A somewhat similar system is observed in the propagation of action potentials in neurons, in which a short refractory period prevents backward signal propagation.
An easier way in figuring out due dates is to take the first day of your last period, count backward 3 months, add 7 days, and add an entire year.
"Georgian" came to be a pejorative term, used in a sense not intended by its progenitors: rooted in its period and looking backward rather than forward.
Inverse or backward period doubling cascades and sudden transition to chaos are observed.
Obviously, the search procedure for the optimal battery operation α 1, α 2, …, α N is the dynamic programming which starts with the last period and proceeds backward in time [15]; thus, we can obtain the optimal battery operation policy set (left { {mu _{1}^left ({{B_{0}}} right),~mu _{2}^left ({{B_{1}}} right), ~ldots,~mu _{N}^left ({{B_{N - 1}}} right)} right }).
In contrast, after the time period at which backward masking has an interrupting influence on the perceptual process (around 100 ms; Scheerer, 1973; Scheerer & Bongartz, 1973), only visual working memory capacity increased linearly with longer SOAs [ F 1, 15) = 8.222, p <.015, ηp =.354].
Forward and backward flow alternated with a period of 12 s (=trial duration) such that both occurred within each trial.
The maximum (backward) observation period was 3650 days.
She wonders what it was that made time stop & then go backward during that short period of her life.
During these periods time literally runs backward, and it's not long before he admits that he's from the future -- Dubuque, to be exact, and the year 2470.
