Metastatic disease accounts for more than 90% of cancer-related deaths, but the development of effective antimetastatic agents has been hampered by the paucity of clinically relevant preclinical models of human metastatic disease. Here, we report the development of a mouse model of spontaneous breast cancer metastasis, which recapitulates key events in its formation and clinical course. Specifi...

We present the first calculation of the electromagnetic form factor of the π meson at physical light quark masses. We use configurations generated by the MILC Collaboration including the effect of u, d, s and c sea quarks with the highly improved staggered quark formalism. We work at three values of the lattice spacing on large volumes and with u=d quark masses going down to the physical value....

The s-wave pion-kaon (πK) scattering lengths at zero momentum are calculated in lattice QCD with sufficiently light u/d quarks and strange quark at its physical value by the finite size formula. The light quark masses correspond to mπ = 0.330−0.466 GeV. In the “Asqtad” improved staggered fermion formulation, we measure the πK four-point correlators for both isospin I = 1/2 and 3/2 channels, and...

Network contention has an increasingly adverse effect on the performance of parallel applications with increasing size of parallel machines. Machines of the petascale era are forcing application developers to map tasks intelligently to job partitions to achieve the best performance possible. This paper presents a framework for automated mapping of parallel applications with structured communica...

Several caveats should be pointed out to the reader. First, I think that the past 20 years of my life are evidence of my inability to estimate the time and effort necessary to calculate the spectrum of QCD. Used to doing analytic calculations that took a few months at most, I did not imagine as I started my first Monte Carlo calculation that 20 years later I would still be doing similar calcula...

Effects of the quark field on the ghost propagator of the lattice Landau gauge are investigated by using the unquenched SU(3) configurations produced by the MILC collaboration and compared with quenched gauge configurations of SU(2) first copy of the overrelaxation gauge fixing, the parallel tempering (PT) gauge fixing and quenched SU(3) 564 configurations. We measure the color symmetric and th...

I will review heavy baryon chiral perturbation theory for the nucleon delta degrees of freedom and then examine the recent dynamical lattice calculations of the nucleon mass from the BMW, ETM, JLQCD, LHP, MILC, NPLQCD, PACS-CS, QCDSF/UKQCD and RBC/UKQCD Collaborations. Performing the chiral extrapolations of these results, one finds remarkable agreement with the physical nucleon mass, from each...
