UNLABELLED nanoScan is a high-resolution integrated system for consecutive PET and MR imaging of small laboratory animals. We evaluated the performance of the system, using the NEMA NU 4-2008 protocol for the PET component and the NEMA MS 1-2007, MS 2-2008, and MS 3-2007 standards for the MR imaging component. METHODS The imaging system uses magnetically(More)
We perform dynamical QCD simulations with nf = 2 overlap fermions by hybrid Monte-Carlo method on 64 to 83 × 16 lattices. We study the problem of topological sector changing. A new method is proposed which works without topological sector changes. We use this new method to determine the topological susceptibility at various quark masses.
The speed, bandwidth and cost characteristics of today’s PC graphics cards make them an attractive target as general purpose computational platforms. High performance can be achieved also for lattice simulations but the actual implementation can be cumbersome. This paper outlines the architecture and programming model of modern graphics cards for the(More)

We calculate the pressure (p), the energy density (ǫ) and the baryon density (nB) of QCD at finite temperatures (T) and chemical potentials (μ). The recently proposed overlap improving multi-parameter reweighting technique is used to determine observables at nonvanishing chemical potentials. Our results are obtained by studying nf=2+1 dynamical staggered(More)
