The phrase "a combination of functions" is correct and usable in written English.
It can be used when describing a situation where multiple functions or roles are being integrated or used together for a specific purpose.
Example: "The software offers a combination of functions that streamline project management and enhance team collaboration."
Alternatives: "a blend of functions" or "an amalgamation of functions".
Pre-2013 this was possible, buthislied on a combination of functions (FIND, LEFT, &, etc).
That is because management is neither a science nor a profession, neither a function nor a combination of functions.
Here, we show that some newly synthesized compounds may exert such a combination of functions.
Moreover, according to the nondimensionalization results in Appendix 2, we find that the calcium derivative, denoted by (f_{2}), can also be represented as a combination of functions with different relative sizes.
For this reason, many researchers have focused on the 'quality' of T-cell response, a combination of functions that T cells are able to carry out, instead of the frequency of T-cell populations or phenotype characterization [ 57].
It is highly unlikely that species-poor plantations, which may be optimal for above-ground biomass production, will outperform species diverse assemblages for a combination of functions, including overall carbon storage and control over water and nutrient flows.
In a line like "With mirth in funeral and with dirge in marriage," from "Hamlet," the decisive words are "and with," a combination of function words more often found in Shakespeare's known plays than in, say, Thomas Dekker's.
The specifications are realised through the use of a combination of function decomposition strategies, data refinement techniques, and off-the-shelf refinements based upon higher-order functions.
In conclusion, this study revealed that an oil reservoir microbial assemblage harbored novel metagenomic diversity and could be mined for thermostable cellulases and other CAZymes using a combination of function- and sequence-based methods, demonstrating the strength of hybrid screening approaches.
The outcome measure was based on a combination of function, alignment and need for further intervention: this is considered excellent if the patients were fully weight-bearing and pain-free on a mechanically aligned limb without need for further surgery; good if the patient required more surgery to achieve union; and poor if irreversible complications occurred.
In the study of higher-order Fourier analysis, this corresponds to approximating every function by a combination of structured functions plus a function of small Gowers norm; in graph theory it corresponds to Szemeredis regularity lemma; in cryptography it corresponds to approximating distributions dominated by a pseudorandom distribution by distributions of high min-entropy; and so on.
