How Political Connections Shape Corporate Sustainability: A Systematic Review and Integrative Framework for Future Research Directions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The intersection between corporate entities and political institutions—commonly referred to as corporate political connections (CPCs)—significantly influences firms' strategic conduct and their environmental obligations. Although academic interest in this area has grown, the ethical dimensions of CPCs in relation to environmental ...

Roman domination on graphs [PDF]

open access: yes, 2010
A Roman dominating function of a graph G is a function f : V (G) → {0, 1, 2} such that whenever f(v) = 0 there xists a vertex u adjacent to v such that f(u) = 2. The weight of f is w(f) = Pv∈V (G) f(v).

New Sharp Extremal Bounds for the Randić Index of Trees With Prescribed Roman Domination Number

open access: yesDiscrete Dynamics in Nature and Society
The Randić index is a classical degree-based topological index that captures branching features of a graph and has broad applications in chemical graph theory and related network models.

A Novel Anatomical Description of the Normal Terminal Fibular Artery and the Terminal Fibular Window: Radiological Findings and Surgical Implications

open access: yesClinical Anatomy, EarlyView.
ABSTRACT A novel anatomical description and radiological finding, related to the anatomical course of the terminal fibular artery (FibA) was recently reported. In the article, the authors found the terminal FibA to change its course, from being posterior and medial to the fibula to surface anteriorly and laterally before residing below the tibiofibular

Quasi total double Roman domination stability in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
A quasi total double Roman dominating function (QTDRD-function) on a graph [Formula: see text] is a function [Formula: see text] having the property that [Formula: see text] if [Formula: see text], then the vertex v must have at least two neighbors ...

Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

open access: yesChemistry – A European Journal, EarlyView.
Syntheses of pentafluoroethyl substituted plumbanes in the formal oxidation states +II, +III, and +IV are reported. The compounds were characterized by multinuclear NMR spectroscopy, including 207Pb NMR spectroscopy, mass spectrometry and single‐crystal x‐ray diffraction experiments. ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type

On $f$-domination number of a graph [PDF]

open access: yes, 1990
summary:Let $G=(V, E)$ be a simple graph. A subset $S\subseteq V$ is a dominating set of $G$, if for any vertex $u\in V-S$, there exists a vertex $v\in S$ such that $uv\in E$.

Photoinduced ROS Production by Poly(3‐hexylthiophene) (P3HT) is due to Autoxidation Rather Than Catalysis

open access: yesChemistry – A European Journal, EarlyView.
P3HT is widely treated as a photocatalyst that generates ROS under light. We show otherwise: ROS production comes at the expense of the polymer itself. Photoexcited P3HT acts as a self‐sacrificial photosubstrate, undergoing irreversible autoxidation during light‐driven oxygen reduction—a distinction critical for interpreting its behavior in emerging ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.
