卞之琳着眼于时代背景,在扎根传统文化的同时,寻求与西方诗人艾略特“非个人化”理论的契合点,在20世纪30年代创作了众多具有独特审美韵味的诗歌。在他的经典之作《十年诗草(1930—1939)》中,卞之琳以微观视角中的日常物象重构意象语言,以戏剧化的表达策略构建诗歌形体,强调用客观化的抒情方式来突出情境的张力,认为诗歌中的情感应当升华为超越个人化存在的具有普遍意义的情感,诗歌要以更加客观化的方式关怀社会人生,以更纯粹的理念表征世界、平衡秩序。

It becomes increasingly clear that non-uniform distribution of immiscible fluids in porous rock is particularly relevant to seismic wave dispersion. White proposed a patchy saturation model in 1975, in which spherical gas pockets were located at the center of a liquid saturated cube. For an extremely light and compressible inner gas, the physical properties can be approximated by a vacuum with White＇s model. The model successfully analyzes the dispersion phenomena of a P-wave velocity in gas-water- saturated rocks. In the case of liquid pocket saturation, e.g., an oil-pocket surrounded by a water saturated host matrix, the light fluid-pocket assumption is doubtful, and few works have been reported in White＇s framework. In this work, Poisson＇s ratio, the bulk modulus, and the effective density of a dual-liquid saturated medium are formulated for the heterogeneous porous rocks containing liquid-pockets. The analysis of the difference between the newly derived bulk modulus and that of White＇s model shows that the effects of liquid-pocket saturation do not disappear unless the porosity approaches zero. The inner pocket fluid can no longer be ignored. The improvements of the P-wave velocity predictions are illustrated with two examples taken from experiments, i.e., the P-wave velocity in the sandstone saturated by oil and brine and the P-wave velocity for heavy oils and stones at different temperatures.

针对磁共振图像重建后边缘模糊、纹理不清晰等问题,提出一种混合正则约束项的图像重建模型。利用稀疏表示更为逼近L_0范式的最大最小非凸全变分和对纹理细节保持效果更好的剪切波变换作为约束项构建重建模型,并使用交替方向乘子算法对新模型进行数值求解。实验结果表明,该模型不论是主观视觉效果,还是峰值信噪比和结构相似度等评价标准均优于其他对照模型,不仅能保留图像的纹理信息,同时有效地保留图像边缘信息。

目的探讨高强度深度学习图像重建算法(DLIR-H)在动态心肌灌注(CTP)的应用及其冠状动脉CT血管成像(CCTA)提取的可行性。方法2021年10月至2022年10月前瞻性收集就诊于郑州大学第一附属医院,并在GE Apex CT上进行传统CCTA及动态CTP检查的41例确诊或疑似冠心病患者。传统CCTA采用100 kVp管电压扫描,以DLIR-H重建原始图像;动态CTP采用80 kVp管电压扫描,分别以自适应统计迭代重建算法(ASiR-V)100%和DLIR-H重建原始图像。对比ASiR-V 100%和DLIR-H的静息、负荷CTP的主观及客观评分及心肌血流量(MBF)值。以血管为单位分析主观、客观评分,以及狭窄程度及冠状动脉CT血流储备分数(CT-FFR)值,对比传统CCTA和DLIR-H CTP下提取的单期CCTA(SP-CCTA)的图像质量及诊断性能。统计学分析采用配对t检验、Wilcoxon符号秩和检验和χ^(2)检验。结果在静息和负荷CTP主观图像质量分析中,DLIR-H较高于ASiR-V 100%,差异有统计学意义(P均0.05)。与传统CCTA相比,SP-CCTA的血管CT值升高15.12%,噪声值升高32.27%,主观评分也稍低(4.23±0.05)。但SP-CCTA的总斑块体积、最大狭窄程度、CT-FFR阳性血管支数与传统CCTA差异无统计学意义(P均>0.05)。结论DLIR在动态CTP上不仅可以一定程度上提高原始图像质量,还可以提取高质量的单期CCTA以满足临床诊断,实现“一站式”动态心肌灌注检查,将来有助于简化检查流程,降低对比剂及辐射剂量。

Oligodendrocyte is a highly specialized glial cell type in the vertebrate central nervous system, which guarantees the long-distance transmission of action potential by producing myelin sheath wrapping adjacent axons. Disrupted myelin and oligodendrocytes are hallmarks of some devastating neurological diseases, such as multiple sclerosis, although their contribution to neurodegeneration in a given disease is still controversial. However, accumulating evidence from clinical studies and genetic animal models implicates oligodendrocyte dysfunction as one of major events in the processes of initiation and progression of neurodegeneration. In this article, we will review recent progress in understanding non-traditional function of oligodendrocytes in neuronal support and protection independent of myelin sheath and its possible contribution to neurodegeneration. Oligodendrocytes play a pivotal role in neurodegenerative diseases among which special emphasis is given to multiple system atrophy and Alzheimer＇s disease in this review.
