A cell and its two neighbors form a neighborhood of 3 cells, so there are 2 3 = 8 possible patterns for a neighborhood. A rule consists of deciding, for each pattern, whether the cell will be a 1 or a 0 in the next generation. There are then 2 8 = 256 possible rules. [6]
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
The first row shows the reaction, which some authors label R and some leave blank. The second row, labeled I, has the initial conditions: the nominal concentration of acid is C a and it is initially undissociated, so the concentrations of A − and H + are zero. The third row, labeled C, specifies the change that occurs during the reaction.

Transformation into negation normal form can increase the size of a formula only linearly: the number of occurrences of atomic formulas remains the same, the total number of occurrences of and is unchanged, and the number of occurrences of in the normal form is bounded by the length of the original formula.

G 1 phase is particularly important in the cell cycle because it determines whether a cell commits to division or to leaving the cell cycle. [2] If a cell is signaled to remain undivided, instead of moving onto the S phase, it will leave the G 1 phase and move into a state of dormancy called the G 0 phase.
Steps of the cell cycle. The restriction point occurs between the G 1 and S phases of interphase.. The restriction point (R), also known as the Start or G 1 /S checkpoint, is a cell cycle checkpoint in the G 1 phase of the animal cell cycle at which the cell becomes "committed" to the cell cycle, and after which extracellular signals are no longer required to stimulate proliferation.
