	Correlations between neutrons and protons near the Fermi surface and Q(alpha) of superheavy nuclei 期刊论文 OAI收割 PHYSICAL REVIEW C, 2016, 卷号: 93, 期号: 1, 页码: 14302 作者: \| 收藏 \| 浏览/下载：61/0 \| 提交时间：2017/10/13 The Shell Corrections And Shell Gaps In Nuclei Are Systematically Studied With The Latest Weizsacker-skyrme (Ws4) Mass Model. We Find That Most Of Asymmetric Nuclei With (Sub) Shell Closures Locate Along The Shell Stability Line (Ssl) n=1.37z+13.5 Which Might Be Due To a Strong Correlation Between Neutrons And proTons Near The Fermi Surface. The Double Magicity Of Nuclei Si-46 And Ni-78 Is Predicted According To The Corresponding Shell Gaps Shell Corrections And Nuclear Deformations. The Unmeasured Superheavy Nuclei (296)118 And (298)120 With Relatively Large Shell Gaps And Shell Corrections Also Locate Along The Ssl Whereas The Traditional Magic Nucleus (298)F1 Evidently Deviates From The Line. The Alpha-decay Energies Of Superheavy Nuclei With Z=113-126 Are Simultaneously Investigated By Using The Ws4 Model togeTher With The Radial Basis Function Corrections. For Superheavy Nuclei With Large Shell Corrections The Smallest Alpha-decay Energy For Elements Z=116 117 And 118 In Their Isotope chaIns LocAtes At N=178 rAther Than 184.
	Blind channel estimation of MIMO-OFDM based on FDPM (EI CONFERENCE) 会议论文 OAI收割 5th International Conference on Wireless Communications, Networking and Mobile Computing, WiCOM 2009, September 24, 2009 - September 26, 2009, Beijing, China Gang W.; Ming Z.; Hua C. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 Subspace based methods have been widely discussed in multichannel estimation including MIMO-OFDM system. However direct subspace methods suffer from heavy computation complexity y of O(N3). In this paper a new subspace tracking technique called Fast Data Projection Method (FDPM) is proposed for adaptively tracking the noise subspace. The new algorithm has low complexity of O(NL) and is the only numerically stable low complexity algorithm for tracking subspaces corresponding to the smallest singular values. Simulation results show that the proposed scheme has similar performance to the original. 2009 IEEE.
	Design of an improved data signal timing for an amorphous silicon active-matrix organic LED display (EI CONFERENCE) 会议论文 OAI收割 ICO20: Display Devices and Systems, August 21, 2005 - August 26, 2005, Changchun, China 作者: Zhang Z.-W. 收藏 \| 浏览/下载：32/0 \| 提交时间：2013/03/25 The most critical issue in the design of an active matrix organic light emitting diode (AM-OLED) display pixel is the pixel to the pixel luminance uniformity. By substituting four-thin film transistor (TFT) pixel circuit for two-TFT pixel circuit the luminous uniformity has great improved but it requires more components than the two-TFT pixel circuit. There are some barriers needed to resolve to utilize hydrogenated amorphous silicon transistor to lit OLED such as low field effect mobility low output current and threshold voltage shift. In this article a two-a-Si:H TFT pixel circuit was designed which consisted of one named switching TFT and the other named driving TFT. The driving TFT gate line structure modified and a data signal timing improved were reported. The modified driving TFT can provide enough current about 30 microampere to lit OLED and the novel data signal timing can provide a constant current to OLED by restraining the driving TFT threshold voltage variation. In the novel data signal timing the control signals to the driving TFT gate include a data signal and a reverse data signal. The signals alteration is performed either at a frame rate or at a line rate. By experiments the driving TFT output current value is plotted as a function of the time in different reversed voltage value. When the magnitude of the positive data signal and the negative data signal is equal the variety of Vth is smallest about 1.28V after a fixed stressing time of 1.33104min which shows the novel data signal timing can improved the driving TFT output-input current stability.
