The effective nonleptonic weak Hamiltonian is examined beyond the leading-logarithm approximation. In the AS=l, AC=1 part of the Hamiltonian no significant contribution is found. In the AS=l, AC=0 sector coefficients of the "penguin" operators depend strongly on added corrections. The momentum subtraction scheme has been used in the calculation. The independence of the result on the renormaliza...

Diatomic Hypothesis and Calculation of Condensation Force Author: Zeljko Prebeg Lermanova 12a, 10000 Zagreb, Croatia [email protected] Abstract: The concept of a molecular pair as the base of organization for matter successfully describes the polymerization phenomena. For this reason, a diatomic hypothesis is hereto postulated. According to the diatomic hypothesis, matter is organized in ...

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.

Green communication is a new focus within the telecommunications industry, leading to various innovative ideas how to optimize communication in order to achieve energy savings. While the majority of those ideas target the transport layer of communication systems, this paper takes a different approach and proposes an innovation for the application layer by introducing a novel concept in the mobi...

In this paper, the Hyper - Zagreb index of the Cartesian product, composition and corona product of graphs are computed. These corrects some errors in G. H. Shirdel et al.[11].

in this paper, we determine the degree distance of the complement of arbitrary mycielskian graphs. it is well known that almost all graphs have diameter two. we determine this graphical invariant for the mycielskian of graphs with diameter two.
