We numerically investigate the first-passage time statistics of active particles in confined one- and two-dimensional geometries, subject to stochastic trapping and directional bias. The dynamics alternate between persistent ballistic runs, trapping phases with power-law distributed waiting times, and stochastic reorie...
Structured environments organize active-particle currents by coupling propulsion and orientational dynamics to geometry. Translationally periodic ratchets can produce a rotation-frequency-dependent drift across equivalent unit cells, but the locked position remains spatially degenerate. In this paper, we show that a ra...
Predicting aircraft landing gear responses under extreme conditions is important for condition monitoring and safety assessment. In oleo-pneumatic landing gear systems, the vertical load and strut stroke are intrinsically coupled through the shock absorber. The vertical load exhibits bimodal or multimodal peaks with la...
