We show that the problem of constructing a minimum directed Steiner tree of depth O(log(d)n) in a directed graph of maximum outdegree d admits an expO(root logn)-approximation in polynomial time.

The article investigates translation culture in the Swedish dominion Swedish Pomerania during the eighteenth century, with a particular focus on periodicals.

Three kinds of light emission are taking place from organisms: bioluminescence in a narrow sense from some animals, dinoflagellatees, fungi and bacteria; delayed light emission from photosynthetic cells; ultraweak light emission from all kinds of cells. All these phenomena are treated in this chapter.

This paper presents the incorporation of an auto-tuning real-time garbage collector into a feedback-based on-line scheduling system. The studied feedback scheduler is designed to dynamically adjust the sampling periods of a set of controller tasks in order to maximize the overall control performance. In the suggested approach, the memory management overhead is made explicit and taken into account

We address the question of which syntactic representation is best suited for role-semantic analysis of English in the FrameNet paradigm. We compare systems based on dependencies and constituents, and a dependency syntax with a rich set of grammatical functions with one with a smaller set. Our experiments show that dependency-based and constituent-based analyzers give roughly equivalent performance

The Swedish county council Region Skane is developing work processes for iterative risk and vulnerability analyses. This will be arranged in a distributed bottom-up manner, where analyses are performed and results reported through three hierarchical levels, ending at a central unit within the county council organisation. That unit is responsible for three tasks: 1) Establish a summary of the risks

In this special issue of the Journal of Environment and Development, we present results from the research project Globalisation Informed by Sustainable Development (GLOBIS), 2009-2014, funded by the European Union Framework Programme 7. Starting from and focusing on international policies on agriculture, energy, innovation, migration, and transport at both European Union and global levels, the dua

Infections in cystic fibrosis (CF), often involving Pseudomonas aeruginosa, result from a dysregulated airway immunity where one hallmark is the accumulation of necrotic and apoptotic immune cells, in particular neutrophils. In addition, neutrophils actively release DNA, forming neutrophil extracellular traps (NETs) that contain antimicrobial proteins. Altogether, free DNA in complex with actin ac

Two-photon laser-induced fluorescence for detection of carbon monoxide (CO) frequently shows interferences by emission from photolytically produced C-2 radicals encountered under fuel-rich combustion conditions. Reduced C-2 interference for excitation with laser pulses in the picosecond regime is here demonstrated by comparison with excitation using nanosecond pulses for measurements in laminar pr

Chronic pulmonary disease is a recognized risk factor for invasive pneumococcal disease (IPD). However, previous studies have often not been large enough to allow detailed analyses of less prevalent pulmonary diseases, and findings regarding case fatality have been inconsistent. We examined the associations between an underlying pulmonary disease and IPD, and the impact of these diseases on the ca

Copper, zinc superoxide dismutase 1 (SOD1) is a ubiquitous homodimeric enzyme, whose misfolding and aggregation play a potentially key role in the neurodegenerative disease amyotrophic lateral sclerosis (ALS). SOD1 aggregation is thought to be preceded by dimer dissociation and metal loss, but the mechanisms by which the metal-free monomer aggregates remain incompletely understood. Here we use imp

In the course of a long-term radial velocity survey of about 100 southern pre-main-sequence (PMS) stars, we have discovered two spectroscopic PMS binaries. One is the weak-lined T Tauri star Haro 1-14c in the Ophiuchus clouds, which has a spectral type of K3 and is a member of the visual Haro 1-14 binary with a separation of 12."9. Haro 1-14c is a single-lined spectroscopic binary with a very long
