Procedures such as using control groups to test the effect of treatments, sampling procedures to make sure what you are measuring/observing is representative of the larger population, double-blind studies to eliminate any chance of bias, and establishing the precision of measurement are examples of how scientists go about studying nature.
This injection QC was used for monitoring the overall performance of the LC-MS system and for establishing the precision of the analytical method, but not for correction of intensities.
Liner stability within the shell was reported in 2 ways: (1) the liner segment compared to the shell-only segment, and (2) the liner compared to the pelvis segment. 2 sets of RSA images (double examinations) were captured at least once for each patient at the same visit, to establish the precision of each measurement method.
This approach provided N0 - 1 degrees of freedom in estimating the experimental error, and at the same time established the estimation precision of the OF (biohydrogen production rate) around the central experimental point.
Correlations were made between diagnostic tests (ELISA, qPCR, culture and histopathology) to establish the precision and predictive values of individual tests.
The results of the autocorrelations to establish the reliability (precision of a single measurement or extrapolation back to zero lag) and stability (variation with time not related to seasonality) of the 48-h dietary intakes are shown in Figure 3 A. In addition, repeatability of measurements on 2 consecutive days ranged between 40.1% and 60.1%.
The interday variation of eugenol at three different concentration levels of 20, 100, and 600??g?mL?1 establishes the intermediate precision of the method.
An intuitive model was established to simulate the precision of the sequence-controlled copolymerization with DPE derivatives based on investigations of end-capping kinetics.
Using a newly established criterion, based on the precision of miRNA processing from precursors, we identified 66 novel miRNAs in maize.
And the PSO algorithm is used to tune the parameters of SVM and improve the precision of established model.
