An inversion algorithm is used to calculate the gas vertical distribution from ground based column amount measurements so that the gas content in stratosphere and troposphere is evidenced.
Because FL and RL levels increase linearly with cell amount, measurements of FL and RL expression could provide a more quantitative assessment of cell invasion.
SDD values provide information about the size of the error related to a measured value and in the amount of measurement error that should be taken into account when comparing two consecutive measurements.
These procedures were conducted using the package "shapes" in R. To estimate the amount of measurement error resulting from digitization, replicate measurements were made on a set of 24 O. excavata individuals and 16 T.
As the CI and MDC represent boundary for true score and boundary for change, respectively, change could not be regarded as 'real' if the amount of measurement error around the true score exceeded the amount of measurement error around the change score.
Based on repeat measurements of a random subset of 30 individuals, the amount of measurement error because of imaging and digitizing was negligible (forewing length repeatability = 95.2%, P < 0.0001 and wing surface area measures repeatability = 99.95%, P < 0.0001).
While we attempted to limit the amount of measurement error by obtaining data from two sources (WHO and WDI), measurement error is inevitably present and our inferences should be viewed in light of this limitation.
In fact, though, there is a growing recognition among those dealing most closely with the issue that the term digital divide, while clever and provocative, has become a catchall phrase for politicians with conspicuous agendas and that the divide is a complex phenomenon that no amount of measurement can fully explain.
