Edge cover and polymatroid flow problems

, 2010
In an $n$ by $n$ complete bipartite graph with independent exponentially distributed edge costs, we ask for the minimum total cost of a set of edges of which each vertex is incident to at least one.

Card games are effective tools to enhance foundation year health and safety inductions

FEBS Open Bio, EarlyView.
A series of three card games was developed to actively deliver health and safety education to foundation year students. Most students reported positive responses regarding their enjoyment (89.9 %) and learning (74.7 %) from all games evaluated. Data revealed significant improvements in health and safety knowledge (P < 0.0001).

Edge Clique Cover of Claw-free Graphs

, 2016
The smallest number of cliques, covering all edges of a graph $ G $, is called the (edge) clique cover number of $ G $ and is denoted by $ cc(G) $. It is an easy observation that for every line graph $ G $ with $ n $ vertices, $cc(G)\leq n $. G.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

FEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...
