Network pruning has a significant role in reducing network parameters and accelerating the inference time of the network. Some existing methods prune the network based on the frequency of the data, and finally obtain a sub-network with high accuracy. However, according to our experimental analysis, different frequencies of information in the data contribute differently to the accuracy of the model, and using this information directly for pruning without making a selection will lead to incorrect results. We believe that pruning should retain the convolutional kernels in the network that process important information, while those kernels that process unimportant information should be removed. In this paper, we first investigate the meaning of each frequency band information in the spectrum and their contribution to the prediction accuracy of the network,and according to these results, we propose a new pruning method based on frequency response(PFR). Our PFR finds and removes the convolutional kernels in the network that specialize in processing unimportant information, resulting in a compact neural network model. PFR obtains significant experimental results on different datasets, for example, a 56.0% raduction of float points operations(FLOPs) on Res Net-50 and only 0.37% of Top-1 accuracy degradation on the Image Net dataset.

Hepatic ischemia-reperfusion injury（HIRI） is characterized by mitochondrial dysfunction and oxidative stress. Monitoring mitochondrial hydrogen peroxide（mtH2O2） levels in real-time through super-resolution imaging is crucial for elucidating its distribution in live cells and its mechanism of action during HIRI. However, low-background fluorogenic probes have been overlooked in the context of super-resolution imaging. In this study, we developed a low-background fluorogenic probe（MitoWG） with the potential for super-resolution morphology-correlated mitochondrial identification to track the fluctuates of mtH2O2in HIRI. Activation of the desirable fluorescence properties of the probe by mtH2O2was confirmed using structural illumination microscopy（SIM）, enabling high-quality mitochondrial imaging with exceptional specificity and *** in mtH2O2levels were successfully observed in both cellular and rat models of HIRI. Furthermore, we associated the decline in mitochondrial redox homeostasis with accelerated mtH2O2production during HIRI, which triggered mitophagy deficiency and led to cell death. In conclusion, Mito-WG possesses excellent photophysical and low-background properties for SIM imaging, making it a promising tool for mtH2O2tracking in HIRI research and clinical diagnosis.

松滋河是连通长江与洞庭湖的主要通道。自1950s以来,随着下荆江系统裁弯及葛洲坝、三峡等水利工程相继建成,松滋河分流量呈现阶段性减少。基于系列水文和河道原型观测资料,分析了三峡水库蓄水后松滋口分流变化特征及其影响因素。结果表明:①三峡水库蓄水后,松滋口年分流比基本稳定在7%左右,没有明显趋势性变化;②当枝城站出现>25000 m 3/s流量时,蓄水后松滋口分流能力明显提升,特别是蓄水后前10 a;③三峡水库主汛期洪水调度影响较小,而汛末蓄水对口门分流产生消极影响;④荆江干流河床冲刷降低了口门处中枯水位,对松滋口分流产生不利影响;⑤芦家河浅滩航道整治工程实施在一定程度上对维持口门段中枯水位发挥了关键作用,口门河段河道采砂在一定时段改善了口门进流条件。
