Volume Rendering methods employing the GPU capabilities offer high performance on off-the-shelf hardware. In this article, we discuss the various bottlenecks found in the graphics hardware when performing GPU-based Volume Rendering. The specific properties of each bottleneck and the trade-offs between them are described. Further we present a novel strategy to balance the load on the identified ...

For solvency purposes insurance companies need to calculate so-called best-estimate reserves for outstanding loss liability cash flows and a corresponding risk margin for nonhedgeable insurance-technical risks in these cash flows. In actuarial practice, the calculation of the risk margin is often not based on a sound model but various simplified methods are used. In the present paper we properl...

This paper examines the choice of trading venue by dealers in U.S. Treasury securities to determine when services provided by human intermediaries are difficult to replicate in fully automated trading systems. When Treasury securities go “off the run” their trading volume drops by more than 90%. This decline in trading volume allows us to test whether intermediaries’ knowledge of the market and...

Run off the road crashes account for approximately 50% of motor vehicle related fatalities on a national and on a state level. To address this unacceptably high rate of fatalities this pilot project first sought to identify the primary factors associated with run off the road crashes and identify limitations and shortcomings of existing countermeasures. This was accomplished through the develop...

The enzyme predominantly used for in vitro run-off RNA synthesis is bacteriophage T7 RNA polymerase. T7 RNA polymerase synthesizes, in addition to run-off products of precise length, transcripts with an additional non-base-paired nucleotide at the 3'-terminus (N+1 product). This contaminating product is extremely difficult to remove. We recently characterized the single-subunit RNA polymerase f...

Motor vehicle crashes are one of the leading causes of death among young Americans. They also experience higher percentage of single vehicle, Run-off-the-road (ROR) crashes compared to other drivers. When looking at the methods of improving the alarming death rate of young drivers, it is important to identify the determinants of higher crash and injury severity. With that intention, the study d...

A monotonicity paradox occurs when a voting system reacts in a perverse way to a change in individual opinions. The vulnerability of a voting system to monotonicity paradoxes is defined as the proportion of voting situations that can give rise to such paradoxes. In this paper we provide analytical representations of this vulnerability in the three-alternative case for two voting systems, i.e. p...

They have fu ll time vice squads. | “ I have no sympathy at all for students apprehended and con­ victed o f selling drugs,” stated Roemer. “ People who break the law are on their own.” While Roemer may help a stu­ dent in trouble with local authori­ ties in other situations, he said he would not help in the case of drug violations. “ It would mess up his case i f 1 ...

I study electoral competition between established parties under threat of entry by a challenger under nonmajoritarian run-off elections. In contrast with classical majoritarian run-off elections, I show how nonmajoritarian rules can facilitate two-party systems, including those in which the established parties deter the challenger’s entry by adopting differentiated platforms. I also show that n...

OBJECTIVES To investigate the reliability of CT-angiography of the lower extremities (run-off CTA) to derive a treatment decision in patients with acute and chronic peripheral artery disease (PAD). MATERIALS AND METHODS 314 patients referred for run-off CTA were includ-ed in this retrospective study. First, diagnostic confidence of run-off CTA to derive a treat-ment decision was assessed in a...
