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 "the power of priority channel systems"):
  Abstract: We introduce Priority Channel Systems, a new class of channel systems where#N#messages carry a numeric priority and where higher-priority messages can#N#supersede lower-priority messages preceding them in the fifo communication#N#buffers. The decidability of safety and inevitability properties is shown via#N#the introduction of a priority embedding, a well-quasi-ordering that has not#N#previously been used in well-structured systems. We then show how Priority#N#Channel Systems can compute Fast-Growing functions and prove that the#N#aforementioned verification problems are#N#$\mathbf{F}_{\varepsilon_{0}}$-complete.
