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: "robust gaussian joint source channel coding under the near zero bandwidth regime"
  Abstract: Minimum power required to achieve a distortion-noise profile, i.e., a function indicating the maximum allowed distortion value for each noise level, is studied for the transmission of Gaussian sources over Gaussian channels under a regime of bandwidth approaching zero. A simple but instrumental lower bound to the minimum required power for a given profile is presented. For an upper bound, a dirty-paper based coding scheme is proposed and its power-distortion tradeoff is analyzed. Finally, upper and lower bounds to the minimum power is analyzed and compared for specific distortion-noise profiles, namely rational profiles with order one and two.

Connected through hyperedge HE-1 (induced by source paper "robust gaussian joint source channel coding with a staircase distortion noise profile"):
  with members:
    - "minimum energy for gaussian joint source channel coding with a square law distortion noise profile"
    - "the porosity of additive noise sequences"
    - "communication over individual channels"
    - "interference channels with arbitrarily correlated sources"
