目的:解析成年C57BL/6J雌雄小鼠中下丘脑防御相关脑区的细胞结构基础及其性别差异特征。方法:利用荧光原位杂交技术分别标记Ⅱ型囊泡膜谷氨酸转运体(Vglut2)以及谷氨酸脱羧酶2(Gad2),从而实现特异性标记下丘脑多个防御相关亚区的谷氨酸能与γ-氨基丁酸(GABA)能神经元。利用自动计数软件Imaris,分析雌雄小鼠下丘脑防御系统的特定细胞类型的空间分布特征、相对比例与性别差异特征。结果:下丘脑亚区均表达谷氨酸能与GABA能神经元。其中,下丘脑腹内侧核、下丘脑外侧区前部主要表达谷氨酸能神经元,而下丘脑前区、下丘脑外侧区中后部、下丘脑背内侧核、下丘脑穹隆周围核以及未定带主要表达GABA能神经元。另外,通过对比各核团内不同亚区的表达特征,发现下丘脑前区中央部与未定带尾部表达更多的谷氨酸能神经元,而下丘脑外侧区中后部、下丘脑背内侧核腹侧部则表达更多的GABA能神经元。以上各个脑区的不同类型神经元的数量均未表现出性别差异。结论:下丘脑防御系统脑区的谷氨酸能与GABA能神经元的表达具有较高的区域特异性且未表现出性别差异。

Earthquake Engineering and Engineering Vibration 2010年第1期9卷 141-146页

作者： Yang Zhidong,huang Qitao~(++),Han Junwei~§and Li hongren~§National Key Laboratory of Robots Technique and System,Harbin Institute of Technology,Harbin 150080,China PhD Candidate ~++ PhD ~§Professor National Key Laboratory of Robots Technique and System Harbin Institute of Technology Harbin China

Random vibration control is aimed at reproducing the power spectral density （PSD） at specified control points. The classical frequency-spectrum equalization algorithm needs to compute the average of the multiple frequency response functions （FRFs）, which lengthens the control loop time in the equalization process. Likewise, the feedback control algorithm has a very slow convergence rate due to the small value of the feedback gain parameter to ensure stability of the system. To overcome these limitations, an adaptive inverse control of random vibrations based on the filtered-X least mean-square （LMS） algorithm is proposed. Furthermore, according to the description and iteration characteristics of random vibration tests in the frequency domain, the frequency domain LMS algorithm is adopted to refine the inverse characteristics of the FRF instead of the traditional time domain LMS algorithm. This inverse characteristic, which is called the impedance function of the system under control, is used to update the drive PSD directly. The test results indicated that in addition to successfully avoiding the instability problem that occurs during the iteration process, the adaptive control strategy minimizes the amount of time needed to obtain a short control loop and achieve equalization.
