NoTube – making TV a medium for personalized interaction
In this paper, we introduce NoTube’s vision on deploying semantics in interactive TV context in order to contextualize distributed applications and lift them to a new level of service that provides context-dependent and personalized selection of TV content. Additionally, lifting content consumption from a single-user activity to a community-based experience in a connected multi-device environment is central to the project. Main research questions relate to (1) data integration and enrichment - how to achieve unified and simple access to dynamic, growing and distributed multimedia content of diverse formats? (2) user and context modeling - what is an appropriate framework for context modeling, incorporating task-, domain and device-specific viewpoints? (3) context-aware discovery of resources - how could rather fuzzy matchmaking between potentially infinite contexts and available media resources be achieved? (4) collaborative architecture for TV content personalization - how can the combined information about data, context and user be put at disposal of both content providers and end-users in the view of creating extremely personalized services under controlled privacy and security policies? Thus, with the grand challenge in mind - to put the TV viewer back in the driver's seat – we focus on TV content as a medium for personalized interaction between people based on a service architecture that caters for a variety of content metadata, delivery channels and rendering devices
The touristic sector in the 5G technology era: the 5G-TOURS project approach
5G mobile networks are designed to fulfill very stringent requirements and support new vertical use cases. This transition to a vertical oriented delivery model will have a strong impact in the touristic sector. In this context, the "touristic city node" of 5G-TOURS, built in the city of Turin, aims at exploiting the potential of the media vertical. The objective is to develop an innovative tourism concept based on complementary and linked trials for five specific use cases. The trials will promote an overall integrated indoor/outdoor immersive experience to the visitors using any possible device, enhancing the accessibility to the technology especially for disadvantaged and disabled people. They will also utilize 5G to drive "remote tourism" based on AR/VR experiences and bridge the gap between the physical and virtual worlds for tourism. This paper provides an overview of the 5G technology deployed in the touristic node, explaining the different services to be provided and discussing the need of 5G technology to support this vision. This work also assesses the business potential of each of the considered use cases, corroborating their potential in the context of future network services.This work was supported in part by the European Commission under the 5G-TOURS: SmarT mObility, media and e-health for toURists and citizenS (H2020-ICT-2018-2020 call, grant number 856950)
Standard model anomalies: Lepton flavour non-universality and lepton g-2
We critically analyze the body of results that hints to the existence of New
Physics from possible violations of lepton universality observed by the LHCb
experiment in the ratios and to the lepton
anomalies. The analysis begins with a theoretical, in depth, study of the
ratios and as well as the process . Here we consider the impact of complex Wilson coefficients and
derive constraints on their imaginary and real parts. We then move to a
comprehensive comparison with experimental results. We show that, by fitting a
single Wilson coefficient, the deviations from the Standard Model are at the
level when including only the hadronic insensitive observables
while it increases to when including also the hadronic sensitive
ones. When switching on all relevant Wilson coefficients and combining both
hadronic sensitive and insensitive data into the fit, the deviation from the
Standard Model peaks at 7.2 and decreases at the level if
we assume that the central values of and are taken to be
unity. We further estimate the non-perturbative long distance hadronic
contributions and show that their inclusion still requires New Physics to fit
the data. We then introduce the lepton anomalies results. Different
theoretical models are considered that can explain the discrepancies from the
Standard Model. In the final part of our work we estimate the impact of the
forthcoming data from LHCb (coming from LHC Run3) and Belle II, when it will
have accumulated about
Dichiarazione ICRP sulle reazioni tissutali ed effetti immediati e tardivi delle radiazioni nei tessuti e negli organi normali - Dosi soglia per le reazioni tissutali nell’ambito della radioprotezione
La pubblicazione ICRP 118 riesamina gli effetti precoci e tardivi delle radiazioni ionizzanti nei diversi organi ed apparati e fornisce stime aggiornate sulle dosi soglia per l'induzione delle
numerose reazioni tissutali analizzate. In particolare, a seguito dei progressi nelle conoscenze radiobiologiche e cliniche, pubblicati in numerosi testi specialistici, vengono dettagliatamente presentate le evidenze che hanno condotto alle modificazioni, rispetto alle Raccomandazioni ICRP 103/2007, nella individuazione delle dosi soglia per la induzione della cataratta e delle patologie del sistema
circolatorio da parte delle radiazioni ionizzanti. A queste rilevanti considerazioni si affiancano gli approfonditi aggiornamenti sulle conoscenze radiobiologiche e cliniche e le integrazioni delle dosi soglia, individuate in modo più articolato rispetto alle precedenti pubblicazioni, per tutte le altre reazioni tissutali, che rendono questo documento un indispensabile strumento di lavoro e di analisi per tutti coloro
che si occupano di radioprotezione, con particolare riferimento agli specialisti di radioprotezione medica. La traduzione in italiano dell’intero testo vuole facilitare la diffusione delle peculiari
informazioni contenute nella pubblicazione e motivare una sempre più approfondita ricerca in questo settore che indubbiamente contribuisce a ridurre i rischi derivanti dall’esposizione
alle radiazioni ionizzanti.
La realizzazione della versione italiana di questa pubblicazione ha richiesto un notevole impegno qualitativo e quantitativo ed è stata possibile per il considerevole e qualificante
contributo dei medici dell’AIRM e dei membri del Comitato Internazionale dell'AIRP. A tutti coloro che hanno collaborato alla sua traduzione, revisione e pubblicazione con
notevole spirito di sacrificio, è rivolto l'apprezzamento e la riconoscenza delle nostre Associazioni, che riuniscono gli operatori attivi nei vari settori di interesse della radioprotezione
