We present a new numerical algorithm for evolving the Mixmaster spacetimes. By using symplectic integration techniques to take advantage of the exact Taub solution for the scattering between asymptotic Kasner regimes, we evolve these spacetimes with higher accuracy using much larger time steps than previously possible. The longer Mixmaster evolution thus allowed enables detailed comparison with...

The diffractive production of vector mesons in ep interactions at low x is a subject of heated debates. This chapter consists of four contributions written by the original authors and expresses the possible scenarios which are to be investigated experimentally. 1 Hard diffractive vector meson production contributed by L. Frankfurt, W. Koepf and M. Strikman The derivation of our QCD formulas [1]...

We review some selected topics in the decays of heavy flavours, beauty and charm, which are of principal interest at HERA-B and HERA. The topics in B physics include: an update on the quark mixing matrix and CP violating phases, issues bearing on an improved resolution on the CP-violating phase ∆(sin 2β), prospects of measuring radiative and semileptonic rare B decays, the B 0 s-B 0 s mixing ra...

We establish a direct correspondence between two congruence properties for finite algebras. The first property is that minimal sets of type i omit tails. The second property is that congruence lattices omit pentagons of type i.

A retrospective study was conducted between July 1, 2004 and June 30, 2009 at Chiang Mai University Hospital among 138 patients with candidemia; 85 patients (61.6%) were male and the mean age was 57.7 +/- 19.4 years. Seventy-eight patients (56.5%) had underlying medical conditions. Candida albicans and non-albicans Candida were identified in 42 (30.4%) and 96 (69.6%) patients, respectively. Not...

BACKGROUND The Bernese periacetabular osteotomy (PAO) is a recognized joint-preserving procedure. Achieving joint stability without creating impingement is important, but the orientation target that best balances these sometimes competing goals has not yet been clearly defined. Moreover, the learning curve of this challenging procedure has not been described. QUESTIONS/PURPOSES The purposes o...
