Design and performance evaluation of a novel fractional order PID control strategy for vehicle semi-active suspension

Advances in Mechanical Engineering
The performance of a semi-active suspension depends on the quality of the control algorithm. Considering the limitations of conventional PID controllers within intricate nonlinear systems, such as imprecise parameter tuning and performance deterioration,

Optimal Sliding Mode Control for an Active Suspension System Based on a Genetic Algorithm

Algorithms, 2018
In order to improve the dynamic quality of traditional sliding mode control for an active suspension system, an optimal sliding mode control (OSMC) based on a genetic algorithm (GA) is proposed.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

RESEARCH ON ACTIVE CONTROL OF VARIABLE MASS SEAT SUSPENSION USING PD CONTROL

Jixie qiangdu
Aiming at the system non-linearity caused by the change of load mass of seat suspension and the effective control of seat vibration, an active control system of variable mass seat suspension based on the proportional-derivative (PD) control was proposed.

Global Chassis Control: Integration Synergy of Brake and Suspension Control for Active Safety [PDF]

, 2004
The paper deals with the investigation of integration synergy of brake and suspension control for reduction of the stopping distance. The basic idea is to take a controllable suspension and to optimize it for decrease of road-tyre force fluctuation.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
