| 1 | New Discovery of Molybdenite in the Dongping Gold Deposit, Hebei Province, China and its Re-Os Geochronological Implications显示文摘The Dongping gold deposit is located on the northern margin of the North China Craton,and is the largest alkaline pluton-related gold deposit in China(Bao et al.,2014),which is characterized by its large amounts of tellurides.The deposit is largely hosted in the Shuiquangou syenitic complex and consists of auriferous quartz veins and disseminated sulfide ores.It has been extensively studied since its discovery in the 1980s;however the geochronology and genesis of the deposit are still controversial.Nie(1998)considered that the deposit was formed in the Devonian. | WANG Dazhao LIU Jiajun ZHAI Degao ZHEN Shimin WANG Jiang YANG Xi'an | 2019 | Acta Geologica Sinica(English Edition)2019，93，3： | 5 |
| 2 | Namib desert beetle inspired special patterned fabric with programmable and gradient wettability for efficient fog harvesting显示文摘Efficient collection of water from fog provides a potential solution to solve the global freshwater shortage problem, particularly in the desert or arid regions. In this work, a flexible and highly efficient fog collector was prepared by mimicking the back exoskeleton structure of the Namib desert beetle. The improved fog collector was constructed by a superhydrophobic-superhydrophilic patterned fabric via a simple weaving method, followed by in-situ deposition of copper particles. Compared with the conventional fog collector with a plane structure, the fabric has shown a higher water-harvesting rate at 1432.7 mg/h/cm2,owing to the biomimetic three-dimensional structure, its enhanced condensation performance enabled by the copper coating and the rational distribution of wetting units. The device construction makes use of the widely available textile materials through mature manufacturing technology, which makes it highly suitable for large-scale industrial production. | Zhihua Yu Huimei Zhang Jianying Huang Shuhui Li Songnan Zhang Yan Cheng Jiajun Mao Xiuli Dong Shouwei Gao Shanchi Wang Zhong Chen Yaoxing Jiang Yuekun Lai | 2021 | Journal of Materials Science & Technology2021，，2： | 5 |
| 3 | Routing valley exciton emission of a WS_(2) monolayer via delocalized Bloch modes of in-plane inversion-symmetry-broken photonic crystal slabs显示文摘The valleys of two-dimensional transition metal dichalcogenides(TMDCs)offer a new degree of freedom for information processing.To take advantage of this valley degree of freedom,on the one hand,it is feasible to control valleys by utilizing different external stimuli,such as optical and electric fields.On the other hand,nanostructures are also used to separate the valleys by near-field coupling.However,for both of the above methods,either the required low-temperature environment or low degree of coherence properties limit their further applications.Here,we demonstrate that all-dielectric photonic crystal(PhC)slabs without in-plane inversion symmetry(C_(2) symmetry)can separate and route valley exciton emission of a WS2 monolayer at room temperature.Coupling with circularly polarized photonic Bloch modes of such PhC slabs,valley photons emitted by a WS_(2) monolayer are routed directionally and are efficiently separated in the far field.In addition,far-field emissions are directionally enhanced and have long-distance spatial coherence properties. | Jiajun Wang Han Li Yating Ma Maoxiong Zhao Wenzhe Liu Bo Wang Shiwei Wu Xiaohan Liu Lei Shi Tian Jiang Jian Zi | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 4 | Deformation Forecasting of Huangtupo Riverside Landslide in the Case of Frequent Microseisms显示文摘Ever since the impoundment of Three Gorges Reservoir(TGR), the seismicity in head region of TGR has increased significantly. Coupled with wide fluctuation of water level each year, it becomes more important to study the deformation forecasting of landslides beside TGR. As a famous active landslide beside TGR, Huangtupo riverside landslide is selected for a case study. Based on long term water level fluctuation and seismic monitoring, three typical adverse conditions are determined. With the established 3D numerical landslide model, seepage-dynamic coupling calculation is conducted under the seismic intensity of V degree. Results are as follows: 1. the dynamic water pressure formed by water level fluctuation will intensify the deformation of landslide; 2. under seismic load, the dynamic hysteresis is significant in defective geological bodies, such as weak layer and slip zone soil, because of much higher damping ratios, the seismic accelerate would be amplified in these elements; 3. microseisms are not intense enough to cause the landslide instability suddenly, but long term deformation accumulation effect of landslide should be paid more attention; 4. in numerical simulation, the factors of unbalance force and excess pore pressure also can be used in forecasting deformation tendency of landslide. | Jiwei Jiang Wei Xiang Wei Zhang Jiajun Pan | 2016 | Journal of Earth Science2016，27，1： | 4 |
| 5 | Superresolution imaging of telomeres with continuous wave stimulated emission depletion (STED) microscope显示文摘The significant role of telomeres in cells has attracted much attention since they were discovered.Fluorescence imaging is an effective method to study subcellular structures like telomeres.However,the diffraction limit of traditional optical microscope hampers further investigation on them.Recent progress on superresolution fluorescence microscopy has broken this limit.In this work,we used stimulated emission depletion(STED) microscope to observe fluorescence-labeled telomeres in interphase cell nuclei.The results showed that the size of fluorescent puncta representing telomeres under the STED microscope was much smaller than that under the confocal microscope.Two adjacent telomeres were clearly separated via STED imaging,which could hardly be discriminated by confocal microscopy due to the diffraction limit.We conclude that STED microscope is a more powerful tool that enable us to obtain detailed information about telomeres. | Shaopeng Wang Suhui Deng Xiaoqing Cai Shangguo Hou Jiajun Li Zhaoshuai Gao Jiang Li Lihua Wang Chunhai Fan | 2016 | Science China Chemistry2016，59，11： | 3 |
| 6 | Antimony doped Cs2SnCl6 with bright and stable emission显示文摘Lead halide perovskites,with high photoluminescence efficiency and narrow・band emission,are promising materials for display and lighting.However,the lead toxicity and environmental sensitivity hinder their potential applications.Herein,a new antimony・doped lead-free inorganic perovskites variant Cs2SnCl6:xSb is designed and synthesized.The perovskite variant Cs2SnCl6:xSb exhibits a broadband orange-red emission,with a photoluminescence quantum yield(PLQY)of 37%.The photoluminescence of Cs2SnCl6:xSb is caused by the ionoluminescence of Sb3+within Cs2SnCl6 matrix,which is verified by temperature dependent photoluminescence(PL)and PL decay measurements.In addition,the all inorganic structure renders Cs2SnCl6:xSb with excellent thermal and water stability.Finally,a white light-emitting diode(white-LED)is fabricated by assembling Cs2SnCl6:0.59%Sb,Cs2SnCl6:2.75%Bi and Ba2Sr2SiO4:Eu2+onto the commercial UV LED chips,and the color rendering index(CRI)reaches 81. | Jinghui LI Zhifang TAN Manchen HU Chao CHEN Jiajun LUO Shunran LI Liang GAO Zewen XIAO Guangda NIU Jiang TANG | 2019 | Frontiers of Optoelectronics2019，12，4： | 2 |
| 7 | A manual inspection of Defects4J bugs and its implications for automatic program repair显示文摘Automatic program repair techniques, which target to generate correct patches for real-world defects automatically, have gained a lot of attention in the last decade. Many different techniques and tools have been proposed and developed. However, even the most sophisticated automatic program repair techniques can only repair a small portion of defects while producing a large number of incorrect patches.A possible reason for the low performance is the test suites of real-world programs are usually too weak to guarantee the behavior of a program. To understand to what extent defects can be fixed with exiting test suites, we manually analyzed 50 real-world defects from Defects4J, where a large portion(i.e., 82%) of them were correctly fixed. This result suggests that there is much room for the current automatic program repair techniques to improve. Furthermore, we summarized seven fault localization and seven patch generation strategies that are useful in localizing and fixing these defects, and compared those strategies with current techniques. The results indicate potential directions to improve automatic program repair in the future. | Jiajun JIANG Yingfei XIONG Xin XIA | 2019 | Science China(Information Sciences)2019，62，10： | 2 |
| 8 | Amur tiger stripes:individual identification based on deep convolutional neural network显示文摘The automatic individual identification of Amur tigers(Panthera tigris altaica)is important for population monitoring and making effective conservation strategies.Most existing research primarily relies on manual identifi-cation,which does not scale well to large datasets.In this paper,the deep convolution neural networks algorithm is constructed to implement the automatic individual identification for large numbers of Amur tiger images.The experimental data were obtained from 40 Amur tigers in Tieling Guaipo Tiger Park,China.The number of images collected from each tiger was approximately 200,and a total of 8277 images were obtained.The experiments were carried out on both the left and right side of body.Our results suggested that the recognition accuracy rate of left and right sides are 90.48%and 93.5%,respectively.The accuracy of our network has achieved the similar level compared to other state of the art networks like LeNet,ResNet34,and ZF_Net.The running time is much shorter than that of other networks.Consequently,this study can provide a new approach on automatic individual identification technology in the case of the Amur tiger. | Chunmei SHI Dan LIU Yonglu CUI Jiajun XIE Nathan James ROBERTS Guangshun JIANG | 2020 | Integrative Zoology2020，15，6： | 2 |
| 9 | Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection显示文摘Sensitive and fast detection of neutrons and gamma rays is vital for homeland security,high-energy physics,and proton therapy.Fast-neutron detectors rely on light organic scintillators,andγ-ray detectors use heavy inorganic scintillators and semiconductors.Efficient mixed-field detection using a single material is highly challenging due to their contradictory requirements.Here we report hybrid perovskites(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)that combine light organic cations and heavy inorganic skeletons at a molecular level to achieve unprecedented performance for mixed-field radiation detection.High neutron absorption due to a high density of hydrogen,strong radiative recombination within the highly confined[PbX_(6)]^(4-)layer,and sub-nanometer distance between absorption sites and radiative centers,enable a light yield of 41000 photons/MeV,detection pulse width of 2.97 ns and extraordinary linearity response toward both fast neutrons andγ-rays,outperforming commonly used fast-neutron scintillators.Neutron energy spectrum,time-of-flight based fast-neutron/γ-ray discrimination and neutron yield monitoring were all successfully achieved using(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)detectors.We further demonstrate the monitoring of reaction kinetics and total power of a nuclear fusion reaction.We envision that molecular hybridized scintillators open a new avenue for mixed-field radiation detection and imaging. | Mengling Xia Guangda Niu Linyue Liu Runlong Gao Tong Jin Pengying Wan Weicheng Pan Xianpeng Zhang Zuoxiang Xie Sam Teale Zenghua Cai Jiajun Luo Shan Zhao Haodi Wu Shiyou Chen Zhiping Zheng Qingguo Xie Xiaoping Ouyang Edward HSargent Jiang Tang | 2022 | InfoMat2022，4，9： | 2 |
| 10 | Sub-diffraction-limit cell imaging using a super-resolution microscope with simplified pulse synchronization显示文摘Stimulated emission depletion(STED) microscope is one of the most prominent super-resolution bio-imaging instruments, which holds great promise for ultrahigh-resolution imaging of cells. To construct a STED microscope, it is challenging to realize temporal synchronization between the excitation pulses and the depletion pulses. In this study, we present a simple and low-cost method to achieve pulse synchronization by using a condensed fluorescent dye as a depletion indicator. By using this method, almost all the confocal microscopes can be upgraded to a STED system without losing its original functions. After the pulse synchronization,our STED system achieved sub-100-nm resolution for fluorescent nanospheres and single-cell imaging. | Zhaoshuai Gao Suhui Deng Jiang Li Kun Wang Jiajun Li Lihua Wang Chunhai Fan | 2017 | Science China Chemistry2017，60，10： | 2 |

| 12 | Single-event burnout hardening of planar power MOSFET with partially widened trench source显示文摘We present a single-event burnout(SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional(3 D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region(P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer(LET),which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to0.7 p C/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications. | Jiang Lu Hainan Liu Xiaowu Cai Jiajun Luo Bo Li Binhong Li Lixin Wang Zhengsheng Han | 2018 | Journal of Semiconductors2018，39，3： | 1 |

| 14 | Upregulation of Rpn10 promotes tumor progression via activation of the NF-κB pathway in clear cell renal cell carcinoma显示文摘The ubiquitin-proteasome system(UPS)plays a central role in regulating protein homeostasis in tumor progression.The proteasome subunit Rpn10 is associated with the progression of several tumor types.However,little is known regarding the role of Rpn10 in clear cell renal cell carcinoma(ccRCC).In this study,we found that overexpression of Rpn10 increased ccRCC cell proliferation,migration,and invasion.Silencing Rpn10 expression resulted in decreased cell proliferation,migration,and invasion in ccRCC cells.Knockdown of Rpn10 inhibits tumor growth and cell proliferation in vivo.Furthermore,we demonstrated that Rpn10 increased cell proliferation,migration,and invasion via regulation of the nuclear factor kappa B(NF-κB)pathway.Rpn10 directly promoted inhibitor of nuclear factor-kappa B alpha(IκBcx)degradation through the UPS.Moreover,we observed that upregulation of Rpn10 or downregulation of kBa in ccRCC was associated with poor prognosis.We found that the combination of these two parameters was a more powerful predictor of poor prognosis than either parameter alone.Collectively,these findings provide evidence that Rpn10 promotes the progression of ccRCC by regulation of the NF-κB pathways and is a prognostic indicator for patients with ccRCC. | Tingting Huang Wei Tian Qingqing Zhou Jiajun Li Zhiyuan Jiang Jinsi Chen Chao Ge Hua Tian | 2021 | Acta Biochimica et Biophysica Sinica2021，53，8： | 1 |
| 15 | Distribution of reactive aluminum under the influence of mesoscale eddies in the western South China Sea显示文摘To understand the distribution of aluminum(Al) under the influence of mesocale eddies in the western South China Sea(SCS), sea level anomaly, geostrophic current, environmental parameters and reactive Al were investigated in the western SCS in August 2013. The highest reactive Al concentration((180±64) nmol/L) was observed in the surface waters, indicating a substantial atmospheric input. Vertically, the reactive Al decreased from the surface high concentration to the subsurface minima at the depth of chlorophyll a(Chl a) maxima and then increased again with depth at most of the stations. The average concentration of reactive Al in the upper 100 m water column was significantly lower in the cyclonic eddy((137±6) nmol/L) as compared with that in the noneddy waters((180±21) nmol/L). By contrast, the average concentrations of Chl a and silicate in the upper 100 m water column were higher in the cyclonic eddy and lower in the anticyclonic eddy. There was a significant negative correlation between the average concentrations of reactive Al and Chl a in the upper 100 m water column. The vertical distribution of reactive Al and the negative correlation between reactive Al and Chl a both suggest that the reactive Al in the upper water column was significantly influenced by biological removal processes. Our results indicate that mesoscale eddies could regulate the distribution of reactive Al by influencing the primary production and phytoplankton community structure in the western SCS. | LIU Jiaxing ZHOU Linbin TAN Yehui WANG Qionga HU Zifeng LI Jiajun JIANG Xin KE Zhixin | 2017 | Acta Oceanologica Sinica2017，36，6： | 1 |

| 17 | Perfect light absorber with a PT phase transition via coupled topological interface states显示文摘Recently,the concepts of parity–time(PT)symmetry and band topology have inspired many novel ideas for light manipulation in their respective directions.Here we propose and demonstrate a perfect light absorber with a PT phase transition via coupled topological interface states(TISs),which combines the two concepts in a onedimensional photonic crystal heterostructure.By fine tuning the coupling between TISs,the PT phase transition is revealed by the evolution of absorption spectra in both ideal and non-ideal PT symmetry cases.Especially,in the ideal case,a perfect light absorber at an exceptional point with unidirectional invisibility is numerically obtained.In the non-ideal case,a perfect light absorber in a broken phase is experimentally realized,which verifies the possibility of tailoring non-Hermiticity by engineering the coupling.Our work paves the way for novel effects and functional devices from the exceptional point of coupled TISs,such as a unidirectional light absorber and exceptional-point sensor. | JIAJUN ZHENG HAIYANG ZHOU JUNYANG LI YUFEI WANG HAITAO JIANG YUNHUI LI ZHIWEI GUO YAPING YANG GUIQIANG DU WANHUA ZHENG YONG SUN HONG CHEN | 2023 | Photonics Research2023，11，4： | 0 |
| 18 | Correlation between human seizure-related gene 6 variants and idiopathic generalized epilepsy in a Southern Chinese Han population显示文摘This study sought to analyze the genotype and gene mutations of human seizure-related gene 6 in 98 patients with idiopathic generalized epilepsy (non-febrile seizures), who were selected from three generations of the Chinese Han population living in Shanghai, Zhejiang Province, Wuxi of Jiangsu Province, and Jiangxi Province of Southern China. Twenty-six patients' parents were available as a first-degree relatives group and 100 biologically unrelated healthy controls were collected as the control group. Based on the age of onset and seizure type, the patients were divided into six subgroups. Polymerase chain reaction and DNA direct sequencing analysis showed that the most frequent mutations c.1249dupC (p.Gly418Argfx31) and c.1636A > G (p.Thr546Ala) were detected in some idiopathic generalized epilepsy patients and their asymptomatic first-degree relatives (30.6% vs. 19.2% and 11.2% vs. 26.9%). A novel mutation c.1807G > A (p.Val603Met) was found in a patient with late-onset idiopathic generalized epilepsy. There was no significant difference in the incidence of these three mutations among the different subgroups of idiopathic generalized epilepsy and controls. Thus, further analysis of a larger population is needed to confirm the assumption that human seizure-related gene 6 is a susceptibility gene for idiopathic generalized epilepsy with various sub-syndromes. | Jianming Jiang Xiao ling Chen Wenting Liu Yan Zhao Yangtai Guan Yan Han FengWang Jiajun Lu Zhiliang Yu Zhenfang Du Xianning Zhang | 2012 | Neural Regeneration Research2012，7，2： | 0 |

| 20 | Causative fault and seismogenic mechanism of the 2010 Suining M5.0 earthquake from joint modeling of seismic and InSAR data显示文摘Although the Sichuan basin is a stable block with low historical seismicity,the Suining M5.0 earthquake on January31,2010 occurred near the center of the basin,causing casualty and substantial damage.Previous studies have shown that the earthquake is very shallow and may occur in the sedimentary cover rocks,but its causative fault has not been identified.Based on local broadband seismic waveform data as well as a pair of ALOS PALSAR ascending orbit data,we explore the seismogenic mechanism via further constraining the source depth and the ruptured fault.The earthquake caused ground uplift in the southeast of the epicenter area,with a maximum line of sight displacement of about 13.6 cm,much larger than the displacement caused by a M5 earthquake at a typical depth of 10 km,which indicates that the earthquake is very shallow.Through joint inversion of seismic waveform and InSAR data,we obtain the moment magnitude of Suining earthquake as MW4.5,with the strike,dip,and rake of its fault plane as 17°,66° and 90°,respectively,and the centroid depth less than 1 km,supporting that the earthquake occurred at the shallow part of a high angle thrust fault dipping to the southeast.It is further confirmed that the earthquake may be triggered by the diffusion of high-pressure fluid migrating from the underside gas reservoir. | Wangwang GU Sidao NI Shuofan WANG Baolong ZHANG Xinglin LEI Risheng CHU Aizhi GUO Qiang SHEN Hansheng WANG Liming JIANG Minhan SHENG Jiajun CHONG | 2023 | Science China Earth Sciences2023，66，8： | 0 |
