(MDPI, 2020)The flow between two parallel plates driven by a pulsatile pressure gradient was studied analytically with a second-order velocity expansion. The resulting velocity distribution was compared with a numerical solution of ...
-
(Elsevier, 2013)In this paper we are interested in propagation phenomena for nonlocal reaction–diffusion equations of the type: ∂u ∂t = J ∗ u −u+ f (x,u) t ∈ R, x ∈ RN, where J is a probability density and f is a KPP nonlinearity ...
-
(Amer Inst. Physis, 2020)Nonlinear pulse propagation is a major feature in continuously extended excitable systems. The persistence of this phenomenon in coupled excitable systems is expected. Here, we investigate theoretically the propagation of ...
-
(2014)Carbon nanodot arrays (CNA) are grown on silicon substrates by using pulsed laser deposition and porous alumina membranes as a mask. The masks are grown directly on silicon substrates, thus allowing the fabrication of ...

(Universidad de Chile, 2016)En la presente memoria se estudia la propiedad de regularidad asintótica para una variante de la iteración de \textit{Krasnoselskii-Mann} en un espacio de Banach general. Este problema está enmarcado en la teoría métrica ...

(Wiley, 2017)BACKGROUND: Gene therapy is a potent alternative for long-lasting inhibition of alcohol consumption. This study compares the purification of a recombinant adenoviral vector serotype 5 (rAdV5) for use in gene therapy against ...
-
(Elsevier, 2017)Phlorotannins are secondary metabolites produced by brown seaweed, which are known for their nutraceutical and pharmacological properties. The aim of this work was to determine the type of macroporous resin and the ...
-
(2013-05)We study the wavefront solutions of the scalar reaction-diffusion equations ut(t, x) = Δu(t, x)-u(t, x)+g(u(t-h,x)), with monotone reaction term g : ℝ+ → ℝ+ and h > 0. We are mostly interested in the situation when the ...
-
(IOP Publishing, 2016)The purpose of this review article is to push amplitude equations as far as possible from threshold. We focus on the Stuart-Landau amplitude equation describing the supercritical Hopf bifurcation of the flow in the wake ...
-
(WILEY-BLACKWELL, 2016)Following the trend of studies that investigate microbial ecosystems using different metagenomic techniques, we propose a new integrative systems ecology approach that aims to decipher functional roles within a consortium ...
-
(Public Library of Science, 2019)The huemul (Hippocamelus bisulcus) is an endangered cervid endemic to southern Argentina and Chile. Here we report foot lesions in 24 huemul from Bernardo O’Higgins National Park, Chile, between 2005 and 2010. Affected ...
-
(Universidad de Chile, 2012)Chile es el segundo país en Sudamérica con mayor cantidad de reclusos, presentando una tasa de 296 internos por cada 100 mil habitantes, esta cifra da cuenta de la crisis por la que atraviesa el sistema penitenciario hace ...
-
(Elsevier, 2013)Porphyry copper deposits are currently the world’s largest source of copper and molybdenum, and are also among the largest reservoirs of gold in the upper crust. Despite the fact that pyrite is a ubiquitous mineral phase ...
-
(Elsevier, 2017)Better constrained pressure-temperature (P-T) histories of metamorphic complexes along the Andean continental margin are important for understanding the late Paleozoic and Mesozoic tectonic evolution of the southwestern margin ...
-
(IOP Publishing, 2015)We present polarization observations of two Galactic plane fields centered on Galactic coordinates (l, b) = (0 degrees, 0 degrees) and (329 degrees, 0 degrees) at both Q (43 GHz) and W bands (95 GHz), covering between 301 ...
-
(Elsevier, 2016)We prove sharp Holder continuity and an estimate of rupture sets for sequences of solutions of the following nonlinear problem with negative exponent Delta u =1/u(p) in Omega, p > 1. As a consequence, we prove the ...
-
(SPRINGER, 2006-01)In a series of papers the question of uniqueness of radial ground states of the equation Delta u + f(u) = 0 and of various related equations has been studied. It is remarkable that throughout this work (except in very ...
-
(American Institute of Mathematical Sciences, 2019)This paper is concerned with the qualitative properties of the solutions of mixed integro-differential equation (equation presented) with N ≥ 1, M ≥ 1 and ϵ 2 (0; 1). We study decay and symmetry properties of the solutions ...
