Diversities, hyperconvexity and fixed points
(Elsevier, 2014-01)
Diversities have been recently introduced as a generalization of metrics for which a rich tight span theory could be stated. In this work we take up a number of questions about hyperconvexity, diversities and fixed points ...

El Reto de la Equidad en las Políticas Sanitarias Dirigidas al Pueblo Gitano en España
(Global Journal of Community Psychology Practice, 2016)
En este artículo abordamos la contribución de la psicología comunitaria en la formulación de políticas de salud pública transformadoras dirigidas al pueblo gitano. La brecha en salud entre la minoría gitana y el resto de ...

Inactivation of a heterocyst-specific invertase indicates a principal role of sucrose catabolism in heterocysts of Anabaena sp.
(American Society for Microbiology, 2010)
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that carries out N2 fixation in specialized cells called heterocysts, which exchange nutrients and regulators with the filament's vegetative cells that perform ...

On the classifying space for proper actions of groups with cyclic torsion
(De Gruyter, 2014-01)
In this paper we introduce a common framework for describing the topological part of the Baum-Connes conjecture for a wide class of groups. We compute the Bredon homology for groups with aspherical presentation, one-relator ...

ChIP analysis unravels an exceptionally wide distribution of DNA binding sites for the NtcA transcription factor in a heterocyst-forming cyanobacterium
(BioMed Central, 2014)
Background The CRP-family transcription factor NtcA, universally found in cyanobacteria, was initially discovered as a regulator operating N control. It responds to the N regime signaled by the internal 2-oxoglutarate ...

Solving molecular flexible docking problems with metaheuristics: A comparative study
(Elsevier, 2015)
The main objective of the molecular docking problem is to find a conformation between a small molecule (ligand) and a receptor molecule with minimum binding energy. The quality of the docking score depends on two factors: ...

Population Dynamics P Systems on CUDA
(Springer, 2012)
Population Dynamics P systems (PDP systems, in short) provide a new formal bio-inspired modeling framework, which has been successfully used by ecologists. These models are validated using software tools against actual ...

Tolerância e sensibilidade térmica em anfíbios
(Universidad de São Paulo. Brasil, 2012)
Atualmente vivemos um cenário de alterações climáticas em que se prevê o aumento da temperatura média e da ocorrência de picos de temperatura extrema, entre outros. Sabendo que os anfíbios correspondem a uma parte ...

Spatio-temporal nested patterns in macroinvertebrate assemblages across a pond network with a wide hydroperiod range
(Springer Nature, 2011)
Nestedness has been widely used to measure the structure of biological communities and occurs when species-poor sites contain subsets of species-rich ones. Here, we examine nested patterns across the macroinvertebrate ...

Universal asymptotic behavior in nonlinear systems driven by a two-frequency forcing
(American Physical Society, 2013)
We examine the time-dependent behavior of a nonlinear system driven by a two-frequency forcing. By using a nonperturbative approach, we are able to derive an asymptotic expression, valid in the long-time limit, for the ...
