The variance of the motion signal comes from the square of a quadratic signal, and thus the noise statistics of the HRC depend on the fourth-order statistics of the image ensemble (Appendix 2).
Images were sampled from the International Affective Pictures database [ 14] and included disgusting, threatening, pleasant, and neutral images (see Appendix S1 available online).
In order to get more uniform distribution of PS spheres, the ICP etching is used to adjust the morphology (the scanning electron microscopy images are Appendix 1).
In the present study, we describe the continued development of an automated ROI technique custom-tailored for FDG and PIB-PET images (see Appendix for technical details).
Age, gender, handedness, and total intracranial volume (the brain volumes had been demodulated during the processing of the T1-weighted images, Supplementary Appendix A) were included as covariates.
The reason for this is that natural images are correlated (Appendix figure 1), and the accuracy of the HRC over a general image ensemble depends on the ensemble's spatial correlation structure (Appendix 2).
Finally, staining inconsistencies resulting in colour variations (such as apparent in the images selected for Appendix Figure 1), may also contribute to undefined pixels.

Implementing an image processing workflow (Appendix S7) includes advance planning for information flow, including provision for temporary and longer-term image storage (i.e., archiving strategy), specifications for downstream images, and plans for how and where images will be hosted online.
RDSR contains detailed log information of every X-ray event, including radiation time, air kerma (AK), dose area product (DAP) and number of images acquired (see Appendix 1).
