The phrase "a fraction of different" is not correct in standard written English.
It seems to be an attempt to express a small part or degree of difference, but it lacks clarity and proper structure.
Example: "There is only a fraction of difference between the two proposals, making it hard to choose."
Alternatives: "a small degree of difference" or "a slight variation".
A given entropy value can be related to a high fraction of different amino acids at one site and limited variability at other amino acid sites, or to limited variability at a large number of amino acid sites.
Diseases in different clusters thus show a larger fraction of different miRNA dysfunctions (P = 5.97×10−13, Fisher's Exact Test).
They represent just a fraction of the 74 different artists and 150 printers who've produced well over 2,000 editions in the 50 years since Gemini G.E.L. first opened.
Comparison of the relative nucleotide content of the three genomic regions indicates a homogenous distribution with no single nucleotide being more than a fraction of a percent different across these regions.
We quantified the penetrance of a given phenotype as the fraction of different single-gene expression perturbations in a circuit's initial state that produce this phenotype.
Nylon-6 in formic acid solvent was allowed to degrade by simply allowing it to stand for a long time, and nanofibrous mats were fabricated by taking a fraction of this solution at different time intervals via electrospinning under the same electrospinning conditions.
The work by Stamatiou et al. has reported the facilitating effect of ZnO diluents on the Zn oxidation with CO2 as a function of the mass fraction of different ZnO sources that, however, had similar specific surface areas and mean particle sizes.
It is also experimentally easier to understand the impact of stochasticity on the steady-state behavior (by measuring the fraction of different cell phenotypes in an experiment).
There are caveats to measuring public-funded science purely as a fraction of GDP – every economy is different, and it's tempting to oversimplify.
The most direct instrument is compensation to the municipalities of a fraction of the benefit payments to different categories of unemployed or sick-listed.
