(EDP Sciences, 2020)Context. RX J1604.3-2130A is a young, dipper-type, variable star in the Upper Scorpius association, suspected to have an inclined inner disk, with respect to its face-on outer disk. Aims. We aim to study the eclipses to ...
-
(M E SHARPE INC, 2005-07)This paper focuses on return spillovers in stock markets at different time scales using wavelet analysis. We look at eight stock indices that comprise the G7 countries, emerging Asia, Western Europe, Eastern Europe and the ...
-
(Elsevier, 2017)Three seismic sequences of several thousand earthquakes each are analyzed by means of a tunable information recognizer known as wlzip. These sequences are different both in the geographical coverage and the time span, ...
-
(Earthquake Engineering Research Institute, 2018)This paper presents the identification of the instantaneous modal properties and the experimental response of a full-scale, five-story base-isolated RC building tested on a shake table. A suite of earthquake motions of ...
-
(Springer-Verlag, 2014)New geochronological data from the Los Bronces cluster of the Río Blanco-Los Bronces mega-porphyry Cu-Mo district establish a wide range of magmatism, hydrothermal alteration, and mineralization ages, both in terms of ...
-
(Frontiers Media S.A., 2019)Active sensing refers to the concept of animals perceiving their environment while involving self-initiated motor acts. As a consequence of these motor acts, this activity produces direct and timely changes in the sensory ...
-
(ELSEVIER, 2006-11-01)Very dense bidimensional systems of inelastic hard disks excited from the base are studied by means of Newtonian event driven molecular dynamics. A stationary regime is reached where almost perfect crystallographic order ...

(E Schweizerbartsche Verlagsbuchhandlung, 2017)Humite minerals, including Ti-rich, hydroxyl-dominant chondrodite and clinohumite, occur in Paleozoic antigorite serpentinite in the La Cabana area, in the Chilean Coastal Cordillera (similar to 38 degrees 30'S- 73 degrees ...
-
(Elsevier, 2004)We evaporated polycrystalline copper thin films of thickness between 10 and 100nm on silicon substrates with their native oxide under ultra-high-vacuum conditions. Some of them were exposed to air for a period ranging ...
-
(Frontiers Media S.A., 2019)Enteroaggregative Escherichia coli (EAEC) infections are one of the most frequent causes of persistent diarrhea in children, immunocompromised patients and travelers worldwide. The most prominent colonization factors of ...
-
(Nature Publishing Group, 2019)Oligodendrocyte precursor cells (OPCs) differentiate during postnatal development into myelin-forming oligodendrocytes, in a process distinguished by substantial changes in morphology and the onset of myelin gene expression. ...

To index or not to index:|bTime-space trade-offs in search engines with positional ranking functions (Universidad de Chile, 2014)Web search has become an important part of day-to-day life. Web search engines are important tools that give access to the information stored in the web. The success of a web search engine mostly depends on its efficiency ...

(Universidad de Chile, 2015)El proyecto modernizador aplicado en Chile durante las últimas décadas ha consolidado una estructura productiva preponderantemente rentista, dependiente de los ciclos del precio de las materias primas y de mercados altamente ...
-
(Springer Berlin, 2008-10)We consider the Allen-Cahn equation "2 u+(1−u2)u = 0 in a bounded, smooth domain in R2, under zero Neumann boundary conditions, where " > 0 is a small parameter. Let 0 be a segment contained in , connecting ...
-
(2010)We construct a new class of positive solutions for the classical elliptic problem ¢u ¡ u + up = 0; p > 2; in R2: We establish a deep relation between them and the following Toda system c2f00 j = efj¡1¡fj ¡ efj¡fj+1 in ...
