| 1 | Blood-letting punctures at twelve Jing-Well points of the hand can treat cerebral ischemia in a similar manner to mannitol显示文摘A rat model of middle cerebral artery permanent occlusion was established using the modified Longa method.Successfully established model animals were treated by blood-letting puncture at twelve Jing-Well points of the hand,and/or by injecting mannitol into the caudal vein twice daily.Brain tissue was collected at 24,48 and 72 hours after modeling,and blood was collected through the retinal vein before Evans blue was injected,approximately 1 hour prior to harvesting of brain tissue.Results showed that Evans blue leakage into brain tissue and serum nitric oxide synthase activity were significantly increased in model rats.Treatment with blood-letting punctures at twelve Jing-Well points of the hand and/or injection of mannitol into the caudal vein reduced the amount of Evans blue leakage into the brain tissue and serum nitric oxide synthase activity to varying degrees.There was no significant difference between single treatment and combined treatment.Experimental findings indicate that blood-letting punctures at twelve Jing-Well points of the hand can decrease blood-brain barrier permeability and serum nitric oxide synthase activity in rats following middle cerebral artery occlusion,and its effect is similar to that of mannitol injection alone and Jing-Well points plus mannitol injection. | Xuan Lu Zelin Chen Yi Guo Liang Gao Liyuan Jiang Zhongzheng Li Jianqiao Fang | 2013 | Neural Regeneration Research2013，8，6： | 14 |
| 2 | A Novel Hybrid Data Clustering Algorithm Based on Artificial Bee Colony Algorithm and K-Means显示文摘To improve the performance of K-means clustering algorithm, this paper presents a new hybrid approach of Enhanced artificial bee colony algorithm and Kmeans(EABCK). In EABCK, the original artificial bee colony algorithm(called ABC) is enhanced by a new mutation operation and guided by the global best solution(called EABC). Then, the best solution is updated by Kmeans in each iteration for data clustering. In the experiments, a set of benchmark functions was used to evaluate the performance of EABC with other comparative ABC variants. To evaluate the performance of EABCK on data clustering, eleven benchmark datasets were utilized. The experimental results show that EABC and EABCK outperform other comparative ABC variants and data clustering algorithms, respectively. | TRAN Dang Cong WU Zhijian WANG Zelin DENG Changshou | 2015 | Chinese Journal of Electronics2015，24，4： | 14 |
| 3 | Effects of bloodletting puncture at Jing-Well points in distal ends of finger and toe on survival rate and brain edema in cerebral ischemic rats显示文摘OBJECTIVE:To observe the effects of bloodletting puncture at Jing-Well points in the distal ends of the finger and toe on survival rate,survival time,and brain edema in rats with cerebral ischemia.METHODS:Fifty-four male Sprague-Dawley rats were randomly divided into five groups:normal,sham operation,model,bloodletting puncture at Jing-Well points in distal ends of finger and toe,and puncture without bloodletting at these points.Middle cerebral artery occlusion models were established according to Longa's method.The brains were taken 48 h after the model was established.Brain water content,brain density,brain coefficient,survival rate,and survival time in each group were measured.RESULTS:After bloodletting puncture,the survival time of the rats was prolonged,their brain water content and brain coefficient were reduced,and brain density was increased.CONCLUSION:Bloodletting puncture at Jing-Well points in the distal ends of the finger and toe can improve function in ischemic brain edema. | Liang Gao Zelin Chen Lixin Tian Zhongzheng Li Yi Guo | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 13 |

| 7 | Application of artificial neural networks in global climate change and ecological research:An overview显示文摘Fields that employ artificial neural networks(ANNs)have developed and expanded continuously in recent years with the ongoing development of computer technology and artificial intelligence.ANN has been adopted widely and put into practice by research-ers in light of increasing concerns over ecological issues such as global warming,frequent El Nio-Southern Oscillation(ENSO)events,and atmospheric circulation anomalies.Limitations exist and there is a potential risk for misuse in that ANN model pa-rameters require typically higher overall sensitivity,and the chosen network structure is generally more dependent upon individ-ual experience.ANNs,however,are relatively accurate when used for short-term predictions;despite global climate change re-search favoring the effects of interactions as the basis of study and the preference for long-term experimental research.ANNs remain a better choice than many traditional methods when dealing with nonlinear problems,and possesses great potential for the study of global climate change and ecological issues.ANNs can resolve problems that other methods cannot.This is especially true for situations in which measurements are difficult to conduct or when only incomplete data are available.It is anticipated that ANNs will be widely adopted and then further developed for global climate change and ecological research. | LIU ZeLin PENG ChangHui XIANG WenHua TIAN DaLun DENG XiangWen ZHAO MeiFang | 2010 | Chinese Science Bulletin2010，55，34： | 9 |
| 8 | Multi-scale image segmentation of coal piles on a belt based on the Hessian matrix显示文摘Segmenting images of coal piles on a belt is an unsolved problem in coal-based machine vision research,though it is an essential step for estimating size distribution and classifying coal.In this investigation,a new algorithm for segmenting images of coal piles on a belt is proposed.A multi-scale linear filter,constructed of a Hessian matrix and Gaussian function,forms the core of this algorithm and obtains an edge intensity image to form good seed regions for a watershed segmentation.Manual segmentation is used to define ground truth segmentation images to quantify the errors of the proposed method.Tests indicate that 12.76%of the visible regions are under- or over-segmented,and that this algorithm is feasible and effective in practical applications. | Zelin Zhang JianguoYang Xiaolan Su Lihua Ding Yuling Wang | 2013 | Particuology2013，11，5： | 9 |

| 10 | Estimation of coal particle size distribution by image segmentation显示文摘Several industrial coal processes are largely determined by the distribution of particle sizes in their feed.Currently these parameters are measured by manual sampling,which is time consuming and cannot provide real time feedback for automatic control purposes.In this paper,an approach using image segmentation on images of overlapped coal particles is described.The estimation of the particle size distribution by number is also described.The particle overlap problem was solved using image enhancement algorithms that converted those image parts representing material in lower layers to black.Exponential high-pass filter(EHPF) algorithms were used to remove the texture from particles on the surface.Finally,the edges of the surface particles were identified by morphological edge detection.These algorithms are described in detail as is the method of extracting the coal particle size.Tests indicate that using more coal images gives a higher accuracy estimate.The positive absolute error of 50 random tests was consistently less than 2.5% and the errors were reduced as the size of the fraction increased. | Zhang Zelin Yang Jianguo Ding Lihua Zhao Yuemin | 2012 | International Journal of Mining Science and Technology2012，22，5： | 7 |
| 11 | Top-emitting thermally activated delayed fluorescence organic light-emitting devices with weak light-matter coupling显示文摘Resonance interaction between a molecular transition and a confined electromagnetic field can lead to weak or strong light-matter coupling.Considering the substantial exciton–phonon coupling in thermally activated delayed fluorescence(TADF)materials,it is thus interesting to explore whether weak light-matter coupling can be used to redistribute optical density of states and to change the rate of radiative decay.Here,we demonstrate that the emission distribution of TADF emitters can be reshaped and narrowed in a top-emitting organic light-emitting device(OLED)with a weakly coupled microcavity.The Purcell effect of weak microcavity is found to be different for TADF emitters with different molecular orientations.We demonstrate that radiative rates of the TADF emitters with vertical orientation can be substantial increased in weakly coupled organic microcavity.These observations can enhance external quantum efficiencies,reduce efficiency roll-off,and improve color-purities of TADF OLEDs,especially for emitters without highly horizontal orientation. | Chunxiu Zang Shihao Liu Mengxin Xu Ruifang Wang Chen Cao Zelin Zhu Jiaming Zhang Hui Wang Letian Zhang Wenfa Xie Chun-Sing Lee | 2021 | Light(Science & Applications)2021，10，7： | 7 |

| 14 | An analytic study on the deflection of subway tunnel due to adjacent excavation of foundation pit显示文摘Predicting and estimating the response of subway tunnel to adjacent excavation of foundation pit is a research focus in the field of underground engineering.Based on the principle of two-stage method and incremental method, an analytic approach is suggested in this paper to solve this problem in an accurate and rapid way,and the upheavals of tunnel due to adjacent excavation are solved by analytic method. Besides, the presented method is used in the practical engineering case of Shenzhen Metro Line 11 and verified by numerical simulation and in situ measurement. Finally, a parametric analysis is performed to investigate the influence of different factors on tunnel's deflection. Some useful conclusions have been drawn from the research as below: The deflection results of tunnel obtained from analytic method are nearly consistent with the results getting from numerical analysis and measured data, which verified the accuracy and rationality of presented method. The excavation size has a significant impact on both the displacement values and influenced range of tunnel. However, the relative distance only impacts the displacement values of tunnel, but not the influenced range of tunnel. It may provide certain reference to analyze the deflection of subway tunnel influenced by adjacent excavation. | Zelin Zhou Shougen Chen Peng Tu Haisheng Zhang | 2015 | Journal of Modern Transportation2015，23，4： | 6 |
| 15 | Advances in environmental behaviors and effects of dissolved organic matter in aquatic ecosystems显示文摘Dissolved organic matter(DOM) is a group of compounds that have complex chemical structures and multiple interactions with their surrounding materials. More than one trillion tons of DOM are stocked in the world's aquatic ecosystems. DOM is a very important part of aquatic ecosystem productivity and plays a crucial role in global carbon cycling. DOM has rich environmental behaviors and effects such as influencing the bioavailability of contaminants, serving as an important inducer of reactive oxygen species(ROS), and protecting aquatic organisms from the harm of dangerous ultraviolet radiation. There have been many systematic studies on the composition, structure, and sources of DOM because such studies are much easier to conduct than studies on the environmental behaviors and effects of DOM. Due to many factors, the research systems of DOM's environmental behaviors and effects are still being developed and have become a hotspot of environmental science. This review paper focuses on some critical progress, problems, and trends of DOM's environmental behaviors and effects in aquatic ecosystems, including mutual exchange mechanisms between DOM and particulate organic matter(POM) with influencing factors, photochemical behaviors of DOM especially inducing ROS, binding interactions between DOM and anthropogenic organic contaminants(AOC), interactions between DOM and microorganisms, effects of DOM on pollutants' bioavailability, ecotoxicity, and ecological risks. Hopefully, this paper will contribute to a more systematic understanding of the DOM environmental behaviors and effects and to promoting further relevant studies. | HE Wei BAI ZeLin LI YiLong KONG XiangZhen LIU WenXiu YANG Chen YANG Bin XU FuLiu | 2016 | Science China Earth Sciences2016，59，4： | 6 |
| 16 | Tuning the selectivity of photoreduction of CO2 to syngas over Pd/layered double hydroxide nanosheets under visible light up to 600 nm显示文摘Photocatalytic reduction of CO2 with H2 O to syngas is an effective way for producing high value-added chemical feedstocks such as methanol and light olefins in industry.Nevertheless,the precise control of CO/H2 ratio from photocatalytic CO2 reduction reaction still poses a great challenge for the further application.Herein,we prepared a series of highly efficient heterostructure based on highly dispersed palladium supported on ultrathin Co Al-layered double hydroxide(LDH).In conjunction with a Ru-complex sensitizer,the molar ratios of CO/H2 can be tuned from 1:0.74 to 1:3 under visible-light irradiation(λ>400 nm).More interestingly,the syngas can be obtained under light irradiation atλ>600 nm.Structure characterization and density functional theory calculations revealed that the remarkable catalytic activity can be due to the supported palladium,which improved the charge transfer efficiency.Meanwhile,more H atoms were used to generate H2 on the supported palladium for further tunable CO/H2 ratio.This work demonstrates a new strategy for harnessing abundant solar-energy to produce syngas from a CO2 feedstock. | Xian Wang Zelin Wang Ya Bai Ling Tan Yanqi Xu Xiaojie Hao Jikang Wang Abdul Hanif Mahadi Yufei Zhao Lirong Zheng Yu-Fei Song | 2020 | Journal of Energy Chemistry2020，29，7： | 5 |
| 17 | Quantized Hybrid Precoding Design for Millimeter-Wave Large-Scale MIMO Systems显示文摘Millimeter wave(mmWave) and large-scale multiple input multiple output(MIMO) are two emerging technologies in fifth-generation wireless communication systems. The power consumption and hardware cost of radio frequency(RF) chains increase exponentially with the bit resolution of analog-to-digital converters(ADCs) and digital-to-analog converters(DACs). One promising solution is to employ few RF chains with low-bit ADCs and DACs. In this paper, we consider mmWave large-scale MIMO systems with low bits DACs and ADCs. Leveraging on the Bussgang theorem and the additive quantization noise model(AQNM), a closed-form expression of the achievable rate is derived to show the effect of the ADCs? and DACs? resolution. Moreover, an orthogonal matching pursuit(OMP) based hybrid precoding algorithm is proposed to increase the achievable rate. Our results show that the impact of DACs is more pronounced than the impact of ADCs. Furthermore, 5-bit ADCs and DACs are sufficient at the transceiver to operate without a significant performance loss. | Zelin Lu Yunliang Zhang Jiayi Zhang | 2019 | China Communications2019，16，4： | 4 |
| 18 | A motion compensation method for wide-swath synthetic aperture sonar显示文摘When the swath of Synthetic Aperture Sonar(SAS) is considerably wide, the spacevariant effect of motion errors becomes remarkable. This space-variant effect makes Displace Phase Center Algorithm(DPCA) invalid. To solve the problem, a motion compensation method for wide-swath SAS is proposed. This method uses mixed modulated Lagrange explicit time delay estimation(MMLETDE) to estimate the time delay between two successive pings of the raw echo data, and then motion errors are fitted by linear regression. After that, the raw echo data can be precisely compensated point by point with the estimations of motion errors.Simulation results show that the proposed method can obtain better motion estimation results than DPCA. The resolution measured on the reconstructed image processed by the proposed method is very close to the theoretical resolution. The lake trail results of high frequency and low frequency SAS data show that the quality of the images of the terrain area and small targets is significantly improved. | ZHANG Pengfei JIANG Zelin LIU Wei LIU jiyuan ZHANG Chunhua | 2016 | Chinese Journal of Acoustics2016，35，3： | 4 |
| 19 | On-chip chalcogenide microresonators with low-threshold parametric oscillation显示文摘Chalcogenide glass (ChG) is an attractive material for highly efficient nonlinear photonics,which can cover an ultrabroadband wavelength window from the near-visible to the footprint infrared region. However,it remains a challenge to implement highly-efficient and low-threshold optical parametric processes in chip-scale ChG devices due to thermal and light-induced instabilities as well as a high-loss factor in ChG films. Here,we develop a systematic fabrication process for high-performance photonic-chip-integrated ChG devices,by which planarintegrated ChG microresonators with an intrinsic quality (Q) factor above 1 million are demonstrated. In particular,an in situ light-induced annealing method is introduced to overcome the longstanding instability underlying ChG film. In high-Q ChG microresonators,optical parametric oscillations with threshold power as low as 5.4 mW are demonstrated for the first time,to our best knowledge. Our results would contribute to efforts of making efficient and low-threshold optical microcombs not only in the near-infrared as presented but more promisingly in the midinfrared range. | BIN ZHANG PINGYANG ZENG ZELIN YANG DI XIA JIAXIN ZHAO YAODONG SUN YUFEI HUANG JINGCUI SONG JINGSHUN PAN HUANJIE CHENG DUKYONG CHOI ZHAOHUI LI | 2021 | Photonics Research2021，9，7： | 4 |
