Retrograde monosynaptic tracing reveals the temporal evolution of inputs onto new neurons in the adult dentate gyrus and olfactory bulb
2013
Identifying the connectome of adult-generated neurons is essential for understanding how the preexisting circuitry is refined by neurogenesis. Changes in the pattern of connectivity are likely to control the differentiation process of newly generated neurons and exert an important influence on their unique capacity to contribute to information processing. Using a monosynaptic rabies virus-based tracing technique, we studied the evolving presynaptic connectivity of adult-generated neurons in the dentate gyrus (DG) of the hippocampus and olfactory bulb (OB) during the first weeks of their life. In both neurogenic zones, adult-generated neurons first receive local connections from multiple typ…
NEFODO: un progetto di ricerca neurodidattica
2014
Il Progetto NE.FO.DO. (Neuroscienze ed Alta Formazione del Docente di Lingua Straniera) ha preso le mosse da tali assunti ed ha sviluppato una ricerca–intervento in due fasi. Nella prima, un gruppo docenti di LS, in servizio nelle scuole di Palermo, guidato dai ricercatori, ha validato alcuni percorsi di Neurodidattica della lingua straniera nella scuola primaria e nella scuola secondaria. Nella seconda fase, le metodologie validate sono diventate oggetto di un Master di II livello per docenti di LS, attivato in duplice edizione presso l’Università di Palermo con il supporto della Regione Sicilia sui fondi FSE 2011-2013. Durante il tirocinio a scuola, i corsisti del Master hanno avuto modo …

Understanding the influence of context in technology integration from teacher educators’ perspective
2021
The perspective of teachers is important for advancing the use of technology in classrooms. A considerable number of research studies have explained context in ways that have narrowed the understanding of its impact on successful technology integration. This study employs the Technological Pedagogical and Content Knowledge (TPACK) model as a lens in understanding factors influencing teachers’ integration of technology in classrooms. Data were collected using focused interviews of 19 teacher educators of three colleges of education from the southern part of Nigeria. The results reveal that among the level contexts, the meso level presented the most challenges to teachers’ efforts at integrat…
Analysis of data fusion techniques for multi-microphone audio event detection in adverse environments
2017
Acoustic event detection (AED) is currently a very active research area with multiple applications in the development of smart acoustic spaces. In this context, the advances brought by Internet of Things (IoT) platforms where multiple distributed microphones are available have also contributed to this interest. In such scenarios, the use of data fusion techniques merging information from several sensors becomes an important aspect in the design of multi-microphone AED systems. In this paper, we present a preliminary analysis of several data-fusion techniques aimed at improving the recognition accuracy of an AED system by taking advantage of the diversity provided by multiple microphones in …
Existence and uniqueness of nontrivial collocation solutions of implicitly linear homogeneous Volterra integral equations
2011
We analyze collocation methods for nonlinear homogeneous Volterra-Hammerstein integral equations with non-Lipschitz nonlinearity. We present different kinds of existence and uniqueness of nontrivial collocation solutions and we give conditions for such existence and uniqueness in some cases. Finally we illustrate these methods with an example of a collocation problem, and we give some examples of collocation problems that do not fit in the cases studied previously.
The Lr-Variational Integral
2022
AbstractWe define the $$L^r$$ L r -variational integral and we prove that it is equivalent to the $$HK_r$$ H K r -integral defined in 2004 by P. Musial and Y. Sagher in the Studia Mathematica paper The$$L^{r}$$ L r -Henstock–Kurzweil integral. We prove also the continuity of $$L^r$$ L r -variation function.
La salute dei migranti
2016
Da un’analisi della letteratura sulle condizioni sociali e sanitarie dell’immigrato, si possono determinare alcune aree critiche che necessitano di particolare attenzione soprattutto in termini di programmazione e di pianificazione di politica e di comunicazione socio-sanitaria. Possiamo suddividere queste aree in tre ambiti sommariamente delimitati da alcune condizioni patologiche, fisiologiche e sociali. - condizioni patologiche: malattie infettive (tb, mst, ...), malattie dermatologiche, disagio/malattie psichiatriche, traumi e incidenti, NCD; - condizioni fisiologiche: maternità, infanzia, vecchiaia; - condizioni sociali: prostituzione e tratta, abuso, detenzione; - aggravanti: disagio …
On condensation properties of Bethe roots associated with the XXZ chain
2015
I prove that the Bethe roots describing either the ground state or a certain class of "particle-hole" excited states of the XXZ spin-$1/2$ chain in any sector with magnetisation $\mathfrak{m} \in [0;1/2]$ exist and form, in the infinite volume limit, a dense distribution on a subinterval of $\mathbb{R}$. The results holds for any value of the anisotropy $\Delta \geq -1 $. In fact, I establish an even stronger result, namely the existence of an all order asymptotic expansion of the counting function associated with such roots. As a corollary, these results allow one to prove the existence and form of the infinite volume limit of various observables attached to the model -the excitation energ…
Three dimensional reductions of four-dimensional quasilinear systems
2017
In this paper we show that integrable four dimensional linearly degenerate equations of second order possess infinitely many three dimensional hydrodynamic reductions. Furthermore, they are equipped infinitely many conservation laws and higher commuting flows. We show that the dispersionless limits of nonlocal KdV and nonlocal NLS equations (the so-called Breaking Soliton equations introduced by O.I. Bogoyavlenski) are one and two component reductions (respectively) of one of these four dimensional linearly degenerate equations.
