Robust stability and surface error assessment in interrupted turning under spindle speed variation

Abstract Predicting stability in turning becomes especially difficult when the process combines interrupted cutting with spindle-speed variation (SSV). The resulting time-dependent delays and discontinuous dynamics call for advanced numerical tools beyond conventional chatter ana...

Complex effects of sex reversal on reproductive success in wild frogs

Sex reversal, when the environment overrides genotypic sex determination, may hasten or delay climate-driven extinction in ectothermic animals, depending on sex-reversed individuals’ reproductive ability and offspring viability. Empirically, next to nothing is known about these t...
