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 "quorum sensing and verification in chemical reaction networks"):
  Abstract: Some species of bacteria exhibit quorum sensing, a phenomenon in which gene expression and resultant behavior undergo a phase change at some threshold population density. We show here that even very simple nanodevices, modeled as chemical reaction networks, can by a different mechanism also sense their own population densities and change their behaviors dramatically at certain thresholds. Moreover, the magnitudes of these thresholds can thwart attempts to use model checking, simulation, or approximation by differential equations to formally verify the behaviors of such nanodevices at realistic population densities. We show how formal theorem provers can successfully verify some such systems at sizes where other verification methods fail.

Includes members:
  Member "efficiency through uncertainty scalable formal synthesis for stochastic hybrid systems":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "stochy automated verification and synthesis of stochastic processes")
  Member "the computational power of population protocols":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "robust comparison in population protocols")
