| 1 | Altitude dependency of trends of daily climate extremes in southwestern China, 1961-2008显示文摘A total of 12 indices of temperature extremes and 11 indices of precipitation ex-tremes at 111 stations in southwestern China at altitudes of 285-4700 m were examined for the period 1961-2008. Significant correlations of temperature extremes and elevation in-cluded the trends of diurnal temperature range, frost days, ice days, cold night frequency and cold day frequency. Regional trends of growing season length, warm night frequency, coldest night and warmest night displayed a statistically significant positive correlation with altitude. These characteristics indicated the obvious warming with altitude. For precipitation extreme indices, only the trends of consecutive dry days, consecutive wet days, wet day precipitation and the number of heavy precipitation days had significant correlations with increasing alti-tude owing to the complex influence of atmospheric circulation. It also indicated the increased precipitation mainly at higher altitude areas, whereas the increase of extreme precipitation events mainly at lowers altitude. In addition, the clearly local influences are also crucial on climate extremes. The analysis revealed an enhanced sensitivity of climate extremes to ele-vation in southwestern China in the context of recent warming. | Li Zongxing He Yuanqing Theakstone, Wilfred H.

| 3 | Arabidopsis C3HC4-RING finger E3 ubiquitin ligase At AIRP4 positively regulates stress-responsive abscisic acid signaling显示文摘Degradation of proteins via the ubiquitin system is an important step in many stress signaling pathways in plants.E3 ligases recognize ligand proteins and dictate the high specificity of protein degradation, and thus, play a pivotal role in ubiquitination. Here, we identified a gene, named Arabidopsis thaliana abscisic acid(ABA)-insensitive RING protein 4(At AIRP4), which is induced by ABA and other stress treatments. At AIRP4 encodes a cellular protein with a C3HC4-RING finger domain in its C-terminal side, which has in vitro E3 ligase activity. Loss of At AIRP4 leads to a decrease in sensitivity of root elongation and stomatal closure to ABA, whereas overexpression of this gene in the T-DNA insertion mutant atairp4 effectively recovered the ABA-associated phenotypes. At AIRP4 overexpression plants were hypersensitive to salt and osmotic stresses during seed germination, and showed drought avoidance compared with the wild-type and atairp4 mutant plants. In addition, the expression levels of ABA- and droughtinduced marker genes in At AIRP4 overexpression plants were markedly higher than those in the wild-type and atairp4 mutant plants. Hence, these results indicate that At AIRP4 may act as a positive regulator of ABA-mediated drought avoidance and a negative regulator of salt tolerance in Arabidopsis. | Liang Yang Qiaohong Liu Zhibin Liu Hao Yang Jianmei Wang Xufeng Li Yi Yang | 2016 | Journal of Integrative Plant Biology2016，58，1： | 15 |

| 6 | Bioinspired mineralized collagen scaffolds for bone tissue engineering显示文摘Successful regeneration of large segmental bone defects remains a major challenge in clinical orthopedics,thus it is of important significance to fabricate a suitable alternative material to stimulate bone regeneration.Due to their excellent biocompatibility,sufficient mechanical strength,and similar structure and composition of natural bone,the mineralized collagen scaffolds(MCSs)have been increasingly used as bone substitutes via tissue engineering approaches.Herein,we thoroughly summarize the state of the art of MCSs as tissue-engineered scaffolds for acceleration of bone repair,including their fabrication methods,critical factors for osteogenesis regulation,current opportunities and challenges in the future.First,the current fabrication methods for MCSs,mainly including direct mineral composite,in-situ mineralization and 3D printing techniques,have been proposed to improve their biomimetic physical structures in this review.Meanwhile,three aspects of physical(mechanics and morphology),biological(cells and growth factors)and chemical(composition and cross-linking)cues are described as the critical factors for regulating the osteogenic feature of MCSs.Finally,the opportunities and challenges associated with MCSs as bone tissue-engineered scaffolds are also discussed to point out the future directions for building the next generation of MCSs that should be endowed with satisfactorily mimetic structures and appropriately biological characters for bone regeneration. | Zhengwei Li Tianming Du Changshun Ruan Xufeng Niu | 2021 | Bioactive Materials2021，6，5： | 9 |
| 7 | Potential and Suitability Evaluation of CO_2 Geological Storage in Major Sedimentary Basins of China,and the Demonstration Project in Ordos Basin显示文摘From 2010 to 2012, the China Geological Survey Center for Hydrogeology and Environmental Geology Survey(CHEGS) carried out the project 'Potential evaluation and demonstration project of CO2 Geological Storage in China'. During this project, we developed an evaluation index system and technical methods for the potential and suitability of CO2 geological storage based on China's geological conditions, and evaluated the potential and suitability of the primary basins for CO2 geological storage, in order to draw a series of regional scale maps(at a scale of 1:5000000) and develop an atlas of the main sedimentary basins in China. By using these tools, we delineated many potential targets for CO2 storage. We also built techniques and methods for site selection and the exploration and assessment of CO2 geological storage in deep saline aquifers. Furthermore, through cooperation with the China Shenhua Coal to Liquid and Chemical Co., Ltd., we successfully constructed the first coal-based demonstration project for CO2 geological storage in deep saline aquifers in the Yijinhuoluo Banner of Ordos in the Inner Mongolia Autonomous Region, which brought about the basic preliminary theories, techniques, and methods of geological CO2 storage in deep saline aquifers under China's geological conditions. | GUO Jianqiang WEN Dongguang ZHANG Senqi XU Tianfu LI Xufeng DIAO Yujie JIA Xiaofeng | 2015 | Acta Geologica Sinica(English Edition)2015，89，4： | 8 |

| 9 | Drogue detection for autonomous aerial refueling based on convolutional neural networks显示文摘Drogue detection is a fundamental issue during the close docking phase of autonomous aerial refueling(AAR). To cope with this issue, a novel and effective method based on deep learning with convolutional neural networks(CNNs) is proposed. In order to ensure its robustness and wide application, a deep learning dataset of images was prepared by utilizing real data of ‘‘Probe and Drogue' aerial refueling, which contains diverse drogues in various environmental conditions without artificial features placed on the drogues. By employing deep learning ideas and graphics processing units(GPUs), a model for drogue detection using a Caffe deep learning framework with CNNs was designed to ensure the method's accuracy and real-time performance. Experiments were conducted to demonstrate the effectiveness of the proposed method, and results based on real AAR data compare its performance to other methods, validating the accuracy, speed, and robustness of its drogue detection ability. | Wang Xufeng Dong Xinmin Kong Xingwei Li Jianmin Zhang Bo | 2017 | Chinese Journal of Aeronautics2017，30，1： | 6 |

| 11 | Partial cooperative spectrum sensing schedule in cognitive network显示文摘Cognitive radio has emerged as a promising technology for maximizing the utilization efficiency of the limited spectrum resources while accommodating the increasing amount of services and applications in wireless networks. One of the most important and critical components of the cognitive radio is spectrum sensing and accordingly, detection of primary users. Considering the hardware constraints existing in cognitive devices, based on the coarse estimation of channel occupancy, partial cooperative spectrum sensing with adaptive spectrum schedule scheme is proposed to increase the possibility to discover more spectrum opportunities promptly. Simulation results show the gain of sensing performance and the energy-saving feature of partial spectrum sensing. Special security scheme is designed to protect the reliability of sensing result from the false message attack. For the scenarios tested, the proposed scheme is shown to increase opportunities by up to 15 percent. | XU FangMin ZHENG XuFeng LI XiaoQiang ZHOU Zheng | 2009 | Science in China(Series F)2009，52，12： | 5 |
| 12 | The size of cell-free mitochondrial DNA in blood is inversely correlated with tumor burden in cancer patients显示文摘Circulating cell-free DNAs(cfDNAs)are fragmented DNA molecules released into the blood by cells.Previous studies have suggested that mitochondria-originated cfDNA fragments(mt-cfDNAs)in cancer patients are more fragmented than those from healthy controls.However,it is still unknown where these short mtcfDNAs originate,and whether the length of mt-cfDNAs can be correlated with tumor burden and cancer progression.In this study,we first performed whole-genome sequencing analysis(WGS)of cfDNAs from a human tumor cell line-xenotransplantation mouse model and found that mt-cfDNAs released from transplanted tumor cells were shorter than the mouse counterpart.We next analyzed blood cfDNA samples from hepatocellular carcinoma and prostate cancer patients and found that mt-cfDNA lengths were inversely related to tumor size as well as the concentration of circulating tumor DNA.Our study suggested that monitoring the size of mt-cfDNAs in cancer patients would be a useful way to estimate tumor burden and cancer progression. | Qin An Youjin Hu Qingjiao Li Xufeng Chen Jiaoti Huang Matteo Pellegrini Xianghong Jasmine Zhou Matthew Rettig Guoping Fan | 2019 | Precision Clinical Medicine2019，2，3： | 4 |
| 13 | A Method for Evaluating the Suitability of CO2 Geological Storage in Deep Saline Aquifers显示文摘This work established an evaluation index system based on a comprehensive analysis of those factors affecting the suitability of CO_2 geological storage.This evaluation index system includes three evaluation index layers of geological safety,storage scale and social economy,nine evaluation index sub-layers,and 28 evaluation index factors,and adopts the analytic hierarchy process(AHP)and index overlay methods.Taking the Xining Basin in northwest China as an example,we conducted comprehensive analysis of geological conditions and performed quantitative evaluation based on this evaluation index system,which indicates that the Shuangshu depression of the Xining Basin is comparatively suitable for CO_2 geological storage.It is suggested that this evaluation index system and the evaluation method proposed in this study are suitable for most continental sedimentary basins in China and should be widely applied. | LI Fucheng ZHANG Yang JIA Xiaofeng LI Xufeng JIA Xiaoleng GUO Shengxiu | 2016 | Acta Geologica Sinica(English Edition)2016，90，5： | 4 |
| 14 | Genome-wide dissection of segregation distortion using multiple inter-subspecific crosses in rice显示文摘Mendelian inheritance can ensure equal segregation of alleles from parents to offspring, which provides fundamental basis for genetics and molecular biology. Segregation distortion(SD) leads to preferential transmission of certain alleles from generation to generation. Such violation of Mendelian genetic principle is often accompanied by reproductive isolation and eventually speciation. Although SD is observed in a wide range of species from plants to animals, genome-wide dissection of such biased transmission of gametes is rare. Using nine inter-subspecific rice crosses, a genome-wide screen for SD loci is performed, which reveals 61 single-locus quantitative trait loci and 194 digenic interactions showing distorted transmission ratio, among which 24 new SD loci are identified. Biased transmission of alleles is observed in all nine crosses, suggesting that SD exists extensively in rice populations. 72.13% distorted regions are repeatedly detected in multiple populations, and the most prevalent SD hotspot that observed in eight populations is mapped to chromosome 3. Xian alleles are transmitted at higher frequencies than geng alleles in inter-subspecific crosses, which change the genetic composition of the rice populations. Epistatic interaction contributes significantly to the deviation of Mendelian segregation at the whole-genome level in rice, which is distinct from that in animals. These results provide an extensive archive for investigating the genetic basis of SD in rice, which have significant implications in understanding the reproductive isolation and formation of inter-subspecific barriers during the evolution. | Guangwei Li Jiye Jin Yan Zhou Xufeng Bai Donghai Mao Cong Tan Gongwei Wang Yidan Ouyang | 2019 | Science China(Life Sciences)2019，62，4： | 4 |
| 15 | Abscisic acid receptors maintain abscisic acid homeostasis by modulating UGT71C5 glycosylation activity显示文摘Uridine diphosphate-glucosyltransferases(UGTs)maintain abscisic acid(ABA)homeostasis in Arabidopsis thaliana by converting ABA to abscisic acid-glucose ester(ABA-GE).UGT71C5 plays an important role in the generation of ABA-GE.Abscisic acid receptors are crucial upstream components of the ABA signaling pathway,but how UGTs and ABA receptors function together to modulate ABA levels is unknown.Here,we demonstrated that the ABA receptors RCAR12/13 and UGT71 C5 maintain ABA homeostasis in Arabidopsis following rehydration under drought stress.Biochemical analyses show that UGT71C5 directly interacted with RCAR8/12/13 in yeast cells,and the interactions between UGT-71C5 and RCAR12/13 were enhanced by ABA treatment.Enzyme activity analysis showed that ABA-GE contents were significantly elevated in the presence of RCAR12 or RCAR13,suggesting that these ABA receptors enhance the activity of UGT71C5.Determination of the content of ABA and ABA-GE in Arabidopsis following rehydration under drought stress revealed that ABA-GE contents were significantly higher in Arabidopsis plants overexpressing RCAR12 and RCAR13 than in nontransformed plants and plants overexpressing RCAR11 following rehydration under drought stress.These observations suggest that RCAR12 and RCAR13 enhance the activity of UGT71C5 to glycosylate excess ABA into ABA-GE following rehydration under drought stress,representing a rapid mechanism for regulating plant growth and development. | Yanlin Ma Jing Cao Qiaoqiao Chen Jiahan He Zhibin Liu Jianmei Wang Xufeng Li Yi Yang | 2021 | Journal of Integrative Plant Biology2021，63，3： | 3 |
| 16 | In vitro immunomodulation of magnesium on monocytic cell toward anti-inflammatory macrophages显示文摘Biodegradable magnesium(Mg)has shown great potential advantages over current bone fixation devices and vascular scaffold technologies;however,there are few reports on the immunomodulation of corrosive Mg products,the micron-sized Mg particles(MgMPs).Human monocytic leukemia cell line THP-1 was set as the in vitro cell model to estimate the immunomodulation of MgMPs on cell proliferation,apoptosis,polarization and inflammatory reaction.Our results indicated highconcentration of Mg^2+ demoted the proliferation of the THP-1 cells and,especially,THP-1-derived macrophages,which was a potential factor that could affect cell function,but meanwhile,cell apoptosis was almost not affected by Mg^2+.In particular,the inflammation regulatory effects of MgMPs were investigated.Macrophages exposed to Mg^2+ exhibited down-regulated expressions of M1 subtype markers and secretions of pro-inflammatory cytokines,up-regulated expression of M2 subtype marker and secretion of anti-inflammatory cytokine.These results indicated Mg^2+ could convert macrophages from M0 to M2 phenotype,and the bioeffects of MgMPs on human inflammatory cells were most likely due to the Mg^2+-induced NF-jB activation reduction.Together,our results proved Mg^2+ could be used as a new anti-inflammatory agent to suppress inflammation in clinical applications,which may provide new ideas for studying the immunomodulation of Mg-based implants on human immune system. | Lei Sun Xiaoyu Li Menghan Xu Fenghe Yang Wei Wang Xufeng Niu | 2020 | Regenerative Biomaterials2020，7，4： | 3 |
| 17 | Rare earth elements and yttrium in ferromanganese deposits from the South China Sea:distribution,composition and resource considerations显示文摘Ferromanganese nodules and crusts contain relatively high concentration of rare earth elements(REE) and yttrium(REY),with a growing interest in exploitation as an alternative to land-based REY resources.On the basis of comprehensive geochemical approach,the abundance and distribution of REY in the ferromanganese nodules from the South China Sea are analyzed.The results indicate that the REY contents in ferromanganese deposits show a clear geographic regularity.Total REY contents range from 69.1×10^(–6) to 2 919.4×10^(–6),with an average value of 1 459.5×10^(–6).Especially,the enrichment rate of Ce content is high,accounting for almost 60% of the total REY.This REE enrichment is controlled mainly by the sorption of ferromanganese oxides and clay minerals in the nodules and crusts.Moreover,the total REY are higher in ferromanganese deposits of hydrogenous origin than of diagenetic origin.Finally,Light REE(LREE) and heavy REE(HREE) oxides of the ferromanganese deposits in the study area can be classified into four grades: non-enriched type,weakly enriched type,enriched type,and extremely enriched type.According to the classification criteria of rare earth resources,the Xisha and Zhongsha platform-central deep basin areas show a great potential for these rare earth metals. | ZHONG Yi CHEN Zhong GONZALEZ Francisco Javier ZHENG Xufeng LI Gang LUO Yun MO Aibin XU Antao WANG Shuhong | 2018 | Acta Oceanologica Sinica2018，37，7： | 3 |

| 19 | Thermal and luminescent properties of 2 μm emission in thulium-sensitized holmium-doped silicate-germanate glass显示文摘In this paper, we present the luminescent properties of Tm^(3+)∕Ho^(3+)co-doped new glass. A series of silicategermanate glass was prepared by the conventional melt-quenching method. In the Tm^(3+)∕Ho^(3+)co-doped silicategermanate glass, a strong emission of 2 μm originating from the Ho^(3+):~5I_7→~5I_8transition can be observed under conventional 808 nm pumping. The characteristic temperatures, structure, and absorption spectra have been measured. The radiative properties of Ho^(3+)in the prepared glass were calculated. The emission cross section of Ho^(3+)ions transition can reach 4.78 × 10^(-21)cm^2 around 2 μm, and the FWHM is as high as 153 nm. The energy transfer efficiency between Ho^(3+)and Tm^(3+)has a large value(52%), which indicates the Tm^(3+)∕Ho^(3+)co-doped silicategermanate glass is a suitable candidate for the 2 μm laser. Moreover, the energy transfer mechanism between Tm^(3+)and Ho^(3+)ions was investigated. | Rong Chen Ying Tian Bingpeng Li Xufeng Jing Junjie Zhang Shiqing Xu Hellmut Eckert Xianghua Zhang | 2016 | Photonics Research2016，4，6： | 2 |
