A Coarse Geometric Approach to Graph Layout Problems

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

The impact of person-group fit on knowledge hiding: Mediating role of work-group identification

open access: yesSouth African Journal of Economic and Management Sciences
Background: Knowledge hiding behaviour (KHB) is a pervasive problem, and many organisations are vigorously pursuing avenues to alleviate this harmful behaviour. In the academic literature, studies investigating the predictors of KHB have been restricted,

Zukunftstechnologien bei der Stromerzeugung: Elektrizität im internationalen Vergleich

open access: yesPhysik in unserer Zeit, EarlyView.
Welche Technologien setzen sich bei der Stromerzeugung gerade durch? Die Antwort sieht man eindeutig in den Trends von weltweiten Stromerzeugungsdaten. Analysiert man diese Daten mithilfe der Theorie der Diffusion von Innovationen, dann zeigt sich, wie Photovoltaik und Wind sich weltweit durchsetzen.

Process mapping improvement: Extending value stream maps with waste identification diagrams [PDF]

open access: yesFME Transactions, 2015
Value Stream Mapping (VSM) is likely the most common tool to represent and analyse the value stream of product families. However, it has several limitations, recognized by professionals and academics, namely in terms of identification of certain types of

Evolution of regulatory networks associated with traits under selection in cichlids

open access: yesGenome Biology, 2021
Background Seminal studies of vertebrate protein evolution speculated that gene regulatory changes can drive anatomical innovations. However, very little is known about gene regulatory network (GRN) evolution associated with phenotypic effect across ...

High-Dimensional Expanders from Expanders [PDF]

open access: yes, 2019
We present an elementary way to transform an expander graph into a simplicial complex where all high order random walks have a constant spectral gap, i.e., they converge rapidly to the stationary distribution.

C. A. Sandstén – ”wisförfattare och sångare wid positiv”

open access: yesSvensk tidskrift för musikforskning / Swedish Journal of Music Research, 2022
Carl August Sandstén, som var verksam kring mitten av 1870-talet, kombinerade visförfattande och visförsäljning med sång och positivspel. Mekaniska musikinstrument har en lång historia, men kring 1830/40-talen var de bärbara vevpositiven en nyhet för allmänheten.

Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen

open access: yesPhysik in unserer Zeit, EarlyView.
Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.
