(Springer, 2020)Simultaneously estimating plasma parameters of the ionosphere presents a problem for the incoherent scatter radar (ISR) technique at altitudes between ~ 130 and ~ 300 km. Different mixtures of ion concentrations and ...
-
(Hindawi, 2020)Nonalcoholic fatty liver disease (NAFLD) is a pathology that contains a broad liver dysfunctions spectrum. These alterations span from noninflammatory isolated steatosis until nonalcoholic steatohepatitis (NASH), a more ...
-
(Cambridge Univ., 2020)It is well understood that a supercritical superprocess is equal in law to a discrete Markov branching process whose genealogy is dressed in a Poissonian way with immigration which initiates subcritical superprocesses. The ...
-
(Elsevier, 2020)While collecting data for estimating discrete-choice models, researchers often encounter missing information in observations. In addition, endogeneity can occur whenever the error term is not independent of the observed ...
-
Assessing nitrogen dioxide (NO2) impact on health preand post-COVID-19 pandemic using IoT in India (Emerald, 2020)Purpose - Corona Virus Disease 2019 (COVID-19) is a deadly virus named after severe acute respiratory syndrome coronavirus 2; it affects the respiratory system of the human and sometimes leads to death. The COVID-19 mainly ...
-
(Cambridge Univ., 2020)Glacier ice thickness is crucial to quantifying water resources in mountain regions, and is an essential input for ice-flow models. Using a surface velocity inversion method, we combine ice thickness measurements with ...
-
(Elsevier, 2020)COVID-19 pandemic has reshaped our world in a timescale much shorter than what we can understand. Particularities of SARS-CoV-2, such as its persistence in surfaces and the lack of a curative treatment or vaccine against ...
-
(Elsevier, 2020)Natural geysers on Earth are uncommon and most of them are clustered in large basins that share common characteristics, specifically, a magmatic heat source, meteoric water supply, and a set of fractures and/or porous rocks ...
-
(Pergamon-Elsevier, 2020)Fracture opening at low differential stress controls maximum sustainable fluid pressure (lambda) within cohesive brittle crust. Standard Andersonian stress states occur when two conditions are met: (1) one of the principal ...
-
(Soc Exploration Geophysicists, 2020)Understanding and monitoring the seismic responses of rock masses to massive mining are crucial for safety and economic viability of ever larger and deeper underground operations. Seismic monitoring can be used to detect ...

(Universidad de Chile, 2020)Un evento de precipitación extrema ocurrió durante la segunda quincena de enero de 2020 en el Desierto de Atacama. Desde Tacna, Perú hasta Iquique, Chile (18-21ºS) las lluvias se prolongaron durante varios días produciendo ...
-
(Universidad de Chile, 2020)El objetivo de este estudio es entender los procesos de internacionalización en educación superior, en particular aquellas características o factores que explican la participación y la intención de participar de estudios ...
-
(EDP Sciences, 2020)Context. Spatially resolved observations of the ionized and molecular gas are critical for understanding the physical processes that govern the interstellar medium (ISM) in galaxies. The observation of starburst systems ...
-
(Oxford University Press, 2020)We present a map of the total intrinsic reddening across similar or equal to 34 deg(2) of the Small Magellanic Cloud (SMC) derived using optical (ugriz) and near-infrared (IR; YJK(s)) spectral energy distributions (SEDs) ...
-
(Universidad de Chile, 2020)El propósito de esta tesis es estudiar como cambiaron las tasas de valorización del Swap Promedio Cámara\footnote{Se abrevian SPC CLP} luego de la incorporación de colaterales en dólares a este producto a mediados del año ...
