La “Donna di Ostuni”, a case of eclampsia 28,000 years ago?
2017
La "Donna di Ostuni", the Lady from Ostuni (fortified medieval city, on the southern Italian Adriatic coast) is the skeleton of "the human most ancient mother" ever found by paleoanthropologists, grave dated of 28,000 years BP. It concerns a 20-years-old woman buried with her baby in her womb estimated at 8 months gestation. To date, the cause of the maternal-fetal deaths is qualified of unknown origin. We propose that eclampsia may be a possible explanation for these deaths (mother and baby together). Eclampsia (convulsions), the curse of human births (non-existent in other mammals), has been described since writings has existed 5000 years ago in all civilisations. This plausible descripti…
Gesture recognition using low-cost devices: Techniques, applications, perspectives
2016
Negli ultimi anni abbiamo assistito ad una grande diffusione dei cosiddetti “Kinect-like devices”, ovvero dispositivi basati su un insieme di sensori a basso costo, che consentono di ottenere un’immagine di profondità della scena ripresa. L’alta accessibilità di questi dispositivi, principalmente in termini di costi, ne ha facilitato la diffusione nell’ambito del riconoscimento dei gesti in numerose applicazioni, sia commerciali che di ricerca. In questo articolo saranno inizialmente illustrati i principi generali su cui si fondano le principali tecniche utilizzate per riconoscere i gesti, sfruttando i dati ottenibili dai dispositivi “Kinect-like”. Successivamente, saranno presentati alcuni…
Vintage violence. La strana violenza del cinema di Losey
2015
Los textos sobre la violencia tienden a dar por sentado este concepto. En este artículo se intentará esbozar una definición semiótica a través de una breve relectura de algunos clásicos y de algunas entradas de vocabulario, para sugerir una caracterización de la violencia como dispositivo semiótico: una articulación de dos figuras diferentes de agresión («laceración»/«constricción») contra un umbral convencional. Esta hipótesis se desarrolla en el análisis de las películas de Joseph Losey, donde la violencia aparece de muchas formas, pero nunca llega a ser (con raras excepciones) totalmente explícita o espectacular. El artículo reconsidera el análisis de Gilles Deleuze en L’Image-Mouvement,…
Anglicisms and Italian Equivalents in the Era of Covid-19: A Corpus-Based Study of Lockdown
2020
The whole globe has been going through an unprecedented historical moment since World War II. COVID-19, the disease against which we have all been trying to defend ourselves for several months now, has spread worldwide with a significant impact in all spheres of life. With the pandemic outburst and English the language of globalization, several Anglicisms have entered the lexicon of other languages, especially Italian, traditionally open to foreign words. COVID-19-related Anglicisms are used in Italian to such an extent that we can reasonably refer to them as the ‘language of pandemic’. The English words and expressions employed in Italian to refer to the current disease are numerous. Some …

A mobile game as a support tool for children with severe difficulties in reading and spelling
2020
We used a randomized controlled trial to investigate if a mobile game, GraphoLearn (GL), could effectively support the learning of first graders (N = 70), who have severe difficulties in reading and spelling. We studied the effects of two versions of the game: GL Reading, which focused on training letter-sound correspondence and word reading; and GL Spelling, which included additional training in phonological skills and spelling. During the spring of first grade, the children trained with tablet computers which they could carry with them during the six-week intervention. The average exposure time to training was 5 hr 44 min. The results revealed no differences in the development of reading …
Device-Therapie nach akutem Koronarsyndrom
2014
AV-Blocke sind beim akuten Koronarsyndroms selten. Nur wenige Patienten benotigen eine Schrittmacherimplantation. Besonders beim Hinterwandinfarkt ist die Prognose gut. Die Haufigkeit anhaltender AV-Blockierungen hat durch die Akut-PTCA abgenommen. Ventrikulare Tachyarrhythmien sind in der Akutphase des Infarktes haufig. Treten sie als anhaltende Kammertachykardien oder Kammerflimmern > 48 Stunden nach Infarkt auf, konnen sie eine Indikation zur sekundarprophylaktischen ICD-Implantation darstellen. Primarprophylaktisch sollte ein Defibrillator implantiert werden, wenn die LV-EF auch > 40 Tage nach Infarkt ≤ 35 % betragt. Ist fruh nach Infarkt eine Aggregatimplantation erforderlich, sollte b…
New developments in simulation-based harbour crane training
2011
This paper presents the efforts that have been made during the development of a set of harbour training simulators to improve their quality. The paper focuses on two main research lines: the improvement of complex physical systems involved in the simulation and the analysis of hardware architecture solutions. Cable-based hoist systems and bulk materials are systems present in different harbour equipment and are usually simulated with poor quality due to their complexity. In this paper physics-based models for the interactive simulation of these systems are proposed and applied to real cases. Also, different hardware simulator architectures are analysed and different approaches are proposed …
A readout unit for high rate applications
2002
The LHCb readout unit (RU) is a custom entry stage to the readout network of a data-acquisition or trigger system. It performs subevent building from multiple link inputs toward a readout network via a PCI network interface or alternatively toward a high-speed link, via an S-link interface. Incoming event fragments are derandomized, buffered and assembled into single subevents. This process is based on a low-overhead framing convention and matching of equal event numbers. Programmable logic is used both in the input and output stages of the RU module, which may be configured either as a data-link multiplexer or as entry stage to a readout or trigger network. All FPGAs are interconnected via…
Early cardiac unloading with ImpellaCP™ in acute myocardial infarction with ventricular septal defect
2020
Abstract Despite a relative contraindication, mechanical support with Impella™ left ventricular assist device has already been described for ischaemic ventricular septal defect treatment, either as a bridge to surgery, as intraoperative mechanical haemodynamic support, or to ensure intraprocedural haemodynamic stability during device closure. We describe two cases of ventricular septal defect complicating acute myocardial infarction, where the percutaneous ImpellaCP was implanted early (differently than previously described) with the aim of preventing haemodynamic instability, while deferring surgical repair. We present a report of haemodynamic, echocardiographic, biochemical, and clinical …
