The analysis of the UM3 shape variation provided a balanced contribution on the first two principal axes (PC1 = 27.0% of total variance and PC2 = 22.7%).
To see why, consider the following heuristic, which is based on an extension of the standard theory of fitness variation maintained at a balance between recurrent mutation and purifying selection (Mukai et al. 1974; Charlesworth 1987).
This indicates that multiple evolutionary forces are apparent, with sequence variation determined by a balance of conservative and innovative pressures.
We refer to local adaptation clines as monogenic clinal variation patterns maintained by a balance between the divergent effects of selection and the homogenizing effects of migration.
The bowling attack, with the left-arm angle of Ryan Sidebottom and the combination of Graeme Swann's off-spin with Yardy's slow left-arm, had a balance and variation that was obviously at odds with some of the more staid sides.
The confidence with which one can make a decision, however, depends on creating a balance between variation and expectation (Watson, 2005).
Current models of simple sequence repeat evolution suggest that the abundance and variation at SSRs results from a balance of two opposing mutational forces.
In fact, there exists a balance between the variations in these two regions.
When modeling temporal phenomena, there is a balance between removing random variation, i.e. noise, while still retaining signals with potential clinical significance.
It is a variation of an ampere balance in that it employs an extra calibration step that nulls the effect of geometry.
