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: "new mds or near mds self dual codes over finite fields"
  Abstract: The study of MDS self-dual codes has attracted lots of attention in recent years. #R##N#There are many papers on determining existence of $q-$ary MDS self-dual codes for various lengths. #R##N#There are not existence of $q-$ary MDS self-dual codes of some lengths, even these lengths $< q$. #R##N#We generalize MDS Euclidean self-dual codes to near MDS Euclidean self-dual codes and near MDS isodual codes. #R##N#And we obtain many new near MDS isodual codes from extended negacyclic duadic codes and we obtain many new MDS Euclidean self-dual codes from MDS Euclidean self-dual codes. #R##N#We generalize MDS Hermitian self-dual codes to near MDS Hermitian self-dual codes. #R##N#We obtain near MDS Hermitian self-dual codes from extended negacyclic duadic codes and from MDS Hermitian self-dual codes.
