为了识别并定量刺激诱导的ROS从有益作用转变为有害作用的阈值，中国科学院生物物理研究所陈畅课题组研究人员以秀丽隐杆线虫为模型，用不同浓度百草枯（PQ）诱导的氧化应激对线虫寿命的不同影响来描述和定量阈值。研究发现，存在一个PQ的节点浓度，低于这个浓度的PQ诱导产生的氧化应激能延长寿命，而超过这个浓度的PQ诱导产生的氧化应激对线虫的生存是有害的。

基于DWT的抗RST攻击鲁棒性数字水印
鲁棒性 RST变换 不变矩
2009/11/26
针对现有数字图像水印方法对几何变换攻击鲁棒性不足的问题，提出一种基于离散小波域的抗几何攻击数字水印方法，对图像进行离散小波变换，在其低频逼近子图嵌入水印，通过检测其不变矩实现数字水印检测。由于所选不变矩具有旋转、平移、尺度变换不变特征，因此该方法对几何变换攻击具有鲁棒性。仿真实验结果表明，该方法对普通加噪、滤波、JPEG压缩攻击以及旋转、缩放、平移等几何攻击均具有较好的鲁棒性。
