Con el surgimiento y el desarrollo de Internet la tecnología se ha convertido en la protagonista de las sociedades desarrolladas presentando un panorama el que se cruza el plano de lo educativo y lo tecnológico. En el ...

The main goal of this paper is to present a new result concerning controllability of the time-dependent Navier-Stokes equations. Here, the control variable is the trace of the velocity field on a "small" part of the boundary. ...

The goal of this work is to study the forward dynamics of positive solutions for the nonautonomous logistic equation ut − ∆u = λu − b(t)up, with p > 1, b(t) > 0, for all t ∈ R, limt→∞ b(t) = 0. While the pullback asymptotic ...

El trabajo autónomo económicamente dependiente como modalidad contractual específica dentro de la regulación general contenida dentro del Estatuto del Trabajo Autónomo de 2007 comportó en su momento una significativa novedad ...

A deformed version of the vibron model for diatomic molecules is constructed. Both the O(4) and U(3) dynamical symmetries of the model are rewritten, using the concept of complementary subalgebras, in a more convenient ...

Excretion of amino acids by yeast cells was reported long ago but has not been characterized in molecular terms. It is typically favored by overproduction of the amino acid and/or impairment of its uptake. Here we describe ...
