By comparing two extreme phenotypic groups – short sleepers and long sleepers – we are investigating whether inter-individual differences in sleep duration have a neurobiological basis in stable trait disparities in homeostatic and circadian sleep regulatory systems.
The cross window is constructed with the same method in section B, and the disparity of stable pixels with maximum number in this area is selected to replace it.
NHANES data from 2003 through 2010 were chosen for the analysis because hypertension disparities remained stable between racial/ethnic groups over these years (4) and because survey questions about risk factors for high blood pressure were consistently asked among these survey waves.

These disparities were generally stable and persistent over the study period.
The overall prevalence will change from region to region, but the socioeconomic pattern will probably always be the same, pointing to the fundamental problem that these disparities are very stable and that they can hardly be changed by single, short-term interventions.
Unlike intensities, disparity values are generally stable over time regardless of changes in lighting.
Switzerland prides itself on being ultra-competitive but also on being a socially stable country without the extreme class disparities seen elsewhere.
It is only a fall in unemployment in Germany that has kept the euro area's overall level stable (see chart).As the downturn deepens, this disparity between Germany and the rest is likely to widen.
For telecoms companies, despite stable revenue as a whole, there was wide disparity among segments.
