A comparative study (Sun et al., eLife, 2019) showed that the abundance of proteins at sites of endocytosis in fission and budding yeast is more similar in the two species than previously thought, yet membrane invaginations in fission yeast elongate two-fold faster and are nearly twice as long as in budding yeast. Here we use a three-dimensional model of a motile endocytic invagination (Nickaeen et al., MBoC, 2019) to investigate factors affecting elongation of the invaginations. We found that differences in turgor pressure in the two yeast species can largely explain the paradoxical differences observed experimentally in endocytic motility.

Lapping Machine

The V-groove angle of the machine is considered as one of important factors affecting the processing and the ball’s precision. To study its effect, the three-dimensional model of RDP lapping machine is built and a series of simulations at different V-groove angles are carried out, using the software ADAMS based on the RDP principle. The influence of three parameters including spin angle, spin angular velocity and revolution angular velocity are discussed by observing and analyzing the simulation results. It is concluded that some optimized V-groove angles can improve the sphericity of ball; some ones can induce the balls to move back and roll during some periods of the processing.
