This paper proposes a better method for determining the fixed point'sneighborhood in which the system remain stable when subjected to a linear law. Thevalidity of this method is shown by a theorem on effective local control of nonlinear,chaotic dynamical system, with numerical confirmation. The ways of implementing theobtained theorem in practice are proposed.

In this paper. we use the improved closed-loop control method to realizethat the discrete chaotic system stabilizes to any arbitrarily chosen dynamics. We givethe strict proof as well as the general result of 2-dimensional system to show the feasibiltyof our method and criterion. Furthermore, the well-known Henon system is chosen foran example and the corresponding computer simulation results are given to support ourmethod.

Castleman disease is a rare disorder of the lymphoid system characterized by noncancerous growths that may develop in lymph node tissues throughout the body. Most often this occurs in the neck, mediastinum, and abdomen where lymph nodes aggregate. Here we describe a case of asymptomatic intrapulmonary Castleman disease adjacent to the left pulmonary hilum that mimicked central pulmonary malignancy in a 27-year-old man who underwent curative surgical removal of the mass.

Research on a single cell Multi-gap Resistive Plate Chamber (MRPC) was carried out for the Time Of Flight detector (TOF) R and D of the STAR experi- ment. The property of the single chamber was tested with the test beam facility T10 at CERN in Geneva. The MRPC was scanned with the test beam to get the efficiency and time resolution at different position of the active area. The HV plateau was also measured. The time resolution is 65 ps which satisfies the requirement of STAR. The working mechanism of the MRPC is also explained.

研究台风“启德”经过南海北部对南海深海海洋环境噪声的影响,表明台风导致的风速增减、降雨强弱以及形成的长波涌浪均会影响海洋环境噪声级的大小变化,海洋环境噪声显著受到台风的影响。相同风级下,台风期间海洋环境噪声级与风速的相关性明显好于非台风期间。分析测量的415 h海洋环境噪声数据与风速、波高的相关性,频率大于300 Hz时,海洋环境噪声级与风速的互相关系数大于0.5,达到中度相关;频率大于630 Hz时,互相关系数介于0.8和0.9之间,达到高度相关;频率大于300 Hz时,海洋环境噪声级与风速的相关性好于海洋环境噪声级与波高的相关性。南海海洋环境噪声10~20 Hz的次声频与风速的相关性差,是因为南海航运繁忙,该频段的海洋环境噪声会受到航船噪声的影响,即使台风期间也不例外。
