In several cases we obtained a significant loss of the entrapped dye above the background level.
The current version of 'csmooth' considers only positive deviations from the background level, i.e. emission features.
Moreover, efforts to calculate the background level of high-energy particles in the galaxy are beset with messy uncertainties.
The background level corresponds to a radiocarbon age of 40,000 years.
Different aesthetic objects display different articulations of the background level.
It approached the background level after 48 h (Fig. 5B).
What no one did was look "at the background level of systems falling over", he suggests.
The background level exists only for the subject who grasps it.

I've written, here and there, about how the brain copes and how to dial down the background level of stress.
