Each sample was analyzed twice to confirm reproducibility in identifying the differentially expressed proteins and to ensure stability of instrument performance.
Regarding the stability of instrument, the mean time between administrations of the GAD-2 and the GAD-7 was 5.9 days (SD = 2.11).
The true stability of a phenomenon is often only implicitly assumed, and the observed stability characteristics of instruments are often ignored.
These discrepancies probably have several origins: the Earth's atmosphere, the spectral domain of observation, the stability of the instruments, and the data filtering techniques used.
In addition, we monitored the stability of the instruments using 1 ppb of Re and Rh as internal standards and the GSR-5, GSR-6, and GSD-9 standards for blanks and standardization.
The F differences in this case compares daily mean values of F derived from the H and Z baseline corrected fluxgate measurements against those derived from PPM measurements, providing vital information on the longer term stability of the instruments.
From 1865, he worked on improving the elegance and stability of surveying instruments, especially the theodolite, whose construction he simplified.
They also show the stability of the instruments employed, which adds to their potential for comparative use (in 22 evaluations, only one registered a comparatively substantial difference, i.e., the 2008 score by SPs at T0, when compared with their 2009 score at T0).
The stability of the instrument was between 0.836 and 0.402.
The test-retest method with a weighted Cohen's kappa showed a good stability of the instrument.
Special attention was given to the time resolution and the stability of the instrument performance under driving conditions.
