Then, various co-occurrence quantities including entropy, energy, contrast, homogeneity and correlation can be evaluated from the co-occurrence matrix to produce our texture features.
Therefore, we chose different periodontal sites as targets to explore the occurrence and quantity of A.actinomycetemcomitans and its CDT encoding gene in Chinese subjects and different periodontal status.
Despite the abundance of these compounds and their ubiquitous presence in plants, occurrence and quantity of phenolic compounds can vary dramatically from species to species, and also within single species depending on environmental, developmental, or genetic factors.
In contrast with its rare natural occurrence, bulk quantities of technetium-99 are produced each year from spent nuclear fuel rods, which contain various fission products.
The inter-porosity flow now has a slim chance of occurrence, and the quantity of the flow is small.
Relationships between frequency of occurrence and between quantity of seed deposition (either in number of faeces or seeds per km), and plant abundance (density or cover) at the nine sampling sites were tested by the Spearman's rank correlation analyses.
Microalbuminuria, the occurrence of small quantities of albumin in the urine, increased in 10 children treated with amalgam and in 2 treated with composite fillings, but it did not correlate with the number of amalgam fillings or with increasing concentrations of mercury excreted in urine.
When gel electrophoresis was subsequently tried to validate the presence of V. parahaemolyticus in fresh cockle samples, the PCR analysis found V. parahaemolyticus in spiked (treated and untreated cockle samples) whereas unspiked (treated and untreated cockle samples) were devoid of V. parahaemolyticus occurrence, correlating with the quantity of colony as discussed previously.
This is far from a random occurrence given their limited quantity.
Distance to nearest uranium mineralization was obtained by calculating the Euclidean distance from spatially referenced locations of known mineral occurrences with a significant quantity of uranium.
