Immunohistochemical study of epithelioid hemangioendothelioma in the leg: a case report

Epithelioid hemangioendothelioma is a relatively rare lesion. Although its histogenesis has been well described, its immunohistochemical characteristics remain controversial. A case of epithelioid hemangioendothelioma of the soft tissue of the right leg in a 67-year-old Chinese woman is reported. Histologic findings of intracytoplasmic lumina in the tumor cells and positive immunostaining for vimentin, factor VIII-related antigen. CD34 and Ulex europaeus agglutinin 1 (UEA-1) were obtained, demonstrating differentiation of the tumor cells to endothelial cells, although staining for antibodies to cytokeratins AE1/AE3 and CAM5.2 was weak. CD34 as well as Factor VIII-related antigen is a useful marker of endothelial differentiation in this tumor. A review of the literature is also presented.

Closed-form solutions for one-dimensional inhomogeneous anisotropicmedium in a special case. I. Direct scattering problem

An analytical formulation is presented for the direct scattering problem of one-dimensional (1-D) inhomogeneous anisotropic medium in a special case. This method gives nonlinear differential equations for the reflection coefficients of the anisotropic medium. Applying the discontinuity condition of the dielectric parameters at the interface of the medium with free space, approximate closed-form solutions for the reflection coefficients are obtained. Numerical examples show the validity of the method

Closed form solution for the sensor registration problem using only position information

Sensors, mounted on the dexterous end of a robot, can be used for feedback control or calibration. When you mount a sensor on a robot it becomes necessary to find the pose (orientation and position) of the sensor relative to the robot. This is the sensor registration problem. Many researchers have provided closed-form solutions to the sensor registration problem; however, the published solutions apply only to sensors that can measure a complete pose (three positions and three orientations). Many sensors, however, can provide only position information; they cannot measure the orientation of an object. This article provides a closed-form solution to the sensor registration problem applicable when: (1) the sensor can provide only position information and (2) the robot can move along and rotate about straight lines. © 1994 John Wiley & Sons, Inc.     

变温长波碲镉汞光电导现象研究

报道了ｎ型Ｈｇ０．８Ｃｌ０．２Ｔｅ光电导体的变温材料参数与性能参数的对照关系，并讨论了材料的锭条参数与小芯片霍耳参数的差异，得到一组光电导的实验优化数据，实测小芯片载流子浓度ｎ≈１．８×１０＾１５ｃｍ＾－３，这与高性能器件实测值的倒推数值一致，这被解释为长江红外高背景辐射的结果。     

P偏振光双表面反射比的角谱及其应用

p-偏振光在镀膜平板基片两面的反射光强度比值的角谱是膜层参数(折射率、消光系数和厚度)的函数.实验表明通过角谱的测量和数值模拟是精确测量薄膜参数的新途径.基于此原理,还试制出掺Sb的SnO2溶胶凝胶薄膜的光化学气敏传感器.
