geometric) mean of the fitness landscape is degenerate, regions in which the fitness fluctuates around the mean value present a selective advantage over regions in which the fitness stays at the mean.
This gives DGENs a "funnel-like" shape with a gradually increasing number of genes after stage-1; H fluctuates around 0.5, as expected for an increasing sequence.
The sway force of the robotic fish fluctuates around 0 mN.
The period of circadian rhythms often fluctuates around 24 h due to the changes of environmental factors.
Still, in Japan the yen has become a sensitive issue as the currency fluctuates around a 15-year high.
Over time, the number of attendees, which appears to be a random (or chaotic) sequence, fluctuates around the threshold.
By contrast, the CD parameter tends toward two dimensions at first, then fluctuates around a large value and then rapidly decreases toward one dimension.
We find that titin fluctuates around a steady-state length after ~5 min under a 1 Hz triangular force cycles between 0 and 30 pN.
The stacking fault fluctuates around 35 Å in the subsonic regime, but subsequently declines with velocity to less than half the initial value in the second transonic regime.
Generally the slope fluctuates around a mean value but in certain cases (sites with low seasonal effect) abrupt slope changes are derived and the slope becomes strongly unstable.
Specifically, friction coefficient μ of in-situ Cf/Al2O3 reduces from 0.45 to 0.39 with time and fluctuates around 0.17 under dry and water lubrication respectively, while μ of Al2O3 is about 0.52 and varies around 0.35.
