"Table 5" of "Suppression of $\Lambda(1520)$ resonance production in central Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV"
2018
$\Lambda$(1520) (sum of particle and anti-particle states) to $\Lambda$ (defined as 2 $\Lambda$) $p_{\rm T}$-integrated yield ratio at midrapidity as a function of $\langle {\rm d}N_{\rm ch}/{\rm d}\eta \rangle^{1/3}$. The uncertainty 'syst,uncorrelated' indicates the systematic uncertainty after removing the contributions common to all centrality classes
Variable Neighborhood Search for the Vertex Separation Problem
2012
The vertex separation problem belongs to a family of optimization problems in which the objective is to nd the best separator of vertices or edges in a generic graph. This optimization problem is strongly related to other well-known graph problems; such as the Path-Width, the Node Search Number or the Interval Thickness, among others. All of these optimization problems are NP-hard and have practical applications in VLSI, computer language compiler design or graph drawing. Up to know, they have been generally tackled with exact approaches, presenting polynomial-time algorithms to obtain the optimal solution for speci c types of graphs. However, in spite of their practical applications, these…
Visibility in mediated borderscapes : The hunger strike of asylum seekers as an embodiment of border violence
2018
In 2012, two Afghan asylum seekers camped outside the Parliament building in Helsinki during a hunger strike that lasted for 72 days. Although the protest was very visible in the city space, the mainstream media and most politicians ignored it. This paper analyzes the protest and its mediation through the concepts of borderscape and visibility. Using methods of visual and discourse analysis, we examine the ways in which the hunger strike protest – and its mediation – negotiate the (in)visibility of borders. We show how the city can be a site for both policing and for politicizing asylum issues. In particular, we focus on the ways in which protesting asylum seekers embody borders and border …
NEIGHBORHOOD EFFECTS IN SPATIAL HOUSING VALUE MODELS. THE CASE OF THE METROPOLITAN AREA OF PARIS (1999)
2009
In hedonic housing models, the spatial dimension of housing values are traditionally processed by the impact of neighborhood variables and accessibility variables. In this paper we show that spatial effects might remain once neighborhood effects and accessibility have been controlled for. We notably stress on three sides of neighborhood effects: social capital, social status and social externalities and consider the accessibility to the primary economic center as describing the urban spatial trend. Using spatial econometrics specifications of the hedonic equation, we estimate whether spatial effects impact the housing values. Our empirical case concerns the Metropolitan Area (MA) of Paris i…
