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: "modeling and information rates for synchronization error channels"
  Abstract: We propose a new channel model for channels with synchronization errors. Using this model, we give simple, non-trivial and, in some cases, tight lower bounds on the capacity for certain synchronization error channels.

Connected through hyperedge HE-1 (induced by source paper "on the capacity of channels with timing synchronization errors"):
  with members:
    - "achievable rates for channels with deletions and insertions"
    - "optimal coding for the deletion channel with small deletion probability"
    - "write channel model for bit patterned media recording"
    - "coding for high density recording on a 1 d granular magnetic medium"
    - "on the deletion channel with small deletion probability"
    - "novel bounds on the capacity of the binary deletion channel"

Connected through hyperedge HE-2 (induced by source paper "energy efficient communication over the unsynchronized gaussian diamond network"):
  with members:
    - "using superposition codebooks and partial decode and forward in low snr parallel relay networks"
    - "achievable rates for channels with deletions and insertions"
    - "energy efficient communication in the presence of synchronization errors"
    - "the approximate capacity of the gaussian n relay diamond network"
    - "asynchronous capacity per unit cost"
    - "on the deletion channel with small deletion probability"

Connected through hyperedge HE-3 (induced by source paper "achievable rates for channels with deletions and insertions"):
  with members:
    - "efficient file synchronization a distributed source coding approach"
    - "write channel model for bit patterned media recording"
    - "on the deletion channel with small deletion probability"
    - "novel bounds on the capacity of the binary deletion channel"
