(2010-03)We present photometric and spectroscopic observations of SN 2007if, an overluminous (MV = -20.4), red (B -V = 0.16 at B-band maximum), slow-rising (trise = 24 days) type Ia supernova (SN Ia) in a very faint (Mg = -14.10) ...
-
(EDP Sciences, 2016)The metallicity of a supernova progenitor, together with its mass, is one of the main parameters that can rule the progenitor's fate. We present the second study of nearby supernova (SN) host galaxies (0.005 < z < 0.03) ...
-
(2001-03)We report the discovery of a new double-image gravitational lens, resulting from our search for lenses in the southern sky. Radio source PMN J2004[1349 is composed of two compact components separated by 1A.13 in VLA, ...
-
(EDP Sciences, 2015)Aims. We present and analyse late-time observations of the Type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, which were done similar to 300 days after the explosion. We discuss them in the ...
-
(Taylor & Francis, 2019)Necessary and sufficient conditions for qualitative properties of infinite dimensional linear programing problems such as solvability, duality, and complementary slackness conditions are studied in this article. As ...
-
(LONDON MATH SOC, MORGAN HOUSE, 2005-12)Necessary and sufficient conditions are given for linearly recurrent Cantor dynamical systems to have measurable and continuous eigenfunctions. Also an example of a linearly recurrent system with a nontrivial Kronecker ...
-
(American Institute of Mathematical Sciences, 2020)We consider a set of necessary conditions which are efficient heuristics for deciding when a set of Wang tiles cannot tile a group. Piantadosi [19] gave a necessary and sufficient condition for the existence of a valid ...

-
(Frontiers Media, 2021)This is the first pilot study on alternative conceptions and obstacles pertaining to pneumonia in adolescents of different school vulnerability indexes. Countries with low socioeconomic levels are disproportionately affected, ...
-
(Elsevier, 2022)In a Stackelberg network pricing game a leader sets prices for a given subset of edges so as to maximize profit, after which one or multiple followers choose a shortest path. Our main result shows that the profit when ...

(AMER METEOROLOGICAL SOC, 1988-02)
-
(Wiley Periodicals, 2014)Reforms designed to improve the quality of teaching by reforming personnel practices, such as pay for performance arrangements, usually run into opposition from well-organized teacher unions that can either block reform in ...
-
(Springer, 2020)Given a simple graph G, a set C subset of V(G)\documentclass[12pt] is a neighborhood cover set if every edge and vertex of G belongs to some G[v] with v is an element of C\documentclass[12pt] denotes the subgraph of G ...
-
(Universidad de Barcelona, 2019)It is known that the high-rise, private real estate exploitation in pericentral Santiago, Chile creates exclusionary social stratification. However, newer questions arises about the actions, motivations and expectations ...
-
(2007)Recent studies show that the western margin of the Andean plateau was uplifted during Neogene time in the form of a proto-Western Cordillera through a system of high angle reverse faults. In this study, we use XRD and ...
-
(Elsevier, 2015)The Miocene Manantiales Foreland Basin is defined as a thick succession of sedimentary rocks belonging to the Chinches Formation in the Frontal Cordillera between 32 degrees S and 32 degrees 30 degrees S, located over the ...
-
(Elsevier B.V., 2008-12)Giant landslides, which usually have volumes up to several tens of km3, tend to be related to mountainous reliefs such as fault scarps or thrust fronts. The western flank of the Precordillera in southern Peru and ...
-
(PERGAMON-ELSEVIER SCIENCE, 2005-05)The stratigraphy, sedimentology, and paleontology of the Coquimbo Formation in a coastal section approximately 100km north of La Serena was Studied to establish relative low-order sea-level changes during the Neogene. ...
-
(Elsevier, 2015)This study examines the neotectonic deformation and development of the Tromen massif, a Quaternary retroarc volcanic field located in the western section of the Malargue fold and thrust belt in the Southern Central Andes. ...
-
(Brill Academic Publishers, 2006)The average transient time, damage spreading and qualitative effects are determined for the NER automata parallel dynamics defined on random graphs. It was obtained that the NER automata converge with linear rate to fixed ...
