| 1 | Late Pleistocene glaciation of the Changbai Mountains in northeastern China显示文摘The Changbai Mountains (2749 m a.s.l.) in northeastern China are one of the typical mountain regions with glaciation since late Pleistocene as evidenced by well-preserved erosive and accumulative landforms at elevations above 2000 m a.s.l. formed by glaciers around the crater lake, Tianchi Lake. Cirque glaciers developed on both the inner and outer sides of the volcanic cone. Well-preserved cirques, glacial trough valleys, glacial threholds, polished surfaces of the glacial erratics and the moraine ridges indicate that several glaciation processes took place during the last glacial period in this region. Results of optically stimulated luminescence (OSL) dating on the moraine sediments, and the K/Ar, ther- mal ionization mass spectrometry (TIMS), electronic spinning resonance (ESR) dating on the volcanic rocks suggest two periods of glacier advances. One is named the Black Wind Mouth glacier advance taking place on the west and north slopes of the volcanic cone at an elevation of 2000―2100 m a.s.l., which is dated to about 20 ka, being the result of the Last Glacial Maximum (LGM). The other is named the Meteorological Station glacier advance at the elevation of 2400―2600 m a.s.l., dated to 11 ka during the late glacial period, and is tentatively correlated to the Younger Dryas stage. The scope of the former glacier advance is larger than that of the latter. Regional comparisons showed that the glacial sequences in the Changbai Mountains are similar to other glaciated areas in eastern Asia during the later part of the last glacial cycle. | ZHANG Wei NIU YunBo YAN Ling CUI ZhiJiu LI ChuanChuan MU KeHua | 2008 | Chinese Science Bulletin2008，53，17： | 18 |
| 2 | Joint land-sea seismic survey and research on the deep structures of the Bohai Sea areas显示文摘This paper presents the survey and research work of two land-sea profiles in the Bohai Sea,China,carried out in 2010–2011,including the seismic sources on land and in the sea,the ocean bottom seismographs(OBS)and their recovery,the coupling of OBS and the environment noise in sea area,the data quality of OBSs,and the result of data analysis.We focused on the investigation of crustal structures revealed by the two NE\EW-trending joint land-sea profiles.In combination with the Pn-velocity distribution and gravitymagnetic inversion results in the North China Craton,we propose that the undulation of the Moho interface in the Bohai and surrounding areas is not strong,and the lithospheric thinning is mainly caused by the thinning of its mantle part.The research result indicates that obvious lateral variations of Moho depth and seismic velocity appear nearby all the large-scale faults in Bohai Sea,and there is evidence of underplating and reforming of the lower crust by mantle material in the Bohai area.However,geophysical evidence does not appear to support the'mantle plume'or'delamination'model for the North China Craton destruction.The crustal structure of the Bohai Sea revealed'a relatively normal crust and obviously thinned mantle lid',local velocity anomalies and instability phenomena in the crust.These features may represent a combined effect of North China-Yangtze collision at an early stage and the remote action of Pacific plate subduction at a late stage. | HAO Tianyao YOU Qingyu LIU Lihua LV Chuanchuan XU Ya LI Zhiwei ZHAO Chunlei ZHENG Yanpeng LIU Chenguang HAN Guozhong | 2013 | Acta Oceanologica Sinica2013，32，12： | 11 |

| 5 | Dandelion-Like Bi_(2)S_(3)/rGO hierarchical microspheres as high-performance anodes for potassium-ion and half/full sodium-ion batteries显示文摘Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) have been considered as attractive alternatives for next-generation battery systems, which have promising application potential due to their earth abundance of potassium and sodium, high capacity and suitable working potential, however, the design and application of bi-functional high-performance anode still remain a great challenge up to date. Bismuth sulfide is suitable as anode owing to its unique laminar structure with relatively large interlayer distance to accommodate larger radius ions, high theoretical capacity and high volumetric capacity etc. In this study, dandelion-like Bi_(2)S_(3)/rGO hierarchical microspheres as anode material for PIBs displayed reversible capacity, and 206.91 mAh·g^(−1) could be remained after 1,200 cycles at a current density of 100 mA·g^(−1). When applied as anode materials for SIBs, 300 mAh·g^(−1) could be retained after 300 cycles at 2 A·g^(−1) and its initial Coulombic efficiency is as high as 97.43%. Even at high current density of 10 A·g^(−1), 120.3 mAh·g^(−1) could be preserved after 3,400 cycles. The Na_(3)V_(2)(PO_(4))_(3)@rGO//Bi_(2)S_(3)/rGO sodium ion full cells were successfully assembled which displays stable performance after 60 cycles at 100 mA·g^(−1). The above results demonstrate that Bi2S3/rGO has application potential as high performance bi-functional anode for PIBs and SIBs. | Xiuping Sun Lu Wang Chuanchuan Li Debao Wang Iqbal Sikandar Ruxia Man Fang Tian Yitai Qian Liqiang Xu | 2021 | Nano Research2021，14，12： | 2 |
| 6 | Pseudo pilot-aided OFDM system with high spectral efficiency for high performance coaxial transmission显示文摘High performance network over coax(HINOC) has become next-generation broadcasting network(NGB) industry standard of China, as well as International Telecommunication Union(ITU) telecommunication standard, which adopts orthogonal frequency division multiplexing(OFDM) technique and high order modulation formats. As is known, in OFDM system, phase noise destroys the orthogonality of the subcarriers and degrades the performance of the system especially when the data are transmitted in high order modulation formats. In this paper, we propose a high spectral efficiency OFDM system utilizing a novel and almost blind phase noise compensation method mainly used for high performance coaxial transmission. In our system, some subcarriers, which remain to transmit unknown useful data in lower order modulation formats, are selected as pseudo pilots instead of pilots to suppress phase noise effectively and high spectral efficiency can be achieved with the aid of puncturing mechanisms. Simulation results show that the proposed pseudo pilot-aided OFDM system can achieve the performance of the pilot-aided counterpart yet acquiring higher spectral efficiency. | Yue LIU Chuanchuan YANG Hongbin LI | 2017 | Science China(Information Sciences)2017，60，6： | 2 |
| 7 | Global warming accelerates the upfreezing of permafrost in arid middle Tianshan Mountains显示文摘Upfreezing is an important geomorphic process in the periglacial environment.It is a product of cold climate and thus an important part of the cryospheric processes.Based on the long-term positioning observations in the source area of the Urumqi River,this article represents an in-depth discussion of the characteristics of sorted circles and upfreezing mechanisms in the Tianshan Mountains.In the source area of the Urumqi River,the intensity of upfreezing is the highest within the top 25 cm near the surface,while targets with a diameter of 3 cm are least affected by upfreezing.There is no distinct difference between the centre with fine grains and the margin with coarse debris within the same sorted circle in terms of the intensity of upfreezing.The correlation analysis demonstrates that temperature plays an important role in upfreezing and the development of sorted circles.A long-time positioning observation of sorted circles reveals that periglacial landforms are sensitive to regional climate change and respond quickly to the temperature increase of the recent two decades.Enhanced upfreezing was found to be due to increased soil moisture content. | LI ChuanChuan CHEN YiXin NIE ZhenYu CUI ZhiJiu LIU GengNian | 2013 | Chinese Science Bulletin2013，58，31： | 2 |
| 8 | Enzymatically-degradable hydrogel coatings on titanium for bacterial infection inhibition and enhanced soft tissue compatibility via a self-adaptive strategy显示文摘Ideal percutaneous titanium implants request both antibacterial ability and soft tissue compatibility.ZnO structure constructed on titanium has been widely proved to be helpful to combat pathogen contamination,but the biosafety of ZnO is always questioned.How to maintain the remarkable antibacterial ability of ZnO and efficiently reduce the corresponding toxicity is still challenging.Herein,a hybrid hydrogel coating was constructed on the fabricated ZnO structure of titanium,and the coating was proved to be enzymatically-degradable when bacteria exist.Then the antibacterial activity of ZnO was presented.When under the normal condition(no bacteria),the hydrogel coating was stable and tightly adhered to titanium.The toxicity of ZnO was reduced,and the viability of fibroblasts was largely improved.More importantly,the hydrogel coating provided a good buffer zone for cell ingrowth and soft tissue integration.The curbed Zn ion release was also proved to be useful to regulate fibroblast responses such as the expression of CTGF and COL-I.These results were also validated by in vivo studies.Therefore,this study proposed a valid self-adaptive strategy for ZnO improvement.Under different conditions,the sample could present different functions,and both the antibacterial ability and soft tissue compatibility were finely preserved. | Jin Leng Ye He Zhang Yuan Bailong Tao Ke Li Chuanchuan Lin Kun Xu Maowen Chen Liangliang Dai Xuemin Li Tony Jun Huang Kaiyong Cai | 2021 | Bioactive Materials2021，6，12： | 2 |
| 9 | A flexible BiFeO_(3)-based ferroelectric tunnel junction memristor for neuromorphic computing显示文摘Ferroelectric tunnel junctions(FTJs)as the artificial synaptic devices have been considered promising for constructing brain-inspired neuromorphic computing systems.However,the memristive synapses based on the flexible FTJs have been rarely studied.Here,we report a flexible FTJ memristor grown on a mica substrate,which consists of an ultrathin ferroelectric barrier of BiFeO_(3),a semiconducting layer of ZnO,and an electrode of SrRuO_(3).The obtained flexible FTJ memristor exhibits stable voltage-tuned multistates,and the resistive switchings are robust after 10^(3) bending cycles.The capability of the FTJ as a flexible synaptic device is demonstrated by the functionality of the spike-timing-dependent plasticity with bending,and the accurate conductance manipulation with small nonlinearity(-0.24)and low cycle-to-cycle variation(1.77%)is also realized.Especially,artificial neural network simulations based on experimental device behaviors reveal that the high recognition accuracies up to 92.8%and 86.2%are obtained for handwritten digits and images,respectively,which are close to the performances for ideal memristors.This work highlights the potential applications of FTJ as flexible electronics for data storage and processing. | Haoyang Sun Zhen Luo Chuanchuan Liu Chao Ma Zijian Wang Yuewei Yin Xiaoguang Li | 2022 | Journal of Materiomics2022，8，1： | 2 |
| 10 | Slow light in tapered slot photonic crystal waveguide显示文摘A slotted single-mode photonic crystal waveguide with a linear tapered slot is presented to realize slow light,whose dispersion curve is shifted by changing the slot width.When the slot width is reduced,the band curve shifts in the tapered structure,and the group velocity of light approach zero at the cut-off frequency.Therefore,different frequency components of the guided light are slowed down even localized along the propagation direction inside a tapered slot photonic crystal waveguide.Furthermore,this structure can confine slow light-wave in a narrow slot waveguide,which may effectively enhance the interaction between slow light and the low-index wave-guiding materials filled in the slot.In addition,this tapered slot structure can be used to compensate group velocity dispersion of slow light by modifying the structure,thus opening the opportunity for ultra-wide bandwidth slow light. | WU Jun LI YanPing YANG ChuanChuan PENG Chao WANG ZiYu | 2009 | Chinese Science Bulletin2009，54，20： | 2 |

| 14 | Environmental evolution of Gongwang Mountains during Holocene in northeastern Yunnan,China显示文摘This paper presents the study on two continuous glacio-lacustrine sedimentary deposits, Laotanfang (3 597 m) and Shibantang (3 689 m) located on the southern and northern sides of Hulifang peak in Yunan, China. Environmental change indexes are constructed for each deposit, based on grain size, geochemical and pollen analysis, environmental magnetic susceptibility, and 14C dating. The study of climatic environmental change since the Holocene epoch in this region shows that the climate fluctuated at different stages during the early Holocene, that is, the climate was cool and wet during 8.4-7.7 ka, cold and wet during 7.7-6.5 ka, cold and dry during 6.5-4.7 ka, cool and wet during 4.7-2.1 ka, warm and wet during 2.1-1.0 ka, and warmer and wet since 1 ka. These findings reflect the overlapping influences of the southwest and southeast monsoons in different times during the Holocene in the north part of southwestern China are in accord with other Holocene climate change models in this part of China. | Wei ZHANG Chuanchuan LI Zhijiu CUI Jinliang FENG | 2008 | Global Geology2008，11，3： | 0 |
| 15 | Moderated crevice corrosion susceptibility of Ti6Al4V implant material due to albumin-corrosion interaction显示文摘Localized corrosion of metallic biomaterials is a concerning problem for implant applications.In the present work,the interaction between localized corrosion of Ti6Al4V implant material and adsorption of bovine serum albumin(BSA)was investigated by electrochemical tests,surface morphological and compositional analysis.The artificial crevice was set up on the Ti6Al4V surface to simulate the crevice corrosion of metallic implants.The results show that the BSA adsorption is regulated by the heterogeneous metallic ion release resulted from the crevice corrosion.The negatively charged BSA prefers to aggregate at the interior of artificial crevice due to electrostatic interaction with the concentrated metallic cations in the crevice.In return,the non-uniform BSA adsorption can decrease the crevice corrosion susceptibility of the Ti6Al4V implant material,even though the presence of BSA accelerates the dissolution of passive films.For the Ti6Al4V alloys with artificial crevice,stable localized corrosion occurs after 96 h of immersion in the PBS free of BSA while no stable localized corrosion can be determined in the presence of 4%BSA.It is deduced that the presence of BSA can reduce the surface potential discrepancy between the crevice interior and the crevice exterior.The disclosed mechanism of albumin-corrosion interaction is vital to the localized corrosion control of metallic implants in clinical use. | Jing Wu Meng Li Chuanchuan Lin Pengfei Gao Rui Zhang Xuan Li Jixi Zhang Kaiyong Cai | 2022 | Journal of Materials Science & Technology2022，，14： | 0 |
| 16 | Human Capital Development and Its Influence on FDI Withdrawal:An Empirical Analysis显示文摘This paper examines the causal effect of human capital expansion on the exit of foreignowned firms using the difference-in-differences method together with a quasi-natural experiment involving the expansion of higher education in China in 1999.The expansion of human capital reduces the probability of the exit of foreign-owned firms significantly This conclusion remains robust under a series of tests,including changing the sample range,adjusting the identification method,and considering the trade liberalization.Analysis of the mechanism indicates that human capital expansion reduces the exit probability of foreign-owned firms by stimulating innovation,improving production efficiency,and optimizing the quality of input and output goods.Industries with higher asset specificity are also more likely to restrain the exit of foreign-owned firms through human capital expansion.Overall,the findings of this study provide a good insight into the exit behavior of FDI in China from the perspective of human capital. | Chuanchuan Li Lei Li Haodan Tang Yanyan Zheng Fangming Gong | 2023 | China & World Economy2023，31，5： | 0 |
| 17 | Source enumeration method by combining diagonal loading and constructing second-order statistics显示文摘A source enumeration method based on diagonal loading of eigenvalues and constructing second-order statistics is proposed,for the case that the antenna array observed signals are overlapped with spatial colored noise,and the number of antennas compared with the number of snapshots meet the requirement of general asymptotic regime.Firstly,the sample covariance matrix of the observed signals is obtained,the eigenvalues of the sample covariance matrix can be acquired by eigenvalue decomposition,and the eigenvalues are diagonally loaded,and a new formula for calculating the diagonal loading is presented.Based on the diagonal loaded eigenvalues,the difference values are calculated for the adjacent eigenvalues after diagonal loading,and the statistical variance of the difference values is calculated.On this basis,the second-order statistics of the difference values are constructed,and when the second-order statistics are minimized,the corresponding number of sources is estimated.The proposed method has wide applicability,which is suitable for both general asymptotic regime and classical asymptotic system,and is suitable for both white Gaussian noise environment and colored noise environment.The method makes up for the lack of source enumeration methods in the case of general asymptotic system and colored noise. | Wang Chuanchuan Zeng Yonghu Wang Liandong Li Zhipeng | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，1： | 0 |
| 18 | Theoretical Logic and Empirical Facts of Consumption Structure Upgrade and Domestic Value Chain Circulation under the New Development Pattern显示文摘Under the new development pattern,this paper explores the characteristic tendencies and intergenerational changes of consumption structure upgrade(CSU)as well as the theoretical logic and empirical paradigm affecting the domestic value chain circulation.This paper constructs a region-industry decomposition framework for domestic value chain circulation based on backward demand to explore the impact of CSU on domestic value chain circulation.The results show that:first,CSU can optimize the structure of domestic value chain circulation and strengthen inter-regional value chain linkage;second,CSU promotes domestic value chain circulation through innovation drive,resource optimization and industrial coupling;finally,the domestic value chain circulation effect caused by CSU may be constrained by market segmentation,and accelerating regional economic integration across a country can help build up the main position of domestic value chain. | Bin Liu Chuanchuan Li Qiujing Li | 2022 | China Finance and Economic Review2022，11，3： | 0 |
| 19 | Double crosslinked biomimetic composite hydrogels containing topographical cues and WAY-316606 induce neural tissue regeneration and functional recovery after spinal cord injury显示文摘Spinal cord injury(SCI)is an overwhelming and incurable disabling condition,for which increasing forms of multifunctional biomaterials are being tested,but with limited progression.The promising material should be able to fill SCI-induced cavities and direct the growth of new neurons,with effective drug loading to improve the local micro-organism environment and promote neural tissue regeneration.In this study,a double crosslinked biomimetic composite hydrogel comprised of acellularized spinal cord matrix(ASCM)and gelatin-acrylated-β-cyclodextrin-polyethene glycol diacrylate(designated G-CD-PEGDA)hydrogel,loaded with WAY-316606 to activate canonical Wnt/β-catenin signaling,and reinforced by a bundle of three-dimensionally printed aligned polycaprolactone(PCL)microfibers,was constructed.The G-CD-PEGDA component endowed the composite hydrogel with a dynamic structure with a self-healing capability which enabled cell migration,while the ASCM component promoted neural cell affinity and proliferation.The diffusion of WAY-316606 could recruit endogenous neural stem cells and improve neuronal differentiation.The aligned PCL microfibers guided neurite elongation in the longitudinal direction.Animal behavior studies further showed that the composite hydrogel could significantly recover the motor function of rats after SCI.This study provides a proficient approach to produce a multifunctional system with desirable physiological,chemical,and topographical cues for treating patients with SCI. | Xingchang Zhao Xianzhe Lu Kai Li Shiqiang Song Zhaohui Luo Chuanchuan Zheng Chengliang Yang Xiumei Wang Liqiang Wang Yujin Tang Chong Wang Jia Liu | 2023 | Bioactive Materials2023，，6： | 0 |
| 20 | Sulfur-vacancy-tunable interlayer magnetic coupling in centimeter-scale M0S2 bilayer显示文摘Endowing bilayer transition-metal dichalcogenides(TMDs)with tunable magnetism is significant to investigate the coupling of multiple electron degrees of freedom(DOFs).However,effectively inducing and tuning the magnetic interaction of bilayer TMDs are still challenges.Herein,we report a strategy to tune the interlayer exchange interaction of centimeter-scale MoS2 bilayer with substitutional doping of Co ion,by introducing sulfur vacancy(V_(s))to modulate the interlayer electronic coupling.This strategy could transform the interlayer exchange interaction from antiferromagnetism(AFM)to ferromagnetism(FM),as revealed by the magnetic measurements.Experimental characterizations and theoretical calculations indicate that the enhanced magnetization is mainly because the hybridization of Co 3d band and Vs-induced impurity band alters the forms of interlayer orbital hybridizations between the partial Co atoms in upper and lower layers,and also enhances the intralayer FM.Our work paves the way for tuning the interlayer exchange interaction with defects and could be extended to other two-dimensional(2D)magnetic materials. | Hengli Duan Guinan Li Hao Tan Chao Wang Qian Li Chuanchuan Liu Yuewei Yin Xiaoguang Li Zeming Qi Wensheng Yan | 2022 | Nano Research2022，15，2： | 0 |
