Thus, linear extrapolation to zero domain wall velocity (see Figures2 and5) gives negative values of the critical propagation field, H0.
For 2′-methoxyisoflavans, R-/S-form result in positive/negative specific rotation values, respectively, but for 2′-hydroxyisoflavans, R-form gives negative values [14, 17, 20, 21, 22, 23, 24, 25].
Fingers' flexion was assigned positive values whereas fingers' extension was given negative values with respect to the baseline.
The relative heterozygosity was normalized in a way that gives negative values when cases are less heterozygous than controls and otherwise positive values.
Linear fold change values (f.c). of gene expression are given; negative values represent a down regulation.
Mutants exhibiting growth defects were given negative values while mutants showing enhanced growth were given positive values.
Fold changes between pair-wise comparisons are given (negative values indicates a lower value in the mutant).
A direct approach can be used, which although straightforward does not allow estimates of error and can give negative values of the fluorescence per cell.
For genes on the reverse strand, the RNA-seq data are given negative values and are shown in red instead of black, and the genome position numbering is reversed.
For example, an excess of rare alleles, giving negative values of Tajima's D and Fu & Li's D* and F* statistics, may actually result from a sudden population expansion rather than from the effects of positive selection (Ptak and Przeworski 2002; Nielsen et al. 2005).
