Background: Respiratory symptoms are common in the general adult population. Increased burden of respiratory symptoms may increase the risk of mortality. We assessed the association between respiratory symptom clusters and mortality. Methods: Participants were derived from two population-based Swedish adult cohorts (N = 63,060). Cluster analysis was performed with Locality Sensitive Hashing (LSH)-

This paper proposes an alternative semi-analytical Fourier modal method adapted for general periodic anisotropic gratings made of dielectrics with moderate to low index profiles corresponding to materials ranging from conventional dielectric 3D printing materials to ceramic materials. The proposed method is closely related to classical Rigorous Coupled-Wave Analysis built on scattering matrices, h

Serial crystallography (SX) at both X-ray free-electron lasers (XFELs) and synchrotrons offers the possibility to collect data at non-cryogenic temperature almost radiation damage free and enables time-resolved crystallography of irreversible reactions. The necessary steady delivery of new micron-sized crystals of biological macromolecules sets it apart from traditional single crystal macromolecul

ObjectiveRecent studies suggest that immigrants trade youth when partnering with members of the White majority population. This study contributes to this emerging literature by examining whether this trade should be understood as differential treatment based on immigrant status or as a broader dynamic of racial preferences in the marriage market.MethodsThis study compares age gaps in unions of int

This study investigates the ignitability of hydrogen in an optical heavy-duty SI engine. While the ignition energy of hydrogen is exceptionally low, the high load and lean mixtures used in heavy-duty hydrogen engines lead to a high gas density, resulting in a much higher breakdown voltage than in light-duty SI engines. Spark plug wear is a concern, so there is a need to minimise the spark energy w

We propose a dynamical model depicting nitrogen (N2) fixation (diazotrophy) in a unicellular cyanobacterium, Crocosphaera watsonii, grown under light limitation and obligate diazotrophy. In this model, intracellular carbon and nitrogen are both divided into a structual pool and a storage pool. An internal pool that explicitly describes the nitrogenase enzyme is also added. The model is successfull

I en svår tid kan ett enkelt digitalt upplägg innebära både glädje och lättnad för många människor. Det skriver forskarna Tove Harnett, Sofi Fristedt och Håkan Jönson tillsammans med Eva Wiman, anhörigrådgivare och verksamhetsansvarig vid Malmö anhörigförening.

This volume highlights the intricate relationship between religion, migration, and policy-making. It does so by investigating matters in different corners of Europe, from Iceland in the north to Spain in the south. With a clear focus on minority religions on the one hand and how Christianity is used to construct a European identity on the other, the authors provide insights into how different reli

Renin from plasma, kidney, and recombinant sources was previously demonstrated to cleave C3 to C3a and C3b. C3a was generated at a similar rate to that by C3 convertase, and C3 cleavage was inhibited by the renin inhibitor aliskiren. Renin endogenously produced by Calu6 cells also led to C3 deposition on cells. These results have been challenged by another group suggesting that recombinant renin d

Defaulter tracing policies for Prevention of Mother-to-Child Transmission (PMTCT) services are vital for achieving the global goal of zero new HIV infections. However, little is known about their implementation. This qualitative study explores the role of tracers—community volunteers, retention workers, and mentor mothers—in implementing such policy across six facilities in Western Kenya.
