Computing Ramifications by Postprocessing

Intrahepatic ramifications of the portal vein in the horse

The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...

Distilling Gaussian states with Gaussian operations is impossible.

We show that no distillation protocol for Gaussian quantum states exists that relies on (i) arbitrary local unitary operations that preserve the Gaussian character of the state and (ii) homodyne detection together with classical communication and postprocessing by means of local Gaussian unitary operations on two symmetric identically prepared copies. This is in contrast to the finite-dimension...

Superconvergence and Postprocessing of Fluxes from Lowest-Order Mixed Methods on Triangles and Tetrahedra

Some Aspects of Parallel Postprocessing for Numerical Simulation

The topics discussed in this paper are closely connected to the development of parallel finite element algorithms and software based on domain decomposition [1, 2]. Numerical simulation on parallel computers generally produces data in large quantities being kept in the distributed memory. Traditional methods of postprocessing by storing all data and processing the files with other special softw...

Postprocessing for the Discontinuous Galerkin Method over Nonuniform Meshes

A postprocessing technique based on negative order norm estimates for the discontinuous Galerkin methods was previously introduced by Cockburn, Luskin, Shu, and Süli [Proceedings of the International Symposium on Discontinuous Galerkin Methods, Springer, New York, pp. 291– 300; Math. Comput., 72 (2003), pp. 577–606]. The postprocessor allows improvement in accuracy of the discontinuous Galerkin...
