| 3 | MHD Flow Control of Oblique Shock Waves Around Ramps in Low-temperature Supersonic Flows显示文摘This article is devoted to experimental study on the control of the oblique shock wave around the ramp in a low-temperature supersonic flow by means of the magnetohydrodynamic(MHD) flow control technique.The purpose of the experiments is to take advantage of MHD interaction to weaken the oblique shock wave strength by changing the boundary flow characteristics around the ramp.Plasma columns are generated by pulsed direct current(DC) discharge,the magnetic fields are generated by Nd-Fe-B rare-earth permanent magnets and the oblique shock waves in supersonic flow are generated by the ramp.The Lorentz body force effect of MHD interaction on the plasma-induced airflow velocity is verified through particle image velocimetry(PIV) measurements.The experimental results from the supersonic wind tunnel indicate that the MHD flow control can drastically change the flow characteristics of the airflow around the ramp and decrease the ratio of the Pitot pressure after shock wave to that before it by up to 19.66%,which leads to the decline in oblique shock wave strength.The oblique shock waves in front of the ramp move upstream by the action of the Lorentz body force.The discharge characteristics are analyzed and the MHD interaction time and consumed energy are determined with the help of the pulsed DC discharge images.The interaction parameter corresponding to the boundary layer velocity can reach 1.3 from the momentum conservation equation.The velocity of the plasma column in the magnetic field is much faster than that in the absence of magnetic field force.The plasma can strike the neutral gas molecules to transfer momentum and accelerate the flow around the ramp. | Su Changbing,Li Yinghong,Cheng Bangqin,Wang Jian,Cao Jun,Li Yiwen Engineering College,Air Force Engineering University,Xi’an 710038,China | 2010 | Chinese Journal of Aeronautics2010,23,1: | 15 |
| 4 | Reverse reconciliation for continuous variable quantum key distribution显示文摘An efficient and practical post-processing technique based on reverse reconciliation for continuous variable quantum key distribution is proposed and simulated with low-density parity check (LDPC) codes. MultiLevel Coding/ MultiStage Decoding, which fully utilizes optimization technique such as vector quantization and iterative decoding and the optimal channel coding most close to the Shannon limit, was used to realize efficient reverse reconciliation algorithm. Simulation results showed that the proposed method can improve the secure key distribution rate to 2.2 kb/s and the coding efficiency to 0.89 over 20 km in single-mode optical fiber. Moreover, there still is room for much improvement. | LU ZhiXin 1,2 , YU Li 1,2 , LI Kang 1,2 , LIU BingCan 1,2,3 , LIN JianGui 1,2 , JIAO RongZhen 1,2 & YANG BoJun 1,21 School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China 2 Key Laboratory of Information Photonics and Optical Communication, Ministry of Education, Beijing University of Posts and Telecommunications, Beijing 100876, China 3 Department of Fundamental Courses, Academy of Armored Force Engineering, Beijing 100072, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010,53,1: | 12 |

| 6 | Preliminary study on interaction between plant frictional root and rock-soil mass显示文摘The interaction between lateral root system of woody plant and soil mass is similar to the one between shrub, herbage and soil mass, and has the effect of frictional reinforcement on slope soil. It plays an important role in reinforcing soil strength in shallow slope. Therefore, slope soil mass can be considered as a composite of soil and plant roots and the soil strength and stability of shallow slope soil mass are improved. However, current researches still remain on the level of qualitatively analyzing the relation between root and soil mass. In this paper, some exploratory researches on quantitative analysis of the interaction mechanism between root and soil mass are conducted. With the study of interaction between herbage root system (lateral root system of woody plants) and soil mass, the mechanical model of interaction between frictional root and soil mass is established. The accuracy of the model is verified by field experiments of Pinus Yunnanensis. The mechanical model provides a crucial theoretical guidance to quantitatively analyzing the interaction between plant root and soil mass; it also has certain values in application. | YAN ZhiXin1’2, SONG Yun3, JIANG Ping1’2 & WANG HouYu4 1 Key Laboratory of Mechanics on Disaster and Environment in Western China (Lanzhou University), Ministry of Education, Lanzhou 730000, China 2 School of Civil Engineering and Mechanics, Lanzhou University, Lanzhou 730000, China 3 College of Civil Engineering and Mechanics, Central South University of Forestry and Technology, Changsha 410004, China 4 Air Force Engineering Design & Research Bureau, Beijing 100077, China | 2010 | Science China(Technological Sciences)2010,53,7: | 9 |

| 8 | A novel two-layered optical satellite network of LEO/MEO with zero phase factor显示文摘Optical satellite communication has advantages over the RF satellite communication in capacity, speed, secrecy and anti-interference.Space information superhighway composed of GEO/MEO/LEO satellites which are linked by optical inter-satellite links(OISL) would play important roles in communication, navigation, martial recon, remote sensing and deep space exploration.A novel LEO/MEO two-layered optical satellite network with global coverage is designed with the street-of-coverage technique.The layer of LEO satellites is the walker-delta constellation with zero phase factor and has the quasi-stable logical structure of Mesh.Equatorial and polar orbit satellites constitute the layer of MEO satellite, which can cover LEO layer effectively.Rising satellites of the system can provide 99.9% of coverage for the whole globe and 100% for China averagely.The network can provide a minimum elevation angle at 21 ? with single-satellite visibility for China, and at 16 ? with the dual-satellite visibility.Simulation results of the inter-satellite links show LEO constellation of zero phase factor outperforms non-zero phase factor constellations in azimuth angle, elevation angle and distance, which is very fit for the OISL.Simulation results of the communication performance indicate a little difference between short wave band and long wave band at low communication speed(several Gbit/s);however, the wave band at 1550 nm is a better choice at high communication speed(100 Gbit/s). | LI YongJun , WU JiLi, ZHAO ShangHong, MENG Wen, MA LiHua, SHI Lei, CHU XingChun, HOU Rui & LI Tian Telecommunication Engineering Institute, Air Force Engineering University, Xi’an 710077, China | 2010 | Science China(Information Sciences)2010,53,6: | 8 |

| 11 | The ratio of MMP-2 to TIMP-2 in hilar cholangiocarcinoma:a semi-quantitative study显示文摘BACKGROUND: Hilar cholangiocarcinoma is associated with low resectability and poor survival. The aim of this study was to evaluate the roles of matrix metalloproteinases- 2 (MMP-2 ) and its tissue inhibitor of metalloproteinase-2 (TIMP-2) in tumor invasion or as a prognostic factor in patients with human hilar cholangiocarcinoma. METHODS: The expressions of MMP-2 and TIMP-2 were investigated in patients. Paraffinized tissue sections ob- tained from 50 patients with human hilar cholangiocarcino- ma were analysed. The expressions of MMP-2 and TIMP-2 were examined immunohistochemically. Image analysis with image-pro plus analysis software was used to semi- quantitatively determine the ratio of MMP-2 to TIMP-2. RESULTS: The expression levels of MMP-2 and TIMP-2 were strongly associated with tumor hepatic invasion in pa- tients with hilar cholangiocarcinoma. Significant diffe- rences in the ratio of MMP-2 to TIMP-2 between some pathologic factors were observed in patients with hilar cholangiocarcinoma. CONCLUSIONS: MMP-2 plays an essential role in tumor invasion and metastasis,while TIMP-2 is shown to strongly inhibit cancer invasion and metastasis. The ratio of MMP-2 to TIMP-2 may be a prognostic indicator for patients with hilar cholangiocarcinoma. | Mei Xiao, Nin-Xing Zhou,Zhi-Qiang Huang,Ya-Li Lu, Ling-Hong Chen, Dian-Jun Wang and Wei-Lin Chang Beijing, China Department of Hepatobiliary Surgery, General Air- force of Hospital, Beijing 100036, China and General Hospital of People’ s Liberation Army, Beijing 100853 , China | 2004 | Hepatobiliary & Pancreatic Diseases International2004,3,4: | 5 |

| 14 | WROUGHT TiAl ALLOY DESIGN显示文摘Empirical improvements made in cast alloys have led to gamma alloys which are a viable materials technology, and to the development of various applications for gas turbine engines, as well as automotive engines. For wrougth alloys, over the last seven years the author et al have made extensive efforts to remove their deficiencies, and to achieve an improved balance of properties, across three interrelated task areas. The first effort was directed toward understanding fundamentals, such as phase relations, microstructure evolution, and microstructure property relationships. The second task was then directed to improve the balance of properties through designing refined lamellar microstructures and microalloying. The third effort was to explore the production methods to develop desired microstructures and to optimize the alloy compositions. This paper discusses the progress made from the last two efforts. | Young Won Kim Materials and Manufacturing Directorate, Air Force Research Laboratory Wright Patterson AFB, OH 45433, U. S.

| 16 | MAPKs and Mst1/Caspase-3 pathways contribute to H2B phosphorylation during UVB-induced apoptosis显示文摘Apoptosis is a highly coordinated or programmed cell suicide mechanism in eukaryotes.Histone modification is associated with nuclear events in apoptotic cells.Specifically H2B phosphorylation at serine 14 (Ser14) catalyzed by Mst1 kinase has been linked to chromatin condensation during apoptosis.We report that activation of MAPKs (ERK1/2,JNK1/2 and p38) together with Mst1 and caspase-3 is required for phosphorylation of H2B (Ser14) during ultraviolet B light (UVB)-induced apoptosis.UVB can trigger activation of MAPKs and induce H2B phosphorylation at Ser14 but not acetylation in a time-dependent manner.Inhibition of ERK1/2,JNK1/2 or p38 activity blocked H2B phosphorylation (Ser14).Furthermore,caspase-3 was activated by UVB to regulate Mst1 activity,which phosphorylates H2B at Ser14,leading to chromatin condensation.Full inhibition of caspase-3 activity reduced Mst1 activation and partially inhibited H2B phosphorylation (Ser14),but ERK1/2,JNK1/2 and p38 activities were not affected.Taken together,these data revealed that H2B phosphorylation is regulated by both MAPKs and caspase-3/Mst1 pathways during UVB-induced apoptosis. | LU ChengRong1SHI Ying1LUO Yuan1,DUAN LianNing1,HOU Yong2,HU HongBo3,WANG Zhe1 & XIANG PeiDe1 1Aviation Medicine Research Laborabory,General Hospital of Air Force,Beijing 100142,China 2 Department of Pharmacology,Hebei North University,Zhangjiakou 075000,China 3 Nutrition and Food Safety Center,College of Food Science and Nutritional Engineering,China Agricultural University,Beijing 100083,China | 2010 | Science China(Life Sciences)2010,53,6: | 3 |
| 17 | Microstructure and Tribological Properties of PlasmaSprayed Ni/MoS_2 Solid Lubrication Coating显示文摘A composite Ni based MoS2 solid lubrication coating was prepared using the plasma spraying technology with optimized process parameters.The tribological properties of the composite Ni/MoS2 coatings in air and vacuum were studied with a ball-on-disk friction and wear tester under dry sliding condition,respectively.XRD,SEM and EDS were adopted to analyze the microstructures of the coating before and after wear tests.Results showed that the deposition quality of the coating was good.The content of lubricant MoS2 was high.But the compactability of the coating with many superficial micrometersized defects such as pores and cracks was relatively low.The composite Ni/MoS2 coating exhibited excellent friction-reduction properties both in air and in vacuum conditions.In vacuum,the wear loss was greater because the severe spalling of top layer resulted from breakthrough of the adjacent defects.In air condition,the wear loss of the coating was relatively low but its friction-reduction ability may be weakened for the oxidation of MoS2. | Ma Guozheng,Xu Binshi,Wang Haidou,Yang Daxiang National Key Laboratory for Remanufacturing,Academy of Armored Forces Engineering,Beijing 100072,China | 2012 | 稀有金属材料与工程2012,41,S1: | 3 |

| 19 | Study of the effect of atorvastatin on the interaction between ICAM-1 and CD11b by live-cell single-molecule force spectroscopy显示文摘The interaction between the cell adhesion molecule CD11b and its ligand ICAM-1 plays an important role in inflammatory responses in the disease of atherosclerosis. Atorvastatin is a commonly prescribed statin drug which has been considered as one of the most potent therapeutic agents for atherosclerosis due to its lipid-lowering effect. Recently, there is a growing body of evidence that atorvastatin has anti-inflammatory effect. We have applied the advanced method of live-cell single-molecule force spectroscopy to investigate the effect of atorvastatin on adhesion force between ICAM-1 and CD11b. Our result showed that single-molecule binding force of ICAM-1 and CD11b detected by AFM in the living cells was about 40 pN, and atorvastatin did not affect this force by blocking ICAM-1 or CD11b. This was different from the ICAM-1 monoclonal antibody, which could directly reduce the binding force of ICAM-1 and CD11b. Flow cytometry results revealed that atorvastatin pretreatment decreased the ICAM-1 expression in TNF-α activated HUVECs, which may contribute to its anti-inflammatory effect. The study provides a new approach to study anti-inflammatory mechanism for clinic drugs. | LI Yi1, SHI XiaoLi2, LIU HuiLiang1, YI ShaoQiong3, ZHANG XueJie2 & FANG XiaoHong2 1Department of Cardiology, the General Hospital of Chinese People’s Armed Police Forces, Beijing 100039, China 2Beijing National Laboratory for Molecular Sciences Institute of Chemistry, Chinese Academy of Sciences, Beijing 100190, China 3State Key Laboratory of Pathogen and Biosecurity Beijing Institute of Microbiology and Epidemiology, Beijing 100071, China | 2010 | Science China Chemistry2010,53,4: | 2 |
