(American Chemical S, 2013)The stability and reactivity of planar starlike C6Li6 and its hydrogen-adsorbed analogue were analyzed using density functional theory and ab initio molecular dynamics calculations. The ability of the C6Li6 system to ...
-
(IOP Publishing, 2016)A very general cosmological consideration suggests that, along with galactic dark matter halos, much smaller dark matter structures may exist. These structures are usually called ‘clumps’, and their mass extends to 10−6M⊙ ...
-
(Elsevier Ltd, 2018)State-owned enterprises may be strategic for many countries. For political or practical reasons some of these enterprises may remain wholly state-owned (WSOE), like PEMEX in Mexico or CODELCO in Chile. For this group, the ...
-
(2010)In this paper we present radiative-convective simulations to test the idea that tropical cirrus clouds, acting as a negative feedback on climate, can provide a solution to the faint young Sun paradox. We find that global ...
-
(IOP, 2022)Constraints on the cosmological concordance model parameters from observables at different redshifts are usually obtained using the locally measured value of the gravitational constant G(N). Here we relax this assumption, ...
-
(Elsevier, 2014)We examine whether the dynamics of the implied volatility surface of individual equity options contains exploitable predictability patterns. Predictability in implied volatilities is expected due to the learning behavior ...
-
(Oxford University Press, 2018)In large optical surveys at high redshifts (z > 2), the C IV λ1549 broad emission line is the most practical alternative to estimate the mass (MBH) of active supermassive black holes. However, mass determinations obtained ...
-
(Taylor and Francis Ltd, 2019)Background: Robinson Crusoe Island is a geographically and socially isolated settlement located over 600 km west of the Port of Valparíso, Chile. An unusually high incidence (30%) of the Chilean equivalent of developmental ...
-
(ASSOC COMPUTING MACHINERY, 2017)Existential blank nodes greatly complicate a number of fundamental operations on RDF graphs. In particular, the problems of determining if two RDF graphs have the same structure modulo blank node labels (i.e. if they are ...
-
(Springer Verlag, 2018)Caching in the context of expressive query languages such as SPARQL is complicated by the difficulty of detecting equivalent queries: deciding if two conjunctive queries are equivalent is NP-complete, where adding further ...
-
(MDPI, 2020)This paper addresses the planning and deployment of wireless heterogeneous networks (WHNs) for smart metering, based on a cross-layer solution. We combine the constraints of the network layer that considers routing and ...
-
(Palgrave Macmillan Ltd., 2019)Using a panel data set for international corporate bonds and capital account restrictions in advanced and emerging economies, we show that restrictions on capital inflows produce a substantial and economically meaningful ...
-
(Wiley-Blackwell, 2019)Background: Encapsulation of Porphyromonas gingivalis has been demonstrated as responsible of several host immunological changes, which have been associated with the pathogenesis of periodontitis. Using a murine model of ...
-
(Elsevier, 2020)One of the current challenges in structural health monitoring (SHM) is to take the most advantage of large amounts of data to deliver accurate damage measurements and predictions. Deep Learning methods tackle these ...
-
(Nature, 2013)Carbon monoxide (CO) is the primary tracer for interstellar clouds where stars form, but it has never been detected in galaxies in which the oxygen abundance relative to hydrogen is less than 20 per cent of that of the ...
-
(EDP Sciences, 2013)Aims. We analyze the carbon monoxide emission around the starWR 16 aiming to study the physical characteristics of the molecular gas linked to the star and to achieve a better understanding of the interaction between ...
-
(SPRINGER, 2011-03)The influence of external colored noise on the carbon monoxide oxidation on Iridium(111) surfaces is examined. The noise is introduced in the reaction by randomly varying the composition of the gas flow that keeps the ...
-
(Sociedad Chilena de Quimica, 2019)A multi-walled carbon nanotube (MWCNT)-ionic liquid (IL) film-modified glassy carbon electrode (GCE) was constructed for the determination of pseudoephedrine (PE) and chlorpheniramine (CP) by differential pulse voltammetry ...
-
(1996-12)We present RI and JHK photometry for 888 and 204 carbon (C) stars, respectively, of the 1035 C stars found by Blanco and his collaborators in 52 fields of the Large Magellanic Cloud (LMC). The results of our analysis of ...
