The phrase "a main function in" is correct and usable in written English.
It can be used when describing the primary role or purpose of something within a specific context or system.
Example: "In the ecosystem, a main function in maintaining balance is played by predators."
Alternatives: "a key role in" or "a primary function in".
The code after the main check is thus the same sort of code you would put in a main function in Java.
The template provides language-specific boilerplate, such as basic includes and a main function in C++, and tells reple where to insert different kinds of REPL lines to build a program.
Fourteen highly interconnected proteins are included in the region with a main function in transport (Fig. 4).
This resulted in a list of 58 genes, including several known PPARα target genes (ADFP, PDK4, SLC25A20), with a main function in fatty acid β-oxidation.
DNA methylation is the main epigenetic feature of DNA with a main function in gene transcriptional regulation as well as preservation of genome stability, and a wide variety of malignancies are characterized by aberrancies in DNA methylation [ 4, 5].
This, together with a finding that PSII membranes with PsbO2 have higher GTPase activity than PSII membranes with PsbO1 [ 21], led to a conclusion, that PsbO1 has a main function in the stabilisation of Mn4CaO5 cluster and the facilitation of the water oxidation reaction, whereas PsbO2 regulates the turnover of D1 subunit [ 19, 21, 23].
Rather than having a main function as in Java, the __name__ == '__main__' check is used to delimit expressions which are executed when the file is called as a script from the command line.
This is in line with the observation that dominant active variants of CCaMK were able to restore nodulation and infection in symrk mutant backgrounds, indicating that a main function of SYMRK in symbiosis is the activation of CCaMK (Hayashi et al., 2010; Madsen et al., 2010).
Clarification of meaning through re-iteration of candidates' responses or asking for further elaboration on short "yes" or "no" answers became a main function of the interviewer in the semi-structured interview process.
Growth of yeast mutants deficient in the sucrose non-fermenting 1 (serine-threonineeonine protein kinase that is related to the mammalian AMP-activated protein kinase was severely inhibited by NaCl indicating a main function of the kinase in regulating adaptative mechanisms to salt stress [ 1, 2].
We found that most of the proteins in a cluster have the same functions that are assigned as a main function for the cluster as shown in Figure 4.
