human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "distance distributions for real cellular networks"
  Abstract: This paper presents the general distribution for the#R##N#distance between a mobile user and any base station (BS). We#R##N#show that a random variable proportional to the distance squared#R##N#is Gamma distributed. In the case of the nearest BS, it can#R##N#be reduced to the well established result of the distance being#R##N#Rayleigh distributed. We validate our results using a random node#R##N#simulation and real Vodafone 3G network data, and go on to show#R##N#how the distribution is tractable by deriving the average aggregate#R##N#interference power.#R##N#I
