Wikidata e SBN : un bilancio di due anni di lavoro (2023-2025)
Full text linkL’articolo presenta i presupposti teorici e la ricostruzione dell’intensa attività di controllo bibliografico, correzione e riconciliazione, che hanno consentito che il legame tra le Voci di autorità di SBN e gli elementi di Wikidata si consolidasse progressivamente, in particolare nel corso degli ultimi due anni. L’articolo illustra e analizza in dettaglio gli interventi più recenti, effettuati grazie alla collaborazione tra l’ICCU e la comunità di Wikidata. Sulla base dell’esperienza maturata, vengono proposte alcune strategie fondamentali per rafforzare ulteriormente la presenza delle entità culturali italiane nel web semantico e nella rete dei dati collegati (“Linked Data”). Si suggerisce di perseguire questo obiettivo lungo due direttrici principali: offrire percorsi di accesso affidabili da e verso SBN, favorendo l’interoperabilità tra sistemi informativi, e promuovere la conoscenza delle migliori pratiche di metadatazione all’interno delle pratiche di catalogazione ordinaria.The article presents the theoretical foundations and the reconstruction of the intensive bibliographic control, correction, and reconciliation activities that have progressively strengthened the link between SBN authority records and Wikidata entities, particularly over the past two years. It provides a detailed account and analysis of the most recent interventions carried out through the collaboration between ICCU and the Wikidata community. Building on this experience, the paper proposes a set of key strategies to further enhance the representation of Italian cultural entities within the Semantic Web and the network of Linked Data. Two main directions are suggested to pursue this goal: developing reliable pathways of access to and from SBN in order to foster interoperability among information systems, and promoting awareness of best practices in metadata creation within ordinary cataloguing workflows
Stretching of polymers and turbulence: Fokker Planck equation, special stochastic scaling limit and stationary law
No full textThe aim of this work is understanding the stretching mechanism of stochastic models of turbulence
acting on a simple model of dilute polymers. We consider a turbulent model that is white noise in time
and activates frequencies in a shell N ≤ |k| ≤ 2N and investigate the scaling limit as N → ∞, under
suitable intensity assumption, such that the stretching term has a finite limit covariance. The polymer density
equation, initially an SPDE, converges weakly to a limit deterministic equation with a new term. Stationary
solutions can be computed and show power law decay in the polymer length
Interpretative Notes on Valerius Flaccus, Argonautica 5.379, 380, 416-432. With an Appendix on Ovid, Metamorphoses 2.398-400
No full textThis article offers some interpretative insights into the fifth book of Valerius Flaccus’ Argonautica. In the first part, a Virgilian allusion is highlighted (5.379 ∼ A. 4.511), which contributes to the tragic irony that characterizes Jason’s speech to Medea during their first meeting. The second part suggests a reaction by Valerius to contemporary Virgilian criticism, specifically that of Marcus Valerius Probus. In part three, some considerations are made on the relationship between the “historical” scenes carved on the door of the temple of Sol (5.416-432) and the Argonautic saga, linking the pharaoh Sesostris to Jason, the nymph Aea to Medea, and the death of Phaethon to that of Apsyrtus. Finally, a brief appendix (§4) reaffirms the authenticity of Ov. Met. 2.398-400 in light of its relationship to the Homeric model (Il. 19.399-403) and Valerius’ later allusion (5.432)
Corpus di acquasantiere a fusto e da parete: dalle origini alla fine del Quattrocento (Italia centro-settentrionale)
No full textThe research project concerns the study and cataloguing of freestanding and wall-mounted holy water fonts preserved in central
and northern Italy, roughly between the Marche region and the Alps, dating from the 12th to the 15th centuries. The catalogue of
works, which includes 273 holy water fonts, is accompanied by a first volume of introductory essays. The initial chapter
undertakes an examination of the origins, earliest Christian uses, and nature of holy water. In order to facilitate an understanding
of the uncertain transition from vernacular, mobile containers to monumental, stone holy water fonts, the textual sources range
from early Christianity to the 15th century. The second chapter is concerned with the morphology of the components of the
furnishings (basin, base, stem, and any accoutrements) and the materials needed for their fabrication, ranging from marble to
bronze, with due consideration for the layer of polychromy that would have constituted the finish. The final paragraph of this
chapter is dedicated to the practice of reusing and repurposing Etruscan, Roman, and medieval artefacts in the form of holy water fonts. The third chapter aims to identify the iconography and employed in the embellishment of holy water fonts. This
encompasses the initial proposals for the original ornamentation, an examination of the human and zoomorphic protomes that
frequently adorn the rim of the basins, the hagiographic narrative and the presence of patron saints carved around them, and the
iconographic manifestations that, through the juxtaposition of diverse negative and positive figurations, establish a semiotic
network within the stone architecture. This network is susceptible to iconological interpretations. The final chapter of this study
focuses on the opportunities and dynamics of commissioning the furnishings. It considers the epigraphic elements that enliven
some parts of the holy water fonts and the heraldic arms. These elements, along with inscriptions and signatures, accompany
their placement in the liturgical space and the proportionate ostentation of the financing family. The compilation of the work is the
culmination of three years of on-site inspections and autopsy analyses of each individual catalogued work, which was
photographed from scratch by the author
Simultaneous Probe of the Charm and Bottom Quark Yukawa Couplings Using t ̄tH Events
No full textA search for the standard model Higgs boson decaying to a charm quark-antiquark pair, (Formula presented), produced in association with a top quark-antiquark pair ((Formula presented)) is presented. The search is performed with data from proton-proton collisions at (Formula presented), corresponding to an integrated luminosity of (Formula presented). Advanced machine learning techniques are employed for jet flavor identification and event classification. The Higgs boson decay to a bottom quark-antiquark pair is measured simultaneously and the observed (Formula presented) event rate relative to the standard model expectation is (Formula presented). The observed (expected) upper limit on the product of production cross section and branching fraction (Formula presented) is 0.11 (0.13) pb at 95% confidence level, corresponding to 7.8 (8.7) times the standard model prediction. When combined with the previous search for (Formula presented) via associated production with a (Formula presented) or (Formula presented) boson, the observed (expected) 95% confidence interval on the Higgs-charm Yukawa coupling modifier, (Formula presented), is (Formula presented) (2.7), the most stringent constraint to date

No full textFirst Exclusive Reconstruction of the B * + , B * 0 , and B s * 0 Mesons and Precise Measurement of Their Masses
No full textUsing proton-proton collision data collected by the CMS experiment at (Formula presented) in 2016-2018, corresponding to an integrated luminosity of (Formula presented), the first full reconstruction of the three vector (Formula presented) meson states, (Formula presented), (Formula presented), and (Formula presented), is performed. The mass differences between the excited mesons and their corresponding ground states are measured to be (Formula presented), (Formula presented), and (Formula presented), where the first uncertainties are statistical and the second are systematic. These results improve on the precision of previous measurements by an order of magnitude
