An eight‐switch five‐level inverter with zero leakage current
IET Power Electronics, 2021 This paper examines a multilevel transformer‐less grid‐tied inverter topology is proposed for PV applications. Nowadays, transformer‐less inverters are more desirous due to their small filter size, cheaper and higher efficiency.

Modified capacitor voltage balancing sorting algorithm for modular multilevel converter
The Journal of Engineering, 2019 The modular multilevel converter (MMC) with large-scale sub-modules has the advantage of simpler modulation, lower switching frequency, and lower harmonic component, thus would be very promising in voltage source converter (VSC)–high voltage direct ...

Hierarchical voltage balancing method for MMC based on DCSM
IET Power Electronics, 2022 This paper presents a hierarchical voltage balance control method for a hybrid modular multi‐level converter based on half‐bridge submodule and dual‐capacitor submodule. This voltage balancing method reduces the control complexity of the existing voltage

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
