The majority of the ORFs showed considerable variations in expression among the four conditions, although most of the genes were over-expressed.
Chaud's visual cues convey emotion in humorous shorthand: slight variations in expression, and cheeks that flush from pale pink to peony.
Assessment of seasonal variations in expression of brain neuropeptide mRNA is complicated by concurrent circadian variations.
This creates a pool of transfected cells that typically display large variations in expression level and other characteristics.
While tumour heterogeneity also explains individual variations in treatment response, a monitoring approach based only on a single marker is sensitive to variations in expression of that marker.
Existing approaches for face recognition mainly deal with issues such as variations in expression, lighting, pose, and aging, but none of them is free from noise.
It was shown in[17] that this strategy can alleviate to some extent the pixel-shifting problem caused by some face deformations like variations in expression.
It is based on the use of gradient information on Gabor-transformed images, demonstrating its effectiveness with images having variations in expression and illumination.
Secondly, the pixels of different images of the same person may vary widely due to variations in expression, pose, viewing angle, illumination, and age, while the pixels of different persons may not vary significantly [5 7].
The WMPCA methodology, proposed by us earlier, is based on the assumption that the rates of variation of the different regions of a face are different due to variations in expression and illumination.
In some pinniped species, there appear to be geographic differences in vocalizations, known as dialects, while certain species may even have individual variations in expression.
