Characterizing Long-Running Political Phenomena on Social Media
Emre Calisir, Marco Brambilla
Social media provides many opportunities to monitor and evaluate political phenomena such as referendums and elections. In this study, we propose a set of approaches to analyze lon…
Surface measures and integration by parts formula on levels sets induced by functionals of the Brownian motion in
Stefano Bonaccorsi, Luciano Tubaro, Margherita Zanella
On the infinite dimensional space of continuous paths from to , , endowed with the Wiener measure , we construct a surface measure defined on l…
Anyonic symmetry, drifting potentials and non-Hermitian delocalization
S. Longhi, E. Pinotti
We consider wave dynamics for a Schrödinger equation with a non-Hermitian Hamiltonian satisfying the generalized (anyonic) parity-time symmetry $\mathcal{PT H}= \exp(…
Pump-Push-Probe for Ultrafast All-Optical Switching: The Case of a Nanographene Molecule
Giuseppe M. Paterno, Luca Moretti, Alex J. Barker +6
In the last two decades, the three-beams pump-push-probe (PPP) technique has become a well-established tool for investigating the multidimensional configurational space of a molecu…
Helium load on W-O coatings grown by pulsed laser deposition
R. Mateus, D. Dellasega, M. Passoni +4
W-O deposits with complex morphologies and significant He contents will growth on the surface of plasma facing components exposed to He discharges. To mimic the re/co-deposition pr…
On the existence of elastic minimizers for initially stressed materials
Davide Riccobelli, Abramo Agosti, Pasquale Ciarletta
A soft solid is said to be initially stressed if it is subjected to a state of internal stress in its unloaded reference configuration. Developing a sound mathematical framework to…
Systematic Parsing of X.509: Eradicating Security Issues with a Parse Tree
Alessandro Barenghi, Nicholas Mainardi, Gerardo Pelosi
X.509 certificate parsing and validation is a critical task which has shown consistent lack of effectiveness, with practical attacks being reported with a steady rate during the la…
Ultrafast THz probe of photo-induced polarons in lead-halide perovskites
Eugenio Cinquanta, Daniele Meggiolaro, Silvia G. Motti +8
We study the nature of photo-excited charge carriers in CsPbBr3 nanocrystal thin films by ultrafast optical pump - THz probe spectroscopy. We observe a deviation from a pure Drude…
Universal Frequency Dependence of the Hopping AC Conductance in p-Ge/GeSi Structures in the Integer Quantum Hall Effect Regime
I. L. Drichko, A. A. Dmitriev, V. A. Malysh +6
The hopping ac conductance, which is realized at the transverse conductance minima in the regime of the integer Hall effect, has been measured using a combination of acoustic and m…
HERMES: An ultra-wide band X and gamma-ray transient monitor on board a nano-satellite constellation
F. Fuschino, R. Campana, C. Labanti +49
The High Energy Modular Ensemble of Satellites (HERMES) project is aimed to realize a modular X/gamma-ray monitor for transient events, to be placed on-board of a CubeSat bus. This…
The enhanced X-ray Timing and Polarimetry mission - eXTP
ShuangNan Zhang, Andrea Santangelo, Marco Feroci +146
In this paper we present the enhanced X-ray Timing and Polarimetry mission - eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of…
Lagrangian diffusive reactor for detailed thermochemical computations of plasma flows
Stefano Boccelli, Federico Bariselli, Bruno Dias +1
The simulation of thermochemical nonequilibrium for the atomic and molecular energy level populations in plasma flows requires a comprehensive modeling of all the elementary collis…
Collective dynamics of evanescently coupled excitable lasers with saturable absorber
Marco Lamperti, Auro Perego
We present a numerical study of the collective dynamics in a population of coupled excitable lasers with saturable absorber. At variance with previous studies where real-valued (lo…
Probing one-dimensional topological phases in waveguide lattices with broken chiral symmetry
Stefano Longhi
One-dimensional lattices with chiral symmetry are known to possess quantized Zak phase and nontrivial topological phases. Here it is shown that quantized Zak phase and nontrivial e…
Quantum interference and exceptional points
Stefano Longhi
Exceptional points (EPs), i.e. branch point singularities of non-Hermitian Hamiltonians, are ubiquitous in optics. So far, the signatures of EPs have been mostly studied assuming c…
Photonic Flatband Laser
Stefano Longhi
Flatband photonic lattices, i.e. arrays of waveguides or resonators displaying a flat Bloch band, offer new routes for light trapping and distortion-free imaging. Here it is shown…
A Technical Survey on Statistical Modelling and Design Methods for Crowdsourcing Quality Control
Yuan Jin, Mark Carman, Ye Zhu +1
Online crowdsourcing provides a scalable and inexpensive means to collect knowledge (e.g. labels) about various types of data items (e.g. text, audio, video). However, it is also k…
Orbit Expandability of Automaton Semigroups and Groups
Daniele D'Angeli, Emanuele Rodaro, Jan Philipp Wächter
We introduce the notion of expandability in the context of automaton semigroups and groups: a word is k-expandable if one can append a suffix to it such that the size of the orbit…
On slice polyanalytic functions of a quaternionic variable
Daniel Alpay, Kamal Diki, Irene Sabadini
In this paper, we introduce the quaternionic slice polyanalytic functions and we prove some of their properties. Then, we apply the obtained results to begin the study of the quate…
Adversarial Autoencoders with Constant-Curvature Latent Manifolds
Daniele Grattarola, Lorenzo Livi, Cesare Alippi
Constant-curvature Riemannian manifolds (CCMs) have been shown to be ideal embedding spaces in many application domains, as their non-Euclidean geometry can naturally account for s…
Quantum Incompatibility Witnesses
Claudio Carmeli, Teiko Heinosaari, Alessandro Toigo
We demonstrate that quantum incompatibility can always be detected by means of a state discrimination task with partial intermediate information. This is done by showing that only…
On the supremal version of the Alt-Caffarelli minimization problem
