Exploring the topological graph encoding implementation of integer grids(探索整数格的拓扑图编码实现)

open access: yesZhejiang Daxue xuebao. Lixue ban
In the post quantum era, lattice cryptography is featured as an interdisciplinary and diversified research method, and is most likely to become post quantum cryptography. The graphic lattice in topological coding is the product of interdisciplinary study.

基于噪声敏感先验的改进VMD惯导异构信号降噪

open access: yesZhendong Ceshi yu Zhenduan
针对煤矿锚杆钻车姿态估计中惯性导航的多源噪声,提出一种基于噪声敏感先验的改进变分模态分解(variational mode decomposition,简称VMD)惯导异构信号降噪方法。首先,利用加速度和角速度时频域参数特性变化,探究捷联惯导异构信号的噪声敏感差异和多源噪声作用规律;其次,根据异构信号噪声敏感先验和最大峭度变化趋势,构建双分解层,并通过能量波动模型监测在不同分解层下模态分量的能量变化,避免参数固定造成的过分解和欠分解问题,实现对惯导异构信号同步VMD分解;然后,根据皮尔逊相关系数 ...

MiRNA调控脑缺血/再灌注诱导的自噬信号通路研究进展

open access: yesZhongshan Daxue xuebao. Yixue kexue ban
脑卒中时缺血缺氧致脑组织功能损伤,且缺血后脑组织再恢复血液供应时,大量自由基、钙超载等引起脑缺血/再灌注损伤,进一步加重病情。自噬是一种维持细胞内环境稳态的自我保护机制,但过度自噬引起脑组织损伤。MiRNA为小的内源性非编码RNA分子,通过与其靶基因mRNA的3’ -UTR中的互补序列结合,导致翻译抑制或mRNA降解,从基因水平上调控多种生理活动。MiRNA不仅直接作用于自噬相关蛋白,还可通过多种信号通路,参与缺血/再灌注诱导的自噬调控。但关于miRNA调控脑缺血 ...
