Ubiquitous Relaxation in Bti Stressing—new Evaluation and Insights
نویسندگان
چکیده
The ubiquity of threshold voltage relaxation is demonstrated in samples with both conventional and high-k dielectrics following various stress conditions. A technique based on recording short traces of relaxation during each measurement phase of a standard measure-stress-measure sequence allows monitoring and correcting for the otherwise-unknown relaxation component. The properties of relaxation are discussed in detail for pFET with SiON dielectric subjected to NBTI stress. Based on similarities with dielectric relaxation, a physical picture and an equivalent circuit are proposed.

Binding-time Improvement and Fold/Unfold Transformation
Binding-time improvement (BTI) is an important preliminary stage in partial evaluation. Some BTI rules can be automated, but the state of the art is that many improvements are still made \by hand" using an ordinary text editor. Mechanically assisted fold/unfold transformation could provide a more systematic framework for BTI.
متن کاملA survey of intracranial blood flow velocity in thalassemia intermedia in Khuzestan Province, Iran
Background: Beta-thalassemia intermedia (BTI) is a type of hemoglobinopathy with an increased risk of cerebrovascular accidents, and transcranial cerebral Doppler ultrasonography (TCD) through determining the mean cerebral blood flow velocity (CBFV) can serve to predict the risk of a developing stroke. This study aims to compare patients with beta-thalassemia intermedia and healthy individuals ...

متن کاملExposure and preventive measure to reduce high and daily exposure to Bacillus thuringiensis in potted plant production.
The bacterium Bacillus thuringiensis (Bt) is the active organism in a variety of commercially available products used worldwide as biopesticides. Bt products are applied in large outdoor areas as well as in indoor environments. Even though it has been sold for decades, not much is known about the occupational exposure to Bt. The aim of this study was to obtain knowledge about the exposure to Bt...
متن کاملAn evaluation of Gambusia affinis and Bacillus thuringiensis var. israelensis as mosquito control agents in California wild rice fields.
The mosquito control potential of the mosquitofish and Bacillus thuringiensis var. israelensis (Bti) were evaluated in experimental wild rice fields in Lake County, California. Fields were assigned one of six treatment: control, 1.1 kg/ha G. affinis, 3.4 kg/ha G. affinis, Bti only (6 kg/ha Vectobac granules), 1.1 kg/ha G. affinis plus Bti and 3.4 kg/ha G. affinis plus Bti. Gambusia affinis, at ...
