| 1 | Application in prestiction friction compensation for angular velocity loop of inertially stabilized platforms显示文摘To overcome the influence of the nonlinear friction on the gimbaled servo-system of an inertial stabilized platforms(ISPs) with DC motor direct-drive, the methods of modeling and compensation of the nonlinear friction are proposed. Firstly, the inapplicability of LuGre model when trying to interpret the backward angular displacement in the prestiction regime is observed experimentally and the reason is deduced theoretically. Then, based on the dynamic model of direct-drive ISPs, a modified LuGre model is proposed to describe the characteristic of the friction in the prestiction regime. Furthermore, the state switch condition of the three friction regimes including presliding, gross sliding and prestiction is presented. Finally, a composite compensation controller including a nonlinear friction observer and a feedforward compensator based on the novel LuGre model is designed to restrain the nonlinear friction and to improve the control precision. Experimental results indicate that compared with those of the conventional proportion–integration–differentiation(PID) control method and the PID plus LuGre model-based friction compensation method, the dwell-time has decreased from 0.2 s to almost 0 s, the position error decreased to 86.7%and the peak-to-peak value of position error decreased to 80% after the novel compensation controller is added. It concludes that the composite compensation controller can greatly improve the control precision of the dynamic sealed ISPs. | Zhang Zhiyong Li Zhiqiang Zhou Qingkun Zhang Lianchao Fan Dapeng | 2014 | Chinese Journal of Aeronautics2014，27，3： | 5 |
| 2 | Analysis of the Arabidopsis Floral Proteome:Detection of over 2000 Proteins and Evidence for Posttranslational Modifications显示文摘The proteome of the Arabidopsis flower has not been extensively studied previously. Here, we report a proteomic analysis of the wild type Arabidopsis flower. Using both two-dimensional electrophoresis/mass spectrometry (2-DGE/MS) and multi-dimensional protein identification technology (MudPIT) approaches, we identified 2 446 proteins. Although a single experiment or analysis uncovered only a subset of the proteins we identified, a combination of multiple experiments and analyses facilitated the detection of a greater number of proteins. When proteins are grouped according to RNA expression levels revealed by microarray experiments, we found that proteins encoded by genes with relatively high levels of expression were detected with greater frequencies. On the other hand, at the level of the individual gene/protein, there was not a good correlation between protein spot intensity and microarray values. We also obtained strong evidence for post-translational modification from 2-DGE and MudPIT data. We detected proteins that are annotated to function in protein synthesis, folding, modification, and degradation, as well as the presence of regulatory proteins such as transcription factors and protein kinases. Finally, sequence and evolutionary analysis of genes for active methyl group metabolisms suggests that these genes are highly conserved. Our results allow the formulation of hypotheses regarding post-translational regulation of proteins in the flower, providing new understanding about Arabidopsis flower development and physiology. | Baomin Feng Lianchao Li Xiaofan Zhou Bruce Stanley Hong Ma | 2009 | Journal of Integrative Plant Biology2009，51，2： | 2 |

| 6 | 前列腺癌靶向基因治疗实验研究的最新进展(英文)显示文摘The absence of effective therapies for castration-resistant prostate cancer(CRPC) establishes the need to develop novel therapeutic modality, such as targeted gene therapy, which is ideal for the treatment of CRPC. But its application has been limited due to lack of favorable gene vector and the reduction of 'bystander effect'. Consequently, scientists all over the world focus their main experimental research on the following four aspects: targeted gene, vector, transfer means and comprehensive therapy. In this paper, we reviewed the latest advances of experimental research on targeted gene therapy for prostate cancer. | Dongliang Pan Lianchao Jin Xianghua Zhang | 2013 | The Chinese-German Journal of Clinical Oncology2013，12，11： | 1 |
| 7 | Prediction of Activities in Fe-Based Ternary Liquid Alloys by Hoch-Arpshofen Model显示文摘Thermodynamic properties for an alloy system play an important role in the materials science and engineering.Therefore,theoretical calculations having the flexibility to deal with complexity are very useful and have scientific meaning.The Hoch-Arpshofen model was deduced from physical principles and is applicable to binary,ternary and larger system using its binary interaction parameters only.Calculations of the activities of Fe-based liquid alloys are calculated using Hoch-Arpshofen model from data on the binary subsystems.Results for the activities for Fe-Au-Ni,Fe-Cr-Ni,Fe-Co-Cr and Fe-Co-Ni systems at required temperature are presented by Hoch-Arpshofen model.The average relative errors of prediction are 7.8%,4.5%,4.9% and 2.7%,respectively.It shows that the calculated results are in good agreement with the experimental data except Fe-Au-Ni system,which exhibits strong interaction between unlike atoms.The model provides a simple,reliable and general method for calculating the activities for Fe-based liquid alloys. | YANGHong—wei LIANChao TAODong—ping | 2012 | Journal of Iron and Steel Research(International)2012，19，6： | 1 |
| 8 | 长期应用国产醋酸亮丙瑞林微球(单月剂型)治疗转移性前列腺癌时对血清睾酮的抑制和潜在刺激作用(英文)显示文摘Objective: We aimed to evaluate the efficiency of serum testosterone suppression as well as the potential for agonistic stimulation of serum testosterone during chronic treatment with monthly(3.75 mg) depot formulation of domestic substitute of leuprorelin acetate microspheres for patients with metastatic prostate cancer. Methods: A total of 23 patients with metastatic prostate cancer were enrolled in the prospective study and received 6 monthly intramuscular depot injections of domestic substitute of leuprorelin acetate microspheres. Their levels and patterns of serum testosterone suppression and the potential for agonistic stimulation of serum testosterone were monitored following injection monthly(3.75 mg) depot formulation of domestic substitute of leuprorelin acetate microspheres for 24 weeks. Results: Mean testosterone was 431.4 ng/dL, 119.3 ng/dL, 28.2 ng/dL by week 1, 2, 3 and decreased to less than 15.6 ng/dL by week 4 where it remained throughout the treatment period. Median time to suppression of serum testosterone was 20.7 days. No transient minor 'escape' from suppression occurred in all patients which was defined as a single testosterone value greater than 50 ng/dL once suppression was achieved. Assessment of agonistic stimulation following the second depot injection revealed no pattern of stimulation. Conclusion: We concluded that monthly(3.75 mg) depot formulation of domestic substitute of leuprorelin acetate microspheres could provide persistent, stable suppression of serum testosterone throughout the dosing intervals, and that the initial depot injection of this formulation also could provide sufficient pituitary desensitization to prevent agnostic stimulation of serum testosterone during chronic treatment. | Dongliang Pan Liming Dong Lianchao Jin Bing Yang Zhe Zhou Kai Zhang Xianghua Zhang Ningchen Li | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，7： | 1 |

| 15 | Microbial and metabolomic mechanisms mediating the effects of dietary inulin and cellulose supplementation on porcine oocyte and uterine development显示文摘Background:Dietary fiber(DF)is often eschewed in swine diet due to its anti-nutritional effects,but DF is attracting growing attention for its reproductive benefits.The objective of this study was to investigate the effects of DF intake level on oocyte maturation and uterine development,to determine the optimal DF intake for gilts,and gain microbial and metabolomic insight into the underlying mechanisms involved.Methods:Seventy-six Landrace×Yorkshire(LY)crossbred replacement gilts of similar age(92.6±0.6 d;mean±standard deviation[SD])and body weight(BW,33.8±3.9 kg;mean±SD)were randomly allocated to 4 dietary treatment groups(n=19);a basal diet without extra DF intake(DF 1.0),and 3 dietary groups ingesting an extra50%(DF 1.5),75%(DF 1.75),and 100%(DF 2.0)dietary fiber mixture consisting of inulin and cellulose(1:4).Oocyte maturation and uterine development were assessed on 19 d of the 2nd oestrous cycle.Microbial diversity of faecal samples was analysed by high-throughput pyrosequencing(16S r RNA)and blood samples were subjected to untargeted metabolomics.Results:The rates of oocytes showing first polar bodies after in vitro maturation for 44 h and uterine development increased linearly with increasing DF intake;DF 1.75 gilts had a 19.8%faster oocyte maturation rate and a 48.9 cm longer uterus than DF 1.0 gilts(P<0.05).Among the top 10 microbiota components at the phylum level,8increased linearly with increasing DF level,and the relative abundance of 30 of 53 microbiota components at the genus level(>0.1%)increased linearly or quadratically with increasing DF intake.Untargeted metabolic analysis revealed significant changes in serum metabolites that were closely associated with microbiota,including serotonin,a gut-derived signal that stimulates oocyte maturation.Conclusions:The findings provide evidence of the benefits of increased DF intake by supplementing inulin and cellulose on oocyte maturation and uterine development in gilts,and new microbial and metabolomic insight into the mechanisms mediating the effects of DF on reproductive performance of replacement gilts. | Zhaoyue Men Meng Cao Yuechan Gong Lun Hua Ruihao Zhang Xin Zhu Lianchao Tang Xuemei Jiang Shengyu Xu Jian Li Lianqiang Che Yan Lin Bin Feng Zhengfeng Fang De Wu Yong Zhuo | 2022 | Journal of Animal Science and Biotechnology2022，13，3： | 1 |

| 17 | On Diffused Pollution Effect of Chemical Fertilizers in Chongqing Municipality显示文摘Improper use of chemical fertilizers is an essential reason for diffused pollution of agriculture. Therefore,finding out influence factors of farmers in application of chemical fertilizers will play a significant role in controlling the diffused pollution of agriculture. Through field survey,a total of 340 samples in 4 counties of Chongqing Municipality were obtained. On the basis of these samples,an empirical study was carried out. The study results indicate that farmers' application of chemical fertilizers is negatively correlated with farmers' age,education level,male labor proportion,and soil fertility,while the annual family income,agricultural production population proportion,commodity trading characteristics,and scientific fertilizer application ability fail to pass the significance test. These results will provide reference for proper application of chemical fertilizers and controlling diffused pollution. | Limeng GU Lianchao YU Qian BI | 2015 | Asian Agricultural Research2015，7，6： | 0 |

| 20 | Composition optimization of inconel 718 via cluster formula and experimental verification显示文摘Superalloys feature multi-elements and complex elemental ranges,which makes the proper composition selection difficult.In fact,more strict composition standards generally apply in practical productions.The objective of this paper is to understand and eventually to renew the composition standard via example of the most common grade Inconel 718.We have recently shown that t he alloy chemistry originates from a nearest-neighbor cluster[center-shell]plus a few next-neighbor glue atoms,or expressed in cluster for-mula[center-shell](glue atoms).By grouping the elements into Ni=(Ni,Co,Cu,Fe),Cr=(Cr,Mn,Si,Mo),and Nb=(Nb,Al,Ti),it is found that the reported alloys fall within a narrow composition zone Ni_(11.0-13.0)-Cr_(3.5-4.5)-Nb_(1) confined by cluster formulas of 16 and 18 atoms.This composition zone is also expressed in terms of 288-atom supercluster formulas,Ni_(198-208)-Cr_(63-72)-Nb_(16-18),which leads to coordi-nated elemental variations in wt.%:69.0≤Ni+Co+Cu+Fe≤72.7;19.8≤Cr+Mn+1.7 Si+0.6 Mo≤22.8;8.7≤Nb+3.2 Al+1.9 Ti≤9.8.Within this composition zone,Ni_(206)-Cr_(65.5)-Nb_(16.5) is further pinpointed and validated by our own experiments to possess the optimal match of strength and plasticity both at room and at 923 K. | Yancheng Li Mo Li Qing Wang Yajun Zhao Shuang Zhang Cunlei Zou Ying Li Lianchao Wang Chuang Dong | 2023 | Journal of Materials Science & Technology2023，，9： | 0 |
