A new soft‐switching high step‐down DC‐DC converter for voltage regular module application
IET Circuits, Devices and Systems, 2022 This study proposes a high step‐down DC‐DC converter with minimum elements. In the proposed converter, soft switching condition is provided with only one auxiliary switch, which simplifies the structure of the converter.

Zero Voltage Switching Converters
, 2014 Contact is the principal method of applying loads between deformable solids,and therefore is present in a wide variety of mechanical components. In addition,contacts usually act as stress concentrations,and are thus probable locations for mechanical failure.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
