Quantifying permeability of linear barriers to animal movement: The permeability R package

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2039-2051, July 2026.
Abstract Animals have always navigated environments characterized by linear features that influence movement, whether rivers, ridges or ravines. Large‐scale changes in land use have led to increasing interactions with anthropogenic features, especially roads and fences.

Oxoaporphine‐Metformin Rhodium(III) Hybrid Ionic Complex With Antidiabetes and Anticancer Effects: New Insights From DFT Computations

International Journal of Quantum Chemistry, Volume 126, Issue 12, June 15, 2026.
DFT (GGA) analysis reveals that the Rh‐Met metallodrug forms a stable ionic pair driven by a network of supramolecular interactions. QTAIM and IGMH insights elucidate the quantum‐mechanical nature of intra‐ and intermolecular contacts governing its self‐assembly and structural organization in the crystal. ABSTRACT A recently proposed (J. Am. Chem. Soc.

Sodium Tetraazidoaurate(III)—From Na[AuCl4]·2H2O to Na[Au(N3)4] and Beyond One Step at a Time

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Novel sodium chlorido‐/azidoaurate(III) dihydrates Na[AuCl4–x(N3)x]·2H2O (x = 0, 1, 2, 3, 4) provide the first example of a complete series of gradual substitution on tetramer complex anions to be described. Controlled dehydration of Na[Au(N3)4]·2H2O leads to Na[Au(N3)4]·H2O and Na[Au(N3)4], the latter being a highly explosive material.

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

Kunneth formula for Hessian manifolds

We study Dolbeault--Koszul cohomology $H^{p,q}(M)$ of flat affine manifolds. We proove a Künneth formula \[ H^{p,q}(M\times N) \cong \bigoplus_{i,j} H^{i,j}(M)\otimes H^{p-i,q-j}(N) \] for flat affine manifolds $M,N$ with at least one compact. For compact manifolds we also give a proof via Hodge theory on flat affine manifolds, analogous to the ...

Curvature of Hessian manifolds

Curvature of Hessian manifolds
We prove that, in dimensions greater than 2, the generic metric is not a Hessian metric and find a curvature condition on Hessian metrics in dimensions greater than 3. In particular we prove that the forms used to define the Pontryagin classes in terms of the curvature vanish on a Hessian manifold.
