La macchina scenotecnica della visione: Robert Lepage e la sintesi tra meccanica e digitale nella messa in scena del Der ring des Nibelungen
2018
Robert Lepage impiega sulla sua scena tutti i dispositivi scenotecnici possibili, siano essi meccanici, elettrici o digitali, operando spesso con tecnologie che ricordano per la loro funzione le macchine scenotecniche del passato. Uno dei dispositivi più utilizzati da Robert Lepage, che connota gran parte della sua produzione, è la macchina girevole che costantemente modifica in tempo reale la scena. La macchina rotante non è però l’unico dispositivo che Lepage rimedia dalla scenotecnica teatrale. Muovendosi in una sorta di neo-barocco tecnologico, infatti, attinge a tutti quei dispositivi e macchine perfezionati nel XVII secolo da scenotecnici italiani, ibridandoli con nuove forme di dispo…
Sneaking into a Hotspot of Biodiversity: Coverage and Integrity of a Rhodolith Bed in the Strait of Sicily (Central Mediterranean Sea)
2022
Habitat mapping, physical characteristics and benthic community of a rhodolith bed in the Pelagie Islands (Strait of Sicily, Mediterranean Sea) were studied through Multi–Beam Echo–Sounder (MBES), Remotely Operated Vehicle (ROV) and grab samples. The geomorphological analysis revealed an articulated and wide rhodolith bed; video inspections highlighted a bed with high coverage, few sandy patches and with a prevalence of the boxwork morphotype. A total of 207 taxa with 876 specimens were identified, and Polychaeta was the dominant taxon. Linguimaera caesaris, a Lessepsian benthic amphipod, was recorded in all sampling sites, and its presence represents an input to deepen the benthic assembla…
Bilateral activations in operculo‐insular area show temporal dissociation after peripheral electrical stimulation in healthy adults
2018
Interhemispheric transfer is necessary for sensory integration and coordination of body sides. We studied how somatosensory input from one body side may reach both body sides. First, we investigated with 17 healthy adults in which uni‐ and bilateral brain areas were involved in consecutive stages of automatic sensory processing of non‐nociceptive peripheral stimulation. Somatosensory evoked fields (SEFs) to electrical stimulation were recorded with 306‐channel magnetoencephalography in two conditions. First, SEFs were registered following sensory radial nerve (RN) stimulation to dorsal surface of the right hand and second, following median nerve (MN) stimulation at the right wrist. Cortical…
More comprehensive proprioceptive stimulation of the hand amplifies its cortical processing
2021
Corticokinematic coherence (CKC) quantifies the phase coupling between limb kinematics and cortical neurophysiological signals reflecting proprioceptive feedback to the primary sensorimotor (SM1) cortex. We studied whether the CKC strength or cortical source location differs between proprioceptive stimulation (i.e., actuator-evoked movements) of right-hand digits (index, middle, ring, and little). Twenty-one volunteers participated in magnetoencephalography measurements during which three conditions were tested: 1) simultaneous stimulation of all four fingers at the same frequency, 2) stimulation of each finger separately at the same frequency, and 3) simultaneous stimulation of the fingers…
Identification of proprioceptive thalamocortical tracts in children: comparison of fMRI, MEG, and manual seeding of probabilistic tractography
2022
Publisher Copyright: © The Author(s) 2022. Published by Oxford University Press. Studying white matter connections with tractography is a promising approach to understand the development of different brain processes, such as proprioception. An emerging method is to use functional brain imaging to select the cortical seed points for tractography, which is considered to improve the functional relevance and validity of the studied connections. However, it is unknown whether different functional seeding methods affect the spatial and microstructural properties of the given white matter connection. Here, we compared functional magnetic resonance imaging, magnetoencephalography, and manual seedin…
Exploring Oscillatory Dysconnectivity Networks in Major Depression During Resting State Using Coupled Tensor Decomposition
2022
Dysconnectivity of large-scale brain networks has been linked to major depression disorder (MDD) during resting state. Recent researches show that the temporal evolution of brain networks regulated by oscillations reveals novel mechanisms and neural characteristics of MDD. Our study applied a novel coupled tensor decomposition model to investigate the dysconnectivity networks characterized by spatio-temporal-spectral modes of covariation in MDD using resting electroencephalography. The phase lag index is used to calculate the functional connectivity within each time window at each frequency bin. Then, two adjacency tensors with the dimension of time frequency connectivity subject are constr…
Mappings of finite distortion : boundary extensions in uniform domains
2015
In this paper, we consider mappings on uniform domains with exponentially integrable distortion whose Jacobian determinants are integrable. We show that such mappings can be extended to the boundary and moreover these extensions are exponentially integrable with quantitative bounds. This extends previous results of Chang and Marshall on analytic functions, Poggi-Corradini and Rajala and Akkinen and Rajala on mappings of bounded and finite distortion.
Towards a new marine structural model of Italy
2013
The exploitation of economic resources in marine environment and the assessment of natural hazards press a greater knowledge of the sea floor geology. Since the Structural Model of Italy was published in the 1991 by the CNR, new data have been collected concerning the marine geology of the sea floor surrounding Italy, also by means of up to date technologies (digital seismics, SBP Chirp, Multibeam). Data collected during the last decades in the frame of research programs as CROP MARE, CARG, morpho-bathymetric survey of the Tyrrhenian Sea, MAGIC, allow investigating the submerged geological structures with different temporal and spatial resolution. As consequence, at present marine geologist…
Motivation and Preferences of Visitors in the Bohemian Paradise UNESCO Global Geopark
2021
There are some localities in the Bohemian Paradise Geopark that suffer from temporal overtourism in the high season. On the other hand, more than half of the geopark is not so often visited by tourists, although very attractive geosites can be found there too. In the most visited localities, nature is damaged due to overloading of the tourist infrastructure, while elsewhere there is pressure driven by municipalities to increase the number of tourists. For this reason, we organized a large questionnaire survey in summer 2020, which aimed to reveal the motivation of visitors of the geopark and their preferences regarding the places visited. The questionnaire combined several research methods:…
Brain representation of action observation in human infants.
2015
Imitative learning has long been established as extremely important for early development. However, neural mechanisms involved in early imitative behaviours are still areas of active research. Neurophysiological and brain-imaging studies have been recently performed that provide initial evidence of brain activation associated with action observation in the first months of life. In this review we examine all studies exploring the effects of action observation on brain function assessed by means of non-invasive brain-mapping techniques. Seventeen papers were selected as a result of our literature search. The strongest evidence for a neural signature of action observation comes from studies ex…
