The phrase "a minimal density of" is correct and usable in written English.
It can be used in contexts where you are discussing the amount or concentration of something, often in scientific or technical writing.
Example: "The experiment required a minimal density of the solution to ensure accurate results."
Alternatives: "a low concentration of" or "a slight density of".
This may explain why a minimal density of domestic ducks is required for persistence, but that their abundance does not proportionally relate to HPAI H5N1 risk.
These results were similar to those found in the heterocellular strands where spontaneous impulse initiation was induced with a minimal density of MFBs corresponding to ~−66 mV.
Assemblies were automatically detected by fitting an ellipse to the spatial distribution of response-modulated cells and were defined as unilateral clusters containing a minimum of six cells at a minimal density of 533 μm/cell (Experimental Procedures).
Although a similar effect is observed with the ABI3730 sequencer used here, the mutation-density calculations are based on the actual numbers obtained in the assays and therefore represent an estimation of the minimal density.
Honeycomb structures are the most widely used sandwich structures as it provides material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties.
There was only a minimal effect of stand density on breast height outerwood density, and a weak negative relationship between wood density and tree diameter within a stand.
These results indicate that inosine-mediated germination of B. cereus spores requires a minimal spore density.
It appears that trace amounts of pigments were only synthesized during the stationary phase thereby inducing a minimal increase of cell density (Figure 5B).
The issue of setting a minimal percentage for the density of a projection to be functionally relevant is however far from being trivial.
C. elegans was grown axenically in a chemically defined nutrient medium before being transferred to minimal buffer containing a standardized density of bacteria in multiwell plates.
C. elegans strain N2 was grown axenically in CeHR, washed, and transferred to minimal buffer containing a standardized density of bacteria in multiwell plates.
