We study the role of rotational symmetry in the systems where nonabelian Berry potentials emerge as a result of integrating out fast degrees of freedom. The conserved angular momentum is constructed in the presence of a non-abelian Berry potential, which is formulated using Grassmann variables. The modifications on conventional angular momentum are discussed in close analogy with monopole syste...

Type IIS restriction endonuclease BtsCI (GGATG 2/0) is a neoschizomer of FokI (GGATG 9/13) and cleaves closer to the recognition sequence. Although M.BtsCI shows 62% amino acid sequence identity to M.FokI, BtsCI and FokI restriction endonucleases do not share significant amino acid sequence similarity. BtsCI belongs to a group of Type IIS restriction endonucleases, BsmI, Mva1269I and BsrI, that...

M(atrix) theory compactified on an orbifold T9/Z2 is studied. Via zero-brane parton scattering we find that each of the 2 = 254 orbifold fixed points carry −1/32 units of zero-brane charge. The anomalous flux is cancelled by introducing a twisted sector consisting of 32 zero-branes that are spacetime supersymmetry singlets. These twisted sector zero-branes are nothing but gravitational waves pr...

Q-ball configuration that represents oscillating or spinning closed membrane is constructed via M(atrix) theory. Upon gravitational collapse Q-balls are expected to form Schwarzschild black holes. For quasi-static spherical membrane, we probe spacetime geometry induced by monopole moment via D0-parton scattering off the Q-ball. We find a complete agreement with long distance potential calculate...

In this article, we show – using a reasoning applicable to both the excitation spectrum in the chiral bag model and the hyperfine structure of diatomic molecules – that the generic form of a nonabelian Berry potential appears in heavy quark effective theory (HQET) and that the Berry potential vanishes for the solitonheavy meson bound state in the heavy-quark limit. The vanishing of the Berry po...

Aspects of d = 4,N = 4 superconformal U(N) gauge theory are studied at finite temperature. Utilizing dual description of large N and strong coupling limit via Type IIB string theory compactification on Schwarzschild anti-de Sitter spacetime, we study correlations of WilsonPolyakov loops and heavy quark potential thereof. We find that the heavy quark potential is Coulomb-like and has a finite ra...

Utilizing coset superspace approach, dual actions of super D1-and D3-branes on AdS × S are constructed by carrying out duality transformation of world-volume U(1) gauge field. Resulting world-volume actions are shown to possess expected SL(2,Z) properties. Crucial ingredient for deriving SL(2,Z) transformation property of the D-brane actions is covariance of SU(2, 2|4) coset superspace algebra ...

It was shown by Gaborit el al. [10] that a Euclidean self-dual code over GF (4) with the property that there is a codeword whose Lee weight ≡ 2 (mod 4) is of interest because of its connection to a binary singly-even self-dual code. Such a self-dual code over GF (4) is called Type I. The purpose of this paper is to classify all Type I codes of lengths up to 10 and extremal Type I codes of lengt...

For any non-negative integer v we construct explicitly ⌊v2⌋+1 independent covariant bilinear differential operators from Jk,m × Jk′,m′ to Jk+k′+v,m+m′ . As an application we construct a covariant bilinear differential operator mapping S (2) k ×S (2) k′ to S (2) k+k′+v. Here Jk,m denotes the space of Jacobi forms of weight k and index m and S (2) k the space of Siegel modular forms of degree 2 a...

Purpose : to study the formed images of sexual self-consciousness in persons who applied for permission change their sex. Materials and methods 80 people were examined, 40 whom sex (20 male 20 female biological sex). The comparison group — men women, whose gender identity coincides with Methods Sandra Bem's BSRI (Bem Sex-Role Inventory) test, V.V. Stolin's self-attitude questionnaire, O.L. Kust...
