| 1 | Terrestrial carbon sinks in China and around the world and their contribution to carbon neutrality显示文摘Enhancing the terrestrial ecosystem carbon sink(referred to as terrestrial C sink) is an important way to slow down the continuous increase in atmospheric carbon dioxide(CO_(2)) concentration and to achieve carbon neutrality target.To better understand the characteristics of terrestrial C sinks and their contribution to carbon neutrality,this review summarizes major progress in terrestrial C budget researches during the past decades,clarifies spatial patterns and drivers of terrestrial C sources and sinks in China and around the world,and examines the role of terrestrial C sinks in achieving carbon neutrality target.According to recent studies,the global terrestrial C sink has been increasing from a source of (-0.2±0.9) Pg C yr^(-1)(1 Pg=1015g)in the 1960s to a sink of (1.9±1.1) Pg C yr^(-1) in the 2010s.By synthesizing the published data,we estimate terrestrial C sink of 0.20–0.25 Pg C yr^(-1) in China during the past decades,and predict it to be 0.15–0.52 Pg C yr^(-1) by 2060.The terrestrial C sinks are mainly located in the mid-and high latitudes of the Northern Hemisphere,while tropical regions act as a weak C sink or source.The C balance differs much among ecosystem types:forest is the major C sink;shrubland,wetland and farmland soil act as C sinks;and whether the grassland functions as C sink or source remains unclear.Desert might be a C sink,but the magnitude and the associated mechanisms are still controversial.Elevated atmospheric CO_(2) concentration,nitrogen deposition,climate change,and land cover change are the main drivers of terrestrial C sinks,while other factors such as fires and aerosols would also affect ecosystem C balance.The driving factors of terrestrial C sink differ among regions.Elevated CO_(2) concentration and climate change are major drivers of the C sinks in North America and Europe,while afforestation and ecological restoration are additionally important forcing factors of terrestrial C sinks in China.For future studies,we recommend the necessity for intensive and long-term ecosystem C monitoring over broad geographic scale to improve terrestrial biosphere models for accurately evaluating terrestrial C budget and its dynamics under various climate change and policy scenarios. | Yuanhe Yang Yue Shi Wenjuan Sun Jinfeng Chang Jianxiao Zhu Leiyi Chen Xin Wang Yanpei Guo Hongtu Zhang Lingfei Yu Shuqing Zhao Kang Xu Jiangling Zhu Haihua Shen Yuanyuan Wang Yunfeng Peng Xia Zhao Xiangping Wang Huifeng Hu Shiping Chen Mei Huang Xuefa Wen Shaopeng Wang Biao Zhu Shuli Niu Zhiyao Tang Lingli Liu Jingyun Fang | 2022 | Science China(Life Sciences)2022，65，5： | 32 |
| 2 | 2 K superfluid helium cryogenic vertical test system for superconducting cavity of ADS Injector I显示文摘Purpose The accelerator-driven subcritical system(ADS)is the internationally recognized key technology of nuclear waste problem treatment,of which superconducting proton linac is an important part.With the support of the strategic science and technology pilot project of the Chinese Academy of Sciences,the Institute of High Energy Physics of the Chinese Academy of Sciences took the lead in the research of 325 MHz superconducting proton linac,which is called ADS Injector I.The superconducting accelerator part of ADS Injector I mainly consists of 14 spoke-type superconducting cavities withβ0.12.At the same time,the research work of various cavities with differentβvalues and different frequencies is also carried out to lay the technical and technological foundation for ADS main accelerator.The only way to determine whether the superconducting cavity can reach the design target and whether it can be installed into the cryostat is the vertical test at cryogenic.As the only way to test the microwave performance of the superconducting cavity at low temperature,the vertical test can accurately test the acceleration gradient Eacc and the corresponding quality factor Q0 of the superconducting cavity.The design and construction of the superconducting cavity vertical test facility is based on the practical needs of the pilot project and the long-term development of the superconducting accelerator.Methods This paper mainly introduces the design and construction of the cryogenic vertical test system for the superconducting cavity of ADS Injector I,including the system scheme design,process design,heat load analysis,2 K superfluid helium obtaining method,system commissioning and operation,etc.Results and Conclusion The static heat leakage at 2 K of the 2 K superfluid helium vertical test system of ADS Injector I is 1.624W,which has reached the international advanced level.The 2 K superfluid helium vertical test system of ADS Injector I after constructed not only meets the test requirements of ADS pilot project,but also conducts 4 K and 2 K vertical tests for other different types of superconducting cavities and relevant cryogenic experiments. | Rui Ge Liangrui Sun Miaofu Xu Rui Ye Xiangzhen Zhang Minjing Sang Ruixiong Han Zhuo Zhang Jiehao Zhang Lin Bian Mei Li Changcheng Ma Tongxian Zhao Yongcheng Jiang Zhengze Chang Shaopeng Li | 2020 | Radiation Detection Technology and Methods2020，4，2： | 2 |
| 3 | Yield and quality properties of silage maize and their influencing factors in China显示文摘Silage maize(Zea mays L.) is one of the most important forages in the world, and its yield and quality properties are critical parameters for livestock production and assessment of forage values. However, relationships between its yield and quality properties and the controlling factors are not well documented. In this study, we collected 5,663 observations from 196 publications across the country to identify the relationships between yield and quality properties of silage maize and to assess the impact of management practices and climatic factors on its yield and quality in China. The average dry matter yield of silage maize was(19.98±6.93) Mg ha^(-1), and the average value of crude protein, ether extract, crude ash, crude fiber, acid detergent fiber, neutral detergent fiber, nitrogen-free extract, and relative feed value was 7.86%±1.71%, 2.53%±1.01%, 5.05%±1.66%,23.97%±6.34%, 27.62%±7.12%, 51.60%±9.85%, 59.68%±7.72%, and 131.17±31.49, respectively. In general, its nutritive value decreased as its yield increased. Increasing planting density could increase the yield but inhibit the nutritive values, while increasing fertilization could benefit the nutritive values. Geographically, the yield increased and the nutritive value decreased from warm(south) to cold(north) regions. The length of growth duration was a major controlling factor for the patterns of these properties. Our findings provide insights for police-makers to make strategy for achieving high yield and good quality of silage maize and help local people to implement better management practices. | Mengying Zhao Yinping Feng Yue Shi Haihua Shen Huifeng Hu Yongkai Luo Longchao Xu Jie Kang Aijun Xing Shaopeng Wang Jingyun Fang | 2022 | Science China(Life Sciences)2022，65，8： | 2 |

| 6 | Assessment of the cytotoxic and mutagenic potential of the Jialu River and adjacent groundwater using human-hamster hybrid cells显示文摘The Jialu River in China has been seriously polluted by the direct discharge of industrial and domestic wastewater. The predominant contaminants of the Jialu River and its adjacent groundwater were recently investigated. However, the potential genotoxic impact of polluted water on human health remains to be clarified. Here, we used human–hamster hybrid(A_L) cells, which are sensitive for detecting environmental mutagens. We found that the cytotoxicity and mutagenicity of the groundwater in the Jialu River basin were influenced by the infiltration of the Jialu River. Hydrological periods significantly affected the cytotoxicity, but not the mutagenic potential, of surface and groundwater. Further, the mutagenic potential of groundwater samples located < 1 km from the Jialu River(S_(M-2) water samples) was detected earlier than that of groundwater samples located approximately 20 km from the Jialu River(S_N water samples). Because of high cytotoxicity, the mutagenic potential of water samples from the Jialu River(S_(M-1) water samples) was not significantly enhanced compared with that of untreated controls. To further assess the mutagenic dispersion potential, an artificial neural network model was adopted. The results showed that the highest mutagenic potential of groundwater was observed approximately 10 km from the Jialu River. Although further investigation of mutagenic spatial dispersion is required, our data are significant for advancing our understanding of the origin, dispersion,and biological effects of water samples from polluted areas. | Xiaofei Wang Guoping Zhao Hongqiang Wang Junting Liang Shengmin Xu Shaopeng Chen An Xu Lijun Wu | 2018 | Journal of Environmental Sciences2018，30，8： | 1 |
| 7 | Ball-milling Synthesis of Single-atom Cu Anchored on N-Doped Carbon for Mimicking Peroxidase显示文摘Nanozymes have shown great potential for life sciences owing to their distinct advantages,such as low cost and high stability,compared with natural enzymes.Despite significant progress,state-of-art nanozymes commonly suffer from relatively low specific activities.Herein,we propose a promising to address this issue by creating single-atom nanozymes.A ball-milling-assisted strategy has been developed to induce the transformation of Cu species from bulk to single atoms.The highly-simplified steps allow a large-scale synthesis,that over 4.2 g of single-atom Cu-N doped carbon nanozymes can be achieved in one pot.It exhibits a remarkably improved peroxidase-like activity and stability compared with N doped C anchored Cu nanoparticles.Further experimental firmly reveals the crucial role of the single-atom Cu site that can generate more active·OH species for boosting the catalytic process. | XU Henan ZHANG Lingling WANG Huilin ZHANG Shaopeng LI Wei WANG Xiao SONG Shuyan WANG Daguang SHI Zhan | 2023 | Chemical Research in Chinese Universities2023，39，6： | 0 |

| 9 | Aberrant expression of the extracellular matrix component Biglycan regulated by Hedgehog signalling promotes colorectal cancer cell proliferation显示文摘Hedgehog(Hh)signalling plays essential roles in regulating embryonic development and contributes to tumour initiation,growth and progression in multiple cancers.The detailed mechanism by which Hh signalling participates in tumour growth warrants thorough study,although several downstream target genes have been identified.Herein,a set of novel targets of Hh signalling was identified in multiple types of tumour cells via RNA-Seq analysis.Among these targets,the expression regulation and oncogenic function of the extracellular matrix component biglycan(BGN)were investigated.Further investigation verified that Hh signalling activates the expression of BGN via the transcription factor Gli2,which directly binds to the promoter region of BGN.Functional assays revealed that BGN facilitates tumour cell growth and proliferation in colorectal cancer(CRC)cells,and xenograft assays confirmed that BGN also promotes tumour growth in vivo.Moreover,analysis of clinical CRC samples showed that both the protein and mRNA levels of BGN are increased in CRC tissues compared to those in adjacent tissues,and higher expression of BGN is correlated with poorer prognosis of CRC patients,further confirming the function of BGN in CRC.Taken together,aberrantly activated Hh signalling increases the expression of BGN,possibly regulates the extracellular matrix,and thereby promotes tumour growth in CRC. | Shaopeng Zeng Feifei Zhou Yiqing Wang Zhenyu Zhai Linlin Xu Hailong Wang Xinping Chen Shiwen Luo Minzhang Cheng | 2022 | Acta Biochimica et Biophysica Sinica2022，54，2： | 0 |
| 10 | Enhanced radiosensitivity by 6-thio-dG via increasing telomere dysfunction and ataxia telangiectasia mutated inhibition in non-small cell lung cancer显示文摘Objective:To investigate the radiosensitivity of 6-thio-dG and its underlying molecular mechanisms in non-small cell lung cancer(NSCLC).Methods:H1299 and A549 NSCLC cells were pretreated with 6-thio-dG for one week and then exposed toγ-irradiation.Cell proliferation and survival were quantified using clonogenic assays.DNA damage was assessed using immunofluorescence forγH2AX.Telomere dysfunction-induced foci analysis was performed by the colocalization of telomere signals(FISH)andγH2AX.Telomere fusion was defined as two telomere signals merged into one at the chromosome by immuno-FISH in metaphase spreads.Proteins related to the DNA damage response were detected using Western blot analysis.Apoptosis wasanalyzed using flow cytometry and Western blot.Results:The presence of 6-thio-dG increased the radio sensitivity of H1299 and A549 cells(P<0.05),but had no effect on the normal human lung fibroblast line,MRC5.6-thio-dG pretreatment significantly reduced the clonogenic potential induced byγ-ray irradiation and aggravated genomic DNA and telomeric DNA damage(P<0.05).In addition,6-thio-dG pretreatment effectively increasedγ-ray irradiation induced telomere dysfunction(P<0.05),resulting in disruption of chromosome stability and inhibition of the ATM pathway,thereby impairing genomic DNA and telomeric DNA repair,which was closely associated with enhanced drug-mediated radiation-induced apoptosis.Conclusions:6-thio-dG increases the radiosensitivity of NSCLC by inhibiting ATM and inducing telomere dysfunction,which can potentially be used as a strategy for radiotherapy for NSCLC. | Nan Wei Qian Li Shaopeng Chen Shengmin Xu Lijun Wu | 2022 | Radiation Medicine and Protection2022，3，2： | 0 |
| 11 | Geometric structures,electronic characteristics,stabilities,catalytic activities,and descriptors of graphene-based single-atom catalysts显示文摘Single-atom catalysts(SACs)have been a research hotspot due to their high catalytic activity,selectivity,and atomic utilization rates.However,the theoretical research of SACs is relatively fragmented,which restricts further understanding of SAC stability and activity.To address this issue,we report our analysis of the geometric structures,electronic characteristics,stabilities,catalytic activities,and descriptors of 132 graphene-based singleatom catalysts(M/GS)obtained from density functional theory calculations.Based on the calculated formation and binding energies,a stability map of M/GS was established to guide catalyst synthesis.The effects of metal atoms and support on the charge of metal atoms are discussed.The catalytic activities of M/GS in both nitrogen and oxygen reduction reactions are predicted based on the calculated magnetic moment and the adsorption energy.Combined with the electronegativity and d-band center,a two-dimensional descriptor is proposed to predict the O adsorption energy on M/GS.More importantly,this theoretical study provides predictive guidance for the preparation and rational design of highly stable and active single-atom catalysts using nitrogen doping on graphene. | Weijie Yang Shaopeng Xu Kai Ma Chongchong Wu Ian D.Gates Xunlei Ding Weihua Meng Zhengyang Gao | 2020 | Nano Materials Science2020，2，2： | 0 |
| 12 | Significant discrepancies of land surface daily net radiation among ten remotely sensed and reanalysis products显示文摘Land surface all-wave net radiation(R_(n))is crucial in determining Earth’s climate by contributing to the surface radiation budget.This study evaluated seven satellite and three reanalysis long-term land surface R_(n)products under different spatial scales,spatial and temporal variations,and different conditions.The results showed that during 2000-2018,Global Land Surface Satellite Product(GLASS)-Moderate Resolution Imaging Spectroradiometer(MODIS)performed the best(RMSE=25.54 Wm^(-2),bias=-1.26 Wm^(-2)),followed by ERA5(the fifth-generation of European Centre for Medium-Range Weather Forecast Reanalysis)(RMSE=32.17 Wm^(-2),bias=-4.88 Wm^(-2))and GLASS-AVHRR(Advanced Very-High-Resolution Radiometer)(RMSE=33.10 Wm^(-2),bias=4.03 Wm^(-2)).During 1983-2018,GLASS-AVHRR and ERA5 ranked top and performed similarly,with RMSE values of 31.70 and 33.08 Wm^(-2)and biases of-4.56 and 3.48 Wm^(-2),respectively.The averaged multi-annual mean R_(n)over the global land surface of satellite products was higher than that of reanalysis products by about 10~30 Wm^(-2).These products differed remarkably in long-term trends variations,particularly pre-2000,but no significant trends were observed.Discrepancies were more frequent in satellite data,while reanalysis products showed smoother variations.Large discrepancies were found in regions with high latitudes,reflectance,and elevation which could be attributed to input radiative components,meteorological variables(e.g.,cloud properties,aerosol optical thickness),and applicability of the algorithms used.While further research is needed for detailed insights. | Xiuwan Yin Bo Jiang Shunlin Liang Shaopeng Li Xiang Zhao Qian Wang Jianglei Xu Jiakun Han Hui Liang Xiaotong Zhang Qiang Liu Yunjun Yao Kun Jia Xianhong Xie | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
