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 ...

Governing Marginality Through Crime: The Cameron Government's ‘Thug State’ Responses to the August 2011 English Riots

International Social Science Journal, EarlyView.
ABSTRACT This article examines the British government's response to the August 2011 English riots through the lens of state crime, drawing on Richards and Avery's ‘Thug State’ concept. It addresses the relative neglect of the state's response itself as a potential form of criminality and social harm.

A Call to Action: Challenges and Future Directions for Sleep Health in Europe

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep is fundamental to physical, cognitive, and emotional health and wellbeing. However, it is increasingly threatened by environmental, social, technological, and cultural pressures. To identify key priorities for improving sleep health across Europe, the European Sleep Research Society (ESRS)'s Equality, Diversity and Inclusion Committee ...

Entanglement, Space–Time Coordinates, and Bell's Inequalities in Photon–Polarization Experiments

Annalen der Physik, Volume 538, Issue 9, September 2026.
This work presents a revised analysis of Bell‐type inequalities. It is argued that standard derivations of Bell‐type inequalities implicitly rely on additional assumptions beyond those originally stated, specifically concerning the cardinalities of the sets of measurements and photon‐pair properties.

Learning Vertical Coordinates via Automatic Differentiation of a Dynamical Core

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Terrain‐following coordinates in atmospheric models often imprint their grid structure onto the solution, particularly over steep topography, where distorted coordinate layers can generate spurious horizontal and vertical motion. Standard formulations, such as hybrid or SLEVE coordinates, mitigate these errors by using analytic decay functions

Generalization of the Fuzzy Fejér–Hadamard Inequalities for Non-Convex Functions over a Rectangle Plane

Axioms
Integral inequalities with generalized convexity play a vital role in both theoretical and applied mathematics. The theory of integral inequalities is one of the branches of mathematics that is now developing at the quickest rate due to its wide range of

Learning 2D Shallow Water Equations With Physics‐Informed Neural Operator Networks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract This study investigates the application of Physics‐Informed Neural Operators (PINOs) for solving the two‐dimensional shallow water equations (2D SWE) in the context of flood modeling. Unlike Physics‐Informed Neural Networks (PINNs), which require retraining for each new initial or boundary condition (BC), PINOs learn the solution operator ...
