Bitter taste genetics and food preference in italian population

2010

Objective: To investigate the possible role of the polymorphic bitter taste gene, TAS2R38, known to be involved in the perception of the bitter synthetic chemical phenylthiocarbamide (PTC), in influencing food preference and body mass index(BMI). Methods: up to now more than 1500 university students (17-25 years old) at Catania, Cosenza, Rome, Palermo, Pisa, Parma, Chieti, Trento University have been enrolled in the study. DNA was extracted from saliva, and genotyped by TaqMan assay for the most frequent polymorphism (PAV/AVI) of TAS2R38 gene. A possible association between genotype and food preference was assessed by administering a detailed questionnaire for food preferences and life styl…

UTILIZACIÓN DE TÉCNICAS DE FOTO-RECONSTRUCCIÓN 3D AUTOMATIZADA EN GEOMORFOLOGÍA: EJEMPLOS PARA DIFERENTES MORFOLOGÍAS Y ESCALAS

2014

Three-dimensional photo-reconstruction methods based on Structure from Motion (SfM) and MultiView-Stereo techniques (MVS) are tested for measuring, monitoring and quantifying three different geomorphological features: i) the Corral del Veleta rock glacier and ii) five small gully headcuts in Spain and iii) Calanchi type badland in Italy. Results about the accuracy, usefulness and applicability of these techniques are presented here. The results of these analyses showed centimeter-level accuracies with average distances to the benchmark models ranging from 0.009 m to 0.42 m.

A Quantum-Inspired Classifier for Early Web Bot Detection

2022

This paper introduces a novel approach, inspired by the principles of Quantum Computing, to address web bot detection in terms of real-time classification of an incoming data stream of HTTP request headers, in order to ensure the shortest decision time with the highest accuracy. The proposed approach exploits the analogy between the intrinsic correlation of two or more particles and the dependence of each HTTP request on the preceding ones. Starting from the a-posteriori probability of each request to belong to a particular class, it is possible to assign a Qubit state representing a combination of the aforementioned probabilities for all available observations of the time series. By levera…

EntityBot: Supporting Everyday Digital Tasks with Entity Recommendations

2021

Everyday digital tasks can highly benefit from systems that recommend the right information to use at the right time. However, existing solutions typically support only specific applications and tasks. In this demo, we showcase EntityBot, a system that captures context across application boundaries and recommends information entities related to the current task. The user’s digital activity is continuously monitored by capturing all content on the computer screen using optical character recognition. This includes all applications and services being used and specific to individuals’ computer usages such as instant messaging, emailing, web browsing, and word processing. A linear model is then …

Analisi di sicurezza nella procedura di protonterapia oculare applicata presso i Laboratori del Sud dell’INFN di Catania

2017

A partire dal 2002, l’Azienda Ospedaliera Universitaria “Policlinico Vittorio Emanuele” di Catania ha effettuato il trattamento di circa 350 pazienti affetti da neoplasie oculari mediante fasci di protoni prodotti con il ciclotrone disponibile presso i Laboratori nazionali del Sud (LNS). Tale impianto viene utilizzato per attività di ricerca nell’ambito della fisica sperimentale, per cui è stato necessario modificare le caratteristiche del fascio, rendendolo idoneo alle applicazioni cliniche. Il lavoro di ricerca ha riguardato lo svolgimento della analisi del rischio volto ad individuare possibili fallimenti nelle procedure adottate per il trattamento del paziente sottoposto a cicli di prot…

Time-Constrained Node Visit Planning for Collaborative UAV-WSN Distributed Applications.

2022

Unmanned Aerial Vehicles (UAVs) are often studied as tools to perform data collection from Wireless Sensor Networks (WSNs). Path planning is a fundamental aspect of this endeavor. Works in the current literature assume that data are always ready to be retrieved when the UAV passes. This operational model is quite rigid and does not allow for the integration of the UAV as a computational object playing an active role in the network. In fact, the UAV could begin the computation on a first visit and retrieve the data later. Potentially, the UAV could orchestrate the distributed computation to improve its performance, change its parameters, and even upload new applications to the sensor network…

Input for baroreflex analysis: which blood pressure signal should be used?

2022

The baroreflex (BR) is an important physiological regulatory mechanism which reacts to blood pressure perturbations with reflex changes of target variables such as the heart period (electrocardiogram derived RR interval) or the peripheral vascular resistance (PVR). Evaluation of cardiac chronotropic (RR as a target variable) and vascular resistance (target PVR) BR arms was in previous studies mainly based on the use of the spontaneous variability of the systolic or diastolic blood pressure (SBP, DBP), respectively, as the input signals. The use of other blood pressure measures such as the mean blood pressure (MBP) as an input signal for BR analysis is still under investigation. Making the a…

I ritardi di pagamento e la novella dell'art. 1284 c.c.

2016

Il capitolo analizza la novella dell'art. 1284 c.c. attuata dall'art. 17, d.l. 12 settembre 2014, n. 132, convertito nella l. 10 novembre 2014, n. 162. Tale significativa modifica viene letta alla luce delle riflessioni che si sono sviluppate intorno al modello cui i nuovi commi 4 e 5 dell'art. 1284 c.c. rinviano, ossia la disciplina degli interessi di mora nella normativa di origine europea sui ritardi di pagamento nelle transazioni commerciali.

Open government in Italy and in the Sicilian Region

2018

This short essay collects contributions and documentation relating to Rapporto sull’Open Government in Sicilia 2015 (the second Report on Open Government in Sicily), presented in March 31th, 2015 in the DEMS department lecture hall at the University of Palermo. It is the result of the research carried out in the course compendium of European Administrative Law of the academic year of 2014-2015 and of the master’s degree in Science of administration and complex organizations. The introductory essay was then presented in the form of a report 2014 to the Roundtable on Administrative transparency after the Legislative Decree no. 33/2013, which was organized at the Faculty of Law, University of …
