An Orientation Weight Algorithm for Five-Axis OMI System
DEStech Transactions on Engineering and Technology Research, 2019 The length of the inspection path and the number of probe orientations are two basic path planning goals. For the number of probe orientations, minimizing the number of probe orientations will cause the probe to swing too large when measuring some local measurement points.

Motion and Virtual Cutting Simulation System for a Five-Axis Virtual Machine Tool
International Journal of Automation and Smart Technology, 2011 Machine tools are an indispensable link in high-efficiency high-tech production. However, since five-axis machine tools are very costly and their use requires a high level of knowledge and expertise, a virtual machine tool must be used to simulate five-axis machine tool operation.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
