This paper focused on the motion control of an underwater vehicle installed on a linear guide system, which is driven by two electric winches with wire ropes. The vehicle is subject to complex nonlinear time-varying disturbances and actuator input saturation effects during motion. A coupled dynamic model, incorporating an underwater vehicle, winches, and wire ropes, was established. Particular attention was paid to the nonline...

The Stat (signal transducer and activator of transcription) gene family plays a vital role in regulating immunity and the processes of cellular proliferation, differentiation, and apoptosis across diverse organisms. Although the functions of Stat genes in immunity have been extensively documented in many mammals, limited data are available for reptiles. We used phylogenetic analysis to identify eight putative members of the St...

The frequency and intensity of heatwaves over southwestern China during spring and early summer have been increased significantly during 1980–2022. Until now, the physical mechanisms for these changes in heatwaves remain unclear. Here, we show that these increases in heatwaves can be attributed to the changes in both local soil moisture–temperature coupling processes and teleconnection patterns across Eurasia. On the one hand,...
