The stimulus pattern consisted of a rotating polar checkerboard pattern (∼2.5 Hz visual modulation at 100% contrast).
By contrast, at high viscosity (Video 3), one can observe instances where the projected flagellum appears as an almost straight line, suggesting that the beat pattern approaches the shape of a rotating planar wave.
This pattern of motion generates a percept of a rotating cylinder with a compelling sensation of 3D depth (Treue et al., 1991) (Video 1).
A third convective style was motivated from observations of the patterns of convection in a rotating spherical container conducted by Aubert et al. (2001).
It consists of a rotating drum.
Every ten minutes, the pattern of light rotated 90° in a clockwise direction, for a total of 3 rotations over the course of the evaluation (with the lighting conditions at the end of the trial being the inverse of those at the beginning).
Because Testaverde played for the franchise when it was based in Cleveland, it was Harbaugh, in a sense, who started the pattern of rotating quarterbacks.
Planetary rotation rate is one of the major factors determining the circulation of the atmosphere and hence the pattern of clouds: slowly rotating planets create thick clouds that reflect more and so can be habitable much closer to their star.
A couple of these animated treatments are ready to roll: one has the new logo zooming backward and another shows a red background with a pattern of stripes that rotates as it recedes to form the new logo.
