Summary: This work presents an approach to make complex photo-finishing pipelines differentiable, allowing legacy algorithms to be trained with first-order optimization methods. By combining tailored network proxy models of individual processing steps, a non-differentiable reference image finishing pipeline can be more faithfully modeled and applied in various applications.

Summary: The study investigates the effect of magnetorheological fluid assisted magnetic abrasive finishing (MRAF) process on the surface topography of high strength biomedical grade I3-phase Ti-Nb-Ta-Zr alloy. The study analyzed the impact of MRAF processing parameters on surface characteristics and found that the I3-TNTZ alloy exhibited excellent biomechanical properties. The optimal conditions for achieving the lowest surface roughness and highest material removal rate were identified for the raster path finishing strategy.

Summary: The measurement accuracy of vibratory surface finishing forces is affected by the wiring of the force sensor. A triaxial wireless force sensor is developed to solve this problem and measure the forces between media and workpiece surfaces in vibratory surface finishing. Experimental results show that normal impacts between the media and workpiece are dominant, and the mean forces on the front surface of the workpiece are larger than on the side and rear surfaces. The mass and shape of media significantly affect the forces, which in turn affect the surface roughness and hardness of the workpiece.

Summary: The differential ionization probability of chiral molecules in the strong-field regime was found to vary with the helicity of the incident light, with an increase in photoion circular dichroism signal strength by 2 orders of magnitude being observed through molecular orientation resolution. This result was demonstrated through the analysis of fourfold ionization of CHBrClF and different dissociation channels of singly ionized methyloxirane.
