The phrase "a robust and constant" is correct and usable in written English.
It can be used to describe something that is strong, reliable, and unchanging over time.
Example: "The system provides a robust and constant support for all users, ensuring seamless operation."
Alternatives: "a strong and steady" or "a reliable and unchanging".
A robust and constant decrease in the latency to the onset of slow wave sleep (SWS) was detected throughout the five days of recording in both light [F(22.16) = 72.46, p<0.0001] and dark [F(22.16) = 75.0, periods1] periods.
The data indicated that a 50% dopaminergic neuronal loss restricted to the SNpc, inflicted by MPTP, was able to produce a robust and constant decrease in the latency to the onset of SWS during the 5 days of recording in both light [F(22.16) = 72.46, p<0.0001] and dark [F(22.16) = 75.0, periods1] periods (Fig. 3a).
In the tumors we describe, there are more luminal cells than basal cells, and this proportion is robust and constant (upon transplantation).
Neither apologetics nor xenophobia, but a robust commitment to a robust and pluralistic democracy.
To establish a robust value for constant w ((9)), the precision and recall rates were computed for values of w between 1.8 and 4.0 with a step of 0.8.
A robust constant thrust rendezvous approach under thrust failure is proposed based on the relative motion dynamic model.
In the worst case of a total failure of all 6 sensors, a robust constant longitudinal control law is employed which ensures a basic longitudinal control performance.
The changes due to hyperventilation with probe pressure were more robust and relatively constant across the range of pressures measured, i.e., when compared to the changes obtained with minimal probe pressure.
Terrorism remains a grave and constant threat.
Amidst a green forest covering the hills, a robust stream delivers a constant supply of clear water.
Moreover, our results reveal that the nature of buffering and release of variation by Hsp90 is not deviated from general features of a robust system in which constant phenotypes are achieved or disrupted by regulating network hubs.
