Capacity of an extension of cover's two-look Gaussian channel

We extend Cover's two-look Gaussian channel to dispersive, linear, time-invariant channels. An arbitrary number of colored, additive, stationary, Gaussian noise/interference sources is considered. Each noise/interference source may cause correlated or uncorrelated components observed by the two looks. The novelty of this work is a capacity formula derived using the asymptotic eigenvalue distributi

Refuge from climate change-related harm: Evaluating the scope of international protection within the Common European Asylum System

Extreme weather events have the potential to cause serious harm and can contribute to displacement. Such events are expected to increase in frequency and/or intensity as a consequence of climate change. It is therefore of concern that there is widely considered to be a protection gap when affected individuals cross an international border. However, apart from a handful of cases in Australia and Ne

Models and Fictions in (Micro-)Economics

How can an argument that is based on assumptions known to be false deliver any insightful conclusions let alone be used for policy recommendations? Over the years, a variety of concerns regarding (micro-)economic modelling and its relevance for real life have been expressed along these lines. Adding to this methodological discussion, I take seriously the recurrent comparison of economic models wit

A study of the stereochemistry and electronic transitions of cyclic and acyclic thioamides by crystallography, spectroscopy and computational methods

Popular Abstract in Swedish En studie av konformationer och elektronövergångar i ett antal rodaniner, ett tiourinämne och ett par ditiokarbamater m.h.a. kristallografi, spectroskopi och datatekniska beräkningsmetoder.Analysis of conformations and electron transitions of 3-(alkyl or aralkyl)-5-(methyl or phenyl)rhodanines with analogues and N,N'-bis[(S)-1-phenylethyl]-thiourea have been performed by X-ray crystallography, 1H NMR, molecular mechanics, ultraviolet spectroscopy and for the chiral rhodanines, enantiomer chromatography and circular dichroism spectroscopy. The magnitude of rotational barriers has bee

Genomic Diversity and Evolution of Parasitism in Nematode-trapping Fungi

Nematode-trapping fungi are soil-living organisms that have the ability to form infection structures, traps to capture nematodes. Many nematode species are parasites on plants and animals, which have resulted in an interest to use the nematode-trapping fungi as biological control agents. In order to understand more about the genomic diversity and evolution of parasitism among these fungi, several

Elemental Analysis on Freeze-Dried Sections of Human Skin: Studies by Electron Microprobe and Particle Induced X-Ray Emission Analysis

The possibility of using the proton microprobe (PMP) in the elemental analysis of dermatological material, under conditions where the spatial resolution can be restricted to a few micrometers, was demonstrated. Comparison with the electron microprobe (EMP) technique using duplicate sections from the same human skin biopsies revealed that the PMP and EMP techniques are complementary and yield close

Atmospheric transport of persistent organic pollutants to aquatic ecosystems

The load of persistent organic pollutants (POPs) is considered high in the Baltic ecosystem. The Baltic Sea spans over 12 latitudes and the regional differences in climate affect the behavior of POPs. Therefore spatial and temporal variability of the concentrations of POPs in air and precipitation within this area has been investgated at 16 (mostly rural) stations around the Baltic Sea between 199

The effect of moisture content of water trapped in wood joints

To predict the service life of a structure, a model where the exposure of a structure is compared to its resistance can be used. Which exposure and resistance parameters that are relevant depend on which materials the structure consist of. This approach, with an exposure and a resistance parameter, is similar to the one used in structural engineering where a load (exposure) is compared to the bear
