with highly nonlinear behavior
(Hindawi, 2014)"The main goal of this work is to study the stability properties of an aircraft with nonlinear behavior, controlled using a gain scheduled approach. An output feedback is proposed which is able to guarantee asymptotical ... -
Robust switched predictive braking control for rollover prevention in wheeled vehicles
(Hindawi, 2014)"The aim of this paper is to propose a differential braking rollover mitigation strategy for wheeled vehicles. The strategy makes use of a polytopic (piecewise linear) description of the vehicle and includes translational ... -
A different three-port DC/DC converter for standalone PV system
(Hindawi, 2014)"A three-port converter suitable for standalone applications is proposed in this paper. Each port is used for specific input or output, and its functions depend on the port; they are the renewable source, the battery set, ... -
Maximum power point tracking based on sliding mode control
(Hindawi, 2015)"Solar panels, which have become a good choice, are used to generate and supply electricity in commercial and residential applications. This generated power starts with the solar cells, which have a complex relationship ... -

A bounded positive nonlinear PI controller for double-pipe heat exchangers
(2012)"In this work, temperature regulation of double-pipe heat exchangers is considered. The positive (unidirectional) and bounded features of the flow rate input variable are taken into account in the analysis. As a result, a ... -
Nonlinear filtering preserves chaotic synchronization via master-slave system
(Hindawi, 2013)"We present a study on a class of interconnected nonlinear systems and give some criteria for them to behave like a filter. Some chaotic systems present this kind of interconnected nonlinear structure, which enables the ... -
Análisis in vitro del péptido antiviral HRA2pl producido en tabaco, contra Ortopneumovirus y Rubulavirus humanos
(2018-02)"Las infecciones respiratorias agudas (IRA’s) representan un importante problema de salud ya que ocupan el segundo lugar a nivel mundial de morbimortalidad en niños menores de 5 años. Los principales agentes causales son ... -
Identificación de procesos hidrogeoquímicos aplicando modelación inversa en el acuífero Soconusco, Chiapas
(2017-02)"La región del Soconusco en Chiapas, México, posee como actividad económica primordial del sector agrícola, se abastece de agua de pozos y norias. El presente trabajo consistió en realizar caracterización hidrogeoquímica ... -
Efecto elastocalórico en una aleación Ni-Fe-Ga-Mn anisotrópica elaborada por sinterizado por descarga de plasma (SPS)
(2018-02)"Algunas aleaciones del sistema Ni-fe-Ga-Mn presentan transformación martensítica en el intervalo de temperatura ambiente. Las temperaturas de transición se pueden modificar dependiendo de la composición y metodologías de ... -
Producción de biohidrógeno a partir de paja de trigo y podas de jatrofa con extracción in situ
(2018-01)"El uso intensivo de los combustibles fósiles genera la necesidad de explorar nuevas fuentes de energía. Una de las más importantes es el hidrógeno, el cual puede ser producido de forma biológica, a partir de residuos ... -
Caracterización de la sobreexpresión del gen WRKY2 de Arabidopsis thaliana en respuesta al estrés abiótico
(2018-01)"Las proteínas WRKY son importantes factores de transcripción (FTs) involucrados en diversos procesos en plantas como crecimiento, desarrollo, estrés biótico y abiótico. En la planta modelo Arabidopsis thaliana existen ... -
Caracterización de bioaerosoles emitidos en biofiltros durante el tratamiento de COV´s por citometría de flujo
(2018-01)"Se monitoreó y evaluó un sistema de biofiltración alimentado con vapores de acetato de etilo y tolueno por 180 días. Durante este periodo se estudiaron los efectos de la variación de carga y paros de alimentación de un ...
