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 "on the operating unit size of load store architectures"):
  Abstract: We introduce a strict version of the concept of a load/store instruction set architecture in the setting of Maurer machines. We take the view that transformations on the states of a Maurer machine are achieved by applying threads as considered in thread algebra to the Maurer machine. We study how the transformations on the states of the main memory of a strict load/store instruction set architecture that can be achieved by applying threads depend on the operating unit size, the cardinality of the instruction set and the maximal number of states of the threads.
