      The closet exoplanets to the Sun provide opportunities for detailed characterization of planets outside the Solar System. We report the discovery, using radial velocity measurements, of a compact multiplanet system of ...
    • Vallejos Massa, Javier; Díaz, L. (Springer, 2020)
      Determining stability, quantifying planned dilution, and estimating the potential dilution associated with hangingwall overbreak are critical in the process of stope design in sublevel open stoping mines. To satisfy these ...
    • Cavada Guillén, Juan; Cortés Carrillo, Cristián; Rey, Pablo A. (Taylor & Francis, 2020)

      Available charging information exchanges between mobile electric vehicles (EVs) and charging stations are significantly critical in spatio-temporal coordinated charging services introduced by smart girds. In this paper, ...
    • Massone Sánchez, Leonardo; Correa, Agustín (Elsevier, 2020)
      Columns that are at the intersection of frames in two different directions are subjected to biaxial shear when lateral loads are simultaneously applied in two directions. Using the resultant shear and evaluating one-way ...

      Context. We report new HI observations of four z similar to 0.05 VALES galaxies undertaken during the commissioning phase of the Five-hundred-meter Aperture Spherical Radio Telescope (FAST).Aims. FAST is the largest ...
    • Rodríguez Bustamante, Sebastián Fernando; Corsten, Jan; Frankl, Nora; Pokrovskiy, Alexey; Skokan, Jozef (Siam, 2020)
      Confirming a conjecture of Gyarfas, we prove that, for all natural numbers k and r, the vertices of every r-edge-colored complete k-uniform hypergraph can be partitioned into a bounded number (independent of the size of ...
    • Daniilidis, Aris; Drusvyatskiy, Dmitriy (Siam, 2020)
      We construct examples of Lipschitz continuous functions, with pathological subgradient dynamics in both continuous and discrete time. In both settings, the iterates generate bounded trajectories and yet fail to detect any ...
    • Hernández Silva, Carla; Gómez Martínez, Yadrán; Ruz López, Damián; Silva Ugalde, Mauricio; Tecpan Flores, Silvia (Univ. Autónoma Baja California, 2020)
      The lack of physics teachers in Chile has been a cause for concern for the last 15 years. This study aims to identify and describe the key features of current physics teacher training programs in universities in the Council ...
    • Lombart, Maxime; Chauvin, Gael Epely; Rojo Rubke, Patricio; Lagadec, Eric; Delorme, Philippe; Beust, Herve; Bonnefoy, Mickael; Galicher, Raphael; Gratton, Raffaele; Mesa, Dino; Bonavita, Mariangela; Allard, France; Bayo, Alberto; Boccaletti, Anthony; Desidera, Silvano; Girard, Julien; Jenkins, James Stewart; Klahr, H.; Laibe, G.; Lagrange, Anne Marie; Lazzoni, C.; Marleau, Gabriel Dominique; Minniti, Dante; Mordasini, C. (EDP Science, 2020)
      Context. Dusty debris disks around pre- and main-sequence stars are potential signposts for the existence of planetesimals and exoplanets. Giant planet formation is therefore expected to play a key role in the evolution ...
    • Quezada, Rodrigo; Quintero Giraldo, Yurieth; Salgado Herrera, José; Estay, Humberto; García, Andreina (MDPI, 2020)
      Type of metal and metal-oxide NPs added to modify Thin-Film Composites Reverse Osmosis Membranes (TFC-RO) can alter their anti-biofouling properties by changing the dissolution process. The development of a mathematical ...
    • Sepúlveda, J.; Arancibia Hernández, Gloria; Molina, Eder; Gilbert, J. P.; Duda, M.; Browning, Julianna; Roquer, Tomás; Morata Céspedes, Diego; Ahrens, Bodo; Bracke, Rolf (Elsevier, 2020)
      Fractures and faults in granitic rocks play an important role in geothermal systems because they permit the circulation of hot fluids. However, the thermo-hydro-mechanical behavior of granitic rocks has predominantly been ...
    • Tirachini Hernández, Alejandro; Chaniotakis, Emmanouil; Abouelela, Mohamed; Antoniou, Constantinos (Elsevier, 2020)
      Studies in several cities indicate that ridesourcing (ride-hailing) may increase traffic and congestion, given the substitution of more sustainable modes and the addition of empty kilometers. On the other hand, there is ...
    • Becker, F.; Montealecre, P.; Rapaport Zimermann, Iván; Todinca, I. (Siam, 2020)
      The broadcast congested clique model (BClique) is a message-passing model of distributed computation where n nodes communicate with each other in synchronous rounds. First, in this paper we prove that there is a one-round, ...
    • Massone, Leonardo M.; Bass, Enrique (Elsevier, 2020)
      Dynamic shear amplification has been commonly studied in cantilever reinforced concrete wall systems, how-ever, coupling beams or slabs can generate axial loads that can modify the response. A parametric study is carried ...
