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 ...

Fractional Coins and Fractional Derivatives [PDF]
Abstract and Applied Analysis, 2013 This paper discusses the fundamentals of negative probabilities and fractional calculus. The historical evolution and the main mathematical concepts are discussed, and several analogies between the two apparently unrelated topics are established. Based on the new conceptual perspective, some experiments are performed shading new light into possible ...

On the Relations Between Excess Fraction, Attributable Fraction, and Etiologic Fraction [PDF]
American Journal of Epidemiology, 2012 It has been noted that there is ambiguity in the expression "attributable fraction," and epidemiologic literature has drawn a distinction between "excess fraction" and "etiologic fraction." These quantities do not necessarily approximate one another, and the etiologic fraction is not generally estimable without strong biologic assumptions.

Characterization and degradation of pectin derived from Budimka apple [PDF]
Journal of the Serbian Chemical Society, 2008 The characterization of apple pectin and its oligogalacturonic fractions derived from the autochthones apple variety Budimka, characteristic for central Serbia, is described in this paper.

Self-aggregation of soil humic acids with respect to their structural characteristics [PDF]
Journal of the Serbian Chemical Society, 2022 The main goal of this work was to estimate the influence of carboxyl and phenolic groups, as well as aromatic, aliphatic and polysaccharide components, on the soil humic acids (HA) self-aggregation process.

Fractional free space, fractional lenses, and fractional imaging systems [PDF]
Journal of the Optical Society of America A, 2003 Continuum extensions of common dual pairs of operators are presented and consolidated, based on the fractional Fourier transform. In particular, the fractional chirp multiplication, fractional chirp convolution, and fractional scaling operators are defined and expressed in terms of their common nonfractional special cases, revealing precisely how they ...
