A 50 yo female with PSC and a bleeding duodenal varix (DV) was evaluated for possible enbucrilate therapy. Endoscopically (Figure 1), the DV was high risk for rebleeding but the relative in-flow and out-flow were uncertain. CT (Figure 2) showed portal vein thrombosis (PVT) and the vascular anatomy of the DV to consist of inflow from the superior mesenteric vein (SMV) with outflow through the DV...

In 1983, Antontsev, Kazhikhov, and Monakhov published a proof of the existence uniqueness solutions to 3D Euler equations in which on certain inflow boundary components fluid is forced into domain while other outflow drawn out domain. A key tool they used was linearized vorticity form. We extend their result problem multiply connected domains establish compatibility conditions initial data that...

In this paper we investigate the superconvergence properties of the discontinuous Galerkin method applied to scalar first-order hyperbolic partial differential equations on triangular meshes. We show that the discontinuous finite element solution is O(hp+2) superconvergent at the Legendre points on the outflow edge for triangles having one outflow edge. For triangles having two outflow edges th...

BACKGROUND Contrast-enhanced ultrasound (CEUS) has recently been proposed as a minimally- invasive, alternative method for blood volume measurement. This study aims at comparing the accuracy of CEUS and the classical thermodilution techniques for volume assessment in an in-vitro set-up. METHODS The in-vitro set-up consisted of a variable network between an inflow and outflow tube and a roller...

PURPOSE To investigate the hemodynamic characteristics of lateral carotid artery aneurysms in a canine model and to determine their influence on coils and balloons. MATERIALS AND METHODS Forty aneurysms were created in fourteen dogs and their hemodynamic characteristics and influence on coils and balloons were evaluated with angiography and color Doppler pre- and postplacement. Twenty aneurys...

This paper describes a model of dynamic decision making in the Dynamic Stocks and Flows (DSF) task, developed using the ACT-R cognitive architecture. This task is a simple simulation of a water tank in which the water level must be kept constant whilst the inflow and outflow changes at varying rates. The basic functions of the model are based around three steps. Firstly, the model predicts the ...
