(Sociedad Médica Santiago: SMS-Chile, 2020)The highest organ donation rate in Chile was 10 donors per million population in 2017, which is low compared with other countries. Local experts attribute the low rate to population's lack of education and generosity, ...
-
(Universidad Autónoma de Barcelona, 2020)Child policies are a relevant area of study in public policy analysis, where the values, ideologies and situational contexts that establish the symbolic orientation of such policies and the state play a central role. Based ...

(Cambridge University Press, 2018)We consider the parabolic one-dimensional Allen-Cahn equation ut = uxx + u(1-u2), (x, t) R x (-0]. The steady state w(x) = tanh(x/2) connects, as a 'transition layer', the stable phases-1 and +1. We construct a solution u ...

(Elsevier Science BV, 2018)We consider the parabolic Allen Cahn equation in R-n, n >= 2, u(t) = Delta u + (1 - u(2))u in R-n x (-infinity, 0]. We construct an ancient radially symmetric solution u(x, t) with any given number k of transition ...
-
(American Geophysical Union, 2020)The southern Central Andes recorded retroarc shortening, basin evolution, and magmatic arc migration during Neogene changes in subduction. At 31-33 degrees S, above the modern flat-slab segment, spatial and temporal linkages ...
-
(Macmillan Publishers Limited, 2013-04-28)Segmentation can influence the extent of earthquake rupture and event magnitude(1): large megathrust earthquakes result from total rupture of relatively continuous segments of the subduction interface(2-5). Segmentation ...
-
(ELSEVIER SCIENCE BV, 2005-06)Sr-Nd isotopic analyses on some mantle xenolith samples from the Northern, Southern and Austral Andean volcanic zones exhibit radiogenic Sr enrichment without dramatic changing of the Nd isotopic composition. This anomalous ...

(Frontiers Media S.A., 2019)Copyright © 2019 Mondaca-Ruff, Riquelme, Quiroga, Norambuena-Soto, Sanhueza-Olivares, Villar-Fincheira, Hernández-Díaz, Cancino-Arenas, San Martin, García, Lavandero and Chiong.Hypertension is a disease associated to ...
-
(Hindawi, 2013)We use an extended version of the standard tunnelingmodel to explain the anisotropic sound absorption in decagonal quasicrystals. The glassy properties are determined by an ensemble of two level systems (TLSs), arbitrarily ...
-
(Elsevier, 2020)A detailed annual performance and thermoeconomic analysis of a Concentrated Solar Power plant coupled to a Photovoltaic and a Multi-Effect Distillation plants (CSP + PV + MED) were performed using an extensive methodology ...
-
(EDP Science, 2020)We present high-resolution millimeter continuum ALMA observations of the disks around the T Tauri stars LkCa 15 and 2MASS J16100501-2132318 (hereafter, J1610). These transition disks host dust-depleted inner regions, which ...
-
(Blackwell, 2012)Experimental results obtained with the 449-MHz Poker Flat Incoherent Scatter Radar (PFISR) show unusual features in both the ion line and plasma line measurements during an auroral breakup event. The features are a greatly ...
-
(IOP PUBLISHING LTD, 2009-01-10)We present evidence for anomalous microwave emission in the RCW175 H II region. Motivated by 33 GHz 13' resolution data from the Very Small Array (VSA), we observed RCW175 at 31 GHz with the Cosmic Background Imager ( CBI) ...
-
(UNIV CHICAGO PRESS, 2004-03-10)A by-product of experiments designed to map the cosmic microwave background is the recent detection of a new component of foreground Galactic emission. The anomalous foreground at similar to 10 - 30 GHz, unexplained by ...

(CEUR-WS, 2017)IMGpedia is a linked dataset that provides a public SPARQL endpoint where users can answer queries that combine the visual similarity of images from Wikimedia Commons and semantic information from existing knowledge-bases. ...

Antarctic ice sheet discharge driven by atmosphere-ocean feedbacks at the Last Glacial Termination (Nature, 2017)Reconstructing the dynamic response of the Antarctic ice sheets to warming during the Last Glacial Termination (LGT; 18,000-11,650 yrs ago) allows us to disentangle ice-climate feedbacks that are key to improving future ...
-
(MDPI, 2021)Eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and carotenoids are needed as human dietary supplements and are essential components in commercial feeds for the production of aquacultured seafood. Microorganisms ...
-
(Elsevier B.V., 2019)Chronic hypobaric hypoxia during fetal and neonatal life induces neonatal pulmonary hypertension. Hypoxia and oxidative stress are driving this condition, which implies an increase generation of reactive oxygen species ...
