Cross-sectional study
In medical research, social science, and biology, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study In economics, cross-sectional studies typically involve the use of cross-sectional regression, in order to sort out the existence and magnitude of causal wikipedia.org

Cross-Sectional Design. Cross-sectional designs help determine the prevalence of a disease, phenomena, or opinion in a population, as represented by a study sample.Prevalence is the proportion of people in a population (sample) who have an attribute or condition at a specific time point regardless of when the attribute or condition first developed (Wang & Cheng, 2020).

If a non-unit-speed has constant curvature and zero torsion, is it a circle necessarily? I've found an answer to the question I had here. But in that answer, we assume that the curve at hand has unit speed. In workin...
The shape of the trajectory does not depend on the speed, so it needn't be unit. (Think that tough you can drive at different speeds, the road remains unchanged. :) The curvature and torsion formulas are established by computing the curvilinear abscissa, which "normalizes the speed away".

Physiological cross-sectional area
In muscle physiology, physiological cross-sectional area (PCSA) is the area of the cross section of a muscle perpendicular to its fibers, generally at It is not the same as the anatomical cross-sectional area (ACSA), which is the area of the crossection of a muscle perpendicular to its longitudinal axis wikipedia.org

Characteristics of radius of blood vessel **Which properties do determine the radius of blood vessel?** I have these thoughts * distension, * elasticity, * contractility and * cross-sectional area of the w...
The radius of a blood vessel is entirely defined by only two parameters: 1.blood pressure 2.compliance of the vessel walls Of course, active contraction can decrease the vessel radius. Physically, this is a decrease in compliance, so the above relation always remains true.
