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 "sidon sequences and doubly periodic two dimensional synchronization patterns"):
  Abstract: Sidon sequences and their generalizations have found during the years and especially recently various applications in coding theory. One of the most important applications of these sequences is in the connection of synchronization patterns. A few constructions of two-dimensional synchronization patterns are based on these sequences. In this paper we present sufficient conditions that a two-dimensional synchronization pattern can be transformed into a Sidon sequence. We also present a new construction for Sidon sequences over an alphabet of size q(q-1), where q is a power of a prime.

Includes members:
  Member "codes in permutations and error correction for rank modulation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "optimal constant weight codes under l_1 metric")
  Member "sequence folding lattice tiling and multidimensional coding":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "simple and robust binary self location patterns")
