(EDP Sciences, 2017)We report the discovery of a substellar companion around the giant star HIP 67537. Based on precision radial velocity measurements from CHIRON and FEROS high-resolution spectroscopic data, we derived the following orbital ...
-
(EDP Sciences, 2017)We present the first optical observation of the microquasar SS 433 at sub-milliarcsecond (mas) scale obtained with the GRAVITY instrument on the Very Large Telescope interferometer (VLTI). The 3.5-h exposure reveals a rich ...
-
(Wiley, 2017)BACKGROUND: Gene therapy is a potent alternative for long-lasting inhibition of alcohol consumption. This study compares the purification of a recombinant adenoviral vector serotype 5 (rAdV5) for use in gene therapy against ...
-
(IOP Publishing Ltd, 2017)We present a spectroscopic survey of high-redshift, luminous galaxies over four square degrees on the sky, aiming to build a large and homogeneous sample of Ly alpha emitters (LAEs) at z approximate to 5.7 and 6.5, and ...
-
(EDP Sciences, 2017)Aims. We present a spectroscopic study of the dynamics of the ionized and neutral gas throughout the Lagoon nebula (M 8), using VLT-FLAMES data from the Gaia-ESO Survey. The new data permit exploration of the physical ...
-
(IOP Publishing Ltd, 2017)During the Space Telescope and Optical Reverberation Mapping Project observations of NGC 5548, the continuum and emission-line variability became decorrelated during the second half of the six-month-long observing campaign. ...
-
(Association for Computing Machinery, 2017)This paper reports on recent advances in semantic query optimization. We focus on the core class of conjunctive queries (CQs). Since CQ evaluation is NP-complete, a long line of research has concentrated on identifying ...
-
Low dimensional embedding of climate data for radio astronomical site testing in the Colombian Andes (IOP Publishing Ltd, 2017)We set out to evaluate the potential of the Colombian Andes for millimeter-wave astronomical observations. Previous studies for astronomical site testing in this region have suggested that nighttime humidity and cloud cover ...
-
(Universidad de Chile, 2017)Esta investigación tiene como propósito central generar una propuesta para un alineamiento estratégico en la función de orientación a establecimientos educacionales de la Agencia de Calidad de la Educación, a partir de un ...
-
(Universidad de Chile, 2017)En el presente estudio se propone y evalúa el uso de una tecnología hiperespectral en el rango espectral SWIR como método cualitativo de detección mineral para su uso en la toma de decisiones durante el procesamiento ...
-
(Universidad de Chile, 2017)En Chile se han realizado investigaciones que abordan las condiciones de habitabilidad, reinserción y el impacto de las políticas penitenciarias desde la arista de los Derechos Humanos. En los últimos años se han desarrollado ...
-
(Universidad de Chile, 2017)El presente trabajo mide el impacto de los factores que han incidido en la caída de costo marginal del 33% en el Sistema Interconectado Central (SIC) en el 2016, un fenómeno que no se veía en casi 10 años, desde el corte ...
-
(Universidad de Chile, 2017)El trabajo de tesis se realizó en Correos de Chile, empresa con más de 280 años de antigüedad y líder en el mercado postal a nivel nacional, con una participación de mercado cercana al 60% en cartas y de un 30% en paquetería. ...
-
(Elsevier, 2017)The relationship between train occupancy, comfort and perceived security is analysed, using data from a survey and stated choice (SC) study of users of Santiago's Metro (subway) system. Mode choice models where crowding ...
-
(Wiley, 2017)This work presents a detailed investigation of a parameter estimation approach on the basis of the reduced-order unscented Kalman filter (ROUKF) in the context of 1-dimensional blood flow models. In particular, the main ...
-
(Elsevier, 2017)Ultrasound has long been used as a non-destructive tool to test for the brittle fracture of materials. Could it be used as a similar tool to test for ductile failure? As a first step towards answering this question, we ...
-
(EDP Sciences, 2017)Aims. Shadows in transitional disks are generally interpreted as signs of a misaligned inner disk. This disk is usually beyond the reach of current day high contrast imaging facilities. However, the location and morphology ...
-
(EDP Sciences, 2017)As part of the accretion discs in H alpha with OmegaCAM (ADHOC) survey, we imaged a region of 12x8 square degrees around the Orion Nebula Cluster in r, i and H alpha. Thanks to the high-quality photometry obtained, we ...
-
(Public Library Science, 2017)Category Theory, a branch of mathematics, has shown promise as a modeling framework for higher-level cognition. We introduce an algebraic model for analogy that uses the language of category theory to explore analogy-related ...
-
(SIAM Publications, 2017)In this paper we present a new method to solve differential inclusions in Hilbert spaces. This method is a Galerkin-like method where we approach the original problem by projecting the state into a n-dimensional Hilbert ...
