The phrase "a very small frequency" is correct and usable in written English.
It can be used when discussing occurrences or events that happen infrequently or at a low rate.
Example: "The experiment showed that the phenomenon occurred at a very small frequency, making it difficult to observe."
Alternatives: "a minimal frequency" or "a low frequency".
The frequency of the output sine wave is set by a 32 bit control parameter, yielding a frequency resolution of 0.09 Hz which allows for very small frequency variations compared to the output frequency of 80 MHz.
Thus, it is interesting to study the performance of this method for two different scenarios: forced oscillations with very small frequency (i.e. 0.13) imposed on a generator and applicability of method on a large power system.
On the other hand, a substantial number of subnetworks with large frequency in prokaryote have very small frequency in eukaryote.
It should be noted, however, that the absence of serious bleeding could be a chance finding because this study was underpowered to detect events occurring with very small frequency.
This is not surprising considering that much of the DNA is present at very small frequencies, and a lot of effort would be spent trying to catch most of the rare bins.
We note that, at very small frequencies, changes in an allele frequency are dominated by genetic drift, with selection becoming the primary driver of evolution at a threshold frequency of 1/ Nσ (Rouzine et al. 2001).
Since the PMI give more weight to words with very small frequencies, we considered only n-grams that appear in at least 1% of men's or women's biography overviews.
A major problem in the assessment of gene associations at multiple loci results from limited sample sizes in relation to the very small frequencies expected for multilocus genotypes.
The resulting conditional fixation probability of the target mutation is Because the interfering mutation is deleterious, its probability distribution Q(x′; σ) is dominated by very small frequencies x′ ≪ 1.
