| 1 | Intent Pattern Recognition of Lower-limb Motion Based on Mechanical Sensors显示文摘Based on the regularity nature of lower-limb motion,an intent pattern recognition approach for above-knee prosthesis is proposed in this paper. To remedy the defects of recognizer based on electromyogram(EMG), we develop a pure mechanical sensor architecture for intent pattern recognition of lower-limb motion. The sensor system is composed of an accelerometer, a gyroscope mounted on the prosthetic socket, and two pressure sensors mounted under the sole. To compensate the delay in the control of prosthesis, the signals in the stance phase are used to predict the terrain and speed in the swing phase. Specifically, the intent pattern recognizer utilizes intraclass correlation coefficient(ICC) according to the Cartesian product of walking speed and terrain. Moreover, the sensor data are fused via DempsterShafer's theory. And hidden Markov model(HMM) is used to recognize the realtime motion state with the reference of the prior step. The proposed method can infer the prosthesis user's intent of walking on different terrain, which includes level ground,stair ascent, stair descent, up and down ramp. The experiments demonstrate that the intent pattern recognizer is capable of identifying five typical terrain-modes with the rate of 95.8%. The outcome of this investigation is expected to substantially improve the control performance of powered above-knee prosthesis. | Zuojun Liu Wei Lin Yanli Geng Peng Yang | 2017 | IEEE/CAA Journal of Automatica Sinica2017，4，4： | 15 |
| 2 | Effect of heat treatment on mechanical properties of heavily cold-rolled Fe-6.5wt%Si alloy sheet显示文摘Fe-6.5wt%Si alloy has excellent soft magnetic properties,but it is hard to be cold-rolled due to appearance of ordered phases in this alloy.In this paper we report that ultra thin Fe-6.5wt%Si sheet of 0.05 mm thick was obtained by heavily cold rolling.By means of optical microscope,micro-hardness indenter,instron,SEM and X-ray diffraction,the effect of heat treatment on mechanical properties of this alloy sheet was investigated.The heavily cold-rolled sheet exhibits some extent of ductility.The ultimate tensile strength reaches 1.93 GPa.After heat treatment,micro-hardness is decreased and the ductility is lost,especially at temperature above 650℃ when recrystallization takes place.The reason for decreasing the ductility lies in the ordered DO3 phase transformation. | LIANG YongFeng,YE Feng,LIN JunPin,WANG YanLi,ZHANG LaiQi & CHEN GuoLiang State Key Laboratory for Advanced Metals and Materials,University of Science and Technology Beijing,Beijing 100083,China | 2010 | Science China(Technological Sciences)2010，53，4： | 10 |
| 3 | Determination of both jasmonic acid and methyl jasmonate in plant samples by liquid chromatography tandem mass spectrometry显示文摘An efficient method for the simultaneous extraction and quantification of both jasmonic acid(JA)and methyl jasmonate(MeJA) from a single plant sample was developed.Plant tissues were firstly extracted by using 100%cold methanol,then the Sep-pak C18 solid-phase extraction(SPE)cartridges were adopted for the purification of sample extract,and finally JA and MeJA were determined by the liquid chromatography tandem mass spectrometry(LC-MS-MS)system.It was found that the accuracy was improved by using the extra standard for the estimation and correction of JA and MeJA losses in the extraction and purification process.The detection limits for JA and MeJA were 0.03 and 0.075 ng mL-1,respectively,and the average recovery rate of JA and MeJA was 92.48%and 94.30%.The method was found to be reproducible and selective,yielding well isolated and easily detectable peaks for both JA and MeJA and simplifying the time-consuming extraction and purification.High-performance liquid chromatography(HPLC)system was employed as the control detection method for the LC-MS-MS system.The two systems were compared in their specificity and accuracy. | LIU Xia YANG YanLi LIN WanHuang TONG JianHua HUANG ZhiGang XIAO LangTao | 2010 | Chinese Science Bulletin2010，55，21： | 10 |

| 5 | Simulation of CO_2 variations at Chinese background atmospheric monitoring stations between 2000 and 2009: Applying a CarbonTracker model显示文摘We carried out a downscaling treatment over China using the CarbonTracker numerical model,which was applied using double grid nesting technology(3°×2°over the whole globe,1°×1°over China),simulating and analyzing atmospheric CO2concentrations over 10 recent years(2000–2009).The simulation results agreed very well with observed data from four background atmospheric monitoring stations in China(The periods for which the simulation results and observed values be compared were January2000 to December 2009 for the WLG station and June 2006 to December 2009 for the SDZ,LFS,and LAN stations),giving correlation coefficients of>0.7.The high-resolution simulation data correlated slightly better than the low resolution simulation data with the observed data for three of the regions’atmospheric background stations.Further analysis of the annual,seasonal CO2concentration variations at the background stations showed that the CO2concentration increased each year over the study period,with an average annual increase of more than 5%,and annual increases of more than 7%at the Shangdianzi and Lin’an stations.Seasonal CO2variations were greater at the Longfengshan station than at the Shangdianzi or Lin’an stations.However,the CO2concentrations were higher at the Shangdianzi and Lin’an stations because they are greatly affected by human activities in the Jingjinji and Changjiang Delta economic zones.Spatial distribution in CO2concentrations and fluxes were higher in eastern than in western China. | CHENG YanLi AN XingQin YUN FangHua ZHOU LingXi LIU LiXin FANG ShuangXi XU Lin | 2013 | Chinese Science Bulletin2013，58，32： | 8 |
| 6 | Dynamic recrystallization during hot torsion of Al-4Mg alloy显示文摘Binary Al-4Mg alloy have been deformed by hot torsion at 300-500℃ and strain rates of 0,006-1.587 s-1 to a true strainof 5.5. The specimens were annealed in vacuum for 1.5 h at 500℃ and then water quenched. The study indicates that the dynamicrecrystallization occurs during hot torsion of Al-4Mg alloy in a certain range of Z parameter (Zener-Hollmon Parameter), i.e. 19.3 ≤lnZ ≤ 24.8. Increasing the strain rate at higher deformation temperature or reducing the strain rate at lower deformation temperatureaccelerates the occurrence of dynamic recrystallization in the alloy. | Junpin Lin, Yanli Wang, Zhi Lin, and Guoliang ChenState Key Laboratory of Advanced Metal Materials, University of Science and Technology Beijing, Beijing 100083, China | 2003 | Journal of University of Science and Technology Beijing2003，10，2： | 6 |
| 7 | A topologically substituted boron nitride hybrid aerogel for highly selective CO2 uptake显示文摘A topologically mediated synthesis of porous boron nitride aerogel has been experimentally and theoretically investigated for carbon dioxide (CO2)uptake. Replacement of the carbon atoms in a precursor aerogel of graphene oxide and carbon nanotubes was achieved using an elemental substitution reaction,to obtain a boron and nitrogen framework.The newly prepared BN aerogel possessed a specific surface area of 716.56m^2/g and exhibited an unprecedented twenty- fold increase in CO2uptake over N2,adsorbing 100cc/g at 273K and 80cc/g in ambient conditions,as verified by adsorption isotherms via the multipoint Brunauer-Emmett-Teller (BET)method.Density functional theory calculations were performed to give hints on the mechanism of such high selectivity of CO2 over N2adsorption in BN aerogel,which may be due to the interaction between the intrinsic polar nature of B-N bonds and the high quadrupole moment of CO2 over N2. | R.Govindan Kutty Sivaramapanicker Sreejith Xianghua Kong Haiyong He Hong Wang Junhao Lin Kazu Suenaga Chwee Teck Lim Yanli Zhao Wei Ji Zheng Liu | 2018 | Nano Research2018，11，12： | 5 |
| 8 | Isothermal corrosion Fe_3Si alloy in liquid zinc显示文摘The isothermal corrosion testing, microscopic examination and the performance of Fe3Si alloy as materials of construction for bath hardware in continuous hot-dipping lines were studied. The corrosion of Fe3Si alloy in molten zinc was controlled by at- tacking the grain boundaries preferentially. Aluminum reacted with iron of Fe3Si alloy firstly while the samples were immersed in molten zinc, although aluminum contents in the molten zinc were very low. The phase of reaction product was thought to be Fe2Al5. The corrosion rate of the Fe3Si alloy in molten zinc was determined to be approximately 2.9×10?3 mm/h, therefore the liquid zinc cor- rosion resistance of Fe3Si alloy was very weak. | Wenjun Wang Junping Lin Yanli Wang Guoliang Chen | 2007 | Journal of University of Science and Technology Beijing2007，14，1： | 4 |
| 9 | Mechanism of Residual Stress Reduction in Low Alloy Steel by a Low Frequency Alternating Magnetic Treatment显示文摘Residual stress reduction in low alloy steel by a low frequency alternating magnetic treatment and its mechanism were investigated. Experimental results revealed that average stress reductions of 20%-24% were obtained in the welded samples. Moreover, compared with the zones with lower initial stress levels, more remarkable stress reductions were obtained in the stress concentration zones. The microstructures and magnetic domains were observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Based on the analysis of the microstructure and magnetic domain changes, the mechanism of stress reduction by the magnetic treatment has been concluded: (1) the magneto-plastic deformations mainly due to the more uniform redistribution of dislocations are the fundamental cause of stress relaxation; and (2) surface topography is also proved to affect the magnetic treatment results to some degree by influencing magnetic domains. | Yanli Song Lin Hua | 2012 | Journal of Materials Science & Technology2012，28，9： | 4 |

| 11 | Telomere-to-telomere and gap-free reference genome assembly of the kiwifruit Actinidia chinensis显示文摘Kiwifruit is an economically and nutritionally important fruit crop with extremely high contents of vitamin C.However,the previously released versions of kiwifruit genomes all have a mass of unanchored or missing regions.Here,we report a highly continuous and completely gap-free reference genome of Actinidia chinensis cv.‘Hongyang’,named Hongyang v4.0,which is the first to achieve two de novo haploid-resolved haplotypes,HY4P and HY4A.HY4P and HY4A have a total length of 606.1 and 599.6 Mb,respectively,with almost the entire telomeres and centromeres assembled in each haplotype.In comparison with Hongyang v3.0,the integrity and contiguity of Hongyang v4.0 is markedly improved by filling all unclosed gaps and correcting some misoriented regions,resulting in∼38.6–39.5 Mb extra sequences,which might affect 4263 and 4244 protein-coding genes in HY4P and HY4A,respectively.Furthermore,our gap-free genome assembly provides the first clue for inspecting the structure and function of centromeres.Globally,centromeric regions are characterized by higher-order repeats that mainly consist of a 153-bp conserved centromere-specific monomer(Ach-CEN153)with different copy numbers among chromosomes.Functional enrichment analysis of the genes located within centromeric regions demonstrates that chromosome centromeres may not only play physical roles for linking a pair of sister chromatids,but also have genetic features for participation in the regulation of cell division.The availability of the telomere-to-telomere and gap-free Hongyang v4.0 reference genome lays a solid foundation not only for illustrating genome structure and functional genomics studies but also for facilitating kiwifruit breeding and improvement. | Junyang Yue Qinyao Chen Yingzhen Wang Lei Zhang Chen Ye Xu Wang Shuo Cao Yunzhi Lin Wei Huang He Xian Hongyan Qin Yanli Wang Sijia Zhang Ying Wu Songhu Wang Yi Yue Yongsheng Liu | 2023 | Horticulture Research2023，10，2： | 4 |
| 12 | The Changes in Guilin Paddy Soil Organic Matter and Rice Yield under Long-Term Fertilization显示文摘Rational fertilization is an important measure to increase crop yield and soil fertility. Through analysis,this paper aims to master the change characteristics of soil organic matter and rice yield under different fertilizer treatments,in order to provide an important reference for the sustainable use of soil and effective fertilization. Long-term( 19 years) rice crop rotation experiments in waterloggogenic paddy soil were conducted to investigate the change trend of crop grain yield and soil organic matter with time,reveal the dynamic characteristics and relationship between main fertility factors and crop yields using comparative analysis at three sites with conventional fertilization and non-fertilization in Guilin. The results showed that compared with previous years,the rice yield increased by 53% under the fertilization treatment and degreased by 66% under the control. Over the years,the average soil organic matter( SOM) content under fertilization treatment was 23% higher than under CK treatment. This indicates that chemical fertilizer and organic manure application can increase the rice yield and soil organic matter,and high rice yield can be attributed to the SOM increase. | Qiuliang YU Zheng TANG Zhongfang LI Chunlan CHEN Xiaoxian TANG Yanli LIN | 2016 | Asian Agricultural Research2016，8，3： | 2 |
| 13 | Strain rate sensitivity of tensile properties in high Nb containing TiAl alloys显示文摘The effect of strain rate on the yield strength of high Nb containing TiAl alloy was studied. The results show that the strain rate sensitivity varies with the test temperature, and the yield strength is not sensitive to the strain rate at room temperature but sig- nificantly sensitive to the strain rate at high temperature. An increase of the strain rate or a decrease of the temperature results in an obvious change of fracture mode. It is found that the strain rate sensitivity of this alloy varying with temperature is due to the dislo- cation climb generated at high temperature. | Jianfeng Gao Xiangjun Xu Junpin Lin Xiping Song Yanli Wang Guoliang Chen | 2005 | Journal of University of Science and Technology Beijing2005，12，6： | 2 |
| 14 | Impact of long-term chemical fertilizer and organic amendment to Fusarium root rot of soybean显示文摘Soil suppressiveness to Fusarium root rot of soybean had been observed in a black soil field after a long-term fertilization with nitrogen(N)and phosphorus(P)fertilizer combined with pig manure as organic amendment(NPM),rather than that with only nitrogen and phosphorus fertilizer(NP)or no fertilizer(NF).To determine the microbial role on this suppressiveness,fungal and bacterial community characteristics in NPM,NP and NF treatments were investigated by q PCR and DGGE.Compared with the similar bacterial community characteristics among 3 treatments,fungal community,especially Fusarium population size and community composition in NPM treatment were different with those of NP and NF groups.Based on the isolation and pathogenicity test,pathogenic F.oxysporum,F.graminearum,F.verticillioide and F.lateritium absolutely dominated Fusarium community in NF and NP groups.Nonpathogenic F.avenaceum,F.equiseti,F.culmorum,F.redolens,F.solani and F.tricinctum dominated Fusarium community in NPM group.Isolation rate of pathogenic Fusarium in NPM reduced from 100%to 38%in NF.These results suggested that the dominance of soil non-pathogenic Fusarium population induced by organic amendment might play an important role on suppressing Fusarium root rot in the tested field. | Kaili Wang Xinyu Hu Sai Yang Kaiyan Xing Xin Zhang Lin Zhu Xiaozeng Han Yanli Xu Wei Wei | 2020 | Oil Crop Science2020，5，1： | 2 |
| 15 | Diffusion behavior of Nb element in high Nb containing TiAl Alloys by reactive hot pressing显示文摘Diffusion behavior of Nb in elemental powder metallurgy high Nb containing TiAl alloys was investigated. The results show that Nb element dissolves into the matrix by diffusion. Pore nests are formed in situ after Nb diffusion. With the increase in hot pressing temperature, the diffusion of Nb will be more sufficient, and the microstructure is more homo-geneous. Nb element diffuses completely at 1400°C. Meanwhile, compression deformation and agglomeration phenomena of pores are observed in some pore nests. Hot isostatic pressing (HIP) treatment can only efficiently decrease but not eliminate porosity completely. | WANG Yanhang LIN Junpin HE Yuehui WANG Yanli CHEN Guoliang | 2006 | Rare Metals2006，25，4： | 2 |
| 16 | Determination of optimal dietary selenium levels by full expression of selenoproteins in various tissues of broilers from 1 to 21 d of age显示文摘The current NRC dietary selenium(Se)requirement(0.15 mg/kg)of broilers is primarily based on growth performance data reported in 1986.Our study aimed to determine optimal dietary Se levels of broilers fed a practical corn-soybean meal diet for the full expression of selenoproteins in various tissues.A total of 384 one-d-old male broilers(n=8 replicates/diet)were fed a basal corn-soybean meal diet or the basal diet supplemented with 0.1,0.2,0.3,0.4 or 0.5 mg Se/kg in the form of Na_(2)SeO_(3) for 21 d.Regression analysis was conducted to evaluate the optimal dietary Se levels using broken-line,quadratic or asymptotic models.The activity of glutathione peroxidase(GPX)in the plasma,liver,kidney and pancreas,iodothyronine deiodinase(DIO)in the plasma,liver and pancreas,and thioredoxin reductase(Txnrd)in the liver and pancreas,the mRNA levels of Gpx1,Gpx4,Dio1,selenoprotein(Seleno)h,Selenop and Selenou in the liver,Gpx4,Dio1,Txnrd1,Txnrd2,Selenoh,Selenop and Selenou in the kidney,and Gpx1,Gpx4,Selenoh and Selenou in the pancreas,and the protein levels of GPX4 in the liver and kidney of broilers were influenced(P<0.05)by added Se levels,and increased quadratically(P<0.05)with the increase of added Se levels.The estimates of optimal dietary Se levels were 0.07 to 0.36 mg/kg based on the fitted broken-line,quadratic or asymptotic models(P<0.001)of the aforementioned selenoprotein expression in the plasma,liver and kidney,and 0.09 to 0.46 mg/kg based on the fitted broken-line models(P<0.001)of the aforementioned selenoprotein expression in the pancreas.The results indicate that the optimal dietary Se levels would be 0.36 mg/kg to support the full expression of selenoproteins in the plasma,liver and kidney,and 0.46 mg/kg to support the full expression of selenoproteins in the pancreas of broilers fed a practical corn-soybean meal diet from 1 to 21 d of age. | Xiudong Liao Guoqing Liu Guangming Sun Xiaoming Sun Tao Liu Lin Lu Liyang Zhang Minhong Zhang Yanli Guo Xugang Luo | 2021 | Animal Nutrition2021，，4： | 2 |

| 18 | Construction of on-line supercritical fluid extraction with reverse phase liquid chromatography–tandem mass spectrometry for the determination of capsaicin显示文摘A novel on-line system composed of supercritical fluid extraction(SFE), dilution line and reverse phase liquid chromatography/mass spectrometry(RPLC/MS) was constructed for on-line extraction and reverse phase separation of some fat-soluble components in foods. Three columns including a trap column,concentration column and analytical column were used for trapping the fat-soluble components, on-line enrichment and reverse phase separation, respectively. Capsaicinoids were on-line extracted by a CO_2 supercritical fluid, then concentrated and separated by using the C_(18) columns, finally detected by mass spectrometry(MS). Capsaicin eluted at 10.1 min and limit of detection(LOD, S/N=3) for the standard solution is 0.55pg. The linearity was calculated with a value of coefficient of determination(R^2)≥0.998 in the range of 1.1–8.5 ng. Concentrations of capsaicin in the green, yellow, and red bell peppers were determined to be 60.33 ng/g, 31.79 ng/g, 35.38ng/g, respectively. | Naoki Hamada Yuki Hashi Satoshi Yamaki Yanli Guo Lin Zhang Haifang Li Jin-Ming Lin | 2019 | Chinese Chemical Letters2019，30，1： | 2 |
| 19 | Expression of Pseudorabies Virus gE Core Epitopes in Escherichia coli Strain BL21 and Utilization of Indirect PRV gE-ELISA显示文摘Pseudorabies virus glycoprotein E( PRV gE) has been recognized as a suitable diagnostic antigen for pseudorabies. In order to produce gE antigen in large quantities and at low cost,a gene fragment encoding PRV gE core epitopes was expressed in E. coli BL21 expression system. SDS-PAGE and Western Blotting revealed that the expression product in culture supernatant of E. coli BL21 was a recombinant protein,approximately 51. 8 Kd. At 5 h post-induction,protein concentration assay showed that the expression product amounted to 1. 65 mg /ml,accounting for 24. 17% of total proteins in the culture supernatant. An indirect PRV gE-ELISA was established by using the recombinant expression product as a coating antigen. Cross-reactivity assay showed that this antigen was PRV specific. In addition,the assay was consistently reproducible. Comparison of detection results of 240 serum samples between PRV gE-ELISA and a commercially available PRV diagnostic kit showed that there was no significant difference between these two methods( P > 0. 05). | Guangjun GUO Sufang LU Guanggang QU Feng LI Lin DONG Yanli BI Jinliang WANG Feng WEI Na TANG Chunling ZHANG Zhuang DING Zhiqiang SHEN | 2014 | Agricultural Biotechnology2014，3，4： | 2 |
