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: "information energy and density for ad hoc sensor networks over correlated random fields large deviations analysis"
  Abstract: Using large deviations results that characterize the amount of information per node on a two-dimensional (2-D) lattice, asymptotic behavior of a sensor network deployed over a correlated random field for statistical inference is investigated. Under a 2-D hidden Gauss-Markov random field model with symmetric first order conditional autoregression, the behavior of the total information [nats] and energy efficiency [nats/J] defined as the ratio of total gathered information to the required energy is obtained as the coverage area, node density and energy vary.

Connected through hyperedge HE-1 (induced by source paper "energy scaling laws for distributed inference in random fusion networks"):

    - "detection of gauss markov random fields with nearest neighbor dependency"
    - "sensor configuration and activation for field detection in large sensor arrays"
