(Springer, 2014)In this paper, we address the evaluation of algorithms for partial shape retrieval using a large-scale simulated benchmark of partial views which are used as queries. Since the scanning of real objects is a time-consuming ...
-
(2016)We present benchmark values for the electronic chemical potential and chemical hardness from reference data for ionization potentials and electron affinities. In cases where the energies needed to compute these quantities ...
-
(Nature, 2020)The explosion of network science has permitted an understanding of how the structure of social networks affects the dynamics of social contagion. In community-based interventions with spill-over effects, identifying ...
-
(Royal Soc Chemistry, 2018)The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS2), and imogolite. For graphene we obtained 3.43 eV angstrom(2) per atom for the bending ...

(Universidad de Chile, 2003)Esta investigación tiene el propósito de estimar beneficios monetarios y recreativo ai interior de la Reserva Nacional Lago Peñuelas, unidad perteneciente al Sistema Nacional de Áreas Silvestres Protegidas del Estado ...
-
(2010)1. A key aspect of the ecology and evolution of adaptive prey responses to predator risk is the timing by which the former develop a defensive trait in response to inducing signals released by the latter. This property, ...
-
(Springer, 2019)We define and study coherent states, a Berezin-Toeplitz quantization and covariant symbols on the product Xi := G x g(#) between a connected simply connected nilpotent Lie group and the dual of its Lie algebra. The starting ...
-
beta 1-subunit-induced structural rearrangements of the Ca2+- and voltage-activated K+ (BK) channel (Natl Acad Sciences, 2016)Large-conductance Ca2+- and voltage-activated K+ (BK) channels are involved in a large variety of physiological processes. Regulatory beta-subunits are one of the mechanisms responsible for creating BK channel diversity ...
-
(COMPANY OF BIOLOGISTS LTD, 2006-10-30)A number of psychiatric and neurodegenerative disorders, such as Alzheimer’s disease, are characterized by abnormalities in the neuronal cytoskeleton. Here, we find that the enhancement in actin polymerization induced ...
-
(2007)A theoretical study of the beta-scission reactions for some thioimidoyl radicals (R-1-N=C-center dot-S-R-2) using a recently introduced homofugality index, nu(center dot) is presented. This index, that was defined as a ...
-
(ELSEVIER GMBH, 2010-08-28)The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating that animals adjust their digestive attributes in order to maximize overall energy return. Using an intraspecific ...
-
(Ecological Society of Australia, 2007)In this work we report on the seasonal trends of abundances in terms of temperature exposure for four coexisting cladoceran species (Daphnia ambigua (Daphniidae), Ceriodaphnia dubia (Daphniidae), Diaphanosoma chilense ...
-
(Sociedad de Biologia de Chile, 2009)In this essay I point out to two processes that can potentially complement the classical view of evolution by natural selection as outlined by Darwin, which captures only part of the processes driving adaptive evolution. ...
-
(2016)Habitat structure determines species occurrence and behavior. However, human activities are altering natural habitat structure, potentially hampering native species due to the loss of nesting cavities, shelter or movement ...
-
(WILEY-V C H VERLAG GMBH, 2007-03)The definition of life has excited little interest among molecular biologists during the past half-century, and the enormous development in biology during that time has been largely based on an analytical approach in ...
-
(John Wiley, 2015)1. The effects of the present biodiversity crisis have been largely focused on the loss of species. However, a missed component of biodiversity loss that often accompanies or even precedes species disappearance is the ...
-
(Plos One, 2013)CNBP is a nucleic acid chaperone implicated in vertebrate craniofacial development, as well as in myotonic dystrophy type 2 (DM2) and sporadic inclusion body myositis (sIBM) human muscle diseases. CNBP is highly conserved ...
-
(Universidad de Chile, 2018)Diversas actividades industriales generan como subproducto la liberación de metales pesados, que, al no ser degradables, se acumulan en el ambiente, incorporándose a las tramas tróficas y bioacumulándose, generando efectos ...
-
(SPRINGER, 2008-12)The diet of jumbo squid (Dosidicus gigas) off southern-central Chile is described to examine potential biases in the determination of their main prey. Specimens were collected from catches using different fishing gear ...
-
(FEBS, 2014)In some archaea, the phosphorylation of glucose and fructose 6-phosphate (fructose 6P) is carried out by enzymes that are specific for either substrate and that use ADP as phosphoryl donor. In the hyperthermophilic ...
