| 1 | Centro-parietal N200: An event-related potential component specific to Chinese visual word recognition显示文摘Almost all written languages currently used in the world are alphabetic or phonologically-based scripts (e.g., English) whose word recognition involves discrimination of one-dimensional linear combinations of several dozens of letters or phonological units, except written Chinese whose vocabulary consists of a large number of block characters, the analysis of which relies on the extraction of 2-dimensional form information at multiple levels including radical, character, and multiple-character word. Whether the dramatic contrast between the 2 types of orthography leads to distinctive mental processes is a fundamental question in psycholinguistic research unanswered in the past three decades. Using event-related potentials and visual lexical decision tasks, we asked native Chinese speakers to discriminate between real Chinese words and pseudoor non-words and observed a widespread negative deflection with centro-parietal focus elicited 200 ms post-stimulus onset. This N200 response showed a clear and large amplitude enhancement upon word repetition and seems to be specific to Chinese as no similar effects had been reported in word recognition studies involving alphabetic scripts under similar experimental conditions. Further evidence showed that this N200 could not be attributed to non-linguistic sensori-perceptual processes, nor phonological or semantic processes, but likely reflects very early identification of the orthography of individual words involving extensive and higher-level visual analysis. Recently the first author proposed a meaning-spelling theory of written Chinese vocabulary proposing that the Chinese and alphabetic scripts are the only 2 possible logical types of mature human writing systems, and that the former is more thoroughly a visual language compared with the latter and thus shall emphasize more of visual processing. Reinforcing each other, the meaning-spelling theory and the discovery of the centro-parietal N200 reveal the uniqueness of Chinese both theoretically and empirically, and provide strong arguments for the intrinsic distinction between written Chinese and alphabetic scripts. | ZHANG John X FANG Zhuo DU YingChun KONG LingYue ZHANG Qin XING Qiang | 2012 | Chinese Science Bulletin2012，57，13： | 6 |
| 2 | Algebraic encoding scheme for aperture 3 hexagonal discrete global grid system显示文摘Discrete Global Grid Systems(DGGSs) are spatial references that use a hierarchical tessellation of cells to partition and address the entire globe. They provide an organizational structure that permits fast integration between multiple sources of large and variable geospatial data sufficient for visualization and analysis. Despite a significant body of research supporting hexagonal DGGSs as the superior choice, the application thereof has been hindered owing in part to the lack of a rational hierarchy with an efficient addressing system. This paper presents an algebraic model of encoding scheme for the Aperture 3 Hexagonal(A3H) DGGS. Firstly, the definition of a grid cell, which is composed of vertices, edges, and a center, is introduced to describe fundamental elements of grids. Secondly, by identifying the grid cell with its center, this paper proves that cell centers at different levels can be represented exactly using a mixed positional number system in the complex plane through the recursive geometric relationship between two successive levels, which reveals that grid cells are essentially special complex radix numbers. Thirdly, it is shown that through the recursive geometric relationship of successive odd or even levels, the mixed positional number system can also be applied to uniquely represent cell centers at different levels under specific constraint conditions, according to which the encoding scheme is designed. Finally, it is shown that by extending the scheme to 20 triangular faces of the regular icosahedron,multi-resolution grids on closed surfaces of the icosahedron are addressed perfectly. Contrast experiments show that the proposed encoding scheme has the advantages of theoretical rigor and high programming efficiency and that the efficiency of cross-face adjacent cell searching is 242.9 times that of a similar scheme. Moreover, the proposed complex radix number representation is an ideal formalized description tool for grid systems. The research ideas introduced herein can be used to create a universal theoretical framework for DGGSs. | BEN Jin LI YaLu ZHOU ChengHu WANG Rui DU LingYu | 2018 | Science China Earth Sciences2018，61，2： | 5 |

| 5 | A novel method of determining the optimal polyhedral orientation for discrete global grid systems applicable to regionalscale areas of interest显示文摘The polyhedral discrete global grid system(DGGS)is a multi-resolution discrete earth reference model supporting the fusion and processing of multi-source geospatial information.The orientation of the polyhedron relative to the earth is one of its key design choices,used when constructing the grid system,as the efficiency of indexing will decrease if local areas of interest extend over multiple faces of the spherical polyhedron.To date,most research has focused on global-scale applications while almost no rigorous mathematical models have been established for determining orientation parameters.In this paper,we propose a method for determining the optimal polyhedral orientation of DGGSs for areas of interest on a regional scale.The proposed method avoids splitting local or regional target areas across multiple polyhedral faces.At the same time,it effectively handles geospatial data at a global scale because of the inherent characteristics of DGGSs.Results show that the orientation determined by this method successfully guarantees that target areas are located at the center of a single polyhedral face.The orientation process determined by this novel method reduces distortions and is more adaptable to different geographical areas,scales,and base polyhedrons than those employed by existing procedures. | Jianbin Zhou Jin Ben Rui Wang Mingyang Zheng Xiaochuang Yao Lingyu Du | 2020 | International Journal of Digital Earth2020，13，12： | 2 |
| 6 | A universal spray printing strategy to prepare gradient hybrid architectures显示文摘Functionally gradient materials(FGMs)have attracted tremendous attention due to their unique properties and structures.However,it is still a great challenge to prepare scalable FGMs by a universal,cost-effective,and highly efficient method.Here,a strategy of combining in situ concentration regulation and spraying is developed to fabricate continuously gradient composite films(GCFs),where the component gradient variation can be well controlled.This strategy is universal and versatile,which is beneficial to inducing different components into GCFs with gradient distributions and further constructing them with diverse configurations on various substrates.The gradient design endows the composite films with excellent mechanical strength and gradient electron transport pathways,which ensures that GCFs directly serve as the electrodes in electrochemical devices.As a proof of concept,free-standing GCFs based on V2O5 nanomaterials are used as cathodes of aqueous zinc-ion batteries.The resultant devices deliver superior electrochemical performances in comparison with the counterparts of homogeneous case.Therefore,this universal strategy provides a promising route in the scalable production of FGMs and further extends their applications in various fields. | Lingyu Du Songshan Bi Yang Hu Rui Wang Jiacai Zhu Minghui Zhang Zhiqiang Niu | 2022 | Carbon Energy2022，4，4： | 2 |
| 7 | A review on the application of nanofluids in enhanced oil recovery显示文摘Enhanced oil recovery(EOR)has been widely used to recover residual oil after the primary or secondary oil recovery processes.Compared to conventional methods,chemical EOR has demonstrated high oil recovery and low operational costs.Nanofluids have received extensive attention owing to their advantages of low cost,high oil recovery,and wide applicability.In recent years,nanofluids have been widely used in EOR processes.Moreover,several studies have focused on the role of nanofluids in the nanofluid EOR(N-EOR)process.However,the mechanisms related to N-EOR are unclear,and several of the mechanisms established are chaotic and contradictory.This review was conducted by considering heavy oil molecules/particle/surface micromechanics;nanofluidassisted EOR methods;multiscale,multiphase pore/core displacement experiments;and multiphase flow fluid-solid coupling simulations.Nanofluids can alter the wettability of minerals(particle/surface micromechanics),oil/water interfacial tension(heavy oil molecules/water micromechanics),and structural disjoining pressure(heavy oil molecules/particle/surface micromechanics).They can also cause viscosity reduction(micromechanics of heavy oil molecules).Nanofoam technology,nanoemulsion technology,and injected fluids were used during the EOR process.The mechanism of N-EOR is based on the nanoparticle adsorption effect.Nanoparticles can be adsorbed on mineral surfaces and alter the wettability of minerals from oil-wet to water-wet conditions.Nanoparticles can also be adsorbed on the oil/water surface,which alters the oil/water interfacial tension,resulting in the formation of emulsions.Asphaltenes are also adsorbed on the surface of nanoparticles,which reduces the asphaltene content in heavy oil,resulting in a decrease in the viscosity of oil,which helps in oil recovery.In previous studies,most researchers only focused on the results,and the nanoparticle adsorption properties have been ignored.This review presents the relationship between the adsorption properties of nanoparticles and the N-EOR mechanisms.The nanofluid behaviour during a multiphase core displacement process is also discussed,and the corresponding simulation is analysed.Finally,potential mechanisms and future directions of N-EOR are proposed.The findings of this study can further the understanding of N-EOR mechanisms from the perspective of heavy oil molecules/particle/surface micromechanics,as well as clarify the role of nanofluids in multiphase core displacement experiments and simulations.This review also presents limitations and bottlenecks,guiding researchers to develop methods to synthesise novel nanoparticles and conduct further research. | Jinjian Hou Jinze Du Hong Sui Lingyu Sun | 2022 | Frontiers of Chemical Science and Engineering2022，16，8： | 1 |

| 9 | Neutral color and self-healable electrochromic system based on CuI/Cu and I_(3)^(-)/I^(-)conversions显示文摘The electrochromic(EC)mechanisms of inorganic materials are usually based on reversible cation insertion/extraction or metal deposition/dissolution,which are plagued by ion trapping and dendrite growth,respectively.In this paper,a novel conversion-type electrochromic mechanism is proposed,by making good use of the CuI/Cu redox couple.This CuI-based electrochromic system shows a neutral color switching from transparent and dim grey.By simply increasing the bleaching voltage,I_(3)^(-)/I^(-)redox couple can be further activated.The generated I_(3)^(-)will readily react with Cu,effectively improving the conversion reversibility and thereby rejuvenating the degraded electrochromic performance.Thanks to the well-designed electrode and the self-healing ability,this conversion electrochromic system achieves rapid response times(tcoloring:23 s,tbleaching:6 s),decant optical modulation amplitude(26.4%),high coloration efficiency(86.15 cm^(2)·C^(-1)),admirable cyclic durability(without performance degradation after 480 cycles)and excellent optical memory ability(transmittance variation<1%after 10 h open-circuit storage).The establishment of this conversion-type electrochromism may inspire the exploration of novel electrochromic materials and devices. | Junsen Zhong Bingkun Huang Kunjie Yang Zuju Ma Lingyu Du Ning Luo Fengjiao Tang Chuanxin Hou Fuyi Jiang Litao Kang | 2024 | Nano Research2024，17，5： | 0 |
| 10 | Phenome-wide association study and precision medicine of cardiovascular diseases in the post-COVID-19 era显示文摘SARS-CoV-2 infection causes injuries of not only the lungs but also the heart and endothelial cells in vasculature of multiple organs,and induces systemic inflammation and immune over-reactions,which makes COVID-19 a disease phenome that simultaneously affects multiple systems.Cardiovascular diseases(CVD)are intrinsic risk and causative factors for severe COVID-19 comorbidities and death.The wide-spread infection and reinfection of SARS-CoV-2 variants and the long-COVID may become a new common threat to human health and propose unprecedented impact on the risk factors,pathophysiology,and pharmacology of many diseases including CVD for a long time.COVID-19 has highlighted the urgent demand for precision medicine which needs new knowledge network to innovate disease taxonomy for more precise diagnosis,therapy,and prevention of disease.A deeper understanding of CVD in the setting of COVID-19 phenome requires a paradigm shift from the current phenotypic study that focuses on the virus or individual symptoms to phenomics of COVID-19 that addresses the inter-connectedness of clinical phenotypes,i.e.,clinical phenome.Here,we summarize the CVD manifestations in the full clinical spectrum of COVID-19,and the phenome-wide association study of CVD interrelated to COVID-19.We discuss the underlying biology for CVD in the COVID-19 phenome and the concept of precision medicine with new phenomic taxonomy that addresses the overall pathophysiological responses of the body to the SARS-CoV-2 infection.We also briefly discuss the unique taxonomy of disease as Zheng-hou patterns in traditional Chinese medicine,and their potential implications in precision medicine of CVD in the post-COVID-19 era. | Qian Cao Xin Du Xiao-yan Jiang Yuan Tian Chen-hao Gao Zi-yu Liu Ting Xu Xing-xing Tao Ming Lei Xiao-qiang Wang Lingyu Linda Ye Dayue Darrel Duan | 2023 | Acta Pharmacologica Sinica2023，44，12： | 0 |
