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: "new inequalities of mill s ratio and its application to the inverse q function approximation"
  Abstract: In this paper, we investigate the Mill’s ratio estimation pr oblem and get two new inequalities. Compared to the well known results obtained by Gordon, they becomes tighter. Furthermore, we also discuss the inverse Q-function approximation problem and present some useful results on the inverse solution. Numerical results confirm the validness of our the oretical analysis. In addition, we also present a conjecture on the bounds of inverse solution on Q-function.
