Reduction of bridge dynamic amplification through adjustment of vehicle suspension damping [PDF]
, 2007 This paper presents a novel approach to the reduction of short-span bridge dynamic responses to heavy vehicle crossing events. The reductions are achieved through adjustment of the vehicle suspension damping coefficient just before the crossing.

Characteristic dynamic traffic load effects in bridges [PDF]
, 2009 When formulating an approach to assess bridge traffic loading with allowance for Vehicle-Bridge Interaction (VBI), a trade-off is necessary between the limited accuracy and computational demands of numerical models and the limited time periods for which ...

Numerical study of pedestrian suspension bridge with innovative composite deck
Heliyon, 2020 The increasing trend of using light and slender deck in pedestrian bridge has raised the issue of instability under pedestrian movement. The suspension pedestrian bridges are more vulnerable as lateral vibration often occurred in such type of bridges ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
