Grey-level size zone matrix.
Zone percentage is calculated from a Grey Level Size Zone matrix (GLSZM) by assessing the fraction of recorded zones compared to the maximum number of possible zones.
[17] were able to predict the radiological response using only baseline FDG-PET with a sensitivity of 92% only when textural features such as local homogeneity, entropy and size zone were calculated.
In this model, evolutionary growth of structures is classified into different-size zones 1 3, 5 20, 20 40, 50 200 and 200 400 nm.
It is ultimately up to policy makers and stakeholders to determine the acceptable level of risk, involving a cost benefit analysis of the potential outcomes, but quantifying the risk of spread from different sized zones is a prerequisite for this.
For that purpose three images per tumor were taken, each superimposed by a 15 × 12 square grid that allowed to subdivide the entire image into five equal-size zones (each with 3 × 12 square area): zones 5 + 4 (= tumor core), 3 (tumor edge), 2 (near migration) and 1 (far migration).
In the new figure, enlargements from two similarly sized zones of clathrin in either the HeLa SS6 or HeLa clone #64/1.E cells are presented.
For instance, once small (in comparison to the process zone size) weak/strong zones are present, a substantial decrease in the fracture energy is recorded.
Micro-shear band zone size, debonding zone size, and the areal density of steps also followed increases in the volume fraction.
Interestingly, features derived from all three gray-level matrices appear to be influenced by the metastatic growth, which could be an indication for the destruction of liver acini (alteration of co-occurrence and size-zones) or the tumor neovascularization (run-lengths of vessels).
