膝骨关节炎(knee osteoarthritis,KOA)是中老年人群常见的慢性退行性骨关节疾患,多以关节疼痛、活动受限为主要症状,常伴有关节肿胀、畸形等。膝关节肿胀限制关节活动,加重疼痛,影响患者的生活质量及身心健康。KOA肿胀原因总结为软骨与滑膜炎症、血管微循环异常、淋巴循环障碍、膝关节力学平衡失稳等。西医保守治疗主要是非甾体类抗炎药内服外用,关节灌注糖皮质激素治疗,然而患者易反复出现症状。中医药发展历史悠久,疗法多样,文献研究发现针灸、推拿、中药内服外用均有减轻KOA肿胀的效果,总结其治疗机制为降低炎症水平、促进循环代谢、抑制细胞外基质降解、调控软骨细胞增殖与凋亡等方面。该文将从KOA肿胀原因、现代医学消肿疗法、中医药消肿机制及主要调控通路进行综述,并总结目前研究热点,探讨未来研究方向。

养殖环境中饲料投放、水流变化等刺激源导致鱼类声音分辨难,使行为识别准确率不高,为解决上述问题,提出基于Mel声谱图(Mel spectrogram)与改进SEResNet的鱼类行为识别模型TAP-SEResNet。首先针对鱼类行为声音频率波动大、特征差异小,造成特征提取难的问题,采用高分辨率、特征表示较好的Mel声谱图以捕捉鱼类声音的频谱特征。其次针对鱼类声音特征关键信息易丢失的难题,提出在SEResNet模型中融合时序聚合池化层(Temporal Aggregated Pooling,TAP),提取池化区域的最大值和平均值,保留鱼类行为更多细粒度声音特征,提高识别准确率。为验证所提模型的有效性,分别设计了消融试验和模型性能对比试验,试验结果显示:TAP-SEResNet相比SEResNet在不降低检测速度的条件下准确率提升了3.23%;相比PANNS-CNN14、ECAPA-TDNN及MFCC+ResNet等先进声音识别模型,TAP-SEResNet在准确率上分别提升了5.32%、2.80%和1.64%。所提模型有助于养殖过程中对鱼类行为实现精准监测,对精准养殖具有重要的推动作用。

Bimagnetic metal constructed core-shell structure of Fe@Co nanowires for multi-band microwave absorption

引用

Progress in Natural Science:Materials International 2024年第02期34卷 354-361页

作者： Ping-an yang Rui Cai Haibo Ruan Nanqing Zhang Xin Huang Rui Li yuxin Zhang Yi Lu Zhihao Zhou School of Automation Chongqing University of Posts and Telecommunications Chongqing Key Laboratory of Materials Surface & Interface Science Chongqing University of Arts and Sciences College of Engineering and Technology Zunyi Normal College College of Material Science and Engineering Chongqing University

Controlled fabrication of materials by surface modification techniques has been a hot research topic. In this paper,one-dimensional(1D) core-shell structure Fe@Co nanowires(NWs) were successfully prepared by anchoring 0-dimensional(0D) Co nanoparticles on 1D Fe NWs based on the in situ reduction method. The electromagnetic parameters of the specimens at a filler mass fraction of 25 wt% were tested and the microwave loss mechanism was deeply analyzed. Binary magnetic metals in a core-shell structure have excellent multi-band microwave absorption capability(S-band, X-band and Ku-band). This is due to the heterogeneous interface and magnetic coupling effects tuning the dielectric and magnetic loss. This study offers a workable plan for creating effective multi-band magnetic metal-based microwave absorbers.
