Static power dissipation is a concern for battery powered hand-held devices since it can substantially impact the battery life. Here, the use of reverse body bias to limit I<inf>off</inf> on the high performance, low power XScale&#8482; microprocessor core is described. The scheme utilized is amenable to implementation on a low-cost (non-triple well)(More)
A 90 nm ARM/spl trade/ V5TE compatible microprocessor core intended for high performance and low power embedded applications is described. The core includes an ECC protected 2 level 512 MB cache, high-bandwidth single-cycle L1 cache line fill and evict, and cache coherency. Circuit design for high speed and low power are described, as well as their impact(More)
Handheld and other battery-powered ICs require process scaling to increase functional integration and reduce active power consumption. Scaling also increases leakage current components to the point where standby power is frequently a limiting design factor. A scheme combining low-leakage thick-gate shadow latches and high-performance transistors is(More)
Background—Native and oxidized LDLs (n-LDL and ox-LDL) are involved in the atherogenic process and affect endothelium-dependent vascular tone through their interaction with nitric oxide (NO). Methods and Results—In this study we evaluated directly, by using a porphyrinic microsensor, the effect of increasing lipoprotein concentrations on endothelial NO and(More)
Hormonal changes in humans during spaceflight have been demonstrated but the underlying mechanisms are still unknown. To clarify this point thyroid and testis/epididymis, both regulated by anterior pituitary gland, have been analyzed on long-term space-exposed male C57BL/10 mice, either wild type or pleiotrophin transgenic, overexpressing osteoblast(More)
Static power dissipation is a concem for battery powered hand-held devices since it can substantially impact the battery life. Here, the use of reverse body bias to limit IM on the high performance, low power XScaleTM microprocessor core is described. The scheme utilized is amenable to implementation on a low-cost (non-triple well) process and has limited(More)
We investigated the presence of nitric oxide synthase (NOS) in brain of adult Antarctic teleosts by indirect immunofluorescence technique using a synthetic rat neuronal NOS (nNOS) antibody. The following species were examined: Trematomus bernacchii, Gymnodraco acuticeps, Histiodraco velifer, Cygnodraco mawsoni (haemoglobin-rich), Chionodraco hamatus and(More)
In the Antarctic Ocean salt concentration differs from the bottom to the surface owing to the seasonal forming and melting of sea ice. Antarctic teleosts present different lifestyle from benthic to pelagic. While benthic animals face a constant seawater salinity, benthic–pelagic animals have to face different salt concentration. Branchial morphology and(More)
The distribution of Phe-Met-Arg-Phe-NH2 (FMRF-amide) -like immunoreactivity was investigated by indirect immunofluorescence technique using the molluscan FMRF-amide antibody in the brain of icefish (Pagetopsis macropterus and Chionodraco hamatus used as positive control) and red blooded (Trematomus bernacchii, Gymnodraco acuticeps, Histiodraco velifer,(More)
