| 1 | The impacts of conservation agriculture on crop yield in China depend on specific practices, crops and cropping regions显示文摘For smooth and wide application of conservation agriculture(CA), remaining uncertainties about its impacts on crop yield need to be reduced. Based on previous field experiments in China, a meta-analysis was performed to quantify the actual impacts of CA practices(NT: no/reduced-tillage only, CTSR: conventional tillage with straw retention, NTSR: NT with straw retention) on crop yields as compared to conventional tillage without straw retention(CT).Although CA practices increased crop yield by 4.6% on average, there were large variations in their impacts. For each CA practice, CTSR and NTSR significantly increased crop yield by 4.9%and 6.3%, respectively, compared to CT. However, no significant effect was found for NT. Among ecological areas, significant positive effects of CA practices were found in areas with an annual precipitation below 600 mm. Similar effects were found in areas with annual mean air temperature above 5 °C. For cropping regions, CA increased crop yield by 6.4% and 5.5%compared to CT in Northwest and South China, respectively, whereas no significant effects were found in the North China and Northeast China regions. Among crops, the positive effects of CA practices were significantly higher in maize(7.5%) and rice(4.1%) than in wheat(2.9%). NT likely decreased wheat yield. Our results indicate that there are great differences in the impacts of CA practices on crop yield, owing to regional variation in climate and crop types. CA will most likely increase maize yield but reduce wheat yield. It is strongly recommended to apply CA with crop straw retention in maize cropping areas and seasons with a warm and dry climate pattern. | Chengyan Zheng Yu Jiang Changqing Chen Yanni Sun Jinfei Feng Aixing Deng Zhenwei Song Weijian Zhang | 2014 | The Crop Journal2014，2，5： | 15 |
| 2 | Source attributions of heavy metals in rice plant along highway in Eastern China显示文摘Air and soil pollution from traffic has been considered as a critical issue to crop production and food safety, however, few efforts have been paid on distinguish the source origin of traffic-related contaminants in rice plant along highway. Therefore, we investigated metals (Pb, Cd, Cr, Zn and Cu) concentrations and stable Pb isotope ratios in rice plants exposed and unexposed to highway traffic pollution in Eastern China in 2008. Significant differences in metals concentrations between the exposed and unexposed plants existed in leaf for Pb, Cd and Zn, in stem only for Zn, and in grain for Pb and Cd. About 46% of Pb and 41% of Cd in the grain were attributed to the foliar uptake from atmosphere, and there were no obvious contribution of atmosphere to the accumulations of Cr, Zn and Cu in grain. Except for Zn, all of the heavy metals in stem were attributed to the root uptake from soil, although significant accumulations of Pb and Cd from atmosphere existed in leaf. This indicated that different processes existed in the subsequent translocation of foliar-absorbed heavy metals between rice organs. The distinct separation of stable Pb isotope ratios among rice grain, leaf, stem, soil and vehicle exhaust further provided evidences on the different pathways of heavy metal accumulation in rice plant. These results suggested that further more attentions should be paid to the atmospheric deposition of heavy metals from traffic emission when plan crop layout for food safety along highway. | Jinfei Feng Yinxi Wang Jian Zhao Liqun Zhu Xinmin Bian Weijian Zhang | 2011 | Journal of Environmental Sciences2011，23，7： | 12 |
| 3 | Cropping system innovation for coping with climatic warming in China显示文摘China is becoming the largest grain producing and carbon-emitting country in the world,with a steady increase in population and economic development.A review of Chinese experiences in ensuring food self-sufficiency and reducing carbon emission in the agricultural sector can provide a valuable reference for similar countries and regions.According to a comprehensive review of previous publications and recent field observations,China has experienced on average a larger and faster climatic warming trend than the global trend,and there are large uncertainties in precipitation change,which shows a non-significantly increasing trend.Existing evidence shows that the effects of climatic warming on major staple crop production in China could be markedly negative or positive,depending on the specific cropping region,season,and crop.However,historical data analysis and field warming experiments have shown that moderate warming,of less than2.0 °C,could benefit crop production in China overall.During the most recent warming decades,China has made successful adaptations in cropping systems,such as new cultivar breeding,cropping region adjustment,and cropping practice optimization,to exploit the positive rather than to avoid the negative effects of climatic warming on crop growth.All of these successful adaptations have greatly increased crop yield,leading to higher resource use efficiency as well as greatly increased soil organic carbon content with reduced greenhouse gas emissions.Under the warming climate,China has not only achieved great successes in crop production but also realized a large advance in greenhouse gas emission mitigation.Chinese experiences in cropping system innovation for coping with climatic warming demonstrate that food security and climatic warming mitigation can be synergized through policy,knowledge,and technological innovation.With the increasingly critical status of food security and climatic warming,further efforts should be invested in new agricultural policy,knowledge and technology creation,and popularization of climate-smart agriculture,and more financial investments should be made in field infrastructure development to increase cropping system resilience in China. | Aixing Deng Changqing Chen Jinfei Feng Jin chen Weijian Zhang | 2017 | The Crop Journal2017，5，2： | 7 |
| 4 | Effects of Rice-Fish Co-culture on Oxygen Consumption in Intensive Aquaculture Pond显示文摘Rice-fish co-culture has gained increasing attention to remediate the negative environmental impacts induced by intensive aquaculture. However, the effect of rice-fish co-culture on oxygen depletion has rarely been investigated. We constructed a rice-fish co-culture system in yellow catfish(Pelteobagrus fulvidraco) and freshwater shrimp(Macrobrachium nipponense) ponds using a new high-stalk rice variety, and conducted a field experiment to investigate the effect of rice-fish co-culture on water parameters and oxygen consumption. The results showed that rice-fish co-culture reduced the nutrients(total nitrogen, ammonia-N, total phosphorous and potassium) and the dissolved oxygen content in fish and shrimp ponds. However, they showed similar seasonal change of dissolved oxygen in the water of fish and shrimp ponds. Rice-fish co-culture reduced the total amount of oxygen consumption and optimized the oxygen consumption structure in pond. The respiration rates in water and sediment were significantly reduced by 66.1% and 31.7% in the catfish pond, and 64.4% and 38.7% in the shrimp pond, respectively, by additional rice cultivation. Rice-fish co-culture decreased the proportions of respiration in sediment and water, and increased the proportion of fish respiration. These results suggest that rice-fish co-culture is an efficient way to reduce hypoxia in intensive culture pond. | LI Fengbo SUN Zhiping QI Hangying ZHOU Xiyue XU Chunchun WU Dianxin FANG Fuping FENG Jinfei ZHANG Ning | 2019 | Rice science2019，26，1： | 4 |
| 5 | Impact of Rice-Catfish/Shrimp Co-culture on Nutrients Fluxes Across Sediment-Water Interface in Intensive Aquaculture Ponds显示文摘Exchange of nitrogen and phosphorus across sediment-water interface plays an important role in the management of nutrient recycling in the aquaculture pond. In this study, a plot experiment was conducted to study the effect of rice-catfish/shrimp co-culture on the micro-profile of oxygen (O2), pH and nutrient exchange across sediment-water interface in the intensive culture ponds. The results showed that rice-catfish co-culture increased the concentration and penetrating depth of O2, but decreased the pH value across the sediment-water interface, compared with catfish monoculture. Additional rice cultivation significantly reduced the flux rates of ammonium (NH4+) and nitrate (NO3-) across sediment-water interface in the catfish and shrimp ponds. The flux rates of NO2 - and soluble phosphorus (PO43-) showed no significant difference between rice-catfish/shrimp co-culture ponds and catfish/shrimp monoculture ponds. Rice only affected the dissolved inorganic nitrogen and phosphorus fractions in the sediment. The concentrations of NH4 + were significantly lower in the sediment of co-culture ponds than in the monoculture ponds. Additional rice cultivation also significantly reduced the content and percentage of dissolved inorganic phosphorus in the sediment of catfish ponds. | LIU Yaobin QIN Lin LI Fengbo ZHOU Xiyue XU Chunchun JI Long CHEN Zhongdu FENG Jinfei FANG Fuping | 2019 | Rice science2019，26，6： | 4 |
| 6 | A Task-oriented Modular and Agent-based Collaborative Design Mechanism for Distributed Product Development显示文摘The rapid expansion of enterprises makes product collaborative design(PCD)a critical issue under the distributed heterogeneous environment,but as the collaborative task of large-scale network becomes more complicated,neither unified task decomposition and allocation methodology nor Agent-based network management platform can satisfy the increasing demands.In this paper,to meet requirements of PCD for distributed product development,a collaborative design mechanism based on the thought of modularity and the Agent technology is presented.First,the top-down 4-tier process model based on task-oriented modular and Agent is constructed for PCD after analyzing the mapping relationships between requirements and functions in the collaborative design.Second,on basis of sub-task decomposition for PCD based on a mixed method,the mathematic model of task-oriented modular based on multi-objective optimization is established to maximize the module cohesion degree and minimize the module coupling degree,while considering the module executable degree as a restriction.The mathematic model is optimized and simulated by the modified PSO,and the decomposed modules are obtained.Finally,the Agent structure model for collaborative design is put forward,and the optimism matching Agents are selected by using similarity algorithm to implement different task-modules by the integrated reasoning and decision-making mechanism with the behavioral model of collaborative design Agents.With the results of experimental studies for automobile collaborative design,the feasibility and efficiency of this methodology of task-oriented modular and Agent-based collaborative design in the distributed heterogeneous environment are verified.On this basis,an integrative automobile collaborative R&D platform is developed.This research provides an effective platform for automobile manufacturing enterprises to achieve PCD,and helps to promote product numeralization collaborative R&D and management development. | LIU Jinfei CHEN Ming WANG Lei WU Qidi | 2014 | Chinese Journal of Mechanical Engineering2014，27，3： | 4 |
| 7 | Integrative Analysis Reveals Enhanced Regulatory Effects of Human Long Intergenic Non-Coding RNAs in Lung Adenocarcinoma显示文摘Although there is an accumulating appreciation of the key roles that long intergenic non-coding RNAs(linc RNAs) play in diverse cellular processes, our knowledge of how linc RNAs function in cancer remains sparse. Here, we present a comprehensive landscape of RNA-seq transcriptome profiles of lung adenocarcinomas and their paired normal counterparts to unravel gene regulation rules of linc RNAs.Consistent with previous findings of co-expression between neighboring protein-coding genes, linc RNAs were typically co-expressed with their neighboring genes, which was found in both cancerous and normal tissues. By building a mathematical model based on correlated gene expression, we distinguished an additional subset of linc RNAs termed 'regulatory linc RNAs', representing their dominant roles in gene regulation. The number of regulatory linc RNAs was significantly higher in cancerous compared to normal tissues, and most of them positively regulated protein-coding genes in trans. Functional validation, using knockdown, determined that regulatory linc RNA,GAS5, affected its predicted protein-coding targets. Moreover, we discovered hundreds of differentially expressed regulatory linc RNAs with inclusion of some cancer-associated linc RNAs. Our integrated analysis reveals enhanced regulatory effects of linc RNAs and provides a resource for the study of regulatory linc RNAs that play critical roles in lung adenocarcinoma. | You Zhou Kai Wu Jianping Jiang Jinfei Huang Peiwei Zhang Yufei Zhu Guohong Hu Jingyu Lang Yufang Shi Landian Hu Tao Huang Xiangyin Kong | 2015 | Journal of Genetics and Genomics2015，42，8： | 3 |

| 9 | Experimental research on the heating performance of a single cylinder refrigerant injection rotary compressor heat pump with flash tank显示文摘A single cylinder rotary compressor was applied in the refrigerant injection air-source heat pump to improve the heating performance in cold regions. In this study, the performance of an R410 A single cylinder rotary compressor vapor injection(SCRCVI) system was measured and analyzed by varying the compressor frequency f and injection pressure Pi njat the ambient temperature To d=–10°C.The experimental results indicated that an optimum injection pressure to gain the maximum COP_h (coefficient of performance) existed in the SCRCVI cycle. However, the maximum COP_h of the SCRCVI system decreased as the increase of the frequency, and the maximum COPhwas even lower than that of the CSVC system at high compressor frequency. Therefore, in view of the energy saving and emission reduction, the SCRCVI system should be switched to single stage compression system when the heating capacity demand could be satisfied at high compressor frequency f. Compared to the conventional single-stage vapor compression(CSVC) system, refrigerant injection could enhance the heating capacities and COP_h by 28.2% and 7.91%, respectively. The average total mass flow rate of the SCRCVI system was 24.68% higher than that of the CSVC system. As the SCRCVI system worked at the optimum injection pressure, the variation trends of the different system parameters were investigated in detail. These trends were reliably used to optimize the refrigerant injection system design and the control strategy. The parameter of(P_(inj)–P_s) could be adopted as the signals to control the opening of the upper stage electronic expansion valve EEV1. | SUN JinFei ZHU DongSheng YIN YingDe LI XiuZhen | 2018 | Science China(Technological Sciences)2018，61，12： | 3 |

| 11 | Nitrogen addition and mowing alter drought resistance and recovery of grassland communities显示文摘Nitrogen enrichment and land use are known to influence various ecosystems,but how these anthropogenic changes influence community and ecosystem responses to disturbance remains poorly understood.Here we investigated the effects of increased nitrogen input and mowing on the resistance and recovery of temperate semiarid grassland experiencing a three-year drought.Nitrogen addition increased grassland biomass recovery but decreased structural recovery after drought,whereas annual mowing increased grassland biomass recovery and structural recovery but reduced structural resistance to drought.The treatment effects on community biomass/structural resistance and recovery were largely modulated by the stability of the dominant species and asynchronous dynamics among species,and the community biomass resistance and recovery were also greatly driven by the stability of grasses.Community biomass resistance/recovery in response to drought was positively associated with its corresponding structural stability.Our study provides important experimental evidence that both nitrogen addition and mowing could substantially change grassland stability in both functional and structural aspects.Our findings emphasize the need to study changes across levels of ecological organization for a more complete understanding of ecosystem responses to disturbances under widespread environmental changes. | Zhuwen Xu Heyong Liu Yani Meng Jinfei Yin Haiyan Ren Mai-He Li Shan Yang Shiming Tang Yong Jiang Lin Jiang | 2023 | Science China(Life Sciences)2023，66，7： | 2 |

| 19 | To Learn or Not to Learn:Deep Learning Assisted Wireless Modem Design显示文摘Deep learning is driving a radical paradigm shift in wireless communications,all the way from the application layer down to the physical layer.Despite this,there is an ongoing debate as to what additional values artificial intelligence(or machine learning)could bring to us,particularly on the physical layer design;and what penalties there may have?These questions motivate a fundamental rethinking of the wireless modem design in the artificial intelli gence era.Through several physicallayer case studies,we argue for a significant role that machine learning could play,for instance in parallel errorcontrol coding and decoding,channel equalization,interference cancellation,as well as multiuser and multiantenna detection.In addition,we discuss the fundamental bottlenecks of machine learning as well as their potential solutions in this paper. | XUE Songyan LI Ang WANG Jinfei YI Na MA Yi Rahim TAFAZOLLI Terence DODGSON | 2019 | ZTE Communications2019，17，4： | 1 |
