| 1 | Investigation of phosphate adsorption from an aqueous solution using spent fluid catalytic cracking catalyst containing lanthanum显示文摘A spent fluid catalytic cracking (FCC)catalyst containing lanthanum (La)was used as a novel adsorbent for phosphorus (P)in simulated wastewater.The experiments were conducted in a batch system to optimize the operation variables,including pH,calcination temperature,shaking time,solidliquid ratio,and reaction temperature under three initial P-concentrations (C0=0.5,1.0,and 5.0mg/L). Orthogonal analysis was used to determine that the initial P-concentration was the most important parameter for P removal.The P-removal rate exceeded 99% and the spent FCC catalyst was more suitable for use in low P-concentration wastewater (C0<5.0mg/L).Isotherms,thermodynamics and dynamics of adsorption are used to analyze the mechanism of phosphorus removal.The results show that the adsorption is an endothennic reaction with high affinity and poor reversibility,which indicates a low risk of second releasing of phosphate.Moreover,chemical and physical adsorption coexist in this adsorption process with LAPO4 and KH2PO4formed on the spent FCC catalyst as the adsorption product.These results demonstrate that the spent FCC catalyst containing La is a potential adsorbent for P-removal from wastewater,which allows recycling of the spent FCC catalyst to improve the quality of water body. | Zhen Li Zhaofu Qiu Ji Yang Benteng Ma Shuguang Lu Chuanhui Qin | 2018 | Frontiers of Environmental Science & Engineering2018，12，6： | 2 |

| 5 | Spatiotemporal variations and driving factors of habitat quality in the loess hilly area of the Yellow River Basin:A case study of Lanzhou City,China显示文摘Rapid industrialization and urbanization have led to the most serious habitat degradation in China,especially in the loess hilly area of the Yellow River Basin,where the ecological environment is relatively fragile.The contradiction between economic development and ecological environment protection has aroused widespread concern.In this study,we used the habitat quality of Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST-HQ)model at different scales to evaluate the dynamic evolution characteristics of habitat quality in Lanzhou City,Gansu Province of China.The spatiotemporal variations of habitat quality were analyzed by spatial autocorrelation.A Geographical Detector(Geodetector)model was used to explore the driving factors that influencing the spatial differentiation of habitat quality,including natural factors,socio-economic factors,and ecological protection factors.The results showed that the habitat quality index of Lanzhou City decreased from 0.4638 to 0.4548 during 2000-2018.The areas with reduced the habitat quality index were mainly located in the Yellow River Basin and Qinwangchuan Basin,where are the main urban areas and the new economic development areas,respectively.The spatial distribution of habitat quality presented a trend of high in the surrounding areas and low in the middle,and showed a significant positive spatial autocorrelation.With the increase of study scale,the spatial distribution of habitat quality changed from concentrated to dispersed.The spatial differentiation of habitat quality in the study area was the result of multiple factors.Among them,topographic relief and slope were the key factors.The synergistic enhancement among these driving factors intensified the spatial differentiation of habitat quality.The findings of this study can provide a scientific basis for land resources utilization and ecosystem restoration in the arid and semi-arid land. | DONG Jianhong ZHANG Zhibin LIU Benteng ZHANG Xinhong ZHANG Wenbin CHEN Long | 2022 | Journal of Arid Land2022，14，6： | 1 |

| 17 | SOME INITIAL-OBLIQUE DERIVATIVE BOUNDARY VALUE PROBLEM FOR QUASILINEAR PARABOLIC EQUATIONS WITH UNBOUNDED COEFFICIENTS显示文摘In this paper, we consider quasilinear uniformly parabolic equations: Lu = aij (t, x, u)Diju + b(t, x u, Du) - ut = 0, with regular derivative boundary value problems: Bu = u/ v + au = h(t, x). By the help of Leray-schauder fixed point theorem, we get the a priori estimates and the existence theorem. | ZOU Benteng (School Of Mathematics Science, Peking University, Beijing 100871, China 15 MLH University Of Iowa, Iowa City, IA 52242-1419, USA) | 2001 | Journal of Systems Science & Complexity2001，14，3： | 0 |
| 18 | Characteristics of snow cover distribution along railway subgrade and the protective effect of snow fences显示文摘Railways built in cold,snowy,and lightly populated areas are subjected to wind and snow disasters.In this study,we selected a snow hazard prevention and control section of the Altay–Zhundong Railway in Xinjiang Uygur Autonomous Region of China as the research object.We investigated the deposited snowfall variation characteristics on the two sides and in the embankment pavement area of snow fences with different porosities,fence heights,and arrangement distances using single-factor tests and orthogonal tests based on global atmospheric reanalysis climate data,field survey data,and a multi-phase flow analysis model.The results showed significant differences in the characteristics of snow cover distribution and snow cover thickness between the embankment and the cutting in the absence of snow protection measures.The maximum snow cover thickness of the embankment pavement decreased by 12.6%relative to the cutting pavement.The snow cover thickness of the embankment exhibited an increasing trend from windward shoulder to leeward shoulder,whereas the snow cover thickness of the cutting presented a declining trend from windward shoulder to leeward toe.In the collaborative prevention and control of snow fences and embankments,the three factors can be ranked in terms of their sensitivity to deposited snowfall within the influence scope of snow fences as follows:fence height>arrangement distance>porosity.At the same time,fence height yielded a significant relationship for the influence scope of snow fences(P<0.05).The three factors can also be ranked in terms of their sensitivity to deposited snowfall on the pavement as follows:porosity>fence height>arrangement distance.For the embankment protection of the Altay–Zhundong Railway against wind and snow,snow fence with a porosity of 75%,a fence height of 4.8 m,and an arrangement distance from the embankment of 60 m produced the best snow control effect.By revealing the characteristics of snow cover distribution along railway subgrade and the protective effect of snow fences,this study provides valuable references for the engineering applications of railway construction in areas prone to wind and snow disasters. | LEI Jia CHENG Jianjun GAO Li MA Benteng AN Yuanfeng DONG Hongguang | 2023 | Journal of Arid Land2023，15，8： | 0 |
| 19 | Improving Federated Learning through Abnormal Client Detection and Incentive显示文摘Data sharing and privacy protection are made possible by federated learning,which allows for continuous model parameter sharing between several clients and a central server.Multiple reliable and high-quality clients must participate in practical applications for the federated learning global model to be accurate,but because the clients are independent,the central server cannot fully control their behavior.The central server has no way of knowing the correctness of the model parameters provided by each client in this round,so clients may purposefully or unwittingly submit anomalous data,leading to abnormal behavior,such as becoming malicious attackers or defective clients.To reduce their negative consequences,it is crucial to quickly detect these abnormalities and incentivize them.In this paper,we propose a Federated Learning framework for Detecting and Incentivizing Abnormal Clients(FL-DIAC)to accomplish efficient and security federated learning.We build a detector that introduces an auto-encoder for anomaly detection and use it to perform anomaly identification and prevent the involvement of abnormal clients,in particular for the anomaly client detection problem.Among them,before the model parameters are input to the detector,we propose a Fourier transform-based anomaly data detectionmethod for dimensionality reduction in order to reduce the computational complexity.Additionally,we create a credit scorebased incentive structure to encourage clients to participate in training in order tomake clients actively participate.Three training models(CNN,MLP,and ResNet-18)and three datasets(MNIST,Fashion MNIST,and CIFAR-10)have been used in experiments.According to theoretical analysis and experimental findings,the FL-DIAC is superior to other federated learning schemes of the same type in terms of effectiveness. | Hongle Guo Yingchi Mao Xiaoming He Benteng Zhang Tianfu Pang Ping Ping | 2024 | Computer Modeling in Engineering & Sciences2024，139，4： | 0 |
