Third Dimension

We have investigated three-dimensional (3D) effects in sub-micron GaAs MESFETs using a parallel Monte Carlo device simulator, PMC-3D [1]. The parallel algorithm couples a standard Monte Carlo particle simulator for the Boltzmann equation with a 3D Poisson solver using spatial decomposition of the device domain onto separate processors. The scaling properties of the small signal parameters have been simulated for both the gate width in the third dimension as well as the gate length. For realistic 3D device structures, we find that the main performance bottleneck is the Poisson solver rather than the Monte Carlo particle simulator for the parallel successive overrelaxation (SOR) scheme employed in [1]. A parallel multigrid algorithm is reported and compared to the previous SOR implementation, where considerable speedup is obtained.

Human Livers

The scaling properties of the portal vein and the hepatic vein are examined, based on three-dimensional computed tomography images of casts of human livers. In particular, a quantitative analysis of the branching ratio based on the Strahler ordering scheme as well as the diameter and length ratios are performed. To quantify the segment anatomy of the liver, the volume of supplied liver parenchyma is measured and related to the corresponding vessel radius. The implications of these findings for segment-oriented liver surgery are discussed. We also investigate the 3D interdependence of the intertwined portal and hepatic veins based on a concept of tree distance that will be introduced.
