(EDP Sciences, 2018-05-15)Magnetar power is believed to be at the origin of numerous super-luminous supernovae (SNe) of Type Ic, arising from compact, hydrogen-deficient, Wolf-Rayet type stars. Here, we investigate the properties that magnetar power ...

(The American Astronomical Society, 2018-05-20)We present detailed ultraviolet, optical, and near-infrared light curves of the Type Ia supernova (SN) 2012fr, which exploded in the Fornax cluster member NGC 1365. These precise high-cadence light curves provide a dense ...
-
(Elsevier, 2018-05)We provide a solution to the adaptive control problem of an unknown linear system of a given derivation order, using a reference model or desired poles defined in a possibly different derivation order and employing continuous ...
-
(Elsevier, 2018-06)Ferritin is a globular protein that consists of 24 subunits forming a hollow nanocage structure that naturally stores iron oxyhydroxides. Elimination of iron atoms to obtain the empty protein called apoferntin is the first ...
-
(Wiley, 2018-04)The far eastern tropical Pacific experienced a rapid, marked warming in early 2017, causing torrential rains along the west coast of South America with a significant societal toll in Peru and Ecuador. This strong coastal ...
-
(Elsevier, 2018-07)Besides temperature, mineralogy, residence time and dilution are crucial for assessing water-rock interaction intensity. The geothermal system at the Villarrica-Quetrupillan-Lanin volcanic chain, Southern Chile, is located ...
-
(Wiley, 2018-06)This paper presents an approach to generalize the concept of isogeometric analysis by allowing different spaces for the parameterization of the computational domain and for the approximation of the solution field. The ...
-
(IEEE, 2018-05)Urban planning and intelligent transportation management are facing key challenges in today's ever more urbanized world. Providing the right tools to city planners is crucial to cope with these challenges. Data collected ...
-
(Springer, 2018-06)In this paper we study qualitative properties of global minimizers of the Ginzburg-Landau energy which describes light-matter interaction in the theory of nematic liquid crystals near the Freedericksz transition. This model ...
-
(Inst. Mathematical Statistics, 2018-04)Random hyperbolic graphs have been suggested as a promising model of social networks. A few of their fundamental parameters have been studied. However, none of them concerns their spectra. We consider the random hyperbolic ...
-
(Springer, 2018-06)Coherently, embedded metal nanostructures (endotaxial) are known to have potential applications concerning the areas of plasmonics, optoelectronics and thermoelectronics. Incorporating appropriate concentrations of metal ...
-
(EDP Sciences, 2018-05-30)Aims. We aim to reveal the morphology, chemical composition, kinematics, and to establish the main processes prevalent in the gas at the footpoints of the giant molecular loops (GMLs) in the Galactic center region. ...
-
(Universidad de Chile, 2018)La evaluación de riesgos en los proyectos mineros es una problemática recurrente debido a la incertidumbre presente en las distintas etapas de evaluación, esto hace que sea de gran interés el poder anticiparse a situaciones ...
-
(American Geophysical Union, 2018-04-27)A record-setting temperature of 17.5 degrees C occurred on 24 March 2015 at the Esperanza station located near the northern tip of the Antarctic Peninsula (AP). We studied the event using surface station data, satellite ...
-
(Universidad de Chile, 2018)El valor público, como fin último de la gerencia social, resulta indiscutible del punto de vista del desarrollo de la sociedad, en consecuencia, generar una medición del mismo implicaría mejorar la orientación y gestión ...
-
(Oxford University Press, 2018)We present a sample of 34 weak metal line absorbers at z < 0.3 selected by the simultaneous > 3 sigma detections of the Si II lambda 1260 and CII lambda 1334 absorption lines, with W-r (Si II) < 0.2 angstrom and W-r (C II) ...

Constraints on core-collapse supernova progenitors from explosion site integral field spectroscopy (EDP Sciences, 2018-05-28)Context. Observationally, supernovae (SNe) are divided into subclasses according to their distinct characteristics. This diversity naturally reflects the diversity in the progenitor stars. It is not entirely clear, however, ...
-
(Springer, 2018-05)We propose a new iterative algorithm for the numerical approximation of the solutions to convex optimization problems and constrained variational inequalities, especially when the functions and operators involved have a ...
-
(Elsevier, 2018-06-15)Structural and mechanical Characterizations of La1.8M0.2NiO4+delta (M: Sr and Ba) prepared by low frequency ultrasound assisted synthesis technique and sintered at different temperatures were studied. HRTEM and XRD analyses ...
