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 "a general theory of computational scalability based on rational functions"):
  Abstract: The universal scalability law of computational capacity is a rational function Cp = P (p)=Q(p) with P (p) a linear polynomial and Q(p) a second-degree polynomial in the number of physical processors p, that has been long used for statistical modeling and prediction of computer system performance. We prove that Cp is equivalent to the synchronous throughput bound for a machinerepairman with state-dependent service rate. Simpler rational functions, such as Amdahl’s law and Gustafson speedup, are corollaries of this queue-theoretic bound. Cp is further shown to be both necessary and sucient for modeling all practical characteristics of computational scalability.
