Leigh综合征(Leigh Syndrome,LS)又称亚急性坏死性脑脊髓病(SNEM),是一种罕见的、由遗传基因缺陷导致的以脑和肌肉受累为主的线粒体疾病。其特征性表现为肌无力、慢性进行性眼外肌麻痹、智能障碍、共济失调、发作性肌阵挛、视神经病变等。典型影像学MRI表现为基底节区及脑干对称性异常信号。据目前报道,约48%至80%的患者在1岁以内发病[1,2],幼儿期发病者少见。另外,近年国外研究显示,线粒体疾病患者中仅约7-10%可检测出线粒体DNA(mitochondrial DNA,mtDNA)变异[

行星齿轮箱出现早期故障时,由于工业环境的背景噪声干扰和故障冲击在复杂传递路径中衰减,其微弱故障特征难以有效提取和识别。针对此问题,提出了稀疏引导的改进经验小波变换(improved empirical wavelet transform,简称IEWT)结合多点最优最小熵解卷积(multipoint optimal minimum entropy deconvolution adjusted,简称MOMEDA)的微弱故障特征提取方法。首先,提出了一种新的故障综合指标(fault composite ...
