Nakon otkrivanja i identifikovanja pandemijskog virusa gripa A (H1N1) 2009, razvijeno je i licencirano više od 30 vakcina, a od septembra 2009. godine imunizacija protiv gripa postala je sastavni deo programa sprečavanja i suzbijanja ovog oboljenja u mnogim zemljama sveta [1]. Istovremeno sa sprovođenjem vakcinacije, uveden je nadzor nad uzgrednim pojavama s ciljem da se registruju svi neželjen...

We consider Euclidean SU(N) Yang-Mills theory on the space G×R, where G is a compact semisimple Lie group, and introduce first-order BPS-type equations which imply the full YangMills equations. For gauge fields invariant under the adjoint G-action these BPS equations reduce to first-order matrix equations, to which we give instanton solutions. In the case of G = SU(2) ∼= S, our matrix equations...

The term “sutureless aortic valve” (su-AV) describes a type of valve which facilitates anchoring of bioprostheses in the aortic position without use of conventional sutures. Although all valve prostheses used for transcatheter aortic valve implantation or replacement (TAVI or TAVR) follow the same principle, they are implanted by wire-based techniques as opposed to su-AVs, which are implanted b...

We embed the minimal left-right model SU(2)L × SU(2)R × U(1)B−L into an SU(4)W gauge group, and break the unified group via five-dimensional S /(Z2 × Z2) orbifolding. Leptons are fitted into SU(4)W multiplets and located on a symmetry preserving O brane, while quarks are placed onto an O brane where the symmetry is broken. This approach predicts sin θW = 0.25 for the weak mixing angle at tree l...

The renormalization group equations (RGEs) of the mass matrices of quarks and leptons in a SO(10) model with two Higgs scalars in the Yukawa coupling are studied. This model is the minimal model of SUSY and non-SUSY SO(10) GUT which can reproduce all the experimental data. Non-SUSY SO(10) GUT model has the intermediate energy phase, Pati-Salam phase, and passes through the symmetry breaking pat...

Human multimodal communicative behaviors form a tightly integrated whole. By matching up gestural features with a carefully time-tagged transcription of the speech, we can observe how gesture features and discourse unit transitions cohere. Space usage SU is a key gestural component. We summarize the theory of SU. In our experiments where subjects make action plans around a terrain map, such SU ...

Theoretical predictions are given for the light-flavor sea-quark distributions including the strange quark ones on the basis of the flavor SU(3) version of the chiral quark soliton model. Careful account is taken here of the SU(3) symmetry breaking effects due to the mass difference between the strange and nonstrange quarks. This effective mass difference ∆ms between the strange and nonstrange ...

It is generally assumed that deviations from flavor SU(3) symmetry arise entirely from quark mass-differences, reflected in the mass splittings between strange and nonstrange members of the same SU(3) multiplet. Under this assumption, a parametrization is proposed which expresses the ratios of GamowTeller to Fermi matrix elements for nucleon and hyperon beta decays entirely in terms of two SU(3...

We present what we believe is the minimal three-family AdS/CFT model compactified on a nonabelian orbifold S5/(Q × Z3). Nontrivial irreps of the discrete nonabelian group Q × Z3 are identified with the 4 of SU(4) R symmetry to break all supersymmetries, and the scalar content of the model is sufficient to break the gauge symmetry to the standard model. According to the conformality hypothesis t...
