      Cruz Rivera, Erica; Ramírez Cabrera, Héctor; Vasilieva, Olga (Rocky Mountain Mathematics Consortium, 2019)
      Biologic characteristics of schooling fish species explain why the rates of harvesting in pelagic fisheries are not proportional to the existent stock size and may exhibit no variation between the periods of fish abundance ...

    • Cavity and other radial substructures in the disk around HD 97048 
      Van Der Plas, G.; Wright, C. M.; Ménard, F.; Casassus Montero, Simón; Cánovas, H.; Pinte, C.; Maddison, S. T.; Maaskant, K.; Avenhaus, H.; Cieza, L.; Pérez, S.; Ubach, C. (EDP Sciences, 2017)
