(WILEY-BLACKWELL, 2012-02)There are two independent molecules, A and B, in the asymmetric unit of the title compound, C19H20N4, in each of which the N=N double bond has an E conformation. The dihedral angles between the pyrazole ring and the p-tolyl ...
-
(WILEY-BLACKWELL PUBLISHING, 2008-09)The molecular conformation of the title compound, C18H18O5, is stabilized by a strong intramolecular hydrogen bond between the hydroxyl and carbonyl groups. The C = C double bond displays an E configuration while the ...

(Elsevier Ltd, 2019)The history and dynamics of deciduous Nothofagus forests along the eastern slopes of the central Patagonian Andes (44°-49°S) remain insufficiently studied and understood, particularly at timescales ranging from centuries ...
-
(BMJ Publishing Group, 2016-12)Objective Antithrombotic agents increase risks of intracerebral haemorrhage (ICH) and associated adverse outcomes. We determined differential effects of early blood pressure (BP) lowering in patients with/without ...
-
(Universidad de Chile, 2019)Extreme waves generated in the ocean are of high importance because various maritime structures in the world, including ships, are confronted to this type of wave events, both in deep waters and in coastal areas. Some ...
-
(Universidad de Chile, 2013)El presente trabajo explora y analiza el uso de herramientas de procesamiento de señales que son comunes en áreas de Ingeniería Eléctrica y Pronóstico y Gestión de Salud en el análisis de series de tiempo financieras. ...
-
(Elsevier, 2016-07)This work presents a novel online early detector of high-volatility clusters based on uGARCH models (a variation of the GARCH model), risk-sensitive particle-filtering-based estimators, and hypothesis testing procedures. ...
-
(Elsevier, 2014)One of the major geological units of the Main Andean Range (Frontal Cordillera) of north–central Chile is a group of composite and heterochronous late Paleozoic–early Mesozoic batholiths that extends for 500 km roughly ...
-
(EDP Sciences S A, 2018)Aims. The early evolutionary stage of brown dwarfs (BDs) is not very well characterized, especially during the embedded phase. Our goal is to gain insight into the dominant formation mechanism of very low-mass objects and ...
-
(Elsevier B.V., 2019)Moderate reduction of dietary protein (from 25% to 8% casein) in pregnant rats, calorically compensated by carbohydrates, gives rise to ‘hidden prenatal malnutrition’ (HPM) in the offspring since it does not alter body and ...
-
(Blackwell Publishing, 2019)© 2018 John Wiley & Sons Australia, LtdAim: Early detection and intervention (EDI) is a main challenge in psychosis research. The Chilean schizophrenia (SZ) national program has universal support and treatment by law for ...
-
(Royal Astronomical Society, 2016-07)An understanding of the mass build-up in galaxies over time necessitates tracing the evolution of cold gas (molecular and atomic) in galaxies. To that end, we have conducted a pilot study called CO Observations with the ...
-
THE EARLY STAGES OF STAR FORMATION IN INFRARED DARK CLOUDS: CHARACTERIZING THE CORE DUST PROPERTIES (The American Astronomical Society, 2010-05-20)Identified as extinction features against the bright Galactic mid-infrared background, infrared dark clouds (IRDCs) are thought to harbor the very earliest stages of star and cluster formation. In order to better characterize ...
-
(ESO, 2015)Context. Type Ib/c supernovae (SNe Ib/c) have been investigated in several single-object studies; however, there is still a paucity of works concerning larger, homogeneous samples of these hydrogen-poor transients, in ...
-
(Springer, 2016)We review the development of earthquake dynamics taken from the point of view of the origin of seismic radiation instead of the detailed study of rupture propagation on complex surfaces. Many features of seismic radiation ...
