The Busemann function plays a very important role in studying topology and geometry of a complete Riemannian manifold. In this paper, the Busemann functions on
The density, drift velocity and reproducibility of the plasma produced by a cableplasma gun array have been measured with a charge collector array. The plasma i
(FePt/Ag)n nano-multilayers were deposited on MgO(100) single crystal with laser ablation and then subjected to annealing. FePt L10 grains with (001) texture an
We consider the exact controllability problem from boundary for thin shells. Under some check-able geometric assumptions on the middle surface, we establish the
