AC-Side Impedance-Based Stability Assessment in Grid-Forming Modular Multilevel Converters

IEEE Access
Grid-forming converters can emulate the behavior of a synchronous generator through frequency droop control. The stability of grid-forming modular multilevel converters can be studied via the impedance-based stability criterion. This paper presents an ac-

Interaction energy-based power coupling oscillation analysis and suppression of grid-forming converter connected system

International Journal of Electrical Power & Energy Systems
The power coupling effect of the grid-forming converter will cause instability oscillation when it connects to low-voltage short-distance transmission lines. To solve this problem, this paper presents an energy interaction analysis method for oscillation

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
