Dietary lipids provide energy for growth and development fatty acids necessary normal structure biological function. However, oxidized cause oxidative stress intestinal damage. An 8-week feeding trial with fresh fish oil (FFO, control group), (OFO), taurine-supplemented diets (OFOT, OFO + 0.2% of taurine) was conducted to evaluate the protective effect taurine on fish-oil-induced liver intestine impairment in juvenile Ictaluruspunctatus. The results showed that (1) Growth performance...

Due to the numerical subsystems and functionalities among platoon, failures easily occur lead vehicle safety stability deteriorate. With surge of platoon connectivity, abnormal states arising in faulty vehicles will have an impact on adjacent healthy vehicles, potentially resulting severe traffic accidents. To address aforementioned problems improve functional platoons, a systemic anti-fault consensus strategy is proposed this article deal with sensor faults, LOE actuator bias faults...

Regenerative braking provided by an electric powertrain is very different from conventional friction with respect to the system dynamics.
