  • An efficient algorithm for approximated self-similarity joins in metric spaces 

    Ferrada Aliaga, Sebastián; Bustos Cárdenas, Benjamín; Reyes, Nora (Elsevier, 2020)
    Similarity join is a key operation in metric databases. It retrieves all pairs of elements that are similar. Solving such a problem usually requires comparing every pair of objects of the datasets, even when indexing and ...

  • Colouring exact distance graphs of chordal graphs 

    Quiroz Brito, Daniel (Elsevier, 2020)
    For a graph G = (V, E) and positive integer p, the exact distance-p graph G([hp]) is the graph with vertex set V and with an edge between vertices x and y if and only if x and y have distance p. Recently, there has been ...

  • A tip for landscape riders: multi-field inflation can fulfill the swampland distance conjecture 

    Bravo, Rafael; Palma, Gonzalo A.; Riquelme, Simón (IOP, 2020)
    We study how both the swampland distance conjecture and the Lyth bound affect the parameter space of multi-field models of inflation. A generic feature of multi-field inflation is that the geodesic distance [Delta phi](G) ...

    We report the detection of a transiting super-Earth-sized planet (R = 1.39 +/- 0.09 R-circle plus) in a 1.4-day orbit around L 168-9 (TOI-134), a bright M1V dwarf (V = 11, K = 7.1) located at 25.15 +/- 0.02 pc. The host ...
  • When gas dynamics decouples from galactic rotation: characterizing ism circulation in disk galaxies 

    Utreras, José; Blanc, Guillermo; Escala Astorquiza, Andrés; Meidt, Sharon; Emsellem, Eric; Bigiel, Frank; Glover, Simon C.O.; Henshaw, Jonathan; Hygate, Alex; Diederik Kruijssen, J. M.; Rosolowsky, Erik; Schinnerer, Eva; Schruba, Andreas (IOP Publishing, 2020)
    In galactic disks, galactic rotation sets the bulk motion of gas, and its energy and momentum can be transferred toward small scales. Additionally, in the interstellar medium, random and noncircular motions arise from ...
  • Two-dimensional optical chimera states in an array of coupled waveguide resonators 

    Clerc Gavilán, Marcel; Coulibaly, S.; Ferré, M. A.; Tlidi, M. (American Institute of Physics, 2020)
