| 1 | A Brief Review of Network Embedding显示文摘Learning the representations of nodes in a network can benefit various analysis tasks such as node classification, link prediction, clustering, and anomaly detection. Such a representation learning problem is referred to as network embedding, and it has attracted significant attention in recent years. In this article, we briefly review the existing network embedding methods by two taxonomies. The technical taxonomy focuses on the specific techniques used and divides the existing network embedding methods into two stages, i.e., context construction and objective design. The non-technical taxonomy focuses on the problem setting aspect and categorizes existing work based on whether to preserve special network properties, to consider special network types, or to incorporate additional inputs. Finally, we summarize the main findings based on the two taxonomies, analyze their usefulness,and discuss future directions in this area. | Yaojing Wang Yuan Yao Hanghang Tong Feng Xu Jian Lu | 2019 | Big Data Mining and Analytics2019，2，1： | 3 |
| 2 | Impact of estuarine reclamation projects on saltwater intrusion and freshwater resource显示文摘Estuarine projects can change local topography and influence water transport and saltwater intrusion.The Changjiang(Yangtze)River estuary is a multichannel estuary,and four major reclamation projects have been implemented in the Changjiang River estuary in recent years:the Xincun Shoal reclamation project(RP-XCS),the Qingcao Shoal reclamation project(RP-QCS),the Eastern Hengsha Shoal reclamation project(RP-EHS),and the Nanhui Shoal reclamation project(RP-NHS).The effects of the four reclamation projects and each project on the saltwater intrusion and water resources in the Changjiang River estuary were simulated in a 3D numerical model.Results show that for a multichannel estuary,local reclamation projects change the local topography and water diversion ratio(WDR)between channels and influence water and salt transport and freshwater utilization in the estuary.During spring tide,under the cumulative effect of the four reclamation projects,the salinity decreases by approximately 0.5in the upper reaches of the North Branch and increases by 0.5-1.0 in the middle and lower reaches of the North Branch.In the North Channel,the salinity decreases by approximately 0.5.In the North Passage,the salinity increases by 0.5-1.0.In the South Passage,the salinity increases by approximately 0.5 in the upper reaches and decreases by 0.2-0.5 on the north side of the middle and lower reaches.During neap tide,the cumulative effects of the four reclamation projects and the individual projects are similar to those during spring tide,but there are some differences.The effects of an individual reclamation project on WDR and saltwater intrusion during spring and neap tides are simulated and analyzed in detail.The cumulative effect of the four reclamation projects favors freshwater usage in the Changjiang River estuary. | Hanghang LU Jianrong ZHU Qing CHEN Ming LI Shunqi PAN Shenliang CHEN | 2023 | Journal of Oceanology and Limnology2023，41，1： | 1 |
| 3 | Stabilization of Cd and Pb in the contaminated soils by applying modified fly ash显示文摘This study investigated the stabilization of heavy metals by adding modified fly ash(FA)to contaminated soils,and two similar materials,NaOH-zeolite(ZE)and natural zeolite(ZO)were introduced into the soils for comparison.Column leaching tests were conducted to analyze the difference of stabilization effects between the three materials.Leaching columns were run for 6 months,and a considerable stabilization of heavy metals in the soils was observed.The concentration of cadmium(Cd)and lead(Pb)in the amended soil substantially decreased(p<0.05).The results indicated that after 11 weeks of column leaching,Cd and Pb concentrations in the soil leachate decreased to below the detection limit due to amendment stabilization.Among the three amendments,the ZE amendment showed the optimum capacity for heavy metal immobilisation in the soils.In addition,after 6 months of leaching,Pb and Cd concentrations in the soils with the three different amendments decreased to various degrees.The amendments of modified FA and ZE were better than those of natural ZO.Coal FA,after modification,is a useful amendment for the remediation of heavy metals in the contaminated soil. | Fuhao Liu Xunrong Huang Hanghang Zhao Xiongfei Hu Lu Wang Xin Zhao Pengcheng Gao Puhui Ji | 2021 | Soil Ecology Letters2021，3，3： | 0 |
