Regulating (and Self-regulating) the Sharing Economy in Europe: An Overview
2018
The article describes the main legal challenges for regulating the sharing (or collaborative) economy in Europe and explains how the existing body of EU law applies to these new business models. In the last part, it makes a few brief comments on the need for future regulation.
Modeling of the Shear Connection Capacity of Hybrid Steel Trussed Composite Beams
2019
Hybrid Steel Trussed Composite Beams represent a technical solution in use in numerous countries since many years. They are able to join the advantages of prefabrication with those of cast in place structures: they are easy to manufacture, fast to realize, monolithic and with no need of formwork. The behavior of these beams has been recently topic of discussion in the scientific community because the knowledge both related to the reinforced concrete structures and that of composite constructions cannot be straightforwardly extended to this typology, which is intermediate between one and another technology. This paper provides a contribution towards a better understanding of the mechanism of…
Shell-model study of the 4th- and 6th-forbidden β -decay branches of 48-Ca
2014
The highly forbidden β− decay of 48Ca is reexamined by performing shell-model calculations with the GXPF1A effective interaction. We examine the three available decay branches to the lowest 6+, 5+, and 4+ states of 48Sc, and extract a theoretical half-life of T β 1/2 = 5.2+1.7 −1.3 × 1020 g−2 A yr for the β− decay, where gA is the value of the axial-vector coupling constant. The current half-life estimate suggests stronger competition between the single-β-decay and double-β-decay branches of 48Ca than previously expected on theoretical grounds. peerReviewed
Testing refined shell-model interactions in the sd shell: Coulomb excitation of 26Na
2015
Background: Shell-model calculations crucially depend on the residual interaction used to approximate the nucleon-nucleon interaction. Recent improvements to the empirical universal sd interaction (USD) describing nuclei within the sd shell yielded two new interactions—USDA and USDB—causing changes in the theoretical description of these nuclei. Purpose: Transitionmatrix elements between excited states provide an excellent probe to examine the underlying shell structure. These observables provide a stringent test for the newly derived interactions. The nucleus 26Na with 7 valence neutrons and 3 valence protons outside the doubly-magic 16O core is used as a test case. Method: A radioactive b…

Report on models and guidelines for the collaborative design, development and delivery of SLPs
2021
This document refers to deliverable 6.3 on the development of models and guidelines for the collaborative development and delivery of short learning programs and related mobility. Originally started with an introductory document, based on experience and expertise with joint Erasmus Mundus programmes, the Networked Curriculum Project (NETCU) and the work on the EADTU Mobility Matrix, this document builds further on the experience of the pilots in the ESLP project (WP6) and from other work packages, referring in particular to the comprehensive SLP design guidelines that have been developed (WP4). nonPeerReviewed
Analysis of parametric uncertainty in a shot noise model
2005
All model calibrations are subject to uncertainty. Even when an optimization procedure is used, the specific calibration period strongly influences the parameter values and causes uncertainty in streamflow prediction. The present paper aims to study the influence that the dimension and the position of the sampling period have on the uncertainty of the response of a daily conceptual shot noise model. The simulations have been conducted using continuous daily series of discharges recorded for 76 years on the river basin of Oreto (Palermo, Italy). Many continuous sub-series for simulations have been obtained from the historical series available. In the first place many model calibrations have …
A comprehensive guide to the physics and usage of PYTHIA 8.3
2022
This manual describes the PYTHIA 8.3 event generator, the most recent version of an evolving physics tool used to answer fundamental questions in particle physics. The program is most often used to generate high-energy-physics collision "events", i.e. sets of particles produced in association with the collision of two incoming high-energy particles, but has several uses beyond that. The guiding philosophy is to produce and reproduce properties of experimentally obtained collisions as accurately as possible. The program includes a wide ranges of reactions within and beyond the Standard Model, and extending to heavy ion physics. Emphasis is put on phenomena where strong interactions play a ma…
Deep-learning based reconstruction of the shower maximum X max using the water-Cherenkov detectors of the Pierre Auger Observatory
2021
The atmospheric depth of the air shower maximum $X_{\mathrm{max}}$ is an observable commonly used for the determination of the nuclear mass composition of ultra-high energy cosmic rays. Direct measurements of $X_{\mathrm{max}}$ are performed using observations of the longitudinal shower development with fluorescence telescopes. At the same time, several methods have been proposed for an indirect estimation of $X_{\mathrm{max}}$ from the characteristics of the shower particles registered with surface detector arrays. In this paper, we present a deep neural network (DNN) for the estimation of $X_{\mathrm{max}}$. The reconstruction relies on the signals induced by shower particles in the groun…
