For the basal cancellous bone, the interradicular area between the first and second premolars (4-5) showed the highest density values and the area between the central and lateral incisors (1-2) showed the least (Table 2).
In this implementation, we selected the jet colourmap,e where blue represents the lowest and dark red-brown the highest density values, respectively.
We evaluate the conditional robustness for the single value p23, p24, p35, p36 and p27 obtained fixing the lower L and upper U set with a parameter α=0.1, and setting them to the highest density values for the corresponding densities conditioned on set L, (see last line in Table 1).
Using a "maximum intensity projection" the software (ANALYZE 11.0, Biomedical Imaging Resource, Mayo Foundation, Rochester, USA) projected the most dense voxels onto the surface and assigned them colours, where the highest density values (>1200 Hounsfield units) were represented in black and lower values in red, yellow, green, and blue (in descending order) [ 25, 26].
Its high density value equally demonstrated its excellent performance.
The reason for using a "high" density value, = 80, is as follows.
Therefore, a data point will have a high density value if it has many neighboring data points.
Further comparative quantitative studies reveal that despite its high density value, there is little clustering in Alheim.
With a relatively high density value, we preserve a dense cluster structure (although some "sparse" red/green voxels around the current cluster boundary may be excluded in the DBC process).
The high degree value of the startup level of the Parisian ecosystem and the relatively high density value indicate vitality in this level, even in the absence of strong social cohesion that might be exhibited with greater connectivity across the small clusters in the startup level.
