    • This paper summarizes the submissions to a recently announced contact-mechanics modeling challenge. The task was to solve a typical, albeit mathematically fully defined problem on the adhesion between nominally flat surfaces. The surface topography of the rough, rigid substrate, the elastic properties of the indenter, as well as the short-range adhesion between indenter and substrate, were specified so that diverse quantities of interest, e.g., the distribution of interfacial stresses at a given load or the mean gap as a function of load, could be computed and compared to a reference solution. Many different solution strategies were pursued, ranging from traditional asperity-based models via Persson theory and brute-force computational approaches, to real-laboratory experiments and all-atom molecular dynamics simulations of a model, in which the original assignment was scaled down to the atomistic scale. While each submission contained satisfying answers for at least a subset of the posed questions, efficiency, versatility, and accuracy differed between methods, the more precise methods being, in general, computationally more complex. The aim of this paper is to provide both theorists and experimentalists with benchmarks to decide which method is the most appropriate for a particular application and to gauge the errors associated with each one..

  • Novel Er:Yb phosphate glass fiber laser pumped by a 946 nm Nd:YAG laser
  • 2001

    • Summary form only given. Recently, Kigre introduced a new family of rare-earth doped fibers (Wu et al, 2000), based on phosphate laser glass. Due to their phonon energy, erbium-doped phosphate glasses exhibit lower up-conversion losses than silica glass. This, and the high solubility for rare-earth ions, makes phosphate glasses promising candidates for high-gain erbium devices. High doping concentrations enable short devices, and fiber lasers or amplifiers with only a few centimeters of active fiber can be realized. This is to be compared to standard EDFAs that normally contain tens of meters of erbium-doped silica fibers. We have demonstrated a short fiber-laser based on a single-mode Er:Yb codoped phosphate fiber, pumped by a 946 nm Nd:YAG laser.

  • Genome-Wide Association Study (GWAS) identified novel candidate loci affecting wood formation in Norway spruce
  • 2019
  • Ingår i: The Plant Journal. - : Wiley. - 0960-7412 .- 1365-313X. ; 100:1, s. 83-100

    • Norway spruce is a boreal forest tree species of significant ecological and economic importance. Hence there is a strong imperative to dissect the genetics underlying important wood quality traits in the species. We performed a functional Genome-Wide Association Study (GWAS) of 17 wood traits in Norway spruce using 178101 single-nucleotide polymorphisms (SNPs) generated from exome genotyping of 517 mother trees. The wood traits were defined using functional modelling of wood properties across annual growth rings.We applied a LASSO based association mapping method using a functional multi-locus mapping approach that utilizes latent traits, with a stability selection probability method as the hypothesis testing approach to determine significant Quantitative Trait Loci (QTLs). The analysis provided 52 significant SNPs from 39 candidate genes, including genes previously implicated in wood formation and tree growth in spruce and other species. Our study represents a multi-locus GWAS for complex wood traits in Norway spruce. The results advance our understanding of the genetics influencing wood traits and identifies candidate genes for future functional studies.
