      Parametrically excited solitary waves emerge as localized structures in high-aspectratio free surfaces subject to vertical vibrations. Herein, we provide the first experimental characterization of the hydrodynamics of ...
    • Morales, Fernando; Paiva, Marcia; Bustos-Jiménez, Javier (Institute of Electrical and Electronics Engineers Inc., 2019)
      Robustness is a desired feature for any backbone network. As a minimum requirement to be considered robust, a network must remain connected after any single node or link failure, so that each node is able to communicate ...
    • Orellana, Felipe; Hormazábal Maluenda, Joaquín; Montalva, Gonzalo; Moreno, Marcos (MDPI, 2022)
      Coastal areas concentrate a large portion of the country's population around urban areas, which in subduction zones commonly are affected by drastic tectonic processes, such as the damage earthquakes have registered in ...

(Oxford University Press, 2020)
      The spatial distribution of metals reflects, and can be used to constrain, the processes of chemical enrichment and mixing. Using PHANGS-MUSE optical integral field spectroscopy, we measure the gas-phase oxygen abundances ...
    • Kim, Sang Won; Olivares Acuña, Marcelo; Weintraub, Gabriel Y. (Institute for Operations Research and the Management Sciences (INFORMS), 2014)
      The main advantage of a procurement combinatorial auction (CA) is that it allows suppliers to express cost synergies through package bids. However, bidders can also strategically take advantage of this flexibility, ...
    • Mizala Salcés, Alejandra; Ñopo, Hugo (Elsevier, 2016)
      How much are teachers paid in comparison to those in other professions in Latin America? How have these differences evolved in recent years? Is teachers' underpayment more pronounced in certain segments of the labor markets? ...
