"undergo fluctuations" is correct and usable in written English.
You would use it when talking about changes that occur in the size, amount, or value of something over a period of time. Example: The prices of oil have constantly undergone fluctuations lately.
From molecular modeling, we identify their median position and estimate that they undergo fluctuations of at least 30 Å.
These magnetic nanomaterials in the presence of an alternating current or magnetic field undergo fluctuations in their magnetic properties, resulting in variation in heat energy.
Clusters of water molecules in an ice-like configuration formed on heterogeneous nuclei are unstable (easily decay) and undergo fluctuations in size.
Since cellular metabolic demands undergo fluctuations depending on systemic physiological conditions, ER uses its unfolded protein response (UPR) machinery to fine tune its protein synthesis, folding, and secretion accordingly [ 87].
These included the front helices F and H, which have previously been implicated in NTD dynamics; they exhibit structural heterogeneity (Sukumaran et al., 2011) and undergo fluctuations when measured at a single-molecule level (Jensen et al., 2011) and in molecular dynamics simulations (Dutta et al., 2012).
C2-genes are associated with nucleosomes that undergo fluctuations of their modification level in α, while completely losing modification in Ω. Accordingly histone modification and transcriptional states of C2-genes are much more heterogeneous in cells within α compared to cells within Ω (Fig. 2B).
Each cell is about one bubble column diameter high and undergoes fluctuations in position and circulation velocity.
The cortex, immediately internal to the tunica albuginea, contains future eggs and, at one time or another, eggs in ovarian follicles (i.e., developing eggs); it undergoes fluctuations in size and appearance that correlate with stages of the reproductive cycle.
After undergoing fluctuations in intensity, Lester reached peak winds of 115 mph, a Category 3 hurricane on the Saffir-Simpson Hurricane Scale.
The larger variance at pixel k is due to a few bright particles undergoing number fluctuations while the smaller variance at pixel j is due to many dim particles undergoing fluctuations at that pixel.
The species and strain composition of the microbiota are generally maintained over the following years, while undergoing fluctuations according to the environmental factors mentioned above.
