Theory of x-ray photon correlation spectroscopy for multiscale flows

Physical Review Research
Complex multiscale flows associated with instabilities and turbulence are commonly induced under high-energy density (HED) conditions, but accurate measurement of their transport properties has been challenging.

Design of a Hybrid Split-Delay Line for Hard X-ray Free-Electron Lasers

Photonics, 2022
High repetition-rate X-ray free-electron lasers (XFELs) enable the study of fast dynamics on microsecond time scales. Split-delay lines (SDLs) further bring the time scale down to femtoseconds by splitting and delaying the XFEL pulses.

XPC beyond nucleotide excision repair and skin cancers

Mutation Research/Reviews in Mutation Research, 2019
Xeroderma pigmentosum group C (XPC) has been known as a DNA damage recognition factor of bulky adducts and as an initiator of global genome nucleotide excision repair (GG-NER). XP-C patients have been shown to have a predisposition to develop skin and certain internal cancers. Recent studies have shown that XPC presents several functional and molecular
