Radiation resistance of refractory high-entropy alloys

Response of refractory high-entropy alloys MoNbTaVW and HfNbTaTiZr to ultrafast radiation is modelled with the hybrid code XTANT-3, combining tight-binding molecular dynamics with the transport Monte Carlo and Boltzmann equation. A two-temperature state with elevated electronic temperature and a cold atomic lattice is studied.

Pelvic venous disorders in women: Diagnosis and management for gynecologists

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Pelvic venous disorders (PeVD) are an underrecognized yet significant cause of chronic pelvic pain (CPP) in reproductive‐aged women, characterized by venous reflux, obstruction, or both. This clinical opinion provides a practical overview of PeVD for gynecologists, outlining its pathophysiology, common presentations, diagnostic approach, and ...
