Anti-Ramsey theory on complete bipartite graphs
AKCE International Journal of Graphs and Combinatorics, 2020 We consider quadruples of positive integers with and such that every proper edge-coloring of the complete bipartite graph contains a rainbow subgraph. We show that every such quadruple with and satisfies this property and find an infinite sequence where ...

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio)
Environmental Toxicology, EarlyView.ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...

Environmental Toxicology, EarlyView.ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Environmental Toxicology, EarlyView.ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Chromatic Spectrum of $K_s$-WORM Colorings of $K_n$ [PDF]
Computer Science Journal of Moldova, 2020 An {\it $H$-WORM} coloring of a simple graph $G$ is the coloring of the vertices of $G$ such that no copy of $H\subseteq G$ is monochrome or rainbow. In a recently published article by one of the authors \cite{All1}, it was claimed that the number of $r$

Rainbow and strong rainbow connection number for some families of graphs
, 2020 Let G be a nontrivial connected graph. Then G is called a rainbow connected graph if there exists a coloring c : E(G) → {1, 2, ..., k}, k ∈ N, of the edges of G, such that there is a u − v rainbow path between every two vertices of G, where a path P in G
