We present a discontinuous Galerkin pseudospectral time-domain (DG-PSTD) algorithm to solve elastic-/acoustic-wave propagation problems. The developed DG-PSTD algorithm combines the merits of ...

In this paper, a wideband quasi-isotropic antenna based on a U-shaped quarter-wavelength radiator structure is designed. By introducing a stepped structure into the conventional U-shaped ...

The ATLAS and ALICE collaborations have announced the first results of a new way to measure the “radial flow” of quark–gluon ...
