The phrase "amount of background activity" is correct and usable in written English.
It can be used when discussing the level or quantity of activity occurring in the background of a system, process, or situation.
Example: "The amount of background activity on the server increased significantly during peak hours, affecting performance."
Alternatives: "level of background activity" or "quantity of background activity".
Non-identifiability would arise, say, if certain amount of background activity can be described as aftershock activity and vice versa.
It is also affected by the amount of background activity and background luminance as these have masking impact on possible blocking artifacts.
These results show that for the soluble C34V, the membrane-bound sTEVp has a lower amount of background activity, but lower inducible protease efficiency than the cytosolic sTEVp.
A whole-body PET/CT scanner with a clinical routine protocol was used for imaging the pellets inside of a cylindrical water phantom with increasing amounts of background activity.
To account for this phenomenon, we have also performed a set of experiments where the previous assays are repeated (with samples of 20, 10, 5, 2, and 1 spheroids and 2 × 105, 1 × 105, 5 × 104, 2.5 × 104, 1 × 104, and 5 × 103 cells in suspension and with successively increasing amounts of background activity levels) until no cell deposits are visible at PET scan.
In slow muscles the large amounts of background activity will dominate, and preclude a study of slow-to-fast transformation.
The presence of background activity surrounding a VOI, as seen in clinical situations, will result in variable amounts of spill-in which must be accounted for when applying any SPECT calibration.
The other source of background activity is the animal itself.
An EEG showed slowing of background activity with PSWC's.
Values for β-gal activity were corrected for differences in transfection efficiency first by subtracting the amount of background luminescence inherent in the β-gal and luciferase assays as determined by the RLU generated in lysates prepared from cells transfected with pBluescript SK+ alone, and then by adjusting the β-gal RLU in proportion to a set amount (2×10 RLU) of luciferase activity.
There's a certain amount of background noise at Poisson Rouge.
