研究了圆环型波导依照蜂窝结构排列的声子晶体系统中的拓扑相变.利用晶格结构的点群对称性实现赝自旋,并在圆环中引入旋转气流来打破时间反演对称性.通过紧束缚近似模型计算的解析结果表明,没有引入气流时,调节几何参数,系统存在普通绝缘体和量子自旋霍尔效应绝缘体两个相;引入气流后,可以实现新的时间反演对称性破缺的量子自旋霍尔效应相,而增大气流强度,则可以实现量子反常霍尔效应相.这三个拓扑相可以通过自旋陈数来分类.通过有限元软件模拟了多个系统中边界态的传播,发现不同于量子自旋霍尔效应相,量子反常霍尔相系统的表面只支持一种自旋的边界态,并且它无需时间反演对称性保护.

BACKGROUND Ganglioneuroma(GN) is a rare and benign tumor that originates from autonomic nervous system ganglion cells. The most frequently involved sites are the posterior mediastinum, the abdominal cavity, and the retroperitoneal space. It rarely occurs in the cervical area, compressing the spinal cord. Neurofibromatosis type 1(NF-1) is an autosomal dominant inheritance disorder, whose prevalence rate approximates one per *** SUMMARY We report an extremely rare case of bilateral and symmetric dumbbell GNs of the cervical spine with NF-1. A 27-year-old man with NF-1 presented with a one-year history of gradually progressive right upper extremity weakness and numbness in both hands. Magnetic resonance imaging showed bilateral and symmetric dumbbell lesions at the C1-C2 levels compressing the spinal cord. We performed total resection of bilateral tumors, and the postoperative histopathological diagnosis of the resected mass was GN. After operation, the preoperative symptoms were gradually relieved without complications. To our knowledge,this is the sixth report of cervical bilateral dumbbell *** In some cases, cervical bilateral dumbbell GNs could be associated with *** exact diagnosis cannot be obtained before operation, and pathological outcome is the current gold standard. Surgical resection is the most effective option, and disease outcome is generally good after treatment.

The magnetostriction, magnetization, and spin reorientation properties in Pr(Ga_(x)Fe_(1-x))_(1.9) alloys have been investigated by high-precision x-ray diffraction(XRD) step scanning, magnetization, and Mossbauer spectra measurements. Ga substitution reduces the magnetostriction(λ_(||)) with magnetic field H ≥ 8 kOe(1 Oe = 1.33322×10^(2) Pa), but it also increases the λ|| value when H ≤ 8 kOe at 5 K. Spin-reorientations(SR) are observed in all the alloys investigated, as determined by the step scanned XRD, Mossbauer spectra, and the abnormal temperature dependence of magnetization. An increase of the spin reorientation temperature(T_(SR)) due to Ga substitution is found in the phase diagram, which is different from the decrease one in many R(T_(x) Fe_(1-x))_(1.9)(T = Co, Al, Mn) alloys. The present work provides a method to control the easy magnetization direction(EMD) or T_(SR) for developing an anisotropic compensation system.

为了解决无损卡尔曼滤波(UKF)算法计算量随着状态维数增加而急剧增大的问题,将非线性初始对准滤波模型分解为线性与非线性两部分,并提出一种基于此模型分解的KF/UKF组合滤波算法,设计了该组合算法的滤波步骤,理论上证明了该组合算法仍为最小均方误差估计意义下的最优估计。通过仿真实验比较了KF/UKF组合算法和UKF算法的滤波效果,结果表明,基于KF/UKF组合算法的运算速度优于UKF算法。

AIM To investigate the pathophysiologic basis of syndrome of Liver Qi stagnation and parameters for clinical differentiation. METHODS Plasma L ENK, AVP, ANP and serum gastrin were determined by RIA in 84 patients with neurasthenia, mastodynia, chronic gastritis, and chronic cholecystitis presenting the same syndrome of Liver Qi stagnation in traditional Chinese medicine (TCM). Healthy subjects served as controls in comparison with patients having the same syndrome but with different diseases. RESULTS Among the patients with Liver Qi stagnation, the plasma L ENK, ANP and gastrin levels were 38 83ng/L ± 6 32ng/L , 104 11ng/L ± 29 01ng/L and 32 20ng/L ± 6 68ng/L , being significantly lower than those in the healthy controls ( t =3 34, 6 17, 4 48; P 0 05. CONCLUSION The syndrome of Liver Qi stagnation is closely related to the emotional modulatory abnormality of the brain, with decrease of plasma L ENK, ANP and gastrin, and increase of plasma AVP as the important pathophysiologic basis.
