Predict Blood Pressure by Photoplethysmogram with the Fluid-Structure Interaction Modeling

Communications in Computational Physics, 2022
Blood pressure (BP) has been identified as one of the main factors in cardiovascular disease and other related diseases. Then how to accurately and conveniently measure BP is important to monitor BP and to prevent hypertension.

Fractional powers of the Stokes operator with boundary conditions involving the pressure

Mathematische Nachrichten, 2019
Since the pioneer work of Leray [21] and Hopf [15], Stokes and Navier-Stokes problems have been often studied with Dirichlet boundary condition. Nevertheless, in the opinion of engineers and physicists such a condition is not always realistic in ...
