We consider five dimensional (5D) supersymmetric SO(10) compactified on the orbifold S/(Z2 × Z ′ 2) such that the SO(10) gauge symmetry is broken on both fixed points (branes), and the residual gauge symmetry is SU(3)c × SU(2)L×U(1)Y ×U(1)X . We explore one example in which the gauge symmetries on the two branes are respectively SU(5)×U(1) and SU(4)c × SU(2)L × SU(2)R, and the MSSM gauge symmet...

BACKGROUND AND PURPOSE The properties and performance of a new low-monomer cement were examined in this prospective randomized, controlled RSA study. 5-year data have already been published, showing no statistically significant differences compared to controls. In the present paper we present the 10-year results. METHODS 44 patients were originally randomized to receive total hip replacement ...

The Lorentzian Kac-Moody algebra E11, obtained by doubly overextending the compact E8, is decomposed into representations of its canonical hyperbolic E10 subalgebra. Whereas the appearing representations at levels 0 and 1 are known on general grounds, higher level representations can currently only be obtained by recursive methods. We present the results of such an analysis up to height 120 in ...
