PURPOSE To develop a magnetization preparation sequence for simultaneous outer volume suppression (OVS) and T2 weighting in whole-heart coronary magnetic resonance angiography. METHODS A combined OVS and T2 preparation sequence (OVS-T2 Prep) was designed with a nonselective adiabatic 90° tipdown pulse, two adiabatic 180° refocusing pulses, and a 2D spiral(More)
— A semianalytical carbon nanotube field-effect transistor (CNFET) model based on the virtual-source model is presented, which includes series resistance, parasitic capacitance, and direct source-to-drain tunneling leakage. The model is calibrated with recent experimental data down to 9-nm gate length. Device performance of 22-to 7-nm technology nodes is(More)
PURPOSE To develop a method for acquiring whole-heart 3D image-based navigators (iNAVs) with isotropic resolution for tracking and correction of localized motion in coronary magnetic resonance angiography (CMRA). METHODS To monitor motion in all regions of the heart during a free-breathing scan, a variable-density cones trajectory was designed to collect(More)
OBJECTIVE To establish the theories and methods to determine apparent solubility paraneters of multiple components for the Chinese materia medica (CMM) with HPLC fingerprint. METHOD The mathematical functional expresses to determine the apparent solubility parameters for multiple constituents were established according to total quantum geometrical average(More)
OBJECTIVE To establish the method for determining muscone in rat intestinal perfusate by GC-MS/MS and study its intestinal absorption kinetic characteristics in rats. METHOD The GC-MS/MS method was used to determine the content of muscone in rat intestinal circulation fluid. In situ intestinal circulation perfusion was adopted to study absorption kinetics(More)
OBJECTIVE To study the solubility peak and dielectric requirement of the Buyang Huanwu docoction materials, and provide theoretical and experimental foundation for selecting extraction solvent for extracting traditional Chinese drugs (TCD). METHOD 11 types of solvents were employed as single or complex solvent systems, whose solubility parameter and(More)
OBJECTIVE To investigate the optimal separation of the total flavones from Herba Epimedii by macroporous adsorption resin. METHOD Nine types of macroporous adsorption were evaluated for separating efficiency by measuring the adsorption ratio, eluting ratio of total flavones. RESULT The D-101 macroporous adsorption resin had the best separating(More)
PURPOSE To develop a retrospective nonrigid motion-correction method based on 3D image-based navigators (iNAVs) for free-breathing whole-heart coronary magnetic resonance angiography (MRA). METHODS The proposed method detects global rigid-body motion and localized nonrigid motion from 3D iNAVs and compensates them with an autofocusing algorithm. To model(More)
