Comment on Greenwood (2007): Solving the puzzle of structure/function relations in the aging brain?

Neuroimaging experiments have shown that prefrontal regions of the brain, which have the most age-related volume loss, are also the regions most likely to be more active in older adults than in younger adults. In an attempt to solve this puzzle, P. M. Greenwood (see record 2007-15625-001) has proposed a cascade that flows from age-related atrophy in the brain to changed processing strategies that result in plastic changes in regions adjacent and contralateral to the atrophic areas, culminating in greater functional activity. This hypothesis should stimulate research into these mechanisms and hopefully will ultimately inform researchers' ability to rehabilitate cognitive disorders in the elderly.

InP基应变补偿结构偏振不灵敏半导体光放大器制作的研究

为了制备偏振不灵敏的半导体光放大器(SOA)，将有源区设计为由4个压应变、3个张应变阱层及晶格匹配的垒层InGaAsP交替组合而成的应变补偿结构。器件做成带有倾角的扇形脊形波导结构，避免了常规制作SOA的复杂工艺。对样品3在80～125mA电流范围内，获得了偏振灵敏度≤0．6dB．最小可达0．1dB；较大的电流范围内FWHM值为40nm。     

一种基于bit位的运动补偿方法

本文讨论了等离子体显示屏所特有的在显示运动画面时出现的伪轮廓线现象，对产生的原因进行了分析并给出了软件模拟的结果。在此基础上，提出了一种基于bit位的运动补偿方法来改善运动图像的画面质量，同时根据人眼的视觉特征对补偿方法做了进一步的优化。最后对基于bit位的运动补偿方法进行了比较和验证，结果表明基于bit位的运动补偿方法可以基本消除运动画面的伪轮廓线现象。

An automatic torque ripple compensation system for direct drive motors

A serious problem in motion control is the occurrence of torque ripple. Since a direct drive (DD) motor with a magnet rotor uses a rare-earth magnet, the torque ripple is more serious than that of conventional servomotors. This paper presents an auto-compensation of torque ripple using a software-implemented torque observer. The frequency and amplitude of torque ripple can be obtained in the controller by using the estimated torque from an observer, and the autonomous generation of a compensating current component for a torque ripple is possible. The proposed algorithm has been verified by experiments.
