Nucl.Phys.Proc.Suppl. 53 (1997) 222-224 The investigation of light sea-quark effects in lattice QCD with dynamical
Wilson fermions requires both larger physical volumes and finer lattice
resolutions ...than achieved previously. As high-end supercomputers like the
512-node APE Tower provide the compute power to perform a major step towards
the chiral limit (T-chi-L), we have launched a feasibility study on a 24^3 x 40
lattice. We approach the chiral limit--while refining the resolution--, using
the standard Wilson fermion action. Following previous work, our Hybrid Monte
Carlo simulation runs at beta=5.6 and two kappa-values, 0.1575 and 0.158. From
our study, we are confident that, for the APE Tower, a realistic working point
has been found corresponding to a volume of 2 fm^3, with chirality
characterized by 1/(a m_pi) = 5.6.
Major chemotherapeutic alternatives for AML have been implemented and compared in three multicenter studies, including a total of 877 adult patients of all ages. The results strongly suggest that ...myelosuppressive postinduction treatment is a prerequisite for the achievement of long-term remissions. In addition, it was possible to establish an important antileukemic effect of monthly maintenance chemotherapy. Initial results from an intensive two-course preremission therapy concept revealed good practicability and acceptable toxicity, as well as promising response and remission durations by this new approach.
We present results on the static potential, and torelon and glueball masses from simulations of QCD with two flavours of dynamical Wilson fermions on \(16^3\times 32\) and \(24^3\times 40\) lattices ...at \(\beta=5.6\).
Results from two studies of full QCD with two flavours of dynamical Wilson fermions are presented. At beta=5.6, the region 0.83 > m_pi/m_rho > 0.56 at m_pia > 0.23 L^{-1} is explored. The SESAM ...collaboration has generated ensembles of about 200 statistically independent configurations on a 16^3 x 32-lattice at three different kappa-values and is entering the final phase of data analysis. The TXL simulation on a 24^3 x 40-lattice at two kappa-values has reached half statistics and data analysis has started recently, hence most results presented here are preliminary. The focus of this report is fourfold: we demonstrate that algorithmic improvements like fast Krylov solvers and parallel preconditioning recently introduced can be put into practise in full QCD simulations, we present encouraging observations as to the critical dynamics of the Hybrid Monte Carlo algorithm in the approach to the chiral limit, we mention signal improvements of noisy estimator techniques for disconnected diagrams to the pi-N sigma term, and we report on SESAM's results for light hadron spectrum, light quark masses, and heavy quarkonia.
