Application of the Method of Standard Comparison Problems to Perturbations of the Coulomb Field. ThThe present paper is devoted to obtaining asymptotic expansions for ε → 0 for the eigen-fiinctions Ψ. and eigenvalues E. of Sturm-Liouville problems related to the radial Schrödinger equation . where the potential V(r, ε) is composed of the Coulomb potential and a small perturbation ..

Ebola Virus Disease and Pregnancy: Perinatal Transmission and Epidemiology2%) pregnancies ended in miscarriage, 4 (6%) in stillbirth, and 2 (3%) in elective pregnancy terminations. Overall, 28% of women had an adverse pregnancy outcome, suggesting a long-lasting negative impact of prior EVD on future pregnancies. More research is needed to confirm these findings.
