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 "covariance evolution for spatially mt fuji coupled ldpc codes"):
  Abstract: A spatially `Mt. Fuji' coupled low-density parity check ensemble is a modified version of the original spatially coupled low-density parity check ensemble. It is known that it has almost the same decoding error probability as and requires less number of iterations than the original ensemble in the waterfall region if we appropriately choose a parameter $\alpha$. In previous studies, a system of differential equations called covariance evolution is derived to analyze the waterfall performance of the original ensemble. In this paper, we modify it for the spatially `Mt. Fuji' coupled low-density parity check ensemble. Then, we analyze the waterfall performance.
