The phrase "activity threshold" is correct and usable in written English.
It can be used in contexts related to measuring or defining a limit or level of activity, often in fields like health, fitness, or research.
Example: "To improve your fitness, it's important to identify your activity threshold and gradually increase your exercise intensity."
Alternatives: "activity limit" or "activity level".
Since different targets have different activity value ranges, the minimal activity threshold to locate an active set was computed as the average of the negative logarithmic activity values (i.e., ({log}} {Ki}) or ({log} {IC50})) plus one standard deviation above that activity value for each target.
The activity threshold defines a certain velocity limit to distinguish active from inactive behavior (1 cm/s).
Additionally, it represents an activity threshold that is more relevant for biological activity.
Indeed, using an activity threshold of 6.5 log units appears to improve performance.
Activity-based estrus alerts were initially identified using the default activity threshold value recommended by the manufacturer, but a range of activity threshold values was then analyzed to determine their effect on estrus detection performance.
A reference NB model with an activity threshold of 10 μM was included using PP and default setup.
Active brain regions were defined as regions with more than one active voxel with significant positive BOLD activity (thresholded at z = 2.3 with a corrected cluster significance level of p < 0.05).
It incorporates both basal and induced pathway activation and is more relevant in measuring pathways regulated by activity thresholds.
Secondly, MAPK activity thresholding has been suggested as a possible mechanism for differential gene activation [5].
However, to investigate the influence of different activity thresholds, three SEA models were constructed with activity thresholds of (10), (1) and (0.1 upmu {text{m}}), respectively.
Two sets of 2D molecular descriptors (P_VSA and BCUT) were used to build models using different biological activity thresholds.
