The phrase "absence of variability" is correct and usable in written English.
It can be used in contexts where you want to describe a situation or condition where there is no variation or change in a particular aspect.
Example: "The experiment showed an absence of variability in the results, indicating that the conditions were stable throughout the testing period."
Alternatives: "lack of variation" or "no variability present".
Comparison of ECa data sets obtained under inundated and dry conditions showed that the ECa measurements under inundated condition (ECa-i) were more strongly related to soil properties due to the absence of variability in soil moisture and the increased stability of the floating sensing platform.
This was associated with a complete absence of variability (diurnal and movement/feeding related) in the individual VO2 traces.
Thus the absence of variability in the minimal model of the circuits can be explained.
Indeed, there was no correlation in this study between brain BE levels and plasma testosterone concentrations, although this research is limited by the absence of variability of BE or testosterone concentration between the 11 inbred strains.
In addition, positions corresponding to singleton amino acids Methionine and Tryptophan (with a natural absence of variability) were excluded.
Despite the use of image smoothing and absence of variability associated with VOI delineation, primary tumour SUVmax was less reproducible (SD 12.6%%) than SUVmean.
This hypothesis is confirmed for domesticated cowpea by the near-absence of variability in its populations as well as the absence of some of the alleles encountered in wild cowpea (Amp4 91 and especially Amp2 100 ).
Since no functional analysis was performed, we cannot formally rule-out a TLR4-mediated variability in clinical response, but in the absence of genomic variability this is unlikely to be the case.
An absence of such variability actually indicates that experimental replications are invalid, perhaps because of a bias to suppress contrary findings or because the experiments were run improperly.
The absence of extreme variability in δpore ice suggests that each pore ice sample represents a multi-year seasonal blend of precipitation, whereby weather-related fluctuations in δprecip are attenuated through the mixing of precipitation from several warm-season months, and multiple years facilitated by repeated freeze thaw cycles.
Among the 21 probes, 2 probes are shared by more than one species due to low or absence of sequence variability, i.e. Rpam for Rhizopus azygosporus/Rhizopus microsporus and Fumop for Fusarium moniliforme/Fusarium oxysporum/Fusarium pallidoroseum.
