针对将形状指数(SI)应用于三维图像时缺乏对应的推广形式,常通过计算三维图像的3个截面的SI来组合表达,导致在肠道肿瘤检测等应用中造成了大量的误检的问题,研究了三维情形SI的推广.首先选取球坐标系表达的单位球面以消除灰度变化尺度的影响;然后分析了球面的6个等价区域,并选取其一作为灰度变化的表征区域;由于SI原有的表达式不利于推广到三维空间,因此推导了一种等价的表达式,并通过分析此表达式在三维情形的推广,得到了描述三维图像局部灰度变化的指标——密度指数(DI).通过研究DI所表征区域的几何特性,得到了一条具有重要性质的曲线——逆Z线,并分析了其上典型特征点所对应的灰度变化模式.仿真实验结果表明,对于肠道肿瘤检测的典型情况,使用DI检测的误检率明显低于SI.

Small and thin mesa structures of intrinsic Josephson junctions 1- 2μm on a side and 1.5-7.5 nm in thickness are fabricated from single crystals of Bi2-xPbxSr2CaCu2O8＋δ with a nominal Pb content x from 0.2 to 0.5. The Josephson critical current density jc is found to be pronouncedly large, ranging from 10 to 50 kA/cm^2. Switching current probability measurements for these mesa samples show an indication of a crossover to the macroscopic quantum tunneling region.

There are four steps in the interaction between intestinal microbes and mucosal inflammation in genetically predisposed individuals from the viewpoints of basic and clinical aspects of inflammatory bowel disease （IBD）. The first step is an interaction between intestinal microbes or their components and intestinal epithelial cells via receptors, the second step an interaction between macrophages and dendritic cells and mucosal lymphocytes, the third step an interaction between lymphocytes and vascular endothelial cells, and the fourth step an interaction between lymphocytes and granulocytes producing proinflammatory cytokines or free radicals and mucosal damage and repair. Recent therapeutic approaches for IBD aim to block these four steps in the intestinal inflammation of patients with IBD.

Recently, linear motors can have high speed control, high acceleration-deceleration. So linear motors are widely used in industrial applications such as precision machine tools. In our laboratory focusing on transport system, we propose parallel synchronous drive of used the PM-LSM （permanent magnet linear synchronous motor）. It can pass luggage without having to stop the working. When you establish ＂parallel synchronous drive＂, a motor follows the other motor. In our laboratory, one of the motors is called ＂master motor＂ and the other motor called ＂slave motor＂. The master motor＇s speed and position pass slave motor then establish parallel synchronous drive. Therefore, slave motor requires high-responsive and precision that follows the master motor. This paper focuses on the control of the slave motor.

Platelet rich plasma (PRP) contains a high concentration of thrombocytes and the a granules of platelets contain platelet released growth factors. The usefulness of PRP for regeneration of bone and soft tissues has been reported previously. We firstly reported the efficacy of PRP prepared using the Magellan Autologous Platelet Separator System for intractable skin ulcers such as diabetic and venous ulcers. The system consists of a microprocessor controlled centrifuge, syringe pumps, and necessary single use processing components. No complications occurred in any patients and the wounds achieved complete epithelialization. Our results have shown the efficiency of platelet rich plasma for the treatment of intractable skin ulcers.

We describe a case of infiltrating angiolipoma of the thoracic wall, which is an extremely unusual site for this tumor. Infiltrative angiolipoma is a rare benign soft tissue tumor that commonly affects the extremities and the trunk. This is the first report of infiltrative angiolipoma that affects this site. Magnetic resonance imaging (MRI) revealed a high intensity signal on T2-weighted images and contrast enhanced images showed moderate enhancement effect that mimicked tumors of neurogenic or vascular origin. Angiolipoma should be included in a differential diagnosis of the thoracic wall tumor with T2 high intensity signal and contrast enhancement that is not typical shape and signal for neurogenic tumor or hemangioma.
