| 1 | Assessing the numbers of SNPs needed to establish molecular IDs and characterize the genetic diversityof soybean cultivars derived from Tokachi nagaha显示文摘The development of a core set of SNP molecular markers that could be widely used in soybean genetic research would greatly facilitate research into the genetic diversity of soybean.We conducted an analysis of Tokachi nagaha and 137 of its descendant soybean cultivars using 4044 SNP markers with the goal of determining the appropriate number of single-nucleotide polymorphisms(SNPs)needed to construct unambiguous molecular IDs and characterize genetic diversity based on a genetic distance matrix correlation method.When the number of SNPs was held constant,the number of accession pairs that could be distinguished increased as the polymorphism informative content(PIC)value of the SNPs increased.A core panel of 20 selected SNPs from 11 linkage groups with a mean PIC value of 0.3703 and a range of 0.3640–0.3749 was able to identify almost all of the accession pairs in our study[9445 pairs(99.92%)].The eight accession pairs that could not be identified with this core SNP set all originated from the same province and some of them had the same parental cultivars.The molecular IDs of the 138 accessions were constructed using the core 20 SNPs.It is known that both the number of SNPs and PIC values should be considered when SNPs are selected for use in the analysis of genetic diversity.In this study,when the PIC value was 0.3460,the correlation coefficient between the genetic distance matrices associated with a panel of 200 SNPs and the total population was>0.800,indicating satisfactory correlation.Our high-accuracy,high-resolution core SNP panel for germplasm fingerprinting and our findings about assessing genetic diversity will likely markedly improve the management and utilization efficiency of soybean germplasm resources. | Zhangxiong Liu Jun Li Xuhong Fan Nang Myint Phyu Sin Htwe Shuming Wang Wen Huang Jiyu Yang Lili Xing Lijun Chen Yinghui Li Rongxia Guan Ruzhen Chang Dechun Wang Lijuan Qiu | 2017 | The Crop Journal2017，5，4： | 10 |
| 2 | Evaluation of the mold-filling ability of alloy melt in squeeze casting显示文摘The mold-filling ability of alloy melt in squeeze casting process was evaluated by means of the maximum length of Archimedes spiral line. A theoretical evaluating model to predict the maximum filling length was built based on the flowing theory of the incompressible viscous fluid. It was proved by experiments and calculations that the mold-filling pressure and velocity are prominent influencing factors on the mold-filling ability of alloy melt. The mold-filling ability increases with the increase of the mold-filling pressure and the decrease of the proper mold-filling velocity. Moreover, the pouring temperature relatively has less effect on the mold-filling ability under the experimental conditions. The maximum deviation of theoretical calculating values with experimental results is less than 15%. The model can quantitatively estimate the effect of every factor on the mold-filling ability. | Haiying Zhang Shuming Xing Qinghua Zhang Jianbo Tan Wen Liu | 2006 | Journal of University of Science and Technology Beijing2006，13，1： | 7 |
| 3 | Analog Optical Computing for Artificial Intelligence显示文摘The rapid development of artificial intelligence(AI)facilitates various applications from all areas but also poses great challenges in its hardware implementation in terms of speed and energy because of the explosive growth of data.Optical computing provides a distinctive perspective to address this bottleneck by harnessing the unique properties of photons including broad bandwidth,low latency,and high energy efficiency.In this review,we introduce the latest developments of optical computing for different AI models,including feedforward neural networks,reservoir computing,and spiking neural networks(SNNs).Recent progress in integrated photonic devices,combined with the rise of AI,provides a great opportunity for the renaissance of optical computing in practical applications.This effort requires multidisciplinary efforts from a broad community.This review provides an overview of the state-of-the-art accomplishments in recent years,discusses the availability of current technologies,and points out various remaining challenges in different aspects to push the frontier.We anticipate that the era of large-scale integrated photonics processors will soon arrive for practical AI applications in the form of hybrid optoelectronic frameworks. | Jiamin Wu Xing Lin Yuchen Guo Junwei Liu Lu Fang Shuming Jiao Qionghai Dai | 2022 | Engineering2022，8，3： | 4 |
| 4 | Haplotype-resolved genome of diploid ginger (Zingiber officinale) and its unique gingerol biosynthetic pathway显示文摘Ginger(Zingiber officinale),the type species of Zingiberaceae,is one of the most widespread medicinal plants and spices.Here,we report a high-quality,chromosome-scale reference genome of ginger‘Zhugen’,a traditionally cultivated ginger in Southwest China used as a fresh vegetable,assembled from PacBio long reads,Illumina short reads,and high-throughput chromosome conformation capture(Hi-C)reads.The ginger genome was phased into two haplotypes,haplotype 1(1.53 Gb with a contig N50 of 4.68 M)and haplotype 0(1.51 Gb with a contig N50 of 5.28 M).Homologous ginger chromosomes maintained excellent gene pair collinearity.In 17,226 pairs of allelic genes,11.9%exhibited differential expression between alleles.Based on the results of ginger genome sequencing,transcriptome analysis,and metabolomic analysis,we proposed a backbone biosynthetic pathway of gingerol analogs,which consists of 12 enzymatic gene families,PAL,C4H,4CL,CST,C3’H,C3OMT,CCOMT,CSE,PKS,AOR,DHN,and DHT.These analyses also identified the likely transcription factor networks that regulate the synthesis of gingerol analogs.Overall,this study serves as an excellent resource for further research on ginger biology and breeding,lays a foundation for a better understanding of ginger evolution,and presents an intact biosynthetic pathway for species-specific gingerol biosynthesis. | Hong-Lei Li Lin Wu Zhaoming Dong Yusong Jiang Sanjie Jiang Haitao Xing Qiang Li Guocheng Liu Shuming Tian Zhangyan Wu Bin Wu Zhexin Li Ping Zhao Yan Zhang Jianmin Tang Jiabao Xu Ke Huang Xia Liu Wenlin Zhang Qinhong Liao Yun Ren Xinzheng Huang Qingzhi Li Chengyong Li Yi Wang Baskaran Xavier-Ravi Honghai Li Yang Liu Tao Wan Qinhu Liu Yong Zou Jianbo Jian Qingyou Xia Yiqing Liu | 2021 | Horticulture Research2021，8，1： | 2 |
| 5 | Effect of lanthanum addition on microstructure and hardness of brass alloys produced by rheological squeeze casting显示文摘The effect of La addition(0-0.30 wt%)on the microstructure and hardness of rheological squeeze casting brass alloys was experimentally investigated.The rheological squeeze casting process is improved by controlling the wall surface crystals and melt flow rate to realise the preparation of semi-solid melt with flow,and a brass alloy workpiece with La is produced.The microstructure and properties of the brass alloy samples were investigated using metallography,scanning electron microscopy,energy-dispersive X-ray spectroscopy,X-ray diffraction and hardness testing.The results indicate that the hardness of the rheological squeeze casting brass alloy is increased by 20.4%from 108 to 130 HBW with an increase in the La content from 0 to 0.30 wt%.The micro structural analysis results show that La significantly refines the primary a-phase grains,and the main mechanism is the constitutional undercooling and heterogeneous nucleation caused by the La enrichment in the front of the solid-liquid interface.The squeeze pressure promotes undercooling,which improves the nucleation rate and affects the solute diffusion and nucleus growth.The dual effects of these two aspects aggravate the grain refinement process,consequently increasing the number of grain boundaries and improving the hardness of the brass alloy. | Wenjing Gao Shuming Xing Ying Wang | 2022 | Journal of Rare Earths2022，40，12： | 2 |
| 6 | Design of process parameters for direct squeeze casting显示文摘On the basis of the analysis of solidification interval and temperature distribution of components manufactured by the squeeze casting method,formulas for calculating the solidification interval and compaction pressure were deduced according to the principal request that the compaction pressure should be equal to or greater than the plastic deformation resistance of the forming component when solidification ended.The solidification interval was proven to be associated with many factors,such as weight of the component,specific heat of the alloy,latent heat,pouring temperature,component temperature at the end of solidification and heat-transfer coefficients.The compaction pressure was related to the strain rate,deformation temperature,and dimension of the de- forming component.The solidification interval and compaction pressure calculated by the formulas deduced in this article were adopted in the production of 45 steel bidirectional chapiter valves,and components with excellent performance were manufactured. | Milan Zhang Shuming Xing Liming Xiao Peiwei Bao Wen Liu Qiao Xin | 2008 | Journal of University of Science and Technology Beijing2008，15，3： | 1 |
| 7 | Particle motion behavior during gasiication of foam carrier in lost foam-squeeze casting of 20%TiC/ZG270-500 composites显示文摘The particle motion behavior affects the distribution of particles in the metal matrix and finally determines the mechanical properties of the particle reinforced metal-matrix composites. To obtain a uniform distribution of TiC particles and excellent strengthening effect in 20%TiC/ZG270-500 composites fabricated by lost foam-squeeze casting(LFSC), the particle motion behavior in the gas gap and the conditions of the particles getting into the molten steel were investigated. The results show that the airflow velocity(v1) and TiC particle motion velocity(uP) change little with the pouring temperature(TP), increase with an increase in metal filling velocity(vP), ratios of cross sections of in-gate/orifice(AP/A0) and orifice/mould cavity(A0/A1), but the increase trend of u P is more intense. The airflow pressure(P1) changes little with TP and A0/A1, but increases with the increasing of vP and AP/A0. Besides, there is a critical velocity(+|3yLGcosθ/ρpdp|1/2) for the particles getting into the molten steel. The higher the particle motion velocity, the easier the particles get into the molten steel and the more uniform the distribution of the particles in the steel matrix. When TP = 1,873 K, vP = 30 mm·s-1, AP/A0 =10 and A0/A1 = 0.02 in this study, the biggest TiC particle motion velocity(20.59 m·s-1) can be gained, and the steel matrix with the most uniformly distributed TiC particles and fine grains are obtained. | Bin Shibo Xing Shuming Guo Lijun Bao Peiwei | 2013 | China Foundry2013，10，6： | 1 |

| 9 | Rheologic behaviors of A356 aluminum alloy billet produced by semisolid continuous casting process显示文摘The experiments for rheologic behaviors of semisolid continuous casting billets of A356 alloy in semisolid state had been carried out with a multifunctional rheometer. The results show that the deformation rate increases with loading time, the maximum strain reaches to 120% (which is one time larger than that of traditional mold casting billet) and the strain can be rapidly eliminated to 10% after unloading. Moreover, there is a critic stress for billet deformation even in semisolid state, which is named as critic shear stress. This stress increases with the decreasing of heating time. The theologic behaviors can be expressed by five elements mechanical model (H2- [N1|H2]-[N2|S]) and can be modified with the increasing of heating time. | Shuming Xing Lizhong ZHANG Yunhui DU Daben ZENG Jinlin TANG | 2004 | China Foundry2004，1，1： | 1 |

| 11 | Effect of Process Factors on Microstructure of Semisolid Continuous Casting Billets显示文摘Semisolid continuous casting (SSCC) is a new technology to produce billets for semisolid metal forming (SSMF). The effect of process factors, such as pouring temperature, stirring rate, preheating temperature and thermal conductivity of stirring chamber, on the microstructure of SSCC billets was studied by means of the factorial experimental method. The results show that the microstructure of SSCC billets can be controlled by the above-mentioned four process factors. In order to obtain fine and rounded granular grains in an SSCC billet, the pouring temperature, preheating temperature and stirring rate should be kept in a moderate range, and the thermal conductivity of stirring chamber should be high. The regression equations with the process factors connecting the microstructure was also set up based on experimental data. | Shuming Xing, Qijie Zhai, Hanqi Hu ( Department of Mechanical Engineering, Tsinghua University, Beijing 100084, China School of Material Science and Engineering, Shanghai University, Shanghai 200072, China Material Science and Engineering School, Univer | 2000 | International Journal of Minerals,Metallurgy and Materials2000，14，4： | 1 |
| 12 | Energy Dissipation and Apparent Viscosity of Semi-solid Metal during Rheological Processes PartⅠ: Energy Dissipation显示文摘The energy dissipation caused by the viscous force has great effects on the flow property of semi-solid metal during rheological processes such as slurry preparing, delivering and cavity filling. Experimental results in this paper indicate that the viscous friction between semi-solid metal and pipe wall, the collisions among the solid particles, and the liquid flow around particles are the three main types of energy dissipation. On the basis of the hydromechanics, the energy dissipation calculation model is built. It is demonstrated that the micro-structural parameters such as effective solid fraction, particle size and shape, and flow parameters such as the mean velocity, the fluctuant velocity of particles and the relative velocity between the fluid and solid phase, affect the energy dissipation of semi-solid metal. | Wen LIU Shuming XING Peiwei BAO Milan ZHANG Liming XIAO | 2007 | Journal of Materials Science & Technology2007，23，3： | 1 |

| 14 | A New Analytical Model for the Flow Stress of Twin-roll Casting Magnesium Sheet at Elevated Temperatures显示文摘To evaluate the flow stress of the twin-roll casting magnesium sheet in high temperature forming processes,a new analytical model was proposed by analyzing stress-strain curves measured under various temperatures and strain rates.The model can be parameterized to reflect the volume fraction of semi-sold grain and sold grains undergoing twinning.By applying the new model,the result showed that the simulated stress-strain curves fit the experiment data very well.Such curve fitting can be employed for any magnesium sheet when the deformation conditions are known.Microstructure evolution indicated that it affected the stress-strain curves directly.The mechanisms of dynamic recrystallization(DRX) depended on the operating deformation mechanisms,which changed with temperatures.And the volume fraction and grain size of DRX changed with the Zener-Hollomon parameter and temperatures. | Zhimin Liu,Shuming Xing ,Peiwei Bao,Nan Li,Shuqing Yao and Milan Zhang School of Mechanical,Electronic and Control Engineering,Beijing Jiaotong University,Beijing 100044,China | 2010 | Journal of Materials Science & Technology2010，26，5： | 0 |
