TL;DR: Significant advances have been achieved for realtime ray tracing recently, but realtime performance for complex scenes still requires large computational resources not yet available from the CPUs in standard PCs.
Abstract: Significant advances have been achieved for realtime ray tracing recently, but realtime performance for complex scenes still requires large computational resources not yet available from the CPUs in standard PCs. Incidentally, most of these PCs also contain modern GPUs that do offer much larger raw compute power. However, limitations in the programming and memory model have so far kept the performance of GPU ray tracers well below that of their CPU counterparts. In this paper we present a novel packet ray traversal implementation that completely eliminates the need for maintaining a stack during kd-tree traversal and that reduces the number of traversal steps per ray. While CPUs benefit moderately from the stackless approach, it improves GPU performance significantly. We achieve a peak performance of over 16 million rays per second for reasonably complex scenes, including complex shading and secondary rays. Several examples show that with this new technique GPUs can actually outperform equivalent CPU based ray tracers.

TL;DR: Pooled analyses suggest that MET with alpha-blockers or calcium channel blockers augments stone expulsion rates, reduces the time to stone expulsion, and lowers analgesia requirements for ureteral stones with and without ESWL for stones < or = 10 mm.

TL;DR: Analysis of the first- and second-order coherence before and after wavelength conversion clearly proves that pivotal properties, such as the coherence time and photon antibunching, are fully conserved during the frequency translation process.
Abstract: We demonstrate efficient ($g30%$) quantum frequency conversion of visible single photons (711 nm) emitted by a quantum dot to a telecom wavelength (1313 nm). Analysis of the first- and second-order coherence before and after wavelength conversion clearly proves that pivotal properties, such as the coherence time and photon antibunching, are fully conserved during the frequency translation process. Our findings underline the great potential of single photon sources on demand in combination with quantum frequency conversion as a promising technique that may pave the way for a number of new applications in quantum technology.

TL;DR: Recombinant plasminogen activator given as a double bolus of 10 + 10 MU achieves more rapid, complete, and sustained thrombolysis of the infarct-related artery than standard-dose TPA, without an apparent increased risk of complications.
Abstract: Background Early restoration and maintenance of normal (TIMI 3) blood flow during acute myocardial infarction is critical for optimal preservation of left ventricular function and survival. Recombinant plasminogen activator (r-PA, reteplase) is a nonglycosylated deletion mutant of wild-type tissue-type plasminogen activator (TPA) that has been shown to achieve more rapid and complete thrombolysis compared with other plasminogen activators in animal models. Methods and Results The RAPID Trial was designed to test the hypothesis that bolus administration of one or more dosage regimens of r-PA was superior to standard-dose alteplase (TPA) in achieving infarct-related artery patency 90 minutes after initiation of treatment. Six hundred six patients with acute myocardial infarction were randomized to one of four treatment arms: (1) TPA 100 mg IV over 3 hours, (2) r-PA as a 15-MU single bolus, (3) r-PA as a 10-MU bolus followed by 5 MU 30 minutes later, or (4) r-PA as a 10-MU bolus followed by 10 MU 30 minutes ...
