Ecology and Evolution, Volume 16, Issue 9, September 2026.Lepidopteran stemborer populations in wild habitats are increasingly influenced by anthropogenic disturbances, including urbanization and agricultural intensification in addition to climate change, which alter community composition and diversity within fragmented native ecosystems.

The companion equations and the moyal-nahm equations [PDF]
, 2000 The first part of this thesis is concerned with the companion equations. These are equations of motion for the companion Lagrangian which is proposed to be the Lagrangian for a field theory associated with strings and branes, similar to the Klein-Gordon ...

Stress and Health, Volume 42, Issue 4, August 2026.ABSTRACT Exercise is suggested to help regulate emotions; however, its role in the underlying cognitive emotion regulation process—starting with a cue, cognitive actions to modify emotions, and desirable emotional changes—has not yet been demonstrated.

Theoria, Volume 92, Issue 4, August 2026.ABSTRACT Some commentators argue that the notes collected as Wittgenstein's On Certainty provide the basis for a groundbreaking epistemological theory and response to scepticism. This theory pertains to the role of what some have called the hinge propositions of our inquiry, following Wittgenstein's metaphor of hinges of a door. This paper examines one

Mizohata–Takeuchi inequalities for orthonormal systems
Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.Abstract We establish some weighted L2$L^2$ inequalities for Fourier extension operators in the setting of orthonormal systems. In the process, we develop a direct approach to such inequalities based on generalized Wigner distributions, complementing the Schatten space approach that is prevalent in the wider context of estimates for such orthonormal ...

Fourier Expansion‐Based Approach to the Parameter Space of Classical Systems
Annalen der Physik, Volume 538, Issue 7, July 2026.ABSTRACT We propose a new approach to compute the classical metric tensor (CMT) and the Hannay curvature using Fourier series expansions in action‐angle variables. This approach circumvents the need for complex time‐domain integrals or the construction of generating functions, replacing them with algebraic combinations of Fourier coefficients. We prove

A unifying perspective on the Moyal and Voros products and their physical meanings [PDF]
Journal of Physics A: Mathematical and Theoretical, 2011 The Moyal and Voros formulations of non-commutative quantum field theory has been a point of controversy in the recent past. Here we address this issue in the context of non-commutative non-relativistic quantum mechanics. In particular we show that the two formulations simply correspond to two different representations associated with two different ...

Quantum Fields on Noncommutative Spacetimes: Theory and Phenomenology
Symmetry, Integrability and Geometry: Methods and Applications, 2010 In the present work we review the twisted field construction of quantum field theory on noncommutative spacetimes based on twisted Poincaré invariance.
