Immediately after melt oscillation, Scorim can move the two pistons
back and forth in concert, creating compression and decompression effects in the cavity.
Each month we spray a light silicone lubricant on the locking handle and work the handle
back and Forth until it moves Freely.
Moreover, when volunteers hold their hands palm to palm, the vibrating device on either the right or left wrist tendon makes them perceive both hands as moving
back and forth. Primary motor cortex on the right side of the brain regulates left-side movements, and that on the left side controls right-side movements.
In A la Motte, 1993, time-lapse photography records a delicate white moth eating a hole into a sheet of black knitting; in Parade, 1993, a cadre of silkworms troop

back and forth, not side to side, to avoid damage.
One version forms the dynein arms, whose motion whips 9+2 cilia

Whenever the floor moves, the computer sends signals that drive the movable mass

"Imagine a marble in a bowl, rolling
back and forth," says Monroe.
To charge and discharge the battery lithium ions "rock"
back and forth between the battery's two electrodes, says Dominique Guyomard of the University of Nantes, France.
When they injected some noise by introducing fluctuations into the electronic signals controlling the laser, they found that the laser's light direction would switch
back and forth in time with an incoming, periodic signal normally too weak to influence the laser.
The switching
back and forth introduces a lot of systematic errors that reduce the accuracy.
