The curvature at a point P of a curve is defined asx=| (dφ )(ds)|where φ is the angle of inclination of the tangent line at P, as shown in the figure. Thus the curvature is the absolute value of the rate of change of φ with respect to arc length. It can be regarded as...

Cells interact with the curved surfaces of many organs and, at a lower scale, with the rounded features of the extracellular matrix, which inherently links geometric form and biological function. The curvature of the extracellular matrix influences vital cellular processes by defining physical boundary...
