| 1 | A computational cognition model of perception,memory,and judgment显示文摘The mechanism of human cognition and its computability provide an important theoretical foundation to intelligent computation of visual media.This paper focuses on the intelligent processing of massive data of visual media and its corresponding processes of perception,memory,and judgment in cognition.In particular,both the human cognitive mechanism and cognitive computability of visual media are investigated in this paper at the following three levels:neurophysiology,cognitive psychology,and computational modeling.A computational cognition model of Perception,Memory,and Judgment(PMJ model for short)is proposed,which consists of three stages and three pathways by integrating the cognitive mechanism and computability aspects in a unified framework.Finally,this paper illustrates the applications of the proposed PMJ model in five visual media research areas.As demonstrated by these applications,the PMJ model sheds some light on the intelligent processing of visual media,and it would be innovative for researchers to apply human cognitive mechanism to computer science. | FU XiaoLan CAI LianHong LIU Ye JIA Jia CHEN WenFeng YI Zhang ZHAO GuoZhen LIU YongJin WU ChangXu | 2014 | Science China(Information Sciences)2014，57，3： | 10 |
| 2 | Mechanism of diagenetic trap formation in nearshore subaqueous fans on steep rift lacustrine basin slopes—A case study from the Shahejie Formation on the north slope of the Minfeng Subsag, Bohai Basin, China显示文摘Diagenetic traps in conglomerate in nearshore subaqueous fans in the steep slope zones of rift basins have been important exploration targets for subtle reservoirs in eastern China. However, the mechanism of how those traps were formed is not clear, which inhibits further exploration for this type of reservoir. In order to solve the problem, we take as an example nearshore subaqueous fans in the upper part of the fourth member of the Shahejie Formation(Es4s) on the north slope of the Minfeng Subsag in the Dongying Sag. Combining different research methods, such as core observation, thin section examination, scanning electron microscope(SEM) observation, fluid-inclusion analysis, carbon and oxygen isotope analysis of carbonate cements, and analysis of core properties, we studied the genetic mechanisms of diagenetic traps on the basis of diagenetic environment evolution and diagenetic evolution sequence in different sub/micro-facies. Conglomerate in Es4 s in the north Minfeng Subsag experienced several periods of transition between alkaline and acidic environments as 'alkaline–acidic–alkaline–acidic–weak alkaline'. As a result, dissolution and cementation are also very complex, and the sequence is 'early pyrite cementation / siderite cementation / gypsum cementation / calcite and dolomite cementation——feldspar dissolution / quartz overgrowth——quartz dissolution / ferroan calcite cementation / ankerite cementation / lime-mud matrix recrystallization / feldspar overgrowth——carbonate dissolution / feldspar dissolution / quartz overgrowth / pyrite cementation'. The difference in sedimentary characteristics between different sub/micro-facies of nearshore subaqueous fans controls diagenetic characteristics. Inner fan conglomerates mainly experienced compaction and lime-mud matrix recrystallization, with weak dissolution, which led to a reduction in the porosity and permeability crucial to reservoir formation. Lime-mud matrix recrystallization results in a rapid decrease in porosity and permeability in inner fan conglomerates in middle-to-deep layers. Because acid dissolution reworks reservoirs and hydrocarbon filling inhibits cementation, reservoirs far from mudstone layers in middle fan braided channels develop a great number of primary pores and secondary pores, and are good enough to be effective reservoirs of hydrocarbon. With the increase of burial depth, both the decrease of porosity and permeability of inner fan conglomerates and the increase of the physical property difference between inner fans and middle fans enhance the quality of seals in middle-to-deep layers. As a result, inner fan conglomerates can be sealing layers in middle-to-deep buried layers. Reservoirs adjacent to mudstones in middle fan braided channels and reservoirs in middle fan interdistributaries experienced extensive cementation, and tight cemented crusts formed at both the top and bottom of conglomerates, which can then act as cap rocks. In conclusion, diagenetic traps in conglomerates of nearshore subaqueous fans could be developed with inner fan conglomerates as lateral or vertical sealing layers, tight carbonate crusts near mudstone layers in middle fan braided channels as well as lacustrine mudstones as cap rocks, and conglomerates far from mudstone layers in middle fan braided channels as reservoirs. Lime-mud matrix recrystallization of inner fan conglomerates and carbonate cementation of conglomerates adjacent to mudstone layers in middle fan braided channels took place from 32 Ma B.P. to 24.6 Ma B.P., thus the formation of diagenetic traps was from 32 Ma B.P. to 24.6 Ma B.P. and diagenetic traps have a better hydrocarbon sealing ability from 24 Ma B.P.. The sealing ability of inner fans gradually increases with the increase of burial depth and diagenetic traps buried more than 3,200 m have better seals. | Wang Yanzhong Cao Yingchang Ma Benben Liu Huimin Gao Yongjin Chen Lin | 2014 | Petroleum Science2014，11，4： | 9 |
| 3 | Rb and Sr Geochemical Characterization of the Chinese Loess Stratigraphy and Its Implications for Palaeomonsoon Climate显示文摘Concentrations and distributions of Rb and Sr in loess and palaeosol samples from the Luochuan profile have been studied, in grain-size fractions and chemical forms. Results show that Rb is quite rich in the fraction of less than 2μm, and exits only in the residual phase, while Sr is distributed in sand and silt fractions, occurring in the residual and carbonate phases. Therefore, variations of the concentrations of Rb and Sr in loess and palaeosols are closely related not only to dustfall compositions depending on winter monsoon wind strength but also to summer monsoon-induced pedogenic intensity. This indicates that variations of Rb/Sr ratio in Chinese loess sequences represent cyclic alternations of East Asian summer and winter monsoon climates on the orbital time-scale. Variations in Sr concentrations along the sequence bear a high similarity to the oxygen isotope record of the deep sea sediments over the past 2.5 Ma, whereas variations in Rb concentrations are in good agreement with the record | CHEN Jun WANG Yongjin CHEN Yang LIU Lianwen JI Junfeng LU Huayu | 2000 | Acta Geologica Sinica(English Edition)2000，74，2： | 8 |
| 4 | A high-resolution stalagmite O-C isotope record from Nanjing and its rapid response to climatic events显示文摘Here we discussed rapid response of the cave temperature and vegetation to the four Dansgaard-Oeschger cold and warm cycles during 50-40 kaBP based on results of oxygen and carbon stable isotopic compositions from a stalagmite in Tangshan, Nanjing. It is found that the amount of C3 vegetation relative to C4-type declines during the D-O warm events, indicating the decrease of the effective mete-oric precipitation. Compared with O-isotope records of the Greenland ice core, the stalagmite record displays a very similar pattern to Greenland ice core record over the dec-ade-century time scale, suggesting that the changes of the East Asian monsoon climate are in accordance with the high-latitude polar climate in the short-term time scale. The age of the ice-rafted H5 event in the stalagmite record, how-ever, preceded that of Greenland ice cores by 2 ka. This out of phase between the remote areas cannot be yet proven be-cause the two time scales were determined from different dating methods. | WU Jiangying WANG Yongjin CHENG Hai CHEN Jun | 2002 | Chinese Science Bulletin2002，47，2： | 7 |
| 5 | Perovskite light-emitting/detecting bifunctional fibres for wearable LiFi communication显示文摘Light fidelity(LiFi),which is emerging as a compelling technology paradigm shifting the common means of highcapacity wireless communication technologies,requires wearable and full-duplex compact design because of its great significance in smart wearables as well as the‘Internet of Things’.However,the construction of the key component of wearable full-duplex LiFi,light-emitting/detecting bifunctional fibres,is still challenging because of the conflicting process between carrier separation and recombination,as well as the highly dynamic film-forming process.Here,we demonstrate light-emitting/detecting bifunctional fibres enabled by perovskite QDs with hybrid components.The hybrid perovskite inks endow fibres with super-smooth QD films.This,combined with the small exciton binding energy and high carrier mobility of perovskite QDs,enables successful integration of electroluminescence and photodetection into monofilaments.The bifunctional fibres possess the narrowest electroluminescence full width at half maximum of ~19 nm and,more importantly,the capability for simultaneously transmitting and receiving information.The successful fabrication of narrow emission full-duplex LiFi fibres paves the way for the fabrication and integration of low crosstalk interoperable smart wearables. | Qingsong Shan Changting Wei Yan Jiang Jizhong Song Yousheng Zou Leimeng Xu Tao Fang Tiantian Wang Yuhui Dong Jiaxin Liu Boning Han Fengjuan Zhang Jiawei Chen Yongjin Wang Haibo Zeng | 2020 | Light(Science & Applications)2020，9，1： | 7 |

| 8 | Understanding of the sodium storage mechanism in hard carbon anodes显示文摘Hard carbon has been regarded as the most promising anode material for sodiumion batteries(SIBs)due to its low cost,high reversible capacity,and low working potential.However,the uncertain sodium storage mechanism hinders the rational design and synthesis of high-performance hard carbon anode materials for practical SIBs.During the past decades,tremendous efforts have been put to stimulate the development of hard carbon materials.In this review,we discuss the recent progress of the study on the sodium storage mechanism of hard carbon anodes,and the effective strategies to improve their sodium storage performance have been summarized.It is anticipated that hard carbon anodes with high electrochemical properties will be inspired and fabricated for large-scale energy storage applications. | Xiaoyang Chen Changyu Liu Yongjin Fang Xinping Ai Faping Zhong Hanxi Yang Yuliang Cao | 2022 | Carbon Energy2022，4，6： | 3 |
| 9 | Distribution Features of the Nanhua-Sinian Rifts and their Significance to Hydrocarbon Accumulation in the Tarim Basin显示文摘On the basis of reprocessing 34 new two-dimensional spliced long sections(20,191 km) in the Tarim Basin, the deep structure features of the Tarim Basin were analyzed through interpreting 30,451 km of two-dimensional seismic data and compiling basic maps. Seismic interpretation and geological analysis conclude that the Nanhua-Sinian strata are a set of rift-depression depositional systems according to their tectonic and depositional features. The rift valley formed in the Nanhua Period, and the transformation became weaker during the late Sinian Period, which eventually turned into depression. From bottom to top, the deposited strata include mafic igneous, tillite, mudstone, and dolomite. Three major depocenters developed inside this basin during the rift stage and are distributed in the eastern Tarim Basin, the Awati area, and the southwestern Tarim Basin. Among them, the rift in the eastern Tarim Basin strikes in the near east-west direction on the plane and coincides with the aeromagnetic anomaly belt. This represents a strong magnetic zone formed by upwelling basic volcanic rock along high, steep normal faults of the Nanhua Period. Controlled by the tectonic background, two types of sedimentary systems were developed in the rift stage and depression stage, showing two types of sequence features in the Sinian depositional stage. The Nanhua System appears as a wedge-shaped formation, with its bottom in unconformable contact with the base. The rifting event has a strong influence on the current tectonic units in the Tarim Basin, and affects the distribution of source rock in the Yuertus Formation and reservoir beds in the Xiaoerbulake Formation in Lower Cambrian, as well as the gypseous cap rock in Middle Cambrian. The distribution features of the rifts have important and realistic significance for determining the direction of oil and gas exploration in the deep strata of the Tarim Basin. Comprehensive analysis suggests that the Tazhong region is the most favorable zone, and the Kalpin-Bachu region is the optimal potential zone for exploring sub-salt oil and gas in deep Cambrian strata. | BAI Zhongkai CHENG Minghua CHEN Cheng HUO Junzhou ZHANG Junfeng ZHOU Xingui GAO Yongjin ZHAO Bo QIU Haijun HAN Miao YANG Youxing SUN Zhichao MIAO Miaoqing ZHANG Jinhu LI Qingyao | 2020 | Acta Geologica Sinica(English Edition)2020，94，2： | 3 |
| 10 | Paleocurrent Analysis on the Basal Conglomerate of the Model Changzhougou Formation in Qian'an显示文摘The paleoflow direction of the basal conglomerate of the Changzhougou formation is obtained by the paleocurrent analysis of certain sedimentary structures, and the ancient sedimentary environment of the Qian'an Region is determined by observing the psephicity and gradation of gravel in conglomerate. The results show that the paleoflow direction is from northwest to southwest, and the paleocurrent data manifest a single-peak style in a rose diagram. The average paleoflow direction in the Qian'an region is 265°. The basal conglomerate is of littoral facies, and the sediments of conglomerates are mainly sourced from Shanhaiguan. | XIAO Junwen WU Fadong CHEN Yongjin | 2016 | Wuhan University Journal of Natural Sciences2016，21，2： | 3 |
| 11 | Joint synchronization estimation based on genetic algorithm for OFDM/OQAM systems显示文摘This paper investigates the problem of synchronization for offset quadrature amplitude modulation based orthogonal frequency division multiplexing(OFDM/OQAM) systems based on the genetic algorithm. In order to increase the spectrum efficiency,an improved preamble structure without guard symbols is derived at first. On this basis, instead of deriving the log likelihood function of power spectral density, joint estimation of the symbol timing offset and carrier frequency offset based on the preamble proposed is formulated into a bivariate optimization problem. After that, an improved genetic algorithm is used to find its global optimum solution. Conclusions can be drawn from simulation results that the proposed method has advantages in the joint estimation of synchronization. | LIU Yongjin CHEN Xihong ZHAO Yu | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 3 |
| 12 | Preparation and optical properties of three-dimensional navel-like Bi_2WO_6 hierarchical microspheres显示文摘Three-dimensional(3D) navel-like Bi_2WO_6(BWO) hierarchical microspheres(HMSs) were successfully prepared using a simple hydrothermal method. The as-obtained BWO samples were characterized by a variety of techniques. XRD result indicated that the as-synthesized samples were well-crystallized orthorhombic phase Bi_2WO_6 structure. SEM observations revealed that the hierarchical microspheres with an average diameter of 2 μm were built from several dozen of nanosheets. UV-vis diffuse reflectance spectrum study revealed that the obtained BWO sample had band gap energy of about 3.3 eV.Photoluminescence(PL) result showed that the sample had weak emission intensity. The BET specific surface area of the BWO sample was about 35.40 m^2/g. The photocatalytic efficiency of the as-obtained BWO was evaluated by the degradation of norfloxacin(NOR) antibiotic. The result showed an about 67%NOR degradation in 8 h. | Qiang Chen Yuqin Mao Naici Bing Yongjin Zou Luping Zhu | 2019 | Chinese Chemical Letters2019，30，3： | 1 |

| 15 | Multiscale analysis of Asian Monsoon over the past 640 ka显示文摘The empirical mode decomposition(EMD) method is used to re-analyse the high-resolution and precisely-dated stalagmite record from Chinese caves over the past 640 ka. Results show that(1) the variation in the Asian Monsoon can be completely decomposed into ten quasiperiod oscillations, among which the precession and semiprecession band oscillations are the most prominent periodicities, with contribution rates of 31.1% and 30.7%, respectively;(2) the cross-spectrum analysis of the semiprecession component and bi-hemisphere insolation(BHI) are strongly correlated, indicating an amplified response of precipitation and temperature variability to the interhemispheric insolation in the low-latitude regions, thus further affecting the intensity of the Asian Monsoon;(3) on millennial timescales, obvious oscillations at the 5 ka and 1–2 ka bands roughly correspond to the classical Bond and Dansgaard-Oeschger(DO) cycles. Additionally, a strong correlation is found between the detrended stalagmite δ18 O records and Ca/Sr sequence from the North Atlantic(especially at the 5 ka band). This result means that the 5 ka cycle is characteristic of the glacial-interglacial cycle since the middle and late Pleistocene and may imply that climate change on the millennial timescale is the result of an interaction between global ice volume and insolation. | Yalan ZENG Shitao CHEN Shaohua YANG Yijia LIANG Yongjin WANG | 2019 | Science China Earth Sciences2019，62，5： | 1 |
