We calculate the pressure in QCD with two and three light quarks on a lattice of size 16 3 × 4 using tree level improved gauge and fermion actions. We argue that for temperatures T > ∼ 2T c systematic effects due to the finite lattice cutoff and non-vanishing quark masses are below 15% in this calculation and give an estimate for the continuum extrapolated… (More)

We analyze the quark mass and flavour dependence of the QCD phase transition temperature. When the lightest pseudo-scalar meson mass (m PS) is larger than 2 GeV the critical temperature is controlled by the gluonic sector of QCD alone. For smaller values of the lightest meson mass the pseudo-critical temperature decreases slowly with m PS. For a large… (More)

We calculate the string tension, deconfinement transition temperature and bulk thermodynamic quantities of the SU(3) gauge theory using tree level and tadpole improved actions. Finite temperature calculations have been performed on lattices with temporal extent N τ = 3 and 4. Compared to calculations with the standard Wilson action on this size lattices we… (More)

In order to evaluate the efficacy, time-course of action and predictors of response to topical capsaicin, 39 patients with chronic post-herpetic neuralgia (PHN), median duration 24 months, were treated with 0.025% capsaicin cream for 8 weeks. During therapy the patients rated their pain on a visual analogue scale (VAS) and a verbal outcome scale. A… (More)

This paper discusses a methodology for quickly investigating problem areas in semiconductor wafer fabrication factories by creating a model for the production area of interest only (as opposed to a model of the complete factory operation). All other factory operations are treated as " black boxes ". Specific assumptions are made to capture the effect of… (More)

We analyze the latent heat and surface tension at the SU(3) deconfinement phase transition with tree level and tadpole improved Symanzik actions on lattices with temporal extent N τ = 3 and 4 and spatial extent N σ /N τ = 4, 6 and 8. In comparison to the standard Wilson action we do find a drastic reduction of cutoff effects already with tree level improved… (More)

We discuss the flavor dependence of the pressure and critical temperature calculated in QCD with 2, 2+1 and 3 flavors using improved gauge and staggered fermion actions on lattices with temporal extent Nτ = 4. For T > ∼ 2Tc we find that bulk thermodynamics of QCD with 2 light and a heavier strange quark is well described by 3-flavor QCD while the transition… (More)

This multicentre, randomized, double-blind, placebo-controlled, parallel group dose-ranging study compared the efficacy and tolerability of four doses of sumatriptan nasal spray (2.5, 5, 10 and 20 mg) with a placebo, in the acute treatment of a single migraine attack. In total, 544 patients received the study medication as a single spray in one nostril, to… (More)

Acknowledgements At the end of a long and intense experience like a PhD in physics, there is normally a long queue of people to thank. My first thanks go to my supervisor, Prof. Dr. Helmut Satz, for giving me this chance in a delicate moment of my life in which I had started to have doubts on myself. The challenging tasks he gave me and the many discussions… (More)

The finite-temperature chiral phase transition is investigated for three flavours of staggered quarks on a lattice of temporal extent Nτ = 4. In the simulation we use an improved fermion action which reduces rotational symmetry breaking of the quark propagator (p4-action), include fat-links to improve the flavour symmetry and use the tree level improved… (More)
