Planarized and Twisted Intramolecular Charge Transfer: Small Geometric, Huge Photophysical Changes
European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.Molecular motion governs excited state relaxation in aminobenzonitrile donor–acceptor systems. Small structural modifications control single and dual rotations and enable distinct relaxation pathways. Fluorescence spectroscopy, Lippert–Mataga analysis, and theoretical calculations identify multiple excited states, including a dual‐emitting planarized ...

Energy and Planarity in Boron‐Nitrogen Fulvene Isomers: A Quantum‐Chemical and QSPR Study
International Journal of Quantum Chemistry, Volume 126, Issue 15, August 5, 2026.Electronic structure quantum‐chemical computations and Quantitative Structure–Property Relationships (QSPR) regression and classification models are used as complementary tools for classifying unknown boron‐nitrogen fulvene isomers with respect to energy order and planarity.

Fortschritte der Physik, Volume 74, Issue 8, August 2026.ABSTRACT We analytically construct initial data for binary black hole systems by solving the Einstein constraint equations within the Bowen–York framework. Allowing for arbitrarily oriented linear momenta and spins, we obtain a perturbative solution of the vacuum Hamiltonian constraint up to third order in the source parameters. Our solution explicitly

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.ABSTRACT Conformity of observed data with a postulated probability distribution is a fundamental problem of statistical modeling. Current tools for checking distributional conformity are often limited to univariate settings, with extensions to multivariate distributions facing challenges in interpretability and power.

Centro-affine hypersurface immersions with parallel cubic form
, 2014 International audienceWe consider non-degenerate centro-affine hypersurface immersions in R^n whose cubic form is parallel with respect to the Levi-Civita connection of the affine metric.

Polar Varieties and Efficient Real Equation Solving: The Hypersurface Case
, 1996 The objective of this paper is to show how the recently proposed method by Giusti, Heintz, Morais, Morgenstern, Pardo [10] can be applied to a case of real polynomial equation solving.

Two theorems on (ϵ)-Sasakian manifolds
International Journal of Mathematics and Mathematical Sciences, 1998 In this paper, We prove that every (ϵ)-sasakian manifold is a hypersurface of an indefinite kaehlerian manifold, and give a necessary and sufficient condition for a Riemannian manifold to be an (ϵ)-sasakian manifold.

On the positivity and integrality of coefficients of mirror maps
Bulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.Abstract We present natural conjectural generalisations of the ‘positivity and integrality of mirror maps’ phenomenon, encompassing the mirror maps appearing in the Batyrev–Borisov construction of mirror Calabi–Yau complete intersections in Fano toric varieties as a special case.
