| 1 | Evaluation of Glycosaminoglycan in the Lumbar Disc Using Chemical Exchange Saturation Transfer MR at 3.0 Tesla:Reproducibility and Correlation with Disc Degeneration显示文摘Objective This study aims to explore the clinical applicability and relevance of glycosaminoglycan Chemical Exchange Saturation Transfer(gag CEST) for intervertebral disc. Methods 25 subjects ranging in age from 24 yrs to 74 yrs were enrolled. gag CEST was acquired using a single-slice TSE sequence on a 3T. Saturation used a continuous rectangular RF pulse with B1=0.8 μT and a fixed duration time =1100 ms. Sagittal image was obtained firstly without saturation pulse, and then saturated images were acquired at 52 offsets ranging from ±0.125 to ±7 parts per million(ppm). MR T2 relaxivity map was acquired at the identical location. Six subjects were scanned twice to assess scan-rescan reproducibility. Results Gag CEST intraclass correlation coefficient(ICC) of six subjects was 0.759 for nucleus pulposus(NP) and 0.508 for annulus fibrosus(AF). Bland-Altman plots showed NP had a mean difference of 0.10%(95% limits of agreement:-3.02% to 3.22%); while that of AF was 0.34%(95% limits of agreement:-2.28% to 2.95%). For the 25 subjects, gag CEST in NP decreased as disc degeneration increased, with a similar trend to T2 relaxivity. Gag CEST of AF showed a better correlation with disc degeneration than T2 relaxivity. Conclusion Gag CEST in NP and AF decreased as disc degeneration increased, while gag CEST in AF showed a better correlation than T2 relaxivity. | Deng Min Yuan Jing Chen Wei Tian Queenie Chan James F Griffith Wang Yi Xiang | 2016 | Biomedical and Environmental Sciences2016，29，1： | 8 |
| 2 | A Power and Area Optimization Approach of Mixed Polarity Reed-Muller Expression for Incompletely Specified Boolean Functions显示文摘力量和芦苇思考(RM ) 电路的区域优化广泛地被担心了。然而,几乎没有退出的力量和区域,优化来临能获得所有 Pareto 原版的最佳的答案问题并且足够有效。而且,他们没认为 dont 是照顾术语,它使电路成为性能不能进一步优化。在这糊,我们建议混合极性 RM 的一条力量和区域优化途径为不完全地指定的布尔功能的表示(MPRM ) 基于非统治的排序基因算法 II (NSGA-II ) 。第一,不完全地指定的布尔功能不完全地被转变成零极性由使用的指定 MPRM (ISMPRM ) 一篇小说 ISMPRM 获得算法。第二,极性和分配 ISMPRM 的照顾术语没作为染色体被编码。最后, Pareto 最佳的答案被使用 NSGA-II 获得,在里面哪个 MPRM 相应于给定的染色体被使用一个染色体获得变换算法。结果上重要力量和区域改进能与存在力量和区域优化相比被做的电路表演 RM 接近的不完全地指定的布尔功能和 MCNC 基准电路。 | Zhen-Xue He Li-Min Xiao Li Ruan Fei Gu Zhi-Sheng Huo Guang-Jun Qin Ming-Fa Zhu F Long-Bing Zhang Rui Liu Xiang Wang | 2017 | Journal of Computer Science & Technology2017，32，2： | 4 |
