Translocation of previously accumulated nitrogen and carbohydrates from vegetative tissue of the wheat plant is a major assimilate source for grain filling. This study was conducted to examine genotype differences in nitrogen and fructan translocation and their relationships to grain yield and protein content. Effects indicated that significant genotype differences existed for nitrogen accumulation at anthesis and fructan at milk stage and their translocation. Two high protein genotypes, Cunningham and PST90-19, accumulated more nitrogen before anthesis and had greater nitrogen translocation, but lower post-anthesis nitrogen uptake, than two low protein genotypes, SUN109A and TM56. Among plant parts, leaves were the major storage for tissue nitrogen and provided the overwhelming proportion of the total nitrogen translocation, whereas for fructan accumulation and translocation it was the stems. The two high protein genotypes had a higher percentage of their grain nitrogen derived from nitrogen translocation, while for the two low protein ones, it was from post-anthesis nitrogen uptake and assimilation. Increasing nitrogen application increased nitrogen accumulation and translocation, but decreased fructan accumulation and translocation. High grain protein content was associated with high nitrogen translocation from leaves, stems and the total plant, while high grain yield was related to high fructan translocation from stems and the total plant. Fructan translocation was negatively correlated to grain protein content. Nitrogen and fructan translocation were not correlated with each other.

The Analytic Network Process (ANP) is a multicriteria theory of measurement used to derive relative priority scales of absolute numbers from individual judgments (or from actual measurements normalized to a relative form) that also belong to a fundamental scale of absolute numbers. These judgments represent the relative influence, of one of two elements over the other in a pairwise comparison process on a third element in the system, with respect to an underlying control criterion. Through its supermatrix, whose entries are themselves matrices of column priorities, the ANP synthesizes the outcome of dependence and feedback within and between clusters of elements. The Analytic Hierarchy Process (AHP) with its independence assumptions on upper levels from lower levels and the independence of the elements in a level is a special case of the ANP. The ANP is an essential tool for articulating our understanding of a decision problem. One had to overcome the limitation of linear hierarchic structures and their mathematical consequences. This part on the ANP summarizes and illustrates the basic concepts of the ANP and shows how informed intuitive judgments can lead to real life answers that are matched by actual measurements in the real world (for example, relative dollar values) as illustrated in market share examples that rely on judgments and not on numerical data.

1 Results Palygorskite (PGS) is a chain-layer magnesium-aluminum silicate mineral. Because of its developed interior channels and large specific surface area, and thus considerable adsorption capacity, it has been studied for the application as one of environmental mineral adsorbents[1-3]. Cyclodextrins (CD) possess a hydrophilic exterior and a hydrophobic interior into which a variety of hydrophobic organic molecules maybe introduced. The CD molecule not only affects a hydrophilic cavity on the nanomet...

目的建立高毒力肺炎克雷伯菌经气溶胶肺递送和滴鼻感染金黄地鼠动物模型,并对比两种模型的构建效果。方法选取4~5周龄雄性金黄地鼠,经气溶胶肺递送和滴鼻两种途径攻毒高毒力肺炎克雷伯菌NTUHK2044,记录金黄地鼠攻毒后14 d的生存状况,计算两种途径的半数致死量、存活率,并对呼吸道沉积分布、肺部细菌载量及组织病理进行检测。结果气溶胶肺递送途径攻毒引起金黄地鼠半数死亡剂量(3×10^(4)CFU)低于滴鼻途径(7×10^(5)CFU)。4×10^(6)CFU高毒力肺炎克雷伯菌以气溶胶肺递送途径感染金黄地鼠后,96.46%沉积在肺部并成功定植,主要引起大叶性肺炎,4 d内动物全部死亡;而同等剂量菌液滴鼻后95.62%沉积在口鼻部,随后下移至气管定植,主要引起支气管肺炎,病变程度相对较轻,细菌更易被机体清除,14 d存活率为70%。结论细菌呼吸道感染造模效果受攻毒途径影响,高毒力肺炎克雷伯菌经气溶胶肺递送攻毒主要引起病变严重的大叶性肺炎,滴鼻则主要引起病变较轻的支气管肺炎。上述两种动物模型的成功建立可为肺炎克雷伯菌致病机制研究和药效评价提供关键支撑。

In contrast with conscious decision-making, there are numerous subconscious decisions that we make without thinking about them. Some are biological and are made by different parts of our body to keep it alive and functioning normally. Others are a result of repetition and training that we can then do without thinking about them. The mathematics of conscious decisions with the Analytic Hierarchy and Network Processes is discrete, and has been discussed in the first three parts published on the subject. The mathematics of subconscious decisions is continuous. Here, we generalize the discrete mathematics of conscious decisions to the continuous case and develop it in some depth to apply to the synthesis of firings in the brain.

【目的】在“双碳”目标以及我国能源结构加速转型的双重驱动下,风电产业规模不断快速增长,亟须降本增效以应对平价上网压力。集电线路的造价在投资中占比较大,存在可观的优化空间。为了降低投资成本,提出了一种改进模糊C-均值(fuzzy C-means,FCM)聚类算法。【方法】利用改进FCM聚类算法对陆上风电场集电线路回路进行划分。该算法综合考虑了方位角与欧式距离,以保障回路间线路不交叉,并使相邻机组聚集到同一回路;引入机位到聚类中心距离的修正因子,通过调节其数值限制回路容量。在回路划分的基础上,利用动态Prim算法对各回路进行集电线路优化选线。最后,通过某陆上风电场算例验证方法的有效性。【结果】与只考虑方位角的聚类方法相比,考虑方位角和间距的改进FCM算法优化效果更好,单回、双回连接对应的集电线路总造价分别降低了2.6%和5.4%。【结论】所提算法能够有效降低集电线路的总造价,具有一定的应用价值,可为风电场集电线路设计提供参考。
