Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

DIFFERENCE BETWEEN OF PWM STRATEGIES FOR INVERTER FED INDUCTION MOTOR
Journal of Engineering, 2009 Several sophisticated or "optimum" modulation strategies have been suggested for voltage source pulse with modulated (PWM) inverters for ac motor control. These modulation strategies may suppress specific low – order harmonics or minimize total harmonic.

MAFF Suppresses Necroptosis in Pancreatic Cancer via the GATA4‐MLKL Axis
Cancer Science, EarlyView.MAFF promotes pancreatic cancer progression by acting as a transcriptional repressor of the GATA4‐MLKL axis, thereby inhibiting necroptotic cell death. This study identifies the MAFF‐GATA4‐MLKL pathway as a novel therapeutic target and a significant prognostic biomarker for pancreatic adenocarcinoma.

Neural correlates of pure apathy in multiple sclerosis: An exploratory neuroimaging study
Journal of Neuropsychology, EarlyView.Abstract Pure apathy is relatively common in people with Multiple Sclerosis (PwMS), but its neural mechanisms remain unexplored. Therefore, we investigated the neural correlates of pure apathy in PwMS, differentiating it from depression. Sixty‐two PwMS underwent neuropsychological assessments and Magnetic Resonance Imaging scans.
