Values of the intron expression statistic calculated from these arrays suggest that technical variation as well as variation between cell passages make a contribution to the observed differences between arrays (Fig. 1a); nonetheless, the difference between cell lines was highly statistically significant, despite the variation between repeats (p = 1.0×10−5, from a two-tailed t-test).
At very low energies there is a contribution from variation in the grating periods.
We estimated mortality due to influenza using regression models that expressed weekly deaths as the sum of a regular seasonal component of variation, a long-term trend, a contribution from each of the influenza types, a component related to meteorological conditions, and an error term.
Given short timescales for power variations, bioenergy plants can make a contribution both to grid stabilisation (with < 15 min reaction time) and the balancing of residual load (> 15 min reaction time).
That is because Sky charges the broadcasters to access its electronic programmme guide, and asks for a contribution to provide regional variations where necessary.
The variation in contribution with operating conditions is estimated using the cluster renewal mechanistic model.
The variation in contribution from Fe NOM and Fe (hydr oxides was controlled by pH and total concentrations of NOM.
Using techniques that measure overall variation, frequency contribution, scale-invariant variation and degree of disorder, altered variability in consistently present in illness states, and the degree of alteration provides a measure of prognosis.
Spectrophotometry measurements showed a strong variation of contributions in the UV vis bands, both in the yellow chromophores region and in the carbonyl formation region, which was consistent with the hypothesis that a predominant oxidation mechanism is involved.
Although many of these candidate genes were cloned earlier with mutational studies, identifying their allele variation contribution to overall phenotypic variation among diverse natural accessions is critical.
