Rainbow Connection Number on Amalgamation of General Prism Graph

InPrime, 2019
Let  be a nontrivial connected graph, the rainbow-k-coloring of graph G is the mapping of c: E(G)-> {1,2,3,…,k} such that any two vertices from the graph can be connected by a rainbow path (the path with all edges of different colors).

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Graphs with 4-Rainbow Index 3 and n − 1

Discussiones Mathematicae Graph Theory, 2015
Let G be a nontrivial connected graph with an edge-coloring c : E(G) → {1, 2, . . . , q}, q ∈ ℕ, where adjacent edges may be colored the same. A tree T in G is called a rainbow tree if no two edges of T receive the same color. For a vertex set S ⊆ V (G),

Rainbow stackings of random edge‐colorings

Bulletin of the London Mathematical Society
AbstractA rainbow stacking of ‐edge‐colorings of the complete graph on vertices is a way of superimposing so that no edges of the same color are superimposed on each other. We determine a sharp threshold for (as a function of and ) governing the existence and nonexistence of rainbow stackings of random ‐edge‐colorings .

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

The 3-rainbow index of a graph [PDF]

, 2013
Let $G$ be a nontrivial connected graph with an edge-coloring $c: E(G)\rightarrow \{1,2,...,q\},$ $q \in \mathbb{N}$, where adjacent edges may be colored the same. A tree $T$ in $G$ is a $rainbow tree$ if no two edges of $T$ receive the same color. For a

Effect of Using Nisin and Ethylenediaminetetraacetic Acid on the Bacterial Load, Deterioration Criteria, and Sensory Attributes of Chilled Chicken Cuts

Food Safety and Health, EarlyView.
Evaluation of the efficacy of selected dipping solutions on fresh chicken meat shelf life. Samples treated with nisin and EDTA combinations, followed by chilled storage. The effectiveness of these interventions was assessed through bacteriological, sensory, and physicochemical (pH) deterioration criteria.

Toxic Metals in Dried Marine Fish and Implications for Human Health in Bangladesh and Exporting Countries

Food Safety and Health, EarlyView.
This study assessed toxic metals in five dried marine fish species from Bangladesh. Although most metals were within safe limits, chromium (Cr) consistently exceeded FAO/WHO standards, especially at Kuakata Beach. The findings highlight localized contamination hotspots and species‐specific bioaccumulation, while risk assessment supports the safety and ...
