Estimating temperature distribution and heat quantity of spindle shaft for machining centers
Journal of Advanced Mechanical Design, Systems, and ManufacturingThe thermal issue of spindles for machining centers is still fundamentally unresolved. Thermal problems due to increased temperature of the spindle shaft lead to thermal displacement of the tool axis and an increase in friction torque, consequently ...

Finding novel vulnerabilities of hypomorphic BRCA1 alleles
Molecular Oncology, EarlyView.Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have
