Forwards and pullback behaviour of a non-autonomous Lotka-Volterra system [Article]
(IOPscience, 2003-07)
Lotka-Volterra systems have been extensively studied by many authors, both in the autonomous and non-autonomous cases. In previous papers the time asymptotic behaviour as t → ∞ has been considered. In this paper we also ...
Existence and uniqueness of positive solution of a logistic equation with nonlinear gradient term [Article]
(Cambridge University Press, 2007-06)
The main goal of this work is to study the existence and uniqueness of positive solution of a logistic equation including a nonlinear gradient term. In particular, we use local and global bifurcation together with some ...
Molecular Computation Models in ACL2: a Simulation of Lipton’s Experiment Solving SAT [Presentation]
(2002)
In this paper we present an ACL2 formalization of a molecular computing model: Adleman’s restricted model [2]. This is a first step to formalize unconventional models of computation in ACL2. As an application of this ...
Local strong solution for the incompressible Korteweg model [Article]
(Elsevier, 2006-02)
We consider a Navier-Stokes type system with a Korteweg stress tensor, coupled with a concentration equation without diffusion. We give a result concerning the local in time existence (and uniqueness) of strong solution ...
Un estudio muestra la eficacia de composts de residuos agroindustriales para reducir enfermedades de las plantas [Article]
(Interempresas media, 2012)
Algunos residuos agroindustriales ya compostados y usados como sustratos pueden presentar supresividad a distintas enfermedades de las plantas. Algunos de estos sustratos son el compost de corcho (usado solo o mezclado con ...
Algebraic computation of some intersection D-modules [Article]
(Springer, 2006)
Let X be a complex analytic manifold, D ⊂ X a locally quasi-homogeneous free divisor, E an integrable logarithmic connection with respect to D and L the local system of the horizontal sections of E on X − D. In this ...
Latent inhibition as a model of schizophrenia: from learning to psychopathology [Article]
(Asociación de Análisis del Comportamiento, 2003)
En la esquizofrenia los procesos atencionales pueden encontrarse alterados y estar a la base de otra sintomatología como los delirios y las alucinaciones. Una de las aproximaciones experimentales al estudio de los procesos ...
Pavlov in America: a heterodox approach to the study of his influence [Article]
(Universidad Complutense, 2003)
En el presente trabajo se realiza un análisis crítico de la influencia de Pavlov que va más allá de su visión convencional: aquélla que reduce su influencia en la psicología americana al conductismo de Watson y Hull. Para ...
Exact numerical solutions for dark waves on the discrete nonlinear Schrödinger equation [Article]
(American Physical Society, 2005)
In this paper we study numerically existence and stability of exact dark waves on the (nonintegrable) discrete nonlinear Schrödinger equation for a finite one-dimensional lattice. These are solutions that bifurcate from ...
Study of the optimal harvesting control for an elliptic problem with slow diffusion [Article]
(Sociedade Brasileira de Matemática, 2007)
In this paper our aim is to present a survey of known results of an optimal control problem with concave non-quadratic cost functional and a state equation arising from population dynamics. First, we study in detail the ...
