SRT dividers are common in modern floating point units. Higher division performance is achieved by retiring more quotient bits in each cycle. Previous research has shown that realistic stages are limited to radix-2 and radix-4. Higher radix dividers are therefore formed by a combination of low-radix stages. In this paper, we present an analysis of the(More)
—Domino circuits are widely used in high-performance CMOS microprocessors. However, textbook domino pipelines suffer significant timing overhead from clock skew, latch delay, and the inability to borrow time. To eliminate this overhead, some designers provide multiple overlapping clock phases such that domino gates are always ready for evaluation by the(More)
Aesthetic plastic surgery has been long practiced for primarily psychological rather than physical benefit to patients. However, evaluation of the psychological impact of aesthetic plastic surgery has often been of limited methodological rigor in both study design and appropriate measurement. This study is intended to evaluate the psychological impact of(More)
The prototypic endocannabinoid, anandamide, and synthetic analogues have been shown to elicit pressor and depressor effects, bradycardia, vasorelaxation, and inhibition of neurotransmission in the central and peripheral nervous systems. Cannabinoid-mediated inhibition of neurotransmission is mediated by inhibition of voltage-gated Ca(2+) channels and(More)
—Clock skew is an increasing concern for high-speed circuit designers. Circuit designers use transparent latches and skew-tolerant domino circuits to hide clock skew from the critical path and take advantage of shared portions of the clock network to budget less skew between nearby elements than across the entire die, but current timing analysis algorithms(More)
OBJECTIVES To develop a psychometrically robust and widely applicable short form of the Derriford Appearance Scale, (DAS59), which (1) will reliably and validly assess the distress and difficulties experienced in living with problems of appearance, (2) is acceptable to clinical and non-clinical populations, and (3) facilitates research and clinical(More)
BACKGROUND The TAM-receptor tyrosine kinase family, Tyro3, Axl and Mer are key to apoptotic cell clearance. Reduced phagocytic clearance in systemic lupus erythematosus (SLE) leads to prolonged exposure of nuclear autoantigen to the immune system. Here we measure the levels of TAM receptors and the phagocytic capacity of monocytes and macrophages in(More)
This paper describes the input/output subsystem that is provided with the Hawk operating system kernel and the SANDAC V computer. Hawk and the SANDAC V were designed for embedded hard real-time applications. The IOS is a hierarchically organized set of modules t h a t can be configured to match the requirements of a specific real-time application. It was(More)
A coustic energy can precisely and accurately eject a droplet of liquid from a reservoir, enabling delivery of picoliter and nanoliter volumes low nanoliter volumes between microplates using focused acousticsdautomation considerations. Acoustic droplet ejection has been shown to be extremely precise (coefficients of variation !2%) over a wide range of(More)
