Interventions, Productions and Collaborations:the relationship between RAI and visual artists
No full textOn the 17th May 1952, before RAI Radiotelevisione Italiana Studios began their regular broadcast from Milan, the Spatialist painter and sculptor Lucio Fontana broadcast his own experimental ‘artwork’ on Italian television, beginning a fruitful relationship between RAI and visual artists. For some, it provided careers as designers and art directors, such as the painter Mario Sasso and the Arte Povera artist Pino Pascali, while for others, who were given unique access to RAI’s television apparatus, it was an opportunity to explore their own artistic experimentations with an expensive and exclusive medium, such as Carlo Quartucci and Gianni Toti. RAI also hosted seminal artists’ performances on screen including John Cage and Fabio Mauri. This article, based on documents and interviews collected during the Arts and Humanities Research Council funded project REWINDItalia, discusses these and other seminal cases as well as tracing and assessing the history of this fruitful and complex exchange between RAI and visual artists

Toti Scialoja e Pino Pascali: contrappunto
No full textIl contributo approfondisce il dialogo fra Toti Scialoja (1914-1998) e Pino Pascali (1935-1968) nato nella aule dell'accademia di Roma, dove Scialoja insegnava e Pascali si iscrive nel 1955-56. A questa altezza cronologica Pascali è poco più che ventenne e Scialoja è un pittore già noto e apprezzato sulla scena artistica internazionale, con la quale instaura rapporti diretti in occasione della sua mostra personale alla Cathrine Viviano Gallery di New York, rivelatasi fondamentale per condurre alla maturità la propria pittura.
La febbrile ricerca sulla materia pittorica di questi anni persuade i giovani allievi dell’accademia e, nello specifico, il giovane Pascali che, fin da subito, si confronta con tecniche e materiali inusuali, da cui derivano visioni inaspettate e cariche di vitalità.
Se per Scialoja i viaggi americani sono indispensabili per emancipare la propria ricerca, per Pascali gli Stati Uniti d’America restano un miraggio, restituito nella fascinazione per le ambientazioni urbane d’oltreoceano, i film dei gangster e soprattutto l’opera di Jasper Johns che ha modo di vedere alla Biennale di Venezia del 1964.
Alla luce della distanza generazionale e delle attitudini personali, il contributo restituisce il dialogo fra due artisti fra il 1955 e il 1964, evidenziando confluenze e differenze di temi, processi e immaginari
A perturbative approach to the reconstruction of the eigenvalue spectrum of a normal covariance matrix from a spherically truncated counterpart
No full textIn this paper we propose a perturbative method for the reconstruction of the covariance matrix of a multinormal distribution, under the assumption that the only available information amounts to the covariance matrix of a spherically truncated counterpart of the same distribution. We expand the relevant equations up to the fourth perturbative order and discuss the analytic properties of the first few perturbative terms. We finally compare the proposed approach with an exact iterative algorithm (discussed in Palombi et al. (2017)) in the hypothesis that the spherically truncated covariance matrix is estimated from samples of various sizes

A knowledge discovery methodology for semantic categorization of unstructured textual sources
No full textWe describe a methodology for identifying characterizing terms from a source text or paper and automatically building an ontology around them, with the purpose of semantically categorizing a paper corpus where documents sharing similar subjects may be subsequently clustered together by means of ontology alignment. We first employ a Natural Language Processing pipeline to extract relevant terms from the source text, and then use a combination of a pattern-based and machine-learning approach to establish semantic relationships among those terms, with some user's feedback required in-between. This methodology for discovering characterizing knowledge from textual sources finds its inception as an extension of PRAISED, our abbreviation discovery framework, in order to enhance its resolution capabilities. By moving from a paper-by-paper, mainly syntactical process to a corpus-based, semantic approach, it was in fact possible to overcome earlier limits of the system related to abbreviations whose explanation could not be found within the same paper they were cited in. At the same time, though, the methodology we present is not tied to this specific task, but is instead of relevance for a variety of contexts, and might therefore be used to build a stand-alone system for advanced knowledge extraction and semantic categorization. © 2012 IEEE
Effective seismic strengthening and monitoring of a masonry vault by using Glass Fiber Reinforced Cementitious Matrix with embedded Fiber Bragg Grating sensors
No full textThe research proposes the combined use of a Glass Fiber Reinforced Cement Matrix (GFRCM) composite with an integrated fiber optic sensing system for innovative seismic retrofitting of masonry vaults. The need of eco-compatibility of bonding material with masonry support implies the use of Hydraulic Lime Mortar (HLM) as bonding matrix that, in contrast, is characterized by lower adhesion capacity respect to polymeric resins and not well-known carrying-load properties. Hence, monitoring of the operating features of the GFRCM reinforcement has been pursued with an advanced fiber optic sensing system realized through Fiber Bragg Grating (FBG) sensors. The use of FBG sensors is justified by a large number of advantages such as small sensor dimensions, low weight as well as high static and dynamic resolution of measured values, distributed sensing feature allowing to detect anomalies in load transfer between reinforcement and substrate. Specifically, the proposed retrofitting and monitoring technique is designed and applied to an old masonry pavilion vault. A nonlinear finite element model of the reinforced structure is developed in order to quantify the effectiveness of the GFRCM strengthening layer and to derive the convenient position of the optic fibers for a correct monitoring of the reinforced vault. An experimental campaign is carried out in order to verify the proper behavior of the proposed strengthening and sensing strategy
A framework for semi-automatic identification, disambiguation and storage of protein-related abbreviations in scientific literature
No full textWe propose a framework for identifying, disambiguating and storing protein-related abbreviations as found in the full texts of scientific papers, in order to build and maintain a publicly available abbreviation repository via a semi-automatic process. This process involves information extraction methods and techniques for acronym identification and resolution, based on lexical clues and syntactical, largely domain-independent criteria. A dictionary and an ontology for proteins provide the means for matching and disambiguating the biological entities. User feedback is gathered at the end of the process and the confirmed entries are then stored and made available to the scientific community for further reviewing. © 2011 IEEE
Knowledge discovery from textual sources by using semantic similarity
No full textWe propose a methodology to automatically discover characterizing knowledge from textual sources, with the purpose of semantically categorizing them and clustering them together according to their subjects. Such a methodology is based upon several challenging steps, like terminology extraction and disambiguation, semantic similarity identification via ontology alignment, and a core pattern-based strategy for automatic ontology building. This methodology was originally devised as an extension of PRAISED, our abbreviation identification and resolution proposal, with the purpose of allowing us to resolve previously unresolvable abbreviations, whose explanation either escapes the system's proximity-based approach or is not found within the very source text they are featured in. By moving from a paper-by-paper, mainly syntactical process to a corpus-based, semantic approach, it will be in fact possible to dramatically enhance our system in terms of its resolution capabilities. Nevertheless, the strategy we present here is not tied to this specific task, but is instead of relevance for a variety of contexts, and might therefore find a far wider applicability for other advanced knowledge extraction and discovery systems.

Adult Myeloid Leukaemia and Radon Exposure: a Bayesian Model for a Case-Control Study with Error in Covariates
No full textThe possible association between radon exposure in dwellings and adult myeloid leukaemia had been explored in an Italian province by a case-control study. A total of 44 cases and 211 controls were selected from death certificates file. No association had been found in the original study (OR =0.58 for >185 vs <=80Bq/cm). Here we reanalyse the data taking into account the measurement error of radon concentration and the presence of missing data. A Bayesian hierarchical model with error in covariates is proposed which allows appropriate imputation of missing values.
The general conclusion of no evidence of association with radon does not change, but a negative association is not observed anymore (OR =0:99 for ¿185 vs 680Bq=cm). After adjusting for residential house radon and gamma radiation, and for the multilevel data structure, geological features of the
soil is associated with adult myeloid leukaemia risk (OR =2:14; 95 per cent Cr.I. 1.0–5.5)
