We predicted the extreme values of ENSO index, Niño3.4 and Southern Oscillation Index (SOI) using value theory. Various diagnostic plots for assessing accuracy Generalized Pareto (GP) model fitted to index SOI are shown, all four support GP model. Because shape parameter was negative, had a finite upper limit. In contrast, that zero, therefore did not have limit, there is possibility significan...

let $g$ be a molecular graph with vertex set $v(g)$, $d_g(u, v)$ the topological distance between vertices $u$ and $v$ in $g$. the hosoya polynomial $h(g, x)$ of $g$ is a polynomial $sumlimits_{{u, v}subseteq v(g)}x^{d_g(u, v)}$ in variable $x$. in this paper, we obtain an explicit analytical expression for the expected value of the hosoya polynomial of a random benzenoid chain with $n$ hexagon...
