(Springer, 2020)Analyzing December-February (DJF) precipitation in the southern tropical Andes-STA (12 circle S}; > 3000 m.a.s.l) allows revisiting regional atmospheric circulation features accounting for its interannual variability over ...
-
(MDPI, 2020)Due to the long time horizon typically characterizing forest planning, uncertainty plays an important role when developing forest management plans. Especially important is the uncertainty related to recently human-induced ...
-
(Taylor & Francis, 2020)Medium-term development planning of underground mines requires scheduling multiple activities to comply with long-term milestones, and to obtain a time span as short as possible. However, the planning must also respect the ...

-
(EDP Sciences, 2020)Context. The Upper-Scorpius association (5-11 Myr) contains a unique population of low-mass (M <= 30M(Jup)) brown dwarfs either free-floating, forming wide pairs, or on wide orbits around solar-type and massive stars. The ...
-
(IOP, 2020)We identify 1901 galaxy clusters (N-g >= 2) with the VoML+G algorithm (Paper I) on the Two-Degree Field Galaxy Redshift Survey. We present the 341 clusters with at least 10 galaxies that are within 0.009 < z < 0.14 (the ...
-
(IOP Publishing, 2020)We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of similar to 0.'' (40au), including observations with the Very ...
-
(MDPI, 2020)High-resolution mineral characterization performed on mine material from a giant porphyry copper deposit shows that critical and precious metals, such as cobalt, lanthanum, gold, silver, and tellurium, are concentrated in ...
-
(MDPI, 2020)Active subaerial geothermal systems are regarded as modern analogues of low- to intermediate-sulfidation epithermal Au–Ag deposits, where minor amounts of Cu are mostly present as chalcopyrite. Although trace element ...
-
(Asociación Española de Ciencia Política y de la Administración, 2020)El presidencialismo ha sido ampliamente estudiado en América Latina. Sin embargo, su impacto en la elaboración de políticas públicas permanece prácticamente inexplorado. Este artículo analiza el papel e influencia de los ...
-
(European Mathematical Society, 2020)Let Omega be a smooth bounded domain in R-n, n >= 5. We consider the classical semilinear heat equation at the critical Sobolev exponent. ut =Delta u + un+2/n-2 in Omega x (0, infinity), u = 0 on partial derivative Omega ...
-
(Springer, 2020)A classical problem for the two-dimensional Euler flow for an incompressible fluid confined to a smooth domain is that of finding regular solutions with highly concentrated vorticities around N moving vortices. The formal ...
-
(The Geological Society of America, 2020)To investigate the dynamic response of the outer accretionary prism up-dip from the patch of greatest slip during the 2010 M-w 8.8 Maule earthquake (Chile), 10 ocean-bottom seismometers (OBSs) were deployed from May 2012 ...
-
(Elsevier, 2020)The SART (Sulfidization, Acidification, Recycling and Thickening) process has been successfully installed to recover cyanide and copper in seven worldwide gold cyanidation plants in the last 15 years. This technology has ...
-
(SAGE, 2020)This article conducts a comparative study on the effectiveness of ventilation to mitigate blasting effects on spherical chambers subjected to internal detonations of high explosives through finite element analysis using ...
-
(Elsevier, 2020)The Valle Fertil-La Huerta batholith is a differentially tilted, compositionally stacked, calc-alkaline plutonic sequence in the central Famatinian arc of Argentina. It consists of two major lithologic units: these are (1) ...
-
(Elsevier, 2020)This paper evaluates the potential of water-side economizers in the refrigeration system of data centers under different climate conditions. Due to the wide range of conditions along the country (Desert, Mediterranean, ...
-
(Universidad de Chile, 2020)Escasos antecedentes se tienen sobre la composición mineralógica y geoquímica del fondo marino de la zona económica exclusiva de Chile (ZEE). En este trabajo se analizó la composición de los sedimentos marinos entre la ...
-
(Universidad de Chile, 2020)Debido a los avances tecnológicos que han experimentado los mercados financieros en las últimas décadas, hoy las transacciones de acciones equivalentes se distribuyen a través de múltiples bolsas con libros de órdenes ...
-
(Universidad de Chile, 2020)This thesis has two main purposes: first, we shall compare continuous and discrete trajectories associated to a differential inclusion governed by the sum of a maximally monotone operator with a cocoercive operator and ...
