(Elsevier, 2017)In this paper we present an overview of the process of mapping and field surveying of an area of ancient fields and irrigation canals around the pre-Hispanic sites of Topaín, Paniri and Turi, in the Andean highlands of ...

Ground-based detection of calcium and possibly scandium and hydrogen in the atmosphere of HD209458b (EDP Sciences, 2013)Context. Since the first exoplanetary atmosphere detection using the Hubble Space Telescope, characterization of exoplanet atmospheres from the ground have been playing an increasingly important role in the analysis of ...
-
(Oxford University Press, 2018-07)We present high cadence detections of two superflares from a bright G8 star (V = 11.56) with the Next Generation Transit Survey (NGTS). We improve upon previous superflare detections by resolving the flare rise and peak, ...
-
(EDP, 2014)Context. GJ 1214 b is one of the few known transiting super-Earth-sized exoplanets with a measured mass and radius. It orbits an M-dwarf, only 14.55 pc away, making it a favorable candidate for follow-up studies. However, ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005)The list of Ground-Level Enhancements (GLEs) occurring during the on-going solar cycle (no. 23) is used to show that they are absent during a time interval of the maximum phase in which a relative reduction in the sunspot ...
-
(Springer, 2016-11)In order to identify the origin of the main processes that affect the composition of groundwater in a karstic aquifer, a hydrogeochemical and isotopic study was carried out of water from numerous observation wells located ...
-
(ASCE-AMER SOC CIVIL ENGINEERS, 2008-04)This work presents a novel approach for solving groundwater management problems with reduced computational effort. We replace a groundwater flow model governed by a partial differential equation with a simple model governed ...
-
(Elsevier, 2020)In Central Chile, the increment of withdrawals together with drought conditions has exposed the poor understanding of the regional hydrogeological system. In this study, we addressed theWestern Andean Front hydrogeology ...
-
Groundwater resources of the Western Andean Front: insights from the Aconcagua Basin, Central Chile (Universidad de Chile, 2020)The misunderstanding of hydrogeological processes together with the oversimplification of aquifer conceptual models result in numerous inaccuracies in the management of groundwater resources. Despite that Chile is a ...
-
(Universidad Autonoma de Madrid, 2007)Consider a finite group G acting on a Riemann surface S, and the associated branched Galois cover πG : S → Y = S/G. We introduce the concept of geometric signature for the action of G, and we show that it captures much ...
-
(Routledge, 2018)This study considers the firm’s affiliation with business groups and the ownership structure as determinants of leverage decisions in Chilean firms. The major findings show that group-affiliated firms take advantage of ...
-
(Springer, 2015)We describe the action of the full automorphisms group on the Fermat curve of degree N. For N prime, we obtain the group algebra decomposition of the corresponding Jacobian variety.
-
(Institute of Electrical and Electronics Engineers Inc., 2019)© 2000-2011 IEEE.The initiatives of cycling infrastructure enhancements around the world reveal a consistent interest in promoting cycling to transition toward sustainable lifestyles and safe multi-modal commuting. ...
-
(Wiley-Blackwell, 2016)Network information system security has become a global issue since it is related to the economic development and national security. Information system security assessment plays an important role in the development of ...
-
(ELSEVIER, 2006-05-10)We propose and test an empirical nucleofugality index to rank the leaving group ability of a series of molecular fragments present in nucleophilic substitution reactions of carbonyl and thiocarbonyl derivatives. The ...
-
(Amer Acad Pediatrics, 2020)OBJECTIVES: Poor early childhood development in low- and middle-income countries is a major public health problem. Efficacy trials have shown the potential of early childhood development interventions but scaling up is ...
-
(SPRINGER-VERLAG BERLIN, 2004)The concept of context can be advantageously applied to the Computer-Supported Cooperative Work field. The term awareness has traditionally been used in this area without explicit association to context. This paper attempts ...

-
(Elsevier, 2015)Network motifs are local structural patterns and elementary functional units of complex networks in real world, which can have significant impacts on the global behavior of these systems. Many models are able to reproduce ...
-
(Springer, 2022)Purpose The research on adolescents who have grown up around intimate partner violence (IPV) between their parents or caregivers has mostly focused on adolescent’s victimization experiences and the negative impact of this ...
