Self-organizing dynamics of human erythrocytes under shear stress

The characterization of the erythrocytes' viscoelastic properties is studied from the perspective of bounded correlated random walk (Brownian motion), based on the assumption that diffractometric data involves both deterministic and stochastic components. The photometric readings are obtained b...
