Does a prior diagnosis of infectious disease confer an increased risk of latent autoimmune diabetes in adults?

Aims: Infections are proposed risk factors for type 1 diabetes in children. We examined whether a diagnosis of infectious disease also confers an increased risk of latent autoimmune diabetes in adults (LADA). Materials and methods: We used data from a population-based Swedish case-control study with incident cases of LADA (n = 597) and matched controls (n = 2386). The history of infectious disease

Semiclassical analysis of a nonlocal boundary value problem related to magnitude

We study a Dirichlet boundary problem related to the fractional Laplacian in a manifold. Its variational formulation arises in the study of magnitude, an invariant of compact metric spaces given by the reciprocal of the ground state energy. Using recent techniques developed for pseudodifferential boundary problems we discuss the structure of the solution operator and resulting properties of the ma

Harnessing cognitive trajectory clusterings to examine subclinical decline risk factors

Cognitive decline in Alzheimer's disease and other dementias typically begins long before clinical impairment. Identifying people experiencing subclinical decline may facilitate earlier intervention. This study developed cognitive trajectory clusters using longitudinally based random slope and change point parameter estimates from a Preclinical Alzheimer's disease Cognitive Composite and examined

The Sovereign Human Being : Carl Schmitt, Dietrich Bonhoeffer and Responsible Decision-Making

Sovereign is who decides; and who decides is responsible. The book develops these two arguments by comparing Carl Schmitt's and Dietrich Bonhoeffer's theories of sovereignty.Carl Schmitt was an influential jurist of Nazi Germany. Dietrich Bonhoeffer was a Lutheran priest hanged for his involvement in a plot to assassinate Adolf Hitler. In many ways, the two men could not be more different. But the

Discussion Seminars – an Award-winning Pedagogical Method

There are many pedagogical methods to engage students in active learning. This paper presents Discussion Seminars, which is one such method that is much appreciated by students. This paper explains how to structure seminars and discusses their benefits and what requirements they put on the teacher. The paper aims to inspire other teachers to try something similar.

Advanced Diffusion-Weighted MRI for Cancer Microstructure Assessment in Body Imaging, and Its Relationship With Histology

Diffusion-weighted magnetic resonance imaging (DW-MRI) aims to disentangle multiple biological signal sources in each imaging voxel, enabling the computation of innovative maps of tissue microstructure. DW-MRI model development has been dominated by brain applications. More recently, advanced methods with high fidelity to histology are gaining momentum in other contexts, for example, in oncologica

Redemption Through Play? Exploring the Ethics of Workplace Gamification

Today, it is becoming increasingly common for companies to harness the spirit of play in order to increase worker engagement and improve organizational performance. This paper examines the ethics of play in a business context, focusing specifically on the phenomenon of workplace gamification. While critics highlight ethical problems with gamification, they also advocate for more positive, transfor

Efficient BiSAR PFA Wavefront Curvature Compensation for Arbitrary Radar Flight Trajectories

The polar format algorithm (PFA) is a popular choice for general bistatic synthetic aperture radar (BiSAR) imaging due to its computational efficiency and adaptability to situations with complicated geometries or arbitrary flight trajectories. However, efficient and accurate compensation of 2-D residual phase errors induced by the wavefront curvature remains challenging when obtaining high-quality

On Calibration Algorithms for Real-Time Brain-Computer Interfaces

A Brain-Computer Interface (BCI) is a system that, in real-time, translates the user's brain activity into commands that can be used to control applications, such as moving a cursor on the screen. The translation is made possible by machine learning methods and other algorithms. The thesis focuses on EEG-based BCIs which are the most common type of BCIs due to EEG measurements being non-invasive,

Dynamic Behavior of Tin at Platinum Surfaces during Catalytic CO Oxidation

Platinum-tin surfaces are active for CO oxidation, but their activity and the effects of tin oxide phases that form under reaction conditions are poorly understood. We have studied surface alloys of tin prepared on platinum single crystals during catalytic CO oxidation using near-ambient-pressure X-ray photoemission spectroscopy. On the flat terraces of Sn/Pt(111), a wetting layer of Sn(II) surfac

Efficacy and safety of SBRT for spine metastases : A systematic review and meta-analysis for preparation of an ESTRO practice guideline

Background and purpose: Advances in characterizing cancer biology and the growing availability of novel targeted agents and immune therapeutics have significantly changed the prognosis of many patients with metastatic disease. Palliative radiotherapy needs to adapt to these developments. In this study, we summarize the available evidence for stereotactic body radiotherapy (SBRT) in the treatment o

Airway contraction and cytokine release in isolated rat lungs induced by wear particles from the road and tire interface and road vehicle brakes

The dominant road traffic particle sources are wear particles from the road and tire interface, and from vehicle brake pads. The aim of this work was to investigate the effect of road and brake wear particles on pulmonary function and biomarkers in isolated perfused rat lungs. Particles were sampled from the studded tire wear of three road pavements containing different rock materials in a road si

From flesh to paper : Bodily and material transformation in seventeenth-century Copenhagen-a case-study

This article investigates the transformation of the body of a female child murderer as she passed through specific spatial configurations in the urban setting of the seventeenth-century capital of Denmark-Norway. By using the case of Gertrud Nielsdatter, we explore the significance of public urban spaces in the bodily and material transformation of a woman from a condemned sinner to an object of s

Educational attainment in survivors of childhood cancer in Denmark, Finland, and Sweden

Background: Survivors of childhood cancer may face difficulties at school. We investigated whether childhood cancer affects attainment of upper secondary education, in a register-based cohort study from Denmark, Finland, and Sweden, where we limit bias from selection and participation. Methods: From the national cancer registers, we identified all long-term survivors of childhood cancer diagnosed

EUFOREA/EPOS2020 statement on the clinical considerations for CRSwNP care

Following the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) treatment algorithm for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), patients suffering from severe uncontrolled CRSwNP are recommended to receive oral corticosteroids, (revision) sinus surgery, systemic biologicals and/or aspirin treatment after desensitization (ATAD). Given the major diff
