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: "on the cross correlation of a p ary m sequence and its decimated sequences by d frac p n 1 p k 1 frac p n 1 2"
  Abstract: In this paper, for an odd prime $p$ such that $p\equiv 3\bmod 4$, odd $n$, and $d=(p^n+1)/(p^k+1)+(p^n-1)/2$ with $k|n$, the value distribution of the exponential sum $S(a,b)$ is calculated as $a$ and $b$ run through $\mathbb{F}_{p^n}$. The sequence family $\mathcal{G}$ in which each sequence has the period of $N=p^n-1$ is also constructed. The family size of $\mathcal{G}$ is $p^n$ and the correlation magnitude is roughly upper bounded by $(p^k+1)\sqrt{N}/2$. The weight distribution of the relevant cyclic code $\mathcal{C}$ over $\mathbb{F}_p$ with the length $N$ and the dimension ${\rm dim}_{\mathbb{F}_p}\mathcal{C}=2n$ is also derived. Our result includes the case in \cite{Xia} as a special case.

Connected through hyperedge HE-1 (induced by source paper "some new results on the cross correlation of m sequences"):
