OBJECTIVES The Surviving Sepsis Campaign has recommended that antibiotic therapy should be started within the first hour of recognizing severe sepsis. Procalcitonin has recently been proposed as a biomarker of bacterial infection, although the quantitative procalcitonin assay is often time consuming, and it is not always available in many emergency(More)
A superlattice structure of planar metamaterial is fabricated, where the orientation of double-split ring resonators is altered in a periodic way. A time-domain terahertz transmission spectrum shows an enhanced Q-factor resonance appears when a closed mode is selectively excited by angular tuning of polarization direction. The polarization-angle selective(More)
BACKGROUND Left ventricular filling pressure (LVFP) is related to the long-term prognosis in end-stage renal disease. The aims of this study were to evaluate the time course of the changes in LVFP, the predictors for the changes of LVFP, and the plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels as indicators for the changes of LVFP in(More)
THz metamaterials are employed to examine changes in the meta-resonances when two anisotropic organic materials, liquid crystal and carbon nanotubes, are placed on top of metamaterials. In both anisotropic double split-ring resonators and isotropic four-fold symmetric split-ring resonators, anisotropic interactions between the electric field and organic(More)
A symmetric metamaterial superlattice is introduced accommodating a high Q-factor trapped mode. THz time-domain spectroscopy is employed to measure the transmission spectra, identifying the excitation of trapped and open-modes in the meta-resonances. A finite-difference-time- domain calculation showed that the trapped mode excitation is from the cancelation(More)
