| 1 | Progress in inhomogeneity of critical current and index n value measurements on HTS tapes using contact-free method显示文摘The development of high temperature superconducting(HTS)tapes has recently made great progress,and Bi-based tapes(1 G) and YBCO coated conductor(2 G)are commercially fabricated with practical length.Application of HTS in electric power apparatuses made important achievement,various superconducting devices were demonstrated in grid,laying solid foundation for their commercialization.However,since their intrinsic microscopic defects such as weak-link,granularity,small second phase likely exist,critical current and index n value of the HTS tapes in practical length are impossible homogeneous,which have significant influences on safety,stability and efficiency of the HTS apparatuses.Therefore,critical current and index n value are two important parameters describing inhomogeneity of HTS tapes,thus two important indices for evaluating quality of practical long HTS tapes.This paper focuses on main progresses in inhomogeneity of critical current and index n value measurements on HTS tapes using contact-free methods.The statistical analytical methods evaluating the inhomogeneity of critical current and index n value are suggested.They can provide essential references for design and operation of HTS apparatuses. | WANG YinShun GUAN XiaoJin ZHANG HuiYuan LIU HongWei | 2010 | Science China(Technological Sciences)2010，53，8： | 8 |
| 2 | Diluted ferromagnetic semiconductor(LaCa)(ZnMn)SbO isostructural to “1111” type iron pnictide superconductors显示文摘We report discovery of ferromagnetism in(LaCa)(ZnMn)SbO isostructural to the well-studied iron-based superconductor LaFeAs(O1 xFx).Spin is induced by partial substitution of Mn2+for Zn2+,while charge is induced by substitution of Ca2+for La3+within the parent compound LaZnSbO.Ferromagnetism with Curie temperature(TC)is observed up to 40 K at the spin doping 0.15 by introducing Mn2+into the Zn2+sites for(La0.95Ca0.05)(Zn1 xMnx)SbO.The Hall coefficient measurement indicates p-type carrier for(La0.95Ca0.05)(Zn0.9Mn0.1)SbO with concentration of n^1020cm 3showing anomalous Hall effect below TC. | HAN Wei ZHAO Kan WANG XianCheng LIU QingQing NING FanLong DENG Zheng LIU Ying ZHU JinLong DING Cui MAN HuiYuan JIN ChangQing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 8 |

| 5 | Removal and transformation of organic matters in domestic wastewater during lab-scale chemically enhanced primary treatment and a trickling filter treatment显示文摘To find a simple and economical way for treating the domestic wastewater in small counties and towns, a process combining chemically enhanced primary treatment and a trickling filter (CEPT-TF, representing the physical and biological effects) was constructed and operated in laboratory conditions. The characteristic behaviors of dissolved organic matter in raw wastewater and effluents were examined during steady-state operation. Experimental results showed that the process of CEPT and TF in series was beneficial for the removal of hydrophobic and hydrophilic organics. Specially, the hydrophobic and aromatic materials could be preferentially removed in the CEPT unit, and the hydrophilic fraction in the TF. Structural changes of the organic fractions during the operation of the different units were also characterized via spectrum analysis. | Qingliang Zhao Huiyuan Zhong Kun Wang Liangliang Wei Jinli Liu Yu Liu | 2013 | Journal of Environmental Sciences2013，25，1： | 4 |
| 6 | Serum macrophage migration inhibitory factor as a potential biomarker to evaluate therapeutic response in patients with allergic asthma:an exploratory study显示文摘Background:Previous studies have shown that macrophage migration inhibitory factor(MIF)is involved in the pathogenesis of asthma.This study aimed to investigate whether serum MIF reflects a therapeutic response in allergic asthma.Methods:We enrolled 30 asthmatic patients with mild-to-moderate exacerbations and 20 healthy controls,analyzing the parameter levels of serum MIF,serum total immunoglobulin E(tIgE),peripheral blood eosinophil percentage(EOS%),and fractional exhaled nitric oxide(FeNO).Lung function indices were used to identify disease severity and therapeutic response.Results:Our study showed that all measured parameters in patients were at higher levels than those of controls.After one week of treatment,most parameter levels decreased significantly except for serum tIgE.Furthermore,we found that serum MIF positively correlated with EOS%as well as FeNO,but negatively correlated with lung function indices.Receiver operator characteristic(ROC)curve analysis indicated that among the parameters,serum MIF exhibited a higher capacity to evaluate therapeutic response.The area under the curve(AUC)of MIF was 0.931,with a sensitivity of 0.967 and a specificity of 0.800.Conclusions:Our results suggested that serum MIF may serve as a potential biomarker for evaluating therapeutic response in allergic asthma with mild-to-moderate exacerbations. | Huiyuan ZHU Shaochun YAN Jingshuo WU Zhong ZHANG Xiaolin LI Zheng LIU Xing MA Lina ZHOU Lin ZHANG Mingming FENG Yiwei GENG Aixin ZHANG Sabina JANCIAUSKIENE Aiguo XU | 2021 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021，22，6： | 3 |
| 7 | Fusobacterium nucleatum enhances the efficacy of PD-L1 blockade in colorectal cancer显示文摘Given that only a subset of patients with colorectal cancer(CRC)benefit from immune checkpoint therapy,efforts are ongoing to identify markers that predict immunotherapeutic response.Increasing evidence suggests that microbes influence the efficacy of cancer therapies.Fusobacterium nucleatum induces different immune responses in CRC with different microsatellite-instability(MSI)statuses.Here,we investigated the effect of F.nucleatum on anti-PD-L1 therapy in CRC.We found that high F.nucleatum levels correlate with improved therapeutic responses to PD-1 blockade in patients with CRC.Additionally,F.nucleatum enhanced the antitumor effects of PD-L1 blockade on CRC in mice and prolonged survival.Combining F.nucleatum supplementation with immunotherapy rescued the therapeutic effects of PD-L1 blockade.Furthermore,F.nucleatum induced PD-L1 expression by activating STING signaling and increased the accumulation of interferon-gamma(IFN-γ)^(+)CD8^(+)tumor-infiltrating lymphocytes(TILs)during treatment with PD-L1 blockade,thereby augmenting tumor sensitivity to PD-L1 blockade.Finally,patient-derived organoid models demonstrated that increased F.nucleatum levels correlated with an improved therapeutic response to PD-L1 blockade.These findings suggest that F.nucleatum may modulate immune checkpoint therapy for CRC. | Yaohui Gao Dexi Bi Ruting Xie Man Li Jing Guo Hu Liu Xianling Guo Juemin Fang Tingting Ding Huiyuan Zhu Yuan Cao Meichun Xing Jiayi Zheng Qing Xu Qian Xu Qing Wei Huanlong Qin | 2021 | Signal Transduction and Targeted Therapy2021，6，12： | 3 |
| 8 | Mode demultiplexing hybrids for mode-division multiplexing coherent receivers显示文摘We propose a mode demultiplexing hybrid(MDH) that integrates mode demultiplexing, local oscillator power splitting, and optical 90-deg mixing using multi-plane light conversion(MPLC). We demonstrate the realization of a three-mode MDH using four phase plates, one more than what is required for an MPLC-based mode demultiplexer, via numerical simulations. The performance of the three-mode MDH is comparable to that of commercial single-mode 90-deg hybrids. This multiple-functionality device enables simplification of the coherent optical front end of mode-division multiplexing receivers. | HE WEN HUIYUAN LIU YUANHANG ZHANG PENG ZHANG GUIFANG LI | 2019 | Photonics Research2019，7，8： | 3 |
| 9 | VOCs released from municipal solid waste at the initial decomposition stage: Emission characteristics and an odor impact assessment显示文摘The nuisance from odor caused by municipal solid waste(MSW) is resulting in a growing number of public complaints and concerns. Odor pollution occurs in the initial decomposition stage of MSW, including waste collection, transportation and early pre-treatment. Furthermore, decomposition takes place in waste facilities that are often close to living areas, which can result in odor impacts on local inhabitants. However, this aspect of odor impact from MSW has not been well studied. In the current study, lab-scale waste cells were designed to simulate MSW storage conditions in the early stage. The characteristics of VOCs emissions with different waste compositions were analyzed. The odor concentration( CO, non-dimensional) method and odor intensity were used for the assessment of odor. Ethanol was the substance with highest emission rate. The release rate of VOCs increased with the growth easily biodegradable waste(EBW). VOCs emissions was reduced by 25% when the proportion of EBW decreased from 60% to 45%. Methyl sulfide, ethanol, dimethyl disulfide and ethyl acetate were identified as typical odorants. The EBW proportion in waste is the main factor significantly influencing odor pollution. The CO was 244.51 for the 60% EBW condition, which was only 61.46 for 15% EBW condition. These study results provide important information for the implementation of a garbage sorting policy and the monitoring of odor pollution from waste management. | Yanjun Liu Huiyuan Yang Wenjing Lu | 2020 | Journal of Environmental Sciences2020，32，12： | 3 |
| 10 | Application of non-equilibrium dendrite growth model considering thermo-kinetic correlation in twin-roll casting显示文摘Upon non-equilibrium solidifications, dendrite growth, generally as precursor of as-solidified structures,has severe effects on subsequent phase transformations. Considering synergy of thermodynamics and kinetics controlling interface migration and following conservation of heat flux in solid temperature field, a more flexible modeling for the dendrite growth is herein developed for multi-component alloys,where, two inherent problems, i.e. correlation between thermodynamics and kinetics(i.e. the thermokinetic correlation), and theoretical connection between dendrite growth model and practical processing,have been successfully solved. Accordingly, both the thermodynamic driving force G and the effective kinetic energy barrier Qeffhave been found to control quantitatively the dendrite growth(i.e. especially the growth velocity, V), as reflected by the thermo-kinetic trade-off. Compared with previous models, it is the thermo-kinetic correlation that guarantees quantitative connection between the practical processing parameters and the current theoretical framework, as well as more reasonable description for kinetic behaviors involved. Applied to the vertical twin-roll casting(VTC), the present model, realizes a good prediction for kissing points, which influences significantly alloy design and processing optimization.This work deduces quantitatively the thermo-kinetic correlation controlling the dendrite growth, and by proposing the parameter-triplets(i.e. G-Qeff-V), further opens a new beginning for connecting solidification theories with industrial applications, such as the VTC. | Yubing Zhang Jinglian Du Kang Wang Huiyuan Wang Shu Li Feng Liu | 2020 | Journal of Materials Science & Technology2020，44，9： | 2 |
| 11 | Crucial control measures to contain China's first Delta variant outbreak显示文摘The SARS-C oV-2 B.1.617.2(Delta) variant flared up in late May in Guangzhou,China.Transmission characteristics of Delta variant were analysed for 153 confirmed cases and two complete transmission chains with seven generations were fully presented.A rapid transmission occurred in five generations within10 days.The basic reproduction number(R_0) was 3.60(95% confidence interval:2.50-5.30).After redefining the concept of close contact,the proportion of confirmed cases discovered from close contacts increased from 43% to 100%.With the usage of a yellow health code,the potential exposed individuals were self-motivated to take a nucleic acid test and regained public access with a negative testing result.Facing the massive requirement of screening,novel facilities like makeshift inflatable laboratories were promptly set up as a vital supplement and 17 cases were found,with 1 pre-symptomatic.The dynamic adjustment of these three interventions resulted in the decline of Rt from 5.00 to 1.00 within 9 days.By breaking the transmission chain and eliminating the transmission source through extending the scope of the close-contact tracing,health-code usage and mass testing,the Guangzhou D elta epidemic was effectively contained. | Lei Luo Zifeng Yang Jingyi Liang Yu Ma Hui Wang Chitin Hon Mei Jiang Zhengshi Lin Wenda Guan Zhitong Mai Yongming Li Kailin Mai Zhiqi Zeng Chuanmeizi Tu Jian Song Bin Liu Yong Liu Jianfeng He Huiyuan Li Bosheng Li Hang Dong Yutian Miao Shujun Fan Lirui Fan Xingyi Liang Ke Li Chun Chen Huihong Deng Zhicong Yang Nanshan Zhong | 2022 | National Science Review2022，9，4： | 2 |
| 12 | Understanding the relationships between poverty alleviation and ecosystem conservation:empirical evidence from western China显示文摘Despite growing interest in the use of Payments for Ecosystem Services(PES)for both social and ecological benefits,few studies have investigated the feedback and interaction between poverty alleviation and ecosystem protection outcomes.In this study,the poverty reduction effects of PES policies and their subsequent influence on environmental protection outcomes are investigated.To address these questions,222 local rural households who were involved in PES programs from the Habahu National Nature Reserve in western China were interviewed.The results showed that the social and ecological outcomes of PES policies are neither two separate entities nor a trade-off.While rural households are the key participants in PES programs,the social and ecological outcomes of PES policies are closely related to each other.In addition,poverty reduction results could greatly influence ecosystem conservation effects.Livelihood assets,as well as the attitudes of rural households,play important roles in both of the outcomes.This research provides a new perspective that considers the social and ecological benefits of PES policies,and it also calls for an integrated consideration of social and ecological components in tihe design of PES policies to achieve enhanced results both for poverty alleviation and ecosystem conservation. | Xujun HU Huiyuan ZHANG Haiguang HAO Danyang FENG Haiyan LIU Qiang ZHANG | 2020 | Frontiers of Earth Science2020，14，1： | 2 |
| 13 | Exogenous SA or 6-BA maintains photosynthetic activity in maize leaves under high temperature stress显示文摘With global warming, high-temperature(HT) stress has become a major abiotic stress for crops, in particular summer maize in China. Photosynthesis is sensitive to HT. Salicylic acid(SA) and 6-benzyladenine(6-BA) can improve the adaptation of plants to various biotic and abiotic stresses. However, their contribution to maintaining photosynthetic activity and alleviating photoinhibition in maize leaves under HT stress is still unclear. The effects of exogenous SA or 6-BA on growth, photosynthesis capacity, photosystem Ⅱ(PSII) activity, subcellular ultrastructure, antioxidant system, and plant hormones in maize leaves under HT stress were investigated. Under HT conditions, application of SA or 6-BA up-regulated gibberellin and zeatin content in leaves, increasing leaf area index(LAI). It also expanded the stomata by reducing abscisic acid and jasmonic acid content in leaves, cooling them and increasing CO2supply to photosynthesis. A higher net photosynthetic rate, combined with increased activity of the antioxidant system, alleviated oxidative stress in maize plants sprayed with SA or 6-BA, allowing them to maintain their chloroplast ultrastructure and PSII activity, in particular electron transfer from QAto QB. The increased LAI and net photosynthetic rate per unit leaf area also resulted in the accumulation of more biomass. | Yuting Li Xuetao Han Hao Ren Bin Zhao Jiwang Zhang Baizhao Ren Huiyuan Gao Peng Liu | 2023 | The Crop Journal2023，11，2： | 2 |
| 14 | Few-mode fibre-optic microwave photonic links显示文摘The fibre-optic microwave photonic link has become one of the basic building blocks for microwave photonics.Increasing the optical power at the receiver is the best way to improve all link performance metrics including gain,noise figure and dynamic range.Even though lasers can produce and photodetectors can receive optical powers on the order of a Watt or more,the power-handling capability of optical fibres is orders-of-magnitude lower.In this paper,we propose and demonstrate the use of few-mode fibres to bridge this power-handling gap,exploiting their unique features of small acousto-optic effective area,large effective areas of optical modes,as well as orthogonality and walk-off among spatial modes.Using specially designed few-mode fibres,we demonstrate order-of-magnitude improvements in link performances for single-channel and multiplexed transmission.This work represents the first step in few-mode microwave photonics.The spatial degrees of freedom can also offer other functionalities such as large,tunable delays based on modal dispersion and wavelength-independent lossless signal combining,which are indispensable in microwave photonics. | He Wen Hongjun Zheng Qi Mo Amado Manuel Velázquez-Benítez Cen Xia Bin Huang Huiyuan Liu Huang Yu Pierre Sillard Jose Enrique Antonio Lopez Rodrigo Amezcua Correa Guifang Li | 2017 | Light(Science & Applications)2017，6，1： | 2 |

| 18 | Reconfigurable Intelligent Surface Assisted D2D Underlay Communications:A Two-Timescale Optimization Design显示文摘The performance of a device-to-device(D2D)underlay communication system is limited by the co-channel interference between cellular users(CUs)and D2D devices.To address this challenge,a reconfigurable intelligent surface(RIS)aided D2D underlay system is studied in this paper.A two-timescale optimization scheme is proposed to reduce the required channel training and feedback overhead,where transmit beamforming at the base station(BS)and power control at the D2D transmitters are adapted to instantaneous effective channel state information(CSI);and the RIS phase shifts are adapted to slow-varying channel mean.Based on the two-timescale optimization scheme,we aim to maximize the D2D ergodic weighted sum-rate(WSR)subject to a given outage probability constrained signal-to-interference-plus-noise ratio(SINR)target for each CU.The two-timescale problem is decoupled into two sub-problems,and the two sub-problems are solved iteratively.Numerical results verified that the two-timescale based optimization performs better than two baselines,and also demonstrated a favourable trade-off between system performance and CSI overhead. | Chang Cai Huiyuan Yang Xiaojun Yuan Ying-Jun Angela Zhang Yi Liu | 2020 | Journal of Communications and Information Networks2020，5，4： | 1 |
