The phrase "a certain module" is correct and usable in written English.
It can be used when referring to a specific module that is not named or specified, often in technical or academic contexts.
Example: "In our analysis, we focused on a certain module that significantly impacts the overall performance of the system."
Alternatives: "a specific module" or "a particular module".
It is represented by a decrease in the total water production beyond a number of stages or a certain module length.
We develop conditions on the roots of g under which a functor of cohomological induction maps a certain module of parabolic induction to another module of parabolic induction, extending a result due to Vogan.
Firstly, the MAPK network was conceptually divided into six subnetworks, each of which corresponds to a certain module and its potential regulators.
This hypothesis is further supported by the observation that proteins belonging to a certain module tend to be coexpressed [ 29] and coregulated [ 30].
For instance, if students report that problems in a certain module stimulated them to work hard, it does not necessarily mean that they actually worked hard.
Next, the analysis assesses whether particular group of samples (such as pN0 or pN+) preferentially over- or under-express a certain module of genes.
It is believed that the activation of MAPK cascade requires a scaffold protein that assembles the MAPKKK, MAPKK, and MAPK proteins together into a certain signaling module (75).
Algorithm (3) is convergent and the non-zero entries in solution x (determined in practice as entries that are greater than the cutoff, 0.1 is used in this study) define a certain subnetwork (module).
The goal of this step was to prevent easier module structures (small modules, low number of modules, and no overlap) of certain module definitions and datasets from disproportionally influencing the final score.
Certain module definitions, strict coregulation in particular, and datasets, E. coli, and synthetic data generate modules that are better co-expressed within the expression data, which could explain why module detection methods generally also perform better on these datasets and module definitions (Fig. 2c,d).
Thus, the local Zn2+ concentration may affect the degree of higher order structure within the PSD in a way that certain "modules" will be selectively enriched.
