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 "optimal exact repair strategy for the parity nodes of the k 2 k zigzag code"):
  Abstract: In this paper, we reinterprets the $(k+2,k)$ Zigzag code in coding matrix and then propose an optimal exact repair strategy for its parity nodes, whose repair disk I/O approaches a lower bound derived in this paper.

Includes members:
  Member "a framework of constructions of minimal storage regenerating codes with the optimal access update property":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a systematic construction of mds codes with small sub packetization level and near optimal repair bandwidth")
  Member "mdr codes a new class of raid 6 codes with optimal rebuilding and encoding":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a generic transformation to enable optimal repair in mds codes for distributed storage systems")
  Member "zigzag codes mds array codes with optimal rebuilding":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "enabling optimal access and error correction for the repair of reed solomon codes")
  Member "repair optimal erasure codes through hadamard designs":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "convertible codes efficient conversion of coded data in distributed storage")
  Member "on codes for optimal rebuilding access":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "a systematic construction of mds codes with small sub packetization level and near optimal repair bandwidth")
  Member "a survey on network codes for distributed storage":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "a combinatorial view of the service rates of codes problem its equivalence to fractional matching and its connection with batch codes")
