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 "l1 optimal splines for outlier rejection"):
  Abstract: In this article, we consider control theoretic splines with L 1 optimization for rejecting outliers in data. Control theoretic splines are either interpolating or smoothing splines, depending on a cost function with a constraint dened by linear dierential equations. Control

Includes members:
  Member "monotone smoothing splines using general linear systems":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "l 1 control theoretic smoothing splines")
  Member "sparse representations for packetized predictive networked control":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "optimal control of linear systems with limited control actions threshold based event triggered control")
  Member "compressive sampling for remote control systems":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "sparse packetized predictive control for networked control over erasure channels")
  Member "packetized predictive control for rate limited networks via sparse representation":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "sparse packetized predictive control for networked control over erasure channels")
