The phrase "a minimum density of" is correct and usable in written English.
It can be used in contexts where you are specifying the least amount of density required for a particular substance or material.
Example: "The construction project requires a minimum density of 2.5 grams per cubic centimeter for the concrete used."
Alternatives: "a required density of" or "a threshold density of".
We estimated a minimum density of 0.13 hyandas/kmaximummaximum density of 0.52 hyaenas/km2.
A lattice collapse model, requiring a minimum density of point defects locally, also gives too weak an ion mass dependence if the input is directly taken from binary collision simulations.
Since the data maps were initialized with a minimum density of 10 g/m2 to account for movement between triangular elements that is not simulated in this model application, a difference between model output and the data value falling within 20 g/m2 was considered a "perfect" match.
Bands with a minimum density of 5% were detected in each lane and bands were matched using a match tolerance of 2%.
The modules were identified to have a minimum density of >0.05 and a degree of >6.
Calcified coronary artery areas were identified as those with a minimum density of 130 Hounsfeld units (HU) and a minimum area of three pixels (1.03 mm).
In each instance the GAAATT motif was significantly over-represented in the SID2 cluster and parameters that gave rise to the maximum statistical significance observed were chosen for the final analysis – a minimum density value of 0.75 and a CP threshold of 0.75.
On the basis of six clouded leopard track sets we estimated a rough minimum density of clouded leopards in our small study area and extrapolated our local results to the landscape level.
A set of genes is a recurrent heavy module if the set of genes meet a minimum density (heaviness) threshold in at least a minimum number of coexpression networks.
The generation of clusters was constrained by a threshold for the minimum density of connections within a cluster and a parameter controlling the periphery tracking of clusters such that sparsely connected nodes would be ejected from a cluster even if the average connection density passed the threshold.
McDonald & Fox (1999) used closely related ideas in one of the first attempts to estimate animal density from acoustic data, presenting an estimate of the minimum density of fin whales near the north of Oahu, Hawaii.
