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 "operations on automata with all states final"):
  Abstract: We study the complexity of basic regular operations on languages represented by incomplete deter-ministic or nondeterministic automata, in which all states are ﬁnal. Such languages are known tobe preﬁx-closed. We get tight bounds on both incomplete and nondeterministic state complexity ofcomplement, intersection, union, concatenation, star, and reversal on preﬁx-closed languages.
