(EDP SCIENCES S A, 2008-03)Aims. This paper reports molecular observations towards the Bright Eastern Knot (BEK) in the SNR Puppis A, a feature where radio and X-ray studies suggest that the shock front is interacting with a dense molecular ...
-
(Sociedad Medica de Santiago, 2019)Background: Cytogenetic abnormalities observed in the bone marrow of patients with multiple myeloma (MM) are an important prognostic factor for risk stratification. Aim: To investigate karyotype characteristics and frequency ...
-
(Elsevier, 2011)New petrologic, thermobarometric and U-Pb monazite geochronologic information allowed to resolve the metamorphic evolution of a high temperature mid-crustal segment of an ancient subduction-related orogen. The El Portezuelo ...

High- and low-latitude forcings drive Atacama desert rainfall variations over the past 16,000 years (Amer Assoc Advancement Science, 2021)Late Quaternary precipitation dynamics in the central Andes have been linked to both high- and low-latitude atmospheric teleconnections. We use present-day relationships between fecal pellet diameters from ashy chinchilla rats ...
-
(CAMBRIDGE UNIV PRESS, 2006-04)In this article we study the asymptotic dynamics of highly oscillatory solutions for the unbalanced Allen-Cahn equation with a slowly varying coefficient. We describe the underlying structure of these solutions through a ...
-
(Frontiers Media, 2021)The ocean off south-central Chile is subject to seasonal upwelling whose intensity is mainly controlled by the latitudinal migration of the southeast Pacific subtropical anticyclone. During austral spring and summer, the ...
-
(2009-12)We investigate the environment of the nearby (d 40 Mpc) broad-lined Type Ic supernova SN 2009bb. This event was observed to produce a relativistic outflow likely powered by a central ac- creting compact object. While ...

(2003-04)We present a new X-ray–selected high-redshift quasar CXOCY J125304.0 090737 at z = 4.179, discovered by the Cala´n-Yale Deep Extragalactic Research (CYDER) Survey. This quasar is the fifth X-ray– selected high-redshift ...
-
(EDP Sciences, 2015)Context. Transitional disks are circumstellar disks with dust gaps thought to be related in some cases to planet formation. They can shed light on the planet formation process by the analysis of their gas and dust properties. ...

High-resolution spectroscopic search for the thermal emission of the extrasolar planet HD 217107 b (EDP SCIENCES, 2011-05)We analyzed the combined near-infrared spectrum of a star-planet system with thermal emission atmospheric models, based on the composition and physical parameters of the system. The main objective of this work is to obtain ...
-
(Nature, 2022)A two-dimensional material - Mg2B4C2, belonging to the family of the conventional superconductor MgB2, is theoretically predicted to exhibit superconductivity with critical temperature T-c estimated in the 47-48 K range ...
-
(Elsevier Inc., 2019)© 2018 American Society for Reproductive MedicineObjective: To study the reproductive and metabolic differences between daughters of women with polycystic ovary syndrome (PCOSd) and control women (Cd) after menarche. Design: ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-06-01)This paper deals with the asymptotic stability analysis of a discrete dynamical inclusion whose right-hand side is a convex process. We provide necessary and sufficient conditions for weak asymptotic stability, and obtain ...
-
(ELSEVIER SCIENCE BV, 2016)A novel Pt-free Rb/Cu/YCeO2 catalyst was applied to the adsorption of NO under oxidizing conditions. The results show a much greater performance of this catalyst relative to a Pt/Ba/Al2O3 catalyst. The results suggest that ...

-
(Elsevier, 2020)Multifunctional chitosan/magnetite (CS/Fe3O4) and graphene/chitosan/magnetite (Gr/CS/Fe3O4) nanocomposites (NCs) were synthesized using a simple hydrothermal method. The NCs were subsequently evaluated as magnetic ...
-
(Royal Society of Chemistry, 2018)This work describes the design, synthesis and physicochemical properties of the highly emissive nanocomposite [bentonite][Eu{(η5-Cp*)Ru(η6-bzac)}3Phen]0.09[H2O]0.22 based on the Eu(III) complex [Eu{(η5-Cp*)Ru(η6-bzac)}3P ...
-
(Elsevier, 2018)Peridotite xenoliths collected from alkali basalts in the Argentinian Patagonia reveal the existence of an ancient depleted Paleoproterozoic mantle that records a subsequentmultistage metasomatic history.Metasomatismis ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-05)It has become increasingly common worldwide to auction the construction and operation of new highways to the bidder that charges the lowest toll. The resulting highway franchises often entail large increases in the value ...
