To investigate differences and similarities in person-environment (P-E) fit problems between very old people with self-reported Parkinson's disease (PD) and matched controls.

The performance of InGaAs metal oxide semiconductor field effect transistors with Al2O3 or HfO2 as gate oxide is evaluated and compared. The Al2O3 transistors show the lowest subthreshold slope and mid gap D-it, however, the HfO2 transistors reach a higher maximum transconductance (g(max)) due to the higher oxide capacitance. Both high-kappa dielectrics show a g(m)-frequency dispersion due to tunn

Injection drug users (IDUs) are at increased risk of various medical conditions, including bacterial skin and soft tissue infections (SSTIs). SSTIs, which are painful and can lead to life-threatening complications, are common but scarcely studied.

We study the few-body physics of trapped atoms or molecules with electric or magnetic dipole moments aligned by an external field. Using exact numerical diagonalization appropriate for the strongly correlated regime, as well as a classical analysis, we show how Wigner localization emerges with increasing coupling strength. The Wigner states exhibit nontrivial geometries due to the anisotropy of th

In this study, we assessed the performance of discharge simulations by coupling the runoff from seven Dynamic Global Vegetation Models (DGVMs; LPJ, ORCHIDEE, Sheffield-DGVM, TRIFFID, LPJ-GUESS, CLM4CN, and OCN) to one river routing model for 16 large river basins. The results show that the seasonal cycle of river discharge is generally modeled well in the low and middle latitudes but not in the hi

The underlying mechanisms behind the obstetric condition pre-eclampsia (PE) are still unclear. Manifestation of PE is heterogeneous and it has therefore been proposed to be a syndrome with different causes rather than one disease with a specific aetiology. Recently, we showed differences in circulating angiogenic factors between two subgroupsearly- and late-onset PE. To further elucidate the diffe

For several reinforcement learning models in strategic-form games, convergence to action profiles that are not Nash equilibria may occur with positive probability under certain conditions on the payoff function. In this paper, we explore how an alternative reinforcement learning model, where the strategy of each agent is perturbed by a strategy-dependent perturbation (or mutations) function, may e

This paper presents the archaeological prospection, excavation and digital three-dimensional documentation of a previously unknown neolithic grave, presumably late neolithic, at the outstanding Iron Age site of Uppåkra in southern Sweden, and exemplifies a multidisciplinary approach to modern archaeological fieldwork. In the framework of a large-scale archaeological prospection pilot study conduct

Most hovering animals, such as insects and hummingbirds, enhance lift by producing leading edge vortices (LEVs) and by using both the downstroke and upstroke for lift production. By contrast, most hovering passerine birds primarily use the downstroke to generate lift. To compensate for the nearly inactive upstroke, weight support during the downstroke needs to be relatively higher in passerines wh

We show that gels formed by arrested spinodal decomposition of protein solutions exhibit elastic properties in two distinct frequency domains, both elastic moduli exhibiting a remarkably strong dependence on volume fraction. Considering the large difference between the protein size and the characteristic length of the network we model the gels as porous media and show that the high and low frequen

The environmental impact of an extended property close source-separation system for solid household waste (i.e. a systems for collection of recyclables from domestic properties) is investigated in a residential area in southern Sweden. Since 2001, households have been able to source-separate waste into six fractions of dry recyclables and food waste sorting. The current system was evaluated using

This study describes the prevalence of adverse events and length of stay in forensic psychiatric patients with and without a restriction order. Detailed clinical and administrative information from medical records and written court decisions was gathered retrospectively from admission until discharge for a Swedish population-based, consecutive cohort of forensic psychiatric patients (n=125). The m

Skeletal muscle weakness is a prominent clinical feature in patients with rheumatoid arthritis (RA), but the underlying mechanism(s) is unknown. Here we investigate the mechanisms behind arthritis-induced skeletal muscle weakness with special focus on the role of nitrosative stress on intracellular Ca(2+) handling and specific force production.

The aim of perioperative antibiotic prophylaxis is the prevention of surgical site infections and urinary tract infections during urological procedures. The indication for antibiotic prophylaxis comprises several risk factors such as the degree of contamination of the operative site, duration of surgery, implantation of devices and comorbidities of the individual patient. In general this involves

Of the 287 000 maternal deaths every year, 99% happen in low- and middle-income countries. The vast majority could be averted with timely access to appropriate emergency obstetric care (EmOC). The proportion of women with complications of pregnancy or childbirth who actually receive treatment is reported as 'Met need for EmOC'.
