| 1 | Shale Gas Play Screening and Evaluation Criteria显示文摘The uniqueness of shale gas plays is contrasted with conventional oil and gas exploration. Based on our ten year history in shale gas exploration, a practical 17 point list of criteria to use for screening shale gas projects and ranking that encompasses geoscience, geochemistry, reservoir engineering, drilling, completions and production operations is developed and explained. Other considerations that will impact shale gas development are identified and discussed. Some key methodologies to incorporate in the evaluation process are also proposed. The outcome of this proposed screening process, if rigorously applied, should quickly identify the projects that have the most likely chance for success for recommendation to management. Examples from active shale gas plays in the United States are used to support these criteria and references to relevant recent publications and presentations are provided. | Michael D.

| 2 | A MULTISCALE SOIL LOSS EVALUATION INDEX显示文摘Exploring the relationships between land use and soil erosion at different scales is a fron-tier research field and a hot spot topic in contempo-rary physical geography. Based on the scale-pattern-process theory in landscape ecology and with consideration of such influential factors as land use, topography, soil and rainfall, this paper ap-plies the scale transition method to establishing a soil loss evaluation index at different scales and puts forward a research path and methodology for mul-tiscale soil loss evaluation indices. The multiscale soil loss evaluation index is applied to the evaluation of relationships between land use and soil erosion and the research of soil erosion evaluation at multiple scales. It provides a new method for optimizing the design of regional land use patterns and integrated multiscale research. | FU Bojie ZHAO Wenwu CHEN Liding Lü Yihe WANG De | 2006 | Chinese Science Bulletin2006，51，4： | 22 |

| 5 | Economic power dispatch in smart grids: a framework for distributed optimization and consensus dynamics显示文摘By using the distributed consensus theory in multi-agent systems, the strategy of economic power dispatch is studied in a smart grid, where many generation units work cooperatively to achieve an optimal solution in a local area. The relationship between the distributed optimization solution and consensus in multi-agent systems is first revealed in this paper, which can serve as a general framework for future studies of this topic. First, without the constraints of capacity limitations, it is found that the total cost for all the generators in a smart grid can achieve the minimal value if the consensus can be reached for the incremental cost of all the generation units and the balance between the supply and demand of powers is kept. Then, by designing a distributed consensus control protocol in multi-agent systems with appropriate initial conditions,incremental cost consensus can be realized and the balance for the powers can also be satisfied. Furthermore,the difficult problem for distributed optimization of the total cost function with bounded capacity limitations is also discussed. A reformulated barrier function is proposed to simplify the analysis, under which the total cost can reach the minimal value if consensus can be achieved for the modified incremental cost with some appropriate initial values. Thus, the distributed optimization problems for the cost function of all generation units with and without bounded capacity limitations can both be solved by using the idea of consensus in multi-agent systems, whose theoretical analysis is still lacking nowadays. Finally, some simulation examples are given to verify the effectiveness of the results in this paper. | Wenwu YU Chaojie LI Xinghuo YU Guanghui WEN Jinhu LU | 2018 | Science China(Information Sciences)2018，61，1： | 13 |
| 6 | Phytophthora sojae Effector PsAvh240 Inhibits Host Aspartic Protease Secretion to Promote Infection显示文摘Plants secrete defense molecules into the extracellular space (the apoplast) to combat attacking microbes. However, the mechanisms by which successful pathogens subvert plant apoplastic immunity remain poorly understood. In this study, we show that PsAvh240, a membrane-localized effector of the soybean pathogen Phytophthora sojae, promotes P. sojae infection in soybean hairy roots. We found that PsAvh240 interacts with the soybean-resistant aspartic protease GmAP1 in planta and suppresses the secretion of GmAP1 into the apoplast. By solving its crystal structure we revealed that PsAvh240 contain six a helices and two WY motifs. The first two a helices of PsAvh240 are responsible for its plasma membrane-localization and are required for PsAvh240's interaction with GmAP1. The second WY motifs of two PsAvh240 molecules form a handshake arrangement resulting in a handshake-like dimer. This dimerization is required for the effector's repression of GmAP1 secretion. Taken together, these data reveal that PsAvh240 localizes at the plasma membrane to interfere with GmAP1 secretion, which represents an effective mechanism by which effector proteins suppress plant apoplastic immunity. | Baodian Guo Haonan Wang Bo Yang Wenjing Jiang Maofeng Jing Haiyang Li Yeqiang Xia Yuanpeng Xu Qinli Hu Fangfang Wang Feng Yu Yan Wang Wenwu Ye Suomeng Dong Weiman Xing Yuanchao Wang | 2019 | Molecular Plant2019，12，4： | 12 |
| 7 | Complex Cyber-Physical Networks: From Cybersecurity to Security Control显示文摘Complex cyber-physical network refers to a new generation of complex networks whose normal functioning significantly relies on tight interactions between its physical and cyber components. Many modern critical infrastructures can be appropriately modelled as complex cyber-physical networks. Typical examples of such infrastructures are electrical power grids, WWW, public transportation systems, state financial networks, and the Internet. These critical facilities play important roles in ensuring the stability of society as well as the development of economy. Advances in information and communication technology open opportunities for malicious attackers to launch coordinated attacks on cyber-physical critical facilities in networked infrastructures from any Internet-accessible place. Cybersecurity of complex cyber-physical networks has emerged as a hot topic within this context. In practice, it is also very crucial to understand the interplay between the evolution of underlying network structures and the collective dynamics on these complex networks and consequently to design efficient security control strategies to protect the evolution of these networks. In this paper, cybersecurity of complex cyber-physical networks is first outlined and then some security enhancing techniques,with particular emphasis on safety communications, attack detection and fault-tolerant control, are suggested. Furthermore, a new class of efficient secure control strategies are proposed for guaranteeing the achievement of desirable pinning synchronization behaviors in complex cyber-physical networks against malicious attacks on nodes. The authors hope that this paper motivates to design enhanced security strategies for complex cyber-physical network systems, to realize resilient and secure critical infrastructures. | WEN Guanghui YU Wenwu YU Xinghuo Lü Jinhu | 2017 | Journal of Systems Science & Complexity2017，30，1： | 11 |
| 8 | Effects of Different Land-Use Types on Soil Erosion Under Natural Rainfall in the Loess Plateau, China显示文摘黄土高原,位于中国的干旱、半干旱的区域,由于强烈人的活动和土壤 erodibility 经历重要土壤侵蚀。探索并且识别能控制土壤侵蚀并且完成某些农业生产能力的陆地使用类型或陆地使用模式是必要的。这研究在 Yan'an 的北方与二个斜坡坡度(5 °

| 10 | Multi-component LFM signal detection and parameter estimation based on Radon-HHT显示文摘A new method is proposed to analyze multi-component linear frequency modulated (LFM) signals, which eliminates cross terms in conventional Wigner-Ville distribution (WVD).The approach is based on Radon transform and Hilbert-Huang transform (HHT),which is a recently developed method adaptive to non-linear and non-stationary signals.The complicated signal is decomposed into several intrinsic mode functions (IMF) by the empirical mode decomposition (EMD),which makes the consequent instantaneous frequency meaningful.After the instantaneous frequency and Hilbert spectrum are computed,multi-component LFM signals detection and parameter estimation are obtained using Radon transform on the Hilbert spectrum plane.The simulation results show its feasibility and effectiveness. | Chen Wenwu Chen Rushan | 2008 | Journal of Systems Engineering and Electronics2008，19，6： | 9 |
| 11 | Prioritizing sustainable development goals and linking them to ecosystem services:A global expert’s knowledge evaluation显示文摘The implementation of strategies to achieve the Sustainable Development Goals(SDGs)is frequently hindered by potential trade-offs between priorities for either environmental protection or human well-being.However,ecosystem services(ES)-based solutions can offer possible co-benefits for SDGs implementation that are often overlooked or underexploited.In this study,we cover this gap and investigate how experts from different countries value the SDGs and relate them with ES.A total of 66 countries participated to the survey,and answers were grouped into three macro-regions:Asia;Europe,North America,and Oceania(ENO);Latin America,Caribbean and Africa(LA).Results show that the most prioritized SDGs in the three macro-regions are usually those related to essential material needs and environmental conditions,such as SDG2(Zero Hunger),SDG1(No Poverty),and SDG6(Clean Water).At a global scale,the number of prioritized synergies between SDGs and ES largely exceeded trade-offs.The highest amount of synergies was observed for SDG1(No Poverty),mainly with SDG2,SDG3(Good Health),SDG5(Gender Equality),and SDG8(Economic Growth).Other major synergies among SDGs include SDG14-15(Life below water-Life on land),SDG5-10(Gender Equity-Reduced Inequality),and SDG1-2(No poverty-Zero Hunger).At a global scale,SDG15,SDG13,SDG14,and SDG6 were closely related to ES like climate regulation,freshwater,food,water purification,biodiversity,and education.SDG11(Sustainable Cities)and SDG3 were also relevant in Asia and in LA,respectively.Overall,this study shows the potential to couple future policies that can implement SDGs’strategies while adopting ES-based solutions in different regions of the world. | Siqi Yang Wenwu Zhao Yanxu Liu Francesco Cherubini Bojie Fu Paulo Pereira | 2020 | Geography and Sustainability2020，1，4： | 9 |
| 12 | Significance of Shale Gas Development显示文摘Natural gas production from shale formations is growing exponentially in the United States. This paper introduces the five major shale formations in the United States and the technologies used to produce them. The Barnett, Haynesville, Fayetteville, Woodford, and Marcellus combined hold an estimated 978 trillion cubic feet of total gas reserves. These findings along with recent technological advances in horizontal drilling and completion methods have transformed the natural gas exploration and production industry in the U.S. and have fundamentally changed the U.S. energy picture. Specifically this paper states that the United States through the utilization of natural gas from shale can reduce its carbon emissions and can become more energy self-sufficient. Finally, the Harding & Shelton Group states in this paper that the opportunity to locate and produce shale gas in China is very similar to that which has taken place in the United States. | John Shelton Mike D.

| 13 | A GIS-based Spatial Analysis of Housing Price and Road Density in Proximity to Urban Lakes in Wuhan City, China显示文摘As one of the essential urban open spaces, lakes usually contribute immensely to the quality of residents′ daily lives. Different from hedonic approach employed in existing researches on urban open spaces in China, this paper integrates housing price surface with road density to analyze the spatial characteristics in proximity to urban lakes in Wuhan City, China. With the expansion of Wuhan City, urban lakes became polluted, they shrunk or even disappeared, leading to unfavorable conditions for sustainable development of the city. To better understand the spatial relationship between the city and lakes, we classify the urban lakes in Wuhan central area into ′lakes in the urban center′ and ′lakes in urban fringe′. Based on housing price surface we explore the spatial characteristics in proximity to different lakes and differences between the lakes. We also use Geographic Information System(GIS) tool to calculate road density as a supplementary indicator to reflect the accessibility in proximity to urban lakes. The results indicate that relative independence exists between different towns, and the spatial characteristics are different depending on scales and locations. In most of cases, the road density is lower where closer to the lakeshore while the housing price exhibits an opposite pattern. We conclude that city governments and urban planners should give more considerations to these spatial differences, somewhere should be better planned and protected as an important waterfront and somewhere the control of unreasonable real estate development nearby should be strengthened. | ZHANG Zuo TAN Shukui TANG Wenwu | 2015 | Chinese Geographical Science2015，25，6： | 8 |
| 14 | Integrate ecosystem services into socio-economic development to enhance achievement of sustainable development goals in the post-pandemic era显示文摘The COVID-19 pandemic has stalled and rolled back progress on Sustainable Development Goals(SDGs).Ecosys-tem services(ESs),defined as the contributions of ecosystems to human well-being,underpin the achievement of SDGs.To promote SDG achievement in post-pandemic era,we teased out the links between ESs and SDGs while examining the impact of COVID-19.We found that ESs benefited all SDGs,yet man-made pressures led to degra-dation of ecosystems and their services.There is broad consensus that the virus lurks in degraded ecosystems and generates spillover due to human interference.The pandemic and global lockdown/restriction disrupted the flow of ESs and altered human ESs demand,threatening the efforts for the SDGs.We suggested:1)to study the association and traceability of ESs-SDGs under the pandemic;2)to prioritize pressing issues such as health care,livelihood,and resource security and in the long run,we should promote human-nature harmony to achieve the SDGs;and 3)to enhance ESs and to promote the SDGs through local community efforts,ESs accounting,and ecosystem restoration.This paper provides insights into the importance of ESs to the SDGs and the ways to integrate ESs into socio-economic development to promote the SDG achievement after the pandemic. | Caichun Yin Wenwu Zhao Francesco Cherubini Paulo Pereira | 2021 | Geography and Sustainability2021，2，1： | 8 |
| 15 | Shale Gas Well Completions and Maximizing Gas Recoveries显示文摘It is shown that stress fields within the earth are the principle control for hydraulic fracture direction in horizontal shale gas wells. Hydraulic fracturing is a process of increasing permeability within gas shales and involves a sophisticated organization of technology, good planning and proper management of equipment over a very short time period to be successful. The direction and extent of the induced fractures can be determined in near real-time at the well site via application of earthquake seismology theory in a now common process known as frac mapping. Next to the horizontal lateral azimuth, the total volume of slurry pumped into the well is a major factor in determining well EURs. Vertical fracture growth can be controlled and is important in concentration of the slurry within the main zone target zone that has the high TOC and porosity. Cemented casing with perforations is currently the most used method for zone isolation. New open-hole sleeve packers may eventually provide more flexibility in fracture design while also providing a means for refracturing multi-stage fractured horizontal wells, a technique not now commonly available. Multi-Stage fracture design requires incorporating rock properties with fracturing effect simulations and then verifying results using 3D reservoir simulations. Maximizing the gas recovery factors and EURs can be accomplished through use of closely spaced laterals with inter-fingered fracture stages and exploiting the stress shadow fracturing phenomenon. Even greater EURs may be possible if the wells can be refractured thereby opening up additional permeability channels. Shale gas development has progressed in an environmentally sensitive manner within the U.S. and will continue in this manner. During the past ten years, all of these technologies have been either newly developed or were the advancement of existing technology with modifications. The opportunity exists to take these proven technologies to other areas of the world for exploitation of shale gas reservoirs. | Michael D.

| 17 | New Developments and Perspectives in Physical Geography in China显示文摘Physical geography is the cornerstone of geography. In this article, the starting points of disciplines in physical geography in recent years in China are discussed. With the coupling of systems set as the research object, and sustainable development as the ultimate goal, the upgrade of physical geography can be deconstructed into three steps: deepen physical geography from the perspective of pattern-process coupling, improve the focus of physical geography from ecosystem processes to ecosystem services, and increase the understanding of the physical geography ‘pattern, process, service, sustainability' research cascade. The incorporation of human activities into physical geographic processes is essential to conduct integrated analysis on physical and human factors at different scales. The development of ecosystem service models that couple supply-demand and sustainable development are of great importance to bridge the role of ecosystem services between the natural environment and human well-being. Moreover, human-land systems and sustainable development have become the core areas and frontiers of integrated physical geography and even geography in general. China faces the great strategic demand of constructing an ecological civilization in a new era, and the development of the disciplines of physical geography should give full access to the advantages of intersecting and comprehensive disciplines, focus on the human-land system patterns,processes, and services in key research areas, and provide disciplinary support for regional, national, and global sustainable development. | FU Bojie TIAN Tao LIU Yanxu ZHAO Wenwu | 2019 | Chinese Geographical Science2019，29，3： | 8 |
| 18 | Effect of illumination intensity and light application time on secondary organic aerosol formation from the photooxidation of α-pinene显示文摘Secondary organic aerosol (SOA) formation from hydroxyl radical (OH.) initiated photooxidation of α-pinene was investigated in a home-made smog chamber. The size distribution of SOA particles was measured using aerodynamic particle sizer spectrometer. The effects of illumination intensity and light application time on SOA formation for α-pinene were evaluated. Experimental results show that the concentration of SOA particles increased significantly with an increasing of illumination intensity, and the light application time, the concentration, and the size of SOA particles were also increased. In addition, the factors influencing the formation of SOA were discussed. In addition, this article compared the effect of α-pinene with that of toluene, and discussed the contribution of α-pinene to SOA formation. | LIU Xianyun, ZHANG Weijun, HUANG Mingqiang, WANG Zhenya, HAO Liqing, ZHAO Wenwu Laboratory of Environment Spectroscopy, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences,Hefei 230031, China. | 2009 | Journal of Environmental Sciences2009，21，4： | 7 |
| 19 | Short-term power load forecasting using integrated methods based on long short-term memory显示文摘The development of power system informatization,the massive access of distributed power supply and electric vehicles have increased the complexity of power consumption in the distribution network,which puts forward higher requirements for the accuracy and stability of load forecasting.In this paper,an integrated network architecture which consists of the self-organized mapping,chaotic time series,intelligent optimization algorithm and long short-term memory(LSTM)is proposed to extend the load forecasting length,decrease artificial debugging,and improve the prediction precision for the short-term power load forecasting.Compared with LSTM prediction,the algorithm in this paper improves the prediction accuracy by 61.87%in terms of root mean square error(RMSE),and reduces the prediction error by 50%in the 40-fold forecast window under some circumstances. | ZHANG WenJie QIN Jian MEI Feng FU JunJie DAI Bo YU WenWu | 2020 | Science China(Technological Sciences)2020，63，4： | 7 |
| 20 | Source-sink landscape theory and its ecological significance显示文摘Exploring the relationships between landscape pattern and ecological processes is the key topic of landscape ecology,for which,a large number of indices as well as landscape pattern analysis model were developed.However,one problem faced by landscape ecologists is that it is hard to link the landscape indices with a specific ecological process.Linking landscape pattern and ecological processes has become a challenge for landscape ecologists.“Source”and“sink”are common concepts used in air pollution research,by which the movement direction and pattern of different pollutants in air can be clearly identified.In fact,for any ecological process,the research can be considered as a balance between the source and the sink in space.Thus,the concepts of“source”and“sink”could be implemented to the research of landscape pattern and ecological processes.In this paper,a theory of sourcesink landscape was proposed,which include:(1)In the research of landscape pattern and ecological process,all landscape types can be divided into two groups,“source”landscape and“sink”landscape.“Source”landscape contributes positively to the ecological process,while“sink”landscape is unhelpful to the ecological process.(2)Both landscapes are recognized with regard to the specific ecological process.“Source”landscape in a target ecological process may change into a“sink”landscape as in another ecological process.Therefore,the ecological process should be determined before“source”or“sink”landscape were defined.(3)The key point to distinguish“source”landscape from“sink”landscape is to quantify the effect of landscape on ecological process.The positive effect is made by“source”landscape,and the negative effect by“sink”landscape.(4)For the same ecological process,the contribution of“source”landscapes may vary,and it is the same to the“sink”landscapes.It is required to determine the weight of each landscape type on ecological processes.(5)The sourcesink principle can be applied to non-point source pollution control,biologic diversity protection,urban heat island effect mitigation,etc.However,the landscape evaluation models need to be calibrated respectively,because different ecological processes correspond with different source-sink landscapes and evaluation models for the different study areas.This theory is helpful to further study landscape pattern and ecological process,and offers a basis for new landscape index design. | Liding CHEN Bojie FU Wenwu ZHAO | 2008 | Frontiers in Biology2008，3，2： | 6 |
