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 "refinement of the sphere packing bound asymmetric channels"):
  Abstract: We provide a refinement of the sphere-packing bound for constant composition codes over asymmetric discrete memoryless channels that improves the pre-factor in front of the exponential term. The order of our pre-factor is $\Omega(N^{-1/2(1+\epsilon + \rho_{R}^{\ast})})$ for any $\epsilon >0$, where $\rho_{R}^{\ast}$ is the maximum absolute-value subdifferential of the sphere-packing exponent at rate $R$ and $N$ is the blocklength.

Includes members:
  Member "refinement of the random coding bound":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "second order asymptotics of sequential hypothesis testing")
  Member "finite dimensional infinite constellations":
    also connected through other hyperedges:
