| 1 | Overview of Mechanism and Mitigation Measures on Multi-frequency Oscillation Caused by Large-scale Integration of Wind Power显示文摘In recent years,the large-scale integration of re-newable energy sources represented by wind power and the widespread application of power electronic devices in power systems have led to the emergence of multi-frequency oscillation problems covering multiple frequency segments,which seriously threaten system stability and restrict the accommodation of renewable energy.The oscillation problems related to renewable energy integration have become one of the most popular topics in the field of wind power integration and power system stability research.It has received extensive attention from both academia and industries with many promising research results achieved to date.This paper first analyzes several typical multi-frequency oscillation events caused by large-scale wind power integration in domestic and foreign projects,then studies the multi-frequency oscillation problems,including wind turbine’s shafting torsional oscillation,sub/super-synchronous oscillation and high frequency resonance.The state of the art is systematically summarized from the aspects of oscillation mechanism,analysis methods and mitigation measures,and the future research directions are explored. | Yongning Chi Bingjie Tang Jiabing Hu Xinshou Tian Haiyan Tang Yan Li Sujuan Sun Lei Shi Lei Shuai | 2019 | CSEE Journal of Power and Energy Systems2019，5，4： | 23 |
| 2 | Genetic analysis and gene mapping of a narrow leaf mutant in rice (Oryza sativa L.)显示文摘A narrow leaf mutant was obtained after T-DNA transformation conducted on a rice variety Zhonghua 11. Several abnormal morphological characteristics, including semi-dwarf, delayed flowering time, narrow and inward rolling leaves, and lower seed-setting, were observed. The rate of net photosynthesis (un-der saturate light) of flag leaves in the mutant was significantly lower than that of the wild type. More-over, the leaf transpiration rate and stomatal conductance in the mutant flag leaf were lower than those of the wild type at the grain filling stage. It was found that the mutant phenotype was not caused by the T-DNA insertion. Genetic analysis showed that the mutant was controlled by a single recessive gene, designated as nal3(t). A genetic linkage map was constructed using a large F2 mapping population de-rived from a cross between nal3(t) and an indica variety Longtefu B with 6 polymorphic markers on chromosome 12 identified from 366 SSR markers by the BAS method. Gene nal3(t) was mapped be-tween the markers RM7018 and RM3331. Fine mapping of nal3(t) locus was conducted with 22 newly developed STS markers based on the sequence diversity around the region harboring nal3(t) between Nipponbare and 93-11, and nal3(t) was finally mapped to a 136-kb region between the STS markers NS10 and RH12-8. | WANG DeKai LIU HeQin LI KeLei LI SuJuan TAO YueZhi | 2009 | Chinese Science Bulletin2009，54，5： | 19 |

| 4 | Anti-diabetic effects and mechanisms of action of a Chinese herbal medicine preparation JQ-R in vitro and in diabetic KKAy mice显示文摘Refined-JQ(JQ-R) is a mixture of refined extracts from Coptis chinensis(Ranunculaceae),Astragalus membranaceus(Leguminosae) and Lonicera japonica(Caprifoliaceae), the three major herbs of Jin Qi-Jiang Tang tablet, a traditional Chinese medicine(TCM) formula. The mechanisms by which JQ-R regulates glucose metabolism and improves insulin sensitivity were studied in type 2 diabetic KK^(Ay)mice and insulin-resistant L6 myotubes. To investigate the mechanisms by which JQ-R improves insulin sensitivity, a model of insulin-resistant cells induced with palmitic acid(PA) was established in L6 myotubes. Glucose uptake and expression of factors involved in insulin signaling, stress, and inflammatory pathways were detected by immunoblotting. JQ-R showed beneficial effects on glucose homeostasis and insulin resistance in a euglycemic clamp experiment and decreased fasting insulin levels in diabetic KK^(Ay)mice. JQ-R also improved the plasma lipid profiles. JQ-R directly increased the activity of superoxide dismutase(SOD) and decreased malondialdehyde(MDA) as well as inducible nitric oxide synthase(iNOS) levels in insulin-resistant L6 cells, and elevated the insulin-stimulated glucose uptake with upregulated phosphorylation of AKT. The phosphorylation levels of nuclear factor kappa B(NF-κB p65), inhibitor of NF-κB(IκBα), c-Jun N-terminal kinase(JNK1/2) and extracellular-signal-regulated kinases(ERK1/2) were also changed after JQ-R treatment compared with the control group. Together these findings suggest that JQ-R improved glucose and lipid metabolism in diabetic KK^(Ay)mice. JQ-R directly enhanced insulin-stimulated glucose uptake in insulin-resistant myotubes with improved insulin signalling and inflammatory response and oxidative stress. JQ-R could be a candidate to achieve improved glucose metabolism and insulin sensitivity in type 2 diabetes mellitus. | Quan Liu Shuainan Liu Lihui Gao Sujuan Sun Yi Huan Caina Li Yue Wang Nan Guo Zhufang Shen | 2017 | Acta Pharmaceutica Sinica B2017，7，4： | 11 |
| 5 | An assessment of the effectiveness and impact of electrokinetic remediation for pyrene-contaminated soil显示文摘The effectiveness of electrokinetic remediation for pyrene-contaminated soil was investigated by an anode–cathode separated system using a salt bridge. The applied constant voltage was24 V and the electrode gap was 24 cm. Two types of soil(sandy soil and loam soil) were selected because of their different conductive capabilities. The initial concentrations of pyrene in these soil samples were 261.3 mg/kg sandy soil and 259.8 mg/kg loam soil. After treatment of the sandy soil and loam soil for seven days, 56.8% and 20.1% of the pyrene had been removed respectively. Under the same power supply voltage, the removal of the pollutant from the sandy soil was greater than that from the loam soil, due to the higher current and lower p H. Further analysis revealed that the effectiveness of electrokinetic remediation was affected by the energy expenditure, and was associated with changes in soil properties. | Sujuan Xu Shuhai Guo Bo Wu Fengmei Li Tingting Li | 2014 | Journal of Environmental Sciences2014，26，11： | 11 |

| 9 | TCP7 functions redundantly with several Class Ⅰ TCPs and regulates endoreplication in Arabidopsis显示文摘TCP(TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR) proteins, a family of plantspecific transcription factors, play important roles in many developmental processes. However, genetic and functional redundancy among class I TCP limits the analysis of their biological roles. Here, we identified a dominantnegative mutant of Arabidopsis thaliana TCP7 named leaf curling-upward(lcu), which exhibits smaller leaf cells and shorter hypocotyls than the wild type, due to defective endoreplication. A septuple loss-of-function mutant of TCP7, TCP8, TCP14, TCP15, TCP21, TCP22, and TCP23 displayed similar developmental defects to those of lcu.Genome-wide RNA-sequencing showed that lcu and the septuple mutant share many misexpressed genes.Intriguingly, TCP7 directly targets the CYCLIN D1;1 (CYCD1;1) locus and activates its transcription. We determined that the C-terminus of TCP7 accounts for its transcriptional activation activity. Furthermore, the mutant protein LCU exhibited reduced transcriptional activation activity due to the introduction of an EAR-like repressive domain at its C-terminus. Together, these observations indicate that TCP7 plays important roles during leaf and hypocotyl development, redundantly, with at least six class I TCPs, and regulates the expression of CYCD1;1 to affect endoreplication in Arabidopsis. | Guofang Zhang Hongtao Zhao Chunguang Zhang Xiaoyun Li Yuanyuan Lyu Dongmei Qi Yanwei Cui Lin Hu Zhenjie Wang Zheng Liang Sujuan Cui | 2019 | Journal of Integrative Plant Biology2019，61，11： | 5 |

| 11 | Acupuncture for cerebral ischemia/reperfusion injury Does it reduce the inflammatory reaction?显示文摘BACKGROUND:Nuclear factor-κB (NF-κB), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) in brain tissue can participate in inflammatory reactions after cerebral ischemia.Acupuncture treatment for acute cerebral ischemia produces abnormal protein expression.OBJECTIVE:To investigate the effects of acupuncture on NF-κB, ICAM-1, and VCAM-1 mRNA and protein expression in the brain tissue of rats with cerebral ischemia/reperfusion injury.DESIGN, TIME AND SETTING:Randomized, controlled, animal experiments were performed at the Laboratory of Department of Neurosurgery, Xiangya Hospital, Central South University, China between December 2008 and October 2009.MATERIALS:Rabbit anti-NF-κB polyclonal antibody, rabbit anti-ICAM-1 polyclonal antibody, and rabbit anti-VCAM-1 polyclonal antibody were purchased from Santa Cruz Biotechnology, USA.METHODS:A total of 46 healthy, Sprague Dawley rats were randomly assigned to sham surgery (n=10), model (n=12), acupuncture pretreatment (n=12), and acupuncture intervention (n=12) groups.Models of middle cerebral artery occlusion were established by right common carotid artery ligation.In the acupuncture pretreatment group, rats received acupuncture for 3 consecutive days, and then models were established.In the acupuncture intervention group, rats received acupuncture for 3 consecutive days at Waiguan (SJ 5), Sanyinjiao (SP 6), and Dazhui (DU 14) acupoints following model establishment.MAIN OUTCOME MEASURES:Somatosensory asymmetry and forelimb use asymmetry were tested, as well as NF-κB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex at 4, 12, 24, 48 and 72 hours following cerebral ischemia/reperfusion injury.RESULTS:Acupuncture improved neurological function and significantly decreased NF-κB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex of rats with cerebral ischemia/reperfusion injury (P<0.05).CONCLUSION:Acupuncture can improve neurological function, potentially via inhibition of NF-κB, ICAM-1, and VCAM-1 mRNA and protein expression in the frontal and parietal cortex of rats with cerebral ischemia/reperfusion injury. | Zhenyan Li Guangwei Zhong Sujuan Huang Yunsheng Liu Sue Wang Wei Li | 2010 | Neural Regeneration Research2010，5，14： | 4 |
| 12 | Characterization and molecular cloning of a serine hydroxymethyltransferase 1(OsSHM_1) in rice显示文摘Serine hydroxymethyltransferase(SHMT) is important for one carbon metabolism and photorespiration in higher plants for its participation in plant growth and development,and resistance to biotic and abiotic stresses. A rice serine hydroxymethyltransferase gene, Os SHM1, an ortholog of Arabidopsis SHM1, was isolated using map-based cloning. The osshm1 mutant had chlorotic lesions and a considerably smaller,lethal phenotype under natural ambient CO2 concentrations,but could be restored to wild type with normal growth under elevated CO2levels(0.5% CO2), showing a typical photorespiratory phenotype. The data from antioxidant enzymes activity measurement suggested that osshm1 was subjected to signi fi cant oxidative stress. Also, Os SHM1 was expressed in allorgans tested(root, culm, leaf, and young panicle) but predominantly in leaves. Os SHM1 protein is localized to the mitochondria. Our study suggested that molecular function of the Os SHM1 gene is conserved in rice and Arabidopsis. | Dekai Wang Heqin Liu Sujuan Li Guowei Zhai Jianfeng Shao Yuezhi Tao | 2015 | Journal of Integrative Plant Biology2015，57，9： | 3 |
| 13 | Analytical methods and environmental processes of nanoplastics显示文摘The degradation of plastic debris may result in the generation of nanoplastics(NPs).Their high specific surface area for the sorption of organic pollutions and toxic heavy metals and possible transfer between organisms at different nutrient levels make the study of NPs an urgent priority.However,there is very limited understanding on the occurrence,distribution,abundant,and fate of NPs in the environment,partially due to the lack of suitable techniques for the separation and identification of NPs from complex environmental matrices.In this review,we first overviewed the state-of-the-art methods for the extraction,separation,identification and quantification of NPs in the environment.Some of them have been successfully applied for the field determination of NPs,while some are borrowed from the detection of microplastics or engineered nanomaterials.Then the possible fate and transport of NPs in the environment are thoroughly described.Although great efforts have been made during the recent years,large knowledge gaps still exist,such as the relatively high detection limit of existing method failing to detect ultralow masses of NPs in the environment,and spherical polystyrene NP models failing to represent the various compositions of NPs with different irregular shapes,which needs further investigation. | Peng Li Qingcun Li Zhineng Hao Sujuan Yu Jingfu Liu | 2020 | Journal of Environmental Sciences2020，32，8： | 3 |
| 14 | Production of propene from 1-butene metathesis reaction on tungsten based heterogeneous catalysts显示文摘A new propene production route from 1-butene metathesis has been developed on heterogeneous 10WO3/Al2O3-HY catalysts with different HY contents.It is found that the catalysts play bi-functionally first for the isomerization of 1-butene to 2-butene and then for the cross-metathesis between 1-butene and 2-butene to propene and 2-pentene.The combination of HY zeolite and Al2O3 is prerequisite for the production of propene.The propene yield keeps increasing with the HY content in the range of 10-70 wt%,where 10WO3/Al2O3-70HY exhibits the highest propene yield.The MS-H2-TPR and MS-O2-TPO characterizations indicate that the increase of HY content in the catalysts weakens the interaction between W species and supports,whereas enhance the probability of coking on the metal species and acid sites. | Huijuan Liu Ling Zhang Xiujie Li Shengjun Huang Shenglin Liu Wenjie Xin Sujuan Xie Longya Xu | 2009 | Journal of Natural Gas Chemistry2009，18，3： | 3 |
| 15 | 1-Butene isomerization and metathesis over Mo/mordenite-alumina: Factors influencing product distribution and induction period显示文摘Effects of space velocity, reaction temperature and support acidity on product distribution and induction period in 1-butene isomerization and metathesis over Mo/mordenite-alumina were investigated. As revealed by the catalytic performance results, induction period and objective product were closely related to the reaction conditions. Lower space velocity led to longer induction period and higher propene yield. The optimal reaction temperature for propene production is around 150C and it shifted to 100C for ethene production. 1-Butene auto-metathesis predominated in the reaction network if the support with lower degree of sodium exchanged. And propene gradually became the dominant product upon increasing the support sodium exchange degree. 6Mo/H 100 Na 0 M-30Al catalyst with a support of full sodium exchange degree exhibited the highest propene yield. | Xiujie Li Xiangxue Zhu Dazhou Zhang Fucun Chen Peng Zeng Shenglin Liu Sujuan Xie Longya Xu | 2013 | Journal of Energy Chemistry2013，22，1： | 3 |
| 16 | Two-dimensional TiO_(2)(001)nanosheets as an effective photo-assisted recyclable sensor for the electrochemical detection of bisphenol A显示文摘Electrochemical detection is an efficient method for the detection of Bisphenol A(BPA).Herein,a sensitive photo-electrochemical sensor based on two-dimensional(2 D)TiO_(2)(001)nanosheets was fabricated and then used for BPA electrochemical detection.Upon light irradiation,the 2 D TiO_(2)(001)nanosheets electrode provided a lower detection limit of BPA detection compared with an ambient electrochemical determination.The low detection limit is^5.37 nmol/L(S/N=3).Furthermore,profiting from the photoelectric characteristics,the 2 D TiO_(2)(001)nanosheets electrode exhibits a nice regeneration prope rty.After 45 min of light irradiation,the electrochemical signal was regenerated from14.7%to 82.9%of the original signal at the 6th cycle.This is attributed to the non-selective·OH mediation produced by the 2 D TiO_(2)(001)nanosheets mineralizing anodic polymeric products and resuming surface reactive sites.This investigation indicates that photo-assistance is an efficient method to improve the electrochemical sensor for detecting BPA in water environments. | Sujuan Hu Yingjian Yu Yu Guan Yanhuan Li Baoling Wang Mingshan Zhu | 2020 | Chinese Chemical Letters2020，31，10： | 3 |
| 17 | Cross metathesis of butene-2 and ethene to propene overMo/MCM-22-Al_2O_3 catalysts with different Al_2O_3 contents显示文摘A series of 3.0Mo/MCM-22-Al2O3 catalysts with γ-Al2O3 contents in the range of 0-100 wt%were prepared and applied in the metathesis reaction of ethene and butene-2.Addition of γ-Al2O3 did not affect the structure of MCM-22 zeolite as evidenced by XRD and N2 adsorption measurements.It was deduced from TPR experiments that γ-Al2O3 phase favored the formation of polymolybdate or multilayered Mo oxide,while more Al2(MoO4)3 species were generated over MCM-22 zeolites.Alumina content in the support was directly related to the metathesis activity of ethene and butene-2 to propene.Mo species with higher valence(Mo6+or Mo5+)contributed more to the excellent performance of catalyst than metallic Mo.The best catalyst activity and stability was obtained over 3.0Mo/(MCM-22-30%Al2O3)under the reaction condition of 1.0 MPa and 125℃ using N2 as the pretreatment gas. | Shenglin Liu Xiujie Li Wenjie Xin Sujuan Xie Peng Zeng Lixin Zhang Longya Xu | 2010 | Journal of Natural Gas Chemistry2010，19，5： | 2 |
| 18 | Channel Mismatches Correction in Time-Interleaved ADCs Based on Hybrid Filter Bank Reconstruction显示文摘Time-interleaved analog-to-digital converter(TIADC) is an efficient way to achieve higher sampling rate for medium-to-high resolution applications. The performance of a TIADC suffers from the mismatch errors among the sub-channels. This paper presents a method to estimate the channel mismatches using the sub-channels output data. The proposed method introduces an equivalent transfer function for each channel to model and estimate the mismatch errors. A Hybrid filter bank(HFB)structure is used to both model the TIADC and reconstruct the desired uniformly sampled sequence based on the perfect reconstruction conditions of the HFB system.A four-channel 12-bit 400 MHz TIADC has been implemented in hardware to verify the proposed calibration method. The measured results show that the Spuriousfree dynamic range(SFDR) can be improved up to 74 d B after being corrected with 64-tap Finite-impulse response(FIR) filters. | LIU Sujuan ZHUO Li JIANG Wenshu ZHANG Meihui | 2014 | Chinese Journal of Electronics2014，23，1： | 2 |
