Realistic Rendering in "Details".

Rendering is far from solved. Even today, the rendered results still look artificial and overly perfect. To make rendering more realistic, we need details.

Low-Latency Rendering With Dataflow Architectures.

Recent years have seen a resurgence of virtual reality (VR), sparked by the repurposing of low-cost COTS components. VR aims to generate stimuli that appear to come from a source other than the interface through which they are delivered. The synthetic stimuli replace real-world stimuli, and transport the user to another, perhaps imaginary, "place.

Visibility, Topology, and Inertia: New Methods in Flow Visualization.

In this article, we address three different topics in scientific visualization. The first part introduces optimization strategies that determine the visibility of line and surface geometry, such that a balance between occlusion avoidance and preservation of context is found. The second part proposes new methods for the visualization of time-dependent fluid flows, including the accurate depiction of Lagrangian scalar fields, as well as a new category of vortex identification methods.

Topological Modeling for Vector Graphics.

Vector graphics refers to the use of geometrical primitives, such as Bézier curves, to represent digital images. It is becoming increasingly popular among graphic designers who need to deliver resolution-independent content that looks sharp across all types of desktop and mobile devices, or need to support user interactivity and animation. Unfortunately, most vector graphics tools today have many limitations, such as the inability to represent shapes sharing a common edge.

Successful in vivo recovery and extended storage of additive solution (AS)-5 red blood cells after deglycerolization and resuspension in AS-3 for 15 days with an automated closed system.

Background: Previously, cryopreserved red blood cell (RBC) units derived from CPD/AS-5 whole-blood (WB) collections have been limited to 24 hours postthaw storage (1-6 degrees C).

Study Design And Methods: Sixty-four leukoreduced (LR) and 54 nonleukoreduced (NLR) AS-5 (n = 118) RBC units from 500-mL WB collections were stored for 6 days, glycerolized, frozen (-70 +/- 5 degrees C) for at least 14 days, thawed, deglycerolized, and stored (1-6 degrees C) for 15 days resuspended in AS-3, using an automated closed-system cell processor (ACP 215, Haemonetics). Frozen units were stored in either ethylene vinyl acetate (EVA) or polyvinylchloride (PVC) bags.

Viability and function of 8-day-stored apheresis platelets.

Background: Methods of bacterial detection and pathogen inactivation of platelets (PLTs) may allow extended storage of PLTs as long as PLT quality is maintained.

Study Design And Methods: Twenty normal volunteers had their PLTs collected with an apheresis machine (Haemonetics Corp.).

Development and validation of radioligand binding assays to measure total, IgA, IgE, IgG, and IgM insulin antibodies in human serum.

Radioligand binding assays for total and Ig classes of insulin antibodies (IAB) were developed and validated. For each assay, insulin-extracted serum samples were incubated with radiolabeled insulin in the presence and absence of high levels of unlabeled insulin to determine nonspecific binding and total binding, respectively. To measure total IAB, antibody-bound insulin was precipitated with a polyethylene glycol solution, washed, and counted in a gamma-counter.
