Implantable Ionic Memristors Based on Natural Polymer Heterojunctions

Advanced Functional Materials, EarlyView.
We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

Abnormal amplitude of low-frequency fluctuations and functional connectivity in patients with primary dysmenorrhea

Frontiers in Integrative Neuroscience
ObjectiveThis study utilized resting-state functional magnetic resonance imaging (rs-fMRI) to investigate changes in the spontaneous activity of the default mode network (DMN) in patients with primary dysmenorrhea (PD) through amplitude of low-frequency fluctuation (ALFF) and functional connectivity (FC) analyses, aiming to explore their relationship ...

The Changes of Amplitude of Low-Frequency Fluctuation in the Acute Phase Patients with Concussion

Asian Case Reports in Emergency Medicine, 2015
目的：探讨伴有认知功能改变的脑震荡急性期患者功能磁共振低频振幅(ALFF)变化与其临床症状之间的关系。方法：采用静息态血氧水平依赖功能磁共振成像(BOLD-fMRI)及其低频振幅(ALFF)计算法，对急性期伴有认知功能改变的脑震荡患者在静息状态下获得相关资料进行分析。研究组为脑震荡成年患者10人；对照组为健康成年志愿者10人。研究组10人均在伤后72小时内完成BOLD-fMRI检查。两组均采用GE公司制造MR750 3.0T磁共振成像系统，在静息态下采集BOLD-fMRI成像数据。结果：与对照组比较，研究组在边缘叶、扣带回、楔前叶、左侧颞上回、颞中回、右侧额上回等脑区表现为ALFF值升高，临床上出现记忆能力、语言表达、情绪反应等认知功能改变。结论：脑震荡急性期患者认知功能异常，可能与边缘叶、扣带回 ...
