      Based on their effect on prey populations, predators can interact synergistically, additively, or antagonistically. Predator attraction by semiochemicals in response to herbivory is well documented; however, the possibility ...
    • Observation of localized modes at phase slips in two-dimensional photonic lattices 
      Szameit, Alexander; Molina Gálvez, Mario; Heinrich, Matthias; Dreisow, Felix; Keil, Robert; Nolte, Stefan; Kivshar, Yuri S. (OPTICAL SOC AMER, 2010-08-15)
      We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to observe a variety of effects, including ...

    • Pollinator-mediated selection in a specialized pollination system: matches and mismatches across populations 
      Nattero, J.; Cocucci, A. A.; Medel Contreras, Rodrigo (WILEY-BLACKWELL PUBLISHING, 2010-06-17)
      Most studies on pollinator-mediated selection have been performed in generalized rather than specialized pollination systems. This situation has impeded evaluation of the extent to which selection acts on attraction ...

      Mendizábal Emaldía, Fernando (Elsevier B.V., 2010-06-04)
      We studied the interaction between [AuI2] and I2 using ab initio methodology. We found that the changes around the equilibrium intermolecular distance Au l2 and in the interaction energy differences are sensitive ...
    • Onset of failure in argon by the effect of a shockwave: A molecular dynamics study 
      Loyola, Claudia; Davis, Sergio; Peralta, Joaquín; Gutiérrez Gallardo, Gonzalo (ELSEVIER SCIENCE BV, 2010-06-26)
      Molecular dynamic simulations of shockwaves in solid argon were performed. The simulation cell contains 51,840 atoms at 5 K interacting by means of a pairwise potential. The shockwave itself was introduced explicitly in ...
