purpose: to report the refractive changes after intraocular lens (iol) implantation in children with congenital and developmental cataract. methods: in this historical cohort study, the clinical records of children between 2 and 15 years old that had lensectomy with posterior capsulotomy, anterior vitrectomy and iol implantation with more than 5 years of follow-up were studied. refractive error...

Accuracy of "corrected Deser" and "summed up formulas was checked for the $K^- p$ d$ systems. It found that last one is much more accurate should be used connection $1s$ level shift to corresponding scattering length.

Long binary sequences related to cyclic difference sets are investigated. Among all known constructions of cyclic difference sets we show that only sequences constructed from Hadamard difference sets can have an asymptotic nonzero merit factor. Maximal length shift register sequences, Legendre, and twin-prime sequences are all constructed from Hadamard difference sets. We prove that the asympto...

This study evaluated whether small shifts in cardiac autonomic balance with standing, as measured by heart rate variability (HRV), were prospectively associated with incident coronary heart disease (CHD) and mortality. Both Black and White men and women aged 45-64 years from the Atherosclerosis Risk in Communities Study (n = 9,267) were followed from 1987 to 1997 for myocardial infarction (n = ...
