Conditional betas and Market re-definition: Revisiting the capital asset pricing model with Mexican data
Published 2012“…The results suggested, however, that it is necessary to allow for time variations in betas as well in order to explain the variations of the monthly average returns. A size effect was also found, although it is not very important. In spite of the empirical support found for the conditional CAPM over the static CAPM, both specifications explain about half of the monthly average return variation, which calls for differences in the pricing of risk between developed and emerging countries…”

Two-stage melting of au-pd nanoparticles
Published 2006“…We found that the melting transition temperature has a strong dependence on the relative concentrations of the atomic species. We also found that, previous to the melting transition, the outer layer of the nanoparticle gets disordered in what can be thought as a premelting stage, where Au atoms near the surface migrate to the surface and remain there after the particle melts as a whole. …”

Practical methods for the morphological recognition and definitionof genera, with a comment on polychaetes (Annelida)
Published 2020“…Human mind detects patterns by comparative morphology and this explains why experience is extremely important in taxonomy. Analogy is also involved, because by understanding how character patterns help recognizing taxonomic groups, these patterns can be extrapolated in less well-known groups. …”

Evaluación teórica de la reflectancia en capas delgadas de Al/SiO2 depositadas mediante sputtering para aplicaciones en recubrimientos ópticos
Published 2021“…The thickness of the coating where these values were obtained, was the one corresponding to the 80 nm interval. It was also possible to verify certain relationships between the roughness and the thickness of the sample, as well as the increase in reflectance, as the thickness of the coating increased, until reaching a maximum in the aforementioned interval.…”
