Les atteintes à l’image en Turquie : étude de cas d’un fléau numérique ravageur
Get PDFLa littérature scientifique, mais également les cas médiatiques font aujourd’hui état de pratiques délinquantes toujours plus
variées liées à l’utilisation des technologies numériques.
Ces atteintes à la personne, qui remettent en question la dignité et la réputation de l’individu, prennent de l’ampleur en
Turquie. On constate une recrudescence des agressions en ligne (ex. vol de données…) mais aussi des atteintes à l’image par
lesquelles les représentations du corps de la victime se voient partagées, de manière non consentie, avec une foule
d’anonymes. Ainsi, malgré l’inexistence d’une quelconque « corporalité » dans l’espace numérique, les cyberviolences
semblent systématiquement porter sur le corps et par là, visent à remettre en question non seulement l’image sociale (la
réputation) mais aussi l’image personnelle (la dignité humaine) de la personne.
Dans cet article, il s’agira tout d’abord de rendre compte de la littérature scientifique en Turquie et de voir comment les
cyberviolences ont été appréhendées dans ce contexte. Puis, dans un deuxième temps, à partir de cas journalistiques, nous
proposerons une vue d’ensemble des cas d’atteinte à l’image recensés en Turquie entre 2017-2022. Nous tenterons de
dégager les récurrences liées aux violences numériques relevant des atteintes à l’image sociale. Enfin, nous nous pencherons
sur les réponses juridiques et judiciaires proposées par les instances turques en vue de combattre ces phénomènes
Searching for neutrinoless double beta decay with the AMoRE experiments
No full textSearches for the neutrinoless double beta decay (0νDBD) have been pursued for decades by many researchers since it is a viable channel to probe the lepton number violating process and unveil some unknown properties of neutrino. The AMoRE experiments have been searching for 0νDBD of 100Mo isotope using molybdate crystal scintillators. The experiments used the molybdate crystals as the absorber for the cryogenic calorimeter, which measures the energetic phonons and scintillation lights from the particle interaction in the crystal absorber. The experiments have been scheduled as several phases of AMoRE-pilot, AMoRE-I and AMoRE-II with the significant increase in the absorber mass and reduction of the background level for each upgrade. Currently, we are running AMoRE-I experiment, which uses 6.2 kg of molybdate crystal absorbers, and preparing for AMoRE-II experiment, which will exploit 100 kg of 100Mo isotopes, ultimately. The overall status of the AMoRE experiments is presented in the paper
The anomalous magnetic moment of the muon: Beyond the Standard Model via chiral enhancement
No full textThe anomalous magnetic moment of the muon displays a 4.2σ tension with the Standard-Model prediction, if e+e− → hadrons data are used for hadronic vacuum polarization. In these proceedings we review possible explanations of this anomaly in terms of heavy new particles. As the necessary effect is of the order of the electroweak Standard-Model contribution, viable explanations with TeV-scale physics must involve an enhancement factor; in particular, one can obtain the chirality flip of the dipole operator via a sizable coupling to the Higgs doublet instead of the small muon Yukawa coupling. Such Standard-Model extensions then
also predict effects in Higgs and Z-boson decays to muons, with details depending on the SU(2)L × U(1)Y representations of the new particles. We first review the general case of chirally enhanced new physics, before discussing in more detail the concrete example of leptoquark models
LFU ratios in B decays using Lattice QCD and Unitarity
No full textWe present the results of the application of the unitarity-based Dispersion Matrix approach to semileptonic charged-current B decays. This method allows to achieve a non-perturbative and completely model-independent determination of the hadronic form factors. Starting from lattice results available at large values of the momentum transfer, the behaviour of the form factors in their whole kinematical range is obtained without introducing any explicit parameterization of their momentum dependence. We will focus on the analysis of Lepton Flavour Universality by computing the τ /μ ratios of the branching fractions of the B → D(∗)
ν and B → πν decays. The most important result is that, for the first time, the discrepancies between the SM expectation values and the measurements of the Lepton Flavour Universality ratios for the B → D(∗) ν decays are reduced at the 1.3σ level for each of the two channels, separately
Multi-scale 5D models for flavor hierarchies and anomalies
No full textSo-called 4321 gauge models at the TeV scale with hierarchical couplings reminiscent of the Standard Model Yukawas offer a coherent combined explanation of the recent B-meson anomalies. In these proceedings, based on arXiv:2203.01952, we discuss how such models could arise from a multi-scale theory of flavor, based on a warped fifth dimension with three branes. This higher dimensional construction provides a natural description of flavor hierarchies, addresses the electroweak hierarchy problem, and allows for the Higgs to be identified as a pseudo-Nambu-Goldstone boson emerging from the same dynamics responsible for the breaking of 4321 gauge symmetry
Displaced vertex search for heavy neutral leptons with the ATLAS detector
No full textThe results of a search for long-lived heavy neutral leptons (HNLs) in proton-proton collisions at the Large Hadron Collider are presented. The Standard Model (SM) of particle physics is an extremely successful theory and its major predictions have been precisely confirmed. However, the existence of neutrinos, with small nonzero masses, provides evidence that the SM is incomplete. Introducing HNLs into the SM is a natural way to generate the light neutrino masses through a seesaw mechanism. This search uses 139 fb−1 of ATLAS experimental data collected between 2015 and 2018 at a centre-of-mass energy of 13 TeV. A non-standard
technique is used to search for a displaced vertex from particle trajectories produced in the HNL decay to leptons. The dominant background from uncorrelated leptons crossing in the ATLAS detector is estimated using an object shuffling method. The reconstructed HNL mass is used to discriminate between signal and background. No excess of events is observed and constraints on the strength of the interactions
between HNLs and neutrinos are imposed in various scenarios
Acquisizioni di dati petrofisici mediante Multi Sensor Core Logger MSCL-S GEOTEK
Get PDFNell’ambito del progetto SeaGMA (Geochemical and Microbiological Assessment of the sea: a
combed survey for abiotic/biotic resources mapping), sono state eseguite due campagne
(SeaGMA-2022 e SeaGMA-2023) nel mare Tirreno con la Nave da Ricerca R/V Dallaporta.
L’obiettivo principale della campagna è stata l’acquisizione di campioni di sedimento di fondo e di
acque marine, su maglie di campionature equidistanti per analisi geochimiche e petrofisiche. I
campioni di sedimento sono stati prelevati mediante Box Corer con risoluzione stratigrafica di circa
20 cm e diametro 8 cm. Durante le due campagne, sono state prelevate rispettivamente
101 e 25 carote.Le carote sono state successivamente analizzate con il Multi-Sensor Core Logger (MSCL-S _Geotek)
che esegue misure petrofisiche, multiparametriche non distruttive ed in continuo di sedimento
marino, presso il laboratorio di petrofisica del ISMAR_CNR sezione di Napoli.
Il presente rapporto tecnico è finalizzato alla descrizione delle attività tecnico - scientifiche svolte
Metodi di inclusione nella ricerca
Get PDFThe chapter emphasizes the role of Equality, Diversity, and Inclusion (EDI) in enhancing innovation and creativity within scientific research, thereby improving outcomes and societal impact. The authors outline the European Union’s efforts in promoting equality and inclusion in scientific research since the 1990s, initially focusing on gender equality and later broadening to encompass diverse perspectives in Science, Technology, Engineering, Mathematics (STEM) fields, shifting towards an EDI approach. Challenges faced in promoting gender equality and integrating EDI perspectives into research institutions, particularly during research activities, are discussed. Then, scientific initiatives in chemistry and materials science, particularly nanosciences, in Italy, are showcased, emphasizing an EDI -friendly approach. Ultimately, the adoption of EDI perspectives in STEM disciplines could lead to a reduction in unequal access to STEM, including nanotechnologies, and unequal opportunities in research and innovation
The “Northern Syndrome”. The human dimension of the fight against the terrorist organization ETA
Get PDFFor more than forty years, Spain has been confronted with internal terrorism, of an ethno-nationalist nature, deployed by the terrorist organization ETA. Their armed struggle, which caused more than 850 fatalities, had as its objective the independence of the Basque Country, Navarre, as well as a part of the so-called French Basque Country. It was especially during the 1970s, 1980s and 1990s when the police forces deployed in the so-called “Northern Zone” were exposed not only to the possibility of suffering a terrorist attack, but also to the rejection and animosity of a large part of the Basque a Navarrese population, which considered the police as an “occupation force”. This gave rise to the concept of “Northern Syndrome”, which referred, above all, to the psychological consequences that this omnipresent terror and rejection in their daily lives produced in both the police officers and their families. Based on these considerations, the objective of the present work is to analyse said psycho-pathological construct. To this end, the author of this paper has conducted a total of 25 interviews with police officers and relatives who were stationed in the Basque Country and Navarra during the so-called “years of lead”. As will be seen, practically all of the individuals interviewed affirm not only the existence of said Syndrome, but also having suffered from it during their stay in the North and, in some cases, also currently
