The phrase "a cluster of variations" is correct and usable in written English.
It can be used to describe a group or collection of different forms or versions of something, often in contexts like research, art, or data analysis.
Example: "The study revealed a cluster of variations in the participants' responses, indicating diverse perspectives on the issue."
Alternatives: "a group of variations" or "a collection of variations".
At the end, a cluster of voices sang lush variations on "I believe in waking up together," and the Bowie guitar riff gently descended to a drone.
Finally, we note that the apparent functional redundancy detected here did not seem to reflect concerted up-regulation of any single pathway, since a cluster analysis of variation in protein abundance across gels showed that the SFPs that were associated with a given phenotype did not generally tend to cluster together (Additional file 1: Figure S2).
Indeed, we found a significant association with SBP variation for a cluster of intronic SNPs.
We deviate from the formulation of the earlier work and do not let the covariate effects, α, operate directly on the latent variable, X lat, which represents the coherent variation within a cluster of peaks.
Variations occurring in a cluster of genes that make up the major histocompatibility complex (MHC; also called human leukocyte antigen, or HLA, system), which regulates immune function, appear to have the most significant effect on risk.
Here, we discovered between the two rat lines differences other than the Aph-1b gene defect, including a remarkable cluster of genetic variations, two variants corresponding to topoisomerase II-based recombination hot spots and an epigenetic (DNA methylation) difference in cerebellum and (hypo thalamic but not hippocampal genomic DNA.
The results reveal the connection between the formation of a cluster and the variation of energy in fluidized beds.
A previous study reported familial clustering of variation over time in global DNA methylation using the LUMA assay (Bjornsson et al., 2008).
The best way to characterize these continental patterns (as discrete clusters of variation) is by examining them to a genomic scale, given that single locus could not necessarily capture the global genomic scenario.
