Anthropic habitats as novel environments: consequences for evolution and conservation
(2017-07-14)
La transformación del medio natural en ambientes antropizados se ha dado a una escala sin precedentes en las últimas décadas. Estos nuevos ambientes presentan presiones selectivas distintas de las naturales, y las especies ...
EEG and MEG evidence of a predominant number code in bilinguals and its significance for developmental dyscalculia
(2017-07-11)
When talking about bilinguals it is evident that they manage with two codes for the language. However, bilinguals also manage two codes for the representation of numerical facts and, even balanced bilinguals, have a ...
Enhancing sampling in computational statistics using modified hamiltonians
(2016-11-18)
The Hamiltonian Monte Carlo (HMC) method has been recognized as a powerful sampling tool in computational statistics. In this thesis,we showthat performance ofHMCcan be dramatically improved by replacing Hamiltonians in ...

(2016-11-24)
The East-Atlantic flyway represents one of the main bird migration routes worldwide, comprising the Bay of Biscayas an inherent geographical barrier. So far, the significance of the Bay of Biscay for migrants and its ...
Elementary reactive processes of nitrogen and hydrogen on metal surfaces: A theoretical study
(2016-12-16)
We present a theoretical study of elementary reaction take place at solid surfaces. Calculations based on density functional theory (DFT) were performed to obtain the minimum energy structure of the Fe(111) surface as well ...
