Patterns in molecular topology and complexity for long-chain branching are quantitatively described. The Wiener number, the topological complexity index, and a new index of 3-starness are used to quantify polymer structure. General formulas for these indices were derived for the cases of 3-arm star, H-shaped, and B-arm comb polymers. The factors affecting complexity in monodisperse polymer syst...

An experimental method to determine the (n,γ) cross section of short-living s-process branching points using data of the inverse (γ ,n) reaction is presented. The method was used to observe the branching point nucleus 95Zr because the elemental abundance patterns corresponding to this branching point cannot be reproduced by full stellar models and a possible error source is the neutron capture ...

In this paper, we study the branching ratios of B → K 0 (1430)l+l− decay, where K 0 (1430) being the p–wave scalar meson, in the supersymmetric models. The branching ratios are estimated when short and long distance effects are taken into account. It is found that the B → K 0 (1430)l+l− (l = μ, τ) decay is measurable at LHC. Measurement of these branching ratios for the semileptonic rare B → K ...

The one-step model for chemistry has a successful history in providing a paradigm for describing many kinds of flame structure. If the activation energy is considered to be a large parameter, then an asymptotic picture emerges that is often simple enough to provide explicit solutions which describe such phenomena as structure, stability, ignition, and extinction. Qualitatively correct descripti...

On the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in Langmuir- Hinshelwood approach at room temperature has been offered.The effect of oxygen on the kinetics of process in the presence, [O2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. Over time the chain degenerate branching...

We extend in two directions our previous results about the sampling and the empirical measures of immortal branching Markov processes. Direct applications to molecular biology are rigorous estimates of the mutation rates of polymerase chain reactions from uniform samples of the population after the reaction. First, we consider nonhomogeneous processes, which are more adapted to real reactions. ...
