The edge detection methods could detect the variation of gray levels, but it is sensitive to noise and may suffer from the focusing artifact.
Other motion-compensation techniques, including the use of a pressure belt registering the movements of the chest [ 16], the detection of the variation of the ECG amplitude during respiratory events [ 25] and, more recently, the application of navigator signals, which sense the displacement of the diaphragm [ 26, 27], have shown a good reproducibility.
In a sensitivity analysis, both case detection rate and the variation of R0 have major effects on the resulting delay.
To avoid systematic errors, I previously determined the range of linearity of the detection system by the variation of the light intensity via fluorophore concentration [ 35].
However, in the case of short-term missing of small aftershocks, the variation of detection is usually unknown.
It has been experimentally verified that the proposed detection procedure is robust to the variation of parameters and.
And finally, due to the variation of analytical detection limits, we limited our data to the NHANES 2003-2004 cycle, which had the lowest detection limits.
We developed a method of origin detection based on the variations of microarray ratios restricted to the first 5 min after the beginning of S-phase.
We used 1996 as the reference year, allowing in this way the detection of the variations in the causes of death from 1996 through 2000.
Although no archaeal genome sequences of the same species are currently available, for 33 bacterial species there are two or more genome sequences available (Additional File 2), allowing the detection of variation of δ* of genome sequences from the same species.
The detection of variations of the rock density at shallow depths, like those due to lava conduits or dykes, calls for an improvement of the measurement resolution by one order of magnitude.
