Impact of Digital Control Delay on Stability of Grid-Following Converters

2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022
In a digital controlled system, the delay is inevitable. It will change the phase-frequency characteristics of the system, which will affect the stability. This paper analyzes the configuration of the grid-following converter and builds its small-signal model in detail.

Power-Synchronized Grid-Following Inverter Without a Phase-Locked Loop

IEEE Access, 2021
This paper proposes a power-synchronized control strategy for grid-following inverters (GFLIs) to regulate their power exchange with the grid without any need for sensing/regulating the point of connection voltage.

Modeling and Control of Grid Forming Converters: A Systematic Review

IEEE Access
In electrical power systems where the proportion of synchronous generators (SG) is gradually decreasing, grid-forming (GFM) converters need to be installed and controlled to meet all the system requirements that SGs have provided to date.

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

Molecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.

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
