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 "biologically inspired process calculi petri nets and membrane computing"):
  Abstract: This volume represents the proceedings of the 5th Workshop on Membrane Computing and Biologically Inspired Process Calculi (MeCBIC 2011), held together with the 12th International Conference on Membrane Computing on 23rd August 2011 in Fontainebleau, France.

Includes members:
  Member "applying cegar to the petri net state equation":
    also connected through other hyperedges:
      (none)
  Member "stochastic calculus of wrapped compartments":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "quantitative aspects of programming languages and systems over the past 2 4 years and beyond")
  Member "hybrid calculus of wrapped compartments":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "modelling spatial interactions in the arbuscular mycorrhizal symbiosis using the calculus of wrapped compartments")
  Member "edge and node disjoint paths in p systems":
    also connected through other hyperedges:
      (none)
  Member "an abstraction theory for qualitative models of biological systems":
    also connected through other hyperedges:
      (none)
  Member "on the convergence of population protocols when population goes to infinity":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "population protocols with faulty interactions the impact of a leader")
