基于局部区域的移动性管理策略

基于用户呼叫和移动的局域性提出了一种基于局部区域的多层结构位置管理策略，并对其代价和呼叫建立时间进行了分析，结果表明只要局部区域选择恰当，呼叫移动比稍高时该策略优于基本策略．     

A method for chromosome preparations from large fish specimens using in vitro short-term treatment with colchicine

This paper describes a new technique for preparing mitotic fish chromosomes using short-term in vitro treatment with colchicine. The results show that a large number of good quality metaphases (many suitable for chromosome banding) can be obtained by this technique, which requires an average of 1 h and 30 min for all steps. The procedure considerably reduces the time normally required for chromosome preparations in fish.This work was supported by grants FUNCUNESP, FAPESP and CNPq.The authors are grateful to Mr Renato Devidé for technical assistance.

均匀介质覆层导电椭圆柱电磁散射分析

本文采用 OSRC—GMT 研究了共焦均匀介质覆层导电椭圆柱的电磁散射特性。文中仅讨论了横磁(TM)波散射的情况、而横电(TE)波的情况可按同样方法分析。本中给出了用OSRC—GMT 方法求得的日标散射方向图的数值结果。数值计算表明,该方法求得的解与精确解有着良好的吻合。     

Super-high sensitivity systems for detection and spectral analysis of ultraweak photon emission from biological cell cells and tissues

Summary In this paper we summarize and discuss the modern technology and systems, studied and established by our research group, for performing the detection and special analysis incorporated with the super-high senstivity photon counting method for the study of ultraweak photon emission; for example, extra-weak bioluminescence and chemiluminescence from living cells and tissues, closely related to biochemical and biophysical processes and activities. An excellent sensitivity of the basic photon counting system, making it possible to achieve count rates in the very low range of one photoelectron per second to one per minute, allowed us to carry out in vivo as well as in vitro measurements, and analyses of ultraweak bioluminescence and chemiluminescence. Recent results concerning ultraweak photon emission from blood samples and organ homogenates of rats are presented and reviewed as one of the interesting and valuable applications of our modern technology for studying ultraweak cell and tissue radiation.
