The phrase "are determined and validated" is correct and usable in written English.
It can be used in contexts where you are discussing processes or methods that have been established and confirmed as accurate or effective.
Example: "The results of the experiment are determined and validated through rigorous testing procedures."
Alternatives: "are established and confirmed" or "are assessed and verified."
Its limiting mixture design values could be determined and validated.
The X-ray complex structure was determined and validated our design rationale.
The X-ray co-crystal structure of EGFR with a close analog (17) was determined and validated our design rationale.
The X-ray co-crystal structure of EGFR with 37 was determined and validated our design rationale.
SFE curves were modeled using well-known mathematical models from literature, and mass transfer coefficients were determined and validated through correlations with dimensionless numbers.
Using the results of the numerical model, the rate of air discharge through the vent was determined and validated by available experimental data.
Although thresholds for safe treatment should be determined and validated in large patient series, the potential of hepatobiliary scintigraphy to quantify segmental liver function, in contrast to overall liver function, seems imperative for RE treatment planning.
Following an integrated optimization process, cost-effective bioethanol production conditions from whole-slurry E. globulus wood were determined and validated experimentally, representing a step-forward towards its industrial implementation.
Based on regression analysis of the experimental results from central composite design in response surface models, two second-order polynomial models adequately representing the relationship between these variables and EPS TEAC and yield were obtained, and the optimum concentration of these variables were determined and validated.
The steric and electrostatic contributions from the contour map were interpreted from the color-coded contour plots generated from the PLS model and the active structural components for potency against C. neoformans were determined and validated in the test set compounds.
