Photo‐Switchable FRET‐Enabled Flexible Luminescent Films for Multilevel Optical Security

open access: yesCarbon Energy, EarlyView.
A light‐gated FRET composite integrates a Tb‐Phen donor and a spiropyran acceptor in a polyurethane matrix. Under 365 nm light, spiropyran is transformed into merocyanine, creating spectral overlap with Tb3+ emission and activating energy transfer. Visible light reverses the switch, restoring green emission and enabling reversible multilevel optical ...

Justification for the necessity of extraction and use of mine and quarry water during mining of ore deposits

open access: yesМінеральні ресурси України
The article deals with the issue of rational use of underground water, which enters mines (quarries) during mineral extraction and is discharged into the hydrographic network almost with no treatment, leading to its pollution.

Urban Mapping Accuracy Enhancement in High-Rise Built-Up Areas Deployed by 3D-Orthorectification Correction from WorldView-3 and LiDAR Imageries

open access: yesRemote Sensing, 2019
Orthorectification is an important step in generating accurate land use/land cover (LULC) from satellite imagery, particularly in urban areas with high-rise buildings.

Harnessing machine learning and optimization for informed chemical engineering decisions: A styrene reactor analysis

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This study shows that integrating multiple machine learning models with optimization and decision‐making improves chemical process design, and that a consensus‐based strategy across models provides more robust and reliable operating recommendations than any single model, especially under limited or noisy data conditions.

Planar Coulomb Gas on a Jordan Arc at Any Temperature

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study a planar Coulomb gas confined to a sufficiently smooth Jordan arc γ$\gamma$ in the complex plane, at inverse temperature β>0$\beta > 0$. Let Z¯nβ(γ)=Znβ(γ)((2cap(γ))βn2/2e(1−β/2)n(H(νe,γ)−H(νe,I)),$$\begin{equation*} \bar{Z}_{n}^\beta (\gamma)=\frac{Z_n^\beta (\gamma)}{((2\text{cap}(\gamma))^{\beta n^2/2}e^{(1-\beta /2)n(H(\nu _{e ...

Corporate Social Responsibility and Corporate Tax Avoidance in Europe: Evidence From the Anti‐Tax Avoidance Directives

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the relationship between corporate social responsibility (CSR) and corporate tax avoidance (CTA) in the European Union, exploiting institutional variation arising from CSR disclosure regimes and the introduction of the Anti‐Tax Avoidance Directives (ATAD).
