1Further Information of the Associated Li Deposits in the No.6 Coal Seam at Jungar Coalfield, Inner Mongolia, Northern China显示文摘Total 138 coal samples and 14 parting samples were taken from the No. 6 Seam of the Jungar Coalfield, Inner Mongolia. These samples were analysed by optical microscopy, sequential chemical extraction procedure (SCEP), inductively coupled plasma mass spectrometry (ICP-MS), X-ray powder diffraction (XRD), and scanning electron microscope in conjunction with an energy-dispersive X-ray spectrometer (SEM-EDX) analysis. The results indicate that the Li contents have reached the industrial grade of the coal associated Li deposit, and the total Li reserves have reached 2406600 tons, that is, 5157000 tons Li2O in the No. 6 seam in the Jungar Coalfield. The sequential chemical extraction procedure results suggest that the Li concentration is mainly related to inorganic matter. The minerals in the coals consist of kaolinite, boehmite, chlorite-group mineral, quartz, calcite, pyrite, siderite and amorphous clay material. Some Li could be absorbed by clay minerals in the Li-bearing coal seam. The chlorite phase?could be?most likely the host for a part of Li. The Yinshan Oldland should be the most possible source of Li of the coal.SUN Yuzhuang ZHAO Cunliang LI Yanheng WANG Jinxi ZHANG Jianya JIN Zhe LIN Mingyue Wolfgang KALKREUTH 2013Acta Geologica Sinica(English Edition)2013,87,4:33

3Anomalous Concentrations of Rare Metal Elements, Rare-scattered(Dispersed) Elements and Rare Earth Elements in the Coal from Iqe Coalfield, Qinghai Province, China显示文摘Total of 23 bench samples were taken from the No. 7 Coal of Iqe Coalfield, Qinghai Province, China, following Chinese Standard Method GB/T 482-2008(2008). These samples were analyzed by powder X-ray diffraction(XRD), inductively coupled plasma mass spectrometry(ICPMS) and X-ray fluorescence(XRF). The results indicate that the No. 7 Coal belongs to a low rank(Ro,ran =0.659%) and high-ash coal(40.54%). Compared to common Chinese and world low-rank coals, the Iqe coal contains anomalous concentrations of rare metal elements, rare-scattered(dispersed) elements and rare earth elements. The highest contents of Rb, Cs, Ga and REY reach to 180, 26, 37, and 397 ppm, respectively. Their average contents of these elements are 10.9, 15, 4.8 and 3.5 times higher than those of world coals, respectively. Minerals in the coal include kaolinite, quartz, muscovite, siderite, and traces of rutile, and brookite. Kaolinite could be main host minerals of Rb, Cs, Ga and REY. The anomalous rare element Rb and Cs accumulation in the Iqe coal is related to both organic and inorganic matter. The REY concentrations may be related to circulation of thermal solutions, contained or sorbed by clayey particles, and organic matter as well.SUN Yuzhuang ZHAO Cunliang LI Yanheng WANG Jinxi 2015Acta Geologica Sinica(English Edition)2015,89,1:12

5Adaptive Application Offloading Decision and Transmission Scheduling for Mobile Cloud Computing显示文摘Offloading application to cloud can augment mobile devices' computation capabilities for the emerging resource-hungry mobile application, however it can also consume both much time and energy for mobile device offloading application remotely to cloud. In this paper, we develop a newly adaptive application offloading decision-transmission scheduling scheme which can solve above problem efficiently. Specifically, we first propose an adaptive application offloading model which allows multiple target clouds coexisting. Second, based on Lyapunov optimization theory, a low complexity adaptive offloading decision-transmission scheduling scheme has been proposed. And the performance analysis is also given. Finally, simulation results show that,compared with that all applications are executed locally, mobile device can save 68.557% average execution time and 67.095% average energy consumption under situations.Junyi Wang Jie Peng Yanheng Wei Didi Liu Jielin Fu 2017China Communications2017,14,3:6

7Effects of Joint Controller on Analytical Modal Analysis of Rotational Flexible Manipulator显示文摘Modal analysis is a fundamental and important task for modeling and control of the flexible manipulator. However, almost all of the traditional modal analysis methods view the flexible manipulator as a pure mechanical structure and neglect feedback action of joint controller. In order to study the effects of joint controller on the modal analysis of rotational flexible manipulator, a closed-loop analytical modal analysis method is proposed. Firstly, two exact boundary constraints, namely servo feedback constraint and bending moment constraint, are derived to solve the vibration partial differential equation. It is found that the stiffness and damping gains of joint controller are both included in the boundary conditions, which lead to an unconventional secular term. Secondly, analytical algorithm based on Ritz approach is developed by using Laplace transform and complex modal approach to obtain the natural frequencies and mode shapes. And then, the numerical simulations are performed and the computational results show that joint controller has pronounced influence on the modal parameters: joint controller stiffness reduces the natural frequency, while joint controller damping makes the shape phase non-zero. Furthermore, the validity of the presented conclusion is confirmed through experimental studies. These findings are expected to improve the performance of dynamics simulation systems and model-based controllers.CHU Ming ZHANG Yanheng CHEN Gang SUN Hanxu 2015Chinese Journal of Mechanical Engineering2015,28,3:6

9Deformation in locally convex topological linear spaces显示文摘We are concerned with a deformation theory in locally convex topological linear spaces. A special 'nice' partition of unity is given. This enables us to construct certain vector fields which are locally Lipschitz continuous with respect to the locally convex topology. The existence, uniqueness and continuous dependence of flows associated to the vector fields are established. Deformations related to strongly indefinite functionals are then obtained. Finally, as applications, we prove some abstract critical point theorems.DING Yanheng 2004Science China Mathematics2004,47,5:4
10Homoclinic orbits of first order discrete Hamiltonian systems with super linear terms显示文摘In this paper we consider the first order discrete Hamiltonian systems x1(n + 1)-x1(n) = -Hx2 (n, x(n)), x2(n)-x2(n-1) = Hx1 (n, x(n)), where x(n) =( x1(n) x2(n)) ∈ R2N , H(n1, Z)∈1/2S(n)z·z+R(n1 z) is periodic in n and superlinear as |z| →∞. We prove the existence and infinitely many (geometrically distinct) homoclonic orbits of the system by critical point theorems for strongly indefinite functionals.CHEN WenXiong YANG MinBo DING YanHeng 2011Science China Mathematics2011,54,12:4

12Model for human dynamics based on habit显示文摘The quantitative understanding of human behavior is a central question of modern science. Because of the complexity of human behavior, it is almost impossible to seek regularities in human dynamics. It is assumed that human actions are randomly distributed in time in current models for human dynamics. While the characteristics of human behavior combined with the queue model are considered as model for human dynamics based on habit to explain bursts and heavy tails in human dynamics more exactly. Normal distribution is used to simulate intervals of succession of events, and random parameters are set as unexpected events disturbing habit behaviors. Moreover, duration of events are proposed to imitate continual attention to some events in human behaviors.JIAO Yu LIU YanHeng WANG Jian WANG Jing 2010Chinese Science Bulletin2010,55,24:2
13Chronic inflammation deteriorates structure and function of collagen fibril in rat temporomandibular joint disc显示文摘Collagen is the building component of temporomandibular joint(TMJ) discs and is often affected by inflammation in temporomandibular disorders. The macromechanical properties of collagen are deteriorated by chronic inflammation. However,the mechanism by which inflammation influences disc function remains unknown. The relationship between the ultrastructure and nanomechanical properties of collagen in inflamed discs should be clarified. Seven-week-old female Sprague–Dawley rats were randomly divided into two groups. Chronic TMJ inflammation was induced by intra-articular injection of complete Freund's adjuvant, and samples were harvested after 5 weeks. Picrosirius staining revealed multiple colours under polarized light, which represented alternative collagen bundles in inflamed discs. Using atomic force microscopy scanning, the magnitude of Young's modulus was reduced significantly accompanied with disordered collagen fibril arrangement with porous architecture of inflamed discs. Transmission electron microscopy scanning revealed a non-uniform distribution of collagen fibres, and oversized collagen fibrils were observed in inflamed discs. Fourier transform infrared microspectroscopy revealed a decrease in 1 338 cm^(-1)/amide II area ratio of collagen in different regions. The peak positions of amide I and amide II bands were altered in inflamed discs,indicating collagen unfolding. Our results suggest that sustained inflammation deteriorates collagen structures, resulting in the deterioration of the ultrastructure and nanomechanical properties of rat TMJ discs.Shengjie Cui Yu Fu Yan Liu Xiaoxing Kou Jieni Zhang Yehua Gan Yanheng Zhou Xuedong Wang 2019International Journal of Oral Science2019,11,1:2
