Mie Scattering by a Conducting Sphere Coated Uniaxial Single-Negative Medium by You-Lin Geng

“…We propose an accurate analytical method to compute the electromagnetic scattering from three-dimensional (3D) conducting sphere coated uniaxial anisotropic single-negative (SNG) medium. Based on the spherical vector wave functions (SVWFs) in uniaxial anisotropic medium, the electromagnetic field in homogeneous uniaxial SNG medium and free space can be expressed by the SVWFs in uniaxial SNG medium and free space. …”

Serum Growth Differentiation Factor 15 is Negatively Associated with Leukocyte Telomere Length by Jie Yu, Yiwen Liu, Huabing Zhang, Fan Ping, Wei Li, Lingling Xu, Yuxiu Li

“…In correlation analysis, GDF15 was positively correlated with age, while LTL and mtDNAcn were negatively correlated with age.After adjusting for confounding factors,GDF15 was negatively associated with LTL (β = −0.120, 95%CI [−0.197, −0.042], p = 0.003) and the association was linear(p for nonlinear = 0.645), while the negative association between GDF15 and mtDNAcn did not reach significance.In the stratified analyses,the negative associations between GDF15 and LTL were more prominent in women, overweight individuals, or subjects with abnormal glucose tolerance (AGT), but similar results were observed in younger and older subjects. …”
