José J. Ramasco, Vittoria Colizza, Pietro Panzarasa
2009 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
In all cases, a strong weighted rich-club effect is found.  ...  Such tendency is known as the weighted rich-club effect.  ...  A recently introduced measure called the weighted richclub coefficient [31] enables us to study whether and the extent to which the prominent elements of a system attract, control, and share among themselves  ...

Rich do not rise early: spatio-temporal patterns in the mobility networks of different socio-economic classes

Laura Lotero, Rafael G. Hurtado, Luis Mario Floría, Jesús Gómez-Gardeñes
2016 Royal Society Open Science  
We analyse the urban mobility in the cities of Medellín and Manizales (Colombia).  ...  Each city is represented by six mobility networks, each one encoding the origin-destination trips performed by a subset of the population corresponding to a particular socio-economic status.  ...  We thank Area Metropolitana del Valle de Aburrá in Medellín for the Origin-Destination Surveys Datasets.  ...

2021 Scientific Reports  
In this paper we provide a framework to quantify the substantial impact of the mobility restrictions.  ...  We introduce a percolation model mimicking mobility network disruption and find that node persistence in the percolation process is significantly correlated with the economic and demographic characteristics  ...  This effect can be explained by assuming a "rich club" structure 38 , where links corresponding to higher mobility flows are concentrated around core regions.  ...
