Semi-active suspension systems from research to mass-market – A review

Journal of Low Frequency Noise, Vibration and Active Control, 2021
It is well documented that active suspension systems offer substantial benefits in ride comfort, handling control over traditional passive systems. However, restrictive features such as the power required and costs make an active system impractical.

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Energy harvesting using semi-active nonlinear control

, 2013
This paper presents the application of semi-active control for power harvesting using an electromechanical energy harvester. Two semi-active control strategies are proposed in the form of a time-periodic damper and a nonlinear cubic damper.

Comparing the Performance of Using a Smart Damper in a Semi-Active ‎‎Suspension Instead of a Traditional Damper Using MATLAB/Simulink

International Journal of Applied Mechanics and Engineering
‎ Given the importance of comfort and safety in various driving circumstances, the suspension system emerges as the most ‎crucial component. Two different suspension systems, passive (PSS) and semi-active (SASS), are compared for effectiveness in ...
