| 1 | Modified Cuckoo Search Algorithm to Solve Economic Power Dispatch Optimization Problems显示文摘A modified cuckoo search(CS) algorithm is proposed to solve economic dispatch(ED) problems that have nonconvex, non-continuous or non-linear solution spaces considering valve-point effects, prohibited operating zones, transmission losses and ramp rate limits. Comparing with the traditional cuckoo search algorithm, we propose a self-adaptive step size and some neighbor-study strategies to enhance search performance.Moreover, an improved lambda iteration strategy is used to generate new solutions. To show the superiority of the proposed algorithm over several classic algorithms, four systems with different benchmarks are tested. The results show its efficiency to solve economic dispatch problems, especially for large-scale systems. | Jian Zhao Shixin Liu Mengchu Zhou Xiwang Guo Liang Qi | 2018 | IEEE/CAA Journal of Automatica Sinica2018,5,4: | 14 |

| 3 | Automatic segmentation of foveal avascular zone based on adaptive watershed algorithm in retinal optical coherence tomography angiography images显示文摘The size and shape of the foveal avascular zone(FAZ)have a strong positive correlation with several vision-threatening ret inovascular diseases.The identification,segmentation and analysis of FAZ are of great significance to clinical diagnosis and treatment.We presented an adaptive watershed algorithm to automatically extract F AZ from retinal optical coherence tomography angiography(OCTA)images.For the traditional watershed algorithm,'over-segmentation'is the most common problem.FAZ is often incorrectly divided into multiple regions by redundant'dams'.This paper analyzed the relationship between the'dams'length and the maximum inscribed circle radius of FAZ,and proposed an adaptive watershed algorithm to solve the problem of'over-segmentation'.Here,132 healthy retinal images and 50 diabetic retinopathy(DR)images were used to verify the accuracy and stability of the algorithm.Three ophthal-mologists were invited to make quan titative and qualitative evaluations on the segmentation results of this algorithm.The quantitative evaluation results show that the correlation coffi-cients between the automatic and manual segmentation results are 0.945(in healthy subjects)and 0.927(in DR patients),respectively.For qualitative evaluation,the percentages of'perfect segmentation'(score of 3)and'good segmentation'(score of 2)are 99.4%(in healthy subjects)and 98.7%(in DR patients),respectively.This work promotes the application of watershed algorithm in FAZ segmentation,making it a useful tool for analyzing and diagnosing eye diseases. | Jian Liu Shixin Yan Nan Lu Dongni Yang Chunhui Fan Hongyu Lv Shuanglian Wang in Zhu Yuqian Zhao Yi Wang Zhenhe Ma Yao Yu | 2022 | Journal of Innovative Optical Health Sciences2022,15,1: | 3 |
| 4 | Dynamics of Discrete Bubble in Nucleate Pool Boiling on Thin Wires in Microgravity显示文摘A space experiment on bubble behavior and heat transfer in subcooled pool boiling phenomenon has been performedutilizing the temperature-controlled pool boiling (TCPB) device both in normal gravity in the laboratoryand in microgravity aboard the 22^(nd) Chinese recoverable satellite. The fluid is degassed R113 at 0.1 MPa andsubcooled by 26℃ nominally. A thin platinum wire of 60 μm in diameter and 30 mm in length is simultaneouslyused as heater and thermometer. Only the dynamics of the vapor bubbles, particularly the lateral motion and thedeparture of discrete vapor bubbles in nucleate pool boiling are reported and analyzed in the present paper. It'sfound that these distinct behaviors can be explained by the Marangoni convection in the liquid surrounding vaporbubbles. The origin of the Marangoni effect is also discussed. | Shixin WAN,Jianfu ZHAO~* and Gang LIUNational Microgravity Laboratory,Institute of Mechanics,Chinese Academy of Sciences.15 Beisihuan Xilu,Beijing100190,China Professor | 2009 | Journal of Thermal Science2009,18,1: | 3 |
| 5 | Reliability model of organization management chain of South-to-North Water Diversion Project during construction period显示文摘In order to analyze the indispensability of the organization management chain of the South-to-North Water Diversion Project (SNWDP), two basic forms (series connection state and mixed state of both series connection and parallel connection) of the organization management chain can be abstracted. The indispensability of each form has been studied and is described in this paper. Through analysis of the reliability of the two basic forms, reliability models of the organization management chain in the series connection state and the mixed state of both series connection and parallel connection have been set up. | Feng Jingchun Zhou Yang Hong Yuzhen Zhao Shixin Ren Xiaoqiang | 2008 | Water Science and Engineering2008,1,4: | 3 |
| 6 | Dual-Objective Mixed Integer Linear Program and Memetic Algorithm for an Industrial Group Scheduling Problem显示文摘Group scheduling problems have attracted much attention owing to their many practical applications.This work proposes a new bi-objective serial-batch group scheduling problem considering the constraints of sequence-dependent setup time,release time,and due time.It is originated from an important industrial process,i.e.,wire rod and bar rolling process in steel production systems.Two objective functions,i.e.,the number of late jobs and total setup time,are minimized.A mixed integer linear program is established to describe the problem.To obtain its Pareto solutions,we present a memetic algorithm that integrates a population-based nondominated sorting genetic algorithm II and two single-solution-based improvement methods,i.e.,an insertion-based local search and an iterated greedy algorithm.The computational results on extensive industrial data with the scale of a one-week schedule show that the proposed algorithm has great performance in solving the concerned problem and outperforms its peers.Its high accuracy and efficiency imply its great potential to be applied to solve industrial-size group scheduling problems. | Ziyan Zhao Shixin Liu MengChu Zhou Abdullah Abusorrah | 2021 | IEEE/CAA Journal of Automatica Sinica2021,8,6: | 3 |
| 7 | Joint 2D DOA and Doppler frequency estimation for L-shaped array using compressive sensing显示文摘A joint two-dimensional(2D)direction-of-arrival(DOA)and radial Doppler frequency estimation method for the L-shaped array is proposed in this paper based on the compressive sensing(CS)framework.Revised from the conventional CS-based methods where the joint spatial-temporal parameters are characterized in one large scale matrix,three smaller scale matrices with independent azimuth,elevation and Doppler frequency are introduced adopting a separable observation model.Afterwards,the estimation is achieved by L1-norm minimization and the Bayesian CS algorithm.In addition,under the L-shaped array topology,the azimuth and elevation are separated yet coupled to the same radial Doppler frequency.Hence,the pair matching problem is solved with the aid of the radial Doppler frequency.Finally,numerical simulations corroborate the feasibility and validity of the proposed algorithm. | WANG Shixin ZHAO Yuan LAILA Ibrahim XIONG Ying WANG Jun TANG Bin | 2020 | Journal of Systems Engineering and Electronics2020,31,1: | 2 |
| 8 | Research and practice of intelligent coal mine technology systems in China显示文摘This study considered the role of coal as China’s basic energy source and examines the development of the coal industry.We focused on the intelligent development of coal mines,and introduced the“Chinese mode”of intelligent mining in underground coal mines,which uses complete sets of technical equipment to propose classifcation and grading standards.In view of the basic characteristics and technical requirements of intelligent coal mine systems,we established a digital logic model and propose an information entity and knowledge map construction method.This involves an active information push strategy based on a knowledge demand model and an intelligent portfolio modeling and distribution method for collaborative control of coal mines.The top-level architecture of 5G+intelligent coal mine systems combines intelligent applications such as autonomous intelligent mining,human–machine collaborative rapid tunneling,unmanned auxiliary transportation,closed-loop safety control,lean collaborative operation,and intelligent ecology.Progress in intelligent mining technology was described in terms of a dynamic modifed geological model,underground 5G network and positioning technology,intelligent control of the mining height and straightness of the longwall working face,and intelligent mining equipment.The development of intelligent coal mines was analyzed in terms of its imbalances,bottlenecks,and the compatibility of large-scale systems.Implementation ideas for promoting the development of intelligent coal mines were proposed,such as establishing construction standards and technical specifcations,implementing classifcation and grading standards according to mining policy,accelerating key technology research,and building a new management and control model. | Guofa Wang Huaiwei Ren Guorui Zhao Desheng Zhang Zhiguo Wen Lingyu Meng Shixin Gong | 2022 | International Journal of Coal Science & Technology2022,9,2: | 2 |
| 9 | FWENet:a deep convolutional neural network for flood water body extraction based on SAR images显示文摘As one of the most severe natural disasters in the world,floods caused substantial economic losses and casualties every year.Timely and accurate acquisition of flood inundation extent could provide technical support for relevant departments in the field of flood emergency response and disaster relief.Given the accuracy of existing research works extracting flood inundation extent based on Synthetic Aperture Radar(SAR)images and deep learning methods is relatively low,this study utilized Sentinel-1 SAR images as the data source and proposed a novel model named flood water body extraction convolutional neural network(FWENet)for flood information extraction.Then three classical semantic segmentation models(UNet,Deeplab v3 and UNet++)and two traditional water body extraction methods(Otsu global thresholding method and Object-Oriented method)were compared with the FWENet model.Furthermore,this paper analyzed the water body area change situations of Poyang Lake.The main results of this paper were as follows:Compared with other five water body extraction methods,the FWENet model achieved the highest water body extraction accuracy,its F1 score and mean intersection over union(mIoU)were 0.9871 and 0.9808,respectively.This study could guarantee the subsequent research on flood extraction based on SAR images. | Jingming Wang Shixin Wang Futao Wang Yi Zhou Zhenqing Wang Jianwan Ji Yibing Xiong Qing Zhao | 2022 | International Journal of Digital Earth2022,15,1: | 1 |
| 10 | I/P interface modification for stable and efficient perovskite solar cells显示文摘Interface engineering has played an increasingly essential role in the development of perovskite solar cells(PSCs).Herein,we adopted an effective and simple one-step interface passivation method on a FA-based perovskite to fabricate efficient and stable planar PSCs.The surface defects are reduced by the perovskite interface passivation layer incorporated between the hole transport and perovskite absorber layers,and then non-radiative recombination is suppressed while interfacial carrier extraction is enhanced.The passivated planar PSCs demonstrates 20.83%power conversion efficiency(PCE),which is caused by the simultaneous enhancement of the fill factor and open-circuit voltage.In addition,the device also shows great ambient and thermal stability.It retains 94%of its original PCE after 1000 h under ambient air without encapsulation as well as90%of its initial efficiency after 400 h under continuous heating at 65°C with encapsulation.This research provides a strategy for the development of efficient and stable PSCs. | Jie Zhang Shixin Hou Renjie Li Bingbing Chen Fuhua Hou Xinghua Cui Jingjing Liu Qi Wang Pengyang Wang Dekun Zhang Ying Zhao Xiaodan Zhang | 2020 | Journal of Semiconductors2020,41,5: | 1 |

| 12 | Two-phase flow in anode flow field of a small direct methanol fuel cell in different gravities显示文摘An in-situ visualization of two-phase flow inside anode flow bed of a small liquid fed direct methanol fuel cells in normal and reduced gravity has been conducted in a drop tower.The anode flow bed con-sists of 11 parallel straight channels.The length,width and depth of single channel,which had rec-tangular cross section,are 48.0,2.5 and 2.0mm,respectively.The rib width was 2.0mm.The experi-mental results indicated that when the fuel cell orientation is vertical,two-phase flow pattern in anode channels can evolve from bubbly flow in normal gravity into slug flow in microgravity.The size of bub-bles in the reduced gravity is also bigger.In microgravity,the bubbles rising speed in vertical channels is obviously slower than that in normal gravity.When the fuel cell orientation is horizontal,the slug flow in the reduced gravity has almost the same characteristic with that in normal gravity.It implies that the effect of gravity on two-phase flow is small and the bubbles removal is governed by viscous drag.When the gas slugs or gas columns occupy channels,the performance of liquid fed direct methanol fuel cells is failing rapidly.It infers that in long-term microgravity,flow bed and operating condition should be optimized to avoid concentration polarization of fuel cells. | GUO Hang WU Feng YE Fang ZHAO JianFu WAN ShiXin LüCuiPing MA ChongFang | 2009 | Science China(Technological Sciences)2009,52,6: | 1 |
| 13 | Efficient grain refinement of Al alloys induced by in-situ nanoparticles显示文摘Grain refinement of Al and Al alloys during the solidification remains a long-term challenge.Here we report a general strategy for efficient grain refinement through instantaneously in-situ forming abundant nanoparticles with concentrated size distribution.The Al-Zn-Mg-Cu alloy and commercial purity Al are respectively refined by using this proposed strategy and the traditional refinement method(adding AlTi-B alloy into Al melt),and the experimental and numerical results indicate that the TiBnanoparticles instantaneously form in the Al melt during the in-situ refinement process.Compared to the traditional refinement treatment method,the new approach not only can promote the high number density of the nucleation sites and narrow their size distribution,but also tremendously attenuates the agglomeration and settlement of the heterogeneous nucleation sites.It exhibits much better grain refinement ability and inhibits the decline of the grain refinement efficiency.This approach may have broad application prospect not only for the grain refinement of Al and Al alloys,but also for the grain refinement of other alloy systems,e.g.steel,magnesium,copper,and so on. | Hongxiang Jiang Yan Song Lili Zhang Jie He Shixin Li Jiuzhou Zhao | 2022 | Journal of Materials Science & Technology2022,,29: | 1 |

| 15 | Electrospun nanofiber/hydrogel composite materials and their tissue engineering applications显示文摘Electrospun nanofiber/hydrogel composites combine the excellent biochemical properties of hydrogel with the biomimetic nature of electrospun fibers,and have attracted widespread attention in the last few years.Besides,nanofiber/hydrogel composites with tunable mechanical properties can mimic the microstructure of extracellular matrix(ECM)of various tissues and the microenvironment of different cells.These features enable electrospun fiber/hydrogel composites have uniquely advantageous for tissue repair.However,a comprehensive review of electrospun fiber/hydrogel composites as tissue engineering scaffolds is still lacking.Thus,this article systematically reviewed the preparation of electrospun fiber/hydrogel composites and their application in tissue engineering.First,the preparation strategies of electrospun fiber/hydrogel composites are classified and discussed.Second,the application of electrospun fiber/hydrogel-based scaffolds in tissue engineering,involving skin,blood vessel,nerve,bone and other tissue engineering,are summarized.Finally,future research directions for functional electrospun fiber/hydrogel scaffold materials are proposed. | Miaomiao Zhang Shixin Xu Ruoying Wang Yongan Che Cuicui Han Wei Feng Chengwei Wang Wen Zhao | 2023 | Journal of Materials Science & Technology2023,,31: | 0 |
| 16 | Microwave diagnostics of pulsed atmospheric discharge with electrolytic electrode and long-lived luminous formation in its afterglow显示文摘The Gatchina discharge phenomenon holds significant promise as a laboratory model for simulating ball lightning.However,crucial aspects concerning the plasma components of the resulting afterglow remain unresolved.Notably,the measurement of the electron density,a critical parameter,has not been fully achieved thus far.In this study,microwave diagnostics and video recording were employed during a pulsed Gatchina discharge,along with synchronous measurement of discharge current and voltage.Distinct antennas were positioned at different heights to enable separate diagnosis of the discharge and the ensuing long-lived afterglow.The findings revealed that during the active phase of the Gatchina discharge,the plasma density was substantial enough to cause reflection of an electromagnetic wave with a frequency of 20 GHz from this highly conductive object.In the afterglow,the signal experienced only a moderate weakening of 10–20 percent,facilitating the determination of the time dependence of average electron density during the afterglow's passage between the two antennas.These measurements verified the unusually slow plasma decay in the afterglow of the Gatchina discharge,suggesting the potential significance of chemi-ionisation processes involving long-lived(metastable)particles. | Shixin Zhao Xingbao Lyu Aleksandr Astafiev Chengxun Yuan Lin Miao Jingfeng Yao Ying Wang Anatoly Kudryavtsev Aleksandr Chirtsov Gennadii Shabanov Zhongxiang Zhou | 2024 | High Voltage2024,9,1: | 0 |

| 18 | STUDY ON THE PERFORMANCE AND MECHANISM OF ADSORPTING RHENIUM BY USING NEUTRAL PHOSPHOROUS-BASED LEVEXTREL RESIN Ⅱ. CL-P350-KReO_4-HCl System显示文摘In this paper study on the property and mechanism of adsorpting rhenium from aqueous hydrochloric acid by using methyl phosphorous acid dimythyl heptyl ester levextrel resin(CL-P350) is reported.The effects of time,acidity,concentration of rhenium,and temperature on the adsorption of rhenium were investigated. The mechanism of adsorpting rhenium was discussed by chemical analytic and IR method,and dynamic adscrption and elution were studied.Experimental results show that the adsorption equilibration is reached in 4 min,the distribution coefficient(D) of Re(Ⅶ)increases with increase of concentration of HCl and reaches maximum 3.0-4.0moL/L HCl.ReO4^- is taken up by ion association mechanism and can be described by Langmuir equation of the equilibrium state.The thermodynamic parameters in the adsorption process of ReO4^- have been determined to be:ΔH=-29KJ/moL,ΔG=-25KJ/moL and ΔS=-13.5J/moL respectively.The saturation adsorption capacity of rhenium is 19.2mg/g when the solution containing 0.372g/L Re and 3.0mol/L HCl was passed through the resin column.The recovery percentage of rhenium is 98.4% while distilled water was used as an eluent. | HE Huanjie, ZHAO Deqi, ZHAN Shixin, FENG Jianzhong, WANG Zhanhe (Laboratory, Zhongyuan Petroleum School, Puyang 457001, China) | 1993 | Chinese Journal of Reactive Polymers1993,2,2: | 0 |
| 19 | Macrophage LMO7 deficiency facilitates inflammatory injury via metabolic-epigenetic reprogramming显示文摘Inflammatory bowel disease(IBD)is a formidable disease due to its complex pathogenesis.Macrophages,as a major immune cell population in IBD,are crucial for gut homeostasis.However,it is still unveiled how macrophages modulate IBD.Here,we found that LIM domain only 7(LMO7)was downregulated in pro-inflammatory macrophages,and that LMO7 directly degraded 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3(PFKFB3)through K48-mediated ubiquitination in macrophages.As an enzyme that regulates glycolysis,PFKFB3 degradation led to the glycolytic process inhibition in macrophages,which in turn inhibited macrophage activation and ultimately attenuated murine colitis.Moreover,we demonstrated that PFKFB3 was required for histone demethylase Jumonji domaincontaining protein 3(JMJD3)expression,thereby inhibiting the protein level of trimethylation of histone H3 on lysine 27(H3K27me3).Overall,our results indicated the LMO7/PFKFB3/JMJD3 axis is essential for modulating macrophage function and IBD pathogenesis.Targeting LMO7 or macrophage metabolism could potentially be an effective strategy for treating inflammatory diseases. | Shixin Duan Xinyi Lou Shiyi Chen Hongchao Jiang Dongxin Chen Rui Yin Mengkai Li Yuseng Gou Wenjuan Zhao Lei Sun Feng Qian | 2023 | Acta Pharmaceutica Sinica B2023,13,12: | 0 |
