A Note on Roman Domination of Digraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2019
A vertex subset S of a digraph D is called a dominating set of D if every vertex not in S is adjacent from at least one vertex in S. The domination number of a digraph D, denoted by γ(D), is the minimum cardinality of a dominating set of D.

Corporate Dynamic Eco‐Innovation Capability and Carbon Emission Reduction: Evidence From African Listed Firms With the Role of Institutional Pressures

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite the global emphasis on simultaneous achievement of higher growth and lower pollution (green growth), the dynamic link between eco‐innovation and CO2 emissions remains inadequately understood globally and specifically in Africa, with a complex and diverse institutional and regulatory landscape.

Bounds on the global double Roman domination number in graphs [PDF]

open access: yes
Let $G$ be a simple graph of order $n$ and let $\gamma_{gdR}(G)$ be the global double Roman domination number of $G$. In this paper, we give some upper bounds on the global double Roman domination number of $G$.

How Transformational Supply Chain Leadership Affects Financial and Environmental Performance: The Mediating Role of Firm Resilience to Supply Disruption

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Existing literature indicates that transformational leadership in supply chains is critical to sustainability; however, little is known about how this leadership influences sustainability. The empirical literature has provided minimal focused analysis of transformational supply chain leadership and its effects on sustainability performance ...

Signed Total Roman Domination in Digraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
Let D be a finite and simple digraph with vertex set V (D). A signed total Roman dominating function (STRDF) on a digraph D is a function f : V (D) → {−1, 1, 2} satisfying the conditions that (i) ∑x∈N−(v)f(x) ≥ 1 for each v ∈ V (D), where N−(v) consists ...

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
