| 1 | Effects of minor Sc on the microstructure and mechanical properties of Al-Zn-Mg-Cu-Zr based alloys显示文摘Five kinds of Al-Zn-Mg-Cu-Zr based alloys with different Sc additions were prepared by ingot metallurgy. The effects of minor Sc on the microstructure and mechanical properties of Al-Zn-Mg-Cu-Zr based alloys were investigated using tensile tests, optical microscopy (OM), and transmission electron microscopy (TEM). The results show that the ultimate tensile strength and yield strength are improved by 94 and 110 MPa, respectively, and the elongation to failure remains at a reasonable extent (11.1%) in the Al-Zn-Mg-Cu-Zr based alloy with 0.21 wt.% Sc addition after solution heat treatment at 475°C for 40 min and then aged at 120°C for 24 h. The addition of minor Sc induces the formation of Al3(Sc,Zr) particles, which are highly effective in refining the cast microstructures, retarding recrystallization, and pinning dislocations. The increment of strength is attributed mainly to fine grain strengthening, precipitation strengthening of Al3(Sc,Zr) particles, and substructure strengthening. | LI Wenbin PAN Qinglin ZOU Liang LIANG Wenjie HE Yunbin LIU Junsheng | 2009 | Rare Metals2009，28，1： | 12 |
| 2 | The unconformity in Miocene sequence of western Qaidam Basin and its tectonic significance显示文摘An angular unconformity has been identified between the upper and the lower Youshashan Formation based on the study of the regional geology, drillhole, and geophysical data of the Altyn Tagh Mountain foreland, western Qaidam Basin. The distribution of the unconformity, the contacts between the upper and the lower Youshashan Formation, and its relation to the characteristics of the paleo-structure belts suggest a close relationship between the unconformities in the southern flank of the Altyn Tagh Mountain in the west of the Qaidam Basin and the activity of the Altyn Tagh Fault. It was the same time when the Atlyn Tagh Fault Zone was transformed from regional uplifting to rapid-strike-slipping movement during the Miocene, resulting in the cessation of the regional uplift and subsequent massive regional transgression during the deposition of the upper Youshashan Formation, which unconformably overlies (onlaps) the underlying strata of different ages. | WANG Liang XIAO AnCheng GONG QingLin LIU Dong WU Lei ZHOU SuPing SHEN ZhongYan LOU QianQian SUN XiaoWen | 2010 | Science China Earth Sciences2010，53，8： | 10 |

| 5 | Synthesis and Diameter-dependent Thermal Conductivity of InAs Nanowires显示文摘In this work, we synthesized high-quality In As nanowires by a convenient chemical vapor deposition method,and developed a simple laser heating method to measure the thermal conductivity of a single In As nanowire in air. During the measurement, a focused laser was used to heat one end of a freely suspended nanowire, with its other end embedded into a carbon conductive adhesive. In order to obtain the thermal conductivity of In As nanowires, the heat loss in the heat transfer process was estimated, which includes the heat loss through air conduction, the heat convection, and the radiation loss. The absorption ratio of the laser power in the In As nanowire was calculated. The result shows that the thermal conductivity of In As nanowires monotonically increases from 6.4 W m-1K-1to 10.5 W m-1K-1with diameters increasing from 100 nm to 190 nm, which is ascribed to the enhanced phonon-boundary scattering. | Pinyun Ren Xiaoli Zhu Jinyun Han Jinyou Xu Liang Ma Honglai Li Xiujuan Zhuang Hong Zhou Qinglin Zhang Minggang Xia Anlian Pan | 2014 | Nano-Micro Letters2014，6，4： | 2 |

| 8 | Expression of second mitochondria-derived activator of caspases, X-linked inhibitor of apoptosis protein, and caspase-3 in pituitary adenomas显示文摘Studies concerning correlations between pituitary adenomas and cell apoptosis have mainly focused on upstream apoptosis signaling, but seldom on downstream mediators. In the present study, second mitochondria-derived activator of caspases (Smac), X-linked inhibitor of apoptosis protein (XIAP), and caspase-3 protein were qualitatively analyzed using immunohistochemistry, and quantified by western blot. Smac, XIAP, and caspase-3 mRNA expressions were detected by reverse transcription-PCR. Results showed that XIAP protein and mRNA expressions were greater in the invasive pituitary adenoma group compared with the noninvasive pituitary adenoma group. However, Smac and caspase-3 protein and mRNA expressions were lower in the invasive pituitary adenoma group compared with the noninvasive pituitary adenoma group. In the invasive pituitary adenomas, Smac expression was positively correlated with caspase-3 protein and mRNA expression (Protein: r = 0.55, P < 0.01; mRNA: r = 0.50, P < 0.01). Smac and caspase-3 expressions were negatively correlated with XIAP protein and mRNA expression (Protein: r = -0.56, -0.64, P < 0.01; mRNA: r = -0.69, -0.67, P < 0.01). However, no significant differences in correlation among Smac, XIAP, and caspase-3 were detectable in noninvasive pituitary adenomas. These data indicated that high expression of XIAP and low expression of Smac and caspase-3 suppressed cell apoptosis and led to enhanced invasiveness of pituitary adenomas. Thus, Smac, XIAP, and caspase-3 may be useful markers in determining the invasive behavior of pituitary adenomas. | Dong Li Gang Huo Liang Wang Qinglin Feng Maoyuan Tang | 2011 | Neural Regeneration Research2011，6，7： | 1 |
| 9 | ANALYSIS OF WEIGHTED NON-COHERENT RECEIVER FOR UWB-OOK SIGNAL IN MULTIPATH CHANNELS显示文摘Non-coherent receivers are attractive for pulsed Ultra-WideBand (UWB) systems due to the implementation simplicity. However, they have to face the shortage of performance degradation. Several techniques were proposed to alleviate the noise effect and promote the receiver performance, among which is the weighted combining of multiple integration sub-intervals. In this paper, the performance of the weighted non-coherent receiver for UWB On-Off Keying (UWB-OOK) signal in multipath channels is analyzed, in terms of bit-error-rate. In addition, a closed-form expression of the approximately near-optimal weighting coefficient set is derived, and two simple weighting coefficient sets are proposed as well. Finally, the analytic results are verified via the computer simulations, which reveal obvious performance improvements to the conventional energy detector. | Wu Jianjun Liang Qinglin Xiang Haige | 2008 | Journal of Electronics(China)2008，25，1： | 1 |

| 12 | ANALYSIS AND SIMULATION OF QSP BEAMFORMER显示文摘The real Direction Of Arrival (DOA) varies with time in mobile communication system. In such situation, the performance of conventional beamformers will be degraded obviously. Quantum Signal Processing (QSP) beamformer is insensitive to DOA errors, thus it can achieve stable output performance in such circumstance. This letter verified the effectiveness and feasibility of the QSP beamformer by simulation results. | Shi Shuangning Shang Yong Liang Qinglin Liang Bin | 2007 | Journal of Electronics(China)2007，24，6： | 0 |
| 13 | ESTIMATION OF BASIS EXPANSION MODELS FOR DOUBLY SELECTIVE CHANNELS显示文摘By analyzing the relationship between Basis Expansion Model (BEM) and Doppler spectrum, this letter proposed a quasi-MMSE-based BEM estimation scheme for doubly selective channels. Based on the assumption that the basis coefficients are approximately independent and have the same variance for the same channel tap, the quasi-MMSE estimation shows approximately optimal performance and is robust to noise. Moreover, it can avoid a high Peak-to-Average Power Ratio (PAPR) by using continuous pilots. Performance of the proposed estimation scheme has been shown with computer simulations. | Liu Yingnan Gao Yonghui Zhang Nu Liang Qinglin | 2008 | Journal of Electronics(China)2008，25，1： | 0 |
| 14 | Computational multiscale methods for granular materials显示文摘The fine-scale heterogeneity of granular material is characterized by its polydisperse microstructure with randomness and no periodicity. To predict the mechanical response of the material as the microstructure evolves, it is demonstrated to develop computational multiscale methods using discrete particle assembly-Cosserat continuum modeling in micro- and macro- scales, respectively. The computational homogenization method and the bridge scale method along the concurrent scale linking approach are briefly introduced. Based on the weak form of the Hu-Washizu variational principle, the mixed finite element procedure of gradient Cosserat continuum in the frame of the second-order homogenization scheme is developed. The meso-mechanically informed anisotropic damage of effective Cosserat continuum is characterized and identified and the microscopic mechanisms of macroscopic damage phenomenon are revealed. | Xikui Li Yuanbo Liang Youyao Du Ke Wan Qinglin Duan | 2013 | Theoretical & Applied Mechanics Letters2013，3，1： | 0 |

| 16 | Beam fanning effect and image storage in Ce:KNSBN crystal显示文摘A non-synchronously-numerating experimental system is applied in this research.The effect of the incident beam intensity I and the beam incident angleθon beam fanning effect is investigated with a singular beam incident on Ce:KNSBN crystal.The results show that the beam fanning effect strongly depends on I andθ.The threshold effect of I for the beam fanning in Ce:KNSBN crystal is observed,and the threshold intensity of incident beam keeps the same value of 38.2 mW/cm 2 for differentθ,and the steady beam fanning intensity Ifsat reaches a peak atθ=15°under the same I.In addition,the effect of the incident beam modulated on the beam fanning noise and holographic storage in Ce:KNSBN crystal is studied.And the results suggest that the beam fanning noise is effectively suppressed,and the quality of the reappearance image is greatly improved. | LI PanLai GUO QingLin WANG ZhiJun PANG LiBin LIANG BaoLai | 2007 | Chinese Science Bulletin2007，52，8： | 0 |
