Bidirectional Tracking Robust Controls for a DC/DC Buck Converter-DC Motor System
Complexity, 2018 Two differential flatness-based bidirectional tracking robust controls for a DC/DC Buck converter-DC motor system are designed. To achieve such a bidirectional tracking, an inverter is used in the system.

Chaoization of DC Motors for Industrial Mixing
IEEE Transactions on Industrial Electronics, 2007 Conventional industrial mixing is ineffective, which consumes a lot of energy. In this paper, an effective mixing approach is proposed and implemented by using an electrical chaoization. Namely, a permanent-magnet DC motor, which acts as the agitator, is electrically chaoized by time-delay feedback control.

Comparison of Two DC Motor Speed Observers on Sensorless Speed Control Systems
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2022 In a sensorless motor speed control system, the motor speed is not directly measured using a speed sensor, but it is estimated using an observer. The sensorless speed control systems are mostly applied to AC motors, while they have not been widely ...

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 ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
