High-altitude hypoxia (HH) significantly affects mammalian physiological functions, especially sleep rhythms, anxiety-like behavior, and neuroinflammation. In this study, adult male Sprague-Dawley rats were randomly assigned to five groups: Control, HH, HH with low-dose dexmedetomidine (Dex), HH with high-dose Dex, and Control with Dex. Rats were exposed to a simulated 6000-meter altitude for 7 days. Behavioral tests, enzyme-l...

With the growth of global trade, port shipping is becoming more and more important. In this paper, an analysis of a ship’s inbound and outbound track characteristics is conducted using the OD–Hausdorff distance. The accuracy and efficiency of trajectory data analysis have been enhanced through clustering analysis. Trajectories are arranged in a time sequence, and representative port segments are selected. An improved OD–Hausdo...
