An adaptive fuzzy controller using an interval type‐3 fuzzy logic system replaces the SMC switching term to mitigate chattering while preserving global stability for islanded inverters. Simulations show lower THD, greater robustness to disturbances and parameter variations, and improved voltage‐tracking accuracy, with applicability to other uncertain ...

The CNS Meninges and the Synovial Joint: Parallel Immunological Structures in Autoimmune Disease
The meninges and synovium share multiple functional and structural characteristics and act as specialized immunological barriers. In MS and RA, both can host tertiary lymphoid organs (TLOs) and CD4+ Tph cells. We highlight how these features sustain compartmentalized inflammation and explore a possible role for EBV in their formation and persistence ...
