This procedure hardly reflects the major sources of experimental variability, namely, differences in growth densities and lysis efficiency.
There is then another level of neural variability, namely, trial-to-trial variations in the firing rates themselves.
While tumor SUR thus is not affected by inter-study variability of blood SUV, its use does not address another source of potentially serious variability, namely, insufficient standardization of the uptake time prior to scanning.
In the NN training, validating and testing processes, five factors which are well known to influence TEC variability namely diurnal variation, seasonal variation, magnetic activity, solar activity and the geographic position of the GPS receivers were included in the NN model.
While some models include only the moment-by-moment variability discussed above, others include a second source of variability, namely between-trial variability in the strength of the sensory evidence reaching the accumulators.
It indeed removes some task-independent sources of variability, namely overall level and ILDs.
It cannot be excluded that reproducibility would be lower when another source of variability, namely interobserver variability, would be added.
This method is based on the fact that recent positive selection leaves a strong footprint on the pattern of haplotype variability, namely extended linkage disequilibrium.
We also correlated variability with other factors that have been reported to affect variability, namely GC content and gene density [ 15], and results are in Table 2.
