Objectives To determine the incidence rate (IR) and predictors of myocardial infarction (MI) in patients with antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) as well as to estimate the IR ratio (IRR) of MI in AAV versus the background population. Methods 325 patients diagnosed with AAV 1997-2016 in Skåne, Sweden were included. Data were collected from the time of AAV dia
Heterogeneous integration of III-V narrow bandgap transistors on silicon technology is desirable for high frequency circuit implementations. Such high-speed transistors must, however, scale to large gate widths to be suitable for general circuit design. Averaging among many variable channels is a key challenge for nanowire devices. A simplified, but high-speed compatible, nanowire device process w
We review concepts and recent work related to creating light-matter interfaces for future quantum networks based on rare-earth ion-doped crystals. More precisely, we explore their unique suitability for creating photon sources, optical quantum memories for light, and qubits that allow quantum information processing. In addition, we review the state-of-the-art of elementary quantum repeater links,
Three new cobalt complexes of the general formula [Co(II)(L)(CH3CN)]2+, where L is one of three pentadentate nitrogen-donor ligands based on the N4Py framework, have been synthesized and characterized. The capacity of the three complexes to effect photocatalytic proton reduction has been examined. Their photocatalytic activities in the presence of [Ru(bpy)3]2+, acting as a photosensitizer, and asc
Cryogenic land surface processes (CLSPs), such as cryoturbation, are currently active in landscapes covering 25% of our planet where they dictate key functions, such as carbon (C) cycling, and maintain patterned landscape features. While CLSPs are expected to diminish in the near future due to milder winters especially in the southern parts of the Arctic, the shifts in C cycling in these landscape
Purpose: The purpose is to describe the Malmö Breast Tomosynthesis Screening Project from the beginning to where we are now, and thoughts for the future. Approach: In two acts, we describe the efforts made by our research group to improve breast cancer screening by introducing digital breast tomosynthesis (DBT), all the way from initial studies to a large prospective population-based screening tri
Operando resonant photoelectron spectroscopy (RPES) combined with modulated chemical excitation revealed the dynamic evolution of Ce3+/Ce4+ redox states at the surface of CeO2 during the CO oxidation reaction. Using alternating CO and O2 pulses as chemically modulated signals, we monitored the surface states in the valence band region, unveiling the evolution of electronic structure during the cat
Purpose: To achieve the high sensitivity of digital breast tomosynthesis (DBT), a time-consuming reading is necessary. However, synthetic mammography (SM) images, equivalent to digital mammography (DM), can be generated from DBT images. SM is faster to read and might be sufficient in many cases. We investigate using artificial intelligence (AI) to stratify examinations into reading of either SM or
OBJECTIVES: To describe the prevalence of cardiovascular disease (CVD) at the time of diagnosis of adult-onset type 1 (T1D) and type 2 (T2D) diabetes, in a recent cohort and compare to a previous cohort from the same region. Further, to explore factors influencing the prevalence of pre-existing CVD, including age, sex, body mass index (BMI) and C-peptide; in the later cohort also heart failure, hy
Apolipoprotein E4 (ApoE4), the major genetic risk factor for Alzheimer's disease (AD), is vital for understanding cellular processes involved in AD pathogenesis. Evidence implicates endosomes as a central player in AD, where endosomal enlargement in neurons is among the earliest changes in AD. This enlargement was reported to be enhanced in APOE4 carriers. Cells internalize ApoE into endosomes for
This paper examines how the concept ‘nature-positive’ as a means to enhance biodiversity is defined and used, viewed through the lens of power. Building on a three-dimensional conceptualization of power, we elaborate on i) how ‘nature-positive’ enters and remains on business and policy agendas, ii) different interpretations from both ecological and business perspectives, and iii) the governance of
PURPOSE: Given the paucity of data regarding workplace risk of COVID-19, particularly from countries with limited lockdowns, we aimed to quantify the occupational risks of COVID-19-related hospital admission among workers in Sweden.METHODS: We identified 607,179 employed individuals, 20-69 years of age, in Skåne, Sweden. From December 31st, 2019-December 31st 2021, 2,633 incident COVID-19-related
III-Nitride high-electron mobility transistors (HEMTs) grown on AlN substrates offer significant advantages for high-power, high-frequency applications due to AlN high thermal conductivity and ultra-wide bandgap. However, achieving high-quality thin GaN channel layers on AlN is challenging because of lattice mismatch, which leads to columnar growth. In this work, we present the development of a tw
The ongoing climate change has been increasingly reflected in climate observations around the world, both in terms of averages and extremes, and attributed to anthropogenic climate forcing. When it comes to changing extremes, attribution to climate change is now especially well-established for heat-related extremes worldwide. Understanding changes in extremes is important for climate adaptation as
State-of-the-art laser frequency stabilization is limited by miniscule length changes caused by thermal noise. In this work, a cavity-length-insensitive frequency stabilization scheme is implemented using strong dispersion in a 21 mm long cavity with a europium-ion-doped spacer of yttrium orthosilicate. A number of limiting factors for slow light laser stabilization are evaluated, including the in
This chapter provides a brief yet comprehensive overview of the state-of-the-art in semiconductor characterization using spectroscopic ellipsometry. The concept of ellipsometry as optical technique to determine the state of polarization of light reflected or transmitted from complex-structured and multiple layered semiconductor materials is introduced and laid out in the framework of the Jones vec
Electron paramagnetic resonance of Cr3+ ions in β -Ga2O3 is investigated using terahertz spectroscopic ellipsometry under magnetic field sweeping, a technique that enables the polarization resolving capabilities of ellipsometry for magnetic resonance measurements. We employed a single-crystal chromium-doped β -Ga2O3 sample, grown by the Czochralski method, and performed ellipsometry measurements a
X-ray fluorescence emission spectroscopy is a powerful tool to gain chemical information on a wide variety of samples. Its combination with focused X-ray beams and translation stages enables X-ray fluorescence microscopy, generating quantitative distribution maps for sets of chemical elements, depending on incident photon energy and detector specifications. The use of synchrotron radiation for X-r
We present an operando study where Ambient-Pressure X-ray Photoelectron Spectroscopy (AP-XPS), Polarization Modulation-InfraRed Reflection Absorption Spectroscopy (PM-IRRAS) and Mass Spectrometry (MS) were employed simultaneously with sub-minute time resolution to monitor the CO oxidation and NO reduction reactions on Rh(111). AP-XPS is a powerful tool to follow reactions at the surface-gas interf
