A role for the cortex in sleep-wake regulation.

Abstract: Cortical and subcortical circuitry are thought to play distinct roles in the generation of sleep oscillations and global state control, respectively. Here we silenced a subset of neocortical layer 5 pyramidal and archicortical dentate gyrus granule cells in male mice by ablating SNAP25. This markedly increased wakefulness and reduced rebound of electroencephalographic slow-wave activity after sleep deprivation, suggesting a role for the cortex in both vigilance state control and sleep homeostasis.

An efficient denoising algorithm for global illumination

Abstract: We propose a hybrid ray-tracing/rasterization strategy for realtime rendering enabled by a fast new denoising method. We factor global illumination into direct light at rasterized primary surfaces and two indirect lighting terms, each estimated with one path-traced sample per pixel. Our factorization enables efficient (biased) reconstruction by denoising light without blurring materials. We demonstrate denoising in under 10 ms per 1280×720 frame, compare results against the leading offline denoising methods, and include a supplement with source code, video, and data.

Searching for dilepton resonances below the Z mass at the LHC

Abstract: We consider LHC searches for dilepton resonances in an intermediate mass range, $\ensuremath{\sim}10--80\text{ }\text{ }\mathrm{GeV}$ We adopt a kinetically mixed ${Z}^{\ensuremath{'}}$ as an example of weakly coupled new physics that might have evaded detection at previous experiments but which could still be probed by LHC dilepton spectrum measurements in this mass range Based on Monte Carlo simulations, we estimate that existing data from the 7 and 8 TeV LHC could be used to test values of the kinetic mixing parameter $\ensuremath{\epsilon}$ several times smaller than precision electroweak upper bounds, provided an appropriate analysis were carried out by one of the experimental collaborations

Computer-Animated Displays and the Jury: Facilitative and Prejudicial Effects

Abstract: Two experiments assessed the effects of computer-animated displays on mock jurors. In both, participants watched a trial involving a dispute over whether a man who fell to his death had accidentally slipped or jumped in a suicide. They watched a proplaintiff or prodefendant version in which the body landed 5–10 feet or 20–25 feet from the building. Within each condition, the distance testimony was presented orally or with an animated display. When the tape depicted the event in a neutral manner, judgments were more consistent with the physical evidence. But when the plaintiff and defense used the tape to depict their own partisan theories, participants increasingly made judgments that contradicted the physical evidence. Results suggest that computer-animated displays have greater impact than oral testimony. Whether that impact is to facilitate or mislead a jury, however, depends on the nature of the display.
