In the last PET frame, a centrally placed sphere-shaped VOI was defined on each sphere with the same diameter as the physical sphere.
One arrives at this lattice by starting from a layer of hexagonally placed spheres.
For this purpose we placed spheres of 4 mm radius on MNI coordinates associated with each system by Libby et al., (Libby et al., 2012) (see Table 1 for the selected coordinates).
Regions of interest (left NAcc, right NAcc and VTA) were selected based on the literature and were defined by placing spheres centered on Talairach Daemon coordinates.
In this respect, an RSA process (Evans 1993) is a kind of hard-core process where the pattern is constructed by placing spheres in 3-dimensional space iteratively and randomly, with their radii following a probability density function.
Consequently, the docking programme used in this study (DOCK 3.5 ) was biased to address this part of the binding site by only placing spheres for ligand matching close to the cluster of positively charged residues.
Full details of these voxels can be found in Tables 1 and 2. > -wrap-foot> > -wrap-foot> In order to plot activity at different regions for the relevant and irrelevant mean and variance, we placed a sphere of 5 mm radius on the peak voxel in each cluster identified as responding to either the relevant mean or relevant variance.
In 1946 the British and French governments placed their spheres of Togoland under United Nations (UN) trusteeship.
Taking the distance of the Sun as 1,266 Earth radii, he was forced to place the sphere of Venus above the sphere of the Sun; as a further refinement, he added the planet's diameters to the thickness of their spheres.
From the aEDT, the accessible covering radius transform (aCRT) is computed in the same way the CRT is obtained from the EDT; by visiting each point of the aEDT, placing a sphere of the prescribed radius there and taking the maximum over all such spheres covering a given voxel.
Thus, it is the muscle more involved in pushing the sphere towards the leftmost container, while it remains relaxed when the participant is asked to place the sphere into the rightmost container by exerting a finger adduction.
