Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
InfoMat, EarlyView.A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Matching the Alcubierre and Minkowski spacetimes
European Physical Journal C: Particles and FieldsThis work analyzes the Darmois junction conditions matching an interior Alcubierre warp drive spacetime to an exterior Minkowski geometry. The joining hypersurface requires that the shift vector of the warp drive spacetime satisfy the solution of a ...

JCPP Advances, EarlyView.This study examined how emotional symptoms co‐develop from childhood to adolescence using longitudinal data from over 11,000 children and adolescents. Network analyses revealed reciprocal links between core symptoms of anxiety and depression, with no significant differences between males and females.

Symmetry, Integrability and Geometry: Methods and Applications, 2006 We construct new integrable coupled systems of N = 1 supersymmetric equations and present integrable fermionic extensions of the Burgers and Boussinesq equations. Existence of infinitely many higher symmetries is demonstrated by the presence of recursion

Halin's Grid Theorem for Digraphs
Journal of Graph Theory, EarlyView.ABSTRACT Halin showed that every thick end of every graph contains an infinite grid. We extend Halin's theorem to digraphs. More precisely, we show that for every infinite family ℛ ${\rm{ {\mathcal R} }}$ of disjoint equivalent out‐rays there is a grid whose vertical rays are contained in ℛ ${\rm{ {\mathcal R} }}$.

A New Efficient Hybrid Method Based on FEM and FDM for Solving Burgers’ Equation with Forcing Term
Journal of Applied MathematicsThis paper presents a study on the numerical solutions of the Burgers’ equation with forcing effects. The article proposes three hybrid methods that combine two-point, three-point, and four-point discretization in time with the Galerkin finite element ...

Strategic Change, EarlyView.ABSTRACT This study examines how CEO narcissism shapes corporate diversification strategies, addressing gaps in upper echelon and agency theories. Using a sample of 388 CEOs across 319 firms, we find that narcissistic CEOs drive higher levels of overall corporate diversification but exhibit a strategic trade‐off: they strongly favor unrelated ...

Quality‐driven reformulation of Plantago ovata enriched non‐fermented beef salami
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Plantago ovata (psyllium) is a hydrocolloid additive that is used widely in foods; however, meat applications of this bioactive ingredient are limited. This study evaluated the effects of 0% to 5% Plantago husk on non‐fermented beef salami during 60 days of storage. Proximate composition, physicochemical properties, texture profile,

Land Degradation &Development, EarlyView.ABSTRACT Ensuring the long‐term erosional stability of post‐mining landforms remains a major challenge in open‐pit mining. Reconstructed landscapes must support the agreed post‐mining land use, such as cattle grazing in the Hunter region of southeastern Australia, requiring stable pasture and minimal soil loss.
