First-principles study of L-shell iron and chromium opacity at stellar interior temperatures.
Karasiev VV, Hu SX, Shaffer NR, Miloshevsky G. Karasiev VV, et al. Among authors: shaffer nr. Phys Rev E. 2022 Dec;106(6-2):065202. doi: 10.1103/PhysRevE.106.065202. Phys Rev E. 2022. PMID: 36671100
It is demonstrated that the role of XC at such a high-T is negligible due to the total free energy of interacting systems being dominated by the noninteracting free-energy term, in agreement with estimations for the homogeneous electron gas. ...

Should HIV testing for all pregnant women continue? Cost-effectiveness of universal antenatal testing compared to focused approaches across high to very low HIV prevalence settings.
Ishikawa N, Dalal S, Johnson C, Hogan DR, Shimbo T, Shaffer N, Pendse RN, Lo YR, Ghidinelli MN, Baggaley R. Ishikawa N, et al. Among authors: shaffer n. J Int AIDS Soc. 2016 Dec 14;19(1):21212. doi: 10.7448/IAS.19.1.21212. eCollection 2016. J Int AIDS Soc. 2016. PMID: 27978939 Free PMC article.
CONCLUSIONS: Universal approach to antenatal HIV testing achieves the best health outcomes and is cost-saving or cost-effective in the long term across the range of HIV prevalence settings. It is further a prerequisite for quality maternal and child healthcare and for the …

PMID: 25371480 Free PMC article.
Findings were adjusted for non-response, survey design and weighted for live-birth distributions. RESULTS: Nationally, 32% of live infants were HEI; early mother-to-child transmission (MTCT) was 3.5% (95% CI 2.9% to 4.1%). ...CONCLUSIONS: SA, a high-HIV-prevalence middle i …

Infected infants had significantly higher rates of prematurity (gestational age less than 37 weeks) (33% vs 19%, P = .01) and extreme prematurity (gestational age less than 34 weeks) (18% vs 6%, P = .001) than uninfected infants. Infection was associated with lower birth w …
