Regular factors of simple regular graphs and factor-spectra
TLDR
We determine all values of k for which every simple r -regular graph of order n and with edge-connectivity λ has a k -factor for which there exists a maximal set of m edge-disjoint k -factors. Expand

The round-up property of the fractional chromatic number for proper circular arc graphs
Let G = (V, E) be a graph and let k be a nonnegative integer. A vector c e ℤ V+ is called k-colorable iff there exists a coloring of G with k colors that assigns exactly c(v) colors to vertex v e V.Expand

Effects of aversive odour presentation on inhibitory control in the Stroop colour-word interference task
BackgroundDue to the unique neural projections of the olfactory system, odours have the ability to directly influence affective processes. Furthermore, it has been shown that emotional states canExpand

Service-based Resource Brokering for Grid-Based Data Mining
TLDR
The shift towards intrinsically distributed complex problem solving environments is prompting a need for new systems, which utilize the virtually unlimited data and computational resources of the Grid and at the same time hide all the related complexity from the user. Expand
