BACKGROUND We investigate whether plasma homocysteine (HCY) levels are associated with hematoma volume and outcome in patients with intracerebral hemorrhage (ICH). METHODS A total of 69 patients admitted within 24 hours after ICH onset was divided into 2 groups based on admission plasma HCY levels (low homocysteinemia [LHCY] group, plasma HCY(More)
A rigorous full wave analysis of bianisotropic split ring resonator (SRR) metamaterials is presented for different electromagnetic field polarization and propagation directions. An alternative physical explanation is gained by revealing the fact that imaginary wave number leads to the SRR resonance. Metamaterial based parallel plate waveguide and(More)
As a kind of high resolution radar, Synthetic Aperture Radar (SAR) is very important in many military applications. Frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR), combining FMCW technique with synthetic aperture imaging methods, is a newly proposed imaging radar system, and has the advantages such as small cubage, light weight,(More)
