  • Crawford B.; Castro C.; Monfroy E. (2014-04-04)
    Our research is focused on developing hybrid solvers for Combinatorial Optimization Problems. We are concerned with the design of hybrid resolution approaches including Constraint Programming and Metaheuristics. We have ...
  • Diaz M.; Venturini E.; Marchetti S.; Arenas G.; Marshall S.H. (2014-04-04)
    Different strategies have been used to overcome the difficulties to produce antimicrobial peptides. Here we used Intein Mediated Purification with an Affinity Chitin-binding Tag (IMPACT-System, New England Biolabs) for the ...
  • Cataldo M.; Mella P.; Minning P.; Saavedra J. (2014-04-04)
    We provide a detailed description for power-law scaling Friedmann-Robertson-Walker cosmological scenarios dominated by two interacting perfect fluid components during the expansion. As a consequence of the mutual interaction ...
  • Campo S.D.; Herrera R.; Pavon D. (2014-04-04)
    It is argued that cosmological models that feature a flow of energy from dark energy to dark matter may solve the coincidence problem of late acceleration (i.e., ''why the energy densities of both components are of the ...
  • Del Campo S.; Herrera R.; Olivares G.; Pavon D. (2014-04-04)
    The coincidence problem of late cosmic acceleration is a serious riddle in connection with our understanding of the evolution of the Universe. In this paper we show that an interaction between the dark energy component ...
  • Avelino A.; Leyva Y.; Urena-Lopez L.A. (2014-04-04)
    We revise the conditions for the physical viability of a cosmological model in which dark matter has bulk viscosity and also interacts with dark energy. We have also included radiation and baryonic matter components; all ...
  • Villenas F.; Soto D.; Palma S. (2014-04-04)
    Zooplankton biomass was compared between the fraction of chitinous and gelatinous organisms from the southern region of Chile between Puerto Montt and Boca del Guafo, in the springs of 2004 and 2005. The biomass values ...
  • Cubillos C.; Gaete S. (2014-04-04)
    The present work continues a longer research in the field of flexible transportation services and the design of an agent system devoted to the planning, scheduling and control of trips under such a domain. In particular, ...

  • Monfroy E.; Crawford B.; Soto R. (2014-04-04)
    The main characteristic of any constraint solver is Constraint propagation. Then it is very important to be able to manage constraint propagation as efficiently as possible, we present a hybrid solver based on a Branch and ...
  • Herrera R.; Olivares M.; Videla N. (2014-04-04)
    An intermediate inflationary universe model in the context of a generalized Chaplygin gas is considered. For the matter we consider two different energy densities; a standard scalar field and a tachyon field, respectively. ...
  • Herrera R.; Videla N. (2014-04-04)
    In this article we study an intermediate inflationary universe models using the Gauss-Bonnet brane. General conditions required for these models to be realizable are derived and discussed. We use recent astronomical ...
  • del Campo S.; Herrera R. (2014-04-04)
    Brane inflationary universe model in the context of intermediate inflation is studied. General conditions for this model to be realizable are discussed. In the high-energy limit we describe in great details the characteristic ...
  • Herrera R.; Olivares M.; Videla N. (2014-04-04)
    Brane and warped Dvali-Gabadadze-Porrati inflationary universe models in the context of intermediate inflation are studied. In both models we consider that the energy density is a standard scalar field and we discuss the ...
  • Estupinan-Serrano M.L. (2014-04-04)
    [No abstract available]
  • Ruddoff D. (2014-04-04)
    As the result of a thesis project that studied the plan of Valparaiso, with the various ways of occupying the blocks, a possibility is presented for intervening a residential building on the base of the Cordillera hill ...
  • Hormazabal S.; Combes V.; Morales C.E.; Correa-Ramirez M.A.; Di Lorenzo E.; Nunez S. (2014-04-04)
    The three-dimensional structure and the origin of mesoscale anticyclonic intrathermocline eddies (ITEs) in the coastal transition zone (CTZ) off central Chile (31-41°S) were analyzed through the combination of data from ...
  • MacChi M.; Kristjanpoller F.; Garetti M.; Arata A.; Fumagalli L. (2014-04-04)
    The throughput analysis is an important issue for the design and operations management of process production lines. The throughput of a line depends on the availability and nominal throughput of its machines. Further on, ...
  • Illanes A. (2014-04-04)
    Many chemical reactions can occur spontaneously; others require to be catalyzed to proceed at a significant rate. Catalysts are molecules that reduce the magnitude of the energy barrier required to be overcame for a substance ...
  • Saghin R.; Vargas E. (2014-04-04)
    We investigate the invariant probability measures for Cherry flows, i. e. flows on the two-torus which have a saddle, a source, and no other fixed points, closed orbits or homoclinic orbits. In the case when the saddle is ...
