(Elsevier, 2018)This paper presents a new algorithm to find under-dense regions called voids inside a 2D point set. The algorithm starts from terminal-edges (local longest-edges) in a Delaunay triangulation and builds the largest possible ...
-
(Universidad de Chile, 2017)En esta tesis doctoral se construyen soluciones rotacionalmente simétricas de la ecuación de Cahn-Hilliard en $ \R{^d} $ y se estudian sus propiedades de estabilidad. En el Capítulo \ref{ch1} se presenta la ecuación de ...

(Universidad de Chile, 2016)En el campo de la cosmología, los vacíos son regiones del espacio cuya densidad es nota- blemente menor que la densidad de fondo, abarcando distancias en el rango de 20 50 Mpc/h (1 Mpc/h ∼ 2,10 × 1019 km). Los primeros ...
-
(Universidad de Chile, 2021)En simulaciones de fluidos basadas en el método smoothed particle hydrodynamics (SPH), la operación para encontrar los vecinos dado un cierto umbral fijo de cada partícula es la operación más costosa que debe realizarse ...
-
(Springer, 2017)We construct Delaunay-type solutions for the fractional Yamabe problem with an isolated singularity(Formula Presented.)We follow a variational approach, in which the key is the computation of the fractional Laplacian in ...
-
(1965)-In the most direct method for measuring correlation functions with an analog computer a delay must be simulated. Since a lumped parameter system is used, we can only hope to approximate this delay. We intentionally exclude ...

(Sociedad Medica de Santiago, 2015)© 2015, Sociedad Medica de Santiago. All rights reserved. Background: Early diagnosis is fundamental in patients with Parkinson’s disease (PD) to improve their quality of life. Aim: To determine the latency in the diagnosis ...
-
(SPRINGER, 2006-09)This paper is devoted to the study of a nonconvex perturbed sweeping process with time delay in the infinite dimensional setting. On the one hand, the moving subset involved is assumed to be prox-regular and to move in an ...
-
(NLM (Medline), 2019)BACKGROUND: Postponement of motherhood is one of the most striking sociodemographic changes of modernity. AIM: To evaluate the age of primiparous women giving birth at a public hospital in Santiago, Chile. MATERIAL AND ...
-
(2010)Objectives: Ischemic preconditioning (IP) affords resistance to liver ischemia-reperfusion (IR) injury, providing an early phase of protection. Development of delayed IP against IR injury was assessed using partial IR in ...
-
(Blacwell Munksgaard, 2003-07)Background, aims: Neutrophil cells constitute the first defense barrier against the oral bacterial challenge in the periodontium. Reduction of neutrophils could impair this response against periopathogenic bacteria such ...
-
(Elsevier, 2018-06)OBJECTIVE To compare outcomes with early vs delayed reconstruction following pelvic fracture urethral injury (PFUI) to determine if a traditional 3-month delay is necessary. This delay has been advocated to allow resolution ...
-
(National Stroke Association, 2013)Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is a chorioretinal disease that causes acute binocular visual disturbance with characteristic funduscopic lesions at the level of the retinal pigment ...
-
(Econometric Society, 2021)Learning is crucial to organizational decision making but often needs to be delegated. We examine a dynamic delegation problem where a principal decides on a project with uncertain profitability. A biased agent, who is ...
-
(Universidad de Chile, 2012)Este trabajo estudia la literatura de toma de decisiones en ambientes con informaci ón asim étrica y sin transferencias monetarias. Quien debe tomar la decisión, llamado el principal, carece de información relevante acerca ...
-
(Universidad de Chile, 2006)La bicicleta sirve para pensar, es una buena terapia introspectiva, para ordenar nuestro mundo interno y que con otras actividades es difícil de hacer. La bicicleta permite este auto análisis, de hecho uno se despeja, se ...
-
(Amer Chemical Society, 2016)The protective effect of proanthocyanidin-containing polyphenol extracts from apples, avocados, cranberries, grapes, or proanthocyanidin microbial metabolites was evaluated in colonic epithelial cells exposed to p-cresol, ...
-
(Elsevier, 2015)p-Cresol that is produced by the intestinal microbiota horn the amino acid tyrosine is found at millimolar concentrations in the human feces. The effects of this metabolite On colonic epithelial cells were tested in this ...
