background: we conducted a comprehensive bibliometrics analysis to calculate the h, g, m, a and r indicators for all iranian biomedical research centers (ibrcs) from the output of isi web of science (wos) and scopus between 1991 and 2010. we compared the research performance of the research centers according to these indicators.   methods : this was a cross-sectional and descriptive-analytical ...

let $g$ be a graph and let $m_{ij}(g)$, $i,jge 1$, be the number of edges $uv$ of $g$ such that ${d_v(g), d_u(g)} = {i,j}$. the {em $m$-polynomial} of $g$ is introduced with $displaystyle{m(g;x,y) = sum_{ile j} m_{ij}(g)x^iy^j}$. it is shown that degree-based topological indices can be routinely computed from the polynomial, thus reducing the problem of their determination in each particular ca...

topological indices are numerical parameters of a graph which characterize its topology. inthis paper the pi, szeged and zagreb group indices of the tetrameric 1,3–adamantane arecomputed.

in theoretical chemistry, molecular structure descriptors are used to compute properties of chemical compounds. among them wiener, szeged and detour indices play significant roles in anticipating chemical phenomena. in the present paper, we study these topological indices with respect to their difference number.

The caste issue dominates a large part of India’s social and political life. Caste shapes Indians’ identities, and strong tensions exist between castes. This paper evaluates how caste-based comparisons may be exacerbated in such a conflictual context. Using subjective well-being data from an original panel survey, together with a national representative survey on expenditure, we find that both ...

Cost optimization is an important criterion in technology deployment for developing regions. While IEEE 802.11-based long-distance networks may provide a cost-effective option to connect remote villages, planning such a network to cover the villages in a given region can be a non-trivial task. This is especially so since the antenna tower cost is the dominant cost in such scenarios. In this the...
