human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "on approximating gaussian relay networks by deterministic networks"):
  Abstract: We examine the extent to which Gaussian relay networks can be approximated by deterministic networks, and present two results, one negative and one positive. #R##N#The gap between the capacities of a Gaussian relay network and a corresponding linear deterministic network can be unbounded. The key reasons are that the linear deterministic model fails to capture the phase of received signals, and there is a loss in signal strength in the reduction to a linear deterministic network. #R##N#On the positive side, Gaussian relay networks are indeed well approximated by certain discrete superposition networks, where the inputs and outputs to the channels are discrete, and channel gains are signed integers. #R##N#As a corollary, MIMO channels cannot be approximated by the linear deterministic model but can be by the discrete superposition model.
