Today, several pharmaceutic and non-pharmaceutic approaches exist to treat psychiatric and neurological diseases. Because of the lack of treatment procedures that are medication free and without severe side effects, transcranial direct current stimulation (tDCS) and aerobic exercise (AE) have been tested to explore the potential for initiating and modulating neuroplasticity in the human brain. Both tDCS and AE could support cognition and behavior in the clinical and non-clinical context to improve the recovery process within neurological or psychiatric conditions or to increase performance. As these techniques still lack meaningful effects, although they provide multiple beneficial opportun…

Suitability of chloroplast LSU rDNA and its diverse group I introns for species recognition and phylogenetic analyses of lichen-forming Trebouxia alg…

2009

To date, species identification of lichen photobionts has been performed principally on the basis of microscopic examinations and molecular data from nuclear-encoded genes. In plants, the chloroplast genome has been more readily exploited than the nuclear genome for systematic investigations. At the present time, very little information is available about the chloroplast genome of lichen-forming algae. For this reason, we have sequenced a portion of the gene encoding for the chloroplast large sub-unit rRNA (LSU rDNA) as a new molecular marker. Sequencing of the chloroplast LSU rDNAs revealed the existence of an unusual diversity of group I introns (a total of 31) within 15 analyzed Trebouxi…

Stationary heat flux profile in turbulent helium II in a semi-infinite cylindrical channel

2012

In this paper we determine a set of solutions for a system of partial dif- ferential equations describing stationary heat flux in a semi-infinite cylindrical channel filled with turbulent superfluid helium. This study uses a continuous model for liquid helium II, derived from Extended Thermodynamics, in which the heat flux q is a fundamental variable. The influence of the vortex line den- sity on the radial distribution of the heat flux is especially discussed.

Inductive inference of recursive functions: Qualitative theory

2005

This survey contains both old and very recent results in non-quantitative aspects of inductive inference of total recursive functions. The survey is not complete. The paper was written to stress some of the main results in selected directions of research performed at the University of Latvia rather than to exhaust all of the obtained results. We concentrated on the more explored areas such as the inference of indices in non-Goedel computable numberings, the inference of minimal Goedel numbers, and the specifics of inference of minimal indices in Kolmogorov numberings.

Nuclear effects in neutrino-nucleus interactions: the role of spectral functions

2019

En esta tesis hemos estudiado la interacción neutrino-núcleo, en el régimen cuasielástico, haciendo un especial énfasis en la importancia de las correcciones nucleares. Motivación En el estudio de la física de oscilaciones de neutrinos, los desafíos más importantes que se presentan en la actualidad son (i) medir el valor de la fase de la violación de la simetría CP y (ii) discernir entre jerarquía normal o invertida en el respeto de masas de los neutrinos. Los futuros experimentos diseñados para resolver estas (y otras) cuestiones, incluyendo posibles descubrimientos de Física más allá del Modelo Estándar, sobre todo DUNE y T2HK, contarán con una estadística muy alta, asi…

EPPS16 - First nuclear PDFs to include LHC data

2017

We present results of our recent EPPS16 global analysis of NLO nuclear parton distribution functions (nPDFs). For the first time, dijet and heavy gauge boson production data from LHC proton-lead collisions have been included in a global fit. Especially, the CMS dijets play an important role in constraining the nuclear effects in gluon distributions. With the inclusion of also neutrino-nucleus deeply-inelastic scattering and pion-nucleus Drell-Yan data and a proper treatment of isospin-corrected data, we were able to free the flavor dependence of the valence and sea quark nuclear modifications for the first time. This gives us less biased, yet larger, flavor by flavor uncertainty estimates. …

Le Nazioni Unite

2006

Nel saggio, natura, funzioni e poteri delle Nazioni Unite sono analizzati in una prospettiva storica. In particolare, sono esaminati, per un verso, l''influenza che l''attività dell''Organizzazione (sia normativa che operativa) ha esercitato sullo sviluppo della società internazionale e del suo diritto e, in senso inverso, i condizionamenti degli assetti politici ed economici della società internazionale sul funzionamento dell''Organizzazione. Pertanto, ad una prima parte descrittiva degli organi e delle procedure, seguono due parti, di cui la prima relativa alla vita dell''Organizzazione dalla nascita alla fine della guerra fredda, ed una seconda che parte dalla caduta del muro di Berlino …

Fractional-order theory of thermoelasticicty. I: Generalization of the Fourier equation

2018

The paper deals with the generalization of Fourier-type relations in the context of fractional-order calculus. The instantaneous temperature-flux equation of the Fourier-type diffusion is generalized, introducing a self-similar, fractal-type mass clustering at the micro scale. In this setting, the resulting conduction equation at the macro scale yields a Caputo's fractional derivative with order [0,1] of temperature gradient that generalizes the Fourier conduction equation. The order of the fractional-derivative has been related to the fractal assembly of the microstructure and some preliminary observations about the thermodynamical restrictions of the coefficients and the state functions r…

Food predictability determines space use of endangered vultures: implications for management of supplementary feeding.

2013

Understanding space use of free-living endangered animals is key to inform management decisions for conservation planning. Like most scavengers, vultures have evolved under a context of unpredictability of food resources (i.e. exploiting scattered carcasses that are intermittently available). However, the role of predictable sources of food in shaping spatial ecology of vultures has seldom been studied in detail. Here, we quantify the home range of the Egyptian vulture (Neophron percnopterus), a long-lived raptor which has experienced severe population decline throughout its range and is qualified as endangered worldwide. To this end six adults were tracked by satellite telemetry in Spain d…
