Observational study on risk factors determining residual dizziness after successful benign paroxysmal positional vertigo treatment: The role of subcl…
2018
Studio osservazionale sui fattori di rischio che causano residual dizziness dopo il trattamento della vertigine parossistica posizionale benigna: il ruolo della VPPB subclinica.Alcuni pazienti, dopo il trattamento della vertigine parossistica posizionale benigna concluso con successo, possono lamentare un disequilibrio residuo. La possibile spiegazione potrebbe essere: la persistenza di otoliti canalari insufficienti a provocare un nistagmo clinicamente evidente, una disfunzione utriculare, coesistenza di altri disordini del sistema vestibolare. Abbiamo condotto uno studio osservazionale prospettico caso-controllo, focalizzando l’attenzione sul ruolo di fattori di rischio che possono causar…
Changing commuters’ mobility behaviors of university campuses: environmental and energy comparisons
2021
Governments are required to take proper measures to promote the use of electric and hybrid vehicles and, more generally, to push people towards sweeter modalities including walking and biking. To reach such tight and challenging goals, local institutions should be deeply involved, and universities among them. The promotion of sustainable mobility practices among commuter students must be considered indeed an effective contribution to facilitating the transition towards greener cities. On purpose, students of the University of Palermo that daily commute from their residences to the campus are considered here. These commuters, in fact, mainly adopt traditional polluting transportation means. …
Hot spots and gluon field fluctuations as causes of eccentricity in small systems
2021
We calculate eccentricities in high energy proton-nucleus collisions, by calculating correlation functions of the energy density field of the Glasma immediately after the collision event at proper time tau = 0. We separately consider the effects of color charge and geometrical hot spot fluctuations, analytically performing the averages over both in a dilute-dense limit. We show that geometric fluctuations of hot spots inside the proton are the dominant source of eccentricity whereas color charge fluctuations only give a negligible correction. The size and number of hot spots are the most important parameters characterizing the eccentricities.
Azimuthal harmonics of color fields in a high energy nucleus
2015
Recent experimental results have revealed a surprisingly rich structure of multiparticle azimuthal correlations in high energy proton-nucleus collisions. Final state collective effects can be responsible for many of the observed effects, but it has recently been argued that a part of these correlations are present already in the wavefunctions of the colliding particles. We evaluate the momentum space 2-particle cumulant azimuthal anisotropy coefficients v_n{2}, n=2,3,4 from fundamental representation Wilson line distributions describing the high energy nucleus. These would correspond to the flow coefficients in very forward proton nucleus scattering. We find significant differences beteen W…
Multi-particle azimuthal correlations in p-Pb and Pb-Pb collisions at the CERN Large Hadron Collider
2014
Measurements of multi-particle azimuthal correlations (cumulants) for charged particles in p-Pb and Pb-Pb collisions are presented. They help address the question of whether there is evidence for global, flow-like, azimuthal correlations in the p-Pb system. Comparisons are made to measurements from the larger Pb-Pb system, where such evidence is established. In particular, the second harmonic two-particle cumulants are found to decrease with multiplicity, characteristic of a dominance of few-particle correlations in p-Pb collisions. However, when a $|\Delta \eta|$ gap is placed to suppress such correlations, the two-particle cumulants begin to rise at high-multiplicity, indicating the prese…
