| 1 | An Investigation of Optimal Machine Learning Methods for the Prediction of ROTI显示文摘The rate of the total electron content(TEC)change index(ROTI)can be regarded as an effective indicator of the level of ionospheric scintillation,in particular in low and high latitude regions.An accurate prediction of the ROTI is essential to reduce the impact of the ionospheric scintillation on earth observation systems,such as the global navigation satellite systems.However,it is difficult to predict the ROTI with high accuracy because of the complexity of the ionosphere.In this study,advanced machine learning methods have been investigated for ROTI prediction over a station at high-latitude in Canada.These methods are used to predict the ROTI in the next 5 minutes using the data derived from the past 15 minutes at the same location.Experimental results show that the method of the bidirectional gated recurrent unit network(BGRU)outperforms the other six approaches tested in the research.It is also confirmed that the RMSEs of the predicted ROTI using the BGRU method in all four seasons of 2017 are less than 0.05 TECU/min.It is demonstrated that the BGRU method exhibits a high level of robustness in dealing with abrupt solar activities. | Fulong XU Zishen LI Kefei ZHANG Ningbo WANG Suqin WU Andong HU Lucas Holden | 2020 | Journal of Geodesy and Geoinformation Science2020，3，2： | 7 |

| 3 | Realization of an Optimal Dynamic Geodetic Reference Frame in China:Methodology and Applications显示文摘China Geodetic Coordinate System 2000(CGCS2000)has been used for several years as a formal published reference frame.The coordinates of all global navigation satellite system(GNSS)stations in China need to be corrected to align with the CGCS2000 frame.Different strategies can be adopted for the realization of an optimal reference frame.However,different strategies lead to different results,with differences as great as several decimeters when GNSS station coordinates are transformed into CGCS2000-defined coordinates.The two common methods for the coordinate correction of a GNSS station are quasi-stable adjustment under CGCS2000 and plate movement correction,and the differences between their results can be greater than 10 cm.In this study,a statistic method called'supervised clustering'is applied to the selection of GNSS reference stations;a new scheme named'partition spacing'for the grouping of all processed GNSS stations is proposed;and the plate movement correction method is used to correct the coordinates of all GNSS stations from the GNSS epoch to the CGCS2000 epoch.The results from the new partitioning method were found to be significantly better than those from the conventional station-blocking approach.When coordinates from the stations without grouping were used as the standard,the accuracy of all the three-dimensional coordinate components from the new partitioning method was better than 2 mm.The root mean squares(RMSs)of the velocities in the x,y,and z directions resulting from the supervised clustering method were 0.19,0.45,and 0.32 mm∙a1,respectively,which were much smaller than the values of 0.92,0.72,and 0.97 mm∙a1 that resulted from the conventional approach.In addition,singular spectrum analysis(SSA)was used to model and predict the position nonlinear movements.The modeling accuracies of SSA were better than 3,2,and 5 mm in the east(E),north(N),and up(U)directions,respectively;and its prediction accuracies were better than 5 mm and 1 cm for the horizontal and vertical domains,respectively. | Pengfei Cheng Yingyan Cheng Xiaoming Wang Suqin Wu Yantian Xu | 2020 | Engineering2020，6，8： | 5 |
| 4 | Vertical characteristics and source identification of PM_(10) in Tianjin显示文摘Ambient PM 10 (particulate matter with a diameter less than 10μm) concentrations were measured on a 255 meter tower in Tianjin,China.The samples were collected at four vertical levels (10,40,120 and 220 m).Vertical characteristics for PM 10 samples were studied.The results showed that the concentrations of PM 10 and constituent species had a negative correlation with the sampling height.The highest concentrations of PM 10 and species were obtained at the 10 m level,and the lowest concentrations were measured at the 220 m level.For the fractions of species to total mass,SO 4 2- and NO 3- had higher values (fraction) at greater height;while Ca had a higher fraction at lower height.Possible source categories for the PM 10 ambient dataset were identified by the principal component analysis method.The possible source categories included crustal dust,vehicles,cement dust,and incineration as well as secondary sulfate and nitrate sources.Analysis of meteorological factors on PM 10 concentrations indicated that wind speed and inversion may be the main factors contributing to different concentrations of PM 10 at different heights. | Zhimei Xiao Jianhui Wu Suqin Han Yufen Zhang Hong Xu Xiaoyong Zhang Guoliang Shi Yinchang Feng | 2012 | Journal of Environmental Sciences2012，24，1： | 5 |

| 6 | Three-dimensional mesoscale eddy identification and tracking algorithm based on pressure anomalies Liming显示文摘The Kuroshio Extension(KE)is one of the most eddy-energetic regions in the global ocean.However,most mesoscale eddy studies in the region are focused on surface eddies and the structure and characteristics of three-dimensional(3-D)eddies require additional research.In this study,we proposed a 3-D eddy identification and tracking algorithm based on pressure anomalies,similar to sea level anomalies(SLAs)for surface eddy identification.We applied this scheme to a 5-year(2008-2012)high-resolution numerical product to develop a 3-D eddy dataset in the KE.The reliability of the numerical product was verified by the 5-year temperature/salinity hydrological characteristics and surface eddy distribution.According to the 3-D eddy tracking dataset,the number of eddies decreased dramatically as the eddy existence-time increased and more anticyclonic eddies(AEs)had an existence-time longer than 1 week than cyclonic eddies(CEs).We presented daily variations in the 3-D structure of two 3-D eddy-tracking trajectories that exhibit a certain jump in depth and a shift toward the west and equator.In addition to the bowl,lens,and cone eddies that have been discovered by previous researchers,we found that there is a cylindrical eddy,and its eddy radii are almost consistent across all layers.CEs cause significant negative temperature anomalies,“negative-positive”salinity anomalies,and sinking current fields in the KE region,while AEs cause positive temperature anomalies,“positive-negative”salinity anomalies,and upward current fields.The four types of eddies have different effects on the temperature/salinity anomalies and current field distribution which are related to their structure. | Liming YUAN Fenglin TIAN Suqin XU Chun ZHOU Jie CHEN | 2021 | Journal of Oceanology and Limnology2021，39，6： | 2 |
| 7 | Engineering Electronic Density and Coordination Environment of Mn–Nx Sites via Zn Cooperation for Quasi-Solid-State Zinc-Air Batteries显示文摘Due to the poor Fenton reactivity,single-atom Mn-based materials are generally identified as one of the most promising active catalysts for oxygen reduction reaction(ORR).Regulating the electronic density and coordination environment of atomically dispersed Mn centers is an effective strategy to enhance ORR activity of Mn-based materials.By introducing Zn sites,atomically dispersed Mn centers with multitudes of coordination(including Zn/Mn–Nx and Mn–Nx moieties)can be constructed to form Mn-based ORR catalyst(Zn/Mn-NC)with dual-atom sites.Around Mn–Nx sites,the Zn atoms can effectively modulate the electronic structure and coordination state of Mn centers in Zn/Mn-NC through d–d orbital coupling.The electronic interaction between Zn and Mn sites improves ORR activity,thereby optimizing the oxygen adsorption energy of Mn sites in Zn/Mn-NC and reducing the overall energy barrier.Zn/Mn-NC displays higher ORR half-wave potential than Pt/C(0.89 V vs 0.86 V).The quasi-solid-state zinc-air battery(ZAB)with Zn/Mn-NC as the cathode displayed excellent rechargeability,recyclability,and mechanical robustness.The strategy presented regulates the electronic density and coordination environment of singleatom Mn-based ORR catalysts in quasi-solid-state ZABs. | Daijie Deng Huixin Ma Suqin Wu Huan Wang Junchao Qian Jianchun Wu Huaming Li Cheng Yan Henan Li Li Xu | 2023 | Renewables2023，1，3： | 2 |

| 11 | Development of Transition Metal Nitrides as Oxygen and Hydrogen Electrocatalysts显示文摘With the increasing demand for energy, various emerging energy storage/conversion technologies have gradually penetrated human life, providing numerous conveniences. The practical application efficiency is often affected by the slow kinetics of hydrogen or oxygen electrocatalytic reactions(hydrogen evolution and oxidation reactions, oxygen evolution and reduction reactions) among the emerging devices. Therefore, the researchers devote to finding cost-effective electrocatalysts. Non-noble metal catalysts have low cost and good catalytic activity, but poor stability, agglomeration, dissolution, and other problems will occur after a long cycle, such as transition metal oxides and carbides. Transition metal nitrides(TMNs) stand out among all kinds of non-noble metal catalysts because of the intrinsic platinum-like electrocatalytic activities, relatively high conductivity, and wide range of tunability. In this review, the applications of TMNs in electrocatalytic fields are summarized based on the number of metals contained in TMNs. The practical application potentials of TMNs in fuel cell, water splitting, zinc-air battery and other electrochemical energy storage/conversion devices are also listed. Finally, the design strategies and viewpoints of TMNs-based electrocatalyst are summarized. The potential challenges of TMNs-based electrocatalyst in the development of electrocatalytic energy devices in the future are prospected. | Xuesheng Yan Daijie Deng Suqin Wu Henan Li Li Xu | 2022 | Chinese Journal of Structural Chemistry2022，41，7： | 1 |
