| 1 | Characteristics of leaching of heavy metals from low-sulfur coal gangue under different conditions显示文摘Coal gangue is the main pollution source of mining areas.When coal gangue is stacked and recycled,the heavy metal elements contained in it are released by natural weathering and leaching,which causes damage to the surrounding ecological environment.In this study,the leaching and precipitation characteristics of heavy metals in low-sulfur coal gangue under different environmental conditions were simulated by indoor dynamic leaching experiments,which provided a theoretical basis for environmental restoration of the mining area.The conclusions are as follows:higher heavy metal content in low-sulfur coal gangue is associated with greater,leaching of heavy metals;acidic conditions promote the release of heavy metals in low-sulfur coal gangue;and more precipitation is associated with better release of heavy metals from the low-sulfur coal gangue. | Chang Li Liugen Zheng Chunlu Jiang Xing Chen Shuaishuai Ding | 2021 | International Journal of Coal Science & Technology2021，8，4： | 6 |
| 2 | A BP neural network based information fusion method for urban traffic speed estimation显示文摘Obtaining comprehensive and accurate information is very important in intelligent traffic system (ITS). In ITS, the GPS floating car system is an important approach for traffic data acquisition. However, in this system, the GPS blind areas caused by tall buildings or tunnels could affect the acquisition of traffic information and depress the system performance. Aiming at this problem, a novel method employing a back propagation (BP) neural network is developed to estimate the traffic speed in the GPS blind areas. When the speed of one road section is lost, the speed of its related road sections can be used to estimate its speed. The complete historical data of these road sections are used to train the neural network, using Levenberg-Marquardt learning algorithm. Then, the current speed of the related roads is used by the trained neural network to get the speed of the road section without GPS signal. We compare the speed of the road section estimated by our method with the real speed of this road section, and the experimental results show that the proposed method of traffic speed estimation is very effective. | Qiu Chenye Zuo Xingquan Wang Chunlu Wu Jianping | 2010 | Engineering Sciences2010，8，1： | 6 |

| 5 | Toll-Like Receptor 4 Deficiency Causes Reduced Exploratory Behavior in Mice Under Approach-Avoidance Conflict显示文摘Abnormal approach-avoidance behavior has been linked to deficits in the mesolimbic dopamine(DA)system of the brain. Recently, increasing evidence has indicated that toll-like receptor 4(TLR4), an important pattern-recognition receptor in the innate immune system,can be directly activated by substances of abuse, resulting in an increase of the extracellular DA level in the nucleus accumbens. We thus hypothesized that TLR4-dependent signaling might regulate approach-avoidance behavior. To test this hypothesis, we compared the novelty-seeking and social interaction behaviors of TLR4-deficient(TLR4^(-/-))and wild-type(WT) mice in an approach-avoidance conflict situation in which the positive motivation to explore a novel object or interact with an unfamiliar mouse was counteracted by the negative motivation to hide in exposed,large spaces. We found that TLR4^(-/-)mice exhibitedreduced novelty-seeking and social interaction in the large open spaces. In less stressful test apparatuses similar in size to the mouse cage, however, TLR4^(-/-)mice performed normally in both novelty-seeking and social interaction tests. The reduced exploratory behaviors under approachavoidance conflict were not due to a high anxiety level or an enhanced fear response in the TLR4^(-/-)mice, as these mice showed normal anxiety and fear responses in the open field and passive avoidance tests, respectively. Importantly,the novelty-seeking behavior in the large open field induced a higher level of c-Fos activation in the nucleus accumbens shell(NAc Sh) in TLR4^(-/-)mice than in WT mice. Partially inactivating the NAc Sh via infusion of GABA receptor agonists restored the novelty-seeking behavior of TLR4^(-/-)mice. These data suggested that TLR4 is crucial for positive motivational behavior under approach-avoidance conflict. TLR4-dependent activation of neurons in the NAc Sh may contribute to this phenomenon. | Chunlu Li Yixiu Yan Jingjing Cheng Gang Xiao Jueqing Gu Luqi Zhang Siyu Yuan Junlu Wang Yi Shen Yu-Dong Zhou | 2016 | Neuroscience Bulletin2016，32，2： | 5 |
| 6 | Effects of 1-MCP on proline,polyamine,and nitric oxide metabolism in postharvest peach fruit under chilling stress显示文摘Peach(Prunus persica Batsch‘Yuhualu’)fruit are sensitive to chilling injury(CI).Proline,polyamine(PA),and nitric oxide(NO)are important small regulators of various metabolic pathways under chilling stress that mitigate CI.Ethylene is known to promote senescence and CI,while 1-methylcyclopropene(1-MCP)is an antagonist that inhibits the effects of ethylene.However,how1-MCP and ethylene affect proline,PA,and NO levels under chilling stress remains unclear.To address these questions,1-MCP(1μL·L^(−1))and ethylene(1μL·L^(−1))treatments were applied to peach fruit.Fruit were stored at 4°C for 28 d,then moved to 25°C for 3 d immediately after cold storage.Peach fruit exhibited CI symptoms after 7 d of cold storage with enhanced electrolyte leakage and malondialdehyde contents.The 1-MCP treatment significantly(P<0.05)restrained peach CI,and fruit did not exhibit CI symptoms until 14 d of cold storage.Proline and PAs in peach under chilling stress weremostly synthesized from glutamate and arginine,which were catalyzed by1-pyrroline-5-carboxylate synthetase and arginine decarboxylase,respectively.1-MCPtreated fruit exhibited higher proline and PA contents and enhanced chilling tolerance compared to the control,while ethylene-treated fruit had lower proline and PA contents and reduced chilling tolerance.Ethylene-treated fruit,which exhibited more severe CI symptoms compared to the control,had significantly(P<0.05)lower NO contents and NO synthase activities.However,NOmay not be a direct acting factor in 1-MCPinduced chilling tolerance,as 1-MCP-treated fruit had lower NO contents and NO synthase activities compared to the control.In conclusion,proline and PA clearly played direct and important roles in 1-MCP-induced peach chilling tolerance,while NO may not be actively involved. | Chunlu Qian Zhengjie Ji Qin Zhu Xiaohua Qi Qianqian Li Jiandong Yin Jun Liu Juan Kan Man Zhang Changhai Jin Lixia Xiao | 2021 | Horticultural Plant Journal2021，7，3： | 4 |
| 7 | Evaluation of Molecular Structural Effects on Needle Coke Mesophase Stacking显示文摘Molecular simulations were performed to investigate the molecular structural effects on needle coke mesophase stacking.The simulation results showed that the stacking states of anthracene trimer and tetramer accumulations were orderly,while the stacking states of anthracene dimer,pentamer,and hexamer accumulations were disorderly.Anthracene trimer and tetramer in the model compounds were two of the most ideal needle coke mesophase constituents.It was also found that the introduction of methyl side chains in anthracene trimer derivatives was not conducive to the formation of a mesophase crystal.To sum up,the molecules which had similar structures to anthracene trimer or tetramer with no alkyl chains are ideal constituents of needle coke mesophase. | Yang Haiyang Wang Chunlu Zhou Han Wang Lixin Ren Qiang Fan Qiming | 2020 | China Petroleum Processing & Petrochemical Technology2020，22，3： | 3 |
| 8 | An approximate analytic model for flow through capillary tubes显示文摘An analytic model for working fluids flowing through capillary tubes has been established with the approximate integral method. All the possible flow regimes in the capillary tubes,including subcooled, two-phase and superheated regimes, are covered in the model, and different analytic solutions are given respectively for each flow regime. As examples, the mass flow rates of refrigerants R12, R134a and R600a through capillary tubes are predicted by the model,and compared with those evaluated by a general distributed-parameter model. The mean bias falls into 1% and the maximum bias is 2.2%, while the computation speed of the new model is more than one order of magnitude higher than that of the distributed-parameter one. | Guoliang Ding Chunlu Zhang Hao Li Zhijiu Chen | 1999 | Chinese Science Bulletin1999，44，7： | 3 |
| 9 | Quantum Chemistry of PAHs Thermal Cracking with Different Hydrogenation Degree显示文摘In order to investigate the influence of hydrogenation degree and structural variety on reaction trend of polyaro- matic hydrocarbons (PAHs) in resins and asphaltenes portion of heavy oil, a series of PAHs with different hydrogenation degree were selected as model compounds to simulate their different hydrogenation stage, and the PAHs thermal cracking reaction was simulated based on free radical mechanism by the density functional theory (DFT) to search for reactions'transition state. By comparing the dynamic data obtained from reaction simulation, it is showed that processing difficulty could rise with increasing condensed aromatic ring number, and hydrogenation could promote ring cleavage reaction, but excessive hydrogenation would decrease the oil conversion rate to reduce light-end products. In conclusion, proper hydrogenation was quite critical in promoting light-end products conversion efficiency and saving the processing cost as well. Operational instructions were given based on both PAHs hydrogenation performance and conclusions were drawn up from reaction simulation results. | Wang Chunlu Zhou Han Dai Zhenyu Zhao Xiaoguang Zhao Yi | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，2： | 2 |
| 10 | DIV: Dynamic Integrity Validation Framework for Detecting Compromises on Virtual Machine Based Cloud Services in Real Time显示文摘with the increasing popularity of cloud services,attacks on the cloud infrastructure also increase dramatically.Especially,how to monitor the integrity of cloud execution environments is still a difficult task.In this paper,a real-time dynamic integrity validation(DIV) framework is proposed to monitor the integrity of virtual machine based execution environments in the cloud.DIV can detect the integrity of the whole architecture stack from the cloud servers up to the VM OS by extending the current trusted chain into virtual machine's architecture stack.DIV introduces a trusted third party(TTP) to collect the integrity information and detect remotely the integrity violations on VMs periodically to avoid the heavy involvement of cloud tenants and unnecessary information leakage of the cloud providers.To evaluate the effectiveness and efficiency of DIV framework,a prototype on KVM/QEMU is implemented,and extensive analysis and experimental evaluation are performed.Experimental results show that the DIV can efficiently validate the integrity of files and loaded programs in real-time,with minor performance overhead. | WANG Chunlu LIU Chuanyi LIU Bin DONG Yingfei | 2014 | China Communications2014，11，8： | 2 |
