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: "independence and concurrent separation logic"
  Abstract: A compositional Petri net-based semantics is given to a simple language#N#allowing pointer manipulation and parallelism. The model is then applied to#N#give a notion of validity to the judgements made by concurrent separation logic#N#that emphasizes the process-environment duality inherent in such rely-guarantee#N#reasoning. Soundness of the rules of concurrent separation logic with respect#N#to this definition of validity is shown. The independence information retained#N#by the Petri net model is then exploited to characterize the independence of#N#parallel processes enforced by the logic. This is shown to permit a refinement#N#operation capable of changing the granularity of atomic actions.
