| 1 | Effect of C/N ratio,aeration rate and moisture content on ammonia and greenhouse gas emission during the composting显示文摘Gaseous emission (N2O,CH4 and NH3) from composting can be an important source of anthropogenic greenhouse gas and air pollution.A laboratory scale orthogonal experiment was conducted to estimate the effects of C/N ratio,aeration rate and initial moisture content on gaseous emission during the composting of pig faeces from Chinese Ganqinfen system.The results showed that about 23.9% to 45.6% of total organic carbon (TOC) was lost in the form of CO2 and 0.8% to 7.5% of TOC emitted as CH4.Most of the nitrogen was lost in the form of NH3,which account for 9.6% to 32.4% of initial nitrogen.N2O was also an important way of nitrogen losses and 1.5% to 7.3% of initial total nitrogen was lost as it.Statistic analysis showed that the aeration rate is the most important factor which could affect the NH3 (p=0.0189),CH4 (p=0.0113) and N2O (p=0.0493) emissions significantly.Higher aeration rates reduce the CH4 emission but increase the NH3 and N2O losses.C/N ratio could affect the NH3 (p=0.0442) and CH4 (p=0.0246) emissions significantly,but not the N2O.Lower C/N ratio caused higher NH3 and CH4 emissions.The initial moisture content can not influence the gaseous emission significantly.Most treatments were matured after 37 days,except a trial with high moisture content and a low C/N ratio. | Tao Jiang Frank Schuchardt Guoxue Li Rui Guo Yuanqiu Zhao | 2011 | Journal of Environmental Sciences2011,23,10: | 67 |
| 2 | Reentry trajectory optimization for hypersonic vehicle satisfying complex constraints显示文摘The reentry trajectory optimization for hypersonic vehicle(HV)is a current problem of great interest.Some complex constraints,such as waypoints for reconnaissance and no-fly zones for threat avoidance,are inevitably involved in a global strike mission.Of the many direct methods,Gauss pseudospectral method(GPM)has been demonstrated as an effective tool to solve the trajectory optimization problem with typical constraints.However,a series of diffculties arises for complex constraints,such as the uncertainty of passage time for waypoints and the inaccuracy of approximate trajectory near no-fly zones.The research herein proposes a multi-phase technique based on the GPM to generate an optimal reentry trajectory for HV satisfying waypoint and nofly zone constraints.Three kinds of specifc breaks are introduced to divide the full trajectory into multiple phases.The continuity conditions are presented to ensure a smooth connection between each pair of phases.Numerical examples for reentry trajectory optimization in free-space flight and with complex constraints are used to demonstrate the proposed technique.Simulation results show the feasible application of multi-phase technique in reentry trajectory optimization with waypoint and no-fly zone constraints. | Jiang Zhao Rui Zhou | 2013 | Chinese Journal of Aeronautics2013,26,6: | 56 |

| 6 | Three-dimensional cooperative guidance laws against stationary and maneuvering targets显示文摘This paper presents the cooperative strategies for salvo attack of multiple missiles based on the classical proportional navigation(PN) algorithm.The three-dimensional(3-D) guidance laws are developed in a quite simple formulation that consists of a PN component for target capture and a coordination component for simultaneous arrival.The centralized algorithms come into effect when the global information of time-to-go estimation is obtained, whereas the decentralized algorithms have better performance when each missile can only collect information from neighbors.Numerical simulations demonstrate that the proposed coordination algorithms are feasible to perform the cooperative engagement of multiple missiles against both stationary and maneuvering targets.The effectiveness of the 3-D guidance laws is also discussed. | Zhao Jiang Zhou Rui Dong Zhuoning | 2015 | Chinese Journal of Aeronautics2015,28,4: | 28 |
| 7 | Manganese is critical for antitumor immune responses via cGAS-STING and improves the efficacy of clinical immunotherapy显示文摘CD8^+T cell-mediated cancer clearance is often suppressed by the interaction between inhibitory molecules like PD-1 and PD-L1,an interaction acts like brakes to prevent T cell overreaction under normal conditions but is exploited by tumor cells to escape the immune surveillance.Immune checkpoint inhibitors have revolutionized cancer therapeutics by removing such brakes.Unfortunately,only a minority of cancer patients respond to immunotherapies presumably due to inadequate immunity.Antitumor immunity depends on the activation of the cGAS-STING pathway,as STING-deficient mice fail to stimulate tumor-infiltrating dendritic cells(DCs)to activate CD8^+T cells.STING agonists also enhance natural killer(NK)cells to mediate the clearance of CD8^+T cell-resistant tumors.Therefore STING agonists have been intensively sought after.We previously discovered that manganese(Mn)is indispensable for the host defense against cytosolic dsDNA by activating cGAS-STING.Here we report that Mn is also essential in innate immune sensing of tumors and enhances adaptive immune responses against tumors.Mn-insufficient mice had significantly enhanced tumor growth and metastasis,with greatly reduced tumor-infiltrating CD8^+T cells.Mechanically,Mn^2+promoted DC and macrophage maturation and tumor-specific antigen presentation,augmented CD8^+T cell differentiation,activation and NK cell activation,and increased memory CD8^+T cells.Combining Mn^2+with immune checkpoint inhibition synergistically boosted antitumor efficacies and reduced the anti-PD-1 antibody dosage required in mice.Importantly,a completed phase 1 clinical trial with the combined regimen of Mn^2+and anti-PD-1 antibody showed promising efficacy,exhibiting type I IFN induction,manageable safety and revived responses to immunotherapy in most patients with advanced metastatic solid tumors.We propose that this combination strategy warrants further clinical translation. | Mengze Lv Meixia Chen Rui Zhang Wen Zhang Chenguang Wang Yan Zhang Xiaoming Wei Yukun Guan Jiejie Liu Kaichao Feng Miao Jing Xurui Wang Yun-Cai Liu Qian Mei Weidong Han Zhengfan Jiang | 2020 | Cell Research2020,30,11: | 27 |
| 8 | Progress in reentry trajectory planning for hypersonic vehicle显示文摘The reentry trajectory planning for hypersonic vehicles is critical and challenging in the presence of numerous nonlinear equations of motion and path constraints, as well as guaranteed satisfaction of accuracy in meeting all the specified boundary conditions. In the last ten years, many researchers have investigated various strategies to generate a feasible or optimal constrained reentry trajectory for hypersonic vehicles. This paper briefly reviews the new research efforts to promote the capability of reentry trajectory planning. The progress of the onboard reentry trajectory planning, reentry trajectory optimization, and landing footprint is summarized. The main challenges of reentry trajectory planning for hypersonic vehicles are analyzed, focusing on the rapid reentry trajectory optimization, complex geographic constraints, and cooperative strategies. | Jiang Zhao Rui Zhou Xuelian Jin | 2014 | Journal of Systems Engineering and Electronics2014,25,4: | 25 |
| 9 | Particle swarm optimization applied to hypersonic reentry trajectories显示文摘This paper presents the novel use of the particle swarm optimization(PSO)to generate the end-to-end trajectory for hypersonic reentry vehicles in a quite simple formulation.The velocitydependent bank angle profile is developed to reduce the search space of unknown parameters based on the constrained PSO algorithm.The path constraints are enforced by setting the fitness function to be infinite on condition that the particles violate the maximum allowable values.The PSO algorithm also provides a much easier means to satisfy the terminal conditions by adding penalty terms to the fitness function.Furthermore,the approximate reentry landing footprint is fast constructed by incorporating an interpolation model into the standardized bank angle profiles.Numerical simulations demonstrate that the PSO method is a feasible and flexible tool to generate the end-to-end trajectory and landing footprint for hypersonic reentry vehicles. | Zhao Jiang Zhou Rui | 2015 | Chinese Journal of Aeronautics2015,28,3: | 24 |

| 12 | Effects of arbuscular mycorrhizal fungi inoculation on arsenic accumulation by tobacco (Nicotiana tabacum L.)显示文摘A pot experiment was conducted to study the effects of arbuscular mycorrhizal(AM) fungi(from contaminated or uncontaminated soils) on arsenic(As) uptake of tobacco(Nicotiana tabacum L.) in As-contaminated soil.Mycorrhizal colonization rate,dry weight,As and P uptake by plants,concentrations of water-extractable As and As fractions were determined.A low mycorrhizal colonization rate(<25%) was detected.Our research indicated that AM fungi isolated from polluted soils were no more effective than those from unpolluted soils when grown in symbiosis with tobacco.No significant differences were observed in roots and stalks dry weights among all treatments.Leaves and total plant dry weights were much higher in Glomus versiforme treatment than that in control treatment.As contents in roots and stalks from mycorrhizal treatments were much lower than that from control treatment.Total plant As content exhibited the same trend.P concentrations in tobacco were not affected by colonization,nor were stalks,leaves and total plant P contents.Roots P contents were remarkably lower in HN treatments than in other treatments.Meanwhile,decreased soil pH and lower water-extractable As concentrations and higher levels of As fraction bound to well-crystallized hydrous oxides of Fe and Al were found in mycorrhizal treatments than in controls.The protective effect of mycorrhiza against plant As uptake may be associated with changes in As solubility mediated by changing soil pH.These results indicated that under As stress,proper mechanisms employed by AM fungi can protect tobacco against As uptake.Results confirmed that AM fungi can play an important role in food quality and safety. | HUA Jianfeng LIN Xiangui YIN Rui JIANG Qian SHAO Yufang | 2009 | Journal of Environmental Sciences2009,21,9: | 19 |
| 13 | Exogenous NADPH ameliorates myocardial ischemia–reperfusion injury in rats through activating AMPK/mTOR pathway显示文摘Our previous study shows that nicotinamide adenine dinucleotide phosphate(NADPH)plays an important role in protecting against cerebral ischemia injury.In this study we investigated whether NADPH exerted cardioprotection against myocardial ischemia/reperfusion(I/R)injury.To induce myocardial I/R injury,rats were subjected to ligation of the left anterior descending branch of coronary artery for 30 min followed by reperfusion for 2 h.At the onset of reperfusion,NADPH(4,8,16 mg·kg?1·d?1,iv)was administered to the rats.We found that NADPH concentrations in plasma and heart were signi?cantly increased at 4 h after intravenous administration.Exogenous NADPH(8?16 mg/kg)signi?cantly decreased myocardial infarct size and reduced serum levels of lactate dehydrogenase(LDH)and cardiac troponin I(cTn-I).Exogenous NADPH signi?cantly decreased the apoptotic rate of cardiomyocytes,and reduced the cleavage of PARP and caspase-3.In addition,exogenous NADPH reduced mitochondrial vacuolation and increased mitochondrial membrane protein COXIV and TOM20,decreased BNIP3L and increased Bcl-2 to protect mitochondrial function.We conducted in vitro experiments in neonatal rat cardiomyocytes(NRCM)subjected to oxygen–glucose deprivation/restoration(OGD/R).Pretreatment with NADPH(60,500 nM)signi?cantly rescued the cell viability and inhibited OGD/R-induced apoptosis.Pretreatment with NADPH signi?cantly increased the phosphorylation of AMPK and downregulated the phosphorylation of mTOR in OGD/R-treated NRCM.Compound C,an AMPK inhibitor,abolished NADPH-induced AMPK phosphorylation and cardioprotection in OGD/R-treated NRCM.In conclusion,exogenous NADPH exerts cardioprotection against myocardial I/R injury through the activation of AMPK/mTOR pathway and inhibiting mitochondrial damage and cardiomyocyte apoptosis.NADPH may be a potential candidate for the prevention and treatment of myocardial ischemic diseases. | Jiang Zhu Yi-fei Wang Xiao-ming Chai Ke Qian Ling-wei Zhang Peng Peng Pei-min Chen Jian-fang Cao Zheng-hong Qin Rui Sheng Hong Xie | 2020 | Acta Pharmacologica Sinica2020,41,4: | 19 |
| 14 | Improvement of orbit determination for geostationary satellites with VLBI tracking显示文摘China’s COMPASS satellite navigation system consists of five or more geostationary (GEO) satellites.The roles of GEO satellites are to improve the regional user’s positioning accuracy and provide the continuous Radio Determination Satellite Service.The motion of GEO satellites relative to a ground tracking station is almost fixed,and regular orbit maneuvers are necessary to maintain the satellites’ allocated positions above the equator.These features present difficulties in precise orbit determination (POD).C-band ranging via onboard transponders and the L-band pseudo-ranging technique have been used in the COMPASS system.This paper introduces VLBI tracking,which has been successfully employed in the Chinese lunar exploration programs Chang’E-1 and Chang’E-2,to the POD of GEO satellites.In contrast to ranging,which measures distances between a GEO satellite and an observer,VLBI is an angular measurement technique that constrains the satellite’s position errors perpendicular to the satellite-to-observer direction.As a demonstration,the Chinese VLBI Network organized a tracking and orbit-determination experiment for a GEO navigation satellite lasting 24 h.This paper uses the VLBI delay and delay-rate data,in combination with C-band ranging data,to determine the GEO satellite’s orbit.The accuracies of the VLBI delay and delay rate data are about 3.6 ns and 0.4 ps/s,respectively.Data analysis shows that the VLBI data are able to calibrate systematic errors of the C-band ranging data,and the combination of the two observations improves orbit prediction accuracy with short-arc data,which is important for orbital recovery after maneuvers of GEO satellites.With the implementation of VLBI2010,it is possible for VLBI to be applied in the COMPASS satellite navigation system. | HUANG Yong HU XiaoGong ZHANG XiuZhong JIANG DongRong GUO Rui WANG Hong SHI ShanBin | 2011 | Chinese Science Bulletin2011,56,26: | 18 |
| 15 | Single-cell transcriptomic analysis defines the interplay between tumor cells,viral infection,and the microenvironment in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an Epstein-Barr virus(EBV)-associated malignancy with a complex tumor ecosystem.How the interplay between tumor cells,EBV,and the microenvironment contributes to NPC progression and immune evasion remains unclear.Here we performed single-cell RNA sequencing on^104,000 cells from 19 EBV^+NPCs and 7 nonmalignant nasopharyngeal biopsies,simultaneously profiling the transcriptomes of malignant cells,EBV,stromal and immune cells.Overall,we identified global upregulation of interferon responses in the multicellular ecosystem of NPC.Notably,an epithelial–immune dual feature of malignant cells was discovered and associated with poor prognosis.Functional experiments revealed that tumor cells with this dual feature exhibited a higher capacity for tumorigenesis.Further characterization of the cellular components of the tumor microenvironment(TME)and their interactions with tumor cells revealed that the dual feature of tumor cells was positively correlated with the expression of co-inhibitory receptors on CD8^+tumor-infiltrating T cells.In addition,tumor cells with the dual feature were found to repress IFN-γproduction by T cells,demonstrating their capacity for immune suppression.Our results provide new insights into the multicellular ecosystem of NPC and offer important clinical implications. | Shanzhao Jin Ruoyan Li Ming-Yuan Chen Chao Yu Lin-Quan Tang Yan-Min Liu Jiang-Ping Li Yi-Na Liu Yi-Ling Luo Yifan Zhao Yu Zhang Tian-Liang Xia Shang-Xin Liu Qi Liu Guan-Nan Wang Rui You Jing-Yun Peng Jiang Li Feng Han Jianwei Wang Qiu-Yan Chen Li Zhang Hai-Qiang Mai Benjamin E.Gewurz Bo Zhao Lawrence S.Young Qian Zhong Fan Bai Mu-Sheng Zeng | 2020 | Cell Research2020,30,11: | 16 |

| 18 | Comparison of dust emissions, transport, and deposition between the Taklimakan Desert and Gobi Desert from 2007 to 2011显示文摘The Taklimakan Desert(TD) and Gobi Desert(GD) are two of the most important dust sources in East Asia, and have important impact on energy budgets, ecosystems and water cycles at regional and even global scales. To investigate the contribution of the TD and the GD to dust concentrations in East Asia as a whole, dust emissions, transport, and deposition over the TD and the GD in different seasons from 2007 to 2011 were systematically compared, based on the Weather Research and Forecasting model coupled with Chemistry(WRF-Chem). Dust emissions, uplift, and long-range transport related to these two dust source regions were markedly different due to differences in topography, elevation, thermal conditions, and atmospheric circulation. Specifically,the topography of the GD is relatively flat, and at a high elevation, and the area is under the influence of two jet streams at high altitudes, resulting in high wind speeds in the upper atmosphere. Deep convective mixing enables the descending branch of jet streams to continuously transport momentum downward to the mid-troposphere, leading to enhanced wind speeds in the lower troposphere over the GD which favors the vertical uplift of the GD dust particles. Therefore, the GD dust was very likely to be transported under the effect of strong westerly jets, and thus played the most important role in contributing to dust concentrations in East Asia. Approximately 35% and 31% of dust emitted from the GD transported to remote areas in East Asia in spring and summer, respectively. The TD has the highest dust emission capabilities in East Asia, with emissions of about 70.54 Tg yr.1 in spring, accounting for 42% of the total dust emissions in East Asia. However, the TD is located in the Tarim Basin and surrounded by mountains on three sides. Furthermore, the dominant surface wind direction is eastward and the average wind speed at high altitudes is relatively small over the TD. As a result, the TD dust particles are not easily transported outside the Tarim Basin, such that most of the dust particles are re-deposited after uplift, at a total deposition rate of about 40 g m.2. It is only when the TD dust particles are uplifted above 4 km, and entrained in westerlies that they begin to undergo a long-range transport. Therefore,the contribution of the TD dust to East Asian dust concentrations was relatively small. Only 25% and 23% of the TD dust was transported to remote areas over East Asia in spring and summer, respectively. | CHEN SiYu HUANG JianPing LI JingXin JIA Rui JIANG NanXuan KANG LiTai MA XiaoJun XIE TingTing | 2017 | Science China Earth Sciences2017,60,7: | 14 |
| 19 | Electrochemical performance of a nickel-rich LiNi0.6Co0.2Mn0.2O2 cathode material for lithium-ion batteries under different cut-off voltages显示文摘A spherical-like Ni_(0.6)Co_(0.2)Mn_(0.2)(OH)_2 precursor was tuned homogeneously to synthesize LiNi_(0.6)Co_(0.2)Mn_(0.2)O_2 as a cathode material for lithium-ion batteries.The effects of calcination temperature on the crystal structure,morphology,and the electrochemical performance of the as-prepared LiNi_(0.6)Co_(0.2)Mn_(0.2)O_2 were investigated in detail.The as-prepared material was characterized by X-ray diffraction,scanning electron microscopy,laser particle size analysis,charge–discharge tests,and cyclic voltammetry measurements.The results show that the spherical-like LiNi_(0.6)Co_(0.2)Mn_(0.2)O_2 material obtained by calcination at 900°C displayed the most significant layered structure among samples calcined at various temperatures,with a particle size of approximately 10 μm.It delivered an initial discharge capacity of 189.2 m Ah×g^(-1) at 0.2C with a capacity retention of 94.0% after 100 cycles between 2.7 and 4.3 V.The as-prepared cathode material also exhibited good rate performance,with a discharge capacity of 119.6 m Ah×g^(-1) at 5C.Furthermore,within the cut-off voltage ranges from 2.7 to 4.3,4.4,and 4.5 V,the initial discharge capacities of the calcined samples were 170.7,180.9,and 192.8 m Ah×g^(-1),respectively,at a rate of 1C.The corresponding retentions were 86.8%,80.3%,and 74.4% after 200 cycles,respectively. | Kai-lin Cheng Dao-bin Mu Bo-rong Wu Lei Wang Ying Jiang Rui Wang | 2017 | International Journal of Minerals,Metallurgy and Materials2017,24,3: | 14 |
| 20 | Novel and potent inhibitors targeting DHODH are broad-spectrum antivirals against RNA viruses including newly-emerged coronavirus SARS-CoV-2显示文摘Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide,such as the on-going outbreak of the novel coronavirus SARS-CoV-2.Herein,we identified two potent inhibitors of human DHODH,S312 and S416,with favorable drug-likeness and pharmacokinetic profiles,which all showed broad-spectrum antiviral effects against various RNA viruses,including influenza A virus,Zika virus,Ebola virus,and particularly against SARS-CoV-2.Notably,S416 is reported to be the most potent inhibitor so far with an EC5o of 17 nmol/L and an SI value of 10,505.88 in infec-ted cells.Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells.This work demonstrates that both S312/S416 and old drugs(Leflunomide/Teriflunomide)with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide,no matter such viruses are mutated or not. | Rui Xiong Leike Zhang Shiliang Li Yuan Sun Minyi Ding Yong Wang Yongliang Zhao Yan Wu Weijuan Shang Xiaming Jiang Jiwei Shan Zihao Shen Yi Tong Liuxin Xu Yu Chen Yingle Liu Gang Zou Dimitri Lavillete Zhenjiang Zhao Rui Wang Lili Zhu Gengfu Xiao Ke Lan Honglin Li Ke Xu | 2020 | Protein & Cell2020,11,10: | 14 |
