Polarization contrast and motion detection
Journal of Comparative Physiology A, 2006Form and motion perception rely upon the visual system's capacity to segment the visual scene based upon local differences in luminance or wavelength. It is not clear if polarization contrast is a sufficient basis for motion detection. Here we show that crayfish optomotor responses elicited by the motion of images derived from spatiotemporal variations

Abstract Using the auto-regressive technique, we have analysed data of polar motion, Earth's rotation and excitation function of Earth's atmosphere and obtained their low frequency spectra. These spectra have some periods in common and this fact suggests that these periods are probably real.

“Polar”-functions for Brownian motion
Zeitschrift für Wahrscheinlichkeitstheorie und Verwandte Gebiete, 1982Let (Xt)t≧0 denote the 2-dimensional Brownian motion. It is well-known that iff∶R+ →R2 is a constant function, then $$P\{ \exists t > 0\,X_t + f(t) = 0\} = 0.$$
