Methods and Techniques for Multi-source Data Analysis and Fusion
This work has been inspired by the recent trend in remote sensing and environmental data acquisition. Remote sensing techniques allow us to measure information about an object without touching it. In the last decades remote sensing via satellites has been used in various applications such as Earth observation, weather and storm predictive analysis, atmospheric monitoring, climate change, human-environment interactions. Sensors on airborne and satellite platforms have been recording signals from space for many years, giving rise to a huge amount of data. Some data are processed on-board but others are treated and post-processed in ground stations. Signal and image processing are widely appli…
Retinal image synthesis through the least action principle
2020
Eye fundus image analysis is a fundamental approach in medical diagnosis and follow-up ophthalmic diagnostics. Manual annotation by experts needs hard work, thus only a small set of annotated vessel structures is available. Examples such as DRIVE and STARE include small sets for training images of fundus image benchmarks. Moreover, there is no vessel structure annotation for a number of fundus image datasets. Synthetic images have been generated by using appropriate parameters for the modeling of vascular networks or by methods developing deep learning techniques and supported by performance hardware. Our methodology aims to produce high-resolution synthetic fundus images alternative to the…
"Ultra vestimenta seu ornamenta ecclesiastica que etiam dedi eidem ecclesie". Tracce di un'eredità palermitana dell'arcivescovo Jean de Carondelet (1…
2016
Lo studio, dopo una breve biografia aggiornata di Jean Carondelet, importante colto ecclesiastico e politico fiammingo, che fu anche arcivescovo di Palermo dal 1520 al 1544, ne indaga la committenza artistica (vetrate istoriate, paramenti sacri ricamati, stalli corali lignei intagliati, manoscritti liturgici miniati, dipinti, sculture marmoree) tra Franca Contea, Paesi Bassi borgognoni e la stessa Palermo, col supporto di un'inedito testamento secondo cui egli avrebbe donato già in vita "vestimenta seu ornamenta ecclesiastica" di grande valore alla cattedrale palermitana, tra cui forse la mitria e il paliotto già tradizionalmente identificati col suo cognome.
Dallo chignon ai capelli sciolti. Stereotipie delle bibliotecarie tra primo e secondo Novecento
2021
The essay focuses on the main stereotypes that have characterized the way of representing the figure of the librarian starting from classic American cinema. Hair gathered in a chignon, shirt buttoned at the neck, glasses, are elements that make the surly, solitary, shy and rude librarians easily recognizable who find their climax in the figure of Miss Anderson in Citizen Kane. In the second half of the twentieth century, however, a radical change took place in the stereotypical representation of this figure and the chignon was replaced by loose hair and the character of the harsh woman gave way to that of the sexy icon.

Arterial Hypertension and the Hidden Disease of the Eye: Diagnostic Tools and Therapeutic Strategies.
2022
Hypertension is a major cardiovascular risk factor that is responsible for a heavy burden of morbidity and mortality worldwide. A critical aspect of cardiovascular risk estimation in hypertensive patients depends on the assessment of hypertension-mediated organ damage (HMOD), namely the generalized structural and functional changes in major organs induced by persistently elevated blood pressure values. The vasculature of the eye shares several common structural, functional, and embryological features with that of the heart, brain, and kidney. Since retinal microcirculation offers the unique advantage of being directly accessible to non-invasive and relatively simple investigation tools, the…
INVERSE RELATIONSHIP BETWEEN CHOROIDAL THICKNESS AND SUBCLINICAL RENAL DAMAGE IN ESSENTIAL HYPERTENSION
2018
The introduction in last years of advanced techniques of optical coherence tomography (OCT) has greatly increased our understanding of the choroid, that is the most important vascular layer of the eye. Our study was aimed to assess choroidal thickness by using Swept-Source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without subclinical renal damage (SRD). We enrolled 100 EHs of which 65 without kidney damage and 35 with SRD. In all the participants SS-OCT and a routine biochemical workup were performed. Glomerular filtration rate (GFR) was estimated by the CKD-EPI equation (eGFR). SRD was defined, by the presence of microalbuminuria or eGFR between 30 and 60 mL/min/1.73 m…
SUBCLINICAL RENAL DAMAGE IS ASSOCIATED WITH A REDUCED CHOROIDAL THICKNESS IN PATIENTS WITH PRIMARY HYPERTENSION
2018
Objective: The retina is considered the easiest accessible window to study the state of the systemic microcirculation, even if the choroid is the most important vascular layer of the eye. Our understanding of the choroid has been greatly increased in last years since the introduction of advanced techniques of optical coherence tomography (OCT). Our study was aimed to assess choroidal thickness by using Swept-Source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without subclinical renal damage (SRD). Design and method: We enrolled 100 EHs of which 65 without kidney damage and 35 with SRD. In all the participants SS-OCT and a routine biochemical work-up were performed. Glomer…
