| 1 | Magnetism parameters characteristics of drilling deposits in Jianghan Plain and indication for forming of the Yangtze River Three Gorges显示文摘The forming time of the Yangtze River Three Gorges is considered as one of keys in the research on the Yangtze River,also is one of the most disputed hotspots.In order to solve the difficult problem,the authors adopt the internationally recognized thoughts and methods of substance tracing from source to sink.The lithologic characteristics,magnetic parameters and magnetic mineral characteristics of deposits in 2 bores are analyzed,which are both sampled from the sedimentary center of the Jianghan Plain.The results are as follows:At about 110 m depth of the core,the contents of coarse materials and stable magnetic mineral both increase significantly.Meanwhile,the magnetic susceptibility of sediment,saturation isothermal remanent magnetization and magnetic susceptibility values of anhysteretic remanent magnetism increase suddenly,which all reflect that at about 110 m depth,the important adjustment has appeared in water system of the Jianghan Plain,and the sedimentary environment and material composition have changed greatly.And it may be the horizon where the Yangtze River Three Gorges formed,its forming time reflected by the paleomagnetic dating is between 1.17 and 1.12Ma B.P. | ZHANG YuFen LI Chang'An WANG QiuLiang CHEN Liang Ma YongFa KANG ChunGuo | 2008 | Chinese Science Bulletin2008，53，4： | 34 |
| 2 | Targeted Mutagenesis of NAC Transcription Factor Gene,OsN AC041,Leading to Salt Sensitivity in Rice显示文摘Salinity is a major abiotic stress factor that seriously affects plant growth. Many genes are involved in the response to salt stress with various metabolism pathways. A number of plant transcription factor family genes have been found to be involved in the salt stress response, and NAM, ATAF and CUC(NAC) transcription factors are thought to act as active regulators during abiotic stress, especially salt stress. In this study, we detected a rice NAC transcription factor coding gene, OsNAC041, and confirmed that it influenced the germination of seeds under salt stress and salt tolerance of plants. OsNAC041 was primarily expressed in the leaves and located in the nucleus. Furthermore, the CRISPR/Cas9 method was used to obtain a targeted osnac041 mutant, of which the plant height was higher than that of the wild-type, showing increased salt sensitivity. Moreover, RNA-seq analysis revealed a number of differentially expressed genes(DEGs) involved in several important signaling pathways in the osnac041 mutant. Subsequently, Kyoto Encyclopedia of Genes and Genomes annotation also revealed differential expression of DEGs associated with mitogen-activated protein kinase signaling, peroxisome, eukaryotictype ABC transporters, photosynthesis and plant hormones, which are involved in stress-related signaling pathways. Overall, our study suggested that OsNAC041 was involved in the salt stress response in rice. These findings not only provide empirical evidence of OsNAC041 function, but also provide new insight into its potential application in rice resistance breeding. | WANG Bo ZHONG Zhaohui ZHANG Huanhuan WANG Xia LIU Binglin YANG Lijia HAN Xiangyan YU Deshui ZHENG Xuelian WANG Chunguo SONG Wenqin CHEN Chengbin ZHANG Yong | 2019 | Rice science2019，26，2： | 8 |
| 3 | Process and mechanism for oil and gas accumulation, adjustment and reconstruction in Puguang Gas Field, Northeast Sichuan Basin, China显示文摘With the discoveries of a series of large gas fields in the northeast of Sichuan Basin, such as Puguang and Longgang gas fields, the formation mechanism of the gas reservoir containing high H2S in the ancient marine carbonate formation in superposition-basin becomes a hot topic in the field of petroleum geology. Based on the structure inversion, numerical simulation, and geochemical research, we show at least two intervals of fluid transfer in Puguang paleo-oil reservoir, one in the forepart of late Indo-Chinese epoch to early Yanshan epoch and the other in the metaphase of early Yanshan epoch. Oil and gas accumulation occurred at Puguang structure through Puguang-Dongyuezhai faults and dolomite beds in reef and shoal facies in Changxing Formation (P2ch) - Feixianguan Formation (T1f) in the northwest and southwest directions along three main migration pathways, to form Puguang paleo-oil reservoir. Since crude oil is pyrolysised in the early stage of middle Yanshan epoch, Puguang gas reservoir has experienced fluid adjusting process controlled by tectonic movement and geochemical reconstruction process controlled by thermochemical sulfate reduction (TSR). Middle Yan-shan epoch is the main period during which the Puguang gas reservoir experienced the geochemical reaction of TSR. On one hand, TSR can recreate the fluid in gas reservoir, which makes the gas drying index larger and carbon isotope heavier. On the other hand, the reciprocity between fluid regarding TSR (hydrocarbon, H2S, and water) and reservoir rock induces erosion of the reservoir rocks and anhydrite alteration, which improves reservoir petrophysical properties. Superimposed by later tectonic movement, the fluid in Puguang reservoir has twice experienced adjustment, one in the late Yanshan epoch to the early Himalayan epoch and the other time in late Himalayan epoch, after which Puguang gas reservoir is finally developed. | DU ChunGuo HAO Fang ZOU HuaYao ZHU YangMing CAI XunYu WANG CunWu | 2009 | Science China Earth Sciences2009，52，9： | 6 |
| 4 | Draft genome sequence of cauliflower(Brassica oleracea L.var.botrytis)provides new insights into the C genome in Brassica species显示文摘Cauliflower is an important variety of Brassica oleracea and is planted worldwide.Here,the high-quality genome sequence of cauliflower was reported.The assembled cauliflower genome was 584.60 Mb in size,with a contig N50 of 2.11 Mb,and contained 47,772 genes;56.65%of the genome was composed of repetitive sequences.Among these sequences,long terminal repeats(LTRs)were the most abundant(32.71%of the genome),followed by transposable elements(TEs)(12.62%).Comparative genomic analysis confirmed that after an ancient paleohexaploidy(γ)event,cauliflower underwent two whole-genome duplication(WGD)events shared with Arabidopsis and an additional whole-genome triplication(WGT)event shared with other Brassica species.The present cultivated cauliflower diverged from the ancestral B.oleracea species~3.0 million years ago(Mya).The speciation of cauliflower(~2.0 Mya)was later than that of B.oleracea L.var.capitata(approximately 2.6 Mya)and other Brassica species(over 2.0 Mya).Chromosome no.03 of cauliflower shared the most syntenic blocks with the A,B,and C genomes of Brassica species and its eight other chromosomes,implying that chromosome no.03 might be the most ancient one in the cauliflower genome,which was consistent with the chromosome being inherited from the common ancestor of Brassica species.In addition,2,718 specific genes,228 expanded genes,2 contracted genes,and 1,065 positively selected genes in cauliflower were identified and functionally annotated.These findings provide new insights into the genomic diversity of Brassica species and serve as a valuable reference for molecular breeding of cauliflower. | Deling Sun Chunguo Wang Xiaoli Zhang Wenlin Zhang Hanmin Jiang Xingwei Yao Lili Liu Zhenghua Wen Guobao Niu Xiaozheng Shan | 2019 | Horticulture Research2019，6，1： | 6 |
| 5 | Outage Probability Minimization for Low-Altitude UAV-Enabled Full-Duplex Mobile Relaying Systems显示文摘In this paper, a novel unmanned aerial vehicle(UAV)-enabled full duplex decode-and-forward(DF) technique is used in mobile relaying system. Compared with conventional static relaying, mobile relaying provides more degree of freedom for experiencing better channel conditions and further improving the system reliable performance. The source and relay transmit power as well as relay trajectory are jointly optimized for sum outage probability minimization in mobile relaying system. Due to the non-convex nature of the original problem, block coordinate decent optimization techniques are employed to decompose it into two sub-problems, which leads to an efficient iterative algorithm. Specifically, for the pre-determined relay trajectory, the optimal transmit power of source and relay are obtained by solving Karush-Kuhn-Tucker(KKT) conditions. For the given source/relay power allocation, the optimal UAV trajectory is obtained by solving dual problem. Based on the two steps, an iterative algorithm is proposed to jointly optimize source/relay power allocation and UAV trajectory alternately. Numerical results show the performance gain of our proposed scheme. | Meng Hua Yi Wang Zhengming Zhang Chunguo Li Yongming Huang Luxi Yang | 2018 | China Communications2018，15，5： | 5 |

| 7 | Changing provenance of late Cenozoic sediments in the Jianghan Basin显示文摘The Yangtze River is one of the most important components of the East Asia river system.In this study,sediments in the Jianghan Basin,middle Yangtze River,were selected for trace element and rare earth element(REE)measurements,in order to decipher information on the change of sediment provenance and evolution of the Yangtze River.According to the elemental variations,the late Cenozoic sediments of the Jianghan Basin could be divided into four parts.During 2.68e2.28 Ma and 1.25e0 Ma,provenance of the sediments was consistent,whereas sediments were derived from variable sources during2.28e1.25 Ma.Comparison of the elemental compositions between the Pliocene and Quaternary sediments revealed a change in sediment source from a more felsic source area to a more basic source area around the PlioceneeQuaternary boundary.Input from the Emeishan LIP should account for this provenance change.Based on the provenance analysis of sediments in the Jianghan Basin,we infer that the Yangtze River developed into a large river with its drainage basin extended to the Emeishan LIP no later than the PlioceneeQuaternary boundary. | Lei Shao Shengyuan Yuan Chang'an Li Chunguo Kang Wenjing Zhu Yindi Liu Jietao Wang | 2015 | Geoscience Frontiers2015，6，4： | 3 |
| 8 | The Numerical Simulation on Hollow Part's Precise Sizing Process With Cross-wedge Rolling显示文摘The hollow parts formed with cross-wedge rolling (CWR) have a wide application in many fields, such as architecture and automobile, etc. But the finished configuration of part’s cross section was always ellipse and it was hard to make it satisfied with traditional forming process. This paper proposed a FEM model of hollow workpiece of CWR in the sizing process, and simulated the deformation condition using the ANSYS program. Three kinds of parts with different wall thickness were calculated. Some stress and strain fields of the deformed hollow parts at various conditions are gained. The influence of wall thickness on the distribution of stress and strain was analyzed. The paper also found two phenomena, which never have been seen at traditional experiment, and author tried to give some explanations. The ANSYS program provided the relationship between the tolerance of the deformed workpiece and the deforming parameter. It is helpful to design the sizing dies of a new precise forming process of hollow parts on the CWR. The new process that designed through the information of FEM improved the accuracy of hollow parts on CWR. It proved the validity and practicability of numerical simulation. | Jingliang Wang, Chunguo Xu, Guangsheng Ren Beijing Research Institute of M./E.

| 9 | Structure and Fluid Transportation Performance of Faults in the Changxing-Feixianguan Formation, Xuanhan County, Northeastern Sichuan Basin显示文摘On the basis of field observations, microscopic thin-sections and laboratory data analysis of ten faults in Xuanhan County area, northeastern Sichuan Basin, central China, the internal and megascopic structures and tectonite development characteristics are mainly controlled by the geomechanical quality in brittle formation of the Changxing-Feixianguan Formation. The fluid transportation performance difference between the faults formed by different geomechanics or different structural parts of the same fault are controlled by the megascopic structure and tectonite development characteristics. For instance, the extension fault structure consists of a tectonite breccia zone and an extension fracture zone. Good fluid transportation performance zones are the extension fracture zone adjacent to the tectonite breccia zone and the breccia zone formed at the early evolutionary stage. The typical compression fault structure consists of a boulder-clay zone or zones of grinding gravel rock, compression foliation, tectonite lens, and dense fracture development. The dense fracture development zone is the best fluid transporting area at a certain scale of the compression fault, and then the lens, grinding gravel rock zone and compression foliation zones are the worst areas for hydrocarbon migration. The typical tensor-shear fault with a certain scale can be divided into boulder-clay or grinding gravel rock zones of the fault, as well as a pinnate fractures zone and a derivative fractures zone. The grinding gravel rock zone is the worst one for fluid transportation. Because of the fracture mesh connectivity and better penetration ability, the pinnate fractures zone provides the dominant pathway for hydrocarbon vertical migration along the tensor-shear fault. | DU Chunguo WANG Jianjun ZHANG Jun WANG Ping XUE Mei ZHOU Huayao | 2014 | Acta Geologica Sinica(English Edition)2014，88，3： | 2 |
| 10 | Diagenesis and Restructuring Mechanism of Oil and Gas Reservoir in the Marine Carbonate Formation,Northeastern Sichuan:A Case Study of the Puguang Gas Reservoir显示文摘Based on the technology of balanced cross-section and physical simulation experiments associated with natural gas geochemical characteristic analyses, core and thin section observations, it has been proven that the Puguang gas reservoir has experienced two periods of diagenesis and restructuring since the Late Indo-Chinese epoch. One is the fluid transfer controlled by the tectonic movement and the other is geochemical reconstruction controlled by thermochemical sulfate reduction (TSR). The middle Yanshan epoch was the main period that the Puguang gas reservoir experienced the geochemical reaction of TSR. TSR can recreate the fluid in the gas reservoir, which makes the gas drying index higher and carbon isotope heavier because C2+ (ethane and heavy hydrocarbon) and 12C (carbon 12 isotope) is first consumed relative to CH4 and 13C (carbon 13 isotope). However, the reciprocity between fluid regarding TSR (hydrocarbon, sulfureted hydrogen (H2S) , and water) and reservoir rock results in reservoir rock erosion and anhydrite alteration, which increases porosity in reservoir, thereby improving the petrophysical properties. Superimposed by later tectonic movement, the fluid in Puguang reservoir has twice experienced adjustment, one in the late Yanshan epoch to the early Himalayan epoch and the other time in late Himalayan epoch, after which Puguang gas reservoir is finally developed. | DU Chunguo WANG Jianjun ZOU Huayao ZHU Yangming WANG Cunwu | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 2 |
| 11 | Numerical Simulation of Axial Inflow Characteristics and Aerodynamic Noise in a Large-Scale Adjustable-Blade Fan显示文摘Numerical simulation are conducted to explore the characteristics of the axial inflow and related aerodynamic noise for a large-scale adjustable fan with the installation angle changing from−12°to 12°.In such a range the maximum static(gauge)pressure at the inlet changes from−2280 Pa to 382 Pa,and the minimum static pressure decreases from−3389 Pa to−8000 Pa.As for the axial intermediate flow surface,one low pressure zone is located at the junction of the suction surface and the hub,another is located at the suction surface close to the casing position.At the outlet boundary,the low pressure is negative and decreases from−1716 Pa to−4589 Pa.The sound pressure level of the inlet and outlet noise tends to increase monotonously by 11.6 dB and 7.3 dB,respectively.The acoustic energy of discrete noise is always higher than that of broadband noise regardless of whether the inlet or outlet flow surfaces are considered.The acoustic energy ratio of discrete noise at the inlet tends to increase from 0.78 to 0.93,while at the outlet it first decreases from 0.79 to 0.73 and then increases to 0.84. | Lin Wang Chunguo An Nini Wang Yaming Ping Kun Wang Ming Gao Suoying He | 2020 | Fluid Dynamics & Materials Processing2020，16，3： | 2 |

| 13 | Efficient Deployment of Multiple UAVs for IoT Communication in Dynamic Environment显示文摘The application of unmanned aerial vehicle(UAV)-mounted base stations is emerging as an effective solution to provide wireless communication service for a target region containing some smart objects(SOs)in internet of things(IoT).This paper investigates the efficient deployment problem of multiple UAVs for IoT communication in dynamic environment.We first define a measurement of communication performance of UAVto-SO in the target region which is regarded as the optimization objective.The state of one SO is active when it needs to transmit or receive the data;otherwise,silent.The switch of two different states is implemented with a certain probability that results in a dynamic communication environment.In the dynamic environment,the active states of SOs cannot be known by UAVs in advance and only neighbouring UAVs can communicate with each other.To overcome these challenges in the deployment,we leverage a game-theoretic learning approach to solve the position-selected problem.This problem is modeled a stochastic game,which is proven that it is an exact potential game and exists the best Nash equilibria(NE).Furthermore,a distributed position optimization algorithm is proposed,which can converge to a pure-strategy NE.Numerical results demonstrate the excellent performance of our proposed algorithm. | Haibo Dai Haiyang Zhang Chunguo Li Baoyun Wang | 2020 | China Communications2020，17，1： | 1 |
| 14 | Network pharmacology used to decode potential active ingredients in Ferula assafoetida and mechanisms for the application to Alzheimer’s disease显示文摘Background:Alzheimer’s disease(AD)is a neurodegenerative disease that primarily manifests as progressive memory loss and cognitive impairment.Traditional herbal medicines may be helpful in the discovery of new anti-AD drugs.Studies have shown that Ferula assafoetida has neuroprotective and memory-enhancing effects,which may be beneficial for the treatment of AD.However,the combination of active ingredients and their mechanisms remain unclear.Therefore,we aimed to identify potential active ingredients in F.assafoetida and their mechanisms of action against AD by using network pharmacology.Methods:In our study,an integrated network pharmacological approach,that included adsorption,distribution,metabolism and excretion screening,target identification,network construction,topological analysis,gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis,and molecular docking,was used to predict the pharmacological material basis and potential mechanisms through which these ingredients may treat and prevent AD.Results:The results indicated that 12 key active ingredients,obtained by topological analysis(including farnesiferol a,conferol,farnesiferol b,ferulic acid,etc.),may be the primary pharmacological components that may ameliorate AD.The 2 key significant pathways identified are the cholinergic synapse signaling pathway(critical targets include ACHE,CHRM1,CHRM2,MAPK1,PIK3CA,PIK3CB,PIK3CD,and PIK3CG)and the AD signaling pathway(critical targets include APP,BACE1,GSK3B,MAPK1,NCSTN,NOS1,PSEN1).These critical targets are closely related to the regulation of three typical pathological features of AD[central nervous system(CNS)cholinergic hypofunction,amyloid-β(Aβ)plaques,and hyperphosphorylated tau proteins].Finally,14 critical targets in the 2 key significant pathways were validated by molecular docking analysis.Conclusion:F.assafoetida may be effective for alleviating AD symptoms,through multi-component,multi-target,and multi-pathway synergistic effects,associated with the multiple pathogenesis hypotheses of AD.Our study may provide certain clues for the further development and utilization of this natural herbal medicine. | Meng Xu Lili Zhang Pin Li Chunguo Wang Yuanyuan Shi | 2020 | Journal of Traditional Chinese Medical Sciences2020，7，2： | 1 |

| 16 | Progress in Antarctic marine geophysical research by the Chinese Polar Program显示文摘Marine geophysical survey by the Chinese National Antarctic Research Expedition(CHINARE) began with the first science expedition in 1984/1985, although only four cruises were performed in the vicinity of the Antarctic Peninsula between then and 1991/1992. After a 20 year hiatus, Antarctic marine geophysical research was relaunched by the Chinese Polar Environmental Comprehensive Investigation and Assessment Programs(known simply as the Chinese Polar Program) in 2011/2012. Integrated geophysical surveys have been carried out annually since, in Prydz Bay and the Ross Sea. During the last 5 years, we have acquired about 5500 km of bathymetric, gravimetric, and magnetic lines; more than 1800 km of seismic reflection lines; and data from several heat flow and Ocean Bottom Seismometer(OBS) stations. This work has deepened understandings of geophysical features and their implications for geological tectonics and glacial history in Antarctica and its surrounding seas. Compiled Antarctic Bouguer and Airy isostatic gravity anomalies show different features of tectonics between the East Antarctic stability and West Antarctic activity. Calculated magnetic anomalies, heat flow anomalies and lithospheric anisotropy offshore of Prydz Bay may imply high heat capacity of mantle shielded by the continental shelf lithosphere, but high heat dissipation of mantle due to the Cretaceous breakup of Gondwana along the continent and ocean transition(COT), where large sediment ridges would be brought about by the Oligocene ice sheet retreat and would enlarge free-air gravity anomalies. In the western Ross Sea, CHINARE seismic profiles indicate northern termination of the Terror Rift and deposition time of the grounding zone wedge in the northern JOIDES Basin. | GAO Jinyao SHEN Zhongyan YANG Chunguo WANG Wei JI Fei WU Zhaocai NIU Xiongwei DING Weifeng LI Dongxu ZHANG Qiao | 2017 | Advances in Polar Science2017，28，4： | 1 |
| 17 | Optimal remote radio head selection for cloud radio access networks显示文摘The cloud radio access network(C-RAN) promises significant gain to the data rate over the LTEadvanced by transferring the burdensome baseband signal processing from the remote radio heads(RRHs) to the baseband unit via the front-haul. However, scalable improvement of the overall throughput may not be maintained due to limited front-haul capacity. In this paper, we study the throughput maximization problem by selecting the active RRHs. In particular, we develop an optimum algorithm which selects a subset of active RRHs that maximize the system throughput under the front-haul constraint. In addition, the asymptotically optimum number of RRHs is derived in closed-form for low and high signal-to-noise ratio(SNR) regimes. It is demonstrated that the proposed RRH selection scheme outperforms any other existing schemes with substantial gain of achievable throughput for any given number of RRHs and any predetermined front-haul capacity constraints. | Chunguo LI Kang SONG Dongming WANG Fu-Chun ZHENG Luxi YANG | 2016 | Science China(Information Sciences)2016，59，10： | 1 |
