Activity-related breathlessness is the most problematic symptom of chronic obstructive pulmonary disease (COPD), arising from complex interactions between periph- eral pathophysiology (both pulmonary and non-pulmonary) and central perceptual proces- sing. To capture information on the breathlessness experienced by people with COPD, many different instruments exist, which vary in applicability depe

This paper calls for renewed consideration of the way researchsubjects are selected in the study of subcultures. All too often,subcultural researchers limit themselves to the use of one or twoof the orthodox sampling designs, such as ‘conveniencesampling’ (selecting subjects who are readily available) or ‘chainreferral sampling’ (selecting a readily available subject who refersthe researcher to ot

Objectives HPV self-sampling is an option for cervical screening. The aim of this randomised study was to investigate the compliance, prevalence of HPV, and prevalence of severe dysplasia in a vaginal self-sampling group in comparison to cervical samples collected by midwives (control arm). The hypothesis was that there would be no difference between vaginal self-sampling and cervical sampling to

Sugarcane processing roughly generates 54 million tonnes sugarcane bagasse (SCB)/year, making SCB an important material for upgrading to value-added molecules. In this study, an integrated scheme was developed for separating xylan, lignin and cellulose, followed by production of xylo-oligosaccharides (XOS) from SCB. Xylan extraction conditions were screened in: (1) single extractions in NaOH (0.25

Marine viral sequence space is immense and presents a promising resource for the discovery of new enzymes interesting for research and biotechnology. However, bottlenecks in the functional annotation of viral genes and soluble heterologous production of proteins hinder access to downstream characterization, subsequently impeding the discovery process. While commonly utilized for the heterologous e

In this paper, super-resolution imaging is described and evaluated for x-ray tomography and is compared with standard tomography and upscaling during reconstruction. Blurring is minimized due to the negligible point spread of photon counting detectors and an electromagnetically movable micro-focus x-ray spot. Scans are acquired in high and lowmagnification geometry, where the latter is used to min

The coexistence of Mott localized f states with wide conduction and valence bands in f-electron semiconductors results, quite generically, in a complex optical response with the nature of the absorption edge difficult to resolve both experimentally and theoretically. Here, we combine a dynamical mean-field theory approach to localized 4f shells with an improved description of band gaps by a semilo

Aims: Previous studies on major depressive disorder (MDD) among immigrants have reported mixed results. Using data from primary healthcare settings in Sweden, we compared the incidence of MDD among first- and second-generation immigrants aged 15–39 years with natives. Methods: This was a retrospective nationwide open cohort study. Eligible individuals were born 1965–1983, aged 15–39 years at basel

The Ukrainian Shield and Voronezh Crystalline Massif constitute the Sarmatian segment of Baltica. Here, only a few mafic-ultramafic dykes and layered intrusions have been dated, recording early Statherian (ca. 1800–1750 Ma) ages. We have determined new U-Pb baddeleyite ages for the Novogol sill (1789 ± 2 Ma) and the Gremyachye intrusion (1781 ± 7 Ma), which fall within the previously established a

The 1974 Instrument of Government forms the core of Swedish constitutional law. It replaced its partly defunct predecessor of 1809 and scrapped the separation of powers between King and Riksdag that characterised the previous constitutional system. By abolishing the formal power of the King in Council (Kungl. Maj:t, “Royal Majesty”), it aimed at establishing a modern written constitution, which la

Ultrafast, light-induced dynamics in copper-zinc-tin-sulfide (CZTS) photovoltaic nanoparticles are investigated through a combination of optical and x-ray transient absorption spectroscopy. Laser-pump, x-ray-probe spectroscopy on a colloidal CZTS nanoparticle ink yields element-specificity, which reveals a rapid photo-induced shift of electron density away from Cu-sites, affecting the molecular or

In-cycle closed-loop combustion control has been proved to reduce cycle-to-cycle variations on emissions and indicated thermal efficiency. In this paper, the in-cycle closed-loop combustion con-trollability achieved by a pilot-main fuel injection scheme is investigated. The controllability is studied by means of the maximum reachable indicated thermal efficiency (MRE). A combustion model is used f

Background: Obesity prevalence is increasing globally. Bariatric surgery is an effective treatment for severe and complex obesity resulting in significant and sustained weight loss. In Sweden, most bariatric surgery patients are referred by primary care physicians. We aimed to explore barriers for physicians to refer patients with severe and complex obesity for bariatric surgery. Methods: A questi

Fiji is a Small Island Developing State (SIDS) in the Pacific Ocean, with relatively population mobility. In this context, we study the individual-level characteristics of Fijian internal migration. Hence, our contribution lies in investigating migrant selectivity and differences in migratory behavior of different subgroups of the Fijian population. Specifically, we focus on factors such as gender

Two-particle angular correlations are measured in high-multiplicity proton-proton collisions at s = 13 TeV by the ALICE Collaboration. The yields of particle pairs at short-(∆η ∼ 0) and long-range (1.6 < |∆η| < 1.8) in pseudorapidity are extracted on the near-side (∆φ ∼ 0). They are reported as a function of transverse momentum (pT) in the range 1 < pT< 4 GeV/c. Furthermore, the event-scale depend
