Edge Odd Graceful Labeling in Some Wheel-Related Graphs

open access: yesMathematics
A graph’s edge labeling involves the allocation of symbols (colors or numbers) to the edges of a graph governed by specific criteria. Such labeling of a graph G with order n and size m is named edge odd graceful if there is a bijective map φ from the set

WHEEL AS AN EDGE-MAGIC GRAPH [PDF]

open access: yesInternational Journal of Pure and Apllied Mathematics, 2013
An image of a plane graph, G = (V,E) of order n and size m, is said to be an edge-magic plane graph if there is a bijection f : E → {1,2,..,m} such that for all s−side faces of G, except the infinite face, the sum of the labels of its edges is a constant k(s). Such a bijection will be called an edge-magic plane labeling of G.

Tree Independence Number III. Thetas, Prisms and Stars

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We prove that for every t ∈ N $t\in {\mathbb{N}}$ there exists τ = τ ( t ) ∈ N $\tau =\tau (t)\in {\mathbb{N}}$ such that every (theta, prism, K 1 , t ${K}_{1,t}$)‐free graph has tree independence number at most τ $\tau $ (where we allow “prisms” to have one path of length zero).

SIS Process with Heterogeneous Infection Rates in Wheel Graphs

open access: yesMathematics
The studies in epidemic-like processes have drawn much attention for the last decades. Structural or dynamical heterogeneity has been reported to have great impact on the statistical properties of the epidemic dynamics.

Saturated Partial Embeddings of Planar Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT In this work, we study how far one can deviate from optimal behavior when embedding a planar graph. For a planar graph G $G$, we say that a plane subgraph H ⊆ G $H\subseteq G$ is a plane‐saturated subgraph if adding any edge (possibly with new vertices) to H $H$ would either violate planarity or make the resulting graph no longer a subgraph of

High‐Throughput Quantitative Chemical Shift‐Encoded MRI of the Liver

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Access to MRI is limited by lengthy exam times and inefficient utilization. Focused protocols can reduce exam times, but workflow variability and inefficient room turnaround contribute to conservative scheduling with long exam slots.

Quadratic Embedding Constants of Wheel Graphs

open access: yesInterdisciplinary Information Sciences, 2017
Summary: A connected graph is said to be of QE class if it admits a quadratic embedding in a Hilbert space, or equivalently if the distance matrix is conditionally negative definite, or equivalently if the quadratic embedding constant (QEC) of a graph is non-positive. The QEC of wheel graphs are calculated explicitly.

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Consumers' sensory assessments of bigleaf maple (Acer macrophyllum) syrup give way to a promising artisan industry

open access: yesJSFA reports, Volume 5, Issue 3, Page 113-124, March 2025.
Abstract Background Most pure maple syrup produced in North America is produced from the sap of sugar maple trees (Acer saccharum). Interest is growing to utilize other maple species in different regions of North America outside the native range of sugar maple.
