Exploring Regional Ecological Cultures in the Upper Reaches of the Yellow River in the Ming and Qing Dynasties from the Perspective of "Top Eight Views"

By studying typical "Top Eight Views" in cities like Xining,Lanzhou and Yinchuan in the upper reaches of the Yellow River,mountain and water landscapes in the study area were analyzed in terms of natural ecology;bridges,canals,ferries,pavilions,mansions,towers,temples,historical sites,production and living landscapes were analyzed in terms of humanistic ecology.On this basis,"Top Eight Views" in the upper reaches of the Yellow River were compared and the following conclusions obtained:mountain landscapes were distributed in the whole region,waterscapes unevenly valued in different cities,bridges,canals and ferries mostly located in Ningxia,temples commonly found in all cities,garden arts introduced into cities,traditional cultures carried forward by historical relics.Then the relationship between "Top Eight Views" and regional eco-cultures was analyzed,and it was proposed that humanistic and cultural connotations of these "Top Eight Views" contributed a lot to beautifying urban environment,satisfying needs of the locals' spiritual life,carrying forward local history and culture,enriching urban cultural connotations,expanding living spaces of local residents and improving integrated functions of cities."Top Eight Views" culture complied with the construction gist of urban ecological cultures,and was of great referential value for the construction of urban ecological cultures in the upper reaches of the Yellow River,and also the healthy,scientific and sustainable development of local cities.

Linkage analysis and integrated software GAPL for pure-line populations derived from four-way and eight-way crosses

Pure lines derived from multiple parents provide abundant variation for genetic study.However,efficient genetic analysis methods and user-friendly software are still lacking.In this study, we developed linkage analysis methods and integrated analysis software for pure-line populations derived from four-way and eight-way crosses.First, polymorphic markers are classified into different categories according to the number of identifiable alleles in the inbred parents.Expected genotypic probability is then derived for each pair of complete markers, and based on them a maximum likelihood estimate(MLE) of recombination frequency is calculated.An EM algorithm is proposed for calculating recombination frequencies in scenarios that at least one marker is incomplete.A linkage map can thus be constructed using estimated recombination frequencies.We describe a software package called GAPL for recombination frequency estimation and linkage map construction in multi-parental pure-line populations.Both simulation studies and results from a reported four-way cross recombinant inbred line population demonstrate that the proposed method and software can build more accurate linkage maps in shorter times than other published software packages.The GAPL software is freely available from www.isbreeding.net and can also be used for QTL mapping in multi-parental populations.

Grey Relevancy Degree and Improved Eight-Direction Sobel Operator Edge Detection

Edge detection is an important aspect to improve image edge quality in image processing. The purpose of edge detection is to identify the points in digital images with great brightness variation. However, the accuracy of traditional edge detection methods in edge extraction is low. For the actual image, the grey edge is sometimes not very clear, the image also contains noise. The detection result of the traditional Sobel operator is relatively accurate, but the detection result is rough and sensitive to noise. To solve the above problems, this paper proposes an improved eight-direction Sobel operator based on grey relevancy degree, which combines 5 × 5 Sobel operator with a grey relational degree and a new eight-direction grey relevancy method. The results show that this method can detect the useful information of edge more accurately and improve the anti-noise performance. However, the drawback is that the algorithm is not automatic.

The title compound [Mn（O2CMe）2（phen）2] （phen = 1,10-phenanthroline） 1 has been synthesized and structurally determined by single-crystal X-ray diffraction. The crystal is of orthor- hombic, space group Pbcn, with a = 12.554（4）, b = 10.168（3）, c = 17.704（5）A, V= 2259.7（12）A^3 Z = 4, C28H22MnN4O4, Mr= 533.44, Dc= 1.568 g]cm^3, F（000） = 1100, Rint = 0.0242, T= 293（2） K and p = 0.631 mm^-1. The final R = 0.0687 and wR = 0.1960 for 2046 observed reflections with I 〉 20（/）. The structure of the complex consists of one Mn（II） core coordinated by two bidentate-bound CH3COO^- groups and two η^2-phen groups forming an eight-coordinate geometrical configuration.

A New Eight-connected Three-dimensional Network Based on a Tetranuclear Zinc Cluster Building Block

One interesting coordination polymer, [Zn2（1,2,4-BTC）（OH）（H2O）2]2·2H2O 1, has been synthesized from 1,2,4-BTC （1,2,4-BTC = 1,2,4-bentricarboxylate） under hydrothermal conditions and characterized by elemental analyses, IR, TG and single-crystal X-ray diffraction. Complex I crystallizes in triclinic, space group P^-1, with a = 6.5200（13）, b = 9,0600（18）, c = 10.968（2） A^°, α = 111.55（3）, β = 92.07（3）,γ= 95.03（3）°, C9H10O10Zn2, Mr = 408.91, V= 598.7（2） A^°^3, Dc = 2.268 g/cm^3, F（000） = 408 and Z = 2. X-ray diffraction analysis reveals that complex 1 is a three-dimensional network built from tetranuclear Zn（Ⅱ） building unit. In this complex, the Zn4 unit is an eight-connected knot, while 1,2,4-BTC a four-connected knot. This results in a CaF2 topology. To the best of our knowledge, such Zn4 unit is the first 8-connected building block built from asymmetry ligand.

Numerical study of strained InGaAs quantum well lasers emitting at 2.33 μm using the eight-band model

We investigate the band structure of a compressively strained In（Ga）As/In0.53Ga0.47As quantum well （QW） on an InP substrate using the eight-band k.p theory. Aiming at the emission wavelength around 2.33 μm, we discuss the influences of temperature, strain and well width on the band structure and on the emission wavelength of the QW. The wavelength increases with the increase of temperature, strain and well width. Furthermore, we design an InAs /In0.53Ga0.47As QW with a well width of 4.1 nm emitting at 2.33 μm by optimizing the strain and the well width.

Modeling and Robust Backstepping Sliding Mode Control with Adaptive RBFNN for a Novel Coaxial Eight-rotor UAV

This paper focuses on the robust attitude control of a novel coaxial eight-rotor unmanned aerial vehicles (UAV) which has higher drive capability as well as greater robustness against disturbances than quad-rotor UAV. The dynamical and kinematical model for the coaxial eight-rotor UAV is developed, which has never been proposed before. A robust backstepping sliding mode controller (BSMC) with adaptive radial basis function neural network (RBFNN) is proposed to control the attitude of the eightrotor UAV in the presence of model uncertainties and external disturbances. The combinative method of backstepping control and sliding mode control has improved robustness and simplified design procedure benefiting from the advantages of both controllers. The adaptive RBFNN as the uncertainty observer can effectively estimate the lumped uncertainties without the knowledge of their bounds for the eight-rotor UAV. Additionally, the adaptive learning algorithm, which can learn the parameters of RBFNN online and compensate the approximation error, is derived using Lyapunov stability theorem. And then the uniformly ultimate stability of the eight-rotor system is proved. Finally, simulation results demonstrate the validity of the proposed robust control method adopted in the novel coaxial eight-rotor UAV in the case of model uncertainties and external disturbances. © 2014 Chinese Association of Automation.

基于改进RANSAC-EightPoint算法的单目视觉的自动初始化方法

为解决利用单目相机估计相机位姿时产生的尺度问题和尺度不统一带来的影响,需通过初始化方法来固定尺度,而初始化方法应无需人为选择两张良好的图片来进行初始化且要有良好的鲁棒性,提出了一种基于改进RANSAC-EightPoint算法的自动初始化方法 ,可自动选择有显著视差的两张图片进行初始化。通过随机采样一致性(Random Sample Concensus,RANSAC)与八点法(Eight-point-algorithm)结合的改进RANSAC-Eight Point算法来估计两图像间的位姿,使得对带有错误匹配的数据也有较准确的估计值。最后采用标准测试数据集和自己采集数据对该方法进行测试,并比较了利用该初始化方法后获得的轨迹和无初始化方法获得的轨迹与真实轨迹之间的差异。实验结果表明该方法都能对这些数据集完成初始化,通过该方法后所得到的轨迹具有全局一致性。

“体用排偶”与明清制义的文体特征

“制义”是明清科举考试中经义文体的正式名称,“八股文”则是对经义文体的俗称。明代官方正式文件从不称其科举文体为“八股文”,明代的经义文集一般不以“八股文”为书名,“八股文”一词不能准确、全面揭示明清经义文的文体性质和特点。《明史·选举志》指出“体用排偶”是明代制义主体部分的文体形态特点。“排偶”包括排比和骈偶,骈偶类包括两扇、四段、六股、八股、十股、十二股、十六股等。在排比类中存在着一种股数为奇数的排比形态,如三股文、五股文、七股文、九股文,可统称为“奇股文”。奇股文的存在应引起我们重视,明清制义文体的本质与特点需要重新认识。决定明、清制义“排偶”部分文体形态的,是题目的句型结构特点和语义结构特点。当然,作者的修辞理念和兴趣也对其“排偶”设置产生影响。明代成化之后,八股形态在“排偶”诸形态中占据主流地位,这既与它契合传统文章学理念有关,也与科举考试的标准化进程是相呼应的。
