"Table 18" of "Inclusive $\Upsilon$ production in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 8.16 TeV"
2020
Ratio of $\Upsilon$(3S) to $\Upsilon$(1S) $R_{\rm pPb}$ at $\sqrt{s_{\rm NN}}$ = 8.16 TeV as a function of $y_{\rm cms}$ .The first uncertainty is statistical, while the second is the systematic.
Specification and Implementation of Multicast Congestion Control Stair Protocol: Use Case with Multimedia Ubiquitous Networks
2008
Ubiquitous and efficient multicast data delivery service is essential to the success of large-scale group communication applications. In this framework, congestion control through ubiquitous networks is a hot topic for multicast real time protocols. In this paper, authors present specification and implementation of simulate TCP's AIMD with rate-based (STAIR), a multicast congestion control mechanism. Authors have enhanced this approach because they have modeled it using Unified Modeling Language with real time extensions (UML-RT) as a formal specification tool. More to the point point, they introduce a multimedia ubiquitous network which they have used as a reference model to promote their …
Unbounded derivations and *-automorphisms groups of Banach quasi *-algebras
2018
This paper is devoted to the study of unbounded derivations on Banach quasi *-algebras with a particular emphasis to the case when they are infinitesimal generators of one parameter automorphisms groups. Both of them, derivations and automorphisms are considered in a weak sense; i.e., with the use of a certain families of bounded sesquilinear forms. Conditions for a weak *-derivation to be the generator of a *-automorphisms group are given.
RIGENERAZIONE DI CITTADINE RURALI MEDIANTE IL TURISMO SOSTENIBILE: UN MODELLO DI VALUTAZIONE
2017
Rehabilitation of ancient towns poses special questions because of the existing complex physical and social ties that can be properly integrated in decisions on sustainable urban planning by multi-criteria evaluations. This work proposes a description model aiding actions and decisions for the rehabilitation of historic centres through tourism development in Sicilian hinterland areas. The decision problem concerns the town of Cianciana, which in recent years has been appreciated by strangers who stay on this town to live with the local inhabitants. Despite this international attention, at present, the town is undergoing local’s depopulation, gentrification and economic crisis. The proposed …

Splines Computation by Subdivision
2015
In this chapter, fast stable algorithms are presented, which compute splines’ values at dyadic and triadic rational points starting from their samples at integer grid points. The algorithms are implemented by the causal-anticausal recursive filtering of initial data samples, which is followed by iterated application of FIR filters. Extension of the algorithms to the multidimensional case is straightforward. A natural application of the presented subdivision algorithms is for upsampling of signals and images. A few upsampling examples are provided.
Non-periodic Discrete Splines
2015
Discrete Splines with different spans were introduced in Sect. 3.3.1. This chapter focuses on a special case of discrete splines whose spans are powers of 2. These splines are discussed in more detail. The Zak transform provides an integral representation of such splines. Discrete exponential splines are introduced. Generators of the discrete-spline spaces are described whose properties are similar to properties of polynomial-spline spaces generators. Interpolating discrete splines provide efficient tools for upsampling 1D and 2D signals. An algorithm for explicit computation of discrete splines is described.
Non-periodic Discrete-Spline Wavelets
2015
This chapter describes wavelet analysis in the spaces of discrete splines whose spans are powers of 2. This wavelet analysis is similar to wavelet analysis in the polynomial-spline spaces. The transforms are based on relations between exponential discrete splines from different resolution scales. Generators of discrete-spline wavelet spaces are described. The discrete-spline wavelet transforms generate wavelet transforms in signal space. Practically, wavelet transforms of signals are implemented by multirate filtering of signals by two-channel filter banks with the downsampling factor 2 (critically sampled filter banks). The filtering implementation is accelerated by switching to the polyph…
A reconsideration of the link between vertical externality and managerial incentives
2018
Previous research revealed that the strategic role of delegation contracts disappears if two quantity†setting firms outsource input production to a monopolistic supplier. I show that this role is restored if the assumption of a downstream duopoly is relaxed. Thus, delegation contracts allow downstream profit†maximizing owners to commit their firms to a behavior that differs from their preferences. This behavior varies nonmonotonically with the number of firms in the downstream market. Corresponding deviations from profit maximization are larger if the upstream monopolist makes a price precommitment. But little to no deviation occurs if the number of firms is large.
Upstream Product Market Regulations, ICT, R&D and Productivity
2013
Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus precisely try to estimate what are the specific impacts of these two channels and their shares in total impact as against alternative channels of investments in other forms of intangible capital such as improvements in skills, management and organization. For this, we specify an extended production function relating productivity explicitly to R&D and ICT capital as well as to upstream regulations, and two factor demand functions relating R&D a…
