| 1 | Biomimetic Shoulder Complex Based on 3-PSS/S Spherical Parallel Mechanism显示文摘The application of the parallel mechanism is still limited in the humanoid robot fields, and the existing parallel humanoid robot joint has not yet been reflected the characteristics of the parallel mechanism completely, also failed to solve the problem, such as small workspace, effectively. From the structural and functional bionic point of view, a three degrees of freedom(DOFs) spherical parallel mechanism for the shoulder complex of the humanoid robot is presented. According to the structure and kinetic characteristics analysis of the human shoulder complex, 3-PSS/S(P for prismatic pair, S for spherical pair) is chosen as the original configuration for the shouder complex. Using genetic algorithm, the optimization of the 3-PSS/S spherical parallel mechanism is performed, and the orientation workspace of the prototype mechanism is enlarged obviously. Combining the practical structure characteristics of the human shouder complex, an offset output mode, which means the output rod of the mechanism turn to any direction at the point a certain distance from the rotation center of the mechanism, is put forward, which provide possibility for the consistent of the workspace of the mechanism and the actual motion space of the human body shoulder joint. The relationship of the attitude angles between different coordinate system is derived, which establishs the foundation for the motion descriptions under different conditions and control development. The 3-PSS/S spherical parallel mechanism is proposed for the shoulder complex, and the consistence of the workspace of the mechanism and the human shoulder complex is realized by the stuctural parameter optimization and the offset output design. | HOU Yulei HU Xinzhe ZENG Daxing ZHOU Yulin | 2015 | Chinese Journal of Mechanical Engineering2015，28，1： | 22 |
| 2 | Biomonitoring for traditional herbal medicinal products using DNA metabarcoding and single molecule, real-time sequencing显示文摘Global concerns have been paid to the potential hazard of traditional herbal medicinal products(THMPs). Substandard and counterfeit THMPs, including traditional Chinese patent medicine, health foods, dietary supplements, etc. are potential threats to public health. Recent marketplace studies using DNA barcoding have determined that the current quality control methods are not sufficient for ensuring the presence of authentic herbal ingredients and detection of contaminants/adulterants. An efficient biomonitoring method for THMPs is of great needed. Herein, metabarcoding and single-molecule, realtime(SMRT) sequencing were used to detect the multiple ingredients in Jiuwei Qianghuo Wan(JWQHW), a classical herbal prescription widely used in China for the last 800 years. Reference experimental mixtures and commercial JWQHW products from the marketplace were used to confirm the method. Successful SMRT sequencing results recovered 5416 and 4342 circular-consensus sequencing(CCS) reads belonging to the ITS2 and psb A-trn H regions. The results suggest that with the combination of metabarcoding and SMRT sequencing, it is repeatable, reliable, and sensitive enough to detect species in the THMPs, and the error in SMRT sequencing did not affect the ability to identify multiple prescribed species and several adulterants/contaminants. It has the potential for becoming a valuable tool for the biomonitoring of multi-ingredient THMPs. | Tianyi Xin Zhichao Xu Jing Jia Christine Leon Songnian Hu Yulin Lin Subramanyam Ragupathy Jingyuan Song Steven G.Newmaster | 2018 | Acta Pharmaceutica Sinica B2018，8，3： | 22 |
| 3 | Determining "abnormal" levator hiatus distensibility using three-dimensional transperineal ultrasound in Chinese women显示文摘The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). Thisretrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort.Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results werecompared between women with and without significantly objective prolapse (International Continence SocietyPOP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed todetermine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantlyobjective prolapse had significantly higher levator hiatus dimensions than those without (all P 〈 0.001). ROCcurve analyses confirmed that hiatal area (HA) of 19.5 cm2 during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In thisstudy, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ≥ 19.5 cm2 duringValsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility. | Chaoran Dou Qin Li Tao Ying Yulin Yan Xia Wang Bing Hu | 2018 | Frontiers of Medicine2018，12，5： | 21 |
| 4 | Dynamic compression characteristics of layered rock mass of significant strength changes in adjacent layers显示文摘Layered rock mass of significant strength changes for adjacent layers is frequently observed in underground excavation,and dynamic loading is a prevalent scenario generated during excavation.In order to improve the driving efficiency and reduce engineering accidents,dynamic compression characteristics of this kind of rock mass should be understood.The dynamic properties of a layered composite rock mass are investigated through a series of rock tests and numerical simulations.The rock mass is artificially made of various proportions of sand,cement and water to control the distinct strength variations at various composite layers separated by parallel bedding planes.All rock specimens are prefabricated in a specially designed mould and then cut into 50 mm in diameter and 50 mm in height for split Hopkinson pressure bar(SHPB)dynamic compression testing.The test results reveal that increasing strain rate causes the increases of peak strength,σ_p,and the corresponding failure strain,ε_p,while the dynamic elastic modulus,E_d,remains almost unchanged.Interestingly,under the same strain rates,Ed of the composite rock specimen is found to decline first and then increase as the dip angle of bedding plane increases.The obtained rock failure patterns due to various dip angles lead to failure modes that could be classified into four categories from our dynamic tests.Also,a series of counterpart numerical simulations has been undertaken,showing that dynamic responses are in good agreement with those obtained from the SHPB tests.The numerical analysis enables us to Iook into the dynamic characteristics of the composite rock mass subjected to a broader range of strain rates and dip angles than these being tested. | Sen Wen Chunshun Zhang Yulin Chang Ping Hu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，2： | 13 |
| 5 | The calcium-dependent protein kinase ZmCDPK7 functions in heat-stress tolerance in maize显示文摘Global warming poses a serious threat to crops.Calcium-dependent protein kinases(CDPKs)/CPKs play vital roles in plant stress responses,but their exact roles in plant thermotolerance remains elusive.Here,we explored the roles of heat-induced ZmCDPK7 in thermotolerance in maize.ZmCDPK7-overexpressing maize plants displayed higher thermotolerance,photosynthetic rates,and antioxidant enzyme activity but lower H2 O2 and malondialdehyde(MDA)contents than wild-type plants under heat stress.ZmCDPK7-knockdown plants displayed the opposite patterns.ZmCDPK7 is attached to the plasma membrane but can translocate to the cytosol under heat stress.ZmCDPK7 interacts with the small heat shock protein sHSP17.4,phosphorylates sHSP17.4 at Ser-44 and the respiratory burst oxidase homolog RBOHB at Ser-99,and up regulates their expression.Site-directed mutagenesis of sHSP17.4 to generate a Ser-44-Ala substitution reduced ZmCDPK7’s enhancement of catalase activity but enhanced ZmCDPK7’s suppression of MDA accumulation in heat-stressed maize protoplasts.sHSP17.4,ZmCDPK7,and RBOHB were less strongly upregulated in response to heat stress in the abscisic acid-deficient mutant vp5 versus the wild type.Pretreatment with an RBOH inhibitor suppressed sHSP17.4 and ZmCDPK7 expression.Therefore,abscisic acid-induced ZmCDPK7 functions both upstream and downstream of RBOH and participates in thermotolerance in maize by mediating the phosphorylation of sHSP17.4,which might be essential for its chaperone function. | Yulong Zhao Hanwei Du Yankai Wang Huali Wang Shaoyu Yang Chaohai Li Ning Chen Hao Yang Yihao Zhang Yulin Zhu Luyao Yang Xiuli Hu | 2021 | Journal of Integrative Plant Biology2021，63，3： | 6 |
| 6 | miR-27b-3p/MARCH7 regulates invasion and metastasis of endometrial cancer cells through Snail-mediated pathway显示文摘Ubiquitin E3 ligase membrane-associated RING-CH-type finger 7(MARCH7),also known as axotrophin,was originally identified in mouse embryonic stem cells.MARCH7 is involved in T-cell proliferation,neuronal development,and the immune system.However,its role in endometrial cancer(EC)remains unclear.This study aimed to investigate the role of MARCH7 in EC.Quantitative polymerase chain reaction,immunohistochemistry,and western blot analysis were used to examine the expression of MARCH7,E-cadherin,Snail,and Vimentin in EC cell lines or clinical specimens.The role of MARCH7 in maintaining EC cell malignant phenotype was determined by transwell assay and using xenograft tumor model.Dual-luciferase reporter gene assay was performed to determine whether MARCH7 is an authentic target of miR-27b-3p.Our data showed that the expression level of MARCH7 in EC tissues was higher than that in normal endometrium tissues.The level of MARCH7 was positively associated with that of Snail and Vimentin,clinical stage,and histological grade,while negatively associated with that of E-cadherin.Knockdown of MARCH7 inhibited the invasion and metastasis of EC cells in vitro and in vivo.The opposite effect was observed after overexpressing MARCH7.MARCH7 promoted invasion and metastasis of EC cells via the Snail-mediated pathway.Furthermore,MARCH7 was demonstrated to be an authentic target of miR-27b-3p,and miR-27b-3p decreased the stimulus effect induced by MARCH7.These data indicate that MARCH7 may be an oncogenic factor and a therapeutic target for EC.miR-27b-3p/MARCH7 may also regulate EC cell invasion and metastasis via the Snail-mediated pathway. | Ling Liu Jianguo Hu Tinghe Yu Shuang You Yulin Zhang Lina Hu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，5： | 6 |
| 7 | TMEM43-S358L mutation enhances NF-κBTGFp signal cascade in arrhythmogenic right ventricular dysplasia/cardiomyopathy显示文摘Arrhythmogenic right ventricular dysplasia/cardiomyopathy(ARVD/C)is a genetic cardiac muscle disease that accounts for approximately 30%sudden cardiac death in young adults.The Ser358Leu mutation of transmembrane protein 43(TMEM43)was commonly identified in the patients of highly lethal and fully penetrant ARVD subtype,ARVD5.Here,we generated TMEM43 S358L mouse to explore the underlying mechanism.This mouse strain showed the classic patholo.gies of ARVD patients,including structural abnormalities and cardiac fibrofatty.TMEM43 S358L mutation led to hyper-activated nuclear factor kB(NFkB)activation in heart tissues and primary cardiomy.ocyte cells.Importantly,this hyper activation of NF-κB directly drove the expression of pro-fibrotic gene,transforming growth factor beta(TGFβ),and enhanced downstream signal,indicating that TMEM43 S358L mutation up-regulates NF-κB-TGFβ signal cascade during ARVD cardiac fibrosis.Our study partially reveals the regulatory mechanism of ARVD development. | Guoxing Zheng Changying Jiang Yulin Li Dandan Yang Youcai Ma Bing Zhang Xuan Li Pei Zhang Xiaoyu Hu Xueqiang Zhao Jie Du Xin Lin | 2019 | Protein & Cell2019，10，2： | 5 |
| 8 | Phosphate recovery with granular acid-activated neutralized red mud:Fixed-bed column performance and breakthrough curve modelling显示文摘Granular acid-activated neutralized red mud(AaN-RM)has been successfully prepared with good chemical stability and physical strength.However,its potential for industrial application remains unknown.Therefore,the performance of granular AaN-RM for phosphate recovery in a fixed-bed column was investigated.The results demonstrated that the phosphate adsorption performance of granular AaN-RM in a fixed-bed column was affected by various operational parameters,such as the bed depth,flow rate,initial solution pH and initial phosphate concentration.With the optimal empty-bed contact time(EBCT)of 24.27 min,the number of processed bed volumes and the phosphate adsorption capacity reached 496.95 and 84.80 mg/g,respectively.Then,the saturated fixed-bed column could be effectively regenerated with a0.5 mol/L HCl solution.The desorption efficiency remained as high as 83.45%with a low weight loss of 3.57%in the fifth regeneration cycle.In addition,breakthrough curve modelling showed that a 5-9-1 feed-forward artificial neural network(ANN)could be effectively applied for the optimization of the fixed-bed adsorption system;the coefficient of determination(R^2)and the root mean square error(RMSE)evaluated on the validation-testing data were 0.9987 and 0.0183,respectively.Therefore,granular AaN-RM fixed-bed adsorption exhibits promising potential for phosphate removal and recovery from polluted water. | Andong Hu Guoping Ren Jiangang Che Yulin Guo Jie Ye Shungui Zhou | 2020 | Journal of Environmental Sciences2020，32，4： | 4 |

| 10 | Insulating materials for realising carbon neutrality:Opportunities,remaining issues and challenges显示文摘The 2050 carbon-neutral vision spawns a novel energy structure revolution,and the construction of the future energy structure is based on equipment innovation.Insulating material,as the core of electrical power equipment and electrified transportation asset,faces unprecedented challenges and opportunities.The goal of carbon neutral and the urgent need for innovation in electric power equipment and electrification assets are first discussed.The engineering challenges constrained by the insulation system in future electric power equipment/devices and electrified transportation assets are investigated.Insulating materials,including intelligent insulating material,high thermal conductivity insulating material,high energy storage density insulating material,extreme environment resistant insulating material,and environmental-friendly insulating material,are cat-egorised with their scientific issues,opportunities and challenges under the goal of carbon neutrality being discussed.In the context of carbon neutrality,not only improves the understanding of the insulation problems from a macro level,that is,electrical power equipment and electrified transportation asset,but also offers opportunities,remaining issues and challenges from the insulating material level.It is hoped that this paper en-visions the challenges regarding design and reliability of insulations in electrical equipment and electric vehicles in the context of policies towards carbon neutrality rules.The authors also hope that this paper can be helpful in future development and research of novel insulating materials,which promote the realisation of the carbon-neutral vision. | Chuanyang Li Yang Yang Guoqiang Xu Yao Zhou Mengshuo Jia Shaolong Zhong Yu Gao Chanyeop Park Qiang Liu Yalin Wang Shakeel Akram Xiaoliang Zeng Yi Li Fangwei Liang Bin Cui Junpeng Fang Lingling Tang Yulin Zeng Xingtao Hu Jiachen Gao Giovanni Mazzanti Jinliang He Jianxiao Wang Davide Fabiani Gilbert Teyssedre Yang Cao Feipeng Wang Yunlong Zi | 2022 | High Voltage2022，7，4： | 4 |
| 11 | ZbAGL11, a class D MADS-box transcription factor of Zanthoxylum bungeanum, is involved in sporophytic apomixis显示文摘Apomixis is a reproductive model that bypasses sexual reproduction,so it does not require the combination of paternal and maternal gametes but instead results in the production of offspring directly from maternal tissues.This reproductive mode results in the same genetic material in the mother and the offspring and has signi fi cant applications in agricultural breeding.Molecular and cytological methods were used to identify the reproductive type of Zanthoxylum bungeanum(ZB).Fluorescence detection of the ampli fi ed products of 12 pairs of polymorphic SSR primers showed consistent fl uorescence signals for mother and offspring,indicating that no trait separation occurred during reproduction.In addition,the cytological observation results showed differentiation of ZB embryos(2n)from nucellar cells(2n)to form inde fi nite embryonic primordia and then form adventitious embryos(2n),indicating that the apomictic type of ZB is sporophytic apomixis.The MADS-box transcription factor ZbAGLll was highly expressed during the critical period of nucellar embryo development in ZB.Unpollinated ZbAGLll-OE Arabidopsis produced fertile offspring and exhibited an apomictic phenotype.The overexpression of ZbAGL11 increased the callus induction rate of ZB tissue.In addition,the results of the yeast two-hybrid experiment showed that ZbAGL11 could interact with the ZbCYP450 and ZbCAD11 proteins.Our results demonstrate that ZbAGL11 can cause developmental disorders of Arabidopsis fl ower organs and result in apomixis-like phenotypes. | Xitong Fei Qianqian Shi Yichen Qi Shujie Wang Yu Lei Haichao Hu Yulin Liu Tuxi Yang Anzhi Wei | 2021 | Horticulture Research2021，8，1： | 3 |
| 12 | The LTR of endogenous retrovirus ev21 retains promoter activity and exhibits tissue specific transcription in chicken显示文摘Endogenous viruses integrate into the host genome and influence the expression of neighboring genes through their long terminal repeats (LTRs). In this study, we analyzed the promoter, enhancer and transcriptional activities of the chicken endogenous retrovirus ev21 LTR. The LTR was cloned into pGL3-basic and pGL3-promoter luciferase vectors in forward and reverse orientation separately. The luciferase activities were detected respectively in chicken embryonic fibroblast cell, human embryonic kidney cell line, human lung carcinoma cell line, Chinese hamster ovary cell line, and murine melanoma cell line. Relative luciferase activity analysis indicated that the ev21 LTR retained bi-directional promoter activity but no detectable enhancer activity in these cells. The constructs containing the LTR and F1 region show stronger promoter activity than the constructs containing only LTR. The transcriptional pattern of ev21 LTR varied in tissues of late feathering White Leghorn chicken at post-hatch day one. Skin exhibits the highest expression in the tissues examed. Collectively, our results indicate that the ev21 LTR exhibits tissue-type specific expression in White Leghorn chicken, and it also have regulatory potential. | LU XiaoQing HAN JinRun LIU XiaoFang LIN TongHui LI YuLin HU XiaoXiang LI Ning | 2009 | Chinese Science Bulletin2009，54，24： | 3 |
| 13 | Structures of SdrD from Staphylococcus aureus reveal the molecular mechanism of how the cell surface receptors recognize their ligands显示文摘Staphylococcus aureus is the most important Gram-positive colonizer of human skin and nasal passage,causing high morbidity and mortality.SD-repeat containing protein D(SdrD),an MSCRAMM(Microbial Surface Components Recognizing Adhesive Matrix Molecules)family surface protein,plays an important role in S.aureus adhesion and pathogenesis,while its binding target and molecular mechanism remain largely unknown.Here we solved the crystal structures of SdrD N2-N3 domain and N2-N3-B1 domain.Through structural analysis and comparisons,we characterized the ligand binding site of SdrD,and proposed a featured sequence motif of its potential ligands.In addition,the structures revealed for the first time the interactions between B1 domain and N2-N3 domain among B domain-containing MSCRAMMs.Our results may help in understanding the roles SdrD plays in S.aureus adhesion and shed light on the development of novel antibiotics. | Xiao Wang Jingpeng Ge Bao Liu Yulin Hu Maojun Yang | 2013 | Protein & Cell2013，4，4： | 3 |
| 14 | Modes of genetic adaptations underlying functional innovations in the rumen显示文摘The rumen is the hallmark organ of ruminants and hosts a diverse ecosystem of microorganisms that facilitates efficient digestion of plant fibers.We analyzed 897 transcriptomes from three Cetartiodactyla lineages:ruminants,camels and cetaceans,as well as data from ruminant comparative genomics and functional assays to explore the genetic basis of rumen functional innovations.We identified genes with relatively high expression in the rumen,of which many appeared to be recruited from other tissues.These genes show functional enrichment in ketone body metabolism,regulation of microbial community,and epithelium absorption,which are the most prominent biological processes involved in rumen innovations.Several modes of genetic change underlying rumen functional innovations were uncovered,including coding mutations,genes newly evolved,and changes of regulatory elements.We validated that the key ketogenesis rate-limiting gene(HMGCS2)with five ruminant-specific mutations was under positive selection and exhibits higher synthesis activity than those of other mammals.Two newly evolved genes(LYZ1 and DEFB1)are resistant to Gram-positive bacteria and thereby may regulate microbial community equilibrium.Furthermore,we confirmed that the changes of regulatory elements accounted for the majority of rumen gene recruitment.These results greatly improve our understanding of rumen evolution and organ evo-devo in general. | Xiangyu Pan Yudong Cai Zongjun Li Xianqing Chen Rasmus Heller Nini Wang Yu Wang Chen Zhao Yong Wang Han Xu Songhai Li Ming Li Cunyuan Li Shengwei Hu Hui Li Kun Wang Lei Chen Bin Wei Zhuqing Zheng Weiwei Fu Yue Yang Tingting Zhang Zhuoting Hou Yueyang Yan Xiaoyang Lv Wei Sun Xinyu Li Shisheng Huang Lixiang Liu Shengyong Mao Wenqing Liu Jinlian Hua Zhipeng Li Guojie Zhang Yulin Chen Xihong Wang Qiang Qiu Brian PDalrymple Wen Wang Yu Jiang | 2021 | Science China(Life Sciences)2021，64，1： | 3 |

| 16 | Designing HVDC GIS/GIL spacer to suppress charge accumulation显示文摘To suppress the charge accumulation on the spacer surface in direct current(DC)gas insulated transmission line(GIL)is an important and emergent issue for the development of a clean,safe and economic smart grid.A design method of the DC spacer is proposed,and a spacer prototype is prepared and evaluated both by simulation and type test.The DC withstand voltage test and polarity reversal test are performed using the new DC spacer compared with a commercialised 220 kVAC spacer.The simulation results indicate that the surface electric field and surface charge of the DC spacer are lower than those of the alternating current(AC)spacer under DC voltage.The test results verify that the surface flashover voltage of this DC spacer is higher than that of the AC spacer.The potential feasibility of the spacer design for HVDC is discussed.It is hoped that the content of this paper can bring new ideas in the development of HVDC gas insulated equipment. | Zuodong Liang Chuanjie Lin Fangwei Liang Weijian Zhuang Yujia Xu Lingling Tang Yulin Zeng Jun Hu Bo Zhang Chuanyang Li Jinliang He | 2022 | High Voltage2022，7，4： | 2 |
| 17 | Synthesis of LiFePO_4 using FeSO_4·7H_2O byproduct from TiO_2 production as raw material显示文摘As the byproduct of TiO2 industrial production, impure FeSO4·7H2O was used for the synthesis of LiFePO4. With the purified solution of FeSO4·7H2O, FePO4·xH2O was prepared by a normal titration method and a controlled crystallization method, respectively. Then LiFePO4 materials were synthesized by calcining the mixture of FePO4·xH2O, Li2CO3, and glucose at 700°C for 10 h in flowing Ar. The results indicate that the elimination of FeSO4·7H2O impurities reached over 95%, and using FePO4·xH2O prepared by the controlled crystallization method, the obtained LiFePO4 material has fine and sphere-like particles. The material delivers a higher initial discharge specific capacity of 149 mAh·g-1 at a current density of 0.1C rate (1C=170 mA·g-1); the discharge specific capacity also maintains above 120 mAh·g1 after 100 cycles even at 2C rate. Thus, the employed processing is promising for easy control, low cost of raw material, and high electrochemical performance of the prepared material. | PENG Zhongdong CAO Yanbing ZHOU Yulin HU Guorong | 2009 | Rare Metals2009，28，6： | 2 |
| 18 | MICROSTRUCTURE AND MECHANICAL PROPERTIES OF 8090 Al-Li ALLOY显示文摘The change of mechanical properties of the 8090 Al-Li alloy influenced by aging is attributedto the change of δ′-phase particle size and the precipitation of S′-phase.The δ′-phase mayeasily precipitate and rapidly grow,but the S′-phase can only precipitate with a longer stageof incubation.The precipitation of S′-phase would be promoted by cold working prior to ag-ing.The co-precipitation of δ′- and S′-phase could improve the strength and plastieity of thealloy,for which aging at 190℃.for 20—30 h seems to be optimal.In addition,the precipitatefree zone( PFZ)can form at high angle grain boundary and its width is over 200 nm in peakaging condition.But at sub-grain boundary,the formation of PFZ is difficult. | LIU Yulin ZHANG Yun ZHAO Hong’en HU Zhuangqi SHI Changxu Institute of Metal Research,Academia Sinica,Shentang,China | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，2： | 2 |
