From different neurophysiological methods to conflicting pathophysiological views in migraine: a critical review of literature.

2014

Abnormal increased cortical responsivity to various types of stimuli plays a major role in migraine pathogenesis. Neurophysiological studies, however, have provided ambiguous findings of either hypo or hyper cortical excitability. This is why the term "dysexcitability" has been recently proposed to indicate a more general dysregulation of cortical excitability. The aims of this review are: (1) to provide existing knowledge and research advances in migraine pathophysiology; (2) to propose a unitary interpretation of apparently conflicting neurophysiological findings. Data of studies conducted in migraine through various evoked potentials techniques and non-invasive brain stimulation methods …

A Systematic Review of the Effectiveness of Non-Invasive Brain Stimulation Techniques to Reduce Violence Proneness by Interfering in Anger and Irrita…

2020

The field of neurocriminology has proposed several treatments (e.g., pharmacological, brain surgery, androgen-deprivation therapy, neurofeedback) to reduce violence proneness, but unfortunately, their effectiveness has been limited due to their side-effects. Therefore, it is necessary to explore alternative techniques to improve patients’ behavioural regulation with minimal undesirable effects. In this regard, non-invasive brain stimulation techniques, which are based on applying changing magnetic fields or electric currents to interfere with cortical excitability, have revealed their usefulness in alleviating the symptomatology of several mental disorders. However, to our knowledge, there …

IL PAGAMENTO “NECESSARIAMENTE INTERMEDIATO” DELL’OBBLIGAZIONE PECUNIARIA NELLA LEGISLAZIONE DI DERIVAZIONE EUROPEA: VERSO IL SUPERAMENTO DELL’UNICITÀ…

2015

Il lavoro muove dall’idea di analizzare il sistema delle regole che definiscono, sul piano dell’an, del quando e del quomodo, l’esattezza dell’adempimento che può definirsi (necessariamente) intermediato dell’obbligazione pecuniaria: nella vicenda solutoria della quale, cioè, risulti indefettibile, per volontà della legge o per scelta dei privati, l’interposizione di uno o più soggetti, altri rispetto al debitore e al creditore parti originarie del rapporto obbligatorio, con funzioni ausiliarie. Ciò al fine di saggiare la bontà della ipotesi ricostruttiva in base alla quale l’adempimento dell’obbligazione pecuniaria per mezzo di operazioni di pagamento intermediato non sia governato dalla l…

Energy and economic assessment of a small domestic wind turbine in Palermo

2016

The cost effectiveness of micro-wind technology is closely linked to the annual energy production plants, which strongly depends on the wind characteristics and on the morphological properties of the installation site. The power curve of a wind turbine, supplied by manufacturers, characterizes the theoretical energy performance that it should have at a particular site. The behavior of a wind turbine in the field is affected by the speed but also by wind direction variations. At each change of direction and speed, the turbine will try to adapt to new conditions and the phase transition negatively influences the energy production. In order to experimentally confirm what above mentioned, the a…

Biogeographic patterns of base-rich fen vegetation across Europe

2014

International audience; Questions: What is the distribution of base-rich fen vegetation and the specia- list species along European biogeographic regions? How do the gradients in spe- cies composition correlate to geography and climate at continental scale? What are the implications of such patterns for the classification of these habitats?Location: Fifteen countries of Central, Western and Northern Europe.Methods: We compiled a vegetation plot database of base-rich fens and related communities including vascular plants and bryophytes. The initial data set with 6943 plots was filtered according to the presence of specialists using discriminant analysis. We used DCA to analyse the correlatio…

Effects of Transcranial Direct Current Stimulation on Baseline and Slope of Prefrontal Cortex Hemodynamics During a Spatial Working Memory Task

2020

Background: Transcranial direct current stimulation (tDCS) has been shown to be an inexpensive, safe, and effective way of augmenting a variety of cognitive abilities. Relatively recent advances in neuroimaging technology have provided the ability to measure brain activity concurrently during active brain stimulation rather than after stimulation. The effects on brain activity elicited by tDCS during active tDCS reported by initial studies have been somewhat conflicted and seemingly dependent on whether a behavioral improvement was observed. Objective: The current study set out to address questions regarding behavioral change, within and between-participant designs as well as differentiatin…

Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory

2017

We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional informa…

Resting State EEG Directed Functional Connectivity Unveils Changes in Motor Network Organization in Subacute Stroke Patients After Rehabilitation

2022

Brain plasticity and functional reorganization are mechanisms behind functional motor recovery of patients after an ischemic stroke. The study of resting-state motor network functional connectivity by means of EEG proved to be useful in investigating changes occurring in the information flow and find correlation with motor function recovery. In the literature, most studies applying EEG to post-stroke patients investigated the undirected functional connectivity of interacting brain regions. Quite recently, works started to investigate the directionality of the connections and many approaches or features have been proposed, each of them being more suitable to describe different aspects, e.g.,…

Los planes complementarios de pensión como práctica de remuneración para directivos en compañías multinacionales y multilatinas

2016

Este trabajo de investigación tiene como objetivo general profundizar en el estudio de la remuneración de directivos y, particularmente, explorar el papel de los planes complementarios de pensión como práctica de remuneración de los directivos en las compañías multinacionales y/o multilatinas . Se parte de la experiencia del investigador, para mencionar como proposición inicial: la inclusión de esquemas de incentivos con fin específico, como por ejemplo los planes complementarios de pensión. Ya que estos pueden tener alto valor estratégico para la organización porque son considerados un instrumento fundamental de la compensación, puesto que permiten alinear los propósitos organizativos con …
