We let Ta and Ma denote respectively the values of the time-to-event outcome and mediator that would have been observed had the exposure A been set to level a. We let Tam denote the value of the time-to-event outcome that would have been observed had the exposure, A, and mediator, M , been set to levels a and m, respectively. The average controlled direct effect comparing exposure level a to a∗...

OBJECTIVE To optimize and standardize an enzyme-linked immunosorbent assay (ELISA) for rapid diagnosis of human brucellosis in clinical cases identified during a surveillance study for acute febrile illness (AFI). METHODS Serum samples from patients presenting with AFI at 13 fever hospitals across Egypt between 1999 and 2003 were kept frozen at NAMRU-3 and used in this study. The assay was ev...

Nanocrystalline W-Ta-Cr-V high entropy alloys have shown promising properties as nuclear fusion materials with enhanced radiation resistance to heavy ion irradiation and negligible hardening. In this work, we investigate the performance of alloy under low energy helium (He) implantation up a fluence 1.25 × 1017 cm?2 at 1223 K. We observe uniform density very small (~2–3 nm) bubbles grown slow r...
