Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

An improved grid-forming control method with adaptive virtual impedance combining current limitation and transient stability improvement

International Journal of Electrical Power & Energy Systems
The virtual impedance (VI) control method is widely used to limit fault current for grid-forming converter (GFMC). However, in this article, it is found that the VI deteriorates the transient synchronization stability of the GFMC under grid faults.
