Intestinal peroxisome proliferator‐activated receptor α‐fatty acid‐binding protein 1 axis modulates nonalcoholic steatohepatitis

open access: yesHepatology, EarlyView., 2022
Abstract Background and Aims Peroxisome proliferator‐activated receptor α (PPARα) regulates fatty acid transport and catabolism in liver. However, the role of intestinal PPARα in lipid homeostasis is largely unknown. Here, intestinal PPARα was examined for its modulation of obesity and NASH. Approach and Results Intestinal PPARα was activated and fatty

Continuous quasi-ordered weighted geometric operator and its application to group decision making(连续拟有序加权几何算子及其群决策应用)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
将拟有序加权几何算子(QOWG)推广至连续区间数上,提出了连续QOWG算子(CQOWG),探讨了其特殊情况和相关性质.其次,定义了 CQOWG算子的orness测度,研究了 orness测度的性质.然后,定义了加权连续QOWG算子(WCQOWG)、有序加权连续QOWG算子(OWCQOWG)以及组合连续QOWG算子(CCQOWG),并讨论了它们的性质.最后,提出了基于连续QOWG算子的多属性群决策方法,并通过决策实例说明其可行性与有效性.

改进YOLOv5的闪电哨声波轻量化自动检测模型

open access: yesKongjian kexue xuebao
提出一种改进YOLOv5(You-Only-Look-Once version 5)检测模型YOLOv5-Upgraded. 为了更快定位真实边框, 该模型将损失函数CIoU (Complete IoU)替换为SIoU(Scylla IoU); 同时为了避免网络训练过程中梯度消失、梯度爆炸以及神经元坏死等现象, 将激活函数SiLU(Sigmoid-weighted Linear Unit)替换为具有更好梯度流的Mish; 在主干网络中插入注意力 (Coordinate Attention, CA)机制,
