Introducing Pseudo-Singularity Points for Efficient Fingerprints Classification and Recognition
2010
Fingerprint classification and matching are two key issues in automatic fingerprint recognition. Generally, fingerprint recognition is based on a set of relevant local characteristics, such as ridge ending and bifurcation (minutiae). Fingerprint classification is based on fingerprint global features, such as core and delta singularity points. Unfortunately, singularity points are not always present in a fingerprint image: the acquisition process is not ideal, so that the fingerprint is broken, or the fingerprint belongs to the arch class. In the above cases, pseudo-singularity-points will be detected and extracted to make possible fingerprint classification and matching. As result, fingerpr…
Verga e la poetica del vero nella cultura figurativa di Francesco Lojacono, Antonino Leto e Onofrio Tomaselli
2020
Il ritrovamento di un bozzetto inedito per I carusi del 1905 circa di Onofrio Tomaselli offre lo spunto per una riflessione sulla presenza cruciale dei temi veristi nella cultura figurativa siciliana tra XIX e XX secolo. Con riferimenti trasversali al collezionismo, alla letteratura e alla fotografia, il contributo approfondisce il tema dell’influenza di Giovanni Verga sulla pittura siciliana focalizzandosi sulla produzione di Francesco Lojacono, Antonino Leto e Onofrio Tomaselli e sulla loro affinità con Nedda, I Malavoglia e Rosso Malpelo. The discovery of an unpublished sketch for I carusi by Onofrio Tomaselli (1905 ca) invites us to reflect on the crucial presence of realist themes in S…

L'esordio teatrale di Rosso di San Secondo

Spigolature onomastiche nel teatro sansecondiano degli anni Venti, tra non nomi ed espressionismo cromatico
2021
La produzione teatrale e narrativa di Pier Maria Rosso di San Secondo si distende per circa un quarantennio tra gli anni ‘10 e gli anni ‘50 del XX secolo. Anni di transizione e di ridefinizione dei ruoli e degli spazi individuali e sociali: i rapporti secolari tra i generi, tra le classi, tra le Nazioni, si stravolgono e approdano attraverso percorsi complessi e conflittuali verso nuovi equilibri mai scevri da lacerazioni. La coscienza di molti autori, basculante e nevrotica, trova nel teatro la dimensione naturale in cui mettere in scena questo sentimento di colpa e dolore, di frantumazione della soggettività e di perdita di punti di riferimento. Cresciuto nel più importante centro zolfife…

New Molecular-Based Materials for Enabling Electro-Optical Bistability in the Silicon Photonics Platform
2019
Electro-optical bistability is a functionality which can be crucial for a wide range of applications as it can enable non-volatile and ultra-low power switching performance. We investigate the integration of a molecular-based material presenting a Spin Crossover (SCO) effect in the silicon platform for enabling optical bistability. The SCO phenomenon involves a switching process between two molecular spin states. This spin transition comes along with a change in the optical refractive index that can be switched by different external stimuli such as a variation of temperature or light irradiation and which has a hysteretic behaviour. The SCO material can be synthetized as nanoparticles so th…
Tuning size and thermal hysteresis in bistable spin crossover nanoparticles.
2010
Nanoparticles of iron(II) triazole salts have been prepared from water-organic microemulsions. The mean size of the nanoparticles can be tuned down to 6 nm in diameter, with a narrow size distribution. A sharp spin transition from the low spin (LS) to the high spin (HS) state is observed above room temperature, with a 30-40-K-wide thermal hysteresis. The same preparation can yield second generation nanoparticles containing molecular alloys by mixing triazole with triazole derivatives, or from metallic mixtures of iron(II) and zinc(II). In these nanoparticles of 10-15 nm, the spin transition "moves" towards lower temperatures, reaching a 316 K limit for the cooling down transition and mainta…
A influência de fatores psicossociais protetores sobre a incidência de dor dentária
2022
ABSTRACT OBJECTIVE To investigate the influence of protective psychosocial factors on the incidence of dental pain in the last six months among 12-year-old children living in Manaus (AM). METHODS A prospective school-based cohort study was conducted with 210 12-year-old students enrolled in public schools in the eastern zone of Manaus (AM). Students were followed up for two years. Validated questionnaires were used to assess sociodemographic characteristics, protective psychosocial factors, including sense of coherence, social support, and self-esteem at baseline and after two years. Calibrated examiners clinically assessed dental caries and gingival bleeding. Multivariate multilevel Poisso…
Ramucirumab in elderly patients with hepatocellular carcinoma and elevated alpha-fetoprotein after sorafenib in REACH and REACH-2.
2020
Background & Aims: Limited data on treatment of elderly patients with hepatocellular carcinoma (HCC) increase the unmet need. REACH and REACH-2 were global phase III studies of ramucirumab in patients with HCC after prior sorafenib, where patients with alpha-fetoprotein (AFP) ≥400 ng/mL showed an overall ssurvival (OS) benefit for ramucirumab. These post-hoc analyses examined efficacy and safety of ramucirumab in patients with HCC and baseline AFP ≥ 400 ng/mL by three prespecified age subgroups (<65, ≥65 to <75 and ≥75 years). Methods: Individual patient data were pooled from REACH (baseline AFP ≥400 ng/mL) and REACH-2. Kaplan-Meier and Cox proportional hazards regression methods …
