(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 ...

(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 ...

(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 ...

(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 ...
