We present hierarchical streamline bundles, a new approach to simplifying and visualizing 2D flow fields. Our method first densely seeds a flow field and produces a large number of streamlines that capture important flow features such as critical points. Then, we group spatially neighboring and geometrically similar streamlines to construct a hierarchy from which we extract streamline bundles a...

Various cellulose and dextran anion exchangers bind bile salts in vitro under conditions of pH and ionic strength resembling those in the lumen of the small intestine. Of these substances, diethylaminoethyl (DEAE) cellulose, guanidoethyl cellulose, and DEAE Sephadex reduced hypercholesterolemia when added to the diet of cholesterol-fed cockerels. In addition, DEAE Sephadex reduced serum sterols...

Streamline is a stream-based communication subsystem that spans from embedded hardware to userspace processes. It improves performance of memory and I/O bound applications by constructing tailor-made datapaths for each application at runtime. Datapath optimisation removes unnecessary copying, context switching and cache replacement. It simplifies integration of embedded and distributed hardware...

The activity of the antiviral protein induced by various ratios of poly rI-rC and diethylaminoethyl (DEAE)-dextran was studied. It was found that, when large doses of poly rI-rC were used, very little viral interference was observed. This effect was initially attributed to the cells being refractory for production of antiviral protein. Subsequent experiments offered alternative explanations sug...

N-Acetyl-fi-D-glucosaminidase activities were determined in homogenates of marmoset kidney, in serum and in urine by using the 4-methylumbelliferyl substrate. The enzyme activity was separated into several components by DEAE-cellulose ion-exchange chromatography, starch-gel electrophoresis and isoelectric focusing. The kidney contained two major forms of the enzyme, A and B, which had similar p...

A fraction obtained from detergent-extract of sea urchin or starfish spermatozoa using DEAE-cellulose chromatography reactivated Triton X-100 models of the spermatozoa in a cAMP-dependent manner. The DEAE fraction contained cAMP-dependent protein kinase with a high level of specific activity. Rabbit muscle inhibitor protein highly specific for cAMP-dependent protein kinases inhibited the abilit...
