Tris{2-[(2-aminobenzylidene)amino]ethyl}amine
Published 2010“…With such an arrangement, one amine H atom forms an S(6) motif through a weak N—HN hydrogen bond with the imine N atom, while the other is engaged in an intermolecular N—H contact involving the benzene ring of a neighbouring molecule related by inversion. The benzene rings also participate in an intramolecular C— H contact of similar strength. …”

Effects of pericytes and colon cancer stem cells in the tumor microenvironment
Published 2019“…In recent years, it has been shown that the main reason for drug resistance is the presence of colon cancer stem cells (CSC). Pericytes are also capable of tumor homing and are important cellular components of the tumor microenvironment (TME), contributing to the formation of vessels and promoting metastasis; however, they have not been considered very important as a therapeutic target in cancer. …”

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. …”

Atenuación, género e intensificación en la perspectiva mediática del discurso político. El compromiso de castidad entre los adolescentes de Nuevo León, México. (2011) = Atenuation,...
Published 2017“…The focus is on the analysis of the pragmatic strategies of attenuation and intensification in argumentation (Zárate 2012; 2015; Toulmin, Rieke & Janik 1979; Gilbert 1997), and also the possible relations between evidentiality and epistemicity (de Haan 1999), as well as discursive control mechanisms (Foucault 2008). …”
