Intermedialità e amedialità: percorsi del credere e del sapere nelle immagini contemporanee

2020

Oltre sessant’anni dopo la sua scomparsa, il pensiero di André Bazin si rivela ancora di estrema attualità. Dimostra, per esempio, di essere uno strumento utile (forse il più utile) per interpretare il cinema che definiamo “moderno”. Ma c’è di più: la riflessione di Bazin si rivela una chiave interpretativa irrinunciabile nella comprensione di molti fenomeni che interessano la produzione audiovisiva contemporanea, in particolare le nuove forme del documentario. Per il tramite di Bazin, questo volume vuole essere uno strumento utile alla comprensione di quegli oggetti misteriosi che sono le immagini in movimento, anche quando (o forse ancora di più quando) esse dimostrano di tendere verso…

La crise des intellectuels et ses avatars dans "Les Mandarins" de Simone de Beauvoir

2022

In the novel The Mandarins, Simone de Beauvoir shows the crisis of French intellectuals, namely writers facing ideological and political dilemmas after World War Two. Reflecting on the usefulness of their works, the main protagonists ask the fundamental question, namely why / for what to write and act. In the writer’s optics, two solutions are possible. On the one hand, the commitment, and the need for being aware of situations and actions. On the other hand, the idea of the autonomy of literature. This opposition seems to cause a failure of common expectations and hopes, conformism, collapse of values as well as love failures. The history of “broken illusions” of a known milieu allows the …

Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity

2020

Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond tho…

Approximation of pore space with ellipsoids: a comparison of a geometrical method with a statistical one.

2018

International audience; We work with tomographic images of pore space in soil. The images have large dimensions and so in order to speed-up biological simulations (as drainage or diffusion process in soil), we want to describe the pore space with a number of geometrical primitives significantly smaller than the number of voxels in pore space. In this paper, we use the curve skeleton of a volume to segment it into some regions. We describe the method to compute the curve skeleton and to segment it with a simple segment approximation. We approximate each obtained region with an ellipsoid. The set of final ellipsoids represents the geometry of pore space and will be used in future simulations.…

Curvelet-based method for orientation estimation of particles from optical images

2014

A method based on the curvelet transform is introduced to estimate the orientation distribution from two-dimensional images of small anisotropic particles. Orientation of fibers in paper is considered as a particular application of the method. Theoretical aspects of the suitability of this method are discussed and its efficiency is demonstrated with simulated and real images of fibrous systems. Comparison is made with two traditionally used methods of orientation analysis, and the new curvelet-based method is shown to perform better than these tradi- tional methods. peerReviewed

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…

Predicting the availability of users' devices in Decentralized Online Social Networks

2018

The understanding of the user temporal behavior is a crucial aspect for all those systems that rely on user resources for daily operations, such as decentralized online social networks (DOSNs). Indeed, DOSNs exploit the devices of their users to take on and share the tasks needed to provide services such as storing the published data. In the last years, the increasing popularity of DOSN services has changed the way of how people interact with each other by enabling users to connect to these services at any time by using their personal devices (such as notebooks or smartphones). As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…

Computational Modeling of Human Visual Function using Psychophysics, Deep Neural Networks, and Information Theory

2023

Visual perception is a key to unlocking the secrets of brain functions because most of the information is processed through the early visual system and then transmitted to the high-level cognitive perception brain regions. The brain functions as a self-organizing, bio-dynamic, and chaotic system that receives outside information and then decomposes it into pieces of information that can be processed efficiently and independently. The work connects natural image statistics, psychophysics, deep neural networks, and information theory to perceptual vision systems to explore how vision processes information from the outside world and how the information coupled drives functional connectivity be…

Postoperative Sagittal Balance Has Only a Limited Role in the Development of Adjacent Segment Disease After Lumbar Spine Fusion for Degenerative Lumb…

2022

Study Design. Retrospective additional analysis of a prospective follow-up study. Objectives. We aimed to find out whether poor postoperative sagittal alignment increases revisions for adjacent segment disease (ASD) after lumbar spine fusion (LSF) performed for degenerative lumbar spine disease. Summary of Background Data. Revisions for ASD accumulate over time after LSF for degenerative lumbar spine disease. The etiology of ASD is considered multifactorial. Yet, the role of postoperative sagittal balance in this process remains controversial. Materials and Methods. A total of 215 consecutive patients who had undergone an elective LSF surgery for spinal stenosis with (80%) or without (20%) …
