Towards a Decision Support Framework for Forensic Analysis of Dynamic Signatures
No full textThis paper presents a preliminary easy to explain and effective framework for supporting dynamic signature analysis in forensic settings. The proposed approach is based on measuring similarities among signatures by applying Dynamic Time Warping on easy to derive dynamic measures. The long term goal of our research is to provide forensic handwriting examiners with a decision support tool to perform reproducible and less questionable inference
Animal board invited review - Beef for future: technologies for a sustainable and profitable beef industry
No full textThe global consumption, notably in developing countries, and production of beef are increasing continuously, and this requires the industry to improve performance and to reduce the environmental impact of the production chain. Since the improvement in efficiency and the highest impacts occur at farm level, it is appropriate to focus on the profitability and environmental sustainability of these enterprises. In many areas of the world, beef production is economically and socially relevant because it accounts for a significant portion of the agricultural production and represents a vital economic activity in mountain and hill districts of many regions, where few alternatives for other agricultural production exist. Due to the important role in the agricultural and food economy worldwide, the future of the beef industry is linked to the reduction of ecological impacts, mainly adopting the agroecological mitigation practices, and the simultaneous improvement of production performances and of product quality. This review analyses the technical and managerial solutions currently available to increase the efficiency of the beef industry and, at the same time, to reduce its environmental impacts in response to the growing concerns and awareness of citizens and consumers.

No full textBackgroundEncephalitis is an uncommon but severe disorder due to an inflammation of the brain parenchyma, usually diagnosed on clinical, laboratory, electroencephalographic, and neuroradiological features. New causes of encephalitis have been reported in recent years, so diagnostic criteria have changed over time.We report on a single-center experience of a pediatric Hospital, the hub of its region, over 12 years (2008-2021), with the evaluation of all children managed for acute encephalitis.MethodsWe retrospectively reviewed clinical, laboratory, neuroradiological, and EEG data from the acute phase and outcome of all immunocompetent patients diagnosed with acute encephalitis. According to the newly proposed criteria for pediatric autoimmune encephalitis, we divided patients into infectious, definite autoimmune, probable autoimmune, and possible autoimmune, and performed a comparison between the different groups.Results48 patients (26 females, mean age 4.4 years), 19 with infections, and 29 with autoimmune encephalitis, were included. Herpes simplex virus 1 encephalitis was the most frequently identified etiology followed by anti-NMDA receptor encephalitis. Movement disorders at onset and a longer hospital stay were observed more frequently in autoimmune compared to infectious encephalitis (pp < 0.001 and p = 0.001, respectively).Among the autoimmune group, children who started immunomodulatory treatment earlier (within 7 days from onset) had more frequent complete functional recovery (p = 0.002).ConclusionsHerpes virus and anti-NMDAR encephalitis are the most frequent etiologies within our cohort. Clinical onset and course are extremely variable. Since early immunomodulatory treatment was associated with a better functional outcome, our data confirm that a timely diagnostic classification in definite, probable, or possible autoimmune encephalitis can help the clinician in a successful therapeutic approach

Aim of this study was to evaluate growth performance and meat
quality of buffalo bulls fed two diets with different maize silage
contents. Compositions (kg/head/d) of low (LS) and high silage
diets (HS) were the following: maize silage 3.0 vs 10.5; alfalfa hay 0 vs 2.0; barley 0.25 vs 0.75; wheat flour middlings 1.0 vs 1.0; wheat straw 3.0 vs 0; commercial concentrate for lactating buffalo cows 0 vs 2.5; commercial concentrate for young buffalo bulls 4.5 vs 0. The diets were approximately isoenergetic [0.92 vs 0.91 Milk FU/kg dry matter (DM)] and isonitrogenous (14.7 vs 14.7 CP% DM).
Fourteen young buffalo bulls (316±70 days of age and 436±67 kglive weight) were assigned into the two dietary groups. Average
daily gain (ADG) was calculated every 2 weeks, along with DM
intake (DMI), calculated on pen basis. On a subgroup of 4 individuals per groups, carcass traits were recorded at slaughter. Meat quality (hardness, cohesion, chewiness, WB shear force) and
meat colour (L*, a*, b*) were evaluated on 7-day aged muscles
(Longissimus dorsi, Semitendinosus, Semimembranosus). DMI
and carcass traits were analyzed by one-way ANOVA. ADG and
meat quality parameters were analyzed by a linear mixed model
for repeated measures. No differences were observed for diet DMI (8.41 vs 8.64 kg DM/day for LS and HS diets, respectively; SE 0.44), as a consequence ADG did not differ between the groups (0.92 vs 0.89 kg/day; SE 0.04). All carcasses had the same carcass conformation (O) and fatness (4) scores. No differences were observed for carcass traits (carcass weight 250 vs 249 kg; SE 8.13; dressing percentages 52.1 vs 50.6%; SE 1.1) and any meat quality parameters.
Therefore, maize silage can be either used as the primary
source of roughage or in combination with other forages without
affecting growth performance and meat quality

No full textIl Futuro della Cybersecurity in Italia: Ambiti Progettuali Strategici
No full textIl presente volume nasce come continuazione del precedente, con l’obiettivo di delineare un insieme di ambiti progettuali e di azioni che la comunità nazionale della ricerca ritiene essenziali a complemento e a supporto di quelli previsti nel DPCM Gentiloni in materia di sicurezza cibernetica, pubblicato nel febbraio del 2017. La lettura non richiede particolari conoscenze tecniche; il testo è fruibile da chiunque utilizzi strumenti informatici o navighi in rete.
Nel volume vengono considerati molteplici aspetti della cybersecurity, che vanno dalla definizione di infrastrutture e centri necessari a organizzare la difesa alle azioni e alle tecnologie da sviluppare per essere protetti al meglio, dall’individuazione delle principali tecnologie da difendere alla proposta di un insieme di azioni orizzontali per la formazione, la sensibilizzazione e la gestione dei rischi. Gli ambiti progettuali e le azioni, che noi speriamo possano svilupparsi nei prossimi anni in Italia, sono poi accompagnate da una serie di raccomandazioni agli organi preposti per affrontare al meglio, e da Paese consapevole, la sfida della trasformazione digitale. Le raccomandazioni non intendono essere esaustive, ma vanno a toccare dei punti che riteniamo essenziali per una corretta implementazione di una politica di sicurezza cibernetica a livello nazionale. Politica che, per sua natura, dovrà necessariamente essere dinamica e in continua evoluzione in base ai cambiamenti tecnologici, normativi, sociali e geopolitici. All’interno del volume, sono riportati dei riquadri con sfondo violetto o grigio; i primi sono usati nel capitolo introduttivo e nelle conclusioni per mettere in evidenza alcuni concetti ritenuti importanti, i secondi sono usati negli altri capitoli per spiegare il significato di alcuni termini tecnici comunemente utilizzati dagli addetti ai lavori.
In conclusione, ringraziamo tutti i colleghi che hanno contribuito a questo volume: un gruppo di oltre 120 ricercatori, provenienti da circa 40 tra Enti di Ricerca e Università, unico per numerosità ed eccellenza, che rappresenta il meglio della ricerca in Italia nel settore della cybersecurity. Un grazie speciale va a Gabriella Caramagno e ad Angela Miola che hanno contribuito a tutte le fasi di produzione del libro. Tra i ringraziamenti ci fa piacere aggiungere il supporto ottenuto dai partecipanti al progetto FILIERASICURA
