Novel VAMPIRE algorithms for quantitative analysis of the retinal vasculature

2013

This paper summarizes three recent, novel algorithms developed within VAMPIRE, namely optic disc and macula detection, arteryvein classification, and enhancement of binary vessel masks, and their performance assessment. VAMPIRE is an international collaboration growing a suite of software tools to allow efficient quantification of morphological properties of the retinal vasculature in large collections of fundus camera images. VAMPIRE measurements are currently mostly used in biomarker research, i.e., investigating associations between the morphology of the retinal vasculature and a number of clinical and cognitive conditions.

Operators in Rigged Hilbert Spaces, Gel’fand Bases and Generalized Eigenvalues

2022

Given a self-adjoint operator A in a Hilbert space H, we analyze its spectral behavior when it is expressed in terms of generalized eigenvectors. Using the formalism of Gel’fand distribution bases, we explore the conditions for the generalized eigenspaces to be one-dimensional, i.e., for A to have a simple spectrum.

Ecologia e selvicoltura dei boschi artificiali di conifere dei Monti Sicani (Sicilia)

2009

I rimboschimenti realizzati in Sicilia dopo il 1950 hanno contribuito notevolmente all’aumento della superficie forestale nell’Isola. In questo lavoro sono descritte e analizzate le caratteristiche ecologiche e selvicolturali dei rimboschimenti localizzati all’interno dei principali siti della Rete Natura 2000 dei Monti Sicani, con l’obiettivo di formulare idonee linee guida di gestione forestale sostenibile finalizzata ad aumentare la loro stabilità ecologico-strutturale e a favorire così i processi di rinaturalizzazione, diffusi spontaneamente in molte aree. L’indagine conoscitiva è stata condotta in ambiente GIS attraverso l’overlay tra la distribuzione dei rimboschimenti, classificati a…

Grimaces et lèvres pincées : remarques sur la ritualisation pénale (Pascal, Wittgenstein) (Grimaces and Pursed Lips: Remarks on the judicial ritualiz…

2018

Cet article vise à clarifier le recours à une famille de métaphores qui entoure fréquemment le procès (ritualisation, théâtralisation, mise en scène, cérémonie de type religieux), et défend la thèse que la notion de ritualisation judiciaire exprime avant tout la louable intention d'accorder à la justice internationale pénale un temps et des occasions sans finalité préconçue, mais qui permettent la manifestation d'une diversité d'émotions. Il prend principalement appui sur la comparaison des Pensées et des Lettres provinciales de Pascal d'une part, sur le…

Investigation of a Gravel-Bed River’s Pattern Changes: Insights from Satellite Images

2021

Changes in river pattern have been documented in the literature. The recognition of islands and vegetated patches, which is indicative of the evolution processes, requires simultaneous information at different points and at different times and field studies are still difficult and scarce. The present work, focusing the attention on a gravel-bed river, explores the possibility to conduct a first-step pattern changes analysis by identifying the evolution of the morphological features and taking information of islands and vegetated patches from satellite images easily available from Google Earth. The study is conducted by combining the information taken from both the satellite images and the f…

Standardization of Road Danger Signs in the European Union

2015

The aim of this research is to find a solution for the standardization of road signs in the EU zone by a comparative analysis of different national sign systems to establish a common set from a single country. This work is based on the idea that road sign standardization might increase the safety level of transnational journeys and foster the relationships among the various members of the EU Community. This paper presents the outcome of the first step of the research, which focuses on the harmonization of danger signs. In more detail, a multicriteria approach is applied to rank 19 EU Member States on the basis of three main aspects: the installation cost of new signs, new sign learning issu…

Chirurgische Ausbildung im digitalen Zeitalter – Virtual Reality, Augmented Reality und Robotik im Medizinstudium

2021

The digital transformation of healthcare is changing the medical profession. Augmented/Virtual Reality (AR/VR) and robotics are being increasingly used in different clinical contexts and require supporting education and training, which must begin within the medical school. There is currently a large discrepancy between the high demand and the number of scientifically proven concepts. The aim of this thesis was the conceptual design and structured evaluation of a newly developed learning/teaching concept for the digital transformation of medicine, with a special focus on the influence of surgical teaching.Thirty-five students participated in three courses of the blended learning curriculum "…
