The phrase "a dramatically smaller number" is correct and usable in written English.
It can be used when comparing quantities to emphasize a significant reduction in size or amount.
Example: "After the new policy was implemented, we observed a dramatically smaller number of applicants for the program."
Alternatives: "a significantly reduced number" or "a considerably lower number".
"Within the next five years," said Mr. Sawyer of Deloitte Consulting, "you are going to see a dramatically smaller number of American insurance companies.
This approach removes outliers and zero-mean Gaussian noise simultaneously and effectively while preserving most of the important signal features of a true FRF with a dramatically smaller number of operations as compared with the traditional mean-averaging procedure.
Says Georgia Tech electrical and computer engineering professor, Justin Romberg, "What this camera is actually looking at is not pixel values, but pixels added together in all different ways and a dramatically smaller number of measurements than if you had it in a standard mode".
Clock mutant and Bmal1-KO mice were found to have a dramatically smaller number and volume of mitochondria in muscles with aberrant morphology.
The utility of MVA-based vaccines to prime immune responses against heterologous antigens appears to be limited due to unfavorable competition for immunodominance between the relatively large number of vector-specific gene products (177 [3]) and the dramatically smaller number of intended vaccine antigens [24].
Recently, several sophisticated pooling designs were suggested that can identify carriers of rare alleles in large cohorts with a significantly smaller number of pools, thus dramatically reducing the cost of such large-scale sequencing projects.
The number of unknowns necessary to achieve a given accuracy with this new basis is dramatically smaller than the number necessary with a standard method, and it is virtually independent of the wavenumber k.
As a consequence, the number of random measurements required in CS is often dramatically smaller than the number of samples required in the other existing Nyquist sampling methods, which thereby leads to a significantly reduced sampling rate and hence greatly alleviate the complicated high-rate analog-to-digital converter (ADC).
The advantage of screening molecular fragments rather than drug-sized molecules is that a dramatically larger portion of chemical structure space is explored with a smaller number of compounds.
A smaller number is a lower risk.
