OPTIMIZATION OF FAST TOOL SERVO DIAMOND TURNING FOR ENHANCING GEOMETRICAL ACCURACY AND SURFACE QUALITY OF FREEFORM OPTICS

Optimization of fast tool servo diamond turning for enhancing geometrical accuracy and surface quality of freeform optics

Fast tool servo (FTS) in ultra-precision diamond turning is an efficient technique for high-precision fabrication of freeform optics.However, the currently adopted constant scheme for control point sampling takes no account of the shape variation of the desired surface, which might lose some micro features and result in low form accuracy and non-un

An inflammation-related gene landscape predicts prognosis and response to immunotherapy in virus-associated hepatocellular carcinoma

BackgroundDue to the viral infection, chronic inflammation significantly increases the likelihood of hepatocellular carcinoma (HCC) development.Nevertheless, an inflammation-based signature aimed to predict the prognosis and therapeutic effect in virus-related HCC has rarely been established.MethodBased on the integrated analysis, inflammation-asso
