“The frequency dependence of magnetization precession in spin pumping has been investigated using the inverse spin-Hall effect in a Pt/Y3Fe5O12
bilayer film. We found that the magnitude of a spin current generated by the spin pumping depends weakly on selleck kinase inhibitor the applied microwave frequency. This weak dependence, which is attributed to the compensation between the frequency change in the spin-pumping cycle and the dynamic magnetic susceptibility, is favorable for making a spin-current-driven microwave demodulator. This behavior is consistent with a model calculation based on the Landau-Lifshitz-Gilbert equation combined with the spin mixing. (C) 2011 American Institute of Physics. [doi:10.1063/1.3594661]“
“PURPOSE To investigate
the causes of nonphysiologic behavior of the SRK/T formula, assess their clinical significance, and develop and evaluate solutions
SETTING Two NHS ophthalmology departments, United Kingdom, and a private practice, United States
DESIGN Evaluation of technology
METHODS The individual steps of the SRK/T formula were examined for nonphysiologic behavior, and the clinical significance of behaviors was assessed with reference to a database of biometry and refractive outcomes in 11 189 eyes The full data set was divided into 2 subsets, the first to develop solutions to nonphysiologic behavior of the SRK/T formula and the second to evaluate their performance
RESULTS ThE SRK/T formula showed nonphysiologic behavior in the calculation of corrected axial length and corneal height Although the former is of little clinical significance, the latter showed Selleckchem BKM120 a systematic error that contributes to HIF inhibitor inaccurate
intraocular lens (IOL) power prediction The T2 formula was developed using a regression formula for corneal height derived from the development subset Comparison of the performance of the T2 and SRK/T formulas using the evaluation subset showed significant improvement in the mean absolute error with the 12 formula (0 3064 diopter [D] versus 0 3229 D, P< 0001) On average, the prediction error with the T2 formula was 9 7% less than with the SRK/T formula, with significantly higher proportions of eyes within +/- 0 50 D of target (P< 0001)
CONCLUSIONS The SRK/T formula has nonphysiologic behavior that contributes to IOL power prediction errors A modification to the formula algorithm, the T2 formula, can be directly substituted for SMUT, resulting in significantly improved prediction accuracy”
“To determine the usefulness of MspI/int22h-1 (intron 22 homologous region-1) polymorphism of the factor VIII gene for molecular genetic diagnosis of hemophilia A in the Korean population, MspI/intron 22 and XbaI/intron 22 polymorphisms were analyzed in 101 unrelated Korean families with severe hemophilia A. The expected heterozygosity rates of MspI/int22h-1 and XbaI/ int22h-1 polymorphisms were 49.5 and 43.
