It is a long-standing view that the main mechanism maintaining narrow migratory divides in passerines is the selection against intermediate and suboptimal migratory direction, but empirical proof of this is still lacking. We present novel results from a willow warbler migratory divide in central Sweden from where birds take the typical SW and SE as well as intermediate routes to winter quarters in
Microbiomes play an important role in determining the ecology and behaviour of their hosts. However, questions remain pertaining to how host genetics shape microbiomes, and how microbiome composition influences host fitness. We explored the effects of geography, evolutionary history and host genetics on the skin microbiome diversity and structure in a widespread amphibian. More specifically, we ex
Immune thrombocytopenia (ITP) is characterized by a dysregulated immune response against platelets, affecting both their destruction and production. A role for an abnormal T-cell compartment has been established in ITP pathogenesis and treatments that increase platelet counts in patients with ITP have shown improvements in T-cell profiles. On the other hand, patients who were refractory to treatme
Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory joint disease that affects all aspects of life. Rheumatology care strives to achieve optimal health based on person-centred care (PCC). Effective treatment is available, but patients still experience unmet needs.Aims: The overall aim of this thesis was to explore patients' perspectives of PCC and preferred outcomes in early RA. Specifi
The advent of 6G wireless communication marks a transformative era in technological connectivity, bringing forth challenges and opportunities alike. This paper unveils an innovative, open-source simulator, meticulously crafted for cell-free 6G wireless networks. This simulator is not just a tool but a gateway to the future, blending cutting-edge channel models with the simulation of both physical
Purpose: Reablement is a multidisciplinary intervention aimed at promoting function and independence for people with functional decline. Detailed descriptions of various professions’ actions are needed for organization and evaluation of reablement services. This study describes physiotherapy practice in a reablement context in Swedish municipalities, focusing on the content and magnitude of interv
Objectives: To define requirements that condition trust in artificial intelligence (AI) as clinical decision support in radiology from the perspective of various stakeholders and to explore ways to fulfil these requirements. Methods: Semi-structured interviews were conducted with twenty-five respondents—nineteen directly involved in the development, implementation, or use of AI applications in rad
This paper proposes a motion control scheme for robots operating in a dynamic environment with concave obstacles. A Model Predictive Controller (MPC) is constructed to drive the robot towards a goal position while ensuring collision avoidance without direct use of obstacle information in the optimization problem. This is achieved by guaranteeing tracking performance of an appropriately designed re
Nanowire growth in the standard < 111 > direction is assumed to occur at a planar catalyst-nanowire interface, but recent reports contradict this picture. Here we show that a nonplanar growth interface is, in fact, a general phenomenon. Both III-V and group IV nanowires show a distinct region at the trijunction with a different orientation whose size oscillates during growth, synchronized with ste
Climate changes have profound effects on the distribution of numerous plant and animal species(1-3). However, whether and how different taxonomic groups are able to track climate changes at large spatial scales is still unclear. Here, we measure and compare the climatic debt accumulated by bird and butterfly communities at a European scale over two decades (1990-2008). We quantified the yearly cha
Objectives: To investigate whether KALRN gene variation is associated with ischemic stroke (IS). Design and methods: Associations to overall IS and IS subtypes were investigated in SAHLSIS, which comprises 844 patients with IS and 668 controls. Results: Associations between KALRN SNPs and overall IS and cardioembolic stroke were detected. Associations for overall IS were investigated in two additi
Context:Obesity and insulin resistance are risk factors for cancer development. The IRS1 rs2943641 genetic variant has been widely associated with insulin resistance.Objective:The aim of the study was to examine whether the IRS1 rs2943641 associates with cancer incidence in obese individuals.Design, Setting and Patients:The IRS1 rs2943641 was genotyped in participants from the Swedish Obese Subjec
It is well-documented that male overweight and obesity causes endocrine disorders that might diminish the male reproductive capacity; however, reports have been conflicting regarding the influence of male body mass index (BMI) on semen quality and the outcome of assisted reproductive technology (ART). The aim of this study was to investigate whether increased male BMI affects sperm quality and the
Thermal degradation of poly[(R)−3-hydroxybutyric acid] (PHB) during melt mixing results in random chain scission that produces shorter polymer chains containing crotonic and carboxyl end groups. One way of preventing this serious reduction of molar mass is to add agents that react with at least two of the newly generated end groups. Different types of commercially available additives known to reac
Aim. This article is a report of a study of how healthcare professionals involved in surgery orientate themselves to their common task, and how this orientation can be affected by the social and organizational context. Background. Previous research indicates that surgical teams are not as cohesive as could be expected and that communication failures frequently occur. However, little is known abo
Streptococcus pyogenes is a major human bacterial pathogen responsible for severe and invasive disease associated with high mortality rates. The bacterium interacts with several human blood plasma proteins and clarifying these interactions and their biological consequences will help to explain the progression from mild to severe infections. In this study, we used a combination of mass spectrometry
COPHES/DEMOCOPHES has its origins in the European Environment and Health Action Plan of 2004 to "develop a coherent approach on human biomonitoring (HBM) in Europe". Within this twin-project it was targeted to collect specimens from 120 mother-child-pairs in each of the 17 participating European countries. These specimens were investigated for six biomarkers (mercury in hair; creatinine, cotinine,
Stanley Micklavzina, a US physics educator on sabbatical, teams up with a Swedish national research laboratory, a synchrotron radiation experimental group and a university science centre to develop and create educational and public outreach projects. Descriptions of the physics, science centre displays and public demonstrations covering the physics principles involved in using photons and neutrons
Previous research on violence during the war in Bosnia and Herzegovina has resulted in a one-sided presentation of the phenomenon of “war violence.” Researchers have emphasized the importance of narratives in general but have not analyzed stories on war violence that were the product of interpersonal interaction and meaning-making activity. The aim of this article is to fill this knowledge gap by
