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 "well rounded lattices via polynomials"):
  Abstract: Well-rounded lattices have been a topic of recent studies with applications in wiretap channels and in cryptography. A lattice of full rank in Euclidean space is called well-rounded if its set of minimal vectors spans the whole space. In this paper, we investigate when lattices coming from polynomials with integer coefficients are well-rounded.

Includes members:
  Member "well rounded lattices for coset coding in mimo wiretap channels":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "well rounded lattices towards optimal coset codes for gaussian and fading wiretap channels")
  Member "well rounded lattices for reliability and security in rayleigh fading siso channels":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "well rounded lattices towards optimal coset codes for gaussian and fading wiretap channels")
  Member "on projections of arbitrary lattices":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a note on subortogonal lattices")
