Sentence examples for processes drift from inspiring English sources

Rather it is that the model identifies the relationship between evolutionary processes (drift, selection, effective population size, rate of environmental change) and population persistence.

Analyses of genetic variation now involve nucleotide data, which can be used in a variety of statistical tests to discriminate between patterns of variation due to neutral processes (drift, population expansion, bottlenecks) and various types of selection (positive, purifying, balancing).

The dynamics by which mutations accumulate within populations are complex as the result of stochastic mutational processes, drift, natural selection, and competition between clones of different overall fitness (Gerrish and Lenski 1998; de Visser et al. 1999; Desai et al. 2007; Miller et al. 2011; Lang et al. 2013; Lee and Marx 2013).

Given time, populations separated by erosion gaps will diverge as a consequence of both adaptive divergence and neutral processes (drift), the latter being more important where the selective differentials between populations are low and/or population size is small with limited gene flow [ 21].

The use of process control resulted in the film composition being constant throughout the depth of the thin-film, as opposed to having a graded composition due to process drift.

Process drift or process improvement, introduced through automation of procedures or changes in reagents, equipment, operator, or platforms, may involve relatively subtle effects on microarray data.

Thus, activation patterns in distributed corticobasal ganglia circuits are largely consistent with the predicted responses from our computational model of competing decision dynamics on execution process drift rates.

We should point out that the inclusion of the exponential parameter in the execution process drift rate implements a similar process as a collapsing bound on the decision times (Ratcliff & Frank, 2012).

For both reactive and proactive tasks, we compared three possible influences of context on the execution process: drift rate modulation (F ), boundary shift modulation (G ), and onset delay modulation (H).

And as Mr Musharraf became distracted by a losing battle to retain power, the peace process drifted.Once resumed, the talks are likely to be dominated by how to combat terrorism, not solve Kashmir.

This includes extreme class distributions of Gaussian/non-Gaussian types and process drifts.
