    "abstract": "Growing network models with preferential attachment dependent on both age and\ndegree are proposed to simulate certain features of citation network noted in\n\\cite{red2}. In this directed network, a new node gets attached to an older\nnode with the probability $\\sim K(k)f(t)$ where the degree and age of the older\nnode are $k$ and $t$ respectively. Several functional forms of $K(k)$ and\n$f(t)$ have been considered. The desirable features of the citation network can\nbe reproduced with $K(k) \\sim k^{-\\beta}$ and $f(t) \\sim \\exp(\\alpha t)$ with\n$\\beta =2.0$ and $\\alpha = -0.2$ and with simple modifications in the growth\nscheme.",
