(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 ...

(Grupo Ars XXI de Comunicacion, S.L., 2019)© 2018 Elsevier España, S.L.U. y Asociación Española de Logopedia, Foniatría y Audiología e Iberoamericana de Fonoaudiología Introduction: Dysarthria is an acquired motor speech disorder of neurological origin. Usually ...
-
(Korean Society for Parasitology and Tropical Medicine, 2019)In the indeterminate chronic period of Chagas disease (ChD) the treatment has not been conclusive, because the serological negativization requires many years. This study aims to evaluate the efficacy of nifurtimox (NF) in ...
-
(Copernicus Publications, 2015)We present surface mass balance simulations of the Southern Patagonia Icefield (SPI) driven by downscaled reanalysis data. The simulations were evaluated and interpreted using geodetic mass balances, measured point ...
-
(Blackwell Publishing Ltd, 2019)Forest insect outbreaks are one of the major biotic disturbances on natural and artificial landscapes. Although abundant literature of insect outbreaks exists in the Northern Hemisphere, studies for the Southern Hemisphere ...
-
(INST ENGINEERING TECHNOLOGY-IET, 2016)In this study, the economic benefits of using a probabilistic-dynamic approach (PDA) in the quantification of operating reserves are investigated and compared with more traditional quantification rules in power systems ...

-
(Springer Science+Business Media, 2014)Lake Villarrica, located in south central Chile, has amaximum depth of 167mand amaximum fetch of about 20 km.The lake is monomictic, with a seasonal thermocline located at a depth of approximately 20 m. Field data show ...
-
(Universidad de Chile, 2022)El método de gráfico de estabilidad de Mathews es usado ampliamente para el diseño de minas subterráneas de caserones abiertos. Como método empírico, utiliza variables de entrada como la calidad del macizo rocoso y factores ...
-
(Springer, 2016)This work addresses the problem of delineating the spatial layout of ten rock type domains in an iron ore body and of assessing the uncertainty in the domain boundaries. A stochastic approach is proposed to this end, based ...
-
(Springer-Verlag Wien, 2018)Wet muck entry is one of the major geotechnical risks associated with long-term production goals in cave mining. The objective of this research is to quantify the effect of the main risk variables related to wet muck entry ...
-
(E-JC, 2015)Given a one-factorization F of the complete bipartite graph Kn;n, let pf(F) de- note the number of Hamiltonian cycles obtained by taking pairwise unions of perfect matchings in F. Let pf(n) be the maximum of pf(F) over ...
-
(Scuola Normale Superiore, 2020)We study periodic wind-tree models, billiards in the plane endowed with Z2-periodically located identical connected symmetric right-angled obstacles. We exhibit e ective asymptotic formulas for the number of periodic billiard ...
-
(Universidad de Chile, 2021)Esta tesis se concentra en el estudio de modelos estocásticos de poblaciones compuestas de individuos interactuando entre ellos o con su medio. En una primera parte consideramos sistemas de difusión cruzada para dos ...
-
(Hebrew University Magnes Press, 2018-06)We provide various counter examples for quantitative multiple recurrence problems for systems with more than one transformation. We show that:There exists an ergodic system (X,X, mu,T (1), T (2)) with two commuting ...
-
(Inst Mathematical Statistics, 2016)We study a class of one-dimensional particle systems with true (Bird type) binary interactions, which includes Kac's model of the Boltzmann equation and nonlinear equations for the evolution of wealth distribution arising ...
-
(Springer, 2018)We prove propagation of chaos at explicit polynomial rates in Wasserstein distance for Kac's N-particle system associated with the spatially homogeneous Boltzmann equation for Maxwell molecules. Our approach is mainly based ...
