Surface characterization in fabrication environments using angle resolved light scattering: From roughness and defect analysis to in-situ coating inspection [PDF]

open access: yesEPJ Web of Conferences
The performance of an optical component or surface might quicky be limited by light scattering induced by the surface and coating roughness, as well as imperfections and contaminations. On the other hand, the scattered light contains valuable information

RAD50 missense variants differentially affect the DNA damage response and mitotic progression

open access: yesFEBS Letters, EarlyView.
RAD50 incorporates into the MRN complex and initiates the DNA damage response. Furthermore, RAD50 promotes mitotic progression. RAD50 missense variants capable of forming an MRN complex supported the DNA damage response and mitotic features to different extents in complementation experiments, indicating these functions are separable and might impact ...
