After adjustment for body mass index, differences in mammographic density did not differ between African-American and Caucasian women (Table 1).
Throughout the imaging process, the samples were kept immersed in water to eliminate refractive index differences in the optical medium.
This may be especially true of measures of functional connectivity or coherence between brain areas, as these may most powerfully index differences in network function that affect psychopathology.
Table 2 summarises the results of our search for meta-analyses of genetic variants, indexing differences in the risk markers of interest.
Thus, we tested the contrast (Treversal − 1− Treversal) across salient/null blocks in the placebo group, which indexes differences in neural activation for trials with expected outcomes Treversal − 1 compared with unexpected outcomes cueing reversal Treversal.
However, the benefit of exploiting refractive index differences in x-ray imaging of weakly absorbing airways tissue could already be demonstrated in vivo at the synchrotron (Lewis et al., 2005).
36 If treatment groups had had a similar baseline body mass index, differences in outcomes could have been more apparent (pregnancy induced hypertension, severe neonatal hypoglycaemia) or become significant (pre-eclampsia, birth weight, large for gestational age, any neonatal hypoglycaemia).
The studies selected used a variety of principal summary measures (e.g., technical efficiency scores, Malmquist Productivity Index, difference in costs).
The amylose and amylopectin chains are arranged radially within the granule and the density and refractive index difference in crystalline and amorphous structure show the anisotropy and generates birefringence when observed with a microscope under polarised light [15 17].
Instead of a linear mapping, Tronçon et al. proposed to compute an m-dimensional mapping window for each m-dimensional array [11]: the sides of a window were computed based on the maximal index difference in each dimension between array elements simultaneously alive.
