They were also a constant landmark for generations of clubbers and cinephiles on their way to parties and raves in the deserted goods yards near York Way or the all-nighters at the nearby Scala cinema.
The kinetic model in Figure 3 (modified units) generates the family of DED1 curves shown with zero-order rate constants for generation from k = 0 to k = 0.016 ([Cn] = > [Cx]).
This structure was kept constant for 1000 generations.
The simulated population started with 1000 animals with an equal sex ratio, and this structure was kept constant for 1000 generations.
At time zero, the population size changed instantly to N2 and then remained constant for t generations, until the population was sampled.
ML analyses used the automated stopping criterion, terminating a search when the likelihood score remained constant for 20,000 consecutive generations.
One example comes from glucose limitation experiments in chemostats, where a population's environment is held constant for hundreds of generations.
A random starting tree and the automated stopping criterion (stop when the ln score remained constant for 20,000 consecutive generations) were used.
Three independent maximum likelihood (ML) runs were conducted in GARLI (Zwickl 2006), using the automated stopping criterion, and terminating the search when the -ln score remained constant for 20,000 consecutive generations.
First, and apparently quite robust, is that the basic mutational properties of the N2 strain of C. elegans, under these particular conditions, on average, remain very constant for hundreds of generations of MA.
