Sensor operating point calibration and monitoring of the ALICE Inner Tracking System during LHC Run 3
D. Agguiaro, G. Aglieri Rinella, L. Aglietta +285
The new Inner Tracking System (ITS2) of the ALICE experiment began operation in 2021 with the start of LHC Run 3. Compared to its predecessor, ITS2 offers substantial improvements…
Pairwise and high-order dependencies in the cryptocurrency trading network
Tomas Scagliarini, Giuseppe Pappalardo, Alessio Emanuele Biondo +3
In this paper we analyse the effects of information flows in cryptocurrency markets. We first define a cryptocurrency trading network, i.e. the network made using cryptocurrencies…
Blockchain Inefficiency in the Bitcoin Peers Network
Giuseppe Pappalardo, T. Di Matteo, Guido Caldarelli +1
We investigate Bitcoin network monitoring the dynamics of blocks and transactions. We unveil that 43\% of the transactions are still not included in the Blockchain after 1h from th…
The Accounting Network: how financial institutions react to systemic crisis
Andrea Flori, Giuseppe Pappalardo, Michelangelo Puliga +2
The role of Network Theory in the study of the financial crisis has been widely spotted in the latest years. It has been shown how the network topology and the dynamics running on…
INFN What Next: Ultra-relativistic Heavy-Ion Collisions
A. Dainese, E. Scomparin, G. Usai +138
This document was prepared by the community that is active in Italy, within INFN (Istituto Nazionale di Fisica Nucleare), in the field of ultra-relativistic heavy-ion collisions. T…
Simplified firefly algorithm for 2D image key-points search
Christian Napoli, Giuseppe Pappalardo, Emiliano Tramontana +3
In order to identify an object, human eyes firstly search the field of view for points or areas which have particular properties. These properties are used to recognise an image or…
An agent-driven semantical identifier using radial basis neural networks and reinforcement learning
Christian Napoli, Giuseppe Pappalardo, Emiliano Tramontana
Due to the huge availability of documents in digital form, and the deception possibility raise bound to the essence of digital documents and the way they are spread, the authorship…
Improving files availability for BitTorrent using a diffusion model
Christian Napoli, Giuseppe Pappalardo, Emiliano Tramontana
The BitTorrent mechanism effectively spreads file fragments by copying the rarest fragments first. We propose to apply a mathematical model for the diffusion of fragments on a P2P…
A hybrid neuro--wavelet predictor for QoS control and stability
Christian Napoli, Giuseppe Pappalardo, Emiliano Tramontana
For distributed systems to properly react to peaks of requests, their adaptation activities would benefit from the estimation of the amount of requests. This paper proposes a solut…
A Cascade Neural Network Architecture investigating Surface Plasmon Polaritons propagation for thin metals in OpenMP
Francesco Bonanno, Giacomo Capizzi, Grazia Lo Sciuto +3
Surface plasmon polaritons (SPPs) confined along metal-dielectric interface have attracted a relevant interest in the area of ultracompact photonic circuits, photovoltaic devices a…
Using Modularity Metrics to assist Move Method Refactoring of Large System
Christian Napoli, Giuseppe Pappalardo, Emiliano Tramontana
For large software systems, refactoring activities can be a challenging task, since for keeping component complexity under control the overall architecture as well as many details…
ALICE EMCal Physics Performance Report
Rene Bellwied
The ALICE detector at the LHC (A Large Ion Collider Experiment) will carry out comprehensive measurements of high energy nucleus-nucleus collisions, in order to study QCD matter un…
Strangeness enhancements at central rapidity in 40 A GeV/c Pb-Pb collisions
The NA57 Collaboration, F. Antinori
Results are presented on neutral kaon, hyperon and antihyperon production in Pb-Pb and p-Be interactions at 40 GeV/c per nucleon. The enhancement pattern follows the same hierarchy…
Performance of prototypes for the ALICE electromagnetic calorimeter
The ALICE EMCal group
The performance of prototypes for the ALICE electromagnetic sampling calorimeter has been studied in test beam measurements at FNAL and CERN. A array of final design mod…
Expansion dynamics of Pb-Pb collisions at 40 A GeV/c viewed by negatively charged hadrons
The NA57 Collaboration
In this paper we present results on transverse mass spectra and Hanbury-Brown and Twiss correlation functions of negatively charged hadrons, which are expected to be mostly negativ…
Transverse dynamics of Pb-Pb collisions at 40 A GeV/c viewed by strange hadrons
The NA57 Collaboration
The transverse mass spectra of K0s, Lambda, Xi and Omega particles produced in Pb-Pb collisions at 40 A GeV/c have been studied for a sample of events corresponding to the most cen…
