Discrete Implementations Modify the Intuition of Final Set Adjustment in Barrier Function Based Control

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper establishes an implementation‐aware framework for Barrier Function Adaptation (BFA) and shows that discrete‐time realizations fundamentally alter the logic of final‐set adjustment. In particular, sufficient conditions are derived to preserve the key benefits of BFA (predefined performance, gain adaptation with uncertain perturbation

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This
