| 1 | Gene cloning and expression of cadherin in midgut of Helicoverpa armigera and its Cry1A binding region显示文摘Cadherins belong to one of the families of animal glycoproteins responsible for cal-cium-dependent cell-cell adhesion. Recent literatures showed that the cadherin-like in midgut of several insects served as the receptor of Bt toxin Cry1A and the variation of cadherin-like is re-lated to insect’s resistance to Cry1A. The full-length cDNA encoding cadherin-like of Helicoverpa armigera is cloned by degenerate PCR and RACE techniques and the gene was designated as BtR-harm, which is 5581 bp in full-length, encoding 1730 amino acid residues (BtR-harm was deposited in GenBank and the accession number is AF519180). Its predicted molecular weight and isoelectric point were 195.39 kDa and 4.23, respectively. The inferred amino acid sequence includes a signal sequence, 11 cadherin repeats, a membrane-proximal region, a transmem-brane region and a cytoplasmic region. Sequence analysis indicated that the deduced protein sequence was most similar to the cadherin-like from Heliothis virescens with 84.2% identity and highly similar to three other lepidopteran cadherin from Bombyx mori, Manduca sexta and Pectinophora gossypiella, with the sequence identities of 60.3.6%, 57.5% and 51.0%, respec-tively. The cDNA encoding cadherin gene was expressed successfully in E. coli and the recom-binant proteins can bind with Cry1Ac. Truncation analysis and binding experiment of BtR-harm revealed that the Cry1A binding region was a contiguous 244-amino acid sequence, which lo-cated between amino acid 1217 and 1461. Semi-quantitative RT-PCR analysis showed that BtR-harm was highly expressed in midgut of H. armigera, very low expressed in foregut and hindgut and was not expressed in other tissues. After H. armigera producing resistance to Cry1Ac, the expression quantity of BtR-harm significantly decreased in midgut of H. armigera. It is the first confirmation that BtR-harm can function as receptor of Cry1Ac in H. armigera and the binding region was located on a contiguous 244 amino acid sequence, suggesting that the de-crease of expression quantity of BtR-harm is one of the main reasons for H. armigera resistance to Cry1Ac. | WANG Guirong WU Kongming LIANG Gemei GUO Yuyuan | 2005 | Science China(Life Sciences)2005，48，4： | 17 |
| 2 | Wideband electromagnetic characteristics modeling and analysis of missile targets in ballistic midcourse显示文摘The wideband electromagnetic characteristics of missile targets in midcourse are the foundation of midcourse attack-defense confrontation.This paper proposes a novel electromagnetic scattering modeling method for midcourse targets based on a precise scattering center model,in which the nonideal scattering phenomenon,shielding effect and micro-motion are taken into consideration for the first time.Firstly,a precise scattering center model incorporating both the sliding scattering and anisotropic scattering is established.Then the change rule of the target attitude is generalized,and a checking method of the scattering center shielding effect is proposed for rotationally symmetric targets.Afterwards,a novel dynamic electromagnetic scattering model is presented,where the scattering center model updates along with the variation of the target attitude and can characterize the change of the electromagnetic characteristics of midcourse targets exactly.Finally,in light of the established model,the dynamic electromagnetic characteristics within different attitude angle bounds are analyzed by stages,and some useful conclusions are obtained.Experiment results from the measured data in anechoic chamber verify the validity of the proposed modeling method and relevant analysis. | XU ShaoKun LIU JiHong WEI XiZhang LI Xiang GUO GuiRong | 2012 | Science China(Technological Sciences)2012，55，6： | 11 |

| 4 | Nonuniform stretch processing for the range profile of a target with micro-motion显示文摘Complex motions such as micro-motions induce complex range-Doppler coupling effect in radar imaging. Hence, it is a challenge to reconstruct a clear range profile of a target with micro-motion. Stretch processing with fine motion compensation cannot perform well while it ties to eliminate the distortion of range profile caused by Doppler effect, because it is difficult to accurately estimate each scattering center velocity during coherent processing interval. Based on nonuniform stretch processing (NSP), a new technology is proposed to decouple range, time and Doppler and then achieve range profile of target with micro-motion. The new technology uses a new synthetic wide-band waveform and has an innovative mathematic interpretation. Statistical properties of the new approach are primarily examined. Typical models of target with micro-motion for high resolution radar are presented. Monte Carlo simulations demonstrate the performance of the new technology and the simulation results confirm our expectations. | CHEN Hangyong JIANG Weidong LIU Yongxiang LI Xiang GUO Guirong | 2006 | Progress in Natural Science:Materials International2006，16，11： | 4 |
| 5 | Photoluminescence Properties of Porous Silicon Based on FZ(H) Si Wafer显示文摘The photoluminescence (PL) properties of porous silicon (PS) have been studied based on n-type single- crystal (111) silicon wafers (80-90Ω .cm in the resistivity). The porous silicon layers (PSL) were created by anodizing the wafers with a denuded zone of 20-40 μm formed by neutron transmutation doping (NTD) and thermal treatment at 940℃ for 4 h and then 700℃ for 2 h, two-step heating of the floating-zone silicon (FZ Si) grown in a hydrogen (H2) ambience. By surface modification with stannic chloride or amine immersion and rapid thermal oxidation (RTO), the PL peak position from the PS can be qualitatively controlled factitiously. The as-prepared PS shows an orange-yellow luminescence, while the modified samples emit red, green and blue luminescence. Mechanisms for the different colors of the PL are discussed. Fourier transform infrared (FTIR) is carried out to analyze the differences in the structural configuration of the PS samples. | Yuejiao He, Huaixiang Li, Chenghua Guo, Guirong Liu, Yansheng Chen, Shuzhen Duan (Institute of Semiconductors, Shandong Normal University, Jinan 250014, China Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China) | 2001 | Rare Metals2001，20，1： | 2 |

| 12 | MODELING AND SIMULATION OF COMPOUND CLUTTER FOR COASTAL ENVIRONMENT显示文摘This paper introduces a novel clutter power model of coastal compound and deduces the statistic characteristics and the arithmetics of model parameter estimation algorithm. Then, a novel coastal compound distributed model of the clutter amplitude is proposed and its statistic character- istics are studied. Subsequently, the nonlinear relation of autocorrelation function is deduced between the coastal compound clutter random sequences and the correlated Gaussian random sequences, which is the important prerequisite for the clutter simulation based on the ZMNL (Zero Memory NonLin- earity). Lastly, the advantage of the algorithm is demonstrated by a feasible simulation of the gen- eration of the random coastal compound clutter sequences. | Jiang Bin Wang Hongqiang He Xiang Guo Guirong | 2007 | Journal of Electronics(China)2007，24，4： | 0 |
