Valence topological charge-transfer (CT) indices are applied to the calculation of dipole moments mu. The mu calculated by algebraic and vector semisums of the CT indices are defined. The model is generalized for molecules with heteroatoms and corrected for sp(3)-heteromolecules. The ability of the indices for the description of the molecular charge distribution is established by comparing them...

We consider interacting Bose gas in thermal equilibrium assuming a positive and bounded pair potential V(r) such that 0< integral dr V(r)=a< infinity. Expressing the partition function by the Feynman-Kac functional integral yields a classicallike polymer representation of the quantum gas. With the Mayer graph summation techniques, we demonstrate the existence of a self-consistent relation rho(m...

Isotype switching is the DNA recombination mechanism by which antibody genes diversify immunoglobulin effector functions. In contrast to V(D)J recombination, which is mediated by RAG1, RAG2 and DNA double-stranded break (DSB) repair proteins, little is known about the mechanism of switching. We have investigated the role of DNA DSB repair in switch recombination in mice that are unable to repai...

The edge Szeged index of a connected graph G is defined as the sum of products mu(e|G)mv(e|G) over all edges e = uv of G, where mu(e|G) is the number of edges whose distance to vertex u is smaller than the distance to vertex v, and mv(e|G) is the number of edges whose distance to vertex v is smaller than the distance to vertex u. In this paper, we determine the n-vertex unicyclic graphs with th...

A paradoxical symmetry breaking--development of a unidirectional flow via thermal instability--is predicted by an analytical solution for compressible convection near a point source of both heat and gravity. Such a flow can propel a cosmic hot body (e.g., a protostar) in a molecular cloud. This convection emerges at the critical Rayleigh number Ra = l(l+1) [2l(l+1)+1+3 mu(V)/2]gamma/(gamma-1), ...

If H denotes the classical Hilbert transform and Hu(x) = v(x), then the functions u(x) and v(x) are the values on the real axis of a pair of conjugate functions, harmonic in the upper half-plane. This note gives a generalization of the above concepts in which the Laplace equation Deltau = 0 is replaced by the Yukawa equation Deltau = mu(2)u and in which the Cauchy-Riemann equations have a corre...

1. The electrophoretic mobility values for mitochondria prepared from rat kidney and liver measured in 0.125m-potassium chloride-0.02m-tris, pH7.4, are: -0.78(s.e.m.+/-0.02)mu/sec./v/cm. (29 experiments) and -1.06(s.e.m.+/-0.01) mu/sec./v/cm. (21 experiments) respectively. 2. These mobility values are unaffected by washing and spontaneous swelling at 25 degrees , indicating a stable electrokine...

Let $\\mu$ be a Radon measure on $\\mathbb{R}^d$. We define and study conical energies $\\mathcal{E}\_{\\mu,p}(x,V,\\alpha)$, which quantify the portion of lying in cone with vertex $x\\in\\mathbb{R}^d$, direction $V\\in G(d,d-n)$, aperture $\\alpha\\in (0,1)$. use these to characterize rectifiability big pieces Lipschitz graphs property. Furthermore, if we assume that has polynomial growth, gi...

True Random Number Generator (TRNG) is used in many applications, generally for generating random cryptography keys. In this way, the trust of system depends on quality numbers generated. However, entropy fluctuations produced by external perturbations generate some false positives sequence. These can a disastrous scenario, depending application. This work presents results different tests to de...
