ODINet un framework innovativo per l\u27accesso e la diffusione on-line di dati strutturati ed eterogenei
Get PDFODINet is a research and development project, approved as part of the Regional Operational Programme through the European Regional Development Fund 2007-2013. The project involves the construction of a semantic search engine prototype able to catalog the data in a ontological graph, to extract the most relevant information depending on user requests and return them in a highly usable way. The application domain concerns the social, economic and health, in order to cover most of the data held by public bodies in the national context. The focus of this report is in the first place the description of the semantic components of the platform, emphasizing how the ontologies have been used to build an index in the form of graph. We also present a description of our semantic searches and finally an analysis of the results obtained in the final stage of the ODINEt prototype testing

Towards the creation of integrated authority files in the domain of science and technology: an Italian use case
Get PDFOver the years, different organizations have developed and shared a number of authority files with normalized personal names (e.g. Virtual International Authority File - VIAF),inviting others to use these sources as a ?common language? and contributing to improved interoperability among resources/systems. Nevertheless, numerous data providers continue to create and to take advantage of locally developed authority lists mined from the resources managed in local repositories and not aligned with external trustworthy sources. These authority lists often remain locked in local databases inhibiting sharing, re-use and interoperability of their data. This paper aims to present a use case on the creation of integrated and dynamic local authority files referring to the personal names of important Italian scientists and academics to be used within a federate Digital Library about Science and Technology. Terminology extraction techniques have been applied to a corpus of 400 documents in the National Centre of Electronic Calculation\u27s archive. This resulted in an authority list of 700 personal names that was further aligned with VIAF and other authorities, such as Library of Congress Classification, via a manual mapping process, thus ensuring its interoperability and retrieval of bibliographic data and topics for each name. Future work will include the creation of CNUCE subject headings based on the list of keywords extracted from the CNUCE corpus and mapping to the Nuovo Soggettario and to LCSH
An Overview of the Tourpedia Linked Dataset with a Focus on Relations Discovery among Places
Get PDFTourpedia (http://tour-pedia.org) is an open initiative which contains a linked dataset of tourism places, i.e. accommodations, attractions, points of interest (POIs) and restau- rants. Tourpedia extracts and integrates information about places from four different social social media: Facebook, Foursquare, Google Places and Booking.com. The resulting knowledge base currently consists of more than 6M RDF triples and describes almost 500.000 places, each of which is identified by a globally unique identifier, which can be dereferenced over the Web into a RDF description. This paper gives an overview of the Tourpedia knowledge base and illustrates how new relations are discovered among places through Named Entity Recognition (NER) tools.?
Comprehensive Approach to Increase Cyber Security and Resilience
Get PDFIn this paper the initial results of the European project CAMINO in terms of the realistic roadmap to counter cyber crime and cyber terrorism are presented. The roadmap is built in accordance to so called CAMINO THOR approach, where cyber security is perceived comprehensively in 4 dimensions: Technical, Human, Organizational, and Regulatory
Epilepsy with auditory features: a heterogeneous clinico-molecular disease
Get PDFObjective: To identify novel genes implicated in epilepsy with auditory features (EAF) in phenotypically heterogeneous families with unknown molecular basis.Methods: We identified 15 probands with EAF in whom an LGI1 mutation had been excluded. We performed electroclinical phenotyping on all probands and available affected relatives. We used whole-exome sequencing (WES) in 20 individuals with EAF (including all the probands and 5 relatives) to identify single nucleotide variants, small insertions/deletions, and copy number variants.Results: WES revealed likely pathogenic variants in genes that had not been previously associated with EAF: a CNTNAP2 intragenic deletion, 2 truncating mutations of DEPDC5, and a missense SCN1A change.Conclusions: EAF is a clinically and molecularly heterogeneous disease. The association of EAF with CNTNAP2, DEPDC5, and SCN1A mutations widens the phenotypic spectrum related to these genes. CNTNAP2 encodes CASPR2, a member of the voltage-gated potassium channel complex in which LGI1 plays a role. The finding of a CNTNAP2 deletion emphasizes the importance of this complex in EAF and shows biological convergence
Growth response, plasma metabolites and intestinal brush border enzyme activity of sea bass fed diets including a blend of two marine microalgae
No full textMicroalgae have attracted increasing attention as animal feed supplements since they are natural sources of bioactive compounds which give them nutraceutical properties in addition to their basic nutritional value. More recently, dry microalgae biomass have also been proposed as raw materials in partial substitution for fish meal and oil in aquafeeds. The aim of this study was to evaluate the effects of including a blend of dried marine microalgae in low fish meal/fish oil diets on growth performance, levels of plasma metabolites and activity of brush border intestinal enzymes in adult European sea bass (Dicentrarchus labrax, L.). Two test diets (A1 and A2) were prepared by including a blend of Isochrysis galbana and Tetraselmis suecica dried biomass in a 2:1 w:w ratio to replace 15 and 45% fish meal protein and 10 and 30% fish lipid of a control diet (C) with a 50:50 fish to vegetable-protein-lipid ratio. One hundred eight fish (mean body weight 204?12.7 g) were randomly divided among 9 groups kept in a marine recirculating tank system ensuring nearly optimal water condition to sea bass (temperature 21?C, salinity 28?). Fish were fed the test diets to visual satiety over 15 weeks according to a randomized design with 3 replicates per dietary treatment. At the end of the trial, final biomass, specific growth rate (SGR) and feed conversion ratio (FCR) were calculated per group and 6 fish per dietary treatment were sacrificed and immediately subjected to blood and intestine sampling for further analysis of plasma metabolite levels (glucose, cholesterol, triglyceride, total proteins and albumin levels) and activity of mucosal brush border enzymes in different sections. No diet-induced effects were noted in the final individual live weight, 420?14.5g, SGR, 0.68?0.003 and FCR, 1.7?0.11. Amongst plasma metabolites, only cholesterol and total proteins were affected by dietary treatments resulting in reduced levels only in fish given the diet highest in microalgae relative to controls (347.2 vs. 276.6 mg/dL and 5.90 vs. 5.37 mg/dl; respectively, P<0.05). The activity of the intestinal mucosal enzymes varied according to the different intestinal tracts but did not show major diet-dependent changes. This study suggests that a blend of dried marine microalgae biomass could further reduce reliance on fish meal and fish oil in practical diets for adult sea bass without adversely affecting growth response and digestive-absorptive functions

Experimental Analysis of the Water Entry of a Plate at High Horizontal Speed
No full textThe water entry of plates at high horizontal speed is investigated experimentally in this work. The motivation for this study stems from the aeronautical field and in particular from aircraft ditching analysis with the objective of developing more accurate and reliable simulation tools for aircraft manufacturers to be used within design and certification. In order to build an experimental database to support the validation of the methods, a new experimental facility has been designed and installed at CNR-INSEAN. In this paper some of the results in terms of pressures, strains and forces are presented and discussed for two test conditions. Particular attention is paid to the assessment of the dispersion of the data and the repeatability of the experiments. Some of the key physical aspects of the phenomenon are also discussed
