Concurrent multi-domain simulations in linear structural dynamics using multiple grid multiple time-scale (MGMT) method
Tejas Ruparel, Azim Eskandarian, James Lee
Work presented in this paper describes a general algorithm and its finite element implementation for performing concurrent multiple sub-domain simulations in linear structural dyna…
Finding the Force -- Consistent Particle Seeding for Satellite Aerodynamics
J. Brent Parham, L. A. Barba
When calculating satellite trajectories in low-earth orbit, engineers need to adequately estimate aerodynamic forces. But to this day, obtaining the drag acting on the complicated…
The dynamic X-ray nebula powered by the pulsar B1259-63
Oleg Kargaltsev, George G. Pavlov, Martin Durant +2
We present observations of the eccentric gamma-ray binary B1259-63/LS2883 with the Chandra X-ray Observatory. The images reveal a variable, extended about 4'', or about 1000 times…
Quasi-free photoproduction of eta-mesons off 3He nuclei
L. Witthauer, D. Werthmueller, I. Keshelashvili +70
Quasi-free photoproduction of -mesons has been measured off nucleons bound in He nuclei for incident photon energies from the threshold region up to 1.4 GeV. The experiment…
QCD at imaginary chemical potential with Wilson fermions
Andrei Alexandru, Anyi Li
We investigate the phase diagram in the temperature, imaginary chemical potential plane for QCD with three degenerate quark flavors using Wilson type fermions. While more expensive…
Charge asymmetry in high-energy photoproduction in the electric field of a heavy atom
E. J. Downie, R. N. Lee, A. I. Milstein +1
The charge asymmetry in the differential cross section of high-energy photoproduction in the electric field of a heavy atom is obtained. This asymmetry arises due to the C…
