The multiplicative attenuation correction factor for the geometric mean quantitative method is the square root of the region without-to-with count ratio, raised to the power μ140/μ122 to convert from Co to 99mTc attenuation, where μ140 and μ122 are the mass attenuation coefficients for 99mTc and Co, respectively.
The quantitative geometric structures of molecules can also be obtained from the measured transitions in its microwave spectrum.
Recent literature on semantic mapping lacks effective and efficient approaches for grounding qualitative spatial relations through analysis of the quantitative geometric data of the mapped entities.
It accurately defines morphological variability in human tumours by quantitative geometric and topological analysis.
From our perspective, it is misleading to equate "spatial relationships" with the geometry of the environment; we would say there are quantitative (geometric) and qualitative (topological) relationships.
Quantitative geometric measurements of cartilage parameters, such as cartilage thickness and volume, have been suggested as sensitive image based biomarkers for detecting and monitoring cartilage degeneration in osteoarthritis [ 45].
This rather old and intriguing question had a substantial boost after the 70s within the framework of heterochrony (changes in rates or timing of development) and nowadays has the potential to make another major leap forward through the combination of approaches: molecular biology, developmental experimentation, comparative systematic studies, geometric morphometrics and quantitative genetics.
Six quantitative metrics, geometric and topologic, were analyzed, and their ability to classify different road network patterns were compared.
This approach – Freedom and Constraint Topology (FACT) – is unique in that it is based upon sets of geometric entities that contain quantitative information about a flexure system's characteristics.
The images that the microscopes deliver are "data planes" [2, 3] from which quantitative structural-geometric information is to be extracted (rather than to be interpreted visually in a more qualitative way).
