摘要：We present results for the strangeness contribution to the nucleon, hN|¯ ss|Ni and to the spin of the nucleon, Ds. By combining several variance reduction techniques for all-to-all propagators we are able to obtain gains in terms of computer time of factors of 25–30 for the disconnected loop that is needed within the calculation of Ds, relative to the standard approach of just employing time partitioning/dilution . For hN|¯ ss|Ni, the error is dominated by the gauge noise.
