Dynamic of Friction Coupling Independently Rotating Wheels for High Speed

Shock and Vibration, 2017
A new lateral coupling structure with independently rotating wheels (IRW) is proposed, and longitudinal creepage is obtained by replacing the gear pair with the friction pair to synchronize the rotation speed of left and right wheels.

A study of lateral-force estimation equation focusing on moment of a train bogie

Nihon Kikai Gakkai ronbunshu, 2016
When railway vehicles pass through a sharp curve, yaw moment is generated at the bogie. This condition affects the increase of the lateral force of the outside wheel of the front axle of the leading bogie, which is important factor for assessing the ...

Direct evidence implicating the asymmetrical dimethylarginine (ADMA)‐dimethylarginine dimethylaminohydrolase 1 (DDAH1) pathway in cerebrovascular dysfunction and stroke pathogenesis in mice

British Journal of Pharmacology, Volume 183, Issue 21, Page 6422-6443, November 2026.
Abstract Background and Purpose Asymmetrical dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS), whereas dimethylaminohydrolase 1 (DDAH1) is primarily responsible for its metabolism. However, the roles of DDAH1 in cerebrovascular regulation are poorly understood. Furthermore, despite evidence that elevated ADMA levels are

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, Volume 27, Issue 5, Page 7026-7047, October 2026.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule
