On the meaning of the h-index
نویسنده
چکیده
The h-index—defined as the value such that an individual has published at least h papers with at least h citations—has become a popular metric for assessing the citation impact of scientists. As already noted in the original work of Hirsch and as evidenced from data for a representative sample of 255 physicists, √ c scales as h, where c is the total number of citations for an individual. Thus √ c appears to be equivalent to the h-index. As a further check of this equivalence, the distribution of the ratio s ≡ √c/2h for this sample is sharply peaked about 1. The outliers in this distribution reveal fundamentally different kinds of individual publication records.

Let G be a connected simple (molecular) graph. The distance d(u, v) between two vertices u and v of G is equal to the length of a shortest path that connects u and v. In this paper we compute some distance based topological indices of H-Phenylenic nanotorus. At first we obtain an exact formula for the Wiener index. As application we calculate the Schultz index and modified Schultz index of this...
