1.   Apart from random fluctuations, the deleterious effect of too short and too long spacing is seen for each order birth.

2.   But Blumstein and some other experts tempered their enthusiasm, noting that a slower growth rate in one year could be a random fluctuation.

3.   But the German physicists are wary of claiming too much, saying that they may only be detecting a random fluctuation.

4.   In some graphs, even the tiny squiggles that should arise from purely random fluctuations matched exactly.

5.   The noise in question mostly involves random fluctuations in the flow of particles and electrical current in microscopic systems like cell membranes and advanced circuitry.
