They may be relatively more prevalent in some migrant cohorts reflecting uneven influences of behavioral, environmental, genetic, biological,and socioeconomic determinants of health.
On a large scale, the distribution of gravitational forces on the earth is uneven and influences the shape and movement of tectonic plates as well as influencing geomorphic processes such as orogeny and erosion.
We finally compared allele frequencies between Spanish to illustrate the potential effects of including samples with uneven African influences in population-based association studies.
Although the African influences estimated might be biased due to marker ascertainment, these results confirm that Northwest African genetic footprints are recognizable nowadays in the Spanish populations, particularly in Canary Islanders, and that the uneven African influences existing in these populations might increase the risk for false positives in association studies.
It can be known from the two figures that the distribution of node influence is uneven, and the nodes with bigger value are more likely having higher influence.
Experimental results show that this embedded control system structure can improve the mobile platform moving path accuracy and reduce the influence of uneven surface or wheel idle spinning.
However, the method proposed in this paper uses the relative characteristic of the pixel in local sub-regions to reduce the influence of uneven light and non-local spatial information to avoid noise interference.
As mentioned in Section 2.1, the wave transformation in Wei's method can reduce the bad influence of uneven light on the image segmentation by obtaining the local characteristic of each pixel.
In this section, we give a brief introduction to the wave transformation model proposed by Wei et al. [36], which is used to reduce the influence of uneven light on the segmentation of images.
Theorem 2 indicates that the wave transformation of an image using the fuzzy membership function (S-function) can reduce the light intensity difference between neighborhood sub-regions, thus markedly decreasing the influence of uneven light on the image segmentation.
Experiments on several test images show that the proposed method has excellent capability of decreasing the influence of uneven illumination on images and noise injection and behaves more robustly than several classical global and local thresholding methods.
