Emergenza sanitaria e trattamento dei dati personali
2020
Il saggio analizza le norme emergenziali di contrasto della pandemia da COVID-19 che hanno un impatto sui dati personali dei cittadini, verificandone la conformità alla disciplina generale europea e nazione sulla protezione dei dati personali e la loro influenza. Lo studio dedica particolare attenzione all’analisi del sistema di tracciamento dei contagi delineato dall’art. 6 d.l. 29 aprile 2020, n. 28 e convertito nella legge 25.6.2020, n. 70 e alle sue ricadute sulla protezione dell’individuo rispetto alla circolazione dei dati personali. The essay analyzes the emergency provisions againsts the COVID-19 pandemic that have an impact on citizens' personal data, verifying their compliance wit…
Use of ICT to support epidemiological surveillance on a community of university students during SARS-CoV-2 phase 3 pandemic
2021
Populations documenting to date low incidence rates of SARS-CoV-2 infection are immunologically susceptible and at high exposure risk of new COVID-19 outbreaks during phase 3 of the pandemic. Following the experience documented by other countries with regard to the use of Information Communication Technology (ICT) to counteract the current pandemic, Italy has implemented a contact tracing system based on a mobile application. In this work, we describe the proposal of a complementary ICT-based prototypal model of COVID-19 prevention and surveillance system, involving the university students as sentinels acting both in the academic community and the general population.
Trigeminal innervation of the mammalian pineal gland.
1999
There is evidence that the trigeminal (Gasserian) ganglia innervate the mamma- lian pineal gland and serve in its regulation in addition to the sympathetic and cholinergic as well as further influences. By means of immunohistochemical methods, previous studies demonstrated fibers containing calcitonin gene-related peptide (CGRP-LI) or substance P (SP) in the superficial pineal of various mammalian species. In addition, SP and the related tachykinin, neurokinin A, were detected by radioimmunoassay and HPLC, respectively, in the rat and human pineal gland. In the present study, retrograde neuronal tracing upon injection of a tracer substance into the superfical pineal gland of rats was used i…
Olfactory and cortical projections to bulbar and hippocampal adult-born neurons
2015
New neurons are continually generated in the subependymal layer of the lateral ventricles and the subgranular zone of dentate gyrus during adulthood. In the subventricular zone, neuroblasts migrate a long distance to the olfactory bulb where they differentiate into granule or periglomerular interneurons. In the hippocampus, neuroblasts migrate a short distance from the subgranular zone to the granule cell layer of the dentate gyrus to become granule neurons. In addition to the short-distance inputs, bulbar interneurons receive long-distance centrifugal afferents from olfactory-recipient structures. Similarly, dentate granule cells receive differential inputs from the medial and lateral ento…
Figure del contagio. Dalle topografie mediche al contact tracing: trasformazioni nell’architettura e nel paesaggio urbano
2021
Ita_Il tracciamento del contagio, fra le più efficaci forme globali di difesa dal coronavirus, viene ripercorso mettendo in luce il rapporto fra pensiero architettonico e spazio delle epidemie negli ultimi due secoli. La relazione fra la diffusione delle malattie e le forme del costruito è stata infatti compresa nella seconda metà dell’Ottocento attraverso le mappature tematiche, secondo metodi ancora oggi in evoluzione. A partire dalle topografie mediche comparse per la prima volta in Francia nel XIX secolo, interpolate con le intuizioni di J. Snow sulla base delle mappe da lui elaborate nello stesso periodo in Inghilterra, si evidenziano i modi di formazione di un regime di sapere teso fr…
Distribution and projections of nitric oxide synthase neurons in the rodent superior olivary complex.
2000
The superior olivary complex (SOC), a group of interrelated brainstem nuclei, sends efferents to a variety of neuronal structures including the cochlea and the inferior colliculus. The present review describes data obtained from rodents providing evidence that the gaseous, short-living neuroactive substance nitric oxide (NO) is produced in the SOC. The NO-synthesizing enzyme neuronal NO-synthase (nNOS) has been localized by means of several methods including histochemistry and immunohistochemistry. Perikarya containing nNOS were found in several nuclei of the SOC. Their largest numbers and percentages of total cells were observed in the medial nucleus of the trapezoid body. Stained terminal…
The global flood of COVID-19 contact tracing apps: sailing with human rights and data protection standards against the wind of mass surveillance
2021
Research background: Countries all around the world are rapidly introducing contact tracing apps and other surveillance technologies to tackle the spread of COVID-19 raising serious concerns about human rights and democratic principles. Purpose of the article: The article aims to analyse how human rights and data protection law regulate the COVID-19 contact tracing apps and reveal the biggest challenges that countries face in applying the essential requirements. Methods: The article will analyse the legal framework and compare many guidance documents issued by the international organisations, including the Council of Europe, the OECD and many EU institutions on the data protection requireme…
Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system
2011
Rodents constitute good models for studying the neural basis of socio-sexual behaviour. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, the neural pathways mediating this basic socio-sexual behaviour remain elusive. Since previous work indicates that the dopaminergic tegmento-striatal pathway is not involved in pheromone reward, the present report explores alternative pathways linking the vomeronasal system with the tegmento-striatal system (the limbic basal ganglia) by means of tract-tracing experiments studying direct and indirect projections from the chemosensory amygdala to the ventral striato-pall…
GPGPU-säteenseuranta
2012
Säteenseuranta on rinnakkaistuva ja laskentaintensiivinen tapa tuottaa kolmiulotteista tietokonegrafiikkaa. Yleiskäyttöiset grafiikkaprosessorit (GPGPU) ovat tehokkaita rinnakkaislaskentaprosessoreita, joiden avulla voidaan kiihdyttää säteenseurantaa. Tässä tutkielmassa käsitellään säteenseurannan toteuttamista yleiskäyttöisillä grafiikkaprosessoreilla ja esitetään rakenne yksinkertaiselle GPGPU-säteenseurantaohjelmalle. Käsittelyn aiheena ovat myös säteenseurantaa kiihdyttävien menetelmien, kuten kiihdytysrakenteiden, toteuttaminen GPGPU-laskennalla. Ray tracing is a parallel and computationally intensive way of producing three dimensional computer graphics. General-purpose graphics proces…
HYPERBLEND: SIMULATING SPECTRAL REFLECTANCE AND TRANSMITTANCE OF LEAF TISSUE WITH BLENDER
2022
Abstract. Remotely sensing vegetation condition and health hazards requires modeling the connection of plants’ biophysical and biochemical parameters to their spectral response. Even though many models exist already, the field suffers from lack of access to program code. In this study, we will assess the feasibility of open-source 3D-modeling and rendering software Blender in simulating hyperspectral reflectance and transmittance of leaf tissue to serve as a base for a more advanced large-scale simulator. This is the first phase of a larger HyperBlend project, which will provide a fully open-source, canopy scale leaf optical properties model for simulating remotely sensed hyperspectral imag…
