| 1 | Super-resolution of geosynchronous synthetic aperture radar images using dialectical GANs显示文摘Dear editor,The concept of geosynchronous synthetic aperture radar (GEO SAR) system was conceived in an effort to realize a quick observation of emergency disasters (e.g., landslides and earthquakes)[1].The novel GEO SAR system has the significant advantages of short-revisit time and large coverage and facilitates the nearly continuous observation of target regions, unlike the currently operatinglow earth orbit (LEO) SARs [2]. | Yuanhao LI Dongyang AO Corneliu Octavian DUMITRU Cheng HU Mihai DATCU | 2019 | Science China(Information Sciences)2019，62，10： | 3 |
| 2 | Efficacy,safety and immunogenicity of hexavalent rotavirus vaccine in Chinese infants显示文摘A randomized,double-blind,placebo-controlled multicenter trial was conducted in healthy Chinese infants to assess the efficacy and safety of a hexavalent live human-bovine reassortant rotavirus vaccine(HRV)against rotavirus gastroenteritis(RVGE).A total of 6400 participants aged 6-12 weeks were enrolled and randomly assigned to either HRV(n?3200)or placebo(n?3200)group.All the subjects received three oral doses of vaccine four weeks apart.The vaccine efficacy(VE)against RVGE caused by rotavirus serotypes contained in HRV was evaluated from 14 days after three doses of administration up until the end of the second rotavirus season.VE against severe RVGE,VE against RVGE hospitalization caused by serotypes contained in HRV,and VE against RVGE,severe RVGE,and RVGE hospitalization caused by natural infection of any serotype of rotavirus were also investigated.All adverse events(AEs)were collected for 30 days after each dose.Serious AEs(SAEs)and intussusception cases were collected during the entire study.Our data showed that VE against RVGE caused by serotypes contained in HRV was 69.21%(95%CI:53.31-79.69).VE against severe RVGE and RVGE hospitalization caused by serotypes contained in HRV were 91.36%(95%CI:78.45-96.53)and 89.21%(95%CI:64.51-96.72)respectively.VE against RVGE,severe RVGE,and RVGE hospitalization caused by natural infection of any serotype of rotavirus were 62.88%(95%CI:49.11-72.92),85.51%(95%CI:72.74-92.30)and 83.68%(95%CI:61.34-93.11).Incidences of AEs from the first dose to one month post the third dose in HRV and placebo groups were comparable.There was no significant difference in incidences of SAEs in HRV and placebo groups.This study shows that this hexavalent reassortant rotavirus vaccine is an effective,well-tolerated,and safe vaccine for Chinese infants. | Zhiwei Wu Qingliang Li Yan Liu Huakun Lv Zhaojun Mo Fangjun Li Qingchuan Yu Fei Jin Wei Chen Yong Zhang Teng Huang Xiaosong Hu Wei Xia Jiamei Gao Haisong Zhou Xuan Bai Yueyue Liu Zhenzhen Liang Zhijun Jiang Yingping Chen Jiuwei Zhang Jialiang Du Biao Yang Bo Xing Yantao Xing Ben Dong Qinghai Yang Chen Shi Tingdong Yan Bo Ruan Haiyun Shi Xingliang Fan Dongyang Feng Weigang Lv Dong Zhang Xiangchu Kong Liuyifan Zhou Dinghong Que Hong Chen Zhongbing Chen Xiang Guo Weiwei Zhou Cong Wu Qingrong Zhou Yuqing Liu Jian Qiao Ying Wang Xinguo Li Kai Duan Yuliang Zhao Gelin Xu Xiaoming Yang | 2022 | Virologica Sinica2022，37，5： | 2 |
| 3 | Rutile to Titanite Transformation in Eclogites and its Geochemical Consequences:An Example from the Sumdo Eclogite,Tibet显示文摘The formation of titanite coronae after rutile is common in retrograde high-to ultrahigh-pressure meta-mafic rocks,which provides a good opportunity to address the geochemical behavior of HFSE in crustal environments.In the Sumdo eclogite,titanite occurs either as a corona around rutile grains or as semi-continuous veins cross-cutting the major foliation,whereas rutile grains occur either as inclusions in garnet or omphacite or as a relict core surrounded by titanite.Textural relationships and trace elements characteristics of rutile and titanite with different occurrences indicate that both minerals preferentially incorporate Nb and Hf over Ta and Zr in aqueous fluid.Moreover,the breakdown of omphacite and epidote could release substantial amounts of aqueous fluids enriched in Ca,Si,Fe and REE,which would react with rutile to form titanite coronae and veins.During this process,water-insoluble elements,like HFSE and HREE,behave like mobile elements,but they do not migrate substantially out of the system,instead,tending to react in situ.This suggests that the aqueous fluids released during the retrograde metamorphic reactions in mafic rocks could not substantially transfer fluidimmobile elements into the overlying mantle wedge in subduction environments. | ZHAO Linghao ZENG Lingsen GAO Li’e HU Mingyue SUN Dongyang ZHANG Lifei | 2023 | Acta Geologica Sinica(English Edition)2023，97，1： | 2 |

| 8 | Crystallization Regulation and Morphological Evolution for HTM-free Tin-Lead (1.28eV) Alloyed Perovskite Solar Cells显示文摘There have been huge achievements of all-perovskite tandem solar cells,which recently realized the highest power conversion efficiency of 24.8%.However,the complex device structure and complicated manufacture processes severely restrict the further development of all-perovskite tandem solar cells.In this work,we successfully fabricated high-efficiency hole transport material-free(HTM-free)Sn−Pb alloyed narrow bandgap perovskite solar cells(PSCs)by introducing guanidinium thiocyanate(GASCN)and hydroiodic acid(HI)into the perovskite precursor solution.GASCN and HI play a positive synergy effect during perovskite crystallization process resulting in larger grain size,fewer surface defects,and lower trap density to suppress the Sn^(2+)oxidation degradation.Furthermore,they could effectively adjust the energy level of perovskite materials,reduce the energy level difference between perovskite and ITO resulting in more efficiently transport of free hole charge carriers.As a result,with adding GASCN and HI,the achieved highest power conversion efficiency of HTM-free devices increased from 12.58%to 17.85%,which is one of the highest PCEs among all values reported to date for the HTM-free narrow-bandgap(1.2-1.4 eV)Sn−Pb binary PSCs.Moreover,the optimized device shows improved environmental stability.Our additive strategy manifests a remarkable step towards the facile,cost-efficient fabrication of HTM-free perovskite-based tandem solar cells with both high efficiency and simple fabrication process. | Hang Hu Xianyong Zhou Jiabang Chen Deng Wang Dongyang Li Yulan Huang Luozheng Zhang Yuanjun Peng Feng Wang Jingxia Huang Naichao Chen Liang Sun Xuesong Liu Xingzhu Wang Jianyong Ouyang Baomin Xu | 2023 | Energy & Environmental Materials2023，6，2： | 0 |
| 9 | Tetrathiafulvalene esters with high redox potentials and improved solubilities for non-aqueous redox flow battery applications显示文摘The exploitation of high performance redox-active substances is critically important for the development of non-aqueous redoxflow batteries.Herein,three tetrathiofulvalene(TTF)derivatives with different substitution groups,namely TTF diethyl ester(TTFDE),TTF tetramethyl ester(TTFTM),and TTF tetraethyl ester(TTFTE),are prepared and their energy storage properties are evaluated.It has been found that the redox potential and solubility of these TTF derivatives in conventional carbonate electrolytes increases with the number of ester groups.The battery with a catholyte of 0.2 mol L^(-1) of TTFTE delivers a specific capacity of more than 10 Ah L^(-1) at the current density of 0.5 C with two discharge voltage platforms locating at as high as 3.85 and 3.60 V vs.Li/Liþ.Its capacity retention can be improved from 2.34 Ah L^(-1) to 3.60 Ah L^(-1) after 100 cycles by the use of an anion exchange membrane to block the crossover of TTF species.The excellent cycling stability of the TIF esters is supported by their well-delocalized electrons,as revealed by the density function theory calculations.Therefore,the introduction of more and larger electron-withdrawing groups is a promising strategy to simultaneously increase the redox-potential and solubility of redox-active ma-terials for non-aqueous redoxflow batteries. | Weikang Hu Jiaqi Xu Nanjie Chen Zongcai Deng Yuekun Lai Dongyang Chen | 2024 | Green Energy & Environment2024，9，5： | 0 |

| 11 | Identification of COL3A1 variants associated with sporadic thoracic aortic dissection: a case-control study显示文摘Thoracic aortic dissection(TAD)without familial clustering or syndromic features is known as sporadic TAD(STAD).So far,the genetic basis of STAD remains unknown.Whole exome sequencing was performed in 223 STAD patients and 414 healthy controls from the Chinese Han population(N=637).After population structure and genetic relationship and ancestry analyses,we used the optimal sequence kernel association test to identify the candidate genes or variants of STAD.We found that COL3A1 was significantly relevant to STAD(P=7.35×10^(−6))after 10000 times permutation test(P=2.49×10^(−3)).Moreover,another independent cohort,including 423 cases and 734 non-STAD subjects(N=1157),replicated our results(P=0.021).Further bioinformatics analysis showed that COL3A1 was highly expressed in dissected aortic tissues,and its expression was related to the extracellular matrix(ECM)pathway.Our study identified a profile of known heritable TAD genes in the Chinese STAD population and found that COL3A1 could increase the risk of STAD through the ECM pathway.We wanted to expand the knowledge of the genetic basis and pathology of STAD,which may further help in providing better genetic counseling to the patients. | Yanghui Chen Yang Sun Zongzhe Li Chenze Li Lei Xiao Jiaqi Dai Shiyang Li Hao Liu Dong Hu Dongyang Wu Senlin Hu Bo Yu Peng Chen Ping Xu Wei Kong Dao Wen Wang | 2021 | Frontiers of Medicine2021，15，3： | 0 |
| 12 | Experimental realization of chiral Landau levels in two-dimensional Dirac cone systems with inhomogeneous effective mass显示文摘Chiral zeroth Landau levels are topologically protected bulk states.In particle physics and condensed matter physics,the chiral zeroth Landau level plays a significant role in breaking chiral symmetry and gives rise to the chiral anomaly.Previous experimental works on such chiral Landau levels are mainly based on three-dimensional Weyl degeneracies coupled with axial magnetic fields.Their realizations using two-dimensional Dirac point systems,being more promising for future applications,were never experimentally realized before.Here we propose an experimental scheme for realizing chiral Landau levels in a two-dimensional photonic system.By introducing an inhomogeneous effective mass through breaking local parity-inversion symmetries,a synthetic in-plane magnetic field is generated and coupled with the Dirac quasi-particles.Consequently,the zeroth-order chiral Landau levels can be induced,and the one-way propagation characteristics are experimentally observed.In addition,the robust transport of the chiral zeroth mode against defects in the system is also experimentally tested.Our system provides a new pathway for the realization of chiral Landau levels in two-dimensional Dirac cone systems,and may potentially be applied in device designs utilizing the chiral response and transport robustness. | Hongwei Jia Mudi Wang Shaojie Ma Ruo-Yang Zhang Jing Hu Dongyang Wang Che Ting Chan | 2023 | Light(Science & Applications)2023，12，8： | 0 |
| 13 | Whole-exome sequencing reveals genetic risks of early-onset sporadic dilated cardiomyopathy in the Chinese Han population显示文摘To reveal genetic risks of early-onset sporadic dilated cardiomyopathy(DCM) patients in the Chinese Han population, we enlisted 363 DCM cases and 414 healthy controls. Whole-exome sequencing and phenotypic characterization were conducted. In total, we identified 26 loss-of-function(LOF) candidates and 66 pathogenic variants from 33 genes, most of which were novel.The deleterious variants can account for 25.07%(91/363) of all patients. Furthermore, rare missense variants in 21 genes were found to be significantly associated with DCM in burden tests. Other than rare variants, twelve common SNPs were significantly associated with an increased risk of DCM in allele-based genetic model association analysis. Of note, in the cumulative risk model, high-risk subjects had a 3.113-fold higher risk of developing DCM than low-risk subjects. Also, DCM in the high-risk group had a younger age of onset than that in the low-risk group. In terms of cardiac function, the mean left ventricular ejection fraction of patients with the deleterious variants was lower than those without(27.73%±10.02% vs. 30.61%±10.85%, P=0.026).To conclude, we mapped a comprehensive atlas of genetic risks in Chinese patients with DCM that might lead to new insights into the mechanisms and risk stratification for DCM. | Lei Xiao Dongyang Wu Yang Sun Dong Hu Jiaqi Dai Yanghui Chen Daowen Wang | 2022 | Science China(Life Sciences)2022，65，4： | 0 |
| 14 | Evaluating students' learning situations using “Four-quadrant law”显示文摘Evaluation is widely acknowledged as a powerful means of improving the quality of education and it is a very important component of the education system. However, the current mainstream evaluation method is based on the examination as the common way, which has very limited help to instructors' teaching. In this paper, based on an online learning platform named 'educoder', we design an evaluation method by using 'Four-quadrant law', which divides students' learning situations into four types. In addition, we provide some suggestions for instructors about how to give targeted teaching to different students in each type. We verify that our method is useful by setting up experiments. The experiment results show that our method can effectively improve the quality of instructors' teaching. | Jinze Liu Dongyang Hu Xunhui Zhang Tao Wang Yue Yu Gang Yin | 2018 | 计算机教育2018，，12： | 0 |
| 15 | Electro-spraying/spinning: A novel battery manufacturing technology显示文摘Lithium-ion battery(LIB) industry seems to have met its bottle neck in cutting down producing costs even though much efforts have been put into building a complete industrial chain. Actually, manufacturing methods can greatly affect the cost of battery production. Up to now, lithium ion battery producers still adopt manufacturing methods with cumbersome sub-components preparing processes and costly assembling procedures, which will undoubtedly elevate the producing cost. Herein, we propose a novel approach to directly assemble battery components(cathode, anode and separator) in an integrated way using electro-spraying and electro-spinning technologies. More importantly, this novel battery manufacturing method can produce LIBs in large scale, and the products show excellent mechanical strength, flexibility, thermal stability and electrolyte wettability. Additionally, the performance of the as-prepaed Li Fe PO_(4)||graphite full cell produced by this new method is comparable or even better than that produced by conventional manufacturing approach. In brief, this work provides a new promising technology to prepare LIBs with low cost and better performance. | Zhuan Hu Jiaxin Hao Dongyang Shen Caitian Gao Zhaomeng Liu Jianguo Zhao Bingan Lu | 2024 | Green Energy & Environment2024，9，1： | 0 |
