We developed a new theory-based azimuthal phase retardation microscope to visualize distributions of actin filaments in biological cells without having them with exogenous dyes, fluorescence labels, or stains. The azimuthal phase retardation microscope visualizes distributions of actin filaments by measuring the intensity variations of each pixel of a charge coupled device camera while rotating...

Residual stresses induced by laser shock peening in Ti-17 titanium specimens were experimentally and numerically investigated to identify the mechanisms generation conditions of retardation fatigue crack propagation (FCP). The was observed with life prolonged 150%. A multi-step simulation strategy for prediction is applied, which successfully predicts FCP behavior. fractographic observations nu...
