Occupancy fraction, fractional colouring, and triangle fraction [PDF]
Journal of Graph Theory, 2021 Given $\varepsilon>0$, there exists $f_0$ such that, if $f_0 \le f \le Δ^2+1$, then for any graph $G$ on $n$ vertices of maximum degree $Δ$ in which the neighbourhood of every vertex in $G$ spans at most $Δ^2/f$ edges, (i) an independent set of $G$ drawn uniformly at random has at least $(1/2-\varepsilon)(n/Δ)\log f$ vertices in expectation, and (ii)

The Last Fraction of a Fractional Conjecture [PDF]
SIAM Journal on Discrete Mathematics, 2010 Reed conjectured that for every $\varepsilon>0$ and every integer $Δ$, there exists $g$ such that the fractional total chromatic number of every graph with maximum degree $Δ$ and girth at least $g$ is at most $Δ+1+\varepsilon$. The conjecture was proven to be true when $Δ=3$ or $Δ$ is even.

Fractional permissions without the fractions [PDF]
Proceedings of the 13th Workshop on Formal Techniques for Java-Like Programs, 2011 Fractional permissions are a popular approach to reasoning about programs that use shared-memory concurrency. Abstractly, they provide a way of managing that either multiple readers or one writer thread can access a resource concurrently. Concretely, specification using fractional permissions typically requires the user to pick concrete mathematical ...

Optimizing soil washing remediation of mercury contaminated soil using various washing solutions and solid/liquid ratios [PDF]
E3S Web of Conferences, 2020 Most of the artisanal and small-scale gold miners in Indonesia as in the case of those who are in Banten Province, still use the amalgamation process in the gold extraction process. Therefore, mercury contamination could not be avoided.
