| 1 | Research on Kalman-filter based multisensor data fusion显示文摘Multisensor data fusion has played a significant role in diverse areas ranging from local robot guidance to global military theatre defense etc.Various multisensor data fusion methods have been extensively investigated by researchers,of which Klaman filtering is one of the most important.Kalman filtering is the best-known recursive least mean-square algorithm to optimally estimate the unknown states of a dynamic system,which has found widespread application in many areas.The scope of the work is restricted to investigate the various data fusion and track fusion techniques based on the Kalman Filter methods,then a new method of state fusion is proposed. Finally the simulation results demonstrate the effectiveness of the introduced method. | Chen Yukun Si Xicai Li Zhigang | 2007 | Journal of Systems Engineering and Electronics2007，18，3： | 11 |
| 2 | Heat transfer process of roadway embankments with different type and width of road surface in permafrost regions显示文摘自从它被热条件管理,在永久冻土区域的路基的稳定性在当前的气候变化下面在这些区域与高速公路,高速公路和铁路的快速的开发和建设成为了一颗大担心,或换句话说,在堤的热转移过程。我们执行了有限元素分析在堤热转移过程上分析道路表面的不同类型的效果和堤的宽度的效果。结果显示在有沥青表面的车道堤的底部的吝啬的年度热转移率与沙的石子表面是乘那的 3。当沥青表面的宽度被加倍时,这意味着转移率增加了 60% 的年度热。增加的热转移率主要在堤的底部被定位并且导致了热集中的效果,导致到差不多 1.6 次的永久冻土的降级。增加的堤高度不减少热转移率的这些增加,这也被发现。因此,两沥青道路表面和增加的堤宽度能在车道堤导致加强的热转移率,因而 degradating 内在的永久冻土和堤不稳定性。 | YU Qihao PAN Xicai CHENG Guodong BAI Yang | 2007 | Progress in Natural Science:Materials International2007，17，3： | 7 |
| 3 | FEEDING HABITS OF HAINAN ELDI'S DEER显示文摘Hainan eldi’s deer is a precious species of deer in the tropic zone,it is regardedas the first—class animal under protection in China.Based on all-year-round observation on thedeer’s feeding habit in the reserve from 1985 to 1988,we discovered that Hainan eldi’s deer is aeuryphangous herbivore.They take various herbs as their main food and have fairly strongselectivity for woody plants,especially tending to eat the tender parts of plants and some fruits andflowers.Like other species of deer,they also like to lick the alkaline soil.This paper reports the re-search and evaluation on the feeding and choosing food characteristics of Hainan eldi’s deer,and onthe palatability of the main plants in the reserve. | Yuan Xicai Liu Xiaoming Wang JunSouth China Institute of Endangered AnimalsFu GuoaiThe Forestry Bureau of Hainan ProvinceLi ShanyuanThe Datian Reserve of Hainan Province | 1991 | Journal of Northeast Forestry University1991，2，1： | 5 |
| 4 | New method for passive radar seeker to antagonize non-coherent radar decoy显示文摘Using super resolution direction of arrival(DOA) estimation algorithm to reduce the resolution angle is an effective method for passive radar seeker(PRS) to antagonize non-coherent radar decoy.Considering the power and correlation property between radar and non-coherent decoy,an improved subspace DOA estimation method based on traditional subspace algorithm is proposed.Because this new method uses the invariance property of noise subspace,compared with traditional MUSIC algorithm,it shows not only better resolution in condition of closely spaced sources,but also superior performance in case of different power or partially correlated sources.Using this new method,PRS can distinguish radar and non-coherent decoy with good performance.Both the simulation result and the experimental data confirm the performance of the method. | Weijian Si,Xicai Si,and Zhiyu Qu College of Information and Communication Engineering,Harbin Engineering University,Harbin 150001,P.R.China | 2010 | Journal of Systems Engineering and Electronics2010，21，3： | 4 |
| 5 | Efficacy of Sijunzi decoction(四君子汤) on limb weakness in spleen Qi deficiency model rats through adenosine monophosphate-activated protein kinase/unc-51 like autophagy activating kinase 1 signaling显示文摘OBJECTIVE:To investigate the efficacy of Sijunzi decoction(四君子汤)on limb weakness in a rat model of spleen Qi deficiency(SQD),and to study its effect on mitophagy in skeletal muscle through adenosine monophosphate-activated protein kinase(AMPK)/unc-51 like autophagy activating kinase 1(ULK1)signaling.METHODS:SQD model rats were produced by fasting combined with forced swimming method for15 d.After model assessment,rats were randomly divided into four groups of 10[low/middle/high(L/M/H)Sijunzi decoction dose groups and a normal saline(S)group].Limb holding power(HP)and body mass(BM)were measured after 2 weeks of treatment.Following euthanasia,quadriceps femoris were dissected and myofiber and mitochondrial morphology were observed by transmission electron microscopy(TEM).Mitochondrial membrane potential(MMP),adenosine triphosphatase(ATP)and reactive oxygen species(ROS)levels were determined using colorimetric methods,and immunoblot analysis of Microtubule-associated protein light chain 3(LC3)and Sequestosome 1(p62)was performed to monitor mitophagy and AMPK/ULK1 signaling.RESULTS:Compared with control(C)group rats,in the S group,HP was reduced,the myofiber Z line was disordered,mitochondria were scattered,and numerous vacuoles and mitophagy were observed.MMP and ATP levels were reduced,ROS levels were elevated,and LC3B expression,and p-AMPKα(Thr172)/AMPKα,p-ULK1(Ser555)/ULK1,and p-Raptor(Ser792)/Raptor ratios were increased,while p62 expression and p-mT OR(Ser2448)/mT OR and p-ULK1(Ser757)/ULK1 ratios were decreased.After treatment,compared with the S group,HP was improved in M and H groups but not in the L group.Mitophagy was reduced in M,H and L groups but the Z line was disordered and vacuolization remained in the L group.ATP levels were elevated in M,H and L groups,and MMPs were elevated in M and H groups but not in the L group.ROS levels were decreased in M,H and L groups,as were LC3B expression and p-Raptor(Ser792)/Raptor ratios,while p62 expression and p-mT OR(Ser2448)/mT OR and p-ULK1(Ser757)/ULK1 ratios were increased in M and H groups but not in the L group.p-AMPKα(Thr172)/AMPKαand p-ULK1(Ser555)/ULK1 ratios were decreased in M,H and L groups.CONCLUSIONS:Sijunzi decoction improved HP,possibly by inhibiting mitophagy via suppression of AMPK/ULK1 signaling.This restored mitochondrial morphology and improved oxidative phosphorylation,which contributed to recovery of limb weakness in SQD model rats. | LIU Wenjun XU Xinzhu DUAN Zhiyuan LIANG Xicai MA Dan LI Gege XIE Xin CHAI Jiyan CHEN Jing SHAN Dehong | 2021 | Journal of Traditional Chinese Medicine2021，41，4： | 2 |

| 8 | Shared-network scheme of SMV and GOOSE in smart substation显示文摘The network structure of the smart substation in common use was introduced,and the technical problems of the shared-network of sampled measured value(SMV)and generic object oriented substation event(GOOSE)were analyzed,such as the processing ability of network device and the intelligent device,the data real-time property and the network reliability,the effects to the substation in the condition of network fault,etc.On this basis,the feasibility of the shared-network of SMV and GOOSE was discussed,the implement scheme was presented,and eventually the solution of the shared-network of SMV and GOOSE was put forward,which based on the applications of the message priority control,restricting the switch number,virtual local area network(VLAN)and GARP multicast registration protocol(GMRP)classification flow control,flow rate limiting,etc.In the test-bed,the cases of shared-network and separate-network of SMV and GOOSE were compared and analyzed,and the result was valuable for reference. | Wenlong WANG Minghui LIU Xicai ZHAO Gui YANG | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，4： | 1 |
| 9 | Zircon U-Pb age and Hf isotopic characteristics of the Huangtuliang monzonitic granite, North Hebei Province, China显示文摘The Huangtuliang monzonitic granite outcrops on the northern side of the Huangtuliang gold mining district, Chicheng, North Hebei Province. Our predecessors only made isotopic age determination using the K-Ar method. Through LA-MC-ICP-MS zircon U-Pb dating and zircon Hf isotopic composition determination, this study acquired the age of 244.8±2.0 Ma(MSWD=0.57) on the basis of the weighed mean 206Pb/238U ratio, indicating that the Huangtuliang monzonitic granite was formed during the Middle Triassic period, which is the product of Early Indosinian magmatic activities in the region of North Hebei. εHf(t) values vary relatively evenly, within the range of-10.65--14.03, with an average of-12.14. The two-stage evolution model ages, tDM2, vary between 1943 and 2144 Ma, implying that the rock-forming materials of the Huangtiliang monzonitic granite mainly came from the Paleoproterozoic recirculated crustal materials, though a small quantity of enriched-mantle materials would have been involved. | HU Huabin NIU Shuyin ZHANG Zhanyang TIAN Ye LIU Xiaoyu CHEN Xicai CHEN Haijiao | 2014 | Chinese Journal Of Geochemistry2014，33，1： | 1 |

| 18 | miR-30a-5p/PHTF2 axis regulates the tumorigenesis and metastasis of lung adenocarcinoma显示文摘Background:Lung adenocarcinoma is a very pervasive histological form of lung cancers,and inhibiting metastasis is crucial for effective treatment.In this investigation,we explored the functional interaction of miR-30a-5p and the putative transcription factor 2 of the homeodomain(PHTF2)in dictating the aggressiveness and metastasis of lung adenocarcinoma.Method:We collected clinical samples to evaluate the expression patterns of miR-30a-5p and PHTF2 in lung adenocarcinoma along with normal tissues.Cellular experiments including cell count kit(CCK)-8 growth assay,apoptosis analysis,migration and invasion examinations were performed to assess the aggressiveness of lung adenocarcinoma cells.Furthermore,we examined tumorigenesis and metastasis in a nude mouse model.Results:MiR-30a-5p exhibited downregulation pattern in lung adenocarcinoma samples.Transfection of miR-30a-5p mimic in lung adenocarcinoma cells resulted in the suppression of malignant characteristics.Notably,the administration of miR-30a-5p mimic also curbed tumorigenesis and metastasis of lung adenocarcinoma cells in animal model.Moreover,PHTF2 was found to be a molecular target of miR-30a-5p.Upregulating PHTF2 counteracted the tumor-suppressive effect of the miR-30a-5p mimic.Conclusion:miR-30a-5p functions as a tumor-suppressive molecule while PHTF2 acts as an oncogenic factor in the development and metastasis of lung adenocarcinoma.Therefore,targeting miR-30a-5p and PHTF2 could be developed into a promising therapeutic approach for inhibiting metastasis in lung adenocarcinoma. | LIJUAN ZHANG QINGYIN MENG LI ZHUANG QUAN GONG XIANDA HUANG XUEQIN LI SHIJUAN LI GUOQIN WANG XICAI WANG | 2024 | BIOCELL2024，48，4： | 0 |
| 19 | Method for determining number of coherent signals in the presence of colored noise显示文摘The approach of estimating the number of signals based on information theoretic criteria has good performance in the assumption of white noise, but it always leads to false estimation of the coherent sources in colored noise. An approach combining the combined information theoretic criteria and eigenvalue correction, is presented to determine number of signals. The method uses maximum likelihood (ML) and information theoretic criteria to estimate coherent signals alternately, then eliminate the inequality of the eigenvalues caused by colored noise by correcting the noise eigenvalues. The computer simulation results prove the effective performance of the method. | Jiaqi Zhen, Xicai Si, and Lutao Liu College of Information & Communication Engineering, Harbin Engineering University, Harbin 150001, P.

| 20 | Achieving Superior Superplasticity in a Mg-6Al-Zn Plate via Multi-pass Submerged Friction Stir Processing显示文摘A large-scale Mg-6Al-Zn plate was prepared by multi-pass submerged friction stir processing(M-SFSP)and its superplastic deformation behavior was investigated.The maximum elongation of 467%,332%and 421%was attained for the samples oriented in the processing direction(PD),45°tilted toward the PD,and transverse direction(TD),respectively,when deformed at 623 K and a strain rate of 1×10^(−3) s^(−1).This was attributed to the homogeneous and fine-grained structure with mostly high-angle grain boundaries facilitating the prevalent deformation mechanism of grain boundary sliding,along with the weakened texture and dynamic recrystallization during hot deformation. | Xicai Luo Haolin Liu Limei Kang Jielin Lin Datong Zhang Dongyang Li Daolun Chen | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，5： | 0 |
