本文关注非可视条件下的智能驾驶需求,利用毫米波雷达可全天候工作及受光照和天气影响较小的特性,实现路面可跨越障碍物的形位特征识别。本文以路面减速带为例,构建基于毫米波雷达的路面障碍物特征感知系统,将雷达天线平面朝向地面并与地面保持一定夹角,利用FFT-CZT两级处理结构对雷达中频数据进行频谱细化,获得较高精度的距离值。进一步通过分析雷达点云数据,将每帧数据中获取的最短目标距离值进行融合,得到路面减速带的二维可视化成像。最后,通过对可视化数据的分析,建立路面减速带几何模型,提出减速带特征参数计算方法。本文搭建了实车测试平台,采集了从0°到90°不同夹角数据,在45°夹角处得到减速带高度估计值平均绝对误差保持在4 mm以内,宽度估计值平均绝对误差为21 mm,验证了本文提出方法的有效性。

Different polarity polyphenol extracts from P. cerasifera fruits ameliorate non-alcoholic fatty liver disease via bile acid metabolism and gut microbiota

Food Science and Human Wellness 2025年

作者： Jiabao Ren Chunlin hao Helong Han Enpeng He Yanhong li Key Laboratory of Special Environment Biodiversity Application and Regulation in Xinjiang， College of life Sciences， Xinjiang Normal University Key Laboratory of Sports Human Sciences， Institute of Physical Education， Xinjiang Normal University

Non-alcoholic fatty liver disease (NAFLD) is a global metabolic disease caused by abnormal accumulation of lipids in the liver， for which effective therapeutic targets and drugs are scarce. P. cerasifera polyphenol extract (PPE) has been proven to be able to alleviate NAFLD via the “gut microbiota - bile acid” signaling pathway， but its active ingredients that exert anti-NAFLD effects are still unclear. In this study， PPE was separated according to different polarities， and the optimal components for exerting anti-NAFLD effects based on the “gut microbiota - bile acid” signaling pathway were explored. Different polarity polyphenol extracts from P. cerasifera， especially aqueous PPE (APPE) enhanced hepatic bile acid synthesis and alleviated liver injury in NAFLD mice. Meanwhile， APPE significantly reduced the levels of BSH-producing bacteria， in particular Bacteroidetes， and reduced the presence of endogenous FXR ligands (CDCA， LCA， and DCA) in the intestines of NAFLD mice， thereby inhibiting the ileal FXR-FGF15 axis. In addition， activation of the hepatic FXR-SHP axis by APPE also supported CYP7A1- and CYP27A1-mediated bile acid synthesis. The data suggested that APPE demonstrated a notable anti-NAFLD effect through the “gut microbiota - bile acid” signaling pathway， indicating the potential for isolating individual compound from APPE for the treatment of NAFLD.
