Nine‐level voltage‐doubler bi‐polar module for multilevel DC to AC power conversion
IET Power Electronics, 2019 A major disadvantage of two-stage topologies of switched capacitors based multilevel inverters is the use of H-bridge switches which endure high peak-inverse-voltage (PIV).

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer
FEBS Letters, EarlyView.Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Characteristics of Single-Phase Voltage-Doubler Rectifier with Balanced Capacitor Voltages
IEEJ Transactions on Industry Applications, 2001 A single-phase voltage-doubler rectifier, which has two auxiliary bidirectional switches, is studied. The proposed rectifier has the advantages that the imbalance of the voltages across the capacitors, connected in series, is minimized independent of the working conditions and the discharge of capacitors is adjusted by arranging two auxiliary ...

A comparison of AC/DC piezoelectric transformer converters with current doubler and voltage doubler rectifiers [PDF]
IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2004 The objective of this study was to develop recommendations for an optimal design of PT AC/DC converters. The paper presents a comprehensive comparison of the two commonly used rectifier topologies in a piezoelectric transformer (PT) based power converters: current doubler and voltage doubler rectifiers.

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
