Given two positive definite matrices A and B, a well known result by Gelfand, Naimark and Lidskii establishes a relationship between the eigenvalues of A and B and those of AB by means of majorization inequalities. In this ...

Tradicionalmente se ha abordado el estudio de la variación morfológica mediante técnicas estadísticas uni y multivariadas aplicadas principalmente a proporciones calculadas sobre distancias lineales entre puntos anatómicos ...

Though banana is a tropical crop, the Argentinean Northeastern Province of Formosa has extensively promoted its production. Genetic variation was assessed by the Amplified Fragment Length Polymorphism (AFLP) in a set of ...

Generalized Procrustes analysis (GPA) is a multivariate technique that involves transformations of data matrices to provide optimal comparability. We propose GPA to quantify the concordance among sets of variables that ...

BackgroundSymmetry of biological structures can be thought as the repetition of their parts in different positions and orientations. Asymmetry analyses, therefore, focuses on identifying and measuring the location and ...

The Argentinean Pampean plain has been under agriculture and farming since colonial times. Its loessic soils have the highest production capacity in Argentina, in spite of which it is suffering extensive land use change ...

Nuevas biotecnologías permiten obtener información para caracterizar materiales genéticos a partir de múltiples marcadores, ya sean éstos moleculares y/o morfológicos. La ordenación del material genético a través de la ...
