Histone H3-lysine(9) (H3K9) trimethyltransferase gene Su(var) 3-9 was cloned and identified in three Spodoptera insects, Spodopterafrugiperda (S. frugiperda), S. exigua and S. litura. Sequence analysis showed that Spodoptera Su(var) 3-9 is highly conserved evolutionarily. Su(var) 3-9 protein was found to be localized in the nucleus in Sf9 cells, and interact with histone H3, and the heterochrom...

We calculate the tree-level oblique corrections to electroweak precision observables generated in higgless models of electroweak symmetry breaking with a 5D SU(2)L×SU(2)R ×U(1)B−L gauge group on a warped background. In the absence of brane induced kinetic terms (and equal left and right gauge couplings) we find the S parameter to be ∼ 1.15, while T ∼ U ∼ 0, as in technicolor theories. Planck br...

We study the breaking of a supersymmetric SO(10) GUT in 6 dimensions by orbifold compactification. In 4 dimensions we obtain a N=1 supersymmetric theory with the standard model gauge group enlarged by an additional U(1) symmetry. The 4-dimensional gauge symmetry is obtained as intersection of the Pati-Salam and the Georgi-Glashow subgroups of SO(10), which appear as unbroken subgroups in the tw...

We study the SU(2) gluon and ghost propagators in Landau gauge on lattices up to a size of 112 4. A comparison with the SU(3) case is made and finite-volume effects are then investigated. We find that for a large range of momenta the SU(2) and SU(3) propagators are remarkably alike. In the low-momentum region we compare with recent results obtained in DSE studies on a 4-torus. c Copyright owned...

We present two 3-family SU(5) grand unified models in the heterotic string theory. One model has 3 chiral families and 9 pairs of 5+ 5 Higgs fields, and an asymptotically-free SU(2) ⊗ SU(2) hidden sector, where the two SU(2)s have different matter contents. The other model has 6 left-handed and 3 righthanded 10s, 12 left-handed and 9 right-handed 5s, and an asymptotically-free SU(3) hidden sect...

It is shown that the manifold S can be equipped with a natural Nambu structure arising out of a cross product on the tangent space. Further, the group action of SU(2) on S is shown to be Nambu action. Moreover, we compare the action of SU(2) on spinors with that of a Nambu system.

Dighe, Gronau and Rosner have shown that, by assuming SU(3) flavor symmetry and first-order SU(3) breaking, it is possible to extract the CP angles α and γ from measurements of the decay rates of B 0 d (t) → π + π − , B 0 d → π − K + and B + → π + K 0 , along with their charge-conjugate processes. We extend their analysis to include the SU(3)-related decays B 0 s → π + K − , B 0 s (t) → K + K −...
