Coherent multidimensional spectroscopy in the gas phase
Recent work applying multidimentional coherent electronic spectroscopy at dilute samples in the gas phase is reviewed. The development of refined phase cycling approaches with improved sensitivity has opened up new opportunities to probe even dilute gas-phase samples. In this context, first results of two-dimensional spectroscopy performed at doped helium droplets reveal the femtosecond dynamics u
New molecular methods to assess biodiversity. Potentials and pitfalls of DNA metabarcoding: a workshop report
This report presents the outcome of the joint work of PhD students and senior researchers working with DNA-based biodiversity assessment approaches with the goal to facilitate others the access to definitions and explanations about novel DNA-based methods. The work was performed during a PhD course (SLU PNS0169) at the Swedish University of Agricultural Sciences (SLU) in Uppsala, Sweden. The cours
Open Data Collaborations - A snapshot of an emerging practice
Data defined software is becoming more and more prevalent, especially with the advent of machine learning and artificial intelligence. With data defined systems come both challenges - to continue to collect and maintain quality data - and opportunities - open innovation by sharing with others. We propose Open Data Collaboration (ODC) to describe pecuniary and non-pecuniary sharing of open data, si

A socio-technical perspective to counter cyber-enabled industrial espionage
The ubiquitous digitization of information and the pervasive connectivity of work systems have inevitably facilitated cyber-enabled industrial espionage. Security failures explain most of cyber industrial espionage incidents, and insider threats represent a significant pattern in many case examples. Insiders can inadvertently or purposefully pose serious threats to organisations by facilitating ac

Decentralized Massive MIMO Systems: Is There Anything to be Discussed?
Algorithms for Massive MIMO uplink detection are typically based on a centralized approach, by which baseband data from all antenna modules need to be routed to a central node for further processing. In the case of Massive MIMO, where hundreds or thousands of antennas are expected in the base-station, such architecture requires high interconnection bandwidth between antennas and the central node.
Girth Properties of Time-Varying SC-LDPC Convolutional Codes
Time-varying spatially-coupled low-density parity-check convolutional codes (SC-LDPC-CCs) exhibit excellent features, but their representation requires a very large number of parameters. On the other hand, the description of time-invariant SC-LDPC-CCs is very convenient and their error rate performance, though usually worse, is often satisfactory. In this paper we investigate the girth properties

Transformation of the nematode-trapping fungus Arthrobotrys oligospora
The nematode-trapping fungus Arthrobotrys oligospora was transformed to hygromycin resistance using the hygromycin-B phosphotransferase gene from Escherichia coli under the control of various heterologous fungal promoters. Plasmid DNA was introduced into fungal protoplasts by polyethylene glycol/CaCl2 treatment. Transformation frequencies varied between 1-6 transformants per μg DNA. Seven out of 1
Molecular biology : A linkage between microbial ecology, general ecology and organismal biology
The field of microbial ecology has been developing rapidly, largely owing to the introduction of new molecular methods for identifying individuals, species and populations of microorganisms in nature. In contrast to traditional methods, the new ones do not require the isolation and culture of organisms from the environment. With many of the new methods, genotypes and species of microorganisms can
Microbial oxidation of CH4 at high partial pressures in an organic landfill cover soil under different moisture regimes
The uptake and utilization of CH4 at high concentrations (5-18% vol.) and different soil moistures were followed for samples from a landfill cover soil with a high organic matter content. Measurements of the utilization of CH4 and O2, and production of CO2 indicated that the activity of methanotrophic organisms accounted for most of the O2 respiration. At water saturation, CH4 oxidation rates decr
Phylogeny of nematode-trapping fungi based on 18S rDNA sequences
The small subunit (SSU) ribosomal DNA (18S rDNA) from 15 species of nematode-trapping fungi and closely related non-parasitic species were sequenced. Phylogenetic analysis indicated that species within the genera of Arthrobotrys, Dactylaria, Dactylella, Monacrosporium and Duddingtonia formed a monophyletic and isolated clade among an unresolved cluster of apothecial ascomycetes. The phylogenetic p
Methane oxidation in landfill cover soils, as revealed by potential oxidation measurements and phospholipid fatty acid analyses
Landfills account for ca. 10% of the annual global burden of atmospheric methane. Part of the efflux is mitigated by means of biological methane oxidation in the landfill covers. In this study, two types of landfill cover soils (mineral soil and sewage sludge) were compared with respect to methane emissions as well as potential methane oxidation capacity and the PLFA (phospholipid fatty acid) cont
Microbial community-based measurements to estimate heavy metal effects in soil : The use of phospholipid fatty acid patterns and bacterial community tolerance
Microbial community-based measurements to detect effects of heavy metals in soils rely on the premise that metal toxicity exerts a selection pressure, which induces a change in the composition of the community. The phospholipid fatty acid (PLFA) composition gives an integrated picture of all living organisms in the soil, and changes in the PLFA pattern of the soil indicate an altered species compo
Fungal galectins, sequence and specificity of two isolectins from Coprinus cinereus
This article provides evidence for the presence of galectins, previously known as animal lectins, in a fungal species. The important implication of this study is that the galectin gene family could be much older than previously believed. Furthermore, the wide occurrence of galectins increases the possibility of understanding general functions of lectins.
