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 ...

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 ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Current-Mode Controlled Battery Emulator
ProcessesThis paper proposes a battery emulator based on a bidirectional non-inverting buck-boost power electronics converter. With the capability of bidirectional operation, it can emulate both charging and discharging processes. The proposed emulator is controlled with the advanced I2 dual current-mode control (I2DCMC) algorithm, combined with a feedforward ...

Current Inverter in the Sliding Mode for Induction Motor Control
IFAC Proceedings Volumes, 1983 Abstract This paper presents a method for realizing motor set currents using voltage inverter with fixed DC link voltage. Certain algorithms for AC motor speed control are based on use of stator currents as control actions to the motor. Realization of such currents presents a difficult problem since classical current inverters cannot meet high ...
