The Boundary Value Problem of Focal Adhesions of Cells Is Not Inverse Problem

It is proved that the boundary value problem of focal adhesions of cells is not so-called inverse problem and proposes direct methods for the stress analysis on focal adhesions of cell locomotion. The problem needs not, like the former works, to reduce to inverse problem for solving. It is well-known that the inverse problem is ill-posed, and causes quite complicated and unstable problems. The direct formulations here are well-posed and very easy to realize and can exactly treat more complex focal adhesion problems of cells, in particular, for single focal adhesion problems the closed form analytic solutions are available, which can exactly explore the effect of configuration of focal adhesions.
