“Magnetic properties of hard/soft stacked dot arrays consisting of thin Co/Pt superlattice hard layers (3.6 nm in thickness, uniaxial magnetic anisotropy, K(u) = 1.3 X 10(7)

erg/cm(3)) and Co soft layers, with dot diameters of 30-40 nm, were investigated see more as functions of Co soft layer thickness and the interfacial exchange coupling between the hard and soft layers. Pt was used as the control layer of the interfacial exchange coupling, and Co soft layers were sandwiched with Pt layers to induce surface anisotropy on the Co soft layers. The remanence coercivity, H(r), was 2.7 kOe for Co/Pt(3.6 nm)/Co(4nm) stacked dot arrays and 3.2 kOe for Co/Pt(3.6 nm)/Pt(1.2 nm)/Co(3 nm) stacked dot arrays, and these values were less than half that of single hard layer dot arrays (7.1 kOe). H(r) was nearly constant in the phi range from 0 degrees to about 45 degrees (phi is

the applied field angle from the easy axis), and increased significantly as phi increased further, as theoretically predicted. Hard/soft dot arrays maintained a relatively large K(u) due to the surface anisotropy of the Co soft layers. It was suggested that the ratio of magnetic energy to the thermal energy, K(u)(eff)V/kT, for Co/Pt(3.6 nm)/Pt(1.2 nm)/Co (3 nm) hard/soft dot arrays learn more was 1.5 times larger than that for Co/Pt(3.6 nm) single dot arrays because of the relatively large Ku.

“Background-Although sudden cardiac death (SCD) is heritable, its genetic underpinnings are poorly characterized. The QT interval appears to have a graded relationship to SCD, and 35% to 45% of its variation is heritable. We examined XMU-MP-1 manufacturer the relationship among recently reported common genetic variants, QT interval, and SCD.

Methods and Results-We genotyped 15 common

(minor allele frequency >1%) candidate single nucleotide polymorphisms (SNPs), based on association with the QT interval in prior studies, in individuals in 2 cohort studies (Health 2000, n = 6597; Mini-Finland, n = 801). After exclusions, we identified 116 incident SCDs from the remaining sample (n = 6808). We constructed a QT genotype score (QT(score)) using the allele copy number and previously reported effect estimates for each SNP. Cox proportional hazards models adjusting for age, sex, and geographical area were used for time to SCD analyses. The QT(score) was a continuous independent predictor of the heart rate-corrected QT interval (P < 10(-107)). Comparing the top with the bottom quintile of QT(score), there was a 15.6-ms higher group mean QT interval (P < 10 (84)). A 10-ms increase in the observed QT interval was associated with an increased risk of SCD (hazard ratio, 1.19; 95% confidence interval, 1.07 to 1.32; P = 0.002).
