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 "scaled tree fractals do not strictly self assemble"):
  Abstract: In this paper, we show that any scaled-up version of any discrete self-similar {\it tree} fractal does not strictly self-assemble, at any temperature, in Winfree's abstract Tile Assembly Model.

Includes members:
  Member "intrinsic universality in tile self assembly requires cooperation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the program size complexity of self assembled paths")
  Member "approximate self assembly of the sierpinski triangle":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "hierarchical growth is necessary and sometimes sufficient to self assemble discrete self similar fractals")
  Member "strict self assembly of discrete sierpinski triangles":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "geometric tiles and powers and limitations of geometric hindrance in self assembly")
  Member "self assembly of the discrete sierpinski carpet and related fractals":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "compact error resilient self assembly of recursively defined patterns")
  Member "self assembly of discrete self similar fractals":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "deterministic 2 dimensional temperature 1 tile assembly systems cannot compute")
