Why do I yawn when I’m bored? Karen D. Sullivan, Ph.D., board-certified neuropsychologist and creator of I Care For Your Brain calls boredom-induced yawning the “biggest myth” associated ...

In 1508, Erasmus wrote, "One man's yawning makes another yawn", [39] and the French proverbialized the idea to "Un bon bâilleur en fait bâiller sept" ('One good gaper makes seven others gape').

The passive yaw systems utilize the wind force in order to adjust the orientation of the wind turbine rotor into the wind. In their simplest form these system comprise a simple roller bearing connection between the tower and the nacelle and a tail fin mounted on the nacelle and designed in such a way that it turns the wind turbine rotor into ...
A yaw damper (sometimes referred to as a stability augmentation system [1]) is a system used to reduce (or damp) the undesirable tendencies of an aircraft to oscillate in a repetitive rolling and yawing motion, a phenomenon known as the Dutch roll.
Sample hypnogram showing one sleep cycle (the first of the night) from NREM through REM. The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and ...
