Alternative calculation of the physical mass of the p-meson por Morones Ramírez, Rubén, Mejía Rosales, Sergio

“…We have derived an expression for the physical mass and width of the ρ-meson in vacuum from its spectral function, calculated in the vector meson dominance model when a ρ 0 meson couples to two virtual pions π +–π −. The propagator is computed after evaluating the ρ-meson self-energy. …”

Effect of equivalent sites on the dynamics of bimetallic nanoparticles por Fernández Navarro, Carlos Javier, Gutiérrez Esparza, A. J., Montejano Carrizales, Juan Martín, Mejía Rosales, Sergio

“…Using a Sutton and Chen interatomic potential, we study the molecular dynamics of Au- Pd nanoparticles with an initial icosahedral structure at different temperatures and concentrations, where each relative concentration of the 561-atom particles was made by placing atoms of the same species at equivalent sites, in order to identify under which conditions the melting transition temperature appears for each particle. In addition, we compute global order parameters in order to correlate the obtained results with the caloric curves of each particle. …”

A Genetic Algorithm for the Bi-Level Topological Design of Local Area Networks por Waldorp, Lourens J., Camacho Vallejo, José Fernando, Mar Ortiz, Julio, López Ramos, Francisco, Pedraza Rodríguez, Ricardo

“…The Stackelberg-Genetic algorithm procedure deals with the fact that the follower’s problem cannot be optimally solved in a straightforward manner. The computational results obtained from two different sets of instances show that the performance of the developed algorithm is efficient and that it is more suitable for solving the bi-level problem than a previous Nash-Genetic approach.…”
