Predicting Critical Speed of Railway Tracks Using Artificial Intelligence Algorithms
Vibration, 2023 Motivated by concerns regarding safety and maintenance, the operational speed of a railway line must remain significantly below the critical speed associated with the track–ground system. Given the large number of track sections within a railway corridor

Critical dislocation speed in helium-4 crystals [PDF]
, 2013 Our experiments show that in $^4$He crystals, the binding of $^3$He impurities to dislocations does not necessarily imply their pinning. Indeed, in these crystals, there are two different regimes of the motion of dislocations when impurities bind to them.

Study on the Vibration Characteristics of Yaw Gear System for Large-Capacity Offshore Wind Turbine
한국해양공학회지, 2023 Vibration and noise must be considered to maximize the efficiency of a yaw system and reduce the fatigue load acting on a wind turbine. This study investigated a method for analyzing yaw-system vibration based on the change in the load-duration ...

Observing Air Showers from Cosmic Superluminal Particles [PDF]
, 1997 The Poincar\'e relativity principle has been tested at low energy with great accuracy, but its extrapolation to very high-energy phenomena is much less well established. Lorentz symmetry can be broken at Planck scale due to the renormalization of gravity
