In vivo "footprints" of the glnA regulatory region under activating conditions demonstrate that the three most upstream activator sequences bind the protein NRI in the cell. Together, protections at these sites span six of seven consecutive major grooves and lie on the same helix face. E sigma 54 protects two major grooves of DNA approximately 60 base pairs downstream at the glnAp2 promoter and...

Abstract. The aim of this note is to provide an introduction to the algebraic, geometric and quantum field theoretic ideas that lie behind the KontsevichCattaneo-Felder formula for the quantization of Poisson structures, and to show how the quantization formula itself naturally arises when one couples the form a Feynman integral should have in order to reproduce the given Poisson structure as t...

let $g$ be a simple graph with an orientation $sigma$‎, ‎which ‎assigns to each edge a direction so that $g^sigma$ becomes a‎ ‎directed graph‎. ‎$g$ is said to be the underlying graph of the‎ ‎directed graph $g^sigma$‎. ‎in this paper‎, ‎we define a weighted skew‎ ‎adjacency matrix with rand'c weight‎, ‎the skew randi'c matrix ${bf‎ ‎r_s}(g^sigma)$‎, ‎of $g^sigma$ as the real skew symmetric mat...

Abstract. The aim of the note is to provide an introduction to the algebraic, geometric and quantum field theoretic ideas that lie behind the KontsevichCattaneo-Felder formula for the quantization of Poisson structures. We show how the quantization formula itself naturally arises when one imposes the following two requirements to a Feynman integral: on the one side it has to reproduce the given...

The purpose of present study was to formulate microemulsion composed of oleic acid+phosphate buffer (PB)+Tween 80+ethanol and to investigate its potential as drug delivery system for an antitubercular drug rifampicin. The pseudo-ternary phase diagram has been delineated at constant surfactant/cosurfactant ratio (K(m) 0.55). Conductivity (sigma) and viscosity (keta) studies with variation in Phi...

A revision of the torodial Kaluza-Klein compactification of the massless sector of the E8 × E8 heterotic string is given. Under the solvable Lie algebra gauge the dynamics of the O(p, q)/(O(p)×O(q)) symmetric space sigma model which is coupled to a dilaton, N abelian gauge fields and the Chern-Simons type field strength is studied in a general formalism. The results are used to derive the boson...

We present calculations at the relativistic coupled cluster theory that predict the (1)Sigma(0) (+) ground state of CUO to lie 58.2 kJ/mol below the first excited state, (3)Phi(2). This can be contrasted with the outcome of earlier density functional theory and complete active space second order perturbation theory (CASPT2) calculations that both predicted a (3)Phi(2) ground state upon inclusio...

Within the framework of flux formulation Double Field Theory (DFT) we employ a generalised Scherk-Schwarz ansatz and discuss classification twists that in presence strong constraint give rise to constant fluxes interpreted as gaugings. We analyse various possibilities turning on $H_{ijk}, F_{ij}{}^k, Q_i{}^{jk}$ $R^{ijk}$, solutions for allowed each case. While do not impose DFT (or equivalentl...

a unital $c^*$ -- algebra $mathcal a,$ endowed withthe lie product $[x,y]=xy- yx$ on $mathcal a,$ is called a lie$c^*$ -- algebra. let $mathcal a$ be a lie $c^*$ -- algebra and$g,h:mathcal a to mathcal a$ be $bbb c$ -- linear mappings. a$bbb c$ -- linear mapping $f:mathcal a to mathcal a$ is calleda lie $(g,h)$ -- double derivation if$f([a,b])=[f(a),b]+[a,f(b)]+[g(a),h(b)]+[h(a),g(b)]$ for all ...
