(UNIV CHICAGO PRESS, 2007-11-10)We report observations of 6 cm, 3.6 cm, 1.3 cm, and 7 mm radio continuum, conducted with the Very Large Array, toward IRAS 18566+0408, one of the few sources known to harbor H(2)CO6 cm maser emission. Our observations ...
-
(Oxford University Pres, 2017)The H2O Southern Galactic Plane Survey (HOPS) has mapped 100 deg(2) of the Galactic plane for water masers and thermal molecular line emission using the 22 m Mopra telescope. We describe the automated spectral-line fitting ...
-
(Universidad de Chile, 2021)En las últimas décadas, una parte de las investigaciones sobre resultados académicos de los y las estudiantes se ha enfocado en el impacto que tienen las características socioemocionales en el rendimiento educacional y en ...
-
(Universidad de Chile, 2017)Realizar mediciones viento en altura con técnicas tradicionales como globos cautivos y radiosondas es una tarea demandante en tiempo y recursos. Una de las soluciones a esto es la utilización de técnicas remotas como SODAR ...
-
(Universidad de Chile, 2019)La estabilidad mecánica de taludes mineros es una temática de primera relevancia en todas las operaciones mineras a cielo abierto del mundo. Esto debido a que tiene repercusiones directas en la continuidad de la explotación ...
-
(Universidad de Chile, 2019)La modelación de elecciones discretas tiene diversas aplicaciones prácticas relevantes en varias áreas del conocimiento, incluyendo economía, marketing, medio ambiente, salud y transporte. El enfoque de modelación usual ...
-
(Universidad de Chile, 2023)En los últimos años ha habido un crecimiento abrupto en la masividad de la tecnología de realidad virtual, en conjunto con la tendencia de las ultimas décadas de la masificación de los videojuegos. Pese a este rápido ...
-
(Universidad de Chile, 2014)Si bien la interoperabilidad ha sido entendida como la habilidad de dos o más sistemas o componentes para intercambiar y utilizar información, dentro del Estado su interpretación se extiende más allá del concepto puramente ...
-
(2009)We prove that the class of generalized ultrametric matrices (GUM) is the largest class of bipotential matrices stable under Hadamard increasing functions. We also show that any power α ≥ 1, in the sense of Hadamard ...
-
(BLACKWELL, 2008-11)An interesting case of 'halogen-bonding-promoted' crystal structure architecture is presented. The two title compounds, C8H8Br2O2 and C8H8I2O2, have almost indistinguishable molecular structures but very different spatial ...
-
(Elsevier Ltd, 2019)© 2018 Elsevier LtdThe ratio of the halogens F and Cl in apatite is highly sensitive to changes in the composition of an evolving silicate melt or aqueous fluid. For this reason apatite chemistry is widely used as a monitor ...
-
(Universidad de ChilePrograma Cybertesis, 2009)El presente trabajo de título tiene por objetivo estudiar si los cambios de límites de inversión de los fondos de pensiones han afectado la volatilidad del mercado chileno, específicamente sobre los retornos del IPSA. Para ...
-
(Edward Elgar Publishing, 2023)"Taking a comprehensive approach to two central, closely intertwined themes in the field of transport economics, this illuminating Handbook recognises the critical socioeconomic importance of transport pricing and financing. ...
-
(Hindawi Publishing Corporation, 2013)Background. Haptic robots allow the exploitation of known motor learning mechanisms, representing a valuable option for motor treatment after stroke. The aim of this feasibility multicentre study was to test the clinical ...
-
(Cambridge Univ Press, 2015)This article contains numerical and theoretical results on the circular and polygonal hydraulic jumps in the framework of inertial lubrication theory. The free surface and velocity fields are computed along with ...
-
(2015)Context. Planetary companions of a fixed mass induce reflex motions with a larger amplitude around lower-mass stars, which adds to making M dwarfs excellent targets for extra-solar planet searches. The most recent ...
-
(EDP Sciences, 2015)K2 space observations recently found that three super-Earths transit the nearby M dwarf K2-3. The apparent brightness and the small physical radius of their host star rank these planets amongst the most favourable for ...
-
(WILEY-BLACKWELL, 2011-05)P>In the case of small pelagic fish, it seems reasonable to consider harvest functions depending nonlinearly on fishing effort and fish stock. Indeed, empirical evidence about these fish species suggests that marginal catch ...
-
(IOP Publishing Ltd, 2018)We report the discovery of four short-period extrasolar planets transiting moderately bright stars from photometric measurements of the HATSouth network coupled to additional spectroscopic and photometric follow-up ...
-
(UNIV CHICAGO PRESS, 2013-02)HATSouth is the world's first network of automated and homogeneous telescopes that is capable of year-round 24 hr monitoring of positions over an entire hemisphere of the sky. The primary scientific goal of the network is ...
