“…This paper focuses on fractal operators and fractional dynamics in biomaterials, biological structures and motions. In recent years, we have studied the following problems in biomechanics and biophysics: the first one is the constitutive response of muscle and ligament fibers [1]; the second one is the electrical signal transduction within nerve fibers [2], and the third one is the blood flow in arterial vessels [3]. Ultimately, it was astonishing to find that the three types of problems show surprising commonality, i.e., their basic laws can all be inscribed by fractal operators, and their mechanics are all 1/2-order fractional dynamics.…”
