| 1 | CuFe2O4@GO nanocomposite as an effective and recoverable catalyst of peroxymonosulfate activation for degradation of aqueous dye pollutants显示文摘Recently,heterogeneous activation of peroxymonosulfate(PMS) to oxidatively degrade organic pollutants has been a hotspot.In the present work,copper ferrite-graphite oxide hybrid(CuFe2 O4@GO)was prepared and used as catalyst to activate PMS for degradation of methylene blue(MB) in aqueous solution.A high degradation efficiency(93.3%) was achieved at the experimental conditions of20 mg/L MB,200 mg/L CuFe2 O4@GO,0.8 mmol/L PMS,and 25℃temperature.Moreover,CuFe2 O4@GO showed an excellent reusability and stability.The effects of various operational parameters including pollutant type,solution pH,catalyst dosage,PMS dosage,pollutant concentration,temperature,natural organic matter(NOM),and inorganic anions on the catalytic degradation process were comprehensively investigated and elucidated.The further mechanistic study revealed the Cu(Ⅱ)/Cu(Ⅰ) redox couple on CuFe2 O4@GO played the dominant role in PMS activation,where both hydroxyl and sulfate radicals were generated and proceeded the degradation of pollutants.In general,CuFe2 O4@GO is a promising heterocatalyst for PMS-based advanced oxidation processes(AOPs) in wastewater treatment. | Xiaoman Lei Menghan You Fei Pan Min Liu Peng Yang Dongsheng Xia Qiang Li Yanting Wang Jie Fu | 2019 | Chinese Chemical Letters2019,30,12: | 8 |

| 3 | Refined chronology of prehistoric cultures and its implication for re-evaluating human-environment relations in the Hexi Corridor,northwest China显示文摘The reconstruction of high-resolution chronologies for prehistoric cultures is a prerequisite for understanding the history of human evolution and its relationship with environmental change, and is valuable for exploring the trajectory of transcontinental cultural exchanges in prehistoric time. The Hexi Corridor of northwest China was one of the earliest centers for long-distance culture exchange in the prehistoric world. The timing and sequence of cultural changes in this area remains poorly understood resulting from the lack of radiometric age control. This paper presents a refined radiocarbon(14 C) chronology to resolve the timing of human occupation and cultural evolution in the Hexi Corridor. Radiocarbon dating of crop remains, which have an annual life cycle, has the advantage of eliminating problems such as the carbon stored in ‘old wood’. As a result,14C dates from crop remains are used to test the validity of the14C dates derived from charcoal, bone and plant remains. The resultant database of ages is modelled using the Bayesian approach. The updated chronology presented in this paper shows generally good agreement with the original dates used to constrain cultural evolution in the Hexi Corridor. However, the occupation of the corridor by the Shajing and Shanma Late Bronze Age-Early Iron Age cultures appears to have taken place ~300 years later than previously thought. On the basis of comparing this updated chronology of cultural evolution with palaeoclimatic and historical records, it is proposed that the collapse of the Shajing and Shanma cultures occurred as a result of geopolitical impact rather than climate change. | Yishi YANG Shanjia ZHANG Chris OLDKNOW Menghan QIU Tingting CHEN Haiming LI Yifu CUI Lele REN Guoke CHEN Hui WANG Guanghui DONG | 2019 | Science China Earth Sciences2019,62,10: | 5 |
| 4 | In vitro immunomodulation of magnesium on monocytic cell toward anti-inflammatory macrophages显示文摘Biodegradable magnesium(Mg)has shown great potential advantages over current bone fixation devices and vascular scaffold technologies;however,there are few reports on the immunomodulation of corrosive Mg products,the micron-sized Mg particles(MgMPs).Human monocytic leukemia cell line THP-1 was set as the in vitro cell model to estimate the immunomodulation of MgMPs on cell proliferation,apoptosis,polarization and inflammatory reaction.Our results indicated highconcentration of Mg^2+ demoted the proliferation of the THP-1 cells and,especially,THP-1-derived macrophages,which was a potential factor that could affect cell function,but meanwhile,cell apoptosis was almost not affected by Mg^2+.In particular,the inflammation regulatory effects of MgMPs were investigated.Macrophages exposed to Mg^2+ exhibited down-regulated expressions of M1 subtype markers and secretions of pro-inflammatory cytokines,up-regulated expression of M2 subtype marker and secretion of anti-inflammatory cytokine.These results indicated Mg^2+ could convert macrophages from M0 to M2 phenotype,and the bioeffects of MgMPs on human inflammatory cells were most likely due to the Mg^2+-induced NF-jB activation reduction.Together,our results proved Mg^2+ could be used as a new anti-inflammatory agent to suppress inflammation in clinical applications,which may provide new ideas for studying the immunomodulation of Mg-based implants on human immune system. | Lei Sun Xiaoyu Li Menghan Xu Fenghe Yang Wei Wang Xufeng Niu | 2020 | Regenerative Biomaterials2020,7,4: | 3 |
| 5 | The regulatory network behind maize seed germination: Effects of temperature, water, phytohormones, and nutrients显示文摘Seed germination is the process by which an organism grows from a seed. It requires suitable conditions and environmental factors. Maize is one of the most important crops worldwide. Germination influences both final maize yield and quality. Seed germination is regulated by a complex gene network. It is also influenced by endogenous(phytohormones and nutrients) and exogenous(temperature and water)inputs, involving molecular networks only partly identified to date. This review describes current understanding of the influence of temperature, water, phytohormones, and nutrients in regulating maize seed germination, and indicates knowledge gaps that should be addressed. | Xiaofei Xue Shangyi Du Fuchao Jiao Menghan Xi Aiguo Wang Haicheng Xu Qiqing Jiao Xin Zhang Hao Jiang Jingtang Chen Ming Wang | 2021 | The Crop Journal2021,9,4: | 2 |

| 7 | Analysis and Optimization on Factors Affecting Forming Quality of Half Axle Gears Warm Precision Forging显示文摘Half axle gears is produced by precision forging popularly because of the advantages in minimum machining allowances, lower material consumption and good service properties. But the forming quality of precision forging is difficult to control. Many simulations and analysis of precision forging process were taken by previous researchers. But no concrete method is proposed to evaluate and optimize the forming quality of half axel gears. The primary purpose of this work is improving the forming quality of half axel gears by analyzing and optimizing the affected factors of forming quality. The enclosed-die warm forging process of half axle gears was developed, and a new type of die-set used on double action hydraulic press was brought forward. The main influential factors of precision forming quality were analyzed after the forming process had been simulated by using finite element method(FEM). These factors include die structure, web thickness and web position. A method used to evaluate the forming quality was established, which investigated the maximal forming load, the metal filling rate and the material damage factor. The FEM simulations of half axle gears precision forging were evaluated by this method. The results show that the best forming quality can be achieved when the punches were added with bosses, the web located at the middle plant of the gear, and the web thickness was 30 percent of the inner hole diameter. Verification experiments taking the above optimized parameters were performed on a 7.8 MN double action hydraulic press. The trial products were formed well. And their geometric precision meets the demand. The verification result shows that the optimization of the influential factors, according to the simulations and the evaluation method, can improve the forming quality. The new structure of precision forging die-set and the new evaluation method guarantee a high forming quality of half axel gears. | WANG Menghan CHEN Xihou ZHOU Jie | 2010 | Chinese Journal of Mechanical Engineering2010,23,1: | 2 |

| 9 | Resource Allocation Based on DEA and Non-Cooperative Game显示文摘Resource allocation is one of the most important applications of data envelopment analysis(DEA).Usually,the resource to be allocated is directly related to the interests of decision-making units(DMUs),thus the dynamic non-cooperative game is one of the representative behaviours in the allocation process.However,it is rarely considered in the previous DEA-based allocation studies,which may reduce the acceptability of the allocation plan.Therefore,this paper proposes a DEA-based resource allocation method considering the dynamic non-cooperative game behaviours of DMUs.The authors first deduce the efficient allocation set under the framework of variable return to scale(VRS)and build the allocation model subjecting to the allocation set.Then an iteration algorithm based on the concept of the non-cooperative game is provided for generating the optimal allocation plan.Several interesting characteristics of the algorithm are proved,including i)the algorithm is convergent,ii)the optimal allocation plan is a unique Nash equilibrium point,and iii)the optimal allocation plan is unique no matter which positive value the initial allocation takes.Some advantages of the allocation plan have been found.For example,the allocation plan is more balanced,has more incentives and less outliers,compared with other DEA-based allocation plans.Finally,the proposed method is applied to allocate the green credit among the 30 Chinese iron and steel enterprises,and the results highlight the applicability of the allocation method and solution approach.Therefore,the approach can provide decision makers with a useful resource allocation tool from the perspective of dynamic non-cooperative game. | WANG Menghan LI Lin DAI Qianzhi SHI Fangnan | 2021 | Journal of Systems Science & Complexity2021,34,6: | 1 |

| 12 | Quantitative analysis of work hardening and dynamic softening behaviors of Cu-6 wt pct Ag binary alloy based on true stress vs strain curves显示文摘The work hardening and dynamic softening behaviors of Cu-6 wt pct Ag binary alloy were studied by hot compression tests under temperature range of 700-850℃ at strain rates of 0.01-10s-1.The critical conditions for the onset of dynamic recrystallization (DRX) were determined based on the conventional strain hardening rate curves (dσ/dε versus σ).The progress of DRX was analyzed by constructing a model of volume fraction of DRX based on flow curves.The strain rate sensitivity (SRS) and activation volume V were calculated.The results show that the DRX almost can happen under all deformation conditions even at high Z deformations where dynamic recovery (DRV) is the main softening mechanism.The DRX fraction curves can well predict the DRX behavior.The strain has significant effects on SRS at the strain rates of 0.01s-1 and 10s-1 which are mainly due to off-equilibrium saturation of dislocation storage and annihilation while the effects of the temperature on the SRS are based on the uniformity of microstructure distribution.The formation of 'forest' of dislocation is contributed to the low activation volume V*(about 168b3) which is independent of Z values at the initial deformation.The cross-slip due to dislocation piled up beyond the grain boundaries or obstacles is related to the low activation volume under the high Z deformation conditions at high strain (ε=0.6) while the fine DRX grains coarsed is the main reason for the high activation volume at low Z under the same strain conditions. | Menghan WANG Wenhao WANG Jingjing DONG Linhui ZHANG Yunping LI Akihiko CHIBA | 2012 | Acta Metallurgica Sinica(English Letters)2012,25,6: | 1 |

| 14 | A dynamic ejection coal burst model for coalmine roadway collapse显示文摘In this study,we established a dynamic ejection coal burst model for a coalmine roadway subject to stress,and held that the stress concentration zone at the roadway side is the direct energy source of this ejection.The formation and development of such burst undergoes three stages:(1)instability and propagation of the cracks in the stress concentration zone,(2)emerging of a layered energy storage structure in the zone,and(3)ejection of coal mass or coal burst due to instability.Moreover,we figured out the initial strength of periodic cracks is parallel to the maximal dominant stress direction in the stress concentration zone and derived from the damage strain energy within the finite area of the zone based on the Griffith energy theory.In addition,we analyzed the formation process of the layered energy storage structure in the zone,simplified it as a simply supported restraint sheet,and calculated the minimum critical load and the internally accumulated elastic energy at the instable state.Furthermore,we established a criterion for occurrence of the coal burst based on the variational principle,and analyzed the coal mass ejection due to instability and coal burst induced by different intensity disturbances.At last,with the stratum conditions of Junde Coalmine as the model prototype,we numerically simulated the load displacement distribution of the stress concentration zone ahead of the working face disturbed by the main roof-fracture-induced dynamic load during the mining process as well as their varying characteristics,and qualitatively verified the above model. | Dazhao Song Xueqiu He Enyuan Wang Zhenlei Li Menghan Wei Hongwei Mu | 2019 | International Journal of Mining Science and Technology2019,29,4: | 1 |

| 17 | PCA-U-Net based breast cancer nest segmentation from microarray(jj)hyperspectral images显示文摘The incidence of breast cancer is tending younger globally,and tumor development,clinical treatment,and prognosis are largely influenced by histopathological diagnosis.For diagnosed patients,the distinction between the cancer nests and normal tissue is the basis of breast cancer treatment.Microscopic hyperspectral imaging technology has shown its potential in auxiliary pathological examinations due to the superior imaging modality and data characteristics.This paper presents a method for cancer nest segmentation from hyperspectral images of breast cancer tissue microarray samples.The scheme combines the strengths of the U-Net neural network and unsupervised principal component analysis,which reduces the amount of calculation and improves the recognition accuracy.The experimental accuracy of cancer nest segmentation reaches 87.14%.Furthermore,a set of quantitative pathological characteristic parameters reflects the degree of breast cancer lesions from multiple angles,providing a relatively comprehensive reference for the pathologist’s diagnosis.In-depth exploration of the combined development of deep learning and microscopic hyperspectral imaging technology is worthy to promote efficient diagnosis of breast tumors and concern for human health. | Jiansheng Wang Yan Wang Xiang Tao Qingli Li Li Sun Jiangang Chen Mei Zhou Menghan Hu Xiufeng Zhou | 2021 | Fundamental Research2021,1,5: | 1 |
| 18 | Tolerance Granulation Based Community Detection Algorithm显示文摘Community structure is one of the most important features in real networks and reveals the internal organization of the vertices. Uncovering accurate community structure is effective for understanding and exploiting networks. Tolerance Granulation based Community Detection Algorithm(TGCDA) is proposed in this paper, which uses tolerance relation(namely tolerance granulation) to granulate a network hierarchically. Firstly, TGCDA relies on the tolerance relation among vertices to form an initial granule set. Then granules in this set which satisfied granulation coefficient are hierarchically merged by tolerance granulation operation. The process is finished till the granule set includes one granule. Finally, select a granule set with maximum granulation criterion to handle overlapping vertices among some granules. The overlapping vertices are merged into corresponding granules based on their degrees of affiliation to realize the community partition of complex networks. The final granules are regarded as communities so that the granulation for a network is actually the community partition of the network.Experiments on several datasets show our algorithm is effective and it can identify the community structure more accurately. On real world networks, TGCDA achieves Normalized Mutual Information(NMI) accuracy 17.55% higher than NFA averagely and on synthetic random networks, the NMI accuracy is also improved. For some networks which have a clear community structure, TGCDA is more effective and can detect more accurate community structure than other algorithms. | Shu Zhao Wang Ke Jie Chen Feng Liu Menghan Huang Yanping Zhang Jie Tang | 2015 | Tsinghua Science and Technology2015,20,6: | 1 |

| 20 | Optimization of Process Parameters for Cracking Prevention of UHSS in Hot Stamping Based on Hammersley Sequence Sampling and Back Propagation Neural Network-Genetic Algorithm Mixed Methods显示文摘In order to prevent cracking appeared in the work-piece during the hot stamping operation,this paper proposes a hybrid optimization method based on Hammersley sequence sampling( HSS),finite analysis,backpropagation( BP) neural network and genetic algorithm( GA). The mechanical properties of high strength boron steel are characterized on the basis of uniaxial tensile test at elevated temperatures. The samples of process parameters are chosen via the HSS that encourages the exploration throughout the design space and hence achieves better discovery of possible global optimum in the solution space. Meanwhile, numerical simulation is carried out to predict the forming quality for the optimized design. A BP neural network model is developed to obtain the mathematical relationship between optimization goal and design variables,and genetic algorithm is used to optimize the process parameters. Finally,the results of numerical simulation are compared with those of production experiment to demonstrate that the optimization strategy proposed in the paper is feasible. | menghan wang zongmin yue lie meng | 2016 | Journal of Harbin Institute of Technology(New Series)2016,23,2: | 1 |
