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: "on the joint error and erasure decoding for irreducible polynomial remainder codes"
  Abstract: A general class of polynomial remainder codes is considered. Such codes are very flexible in rate and length and include Reed-Solomon codes as a special case. #R##N#As an extension of previous work, two joint error-and-erasure decoding approaches are proposed. In particular, both the decoding approaches by means of a fixed transform are treated in a way compatible with the error-only decoding. In the end, a collection of gcd-based decoding algorithm is obtained, some of which appear to be new even when specialized to Reed-Solomon codes.

Connected through hyperedge HE-1 (induced by source paper "error correction in polynomial remainder codes with non pairwise coprime moduli and robust chinese remainder theorem for polynomials"):
  with members:
    - "multi stage robust chinese remainder theorem"
    - "on polynomial remainder codes"
