| 1 | Methods of rapid orbit forecasting after maneuvers for geostationary satellites显示文摘A geostationary(GEO) satellite may serve as a navigation satellite,but there is a problem that maneuvers frequently occur and the forces are difficult to model.Based on the technique of determining satellite orbits by transfer,a predicted orbit with high accuracy may be achieved by the method of statis-tical orbit determination in case of no maneuver force.The predicted orbit will soon be invalid after the maneuver starts,and it takes a long time to get a valid orbit after the maneuver ends.In order to improve ephemeris usability,the method of rapid orbit forecasting after maneuvers is studied.First,GEO satellite movement is analyzed in case of maneuvers based on the observation from the orbit meas-urement system by transfer.Then when a GEO satellite is in the free status just after maneuvers,the short arc observation is used to forecast the orbit.It is assumed that the common system bias and biases of each station are constant,which can be obtained from orbit determination with long arc observations.In this way,only 6 orbit elements would be solved by the method of statistical orbit determination,and the ephemeris with high accuracy may be soon obtained.Actual orbit forecasting with short arc observation for SINOSAT-1 satellite shows that,with the tracking network available,the precision of the predicted orbit(RMS of O-C) can reach about 5 m with 15 min arc observation,and about 3 m with 30 min arc observation. | YANG XuHai LI ZhiGang FENG ChuGang GUO Ji SHI HuLi AI GuoXiang WU FengLei QIAO RongChuan | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，3： | 10 |
| 2 | Health-related quality of life among rural residents aged 45-69 years in Hua County, Henan Province, China: Results of ESECC Trial for esophageal cancer screening with endoscopy显示文摘Objective: There have been few population-based studies evaluating health related quality of life(HRQOL) in rural populations in China, and this study aimed to assess the current status of and risk factors for HRQOL in a general rural population in high risk region of esophageal cancer in China.Methods: From November 2015 to September 2016, 12,085 permanent residents aged 45–69 years from 257 villages in the Endoscopic Screening for Esophageal Cancer in China(ESECC) trial(Clinical Trials.gov:NCT01688908) randomly selected from Hua County, Henan Province, China were interviewed. The EQ-5 D-3 L,a generic measure of HRQOL, and a questionnaire were used to assess their HRQOL and potential risk factors.Results: Among all the participants, 30.62% of the participants reported problems in at least one EQ-5 D dimension. Pain/discomfort(25.52%) was the most frequently reported problem followed by anxiety/depression(7.97%), mobility(5.82%), usual activities(2.61%) and self-care(1%). These rural residents had a mean EQ-5 D index score of 0.948, and lower EQ-5 D index scores were associated with older age, female gender, lower levels of household annual per capita income, living alone, using shallow wells as main source of drinking water, exposure to family members smoking, testiness, unhealthy dietary habits, overweight or obesity, upper gastrointestinal cancer related symptoms and chronic diseases.Conclusions: Rural residents in China have a relatively low quality of life. Health promotion programs in this population should focus on the elderly, especially elderly women and the elderly living alone. Improving basic living circumstances and primary medical care services should be priorities. Results of this study will also serve as the basis for the cost-utility evaluation in our ESECC screening trial. | Hui Wang Yaqi Pan Chuanhai Guo Fenglei Li Ruiping Xu Mengfei Liu Zhen Liu Fangfang Liu Hong Cai Yang Ke Zhonghu He | 2018 | Chinese Journal of Cancer Research2018，30，2： | 3 |
| 3 | Oral microbiome and risk of malignant esophageal lesions in a high-risk area of China:A nested case-control study显示文摘Objective:We aimed to prospectively evaluate the association of oral microbiome with malignant esophageal lesions and its predictive potential as a biomarker of risk.Methods:We conducted a case-control study nested within a population-based cohort with up to 8 visits of oral swab collection for each subject over an 11-year period in a high-risk area for esophageal cancer in China.The oral microbiome was evaluated with 16 S ribosomal RNA(rRNA)gene sequencing in 428 pre-diagnostic oral specimens from 84 cases with esophageal lesions of severe squamous dysplasia and above(SDA)and 168 matched healthy controls.DESeq analysis was performed to identify taxa of differential abundance.Differential oral species together with subject characteristics were evaluated for their potential in predicting SDA risk by constructing conditional logistic regression models.Results:A total of 125 taxa including 37 named species showed significantly different abundance between SDA cases and controls(all P<0.05&false discovery rate-adjusted Q<0.10).A multivariate logistic model including 11 SDA lesion-related species and family history of esophageal cancer provided an area under the receiver operating characteristic curve(AUC)of 0.89(95%CI,0.84-0.93).Cross-validation and sensitivity analysis,excluding cases diagnosed within 1 year of collection of the baseline specimen and their matched controls,or restriction to screenendoscopic-detected or clinically diagnosed case-control triads,or using only bacterial data measured at the baseline,yielded AUCs>0.84.Conclusions:The oral microbiome may play an etiological and predictive role in esophageal cancer,and it holds promise as a non-invasive early warning biomarker for risk stratification for esophageal cancer screening programs. | Fangfang Liu Mengfei Liu Ying Liu Chuanhai Guo Yunlai Zhou Fenglei Li Ruiping Xu Zhen Liu Qiuju Deng Xiang Li Chaoting Zhang Yaqi Pan Tao Ning Xiao Dong Zhe Hu Huanyu Bao Hong Cai Isabel Dos Santos Silva Zhonghu He Yang Ke | 2020 | Chinese Journal of Cancer Research2020，32，6： | 3 |
| 4 | Identification of cancer patients using claims data from health insurance systems: A real-world comparative study显示文摘Objective: To evaluate the accuracy of identifying cancer patients by use of medical claims data in a health insurance system in China, and provide the basis for establishing the claims-based cancer surveillance system in China.Methods: We chose Hua County, Henan Province as the study site, and randomly selected 300 and 1,200 qualified inpatient electronic medical records(EMRs) as well as the New Rural Cooperative Medical Scheme(NCMS) claims records for cancer patients in Hua County People’s Hospital(HCPH) and Anyang Cancer Hospital(ACH) in 2017. Diagnostic information for NCMS claims was evaluated on an individual level, and sensitivity and positive predictive value(PPV) were calculated taking the EMRs as the gold standard.Results: The sensitivity of NCMS was 95.2%(93.8%-96.3%) and 92.0%(88.3%-94.8%) in ACH and HCPH,respectively. The PPV of the NCMS was 97.8%(96.7%-98.5%) in ACH and 89.0%(84.9%-92.3%) in HCPH.Overall, the weighted and combined sensitivity and PPV of NCMS in Hua County was 93.1% and 92.1%,respectively. Significantly higher sensitivity and PPV in identifying patients with common cancers than noncommon cancers were detected in HCPH and ACH separately(P<0.01).Conclusions: Identification of cancer patients by use of the NCMS is accurate on individual level, and it is therefore feasible to conduct claims-based cancer surveillance in areas not covered by cancer registries in China. | Hongrui Tian Ruiping Xu Fenglei Li Chuanhai Guo Lixin Zhang Zhen Liu Mengfei Liu Yaqi Pan Zhonghu He Yang Ke | 2019 | Chinese Journal of Cancer Research2019，31，4： | 3 |
| 5 | Biophysical studies of the interaction between a triazole derivative and bovine serum albumin by multi-spectroscopic and molecular modeling methods显示文摘The interaction between 3-thiol-4-(2,4-dichlorobenzylideneamino)-5-methyl-4H-1,2,4-triazole (CBTZ) and bovine serum albumin (BSA) under physiological conditions was investigated by fluorescence,UV-vis absorption and circular dichroism (CD) spectroscopy as well as molecular modeling methods. The result of fluorescence experiment indicates the static quenching as a result of the formation of the CBTZ-BSA complex. The binding constants (Ka) at different temperatures were calculated according to the modified Stern-Volmer equation. The enthalpy change (-H) and entropy change (-S) were determined based on the van′t Hoff equation. Both negative-H and-S indicated that van der Waals and hydrogen-bonding forces were the dominant intermolecular forces to stabilize the CBTZ-BSA complex. Site marker competitive replacement experiments demonstrated that binding of CBTZ to BSA primarily took place in sub-domain IIA (Sudlow's site I). The binding distance (r = 7.2 nm) between CBTZ and the tryptophan residue of BSA was estimated according to the theory of fluorescence resonance energy transfer (FRET). The conformational studies by circular dichroism (CD) and three-dimensional fluorescence spectroscopy showed that the presence of CBTZ induced minor changes of the secondary structure of BSA. Molecular modeling study further confirmed the binding mode obtained experimentally. | FU JiaXin WANG KaiWei GE YuShu JIANG FengLei SUN XiaoHong LIU Yang LIU Yi | 2011 | Science China Chemistry2011，54，5： | 2 |
| 6 | Atomically dispersed Co-Cu alloy reconstructed from metalorganic framework to promote electrochemical CO_(2)methanation显示文摘Electroreduction of carbon dioxide into value-added fuels or chemicals using renewable energy helps to effectively reduce carbon dioxide emission and alleviate the greenhouse effect while storing intermittent energies.Due to the existing infrastructure of global natural gas utilization and distribution,methane produced in such a green route attracts wide interests.However,limited success has been witnessed in the practical application of catalysts imparting satisfactory methane activity and selectivity.Herein,we report the fabrication of an atomically dispersed Co-Cu alloy through the reconstruction of trace-Co doped Cu metalorganic framework.This catalyst exhibits a methane Faradaic efficiency of 60%±1%with the corresponding partial current density of 303±5 mA·cm^(−2).Operando X-ray adsorption spectroscopy and attenuated-total-reflection surface enhanced infrared spectroscopy unravel that the introduction of atomically dispersed Co in Cu favors*CO protonation via enhancing surface water activation,and suppresses C−C coupling by reducing*CO coverage,thereby leading to high methane selectivity. | Hao Sun Ling Lin Wei Hua Xulan Xie Qiaoqiao Mu Kun Feng Jun Zhong Fenglei Lyu Zhao Deng Yang Peng | 2023 | Nano Research2023，16，3： | 1 |

| 9 | Recovery of Ni(Ⅱ)from real electroplating wastewater using fixed-bed resin adsorption and subsequent electrodeposition显示文摘Effective recovery of high-value heavy metals from electroplating wastewater is of great significance,but recovering nickel ions from real electroplating wastewater as nickel sheet has not been reported.In this study,the pilot-scale fixed-bed resin adsorption was conducted to recover Ni(Ⅱ)ions from real nickel plating wastewater,and then the concentrated Ni(Ⅱ)ions in the regenerated solution were reduced to nickel sheet via electrodeposition.A commercial cation-exchange resin was selected and the optimal resin adsorption and regeneration conditions were investigated.The resin exhibited an adsorption capacity of 63 mg/g for Ni(Ⅱ)ions,and the average amount of treated water was 84.6 bed volumes(BV)in the pilot-scale experiments.After the adsorption by two ion-exchange resin columns in series and one chelating resin column,the concentrations of Ni(Ⅱ)in the treated wastewater were below 0.1 mg/L.After the regeneration of the spent resin using 3 BVof 4%(w/w)HC1 solution,1.5 BV of concentrated neutral nickel solution(>30 g/L)was obtained and used in the subsequent electrodeposition process.Using the aeration method,alkali and water required in resin activation process were greatly reduced to 2 BV and 3 BV,respectively.Under the optimal electrodeposition conditions,95.6%of Ni(Ⅱ)in desorption eluent could be recovered as the elemental nickel on the cathode,llie total treatment cost for the resin adsorption and regeneration as well as the electrodeposition was calculated. | Tong Li Ke Xiao Bo Yang Guilong Peng Fenglei Liu Liyan Tao Siyuan Chen Haoran Wei Gang Yu Shubo Deng | 2019 | Frontiers of Environmental Science & Engineering2019，13，6： | 1 |

| 12 | Data Matching of Solar Images Super-Resolution Based on Deep Learning显示文摘The images captured by different observation station have different resolutions.The Helioseismic and Magnetic Imager(HMI:a part of the NASA Solar Dynamics Observatory SDO)has low-precision but wide coverage.And the Goode Solar Telescope(GST,formerly known as the New Solar Telescope)at Big Bear Solar Observatory(BBSO)solar images has high precision but small coverage.The super-resolution can make the captured images become clearer,so it is wildly used in solar image processing.The traditional super-resolution methods,such as interpolation,often use single image’s feature to improve the image’s quality.The methods based on deep learning-based super-resolution image reconstruction algorithms have better quality,but small-scale features often become ambiguous.To solve this problem,a transitional amplification network structure is proposed.The network can use the two types images relationship to make the images clear.By adding a transition image with almost no difference between the source image and the target image,the transitional amplification training procedure includes three parts:transition image acquisition,transition network training with source images and transition images,and amplification network training with transition images and target images.In addition,the traditional evaluation indicators based on structural similarity(SSIM)and peak signal-to-noise ratio(PSNR)calculate the difference in pixel values and perform poorly in cross-type image reconstruction.The method based on feature matching can effectively evaluate the similarity and clarity of features.The experimental results show that the quality index of the reconstructed image is consistent with the visual effect. | Liu Xiangchun Chen Zhan Song Wei Li Fenglei Yang Yanxing | 2021 | Computers, Materials & Continua2021，，9： | 0 |
| 13 | Electrochemical CO_(2) reduction catalyzed by organic/inorganic hybrids显示文摘Electroreduction of CO_(2) into value-added chemicals and fuels utilizing renewable electricity offers a sustainable way to meet the carbon-neutral goal and a viable solution for the storage of intermittent green energy sources.At the core of this technology is the development of electrocatalysts to accelerate the redox kinetics of CO_(2) reduction reactions(CO_(2)RR)toward high targeted-product yield at minimal energy input.This perspective focuses on a unique category of CO_(2)RR electrocatalysts embodying both inorganic and organic components to synergistically promote the reaction activity,selectivity and stability.First,we summarize recent progress on the design and fabrication of organic/inorganic hybrids CO_(2)RR electrocatalysts,with special attention to the assembly protocols and structural configurations.We then carry out a comprehensive discussion on the mechanistic understanding of CO_(2)RR processes tackled jointly by the inorganic and organic phases,with respect to the regulation of mass and charge transport,modification of double-layer configuration,tailoring of intermediates adsorption,and establishment of tandem pathways.At the end,we outline future challenges in the rational design of organic/inorganic hybrids for CO_(2)RR and further extend the scope to the device level.We hope this work could incentivize more research interests to construct organic/inorganic hybrids for mobilizing electrocatalytic CO_(2)RR towards industrialization. | Daqi Song Yuebin Lian Min Wang Yanhui Su Fenglei Lyu Zhao Deng Yang Peng | 2023 | eScience2023，3，2： | 0 |
| 14 | Electronic and Nano-structural Modulation of Co(OH)_(2) Nanosheets by Fe-Benzenedicarboxylate for Efficient Oxygen Evolution显示文摘Oxygen evolution reaction(OER)plays a key role in the electrochemical conversion and storage processes,but the sluggish kinetics of OER strongly impedes its large-scale applications.We herein reported the in situ growth of Fe-benzenedicarboxylate(Fe-BDC)on Co(OH)_(2) nanoplates[Fe-BDC/Co(OH)_(2)]that showed remarkably enhanced OER activity than the pristine Co(OH)_(2).The incorporation of Fe species could enhance the intrinsic OER activity of Co and BDC could increase the electrochemically active surface area(ECSA),thus resulting in dramatically enhanced OER activity.In situ Raman spectroscopy characterization disclosed that Fe-CoOOH reconstructed from Fe-BDC/Co(OH)_(2) was the real active site for OER.This work highlights the significance of rational tailoring of the nanostructure and electronic structure of Co(OH)_(2) and provides more opportunities for its widespread applications. | XIAO Long WU Huirong ZHANG Yong SUN Hao ZHANG Wenchao LYU Fenglei DENG Zhao PENG Yang | 2023 | Chemical Research in Chinese Universities2023，39，2： | 0 |
