    • Lund Plantat, Fernando (Amer Phisical Soc, 2015)
      The normal modes of a continuum solid endowed with a random distribution of line defects that behave like elastic strings are described. These strings interact with elastic waves in the bulk, generating wave dispersion and ...
    • Cáceres, Gabriel; González Cataldo, Felipe; Gutiérrez, Gonzalo (Institute of Physics Publishing, 2018)
      Using classical molecular dynamics, we study the time evolution of out-of-plane standing waves on a square and circular single-layer graphene membrane. We explore the first six normal modes, obtaining the oscillation ...

(Nature, 2021)
      Two serendipitously detected dust-obscured galaxies are reported at z = 6.7 and 7.4, with estimates that such galaxies provide an additional 10-25% contribution to the total star formation rate density at z > 6. Over ...

    • Travieso Torres, Juan Carlos; Duarte Mermoud, Manuel Armando (MDPI, 2022)
      Recently, a novel high-starting torque scalar control scheme (HST-SCS) for induction motor(s) (IM) emerged. It expands the scalar control application field beyond centrifugal pumps, blowers, and fans, moving, for instance, ...
    • Carrera Galleguillos, Felipe Bersalo (Universidad de Chile, 2014)
      En este trabajo son estudiados los problemas de incentivos que enfrentan líderes dentro de una comunidad y sus efectos sobre la cooperación que se puede sostener en equilibrio. Es considerado un modelo de juego repetido ...

      This paper reports on the photocatalytic activity showed by nanocomposites of TiO2 with low density polyethylene (LDPE) and high density polyethylene (HDPE) (10, 20 wt%) for the degradation of methyl orange in aqueous ...
    • Carretier, Sebastien; Regard, Vincent; Vassallo, Riccardo; Martinod, Joseph; Christophoul, Frederic; Gayer, Eric; Audin, Laurence; Lagane, Christelle (Wiley-Blackwell, 2015)
      Millennial catchment-mean erosion rates derived from terrestrial cosmogenic nuclides are generally based on the assumption that the lithologies of the parent rock each contain the same proportion of quartz. This is not ...
    • Espejo Arenas, Elio Eduardo; Stevens, Angela; Velázquez, Juan J.L. (2009)
    • Bustamante Plaza, Roger; Rajagopal, K. R. (Oxford University Press, 2014)
      The class of elastic bodies, that is bodies incapable of dissipation in whatever motion that they undergo, has been significantly enlarged recently (see Rajagopal 2003, On implicit constitutive theories. Appl. Math., 48, ...
    • Gambaudo, Jean Marc (CAMBRIDGE UNIV PRESS, 2006-02)
      Consider a tiling T of the two-dimensional Euclidean space made with copies up to translation of a finite number of polygons meeting each other full edge to full edge. In this paper, we prove that, associated with T, there ...
    • Lang, Richard (Springer, 2016)
      It is shown that Halin graphs are -edge-choosable and that graphs of tree-width 3 are -edge-choosable and -total-colourable.
