Stability of solitary waves in the nonlinear Dirac equation with arbitrary nonlinearity [Article]
(American Physical Society, 2014)
We consider the nonlinear Dirac equation in 1 + 1 dimension with scalar-scalar self interaction g2κ+1(Ψ¯¯¯Ψ)κ+1 and with mass m. Using the exact analytic form for rest frame solitary waves of the form Ψ(x,t)=ψ(x)e−iωt for ...
8-Dehydrosterols induce membrane traffic and autophagy defects through V-ATPase dysfunction in Saccharomyces cerevisae [Article]
8-Dehydrosterols are present in a wide range of biologically relevant situations, from human rare diseases to amine fungicide-treated fungi and crops. However, the molecular bases of their toxicity are still obscure. We ...
Invariant complex structures on 6-nilmanifolds classification, Frölicher spectral sequence and special Hermitian metrics [Article]
We classify invariant complex structures on 6-dimensional nilmanifolds up to equivalence. As an application, the behaviour of the associated Frölicher sequence is studied as well as its relation to the existence of ...
Mental health and quality of life in liver transplant and cirrhotic patients with various etiologies [Article]
(Elsevier/Asociación Española de Psicología Conductual, 2012)
In this study we aimed to: 1) examine whether there were differences in mental health and quality of life of liver transplant recipients according to etiology that led to transplantation (alcoholic cirrhosis, Hepatitis ...
Asymptotic rejection of sinusoidal disturbances based voltage balance control in back-to-back power converters [Article]
This paper addresses the imbalance problem of the dc-link capacitor voltages in the three-level diode-clamped back-to-back power converter. In order to cope with it, a mathematical analysis of the capacitor voltage difference ...
Linear Time Solution to Prime Factorization by Tissue P Systems with Cell Division [Presentation]
(Fénix Editora, 2011)
Prime factorization is useful and crucial for public-key cryptography, and its application in public-key cryptography is possible only because prime factorization has been presumed to be difficult. A polynomial-time ...
General approach for dealing with dynamical systems with spatiotemporal periodicities [Article]
(American Physical Society, 2015)
Dynamical systems often contain oscillatory forces or depend on periodic potentials. Time or space periodicity is reflected in the properties of these systems through a dependence on the parameters of their periodic terms. ...
Familias en riesgo que reciben intervenciones de preservación familiar: Perfil psicosocial de una muestra de los Servicios Sociales Comunitarios de la Diputación de Huelva [Book]
(Diputación de Huelva, Servicio de Publicaciones, 2013)
A mixed formulation for the direct approximation of L2-weighted controls for the linear heat equation [Article]
This paper deals with the numerical computation of null controls for the linear heat equation. The goal is to compute approximations of controls that drive the solution from a prescribed initial state to zero at a given ...
Simultaneous analysis of elastic, breakup, and fusion channels for 6He induced reactions at energies near the coulomb barrier [Article]
(EDP Sciences, 2011)
We present some recent applications of the Continuum-Discretized Coupled-Channels (CDCC) and Coupled-Reaction-Channels (CRC) methods to the study of reactions induced by weakly-bound nuclei on stable targets. The methods ...
