Strongly coupled coherent phonons in single-layer MoS
C. Trovatello, H. P. C. Miranda, A. Molina-Sánchez +15
We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution (20fs) which is ideally suited to trigger and de…
Augmented Replay Memory in Reinforcement Learning With Continuous Control
Mirza Ramicic, Andrea Bonarini
Online reinforcement learning agents are currently able to process an increasing amount of data by converting it into a higher order value functions. This expansion of the informat…
Federated Learning with Cooperating Devices: A Consensus Approach for Massive IoT Networks
Stefano Savazzi, Monica Nicoli, Vittorio Rampa
Federated learning (FL) is emerging as a new paradigm to train machine learning models in distributed systems. Rather than sharing, and disclosing, the training dataset with the se…
Non-Orthogonal eMBB-URLLC Radio Access for Cloud Radio Access Networks with Analog Fronthauling
Andrea Matera, Rahif Kassab, Osvaldo Simeone +1
This paper considers the coexistence of Ultra Reliable Low Latency Communications (URLLC) and enhanced Mobile BroadBand (eMBB) services in the uplink of Cloud Radio Access Network…
Drifts and Shifts: Characterizing the Evolution of Users Interests on Reddit
Carlo Michele Valensise, Matteo Cinelli, Alessandro Galeazzi +1
Selective exposure is the main driver for the economy of attention when consuming online content. We select information adhering to our system of beliefs and ignore dissenting info…
Integral representation of local left--invariant functionals in Carnot groups
Alberto Maione, Eugenio Vecchi
The aim of this note is to prove a representation theorem for left--invariant functionals in Carnot groups. As a direct consequence, we can also provide a -convergence result fo…
IsoGeometric Approximations for Electromagnetic Problems in Axisymmetric Domains
Abele Simona, Luca Bonaventura, Carlo de Falco +1
We propose a numerical method for the solution of electromagnetic problems on axisymmetric domains, based on a combination of a spectral Fourier approximation in the azimuthal dire…
Asymptotic behaviours in Fractional Orlicz-Sobolev spaces on Carnot groups
Marco Capolli, Alberto Maione, Ariel Martin Salort +1
In this article we define a class of fractional Orlicz-Sobolev spaces on Carnot groups and, in the spirit of the celebrated results of Bourgain-Brezis-Mironescu and of Maz'ya-Shapo…
NuSTAR/XMM-Newton monitoring of the Seyfert 1 galaxy HE 1143-1810. Testing the two-corona scenario
F. Ursini, P. -O. Petrucci, S. Bianchi +11
We test the two-corona accretion scenario for active galactic nuclei in the case of the `bare' Seyfert 1 galaxy HE 1143-1810. We perform a detailed study of the broad-band UV--X-ra…
Learning patient-specific parameters for a diffuse interface glioblastoma model from neuroimaging data
Abramo Agosti, Pasquale Ciarletta, Harald Garcke +1
Parameters in mathematical models for glioblastoma multiforme (GBM) tumour growth are highly patient specific. Here we aim to estimate parameters in a Cahn-Hilliard type diffuse in…
Robust Bang-Off-Bang Low-Thrust Guidance Using Model Predictive Static Programming
Yang Wang, Francesco Topputo
Model Predictive Static Programming (MPSP) was always used under the assumption of continuous control, which impedes it for applications with bang-off-bang control directly. In thi…
Coordination in Adversarial Sequential Team Games via Multi-Agent Deep Reinforcement Learning
Andrea Celli, Marco Ciccone, Raffaele Bongo +1
Many real-world applications involve teams of agents that have to coordinate their actions to reach a common goal against potential adversaries. This paper focuses on zero-sum game…
Quantum statistical signature of symmetry breaking
Stefano Longhi
In multiparticle quantum interference, bosons show rather generally the tendency to bunch together, while fermions can not. This behavior, which is rooted in the different statisti…
Tailored elastic surface to body wave Umklapp conversion
Gregory J. Chaplain, Jacopo M. De Ponti, Andrea Colombi +7
Elastic waves guided along surfaces dominate applications in geophysics, ultrasonic inspection, mechanical vibration, and surface acoustic wave devices; precise manipulation of sur…
A parallel-GPU code for asteroid aggregation problems with angular particles
F. Ferrari, M. Lavagna, E. Blazquez
The paper presents a numerical implementation of the gravitational N-body problem with contact interactions between non-spherically shaped bodies. The work builds up on a previous…
Nonzero positive solutions of elliptic systems with gradient dependence and functional BCs
Stefano Biagi, Alessandro Calamai, Gennaro Infante
We discuss, by topological methods, the solvability of systems of second-order elliptic differential equations subject to functional boundary conditions under the presence of gradi…
A high-order discontinuous Galerkin method for nonlinear sound waves
Paola. F. Antonietti, Ilario Mazzieri, Markus Muhr +2
We propose a high-order discontinuous Galerkin scheme for nonlinear acoustic waves on polytopic meshes. To model sound propagation with and without losses, we use Westervelt's nonl…
