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: "non uniform cellular automata and distributions of rules"
  Abstract: In this paper we study $\nu$-CA on one-dimensional lattice defined over a finite set of local rules. The main goal is to determine how the local rules can be mixed to ensure the produced $\nu$-CA has some properties. In a first part, we give some background for the study of $\nu$-CA. Then surjectivity and injectivity are studied using a variant of DeBruijn graphs. The next part is dedicated to the number-conserving property.

Connected through hyperedge HE-1 (induced by source paper "a survey of cellular automata types dynamics non uniformity and applications"):
  with members:
    - "reversibility of d state finite cellular automata"
    - "non uniform cellular automata classes dynamics and decidability"
