Coincidence and common fixed points of weakly reciprocally continuous and compatible hybrid mappings via an implicit relation and an application
2015
Using the hybrid version of the notion of weakly reciprocal continuous mappings due to Gairola et al. [Coincidence and fixed point for weakly reciprocally continuous single-valued and multi-valued maps, Demonstratio Math. (2013/2014), accepted], we prove a coincidence and common fixed point theorem for a hybrid pair of compatible mappings via an implicit relation. Our main result improves and generalizes a host of previously known theorems. As an application, we give a homotopy theorem which supports our main result.

Autorità indipendenti e separazione dei poteri: un'analisi empirica delle nomine e dei mandati
2023
Il presente lavoro intende esaminare i profili di indipendenza «strutturale» che caratterizzano le autorità amministrative indipendenti al fine di stabilire se le modalità di nomina, l’influenzabilità politica e i termini del mandato dei componenti possono condizionare in maniera significativa il concreto esercizio dei compiti affidati. Nel testo si ricostruisce il regime normativo delle procedure e dei requisiti di nomina degli organi di vertice delle autorità. Si esaminano poi i dati relativi ai profili professionali e alla caratterizzazione politica dei componenti, allo scopo di determinare se questi elementi possiedono un’influenza all’interno della procedura di designazione, individuan…
Measuring the Rate of Information Exchange in Point-Process Data With Application to Cardiovascular Variability
2022
The amount of information exchanged per unit of time between two dynamic processes is an important concept for the analysis of complex systems. Theoretical formulations and data-efficient estimators have been recently introduced for this quantity, known as the mutual information rate (MIR), allowing its continuous-time computation for event-based data sets measured as realizations of coupled point processes. This work presents the implementation of MIR for point process applications in Network Physiology and cardiovascular variability, which typically feature short and noisy experimental time series. We assess the bias of MIR estimated for uncoupled point processes in the frame of surrogate…
O Brasil na rota das migrações internacionais qualificadas espanholas no século XXI
2018
In order to understand recent migration, it is crucial to analyze the migratory modalities such as skilled international migration to Brazil, especially considering the ongoing transnational economic processes and their effects on the corresponding societies. Therefore, this article seeks to understand how the migratory dynamics of highly skilled Spanish professionals to the country are established taking into account the theoretical contribution of the circulation of brains and the category of knowledge workers. For this purpose, information from Brazilian?s Ministry of Labor is used on labor authorizations, financial contributions and insertion in the formal market in Spain; as well as da…
Influence of Ge doping level on the EPR signal of Ge(1), Ge(2) and E'Ge defects in Ge-doped silica
2011
Abstract We present an experimental investigation on the Ge doping level dependence of the Electron Paramagnetic Resonance (EPR) signal spectral features of the Ge(1), Ge(2) and E'Ge defects induced in Ge doped silica. We have studied samples produced by sol–gel or PCVD techniques and doped with different amounts of Ge up to 20% by weight. The samples were gamma or beta ray irradiated and successively they were thermally treated to isolate the EPR signals of the different point defects. The data show that the EPR line shapes of the Ge(1) and the Ge(2) centers are progressively modified for doping level higher than 1%, whereas the line shape of the E'Ge defect appears independent from the do…
Dependence of the emission properties of the germanium lone pair center on Ge doping of silica
2011
We present an experimental investigation regarding the changes induced by the Ge doping level on the emission profile of the germanium lone pair center (GLPC) in Ge doped silica. The investigated samples have been produced by the sol-gel method and by plasma-activated chemical vapor deposition and have doping levels up to 20% by weight. The recorded photoluminescence spectra show that the GLPC emission profile is the same when the Ge content is lower than ∼ 1% by weight, whereas it changes for higher doping levels. We have also performed Raman scattering measurements that show the decrease of the D1 Raman band at 490 cm( - 1) when the Ge content is higher than 1% by weight. The data suggest…

Vida más allá del PowerPoint: Un esfuerzo por superar la presente involución tecnológica de los procesos de enseñanza-aprendizaje hacia prácticas doc…

La tradicional clase magistral se ha vestido o disfrazado, en el marco de la revolución digital, con tecnología para convertirse, en la pràctica, en una versión más cara y compleja, con grandes costes para los centros de enseñanza y universidades. Sigue siendo una lectura comentada por el profesor donde el alumno no tiene un papel activo, ya que es el profesor el que se considera que tiene el conocimiento, y trabaja. Los alumnos pueden preguntar si se considera necesario, ahora el estudiante no necesita ya tomar apuntes siquiera, las diapositivas de las editoriales carecen casi de erratas… Se propone con este poster dar un salto cualitativo siguiendo metodologías del mundo anglosajón para p…
