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: "abstraction representation theory for heterotic physical computing"
  Abstract: We give a rigorous framework for the interaction of physical computing devices with abstract computation. Device and program are mediated by the non-logical representation relation; we give the con...

Connected through hyperedge HE-1 (induced by source paper "defining and surveying wireless link virtualization and wireless network virtualization"):
