A quantitative rationale for the evolution of the genetic code is developed considering the principle of minimal hardware. This principle defines an optimal code as one that minimizes for a given amount of information ...

Analysis for the homogeneity of the distribution of the second base of dinucleotides in relation to the first, whose bases are separated by 0, 1, 2, 21 nucleotide sites, was performed with the VIH-1 genome (cDNA), the ...

The success of targeted therapies fostered the development of increasingly specific and effective therapeutics for B-cell malignancies. However, cancer plasticity facilitates disease relapse, whereby intratumoral heterogeneity ...

This theoretical proposal applies evolutionary aesthetic, animal signalling and sexual selection to understand our artistic cognition, especially rock art aesthetics. Iconographic motifs, universally found in rock art, ...

The basic biology of the potential hantavirus reservoir rodents from Chile are reviewed. The taxonomy and systematics of five endemic Muridae species, the oryzomine Oligoryzomys longicaudatus (probably the primary reservoir), ...

We investigate the orbital and rotational evolution of the CoRoT-7 two-planet system, assuming that the innermost planet behaves like a Maxwell body. We numerically resolve the coupled differential equations governing the ...

Elliptical galaxies are the best systems to study the early star formation activity in the universe. This work aims to understand the formation and evolution of these objects through the study of the integrated properties ...
