Riella bialata Trab. (Riellaceae, Marchantiophyta): A new addition to the European liverwort flora
2013
[EN] Riella (Riellaceae, Sphaerocarpales) is a genus of aquatic liverworts with a disjunct worldwide distribution in areas of seasonal Mediterranean-type climates. Its centre of diversity is located in the Mediterranean basin, where about half the species number of the genus is concentrated. In the course of a worldwide revision of the genus Riella, plants from a monoicous species with wingless, not papillose and smooth involucres were found in two distant Iberian localities. These plants showed a geminate dorsal wing, unlike the single wing occurring in the remaining species of the genus. This character unambiguously assigns these populations to R. bialata, a species known to date from a s…
Continuous images of arcs: Extensions of Cornette's Theorem
2015
In [J.L. Cornette “Image of a Hausdorff arc” is cyclically extensible and reducible Trans. Am. Math. Soc., 199 (1974), pp. 253–267], Cornette proved that a locally connected Hausdorff continuum X is the continuous image of an arc if and only if each of its cyclic elements is the continuous image of an arc. Cyclic elements form a closed null cover of X by retracts of X. We generalize Cornette's result to closed null covers of X with a dendritic structure. We give examples to show that some of our conditions are necessary and we pose some open questions.
The production of western Greek amphorae in Agrigento (Southern Sicily): An archaeometric and archaeological characterisation of the late 6th-4th cen…
2022
This paper aims at an interdisciplinary, archaeological and archaeometric characterisation of the western Greek amphorae series produced in late Archaic and Classical-period Agrigento (southern Sicily). The research is based on a macroscopic examination, according to the standardised methods of Fabrics of the Central Mediterranean (FACEM), combined with petrographic analyses of 21 amphorae samples of presumed local fabric found in Agrigento itself. These were found in the artisanal area outside Porta V, in the excavations South of the temple of Zeus, and in several Sicilian consumption sites. Furthermore, a selection of 12 coarse ware samples and three tiles, all of supposed local manufactu…
Internazionalità e sviluppo locale di un'area intermedia
2013
Alla luce di della visione del documento “Progetto Aree Interne”, Ministero della Coesione Territoriale, il contributo vuole porre l’attenzione su alcuni comuni di un'area interna della Sicilia, in particolare della regione agrigentina, per indagare azioni finalizzate al perseguimento dello sviluppo locale degli stessi. I centri urbani individuati si presterebbero, pertanto, sulla scia di un fenomeno di “internazionalizzazione” che vede protagonista Cianciana, alla realizzazione di una rete di “alberghi diffusi” che possa innescare dinamiche di sviluppo locale, arginando il fenomeno dello spopolamento.
I paesaggi delle Aree Interne
2018
Il contributo affronta il tema delle Aree Interne dal punto di vista delle risorse paesaggistiche, naturali e culturali, confrontando la perifericità spaziale con quella relazionale di questi territori. Ponendo l'attenzione su quelle identità il cui valore e potenziale può rappresentare un catalizzatore di sviluppo, il contributo, dopo una dissertazione sull'argomento, individua alcune buone pratiche di sviluppo locale nelle Aree interne.
An Artificial Neural Network for 3D Localization of Brainstem Functional Lesions
2002
The human brainstem is a highly complex structure where even small lesions can give rise to a variety of symptoms and signs. Localizing the area of dysfunction within the brainstem is often a difficult task.To make localization easier, we have developed a neural net system, which uses 72 clinical and neurophysiological data inputs and displays it (using 5268 voxels) on a three-dimensional model of the human brainstem. The net was trained by means of a back-propagation algorithm, over a pool of 580 example-cases. Assessed on 200 test-cases, the net correctly localized 83.6% of the target voxels; furthermore the net correctly localized the lesion in 31/37 patients. Because our computer-assist…
Modelo Barcelona y política cultural: usos y abusos de la cultura por parte de un modelo emprendedor de desarrollo local
2015
El Modelo Barcelona de desarrollo local ha sido intensamente debatido· Desde su inicio en los años ochenta hasta la actualidad, diversos autores han analizado sus características como modelo, destacado sus éxitos y también sus puntos débiles. No obstante, menos atención ha recibido la relación que existe entre el modelo de desarrollo local y el modelo de política cultural, a pesar de que Barcelona también es internacionalmente conocida por su dinamismo cultural. De manera habitual, este modelo de política cultural ha sido interpretado como un instrumento en la agenda de desarrollo local. El presente artículo mostrará, a partir de análisis de diversos casos ejemplares, que la política cultur…
A first search for coincident gravitational waves and high energy neutrinos using LIGO, Virgo and ANTARES data from 2007
2013
A search for high-energy neutrinos coming from the direction of the Sun has been performed using the data recorded by the ANTARES neutrino telescope during 2007 and 2008. The neutrino selection criteria have been chosen to maximize the selection of possible signals produced by the self-annihilation of weakly interacting massive particles accumulated in the centre of the Sun with respect to the atmospheric background. After data unblinding, the number of neutrinos observed towards the Sun was found to be compatible with background expectations. The 90% CL upper limits in terms of spin-dependent and spin-independent WIMP-proton cross-sections are derived and compared to predictions of two sup…
Quantum localization and bound state formation in Bose-Einstein condensates
2010
We discuss the possibility of exponential quantum localization in systems of ultracold bosonic atoms with repulsive interactions in open optical lattices without disorder. We show that exponential localization occurs in the maximally excited state of the lowest energy band. We establish the conditions under which the presence of the upper energy bands can be neglected, determine the successive stages and the quantum phase boundaries at which localization occurs, and discuss schemes to detect it experimentally by visibility measurements. The discussed mechanism is a particular type of quantum localization that is intuitively understood in terms of the interplay between nonlinearity and a bou…
THE INFLUENCE OF SPATIAL COGNITION IN THEORY OF MIND AND CENTRAL COHERENCE TASKS: STUDY IN AUTISM
Autism Spectrum Disorder (ADS) is a severe developmental disability characterized by impairments in social interaction and communicative skills. Despite a growing research interest in the field, the causes of these impairments remain unknown. Two lines of research, Theory of Mind (ToM) and Central Coherence (CC), using experimental tasks such as visuo-spatial perspective Taking (VPT) and the local and global levels have suggested that visuo-spatial attention and spatial variables in the self-versus other recognition, may be the basis of the cognitive processes underlying social interaction. According to spatial attention, such as observed in the Unilateral spatial neglect (USN) may contribu…
