PURPOSE To evaluate the performance of four-dimensional (4D) flow-sensitive MRI in the thoracic aorta using 12- and 32-channel coils and parallel imaging. MATERIALS AND METHODS 4D flow-sensitive MRI was performed in the thoracic aorta of 11 healthy volunteers at 3 Tesla (T) using different coils and parallel imaging (GRAPPA) accelerations (R): (i)(More)
The degradation of intracytosolic proteins has been well described. However, the degradation pathway and physiological functions of the DNA-Bound peptides, which are free of degradation by peptidase of the post-ubiquitin-proteasome pathway, are still unclear. In this study, the DNA-Bound peptides were isolated from barley germ and two main fractions of(More)
In this paper, the problem of quantum filtering with two homodyne detection measurements for a two-level system has been considered. The quantum system is driven by two input light field channels, each of which contains a single photon. A quantum filter based on multiple measurements is designed; both the master equations and stochastic master equations are(More)
OBJECTIVE To study the morphological variations of Paris polyphylla var. yunnansensis in different population for genetic diversity and breeding. METHOD The characters of roots, stalks, leave and flowers were observed. The results were analyzed by DPS software. RESULT AND CONCLUSION P. polyphylla var. yunnansensis showed plenty genetic diversity, there(More)
