(Blackwell Publishing Ltd, 2019)©2018. American Geophysical Union. All Rights Reserved.Based on a large data set of local body wave travel times, we determined the first 3-D model of azimuthal P wave anisotropic tomography of northern Chile in order to ...
-
(2015)In this document, we study the scope of the following graph model: each vertex is assigned to a box in Rd and to a representative element that belongs to that box. Two vertices are connected by an edge if and only if its ...
-
(Royal Astronomical Society, 2015)MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) is a 6-yr Sloan Digital Sky Survey (SDSS-IV) survey that will obtain spatially resolved spectroscopy from 3600 to 10 300 Å for a representative sample of over ...
-
(Universidad de Chile, 2016)Un conjunto de vértices de un grafo se dice convexo si contiene a los vértices de todos los caminos mínimos entre sus vértices. El problema de determinar si un grafo tiene una partición en p conjuntos convexos es NP-completo, ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-08)Pressure and temperature metamorphic conditions were determined for K-white mica and chlorite in metapelites from the eastern Andean metamorphic complex (EAMC) and from the Chonos metamorphic complex (CMC) of southern ...
-
(SERVICIO NACIONAL GEOLOGIA MINERVA, 2008-07)In the Guarguaraz Complex of the Argentine Frontal Cordillera (latitude 33.3°S) serpentinite lenses, metabasites, and garnet-bearing metasedimentary rocks occur. The corresponding Devonian metamorphic event was assigned ...
-
(ELSEVIER, 2008-03)The geodynamic evolution of the proto-Andean margin of Gondwana during the Paleozoic was characterized by repeated subduction processes associated with the docking of several terranes, including the Cuyania-Precordillera ...
-
(Elsevier B.V., 2019)© 2018 Elsevier B.V. In mammals, the cochlear sensory epithelium becomes quiescent early during development. After the first postnatal week, there is no cell replacement or proliferation, and severe damage leads to permanent ...
-
(Springer Berlin Heidelberg, 2008-01)In this paper we propose a distributed meta-index using a peer-to-peer protocol to allow spatio-temporal queries of moving objects on a large set of distributed database servers.We present distribution and fault tolerance ...
-
(INFORMS, 2010-03)We describe a model examining how a firm might choose the package size and price for a product that deteriorates over time. Our model considers four factors: (1) the usable life of the product, (2) the rates at which ...
-
(Universidad de Chile, 2014)Los sistemas de transmisión de energía eléctrica están destinados a conectar a los agentes productores con los consumidores, de modo que las transacciones se lleven a cabo. En el mercado eléctrico chileno, la ley asegura ...
-
(Universidad de Chile, 2022)Desde el proceso de liberalización del sistema eléctrico que experimentaron múltiples países a finales del siglo XX, diversas han sido las alternativas que se tomaron para enfrentar el problema de contar con un sistema ...
-
(Universidad de Chile, 2023)En los grupos cazadores-recolectores del Pleistoceno Tardío-Holoceno Temprano (12.500-10.000 años cal. AP) de la Puna Meridional del Desierto de Atacama (Región de Atacama, 26°-28°S) se evidencia el primer acercamiento del ...
-
(Elsevier, 2019)Fault zone permeability and the real 3D-spatial distribution of the fault-related fracture networks are critical in the assessment of fault zones behavior for fluids. The study of the real 3D-spatial distribution of the ...
-
(Elsevier, 2018-10)The Cretaceous black shales of Colombia are among the most important successions in the north of South America and have attracted the attention of many geoscientists and exploration companies over the last few decades, ...
-
(Universidad de Chile, 2010)Un conjunto de complejos morrénicos se distribuyen desde el margen este de la Cuenca de Drenaje de Torres del Paine hasta las cercanías del margen actual de los Campos de Hielo Patagónicos. Regionalmente se reconocen en ...
-
(Mineralogical Soc. Amer., 2015)Supergene metal deposits host a comprehensive record of climate-driven geochemical reactions that may span the entire Cenozoic. Products of these reactions can be dated by a variety of radiogenic isotopic methods, such as ...
-
(Universidad de Chile, 2018)La bahía de Guanaqueros (30°S) se ubica en la costa semiárida de Chile, que se caracteriza por un clima transicional entre el clima hiperárido del desierto de Atacama y el clima mediterráneo de la zona central de Chile. ...
-
(Elsevier, 2014)The Illapel Plutonic Complex (IPC), located in the Coastal Range of central Chile (31 e33 S), is composed of different lithologies, ranging from gabbros to trondhjemites, including diorites, tonalites and granodiorites. U/Pb ...
-
(Elsevier, 2011)Ultraviolet, optical, and near-infrared photometry and optical spectroscopy of the broad-lined Type Ic supernova (SN) 2009bb are presented, following the flux evolution from -10 to +285 days past B-band maximum. Thanks to ...
