The Drosophila Su(Hw) protein is a multi-zinc finger DNA binding factor required for the gypsy insulator function. At the gypsy element, Su(Hw) recruits partners Centrosomal Protein of 190 kD (CP190) and Modifier of mdg4 67.2 kD isoform (Mod67.2), which are required for the enhancer blocking and barrier functions of the insulator. Our genome-wide studies have identified thousands of endogenous ...

We present a 6D orbifold model on T 2/Z2 which emerges as intermediate step in the compactification of the heterotic string to the supersymmetric standard model in four dimensions. It has SU(6) gauge symmetry in the bulk and two pairs of inequivalent fixed points with unbroken SU(5) and SU(2)× SU(4) symmetry, respectively. All anomalies are cancelled by the GreenSchwarz mechanism. Two quark-lep...

We study quenched SU(N) gauge theories with fermions in the two-index symmetric, antisymmetric and the adjoint representations. Our main motivation is to check whether at large number of colours those theories become non-perturbatively equivalent. We prove the equivalence assuming that the charge-conjugation symmetry is not broken in pure Yang-Mills theory. We then carry out a quenched lattice ...

We use the algebraic curve and Lüscher’s μ-term to calculate the leading order finite size corrections to the dispersion relation of giant magnons in the SU(2)× SU(2) sector of AdS4 ×CP3. We consider a single magnon as well as one magnon in each SU(2). In addition the algebraic curve computation is generalized to give the leading order correction for an arbitrary multi-magnon state in the SU(2)...

We study the spectrum of the confining strings in four-dimensional SU(N) gauge theories. We compute, for the SU(4) and SU(6) gauge theories formulated on a lattice, the string tensions σk related to sources with ZN charge k, using Monte Carlo simulations. Our results are consistent with the sine formula σk/σ = sin k π N / sin π N for the ratio between σk and the standard string tension σ. For t...

The classical Yang-Mills equations are solved for arbitrary semi-simple gauge groups in the Schwinger-Fock gauge. A new class of SU(N) instantons is presented which are not embeddings of SU(N-1) instantons but have non-trivial SU(N) color structure and carry winding number n = N (N 2 − 1)/6. Explicit configurations are given for SU(3) and SU(4) gauge groups. By means of the Atiyah Manton proced...

Photorespiratory activity was measured in entire plants of five tobacco variants. These tobacco variants are: the green type N. tabacum var. John W illiam’s Broadleaf (su/su Aur/aur or su/su Aur/Aur) the chlorophyll-deficient tobacco mutant Su/su (Su/su Aur/Aur) and the chlorophylldeficient mutant Su/su var. Aurea (Su/su Aur/aur). Furthermore, two recently characterized phenotypes originating f...

Recently, Sadakane [12] proposes a new fast and memory e cient algorithm for sorting su xes of a text in lexicographic order. It is important to sort su xes because an array of indexes of su xes is called sufx array and it is a memory e cient alternative of the su x tree. Sorting su xes is also used for the Burrows-Wheeler transformation in the Block Sorting text compression, therefore fast sor...
