With the introduction of market reforms in the public sector, a set of rules becomes applicable to keep governments from distorting competition. This study discusses the impact of three such competition rules on Swedish government – EU rules on State aid and public procurement, as well as the Swedish rules on anti-competitive sales activities. Together they set the conditions for how governments c

The main aim of the study was to optimize the interfacial presentation of a small antigen-a Tn antigen (N-acetylgalactosamine)-for binding to its analyte anti-Tn antibody. Three different methods for the interfacial display of a small glycan are compared here, including two methods based on the immobilization of the Tn antigen on a mixed self-assembled monolayer (SAM) (2D biosensor) and the third

Flying insect predators intercept their aerial prey with deadly precision. New research reveals that a tiny robber fly, with a brain smaller than a pinhead, achieves this using the same visual mechanism that we ourselves employ to catch a passing ball.

Understanding how and why some species become pests, while their relatives remain harmless, might help us control them. A new study looks at how sensory mechanisms evolved in an emerging pest fly species.

Ultrafast extreme-ultraviolet (XUV) and X-ray sources are revolutionizing our ability to follow femtosecond processes with ångström-scale resolution. The next frontier is to simultaneously control the direction, duration and timing of such radiation. Here, we demonstrate a fully functional opto-optical modulator for XUV light, similar to modulators available at infrared (IR) and visible wavelength

This paper examines the effect of risk attitudes on innovation behavior of academic researchers. Specifically, using two alternate measures of self-reported risk attitudes, we test the hypothesis that aversion to risk would negatively affect revelation of information in innovations. Results based on a sample of more than 2500 German researchers across both measures of risk aversion show that, cons

Vitamin K is known for supporting the carboxylation of hepatic coagulation proteins. Levels of proteins induced by vitamin K absence for factor II (PIVKA-II) reflect hypocarboxylated prothrombin and can be used to detect subclinical vitamin K deficiency. The aim of this study was to determine the prevalence of perioperative subclinical vitamin K deficiency among neurosurgical patients using PIVKA-

During the last two centuries, taxation has not only increased dramatically in level and volume; its structure has also changed: from a heavy reliance on customs revenue in the early nineteenth century to a stronger emphasis on income taxation in the twentieth. A common explanation for this development is the spread of democracy, which supposedly increases redistribution and the size of government

Gene therapy is a promising future tool for treatment of Parkinson’s disease (PD) and several different strategies are currently being evaluated. Although many of these strategies have shown promising results in animal models of PD and parkinsonian patients, some have been less effective and caused adverse side effects. A vector system with high specificity and appropriate expression level of the

The important role of fire in regulating vegetation community composition and contributions to emissions of greenhouse gases and aerosols make it a critical component of dynamic global vegetation models and Earth system models. Over 2 decades of development, a wide variety of model structures and mechanisms have been designed and incorporated into global fire models, which have been linked to diff

Nanowires with a GaSb core and an InAs shell (and the inverted structure) are interesting for studies of electron-hole hybridization and interaction effects due to the bulk broken band-gap alignment at the material interface. We have used eight-band k·p theory together with the envelope function approximation to calculate the band structure of such nanowires. For a fixed core radius, as a function

Delayed emission of protons following β decay of neutron deficient nuclei P26 and S27 was investigated at the ACCULINNA separator in the Flerov Laboratory of Nuclear Reactions at Dubna. Ions of interest, identified in flight, were implanted into the active volume of the gaseous optical time projection chamber, which allowed us to record tracks of charged particles emitted in the decay.
