Further experiments are underway to characterize the causative locus or loci, and preliminary analyses indicate two genes involved in dolichol/dolichyl biosynthesis may be contributing to the skewing difference, possibly by changing cell wall composition.
Finally, the difference in pharmacy costs observed (higher pharmacy costs among controls) may have skewed differences in total all cause costs between cases and controls due to a higher prevalence of contraindications to interferon-based treatment among patients with HCV and ALD.
This is the first infinite family of non-abelian skew Hadamard difference sets.
We then give a construction of skew Hadamard difference set in the group G for each prime p>3 that is congruent to 3 modulo 4.
Third, two skew exponential difference schemes are proposed to raise the solution accuracy in multidimensional problems: one is designed to be free of numerical diffusion and the other with minimum numerical diffusion to ensure solution monotonicity.
Owing to skew distributions, differences between means were tested with of the Mann Whitney U test.
The former compares differences in total expression assuming that other types of biological regulation and environmental factors acting in trans, will not mask or skew the differences in gene expression between the possible allelic combinations.
McPeek and Sun (2000, p. 1079) point out that although the sampling distribution of log likelihood ratios for two fixed relationships is often close to a normal distribution (as we have shown previously; Figure 2, Appendix Tables A11 and A12), the sampling distribution of the maximized version tends to be skewed (the difference is between the estimate of R fixed or varying from sample to sample).
imax amplitudes, however, might still be skewed by differences in fibre sizes, as indeed many mdx fibres were smaller than wt fibres [25].
However, the GC content is independent of the GC and TA skews, and differences between the leading and the lagging strands cannot account for variations in the GC content.
Thus, the results obtained with intrinsic imaging are unlikely to be skewed by differences in brain perfusion related to distinct anatomical organizations of the cortical vasculature in reeler and WT.
