"stable activity" is a correct and usable phrase in written English.
It is commonly used to describe an ongoing and consistent level of activity or behavior. Example: The company's sales team demonstrated stable activity over the past year, consistently meeting their targets and bringing in steady revenue.
We demonstrate that, after its recovery simply by centrifugation, the insoluble polymer of Zera-Xyl is biologically active and shows stable activity for at least one month at room temperature.
The resultant MCs showed higher and more stable activity in methane decomposition reaction than commercial coal-based activated carbon and carbon black catalysts.
The glutardialdehyde-activated material displayed the highest initial immobilized enzyme activity and the most stable activity among all the support materials.
Although banking markets are more stable, activity levels have not yet returned to normal.
The growth in these regions compensate for stable activity in Australia and a slowdown in Canada.
In each case, different stable activity patterns can coexist over a substantial parameter range.
Importantly, this remarkable plasticity must be balanced by mechanisms that ensure stable activity at the level of neural circuits.
Here, biomass was constantly removed with a rate of 120 ml day−1 from each bioreactor, all of which had stable activity and growth rate (Fig. 1).
Networks with continuous attractor properties can maintain a stable activity state over time; however, the possible states are not discrete as in attractor networks but can vary continuously.
Thus, stable activity for photocatalytic water decomposition was not observed over thin-layered Ta2O5/SBA-5.
High dispersion of metallic Co species stabilized on SiO2 was responsible for stable activity.
