Regalità e simbologia del drago. La morte del duca Enrico e la devastazione della Borgogna nelle Storie di Rodolfo il Glabro
No full textLa ricerca si concentra su un’epifania draconica, contenuta nel secondo libro delle Storie di Rodolfo il Glabro, connessa alla morte di Enrico, duca di Borgogna, e alla successiva invasione della regione. L’autore analizza la presenza della bestia nella letteratura latina altomedievale e presenta il contesto socio-culturale della Borgogna, tra i secoli X e XI, per restituire un’interpretazione del drago come prefigurazione di futuri eventi nefasti, ovvero come genius loci e portentum regale.The paper focuses on a draconic epiphany, contained in the second book of Histories
of Rodulfus Glaber, connected to the death of Henry, duke of Burgundy, and the
following invasion of the region. The author analyses the beast’s presence in the early
medieval Latin literature and he presents the socio-cultural context of Burgundy,
between the X and XI centuries, to propose an interpretation of the dragon as
prefiguration of future negative events, that is as genius loci and royal portentum
Alle origini delle discipline aziendali: l’opera di G.A. Tagliente
No full textThe Contribution of G.A. Tagliente to the birth of business disciplines
The paper presents the work of a XVI century Italian Accounting author, G.A. Tagliente, giving a historiographic interpretation under a business economics point of view. The research is placed in a wider project of mapping Early Mod- ern Era contributions on Accounting, where contents, distinctly analyzed, are linked to their respective social and economic contexts. In the paper biograph- ical notes are placed in the Early XVI Century Venice and the whole literary production of the Author is presented before the proper accounting one. He was the second writer on double entry method, after Pacioli’s work. He pub- lished also books on mathematics for business, but his fortune is due mainly to the unique treatise on “simple entry book”, at those times very spread through the small and medium enterprises. Even if “minor” respect to the Great Pacioli, with him a cultural path began that would lead, finally, to the establish- ment of a new stream of thought: Accounting as we recognise it nowadays. In certain respects, furthermore, he underscored not still explored concern as- pects like family’s administration, extraordinary events, fixed assets and other peculiar issues
Synthetic Post-Contrast Imaging through Artificial Intelligence: Clinical Applications of Virtual and Augmented Contrast Media
No full textContrast media are widely diffused in biomedical imaging, due to their relevance in the diagnosis of numerous disorders. However, the risk of adverse reactions, the concern of potential damage to sensitive organs, and the recently described brain deposition of gadolinium salts, limit the use of contrast media in clinical practice. In recent years, the application of artificial intelligence (AI) techniques to biomedical imaging has led to the development of ‘virtual’ and ‘augmented’ contrasts. The idea behind these applications is to generate synthetic post-contrast images through AI computational modeling starting from the information available on other images acquired during the same scan. In these AI models, non-contrast images (virtual contrast) or low-dose post-contrast images (augmented contrast) are used as input data to generate synthetic post-contrast images, which are often undistinguishable from the native ones. In this review, we discuss the most recent advances of AI applications to biomedical imaging relative to synthetic contrast media

Addressing backing techniques through high-magnification microscopy and quantitative analyses
No full textThe application of backing techniques is a central element in the manufacturing process of Upper Palaeolithic and Mesolithic lithic projectile implements (e.g., backed points, backed bladelets, backed and truncated bladelets, geometrics, etc.). In recent years, different studies based on a low magnification analysis have been developed to provide a more accurate and comprehensive understanding of these techniques. Within this general framework, to improve the reliability of backing techniques recognition, this paper explores the application of new methodologies including a high magnification microscopy and a quantitative analysis. The former permitted
the observation of several microscopic traces (e.g., polishes and striations) yielding important information concerning the nature of the used retoucher (mineral vs. organic). The latter allowed evaluating the variability of several retouch scars features (angles, depth and size) and their statistical significance to distinguish backing
techniques. Both methods were then applied to an archaeological sample of projectile implements from Riparo Tagliente (VR, Italy), providing valuable insights regarding backing techniques used by Late Epigravettian hunter-gatherer groups

Carne, semi e frutti: gli animali e le piante come fonte alimentare nel Paleolitico del territorio Veronese
No full textLe Prealpi Venete, in particolare i Monti Lessini, conservano numerose testimonianze di occupazione umana dal Paleolitico, grazie alla presenza di ripari naturali e di risorse minerarie di alta qualità. L’approvvigionamento di materie prime litiche fornisce dati sui movimenti dei gruppi paleolitici. I ritrovamenti del Paleolitico Inferiore sono numerosi ma di difficile datazione, basata su caratteristiche tecniche e sul grado di patinatura. Tra i siti principali vi sono le cave di Quinzano, importanti anche per i resti faunistici. Grotta di Fumane, Grotta della Ghiacciaia e Riparo Tagliente conservano archivi stratigrafici fondamentali per lo studio delle occupazioni preistoriche. I siti all’aperto, meno documentati, si trovano nel settore centro-occidentale dei Lessini e sul Monte Baldo. Le ricerche, avviate dal Museo di Storia Naturale di Verona e proseguite dall’Università di Ferrara, continuano a fornire nuovi dati sulle strategie di sussistenza preistoriche. Nel 2017, il sito di Vajo Salsone ha rivelato numerosi manufatti litici e resti faunistici. Lo studio comparativo di questi siti ha permesso di ricostruire le strategie di mobilità e sussistenza dei Neanderthal, degli uomini moderni e degli ultimi cacciatori-raccoglitori epigravettiani

3D CT-Inclusive Deep-Learning Model to Predict Mortality, ICU Admittance, and Intubation in COVID-19 Patients
No full textABSTRACT: Chest CT is a useful initial exam in patients with coronavirus disease 2019 (COVID-19) for assessing lung damage. AI-powered predictive models could be useful to better allocate resources in the midst of the pandemic. Our aim was to build a deep-learning (DL) model for COVID-19 outcome prediction inclusive of 3D chest CT images acquired at hospital admission. This retrospective multicentric study included 1051 patients (mean age 69, SD = 15) who presented to the emergency department of three different institutions between 20th March 2020 and 20th January 2021 with COVID-19 confirmed by real-time reverse transcriptase polymerase chain reaction (RT-PCR). Chest CT at hospital admission were evaluated by a 3D residual neural network algorithm. Training, internal validation, and external validation groups included 608, 153, and 290 patients, respectively. Images, clinical, and laboratory data were fed into different customizations of a dense neural network to choose the best performing architecture for the prediction of mortality, intubation, and intensive care unit (ICU) admission. The AI model tested on CT and clinical features displayed accuracy, sensitivity, specificity, and ROC-AUC, respectively, of 91.7%, 90.5%, 92.4%, and 95% for the prediction of patient’s mortality; 91.3%, 91.5%, 89.8%, and 95% for intubation; and 89.6%, 90.2%, 86.5%, and 94% for ICU admission (internal validation) in the testing cohort. The performance was lower in the validation cohort for mortality (71.7%, 55.6%, 74.8%, 72%), intubation (72.6%, 74.7%, 45.7%, 64%), and ICU admission (74.7%, 77%, 46%, 70%) prediction. The addition of the available laboratory data led to an increase in sensitivity for patient’s mortality (66%) and specificity for intubation and ICU admission (50%, 52%, respectively), while the other metrics maintained similar performance results. We present a deep-learning model to predict mortality, ICU admittance, and intubation in COVID-19 patients. KEY POINTS: • 3D CT-based deep learning model predicted the internal validation set with high accuracy, sensibility and specificity (> 90%) mortality, ICU admittance, and intubation in COVID-19 patients. • The model slightly increased prediction results when laboratory data were added to the analysis, despite data imbalance. However, the model accuracy dropped when CT images were not considered in the analysis, implying an important role of CT in predicting outcomes.
