A Shaft Generator System without Output Voltage Distortion
IEEJ Transactions on Industry Applications, 1999 A shaft generator system, which consists of a shaft generator, a rectifier, an externally commutated thyristor inverter, an ac reactor, and a synchronous condenser, is being increasingly used mainly in large ships. Conventional type of the shaft generator system has a fundamental drawback of involving a large amount of harmonics in the output voltage ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells
Molecular Oncology, EarlyView.We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox
