| 1 | Multi-energy Storage System Model Based on Electricity Heat and Hydrogen Coordinated Optimization for Power Grid Flexibility显示文摘Based on decreasing the flexibility of the power grid through the integration of large-scale renewable energy,a multi-energy storage system architectural model and its coor-dination operational strategy with the same flexibility as in the pumped storage power station and battery energy storage system(BESS)are studied.According to the new energy fluctuation characteristics and the different peak valley parameters in the power grid,this paper proposes a electricity heat hydrogen multi-energy storage system(EHH-MESS)and its coordination and optimization operational model to reduce the curtailment of wind power and photovoltaic(PV)to the power grid and improve the flexibility of the power grid.Finally,this paper studied the simulation model of an energy storage optimization control strategy after the multi-energy storage system is connected to the distribution networks,and analyzed three operational modes of the multi-energy storage system.The simulation results show that the EHH-MESS proposed in this paper has a better power grid regulation flexibility and economy,and can be used to replace the battery energy storage system based on MATLAB. | Yun Teng Zedi Wang Yan Li Qian Ma Qian Hui Shubin Li | 2019 | CSEE Journal of Power and Energy Systems2019,5,2: | 38 |
| 2 | Litterfall production and nutrient return in different-aged Chinese fir(Cunninghamia lanceolata) plantations in South China显示文摘The amounts of litter produced and nutrients returned play a fundamental role in the productivity and biogeochemical and nutrient cycling of forest ecosystems.We monitored annual litterfall production, nutrient return,and monthly dynamics over a one-year period in Chinese fir plantations aged 10, 22, and 34 years. Our objective was to quantify litterfall and nutrient return over a complete harvest rotation of Chinese fir. Annual litterfall production increased with stand age and was recorded as(3,294.6 ± 360.4),(3,733.9 ± 211.2), and(4,876.1 ± 212.8) kg ha-1a-1in stands aged 10, 22 and 34 years, respectively. Total litter production was significantly greater in the stand aged34 years than in the stand aged 10 years(p \ 0.05). With the exception of miscellaneous components, needle litterfall constituted the highest proportion(27.5–43.6 %), followed by branches/twigs(9.5–16.6 %). In all three plantations,annual total nutrient return to soil was in the order of C(1,119.95–2,709.05 kg ha-1a-1) [ N(39.32–62.04 kg ha-1a-1) [ K(15.95–22.44 kg ha-1a-1) [ P(1.30–1.63 kg ha-1a-1). C, N, K and P input to soil was significantly lower in the 10-year-old stand in comparison to the 22- and34-year-old stands(p \ 0.05). Litterfall production and nutrient return(C, N and K) followed similar patterns, and C and N input to soil was significantly related to litterfall production(needle, branch and total litterfall). C, N, P and K input to soil and total litterfall production were mainly driven by needle litterfall. | Lili Zhou Addo-Danso Daniel Shalom Pengfei Wu Shubin Li Yayun Jia Xiangqing Ma | 2015 | Journal of Forestry Research2015,26,1: | 32 |
| 3 | Cardamonin from a medicinal herb protects against LPS-induced septic shock by suppressing NLRP3 inflammasome显示文摘Aberrant activation of NLRP3 inflammasome has been implicated in the pathogenesis of diverse inflammation-related diseases, and pharmacological molecules targeting NLRP3 inflammasome are of considerable value to identifying potential therapeutic interventions. Cardamonin(CDN), the major active ingredient of the traditional Chinese medicinal herb Alpinia katsumadai, has exerted an excellent anti-inflammatory activity, but the mechanism underlying this role is not fully understood. Here, we show that CDN blocks canonical and noncanonical NLRP3 inflammasome activation triggered by multiple stimuli. Moreover, the suppression of CDN on inflammasome activation is specific to NLRP3, not to NLRC4 or AIM2 inflammasome. Besides, the inhibitory effect is not dependent on the expression of NF-κB-mediated inflammasome precursor proteins. We also demonstrate that CDN suppresses the NLRP3 inflammasome through blocking ASC oligomerization and speckle formation in a dose-dependent manner.Importantly, CDN improves the survival of mice suffering from lethal septic shock and attenuates IL-1βproduction induced by LPS in vivo, which is shown to be NLRP3 dependent. In conclusion, our results identify CDN as a broad-spectrum and specific inhibitor of NLRP3 inflammasome and a candidate therapeutic drug for treating NLRP3 inflammasome-driven diseases. | Zhilei Wang Guang Xu Yuan Gao Xiaoyan Zhan Nan Qin Shubin Fu Ruisheng Li Ming Niu Jiabo Wang Youping Liu Xiaohe Xiao Zhaofang Bai | 2019 | Acta Pharmaceutica Sinica B2019,9,4: | 19 |

| 5 | Bavachin enhances NLRP3 inflammasome activation induced by ATP or nigericin and causes idiosyncratic hepatotoxicity显示文摘Psoraleae Fructus(PF)is a well-known traditional herbal medicine in China,and it is widely used for osteoporosis,vitiligo,and other diseases in clinical settings.However,liver injury caused by PF and its preparations has been frequently reported in recent years.Our previous studies have demonstrated that PF could cause idiosyncratic drug-induced liver injury(IDILI),but the mechanism underlying its hepatotoxicity remains unclear.This paper reports that bavachin isolated from PF enhances the specific stimuli-induced activation of the NLRP3 inflammasome and leads to hepatotoxicity.Bavachin boosts the secretion of IL-ip and caspase-1 caused by ATP or nigericin but not those induced by poly(I:C),monosodium urate crystal,or intracellular lipopolysaccharide.Bavachin does not affect AIM2 or NLRC4 inflammasome activation.Mechanistically,bavachin specifically increases the production of nigericin-induced mitochondrial reactive oxygen species among the most important upstream events in the activation of the NLRP3 inflammasome.Bavachin increases the levels of aspartate transaminase and alanine aminotransferase in serum and hepatocyte injury accompanied by the secretion of IL-ip via a mouse model of lipopolysaccharide-mediated susceptibility to IDILI.These results suggest that bavachin specifically enhances the ATP-or nigericin-induced activation of the NLRP3 inflammasome.Bavachin also potentially contributes to PF-induced idiosyncratic hepatotoxicity.Moreover,bavachin and PF should be evaded among patients with diseases linked to the ATP-or nigericin-mediated activation of the NLRP3 inflammasome,which may be a dangerous factor for liver injury. | Nan Qin Guang Xu Yan Wang Xiaoyan Zhan Yuan Gao Zhilei Wang Shubin Fu Wei Shi Xiaorong Hou Chunyu Wang Ruisheng Li Yan Liu Jiabo Wang Haiping Zhao Xiaohe Xiao Zhaofang Bai | 2021 | Frontiers of Medicine2021,15,4: | 9 |
| 6 | Inheritance of Perpetual Blooming in Rosa chinensis ‘Old Blush'显示文摘Perpetual blooming is one of the most important biological and economical traits in modern rose, while the genetic basis underlining the control of this trait is poorly investigated. With an aim in dissecting the genetic determinism of perpetual blooming, we developed six rose populations(OB, W, F1, F2, BC1 OB and BC1W) derived from a WOB population [interspecific diploid hybridization between Rosa chinensis ‘Old Blush'(OB) and R. wichuriana ‘Basye's Thornless'(W)]. Perpetual blooming is absent both in a F1 population with 296 individuals and a BC1 W population(W as the backcross parent) with 150 individuals. However, the perpetual blooming trait showed a typical 3︰1 segregation in a backcross population BC1 OB with OB as the backcross parent. In this population with 300 individuals, 83 plants had the perpetual blooming phenotype while the other 217 featured non-perpetual blooming, indicating that the perpetual blooming trait is very likely controlled by two recessive genes in R. chinensis(rpb1 and rpb2). These genetic data suggest that the inheritance of rose perpetual blooming may be controlled by a complex mechanism. | LI Shubin ZHOU Ningning ZHOU Qing YAN Huijun JIAN Hongying WANG Qigang CHEN Min QIU Xianqin ZHANG Hao WANG Shufang LI Shufa TANG Kaixue | 2015 | Horticultural Plant Journal2015,1,2: | 9 |

| 8 | A green method to synthesize flowerlike Fe(OH)3 microspheres for enhanced adsorption performance toward organic and heavy metal pollutants显示文摘Dyestuffs and heavy metal ions in water are seriously harmful to the ecological environment and human health.Three-dimensional(3 D) flowerlike Fe(OH)_3 microspheres were synthesized through a green yet low-cost injection method,for the removal of organic dyes and heavy metal ions.The Fe(OH)_3 microspheres were characterized by thermal gravimetric analysis(TGA),Fourier transform infrared(FT-IR),and transmission electron microscopy(TEM) techniques.The adsorption kinetics of Congo Red(CR) on Fe(OH)_3 microspheres obeyed the pseudo-second-order model.Cr^(6+) and Pb^(2+) adsorption behaviors on Fe(OH)_3 microspheres followed the Langmuir isotherm model.The maximum adsorption capacities of the synthesized Fe(OH)_3 were 308,52.94,and 75.64 mg/g for CR,Cr^(6+),and Pb^(2+) respectively.The enhanced adsorption performance originated from its surface properties and large specific surface area of 250 m^2/g.The microspheres also have excellent adsorption stability and recyclability.Another merit of the Fe(OH)_3 material is that it also acts as a Fenton-like catalyst.These twin functionalities(both as adsorbent and Fenton-like catalyst) give the synthesized Fe(OH)_3 microspheres great potential in the field of water treatment. | Xiaole Zhao Yingehun Su Shubin Li Yajun Bi Xiaojun Han | 2018 | Journal of Environmental Sciences2018,30,11: | 7 |
| 9 | An efficient and fast polarity optimization approach for mixed polarity Reed-Muller logic circuits显示文摘尽管基因算法广泛地在混合极性芦苇思考(MPRM ) 逻辑电路的极性优化被使用了,很少研究考虑了极性变换顺序。以便改进 MPRM 逻辑电路的极性优化的效率,我们就极性变换顺序而言建议一条有效、快的极性优化途径(FPOA ) 。第一,在 FPOA 后面的主要想法是那等评估的极性集合的最好的极性变换顺序被使用建议混合基因算法(HGA ) 获得;第二,每在极性集合的极性根据 HGA 获得的最好的极性变换顺序被变换。我们的建议 FPOA 在 C 被实现,比较分析为 MCNC 基准电路被介绍了。试验性的结果证明为有更多的变量的电路, FPOA 在与极性变换顺序和改进极性优化与启发式的技术接近疏忽的传统的极性优化途径相比改进 MPRM 逻辑电路的极性优化的效率是高度有效的。 | Zhenxue HE Limin XIAO Fei GU Tongsheng XIA Shubin SU Zhisheng HUO Rong ZHANG Longbing ZHANG Li RUAN Xiang WANG | 2017 | Frontiers of Computer Science2017,11,4: | 6 |
| 10 | Crustal structures of the Weihe graben and its surroundings from receiver functions显示文摘We use 15 seismic stations,crossing the Qinling orogen(QO),Weihe graben(WG)and Ordos block(OB),to study the crustal structures by receiver functions(RFs)methods.The results show quite a difference in crustal structures and materials of three tectonic units(orogenic belt,extentional basin and stable craton).The average crustal thickness in the northern QO is 37.8 km,and Poisson ratio is 0.247,which indicates the increase of felsic materials in QO.In the southern OB,the average crustal thickness is 39.2 km and Poisson ratio is 0.265.Comparatively high value of Poisson ratio is related with old crystallized base in the lower crust and shallow sediments.The artificial RFs reveal that low-velocity and thick sediments have a significant effect on phases of the Mohorovi i discontinuity(Moho).As a result,the Moho phases in WG are tangled.S-wave velocity(VS)inversion shows that there are shallow sediment layers with 4–8 km’s thickness and high velocity zones in the middle-lower crust in WG.Complex Moho structure and high velocity zone may have been induced by the activities of the Weihe faults series. | XU ShuBin MI Ning XU MingJie WANG LiangShu LI Hua YU DaYong | 2014 | Science China Earth Sciences2014,57,2: | 5 |
| 11 | MOF-derived ZnCo_2O_4/C wrapped on carbon fiber as anode materials for structural lithium-ion batteries显示文摘To meet the requirements for the mechanical and electrochemical performance for carbon fiber-based (CF-based) composites in the structural lithium ion batteries (SLIBs) application, better CF-Based composites are urgently needed. Herein, we report a novel composite metal organic framework (MOF)-derived ZnCo_2 O_4/C@carbon fiber via a facile method and subsequent annealing treatment. In this anode,the nano ZnCo_2 O_4/C coatings wrapped on the surface of CF provide more active sites for electrode reactions and the thin carbon layers give the additional protection. For this material, after 100 cycles, it exhibits excellent cycling stability including high reversible capacity of 463 mAh/g at 50 mA/g, which increases 201% than that of the CF. Thus, this structural anode material exhibits enhanced capacity, high initial columbic efficiency. | Huagen Li Shubin Wang Mengjie Feng Jiping Yang Boming Zhang | 2019 | Chinese Chemical Letters2019,30,2: | 4 |
| 12 | Review of local mean decomposition and its application in fault diagnosis of rotating machinery显示文摘Rotating machinery is widely used in the industry.They are vulnerable to many kinds of damages especially for those working under tough and time-varying operation conditions.Early detection of these damages is important,otherwise,they may lead to large economic loss even a catastrophe.Many signal processing methods have been developed for fault diagnosis of the rotating machinery.Local mean decomposition(LMD)is an adaptive mode decomposition method that can decompose a complicated signal into a series of mono-components,namely product functions(PFs).In recent years,many researchers have adopted LMD in fault detection and diagnosis of rotating machines.We give a comprehensive review of LMD in fault detection and diagnosis of rotating machines.First,the LMD is described.The advantages,disadvantages and some improved LMD methods are presented.Then,a comprehensive review on applications of LMD in fault diagnosis of the rotating machinery is given.The review is divided into four parts:fault diagnosis of gears,fault diagnosis of rotors,fault diagnosis of bearings,and other LMD applications.In each of these four parts,a review is given to applications applying the LMD,improved LMD,and LMD-based combination methods,respectively.We give a summary of this review and some future potential topics at the end. | LI Yongbo SI Shubin LIU Zhiliang LIANG Xihui | 2019 | Journal of Systems Engineering and Electronics2019,30,4: | 4 |
| 13 | Generation of tooth-like structures from integration-free human urine induced pluripotent stem cells显示文摘Background:Tooth is vital not only for a good smile,but also good health.Yet,we lose tooth regularly due to accidents or diseases.An ideal solution to this problem is to regenerate tooth with patients’own cells.Here we describe the generation of tooth-like structures from integration-free human urine induced pluripotent stem cells(ifhU-iPSCs).Results:We first differentiated ifhU-iPSCs to epithelial sheets,which were then recombined with E14.5 mouse dental mesenchymes.Tooth-like structures were recovered from these recombinants in 3 weeks with success rate up to 30%for 8 different iPSC lines,comparable to H1 hESC.We further detected that ifhU-iPSC derived epithelial sheets differentiated into enamel-secreting ameloblasts in the tooth-like structures,possessing physical properties such as elastic modulus and hardness found in the regular human tooth.Conclusion:Our results demonstrate that ifhU-iPSCs can be used to regenerate patient specific dental tissues or even tooth for further drug screening or regenerative therapies. | Jinglei Cai Yanmei Zhang Pengfei Liu Shubin Chen Xuan Wu Yuhua Sun Ang Li Ke Huang Rongping Luo Lihui Wang Ying Liu Ting Zhou Shicheng Wei Guangjin Pan Duanqing Pei | 2013 | Cell Regeneration2013,2,1: | 4 |
| 14 | Characterizing optical dipole trap via fluorescence of trapped cesium atoms显示文摘Optical dipole trap (ODT) is becoming an important tool of manipulating neu- tral atoms. In this paper ODT is realized with a far-off resonant laser beam strongly fo- cused in the magneto-optical trap (MOT) of cesium atoms. The light shift is measured by simply monitoring the fluorescence of the atoms in the magneto-optical trap and the opti- cal dipole trap simultaneously. The advantages of our experimental scheme are discussed, and the effect of the beam waist and power on the potential of dipole trap as well as heating rate is analyzed. | LIU Tao GENG Tao YAN Shubin LI Gang ZHANG Jing WANG Junmin PENG Kunchi ZHANG Tiancai | 2006 | Science China(Physics,Mechanics & Astronomy)2006,49,3: | 4 |
| 15 | The clock system for LHAASO WCDA based on reduced White Rabbit显示文摘Due to the large scale of Water Cherenkov Detector Array in Large High Altitude Air Shower Observatory, the frontend digitization is imperative.Thus a clock distribution system is desired,which broadcasts the synchronous clock signals with low jitter to the frontend electronics distributed in the field of 90 000 m^2.The White Rabbit protocol provides an option,which has been approved to achieve sub-ns accuracy and ps jitter in the synchronization of around 1 000 nodes in the order of 10 km.But the hierarchy of the original is too complex for Large High Altitude Air Shower Observatory application.Thus we proposed a reduced scheme based on the White Rabbit protocol.The validation circuit shows that the clock skew due to the fiber length difference can be adjusted to less than 25 ps and the clock jitter is less than 62 ps. | LI Cheng LIU Shubin SHANG Linfeng CAO Ping AN Qi | 2012 | Nuclear Science and Techniques2012,23,4: | 3 |

| 17 | Neural progenitor cells from human induced pluripotent stem cells generated less autogenous immune response显示文摘The breakthrough development of induced pluripotent stem cells(iPSCs)raises the prospect of patient-specific treatment for many diseases through the replacement of affected cells.However,whether iPSC-derived functional cell lineages generate a deleterious immune response upon auto-transplantation remains unclear.In this study,we differentiated five human iPSC lines from skin fibroblasts and urine cells into neural progenitor cells(NPCs)and analyzed their immunogenicity.Through co-culture with autogenous peripheral blood mononuclear cells(PBMCs),we showed that both somatic cells and iPSC-derived NPCs do not stimulate significant autogenous PBMC proliferation.However,a significant immune reaction was detected when these cells were co-cultured with allogenous PBMCs.Furthermore,no significant expression of perforin or granzyme B was detected following stimulation of autogenous immune effector cells(CD3+CD8 T cells,CD3+CD8+T cells or CD3 CD56+NK cells)by NPCs in both PBMC and T cell co-culture systems.These results suggest that human iPSC-derived NPCs may not initiate an immune response in autogenous transplants,and thus set a base for further preclinical evaluation of human iPSCs. | HUANG Ke LIU PengFei LI Xiang CHEN ShuBin WANG LiHui QIN Li SU ZhengHui HUANG WenHao LIU JuLi JIA Bei LIU Jie CAI JingLei PEI DuanQing PAN GuangJin | 2014 | Science China(Life Sciences)2014,57,2: | 3 |
| 18 | The geometric simulation and analysis of the blind growth fold in the overthrust belt of the southern section of the frontier Longmen Mt.during Late Triassic显示文摘The seismic profiles processed by high-resolution display that a blind growth fault-bend fold emerges in depth of seismic exploration area in Dayi in the southern section of the frontier Longmen Mt.This paper presents a detailed structural interpretation to seismic section,then describes the deformed geometry related to the pre-growth strata,the growth strata and the post-growth strata on both limbs of the fold.The computer geometric simulation,based on the model of fault-bend fold,is utilized to stimulate the geometry of the blind growth fold at different sedimentation rates in Dayi.These structural features are subsequently extracted and compared with the actual seismic reflection section.Our research suggests that a low angle overthrust formed during Late Triassic also appears in the southern section of the frontier Longmen Mt.The event of structure took place at the depositional stage of a portion of the middle and upper fourth member of Xujiahe Formation(T3x4),which corresponds to thrusting in the northern section of the frontier Longmen Mt.However,the thrusting displacement here is smaller than one of the northern section. | CHEN Wei YANG KeMing LI ShuBin JIAN GaoMing TANG Jin ZHAO Yiao SU Qian | 2009 | Chinese Science Bulletin2009,54,8: | 3 |
| 19 | Cyclical helping hands: seasonal tailwinds differentially affect migrating Oriental Storks (Ciconia boyciana) travel speed显示文摘Background:The Oriental Stork(Ciconia boyciana)breeds in southeastern Siberia and parts of northeast China,and winters mainly in southeast China.Although the autumn migration pattern of Oriental Storks has been previ-ously described,differences between spring and autumn migration travel speed in relation to wind assistance were unknown.Methods:Using GPS/GSM transmitters,we tracked the full migrations of 18 Oriental Storks during 2015-2018 to compare differences in autumn and spring migration patterns,and combined the satellite telemetry data with the National Center for Environmental Prediction Reanalysis data to explain the relationship between 850 mbar wind vec-tors and seasonal differences in travel speed.Results:Differences in tailwinds contributed to significant differences in daily average Oriental Storks travel speed in spring(258.11±64.8 km/day)compared to autumn(172.23±49.7 km/day,p<0.001).Storks stopped significantly more often in autumn than spring(1.78±1.1 versus 1.06±0.9,p<0.05),but stopover duration(15.52±12.4 versus 16.30±15.1 days,respectively,p=0.3)did not differ significantly.Tailwinds at 850 mbar pressure level(extracted from the National Center of Environmental Prediction Reanalysis data archive)significantly affected daily flying speed dur-ing spring and autumn migration.Tailwind conditions in spring(mean 4.40±5.6 m/s)were always more favourable than in autumn when they received no net benefit(0.48±5.6 m/s,p<0.001).Despite mean spring migration dura-tion being less than autumn(27.52±15.9 versus 32.77±13.4 days,p=0.17),large individual variation meant that this duration did not differ significantly from each other.Conclusions:For long distance migratory soaring birds(such as storks),relative duration of spring and autumn migration likely relates to the interaction between imperative for earliest arrival to breeding grounds and seasonal meteorological conditions experienced en route. | Shujuan Fan Qingshan Zhao Hongbin Li Baoguang Zhu Shubin Dong Yanbo Xie Lei Cao Anthony David Fox | 2020 | Avian Research2020,11,2: | 2 |
| 20 | Fast Cryomediated Dynamic Equilibrium Hydrolysates towards Grain Boundary-Enriched Platinum Scaffolds for Efficient Methanol Oxidation显示文摘Although platinum nanocrystals have been considered as potential electrocatalysts for methanol oxidation reaction(MOR)in fuel cells,the large-scale practical implementation has been stagnated by their limited abundance,easy poisoning,and low durability.Here,grain boundary-enriched platinum(GB-Pt)scaffolds are produced in large scale via facilely reducing fast cryomediated dynamic equilibrium hydrolysates of platinum salts.Such plentiful platinum grain boundaries are originated from the fast fusion of short platinum nanowires during reduction of the individually and homogeneously dispersed platinum intermediates.These grain boundaries can provide abundant active sites to efficiently catalyze MOR and meanwhile enable to oxidize the adsorbed poisonous CO during the electrocatalytic process.As a consequence,the as-synthesized GB-Pt scaffolds exhibit an impressively high mass activity of 1027.1 mA mgPt^(−1) for MOR,much higher than that of commercial Pt/C(345.2 mA mgPt^(−1)),as well as good stability up to 5000 cycles.We are confident that this synthetic protocol can be further extended to synthesize various grain boundary-enriched metal scaffolds with broad applications in catalysis. | Chao Zhang Huajie Huang Jianan Gu Zhiguo Du Bin Li Songmei Li Shubin Yang | 2019 | Research2019,,1: | 2 |
