We first put forward a perceptual quality oriented motion estimation algorithm, which is conducted with a spatial-temporal just noticeable distortion (JND) model.
Several experimental systems show a drift: a slow oriented motion of the sample versus the imaging frame, which is caused by various factors of the experimenting apparatus.
For speed analysis, from each single-fiber preparation, 20 actin filaments that were moving at constant speed in an oriented motion were selected.
This is despite the fact that there exist only vertically and horizontally oriented local motion detectors.
There has been recent interest in the possibility that plant roots can show oriented collective motion, or swarming behavior.
Furthermore, the possibility has been raised of the operation of a "swarm intelligence",, or "group cognition", by means of which roots, through their oriented collective motion (via directional growth), optimize interaction with their environment.
In addition, among the subset of spc105 sisters that managed to bi-orient, motion on the spindle was different from that observed in wild-type cells: a particularly dramatic reduction in away-from-the-pole velocity was observed (4.50±0.12 mm/min in wild-type at 37°C versus 3.90±0.15 mm/min in spc105-4 at 37°C).
To further explore wide-field response properties, we varied the orientation of a full-field grating, demonstrating that this cell is strongly tuned to front-to-back motion oriented along the horizontal body axis and, like other wide-field Drosophila LPTCs [ 11, 23], exhibits a 1 Hz temporal frequency optimum.
Whenever the monsoon trough on the eastern side of the summertime Asian monsoon is in its normal orientation (oriented east-southeast to west-northwest), tropical cyclones along its periphery will move with a westward motion.
Then, in 1958, came an important extra-musical development, the hula hoop, and, in the early sixties, the Twist, cutting across generational lines and setting the country, from nursery to geriatrics ward, into agitated, rhythm-oriented motion.
In the 1970s Brown became "the Godfather of Soul," and his hit songs stimulated several dance crazes and were featured on the sound tracks of a number of "blaxploitation" films (sensational, low-budget, action-oriented motion pictures with African American protagonists).
