"It creates a positive wave in your day."

The closing valve causes a buildup of pressure that travels up the runner as a positive wave.

He wants to send positive waves.

The negative pressure (suction) of the blast wave follows immediately after the positive wave.

When the valve closes, it causes a pile up of gas giving rise to a strong positive wave that must travel up the runner.

The resulting recording is a series of vertex positive waves of which I through V are evaluated.

K complexes are phasic events (isolated occurrences) in which there is a sudden increase in negativity on the scalp, followed by a corresponding positive wave.

A shorter runner would flow earlier but also would die earlier while returning the positive waves much too quickly and those waves would be weaker.

The positive wave shoves outward from the point of detonation, followed by the trailing vacuum space "sucking back" towards the point of origin as the shock bubble collapses.

This causes a pile up of air, which becomes a positive wave reflected back up the runner and the red line shows that wave arriving at the runner entrance later.

At higher intensities the DP is followed by slow positive waves (Adrian's Deep Response) or by a prolonged negative wave lasting for more than 200 ms (Chang's second component).

The results, several Democrats said, were at least partly driven by the fact that Dr. Dean alone has been advertising heavily in New Hampshire over the past month and has been riding a positive wave of national publicity, including cover stories in Time and Newsweek.

At the right, the lower trace shows a negative wave that corresponds to a current sink caused by positive charges entering cells through postsynaptic glutamate receptors, while the upper trace shows a positive wave that is generated by the current that leaves the cell (at the cell body) to complete the circuit.
