assessing genetic biodiversity and population structure of minor populations through the information provided by neutral molecular markers, allows determination of their extinction risk and to design strategies for their management and conservation. analysis of microsatellite loci is known to be highly informative in the reconstruction of the historical processes underlying the evolution and di...

We point out that if spatial information is encoded through linear operators Xi, or ‘infinite-dimensional matrices’ with an involution X∗ i = Xi then these Xi can only describe either continuous, discrete or certain ”fuzzy” space-time structures. We argue that the fuzzy space structure may be relevant at the Planck scale. The possibility of this fuzzy space-time structure is related to subtle f...

Técnicas de transientes de corrente potenciostáticos foram empregadas no estudo de processos de eletroredução de camadas superficiais formadas no cobalto policristalino em soluções contendo íons carbonato-bicarbonato. As análises dinâmicas do sistema, realizadas através de procedimentos de investigação paramétrica e de rotinas de ajuste não-lineares, demonstraram que os da dos obtidos sob numa ...

As we progress in the exciting area of treatment of acute myocardial infarction, two clinical trial methodologies coming from different philosophies and traditions must be considered. Smaller (200-3000 patient), detailed trials focusing on pathophysiology will be referred to as "mini-trials", while mammoth studies (10 000-50 000 patients) designed to measure mortality rates will be referred to ...

We prove that g (the groupwise density number) is smaller or equal to b, the successor of the minimal cardinality of an unbounded subset of ωω. This is true even for the version of g for groupwise dense ideals.

The strong weak truth table (sw) reducibility was suggested by Downey, Hirschfeldt, and LaForte as a measure of relative randomness, alternative to the Solovay reducibility. It also occurs naturally in proofs in classical computability theory as well as in the recent work of Soare, Nabutovsky and Weinberger on applications of computability to differential geometry. We study the sw-degrees of c....
