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: "z checker a framework for assessing lossy compression of scientific data"
  Abstract: Because of the vast volume of data being produced by today’s scientific simulations and experiments, lossy data compressor allowing user-controlled loss of accuracy during the compression is a rele...

Connected through hyperedge HE-1 (induced by source paper "optimizing lossy compression rate distortion from automatic online selection between sz and zfp"):
  with members:
    - "significantly improving lossy compression for scientific data sets based on multidimensional prediction and error controlled quantization"
    - "on the scalability of data reduction techniques in current and upcoming hpc systems from an application perspective"
    - "exploration of pattern matching techniques for lossy compression on cosmology simulation data sets"
    - "in depth exploration of single snapshot lossy compression techniques for n body simulations"

Connected through hyperedge HE-2 (induced by source paper "in depth exploration of single snapshot lossy compression techniques for n body simulations"):
  with members:
    - "significantly improving lossy compression for scientific data sets based on multidimensional prediction and error controlled quantization"
    - "exploration of pattern matching techniques for lossy compression on cosmology simulation data sets"
