If.. Figure 10 Upper row: gray level symmetry; Middle row: vertical edges symmetry; Lower row: horizontal edges symmetry.
This is important given the similar pattern of joint involvement and clustering by symmetry, row and ray among individuals with erosive osteoarthritis and those with increasing grades of non-erosive hand osteoarthritis.
The surface can be seen as many parallel rows of atoms; although, because of the triangular symmetry, those rows can be taken as running in any one of three directions--just like the rows of a Chinese checkerboard.
The proposed slope limiting strategy preserves the consistency of the underlying discrete problem and the structure of the stiffness matrix (symmetry, zero row and column sums).
It must be pointed here that for quantum dots grown on [001] substrate there are also two non-equivalent axes: [110] and [11 0], with anisotropy clearly visible on shear strain distribution in Figure 3 lower row), suggesting low C2v symmetry of this quantum dot system.
The angles between rows indicate rotational symmetries of the atomic positions.
Symmetry is defined here as the sum of the symmetry of each row in the resulting image.
Trends in the patterning of joint involvement were strongest by symmetry followed by row and then ray for erosive osteoarthritis and increasing grades of radiographic osteoarthritis, although in erosive joints statistically significant odds were only seen for symmetrical patterning (table 2).
Several studies provided clear evidence for a polyarticular subset of hand OA in women [ 28, 35- 37], with three major determinants of the pattern of polyarticular involvement being symmetry, clustering by row, and clustering by ray (in descending order of importance).
For quantitative data, FALCON uses the same methods as for binary interactions, but also utilises weight data to break symmetry when two rows (columns) have the same degree; in this case, the row (column) which has greater values for most overlapping elements is ranked highest.
