Synthesis and characterization of amorphous Al-Mg-B prepared by various deposition temperatures

引用

Rare Metals 2013年第2期32卷 159-164页

作者： Wen-Chao Qu ai-min wu Yi-Zhen Bai Xin Jiang Key Laboratory of Materials Modification by Laser Ion and Electron BeamsMinistry of EducationDalian University of Technology School of Materials Science and Engineering Dalian University of Technology School of Physics and Optoelectronic Technology Dalian University of Technology Institute of Materials Engineering University of Siegen

Amorphous A1MgB thin films were synthesized via a combinatorial sputtering approach. The properties of aiMgB films with the varying deposition temperature was investigated. The deposition temperature was found to dominate the hardness of the amorphous asdeposited film. The hardness increases with increasing deposition tempera ture and may even exceed that of crystalline A1MgB14 mate rial. The high hardness may be attributed to the existence of randomly distributed B 12 icosahedra structure. Therefore, the thin film that was deposited on cemented carbide shows well cutting performances in turning Ti alloy bar. At the same time, an appropriate method of pretreatment is the key to ensure the coating tool with the excellent adhesion by impact fracture test.

KNAT7 positively regulates xylan biosynthesis by directly activating IRX9 expression in Arabidopsis

Xylan is the major plant hemicellulosic poly- saccharide in the secondary cell wall. The transcription factor KNOTTED-LIKE HOMEOBOX OF ARABIDOPSIS THALIANA 7 （KNAT7） regulates secondary cell wall biosynthesis, but its exact role in regulating xylan biosynthesis remains unclear. Using transactivation analyses, we demonstrate that KNAT7 activates the promoters of the xylan biosynthetic genes, IRREGULAR XYLEM 9 （IRX9）, IRX10, IRREGULAR XYLEM 14-LIKE （IRX14L）, and FRAGILE FIBER 8 （FRAS）. The knat7 T-DNA insertion mutants have thinner vessel element walls and xylary fibers, and thicker interfascicular fiber walls in inflorescence stems, relative to wild-type （WT）. KNAT7 over- expression plants exhibited opposite effects. Glycosyl linkage and sugar composition analyses revealed lower xylan levels in knat7 inflorescence stems, relative to WT; a finding supported by labeling of inflorescence walls with xylan-specific antibodies. The knat7 loss-of-function mutants had lower transcript levels of the xylan biosynthetic genes IRX9, IRX10, and FRAS, whereas KNAT7 overexpression plants had higher mRNA levels for IRX9, IRX10, IRX14L, and FRA8. Electrophoretic mobility shift assays indicated that KNAT7 binds to the IRX9 promoter. These results support the hypothesis that KNAT7 positively regulates xylan biosynthesis.

A model reduction approach for discrete-time linear time-variant systems with delayed inputs

引用

Science China(Information Sciences) 2024年第4期67卷 197-217页

作者： ai-Guo wu Guang-Ren DUAN Yu WANG Jie ZHANG School of Mechanical Engineering and Automation Harbin Institute of Technology(Shenzhen) HIT wuhu Robot Technology Research Institute Center for Control Science and Technology Southern University of Science and Technology

A model reduction approach is presented for discrete-time linear time-variant input-delayed systems. According to this proposed approach, a dynamical variable is constructed by taking advantage of the current state and historical information of input. It is revealed that the behavior of this dynamical variable is governed by a discrete-time linear delay-free system. It is worth noting that the presented variable transformation does not require the system matrix to be invertible. Based on the reduced delay-free models,stabilizing control laws can be easily obtained for the original delayed system. For the case with a single input delay, the constructed variable is an exact prediction for the future state, and thus the stabilizing control law could be designed by replacing the future state with its prediction. Finally, three discrete-time periodic systems with delayed input are employed to illustrate how to utilize the presented model reduction approaches.

We demonstrate a low-noise,high-gain,and large-dynamic-range photodetector(PD)based on a junction field-effect transistor(JFET)and a charge amplifier for the measurement of quantum noise in Bell-state detection(BSD).Particular photodiode junction capacitance allows the silicon N-channel JFET 2sk152 to be matched to the noise requirement for charge amplifier *** electronic noise of the PD is effectively suppressed and the signal-to-noise ratio(SNR)is up to 15 dB at the analysis frequency of 2.75 MHz for a coherent laser power of 50.08µ*** combining of the inductor and capacitance,the alternating current(AC)and direct current(DC)branches of the PD can operate linearly in a dynamic range from 25.06µW to 17.50 *** PD can completely meet the requirements of SNR and dynamic range for BSD in quantum optics experiments.
