ICARUS short base-line neutrino oscillation search at Fermilab
Get PDFICARUS liquid argon TPC detector was moved to Fermilab after a successful tree-years physics run at the INFN LNGS underground Laboratory. The detector is taking data exposed to Booster and NuMI off-axis neutrino beams to address, within the SBN experimental program, the longstanding puzzle of sterile neutrinos from the observed anomalies at accelerators, nuclear reactors and radioactive sources
The short-time approximation and its potential application to neutrino scattering
Get PDFThe short-time approximation (STA) has been developed to study nuclear responses to external electroweak probes and, to date, has been validated against electron scattering data; however, this technique is broadly applicable and
work is underway to extend it to study neutrino scattering from nuclei. These efforts are relevant to planned and on-going long-baseline neutrino oscillation experiments. In this contribution, we detail the theory behind the STA, discuss its use for electron scattering, and provide outlook for its use as a tool to study neutrino-nucleus scattering
Shell-model treatment of the β decay of 99Tc
Get PDFIn the present paper we treat the second-forbidden non-unique (2nd-nu) ground-state-to-ground-state β− decay 99Tc(9/2+) → 99Ru(5/2+), with a 100% branching ratio, within the framework of the nuclear shell model (NSM). The energy
spectrum of the electrons emitted in this β-decay transition (β-electron spectrum) is sensitive to the wave functions of the involved initial (9/2+) and final (5/2+) nuclear ground states through the many involved nuclear matrix elements (NME). The β-electron spectrum of this transition is potentially indicative of the effective value, geff A , of the weak axial coupling, gA, of crucial importance for extraction of information on beyond-the-standard-model physics from the results of the present and future rare-events experiments. We describe the β spectral shape of this decay by using a state-of-the-art β-decay formalism and compute the many involved NME using the well established NSM Hamiltonians jj45pnb and glekpn. We have found a strong dependence of the β spectral shape on the value of gA making it a good candidate for determination of the value of geff
A through comparison with the corresponding experimental β spectral shape. We have also found an interesting dependence of the β spectral shape on the value of the so-called small relativistic vector NME, sNME, used to match the computed half-life with the measured one
‘Ritorno a Vulci’. New tools for the study of the south-eastern necropolises
Get PDFThe project ‘Ritorno a Vulci’ focuses on specific sectors of the south-eastern necropolis of Vulci, where excavations have been conducted since the 1800s. One of the primary objectives of this project is to create a dedicated WebGIS that will generate and manage new topographical documentation of the area. This will serve as a collaborative digital research platform, making document consultation more accessible and contributing to their preservation. Another significant digital project is ‘Vulci nel Mondo’ (VNM), which is conceived as a Virtual Museum. The Authors illustrate this highly versatile tool as an online space to bring together a permanent collection on Vulci. The standard virtual tour model is built on two key aspects: navigation, providing access to the collections and other information on the museum’s website, and interaction, simulating a physical space with which visitors can engage
iDAI.field: developing software for the documentation of archaeological fieldwork
Get PDFThe German Archaeological Institute (Deutsches Archäologisches Institut, DAI) conducts a variety of different types of field research, each with its own unique documentation requirements: excavations, surveys and architectural surveys. The resulting differences are reflected in the workflows, the recording methods and the documentation. In addition, the DAI international work has to comply with the guidelines of the respective heritage agencies in the host countries. iDAI.field is the system for documenting archaeological fieldwork at the DAI. From the very beginning it was developed to meet these very different requirements. The development spanned several years, major versions and associated, far-reaching technology changes. The latest iteration of the application relies exclusively on open source technologies and is published on GitHub under the Apache License 2.0 in accordance with DAI-IT's open source policy. In order to open up the application to other interested researchers and/or developers, the focus of the last year has been the implementation of an extended configuration interface and the removal of dependencies from the DAI infrastructure. This article outlines the development history, introduces the currently available functionalities, and briefly discusses the data model, followed by an overview of the technologies used. It also describes the development into a real open source product and gives a short outlook on the future plans
Punto Zero, una nuova web application per la gestione e l'informatizzazione dei dati di archivio. Il caso di Ancona
Get PDFThe case of city of Ancona highlighted the lack of specific software for the management and digitization of the archaeological data stored in the archives of the Superintendence. The archives contain many heterogeneous data that can help to understand the history of the archaeological sites, from their discovery up to the information archived from the numerous research or rescue archaeology excavations that have taken place over time. The normalization of all the archival data within a single relational database associated with their specific geographical nature, thanks to an overall view and an in-depth review of the data, shed new light on both edited contexts and archaeological evidence that had not yet received an adequate study and that had not been entered into a system that considers nearby data. This software does not replace existing cataloging systems, such as SIGECweb, but it aims to support the cataloging activity using the same standard and at the same time allowing the Superintendence to use the data for the protection activity and for their study
IADI: an open Interactive Atlas of Digital Images for the journal «Archeologia e Calcolatori»
Get PDFScientific literature understanding benefits from visual resources, which is even more evident in the case of material cultural heritage. In recent years, journals and publishing platforms have been increasingly offering extensive access to publications via the contextual provision of visual media, such as images and 3D models. The diamond open access journal Archeologia e Calcolatori, founded in 1990, started publishing its articles in 2005 on its website and has always paid attention to giving proper value and presentation to visual contents related to publications. Indeed, it maintained an online image gallery displaying colour plates from volumes until coloured images started being embedded in the articles PDFs (since 2009). Then, in 2021, the journal added images and 3D models as resources together with publications and displayed them both as standalone content and in relation to articles. However, this later work did not include the previous thirty-year-long history of the journal, since it required close cooperation with authors. Thus a new dedicated web application was specifically developed to present a structured and visually appealing archive of about 4000 images. The paper illustrates this application, entitled A&CIADI (Interactive Atlas of Digital Images)
Testare sul campo la Least Cost Path Analysis: rifessioni intorno ai paesaggi dell'età del Bronzo della Sardegna centro-meridionale (Italia)
Get PDFFor about ten years this research team has been experimenting with techniques of spatial and visual perceptual analysis using GIS on the Nuragic landscapes (Middle and Late Bronze Age) of different areas of Southern Sardinia. Over time, various field campaigns have been developed on the monumental complexes built by the Nuragic communities. Towers, fortresses, villages, tombs of giants and sacred wells suggest a marked attention to the display of a message of power, strength and monumentality by the human group studied. An aspect often emphasized by these researches is the relationship of monuments with mobility and with the routes and strategic points of the territory, often verified through matches of different Least Coast Path Analyses (LCPA) that cross the territory by connecting different patterns of points. However, the real efficiency of the paths predicted by the GIS has never been directly tested on the ground. The paper presents the result of field analyses conducted by our group of archaeologists on the paths resulting from the GIS analysis in the Marmilla territories: travel times, energy expenditure and the real possibility of a path to actually cross a given territory are provided. Working with the LCPAs is still to be explored, however it remains a valid tool for territorial research, if an analysis unrelated to preconceptions and with a holistic evidence framework is carried out
The Spoil project. Assessing the rate of excavators’ accidental ceramic discard at the archaeological site of Siponto
Get PDFThis article aims to quantify the rate of accidental ceramic discard on the archaeological site of Siponto (Italy), where in 2022 the University of Bari and the University of Foggia conducted fieldwork and training for students at different education levels (BA to PhD). The goal was to identify and quantify factors leading to the accidental discard of ceramic sherds by excavators on the spoil heap. As a pilot project, a few variables have been considered to count the minimum number of individuals found after sieving soil composition and colour, weather conditions, time variables, sherds size, colour, and vessel part. Other categorical or presence/absence variables have also been considered. This enlightening investigation shows the bias in post-excavation quantification of ceramic finds. Results indicate that 30 of the fragments of pottery retrieved from the spoil heaps, used in this experiment, were diagnostic. The study also helps the educators on-site to identify the types of vessels that might be less clear for the students
Inducing the construction of formal axioms of Quantum Mechanics and fostering their comprehension by high school students: The effectiveness of a conceptual approach
Get PDFTaking as a paradigmatic example an educational reconstruction of Quantum Mechanics (QM), we discuss the approach and general research lines followed by the Physics Education Research Group of the Universities of Milan
and Rome. Our choice is prompted by the fact that through QM students can lay out the structure of a new grammar, which is necessary for the presentation of any quantum theory (in particular, Quantum Field Theory) in high school. In
particular, we discuss the results of a 15-hour pilot experimentation made in A.Y. 2021–2022, with high school students and teachers. The results obtained are highly
encouraging since they appear to indicate that the introduction of formal aspects of QM in Italian high school is possible with more than satisfying learning outcomes
