Advanced Materials Technologies, EarlyView.This review summarizes moisture‐adaptive strategies that enable triboelectric nanogenerators (TENGs) to operate across diverse moisture conditions. It examines moisture‐management methods, including exclusion, directional transport, removal, and utilization, with charge‐regulation approaches based on interfacial, dielectric, and structural engineering.

New Special Conformal Killing vector fields for Abelian and Yang-Mills theories
We will introduce new Special Conformal Killing vector fields for geometrodynamics. For Abelian and Yang-Mills theories. We will take advantage of the remarkable properties of the new tetrads introduced previously in order to construct these new Killing ...

On The Triviality Of $m$-Modified Conformal Vector Fields [PDF]
We prove that a compact Riemannian manifold $M$ does not admit any non-trivial $m$-modified homothetic vector fields. In the corresponding case of an $m$-modified conformal vector field $V$, we establish an inequality that implies the triviality of $V ...

Projective Vector Fields on Semi-Riemannian Manifolds
MathematicsThis paper explores the properties of projective vector fields on semi-Riemannian manifolds. The main result establishes that if a projective vector field P on such a manifold is also a conformal vector field with potential function ψ and the vector ...

Even spin N = 4 $$ \mathcal{N}=4 $$ holography
Journal of High Energy Physics, 2017 A two-dimensional Sp(2N ) vector model with small N = 4 $$ \mathcal{N}=4 $$ superconformal symmetry is formulated, and its chiral algebra is shown to be freely generated by super-primary fields of even conformal weight.

Semi-universality of conformal higher-derivative and conformal higher-spin fields
Journal of High Energy PhysicsIn this paper, we study thermal partition functions of free exotic conformal field theories, focusing on conformal higher-derivative and conformal higher-spin fields, in the semi-universal limit |ω i | → 1.
