Direct search for the Higgs boson to charm coupling at ATLAS
No full textA direct search for the Standard Model Higgs boson decays to a pair of charm quarks is presented. This analysis uses the full LHC Run 2 dataset collected with the ATLAS detector, corresponding to an integrated luminosity of 139 inverse femtobarns of proton-proton collisions at a centre-of-mass energy of 13 TeV. An extrapolation of this search to the HL-LHC conditions (centre-of-mass energy of 14 TeV, integrated luminosity of 3000 inverse femtobarns) is also presented.
The production of the Higgs boson in association with a W or Z boson decaying leptonically is measured. Flavour jet tagging algorithms are used to identify the signature of the Higgs boson decay to charm quarks, while reducing contamination from Higgs boson decays to bottom quarks. This search improves the constraint on the cross section times branching fraction for a Standard Model Higgs boson
previously presented by ATLAS, using an integrated luminosity of 36 inverse femtobarns of proton-proton collisions at the same centre-of-mass energy. A constraint
on the charm Yukawa coupling modifier from Higgs boson to charm quark decays is also set. The HL-LHC extrapolation of this search further improved the expected constraints
Children of imprisoned parents: an Italian and European analysis
Get PDFThe article examines the situation of children of parents in conflict with the law from a victimological and socio-criminological perspective, considering them as secondary victims of their parents’ offences. A comparative analysis was conducted on the conditions of these minors in Italy and Europe, investigating the legal framework, the maternity management, the possible presence of children residing in prison, and providing some examples of organisations and associations working to safeguard the well-being of these children. Particular attention was dedicated to the role of the school as protective factor for children experiencing parental imprisonment. Moreover, a questionnaire was developed which examined the awareness level of teachers in the Italian school system to understand whether these professionals were aware of the presence of underage
students with at least one imprisoned parent in their classrooms
L’intelligenza artificiale applicata al patrimonio culturale. Una innovazione tecnologica per la conservazione e la valorizzazione del patrimomio culturale
Get PDFArtificial intelligence (AI) represents a promising frontier for cultural heritage, offering new perspectives for conservation, cataloguing, research and valorisation.
AI can allow us to preserve and pass on our cultural roots to future generations. However, a "balanced" approach is needed,
in which technological innovation is embraced while preserving the integrity and value of the works of art and of history itself. With careful management, artificial intelligence can become a valuable tool for preserving and enhancing our cultural heritage for future generations. What are the benefits, challenges and future developments of AI in the context of cultural heritage
Female delinquency in Spain and its treatment
Get PDFRecorded female crime is less than 10% in Spain, as is the case in other European countries, however, women continue to be studied more as victims than as perpetrators. The purpose of this article is to show a general view of the phenomenon of female delinquency in Spain in the last decade, showing its characteristics, prevalence, profiles, and the treatment in prison of a population that represents a minority within penitentiary institutions. To do this, a mixed methodology is used, resorting to official statistics and data regarding the phenomenon presented, but also to studies that analyse this subject. In the same way, female prison population is compared with the data concerning the male population, pointing out similarities and differences both quantitatively and qualitatively. As main conclusions, it can be highlighted how the treatment of female offenders continues to present marked sexist biases and lacks a gender perspective in its treatment
Il bisogno affettivo e l’inganno dei social: i presupposti e le pratiche del Romance Scam
Get PDFNella società odierna, l’amore diviene scappatoia dalla solitudine ed oggetto di relazioni digitali che, spesso, sembrano sostituire i rapporti “umani” in una dinamica sentimentale già molto complessa, ma resa ancora più articolata dall’esperienza del SARS-CoV-2. Tale “sensibilità emozionale” (Condorelli, 2021) si inserisce, infatti, nel più ampio, attuale e rinnovato dibattito sul legame affettivo di tipo amoroso che, dallo spazio individuale dalle caratteristiche tangibili, si palesa sul palcoscenico dell’estimità online (Tisseron, 2011; Stanton et al., 2016). Invero, secondo la Polizia Postale nel 2021, in Italia, si è registrato +118% di truffe sentimentali (Polizia Postale, 2022). Fra questi pericoli, in particolare, il Romance Scam (Love Scam o anche definito sweetheart swindles) pratica criminale nella quale un utente viene adescato da truffatori (scammers) che usano un’identità falsa o rubata sui social network al fine di estorcere, truffare o ricattare la vittima che crede di vivere una vera relazione amorosa (;Whitty, 2015; 2018; Carter, 2021; Cassandra, Lee, 2022; Suleman et al., 2023). Il saggio vuole riflettere, quindi, sulla dinamica online da un punto di vista socio-criminologico, partendo dalle teorizzazioni sul tema per arrivare alle più recenti ed attuali implicazioni del fenomeno con particolare attenzione alle dinamiche emotive sottese ed emergenti
La compensazione statale delle vittime di reato negli stati membri dell’UE: uno studio comparativo
Get PDFLa compensazione statale delle vittime di reato potrebbe essere definita come un istituto giovane ma problematico. Nel corso della sua relativamente breve storia, che prende le mosse dalle origini della vittimologia nel corso del secondo dopoguerra, essa ha sollevato un dibattito acceso, ricco di considerazioni riguardanti la figura della vittima di reato, i fondamenti dell’istituto stesso, ma anche le sue criticità. Dopo aver riportato sinteticamente questi aspetti e i principali passaggi evolutivi dell’istituto compensatorio, specialmente nel contesto dell’Unione Europea, il presente articolo riporterà i risultati di una ricerca a carattere comparativo che ha inteso raccogliere dati sul livello di implementazione della compensazione nei 27 Stati Membri dell’Unione, ricorrendo a fonti di carattere legislativo, ricerche svolte con metodologie uniformi negli Stati Membri e informazioni supplementari reperite attraverso altri canali. Tali risultati sono stati poi confrontati criticamente intorno ad alcuni nodi tematici particolarmente pregnanti al fine di individuare linee di tendenza e di divergenza nelle soluzioni di volta in volta proposte per risolvere le questioni più problematiche. Nella conclusione, l’autore svolge una breve riflessione sul possibile futuro della compensazione e sull’opportunità del suo assorbimento nel più ampio concetto di riparazion
Opening the path to hard X-/soft gamma-ray focussing: The ASTENA-pathfinder mission
Get PDFHard X-/soft gamma-ray astronomy is a crucial field for transient, nuclear and multimessenger astrophysics. However, the spatial localization, imaging capabilities and sensitivity of the measurements are strongly limited for the energy range >70keV. To overcome these limitations, we have proposed a mission concept, ASTENA, submitted to ESA for its program “Voyage 2050”. We will report on a pathfinder of ASTENA, that we intend to propose to ASI as an Italian mission with international participation. It will be based on one of the two instruments aboard ASTENA: a Laue lens with 20m focal length, able to focus hard X-rays in the 50–700keV passband into a 3-d position sensitive focal plane spectrometer. The combination of the focussing properties of the lens and of the localization properties of the detector will provide unparalleled imaging and spectroscopic capabilities, thus enabling studies of phenomena such as gamma-ray bursts afterglows, supernova explosions, positron annihilation lines and many more
A deep-learning–based method to spectrally separate overlapping fluorophores based on their fluorescence lifetime
Get PDFThe simultaneous labelling and imaging of different bio-molecules are required to understand the relationships between the various sub-cellular components and macro-molecular complexes constituting a cell. In fluorescence mi
croscopy, a careful selection of fluorophores is required to prevent spectral overlap, which limits the number and types of fluorophores that can be simultaneously used. This limitation can be overcome with the fluorescence lifetime, able to separate the fluorescence signal. In this study, the authors used deep learning to separate two fluorophores based on their fluorescence lifetime, taking advantage of non-linear spatial-temporal information. The training was carried out on synthetic images, and the results were evaluated on test synthetic images
