Anxiety and Suicidality in a Hospitalized Patient with COVID-19 Infection
Get PDFWe describe a case of a young man admitted to due to mild COVID-19 infection. During his hospitalization in an isolation ward, he had no respiratory distress or fever but developed symptoms consistent with anxiety and insomnia. Despite the appropriate supportive intervention, on hospital day 7, he attempted suicide by jumping from the third-floor ward. The patient was urgently operated and transferred to level I trauma center under strict isolation. Our findings emphasize the importance of mental health aspects during the treatment of patients during the COVID-19 pandemic
Covid-19: la decisione clinica in condizioni di carenza di risorse e il criterio del “triage in emergenza pandemica”
Get PDFDa diversi mesi il nostro Paese si trova a dover fronteggiare una minaccia senza precedenti per la salute e
la vita dei cittadini, provocata dal rapido e crescente contagio del virus Sars-CoV-2. Una minaccia tanto più
difficile da contrastare poiché è stata sottovalutata l’allerta sul rischio di pandemie globali lanciata da organismi internazionali, con conseguenti ritardi nella preparazione a fronteggiare le emergenze sanitarie1. Il sistema sanitario2 è stato sottoposto a una pressione straordinaria e ha dovuto velocemente riorganizzarsi e ristrutturarsi, per cercare di individuare ed isolare i soggetti fonte di contagio e, nei casi più gravi, per poter curare gli ammalati da Covid-19 in reparti ospedalieri di terapia intensiva e subintensiva, spesso allestiti in pochissimo tempo. Nel contesto della salute pubblica, l’evento pandemico provocato dal Covid-19 ha assunto aspetti di particolare drammaticità

Get PDFA new computational method to quantify morphological standardization and variation within ceramic assemblages
Get PDFAnalysis of ceramic standardization and variation provides a powerful tool for evaluating the scale, organization, and technological practices behind pre-modern production and for gauging the coordination and complexity of past economic systems. The selection of formal attributes to allow effective measurement and comparison of complex shapes, though, presents a crucial challenge to systematic study. Alongside fabric composition and surface treatment, consistent linear dimensions offer helpful metrics for assessing standardized production. More difficult to measure, though, are the many finely graduated variations in shape that can reflect how these processes were implemented and the limits to large-scale serial productions like those of the ancient Mediterranean world. We offer here a new method and computational pipeline, developed using open-source libraries, to quantify morphological similarities and differences among ceramics. Grounded in point cloud comparison, our method enables comprehensive 3D characterization of geometries down to the pixel level and leverages state-of-the-art machine learning algorithms and high-speed data structures for efficiency and scalability across large assemblages. Case studies of transport amphoras from two late antique shipwrecks off the coast of southwest Turkey demonstrate the robustness of the methodology and pipeline. Together, they provide an analytically rigorous and flexible approach to quantifying formal variation within a dataset. The first results suggest strategies for controlling the capacities of these transport jars within late ancient systems of production, but the method should also prove useful in formal analysis of artifacts of other forms and contexts
NArCoS project for nuclear physics and applications
No full textWith the advent of new facilities for radioactive ion beams it is necessary to develop neutron detection systems integrated with charged-particle ones. The integration of the neutron signal, especially in the case of neutron-rich beams, becomes a mandatory requirement in order to study the property of the nuclear matter in extreme conditions. For this reason, new detectors using new materials have to be built. NArCoS (Neutron ARray for COrrelation Studies) is a project aimed at the design of a new detector featuring both good energy and angular resolution sensitive to neutrons and charged particles with the same detection cell. We present in this contribution new results on the estimation of the detection efficiency
and of the cross-talk performed via GEANT4 simulations. In addition we compare through experimental measurements a module with the EJ276 green shifted scintillator coupled with a silicon photodiode with respect to one featuring an EJ276 (standard version) and a silicon photomultiplier
ToF in heavy ion reaction: CHIMERA detector and ISODEC experiment
No full textThe CHIMERA detector is a powerful array to study heavy ions collisions in a large dynamical range from low to Fermi energy. A summary of its characteristics and the applied identification methods is reported. In particular, we highlight the relevance of the ToF technique in the reaction products identification process. Among the many experiments realized by using the CHIMERA detector since 2000, in this work we present the results of the ISODEC experiment, a recent study on the neutron-poor 78Kr+40Ca and the neutron-rich 86Kr+48Ca systems, at 10 AMeV. For these reactions, we analyzed the fusion-evaporation and fission-like processes, and their dependence on the isospin, that is expected to play a crucial role in the onset of these processes
Multi-boson electroweak physics at CMS
No full textThe precision measurement of multi-boson processes at the Large Hadron Collider is a fundamental test of the consistency of the Standard Model and can hint at effects of new physics. In this note, the most relevant results obtained in multi-boson processes by the CMS experiment at a centre of mass energy of 13 TeV are presented with particular focus on the results interpretation in the framework of Effective Field Theories
Recent progress in solar modulation modeling in light of new cosmic-ray data from AMS-02
No full textAfter entering into the heliosphere, Galactic cosmic rays (CRs) are influenced by magnetic turbulence and solar wind disturbances, which cause the so-called “solar modulation” effect. Understanding the relationship between the Sun’s variability and the CR modulation effect is essential for the investigation of the physical processes of CR transport in the heliosphere, as well as for the establishment of predictive models of CR radiation in the interplanetary space. In the study of this phenomenon, the key ingredients are the knowledge of the CR interstellar spectrum and the detailed understanding of how this spectrum is modulated inside the heliosphere. For this purpose, we present a newly developed model of solar modulation where the key parameters describing the CR physics processes are constrained by the new monthly-resolved data of AMS-02. The comparison between model calculations and CR data is presented at various energies and epochs of the solar cycle. Calculations of the propagation times of CRs, their energy losses, and their trajectories through the heliosphere are also presented and discussed
Expected performance of the FOOT experiment
No full textThe main objective of the FOOT (FragmentatiOn of Target) experiment is to measure the double differential cross-sections with respect to the kinetic energy and the angle of emission of fragments produced in nuclear interactions with an accuracy of 5%. Measurements will use the inverse kinematics approach to study the interaction of heavy ions with proton-rich targets and will be performed in two
energy regions, one up to 400 MeV/u, to assess the effects of nuclear fragmentation in hadrontherapy treatment with proton beams, and up to 700 MeV/u, to improve the knowledge of the fragmentation of ions on nuclei to help with the design of space vehicles shielding
Somnia. Il sogno dall'antichità all'età moderna
Get PDFIl volume ripercorre momenti decisivi della riflessione sul sogno dall’antichità e dalla tarda antichità all’età moderna. A partire dalla sintesi storico-critica presentata da Tullio Gregory, la ricerca sul somnium affronta, con gli interventi di Francesco Fronterotta e Francesca Alesse, il pensiero di Platone e di Aristotele, qui restituiti lungo due assi principali della tradizione antica, ai quali si aggiungono, con i saggi di Francesca Calabi e Domenico Devoti, fasi fondamentali dell’elaborazione di Filone di Alessandria e della tradizione ebraica e neotestamentaria. Dal versante della ripresa di temi neoplatonici e teurgici muove poi il contributo di Luciano Albanese su Giuliano il Teurgo, cui segue il saggio di Gaetano Lettieri su Agostino quale autore decisivo per la ridefinizione della concezione del sogno. È un quadro complesso e ricco restituito, a partire dalla fase rinascimentale e primo moderna, nel testo di Claudio Buccolini e, in merito al lessico cartesiano, nel contributo di Giulia Belgioioso. Il testo di Anna Lisa Schino affronta il tema dei sogni profetici fra La Mothe Le Vayer e Hobbes, mentre proprio all’autore del Leviathan e al rapporto fra sogni e politica dell’immaginazione è dedicato il contributo di Daniel Garber. Pina Totaro indaga i contesti della concezione del sogno e della conoscenza in Spinoza, mentre il saggio di Isabelle Olivo-Pendron e Gilles Olivo considera, in una modernità compresa nell’arco temporale che va da Montaigne a Rousseau, non precisamente il sogno ma la “rêverie”
