• Understanding contagion dynamics through microscopic processes in active Brownian particles 

      Norambuena, Ariel [Univ Mayor, Ctr Invest DAiTA LAB, Fac Estudios Interdisciplinarios, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Ciencias, Ctr Invest DAiTA Lab, Chile]; Guzman-Lastra, Francisca [Univ Mayor, Fac Ciencias, Ctr Invest DAiTA Lab, Chile] (Nature Publishing Group, 2020-11)
      Together with the universally recognized SIR model, several approaches have been employed to understand the contagion dynamics of interacting particles. Here, Active Brownian particles (ABP) are introduced to model the ...
    • Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells 

      Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Ramírez, Max; Varas, Alejandro; Rogan, José (Chile. Universidad Mayor, 2020)
      The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
    • V4142 Sgr: Double periodic variable with an accretor surrounded by the accretion disk's atmosphere 

      Rosales, JA.; Mennickent, RE.; Djurasevic, G.; Araya, I. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Cure, M.; Schleicher, DRG.; Petrovic, J. (EDP SCIENCES S A, 2023-02-10)
      Context. A detailed study of the close interacting binary V4142 Sgr, based on photometric and spectroscopic analyses, indicates that this system belongs to the enigmatic class of Algol-like variables exhibiting a long ...
