Self‐compensation of DC–DC converters under peak current mode control

Electronics Letters, 2017
A new self‐compensation technique is proposed for eliminating subharmonic oscillation and chaotic regimes in dc–dc switching converters under peak current mode control.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Virtual Impedance Sliding Mode Control-Based MMC Circulating Current Suppressing Strategy

IEEE Access, 2019
The device rated capacity, system loss, and cost of a modular multilevel converter are proportional to the circulating current value. In order to enhance suppressing the second order harmonic component of circulating current and improve the dynamic ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Hybrid-mode control for grid-connected inverters and characteristics comparison with current-source mode and voltage-source mode

International Journal of Electrical Power & Energy Systems
The grid-connected inverters (GCIs) controlled by traditional Current-Source Mode (CSM) and Voltage-Source Mode (VSM) face challenges in simultaneously meeting the requirements for small-signal stability, power-response, and grid-support.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A Multi-Mode Hybrid Control Strategy With Seamless Transition for Constant-Current Charging in LCC Resonant Capacitor Charging Power Supply

IEEE Open Journal of Power Electronics
A multi-mode hybrid control strategy with seamless switching capability is proposed to address the issues of excessively wide operating frequency range and low light-load efficiency in traditional LCC resonant capacitor charging power supplies(CCPS ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Robust digital voltage mode control of buck converter with enhanced tracking performance [PDF]

Al-Qadisiyah Journal for Engineering Science
The digital voltage controller of power converters is used because it has many advantages over its analog counterparts. Thus, in this paper, a controller of digital voltage mode is designed and analyzed for a non-isolated DC-DC buck converter in ...
