There is evidence from familial aggregation, transmission patterns, and twin studies that AD has a substantial genetic component that has an estimated heritability of 58%to79%9% [ 4], and the lifetime risk of AD in first-degree relatives of patients may be twice that of the general population [ 5].
Moreover, pain is a subjective sensory symptom; it is difficult to measure; and there are substantial psychological and emotional components that contribute to the perception of pain [ 19].
We have shown that in a standard mid-course multiple-choice examination paper a substantial component of that examination will focus on testing higher cognitive skills.
Direct regressions of chemical species in time-series models were limited either to a few chemical components that explained a substantial amount of PM2.5 mass (Peng et al. 2009) or to the analysis of multiple cities using earlier data.
As mentioned earlier, CG dinucleotides are very mutable and polymorphic, which is a problem for microarray designs that include a substantial component of CGs that represent known common SNPs [ 118, 119].
Combining this observation with normal performance in the visual watermaze suggests a complex interaction between the difficulty of the task and a substantial motivational component that underlie their lack of spatial acquisition, with the possibility that muscular weakness also contributes to apathy.
Therefore, our analyses suggest that for Genotype 1 of HCV, a substantial component of clearance that is not due to the IL28B genotype is likely to be explained by the similarity of viral sequences infecting the host.
Reflectance measurements performed below these thresholds collect a substantial component of light that has undergone few, or single, scattering events, making the probability of collecting light in that regime (at least somewhat) dependent on the backscattering features of the scattering PF.
By comparing the XPS spectrum of the unused Pd nanocatalyst (see Figure S6b in the Supporting Information) with that of the used catalyst, it is obvious that there is a substantial increase of the component that belongs to PdO/Pd(OH 2 (i.e., at 336.3 eV) in the latter spectrum.
Remarkably, however, we also find that, at low viscosities (μ ≪10 mPa·s), human spermatozoa exhibit a substantial shear-induced transverse velocity component that becomes suppressed at very high viscosities.
