radio interferometers are used to construct high resolution images of the sky at radio frequencies and are the key instruments for accessing the statistical properties of the evolution of neutral hydrogen over cosmic time. Here we use simulated observations of the model sky to assess the efficacy of different estimators of the large-scale structure and power spectrum of the sky brightness distribution. We find that while the large-scale distribution can be reasonably estimated using the reconstructed image from interferometric data, estimates of the power spectrum of the intensity fluctuations calculated from the image are generally biased. This bias is found to be more pronounced for diffuse emission. The visibility based power spectrum estimator, however, gives an unbiased estimate of the true power spectrum. This work demonstrates that for an observation with diffuse emission the reconstructed image can be used to estimate the large-scale distribution of the intensity, while to estimate the power spectrum, visibility based methods should be *** the upcoming experiments aimed at measuring the evolution of the power spectrum of the neutral hydrogen distribution, this is a very important result.

[目的]探索自拟方甘草养阴汤(GNY)对咪喹莫特(IMQ)诱导的银屑病样皮肤损伤小鼠模型的疗效。[方法]将小鼠分为健康对照组、模型组(IMQ诱导银屑病小鼠)和治疗组(给予银屑病小鼠GNY,浓度为2.5、5 g/kg);共4组(动物数=8/组)。采用银屑病病灶面积和严重程度指数(PASI)、苏木-精伊红染色和Baker评分用于评估疾病的严重程度。采用免疫组织化学或免疫荧光染色法对真皮的Gr-1,CD11c,rOrγt和TGF-β阳性的炎性细胞进行计数。采用流式细胞仪分析脾脏细胞中的CD4+IL-17+Th17细胞和CD4+CD25+Foxp3+Treg细胞比例。使用qPCr半定量IL-6、IL-10、IL-17A、IL-22、IL-23、TNF-α、TGF-β和AMPK-1的相对mrNA表达。[结果]与模型组相比,GNY治疗的小鼠在两种浓度下均能够改善了病灶的形态学特征,包括PASI评分和上皮角质细胞增生。较高浓度的GNY可显着降低银屑病小鼠模型真皮中的Gr-1,CD11c,rOrγt和TGF-β阳性细胞比例;下调脾脏Th17细胞比例,增加Treg细胞的表达。此外,IMQ模型组小鼠的真皮内IL-6、IL-10、IL-17A、IL-22、IL-23、TNF-α、TGF-β和AMPKɑ1的相对mrNA表达升高,在以5 g/kg浓度的GNY治疗的模型小鼠中表达明显降低。[结论]研究表明GNY可改善IMQ诱导的小鼠银屑病样皮肤损伤表现、减轻炎症反应;为临床治疗银屑病提供依据。

The first enantioselective assembly of sandwich-shaped organo molecules has been achieved by conducting dual asymmetric Suzuki-Miyaura couplings and nine other reactions. This work also presents the first fully C-C anchored multi-layer 3 D chirality with optically pure enantiomers. As confirmed by X-ray diffraction analysis that this chiral framework is featured by a unique C2-symmetry in which a nearly parallel fashion consisting of three layers: top, middle and bottom aromatic rings. Unlike the documented planar or axial chirality, the present chirality shows its top and bottom layers restrict each other from free rotation, i.e., this multi-layer 3 D chirality would not exist if either top or bottom layer is removed. Nearly all multi-layered compounds showed strong luminescence of different colors under UV irradiation, and several randomly selected samples displayed aggregation-induced emission(AIE) properties. This work is believed to have broad impacts on chemical, medicinal and material sciences including optoelectronic materials in future.

Coal is one of the main sources of energy in many parts of the world and has one of the largest reserves/production ratios amongst all the non-renewable energy sources. Gasification of coal is one among the advanced technologies that has potential to be used in a carbon constrained economy. However, gasification availability at several commercial demonstrations had run into problems associated with fouling of syngas coolers due to unpredictable flyash formation and unburnt carbon losses. Computer models of gasifiers are emerging as a powerful tool to predict gasifier performance and reliability, without expensive testing. Most computer models used to simulate gasifiers tend to model coal as a homogenous entity based on bulk properties. However, coal is a heterogeneous material and comminution during feedstock preparation produces particle classes with different physical and chemical properties. It is crucial to characterize the heterogeneity of the feedstocks used by entrained flow gasifiers. To this end, a low ash US bituminous coal that could be used as a gasifier feedstock was segregated into density and size fractions to represent the major mineral matter distributions in the coal. Float and sink method and sieving were employed to partition the ground coal. The organic and inorganic content of all density fractions was characterized for particle size distribution, heating value, ultimate analysis, proximate analysis, mineral matter composition, ash composition, and petrographic components, while size fractions were characterized for heating value, ash composition, ultimate and proximate analysis. The proximate, ultimate and high heating value analysis showed that variation in these values is limited across the range of size fractions, while the heterogeneity is significant over the range of density fractions. With respect to inorganics, the mineral matter in the heavy density fractions contribute significantly to the ash yield in the coal while contributing ver
