Previous studies comparing ACD measurements obtained by optical and contact ultrasonic instruments reported small differences between different optical techniques (< 5%), yet larger differences (10 15%) have been reported with different contact ultrasonic techniques [ 23, 24].
For sclerotic dentin, SM techniques had a small difference, while large effects sizes were measured for comparisons with MR techniques.
In order to compare spectra between samples, several normalization techniques were tested to eliminate small differences in the absolute relative reflectance of similar spectra.
By also placing them in precisely arranged arrays, he employs a very sensitive technique called interferometry to measure small differences in the arrival times of the radiation photons, thereby greatly increasing the information they provide.
However, the technique was developped to detect small differences in complex data sets so it could probably detect differences more subtle than between the two Yersinia species, although it would probably give lower percentages of inertia for each axis.
All of these donors underwent a surgical HPx, but it is unclear whether small differences in technique among surgeons could play a role in donor outcomes.
Accuracies of atomic clocks and modern observational techniques are so high that the small differences between classical mechanics (as developed by Newton in the 17th century) and relativistic mechanics (according to the special and general theories of relativity proposed by Einstein in the early 20th century) must be taken into account.
During this process, we will rely on extensive simulation efforts because the controlled environment of a wireless network simulator enables us to observe small differences in applied techniques and parameter values.
They then studied cells from these individuals, using sophisticated genetic engineering techniques that can identify even very small differences between nearly similar stretches of DNA, or deoxyribonucleic acid, which encodes genetic information.
Quantitative techniques may also be useful in detecting small differences in clearance.
Small differences between the two techniques with respect to the durations of these phases and the total daily lengths of these behaviours were not statistically significant.
