human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "identifying independencies in causal graphs with feedback"
  Abstract: We show that the d -separation criterion constitutes a valid test for conditional independence relationships that are induced by feedback systems involving discrete variables.

Connected through hyperedge HE-1 (induced by source paper "exact topology reconstruction of radial dynamical systems with applications to distribution system of the power grid"):
  with members:
    - "feeder topology identification"

Connected through hyperedge HE-2 (induced by source paper "discovering cyclic causal models with latent variables a general sat based procedure"):
  with members:
    - "bayesian networks from the point of view of chain graphs"
    - "directed cyclic graphical representations of feedback models"
    - "incorporating causal prior knowledge as path constraints in bayesian networks and maximal ancestral graphs"
    - "on deducing conditional independence from d separation in causal graphs with feedback"

Connected through hyperedge HE-3 (induced by source paper "asymmetric separation for local independence graphs"):
  with members:
    - "causal networks semantics and expressiveness"
    - "directed cyclic graphical representations of feedback models"
    - "continuous time bayesian networks"
    - "learning continuous time bayesian networks"
