The phrase "a very low fraction" is correct and usable in written English.
It can be used when discussing a small part or percentage of a whole in various contexts, such as statistics or research findings.
Example: "In the study, a very low fraction of participants reported experiencing side effects from the medication."
Alternatives: "a tiny percentage" or "a minimal portion".
As-prepared rGO/F-C60 hybrids were subsequently integrated to the conductive polymer, poly (3,4-ethylenedioxythiophene):poly styrenesulfonate) (PEDOT PSS), at a very low fraction (below the percolation threshold).
This work demonstrates how a very low fraction of graphene greatly enhances the usage efficiency of carbon-based conductive additive in LiCoO2-based lithium ion batteries (LIB) and develops a strategy using binary conductive additive to have a high performance battery, especially with excellent rate performance.
In the system nc-TiN1−x/a-TiB2 with a minor fraction of the a-BN phase superhard coatings with a very low fraction of microparticles and resultant low surface roughness of Rm≈0.15 μm were successfully prepared and those are intended for testing under a variety of cutting conditions.
It might be expected that only few locations on an asteroid would statistically experience large above-the-average temperatures and, therefore, depending on the regolith mixing rate, only a very low fraction of the regolith grains would record an unusual temperature history.
Because only a very low fraction of the mouse genome sequence is likely to encode miRNA, it is safe to assume that most negative training examples are not miRNAs.
In contrast, there is a very low fraction of OMIDIs (0.26%, 4/1526) and nonsense mutations (0.13%, 2/1526) in EGFR singlets, consistent with a strong selection for mutations that alter, rather than delete, function.
Using this protocol and reference materials, we demonstrated the applications in accurate variant calling at very low fraction over a large region and in targeted RNA quantification.
Suitability of a particular mixing equipment for liquid dispersion is usually studied in systems with very low fraction of the dispersed phase.
Experimental results indicate that incorporation of very low fraction of graphene oxide (0.01%) can effectively hinder the ingress of chloride ions.
And 2010 is so far at very low fraction of Yea votes by Republicans (49%), beat only by 1993 (43%).
Indeed, as opposed to the very low fraction of CD34+ cells in the PBMC on day 0 (Figs.
