Minimal hypersurfaces in $\mathbb{S}^5$ with constant scalar curvature and zero Gauss curvature are totally geodesic

We show that a closed minimal hypersurface in $\mathbb{S}^5$ with constant scalar curvature and zero Gauss curvature is totally geodesic.11 pages, no ...

Free Vibration of Hemp Fiber‐Reinforced Laminated Composite Curved Beams Using Generalized Differential Quadrature Method

Polymer Composites, Volume 47, Issue 12, Page 11300-11318, 20 June 2026.
Schematic representation of hemp‐, glass‐, and carbon‐based laminated composite curved beams, including different stacking sequences and their vibration response. ABSTRACT In recent years, increasing environmental awareness has stimulated growing interest in natural fiber‐reinforced composites (NFRCs) due to their eco‐friendly composition ...

Volume preserving nonhomogeneous Gauss curvature flow in hyperbolic space

We consider the volume preserving flow of smooth, closed and convex hypersurfaces in the hyperbolic space $\mathbb{H}^{n+1}$ with speed given by a general nonhomogeneous function of the Gauss curvature. For a large class of speed functions, we prove that

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.

Analysis of Branching Mechanisms for Post‐Transition State Bifurcation Reactions Using Molecular Dynamics Simulations

International Journal of Quantum Chemistry, Volume 126, Issue 11, June 5, 2026.
Systematic molecular dynamics simulations on 18 intramolecular cycloadditions reveal two distinct post‐transition‐state bifurcation regimes—distinguished by the position of the valley–ridge transition (VRT) point along the reaction path—whose branching fractions are quantitatively predicted by a two‐parameter descriptor combining the VRT lateral offset
