The demand for fast and energy efficient (opto-)electronic applications needs high mobility semiconductor materials, such as InAs with a very high electron mobility and GaSb with a very high hole mobility. Beyond the material itself, also an innovative device geometry is needed, for example, the gate-all-around geometry that provides higher efficiency and electrostatic control for computational un
The chemical composition of non-refractory submicron aerosol (NR-PM1) was characterized at the Villum Research Station (Villum) at Station Nord in North Greenland during spring-summer 2016 using a Time of Flight Aerosol Chemical Speciation Monitor (ToF-ACSM). The composition is dominated by sulfate (48%) and organic species (40%). Positive Matrix Factorization (PMF) identified three key factors co
Background: Emergency surgery for acute type A aortic dissection in patients with previous cardiac surgery is controversial. This study aimed to evaluate the association between previous cardiac surgery and outcomes after surgery for acute type A aortic dissection, to appreciate whether emergency surgery can be offered with acceptable risks. Methods: All patients operated on for acute type A aorti
Background: European treatment guidelines recommend prasugrel over ticagrelor for treating patients with non–ST-elevation acute coronary syndrome (ACS), prompting several Swedish administrative regions to transition from ticagrelor to prasugrel as the preferred treatment for patients with ACS. We aim to systematically evaluate this transition to determine the relative efficacy of prasugrel versus
We developed models for individualized risk prediction of cognitive decline in mild cognitive impairment (MCI) using plasma biomarkers of β-amyloid (Aβ), tau and neurodegeneration. A total of 573 patients with MCI from the Swedish BioFINDER study and the Alzheimer’s Disease Neuroimaging Initiative (ADNI) were included in the study. The primary outcomes were longitudinal cognition and conversion to
Context: Growth hormone (GH) is used to treat short children born small for gestational age (SGA); however, the effects of treatment on pubertal timing and adult height are rarely studied. Objective: To evaluate adult height and peak height velocity in short GH-treated SGA children. Methods: Prospective longitudinal multicenter study. Participants were short children born SGA treated with GH thera
Self-assembly and fibril formation play important roles in protein behaviour. Amyloid fibril formation is well-studied due to its role in neurodegenerative diseases and characterized by refolding of the protein into predominantly β-sheet form. However, much less is known about the assembly of proteins into other types of supramolecular structures. Using cryo-electron microscopy at a resolution of
Phytochemicals have been used as one of the sources for the development of anti-obesity drugs. Plants are rich in a variety of bioactive compounds including polyphenols, saponins and terpenes. Phytochemicals inhibit adipocyte differentiation by inhibiting the transcription and translation of adipogenesis transcription factors such as C/EBPα and PPARγ. It has been proved that phytochemicals inhibit
Complete 4F2 vertical nanowire (VNW) 1T1R cells with 106 cycles switching endurance and with a demonstrated capability of performing Boolean logic are fabricated and characterized in cross-point arrays. The performance of the vertical 1T1R cell is benefited from using the same III-V/high- k interface both for the vertical GAA MOSFET selector as well as the ReRAM. In this paper, we also compare the
In the last decade a number of women-led mosques have emerged in Europe and North America. In The Making of a Mosque with Female Imams Jesper Petersen documents the serendipitous, yet predictable, emergence of the Mariam Mosque in Copenhagen. The study first demonstrates that individuals’ facing the unpredictable plays a decisive role in social processes. This leads to an investigation of how sere
We propose a consensus definition of "an exaggerated orthostatic pressor response" in subjects in whom systolic blood pressure increases ≥ 20 mmHg when going from supine to standing posture. This definition can be extended for seated to standing measurements. We reserve the term "orthostatic hypertension" for when this pressor response leads to an upright systolic blood pressure ≥ 140 mmHg. We bel
AIMS: This study aims to determine the familial incidence of dilated (DCM) and hypertrophic cardiomyopathy (HCM) in first-degree, second-degree, and third-degree relatives of affected individuals.METHODS AND RESULTS: In this population-based multigenerational cohort study, full-siblings, half-siblings, and cousin pairs born to Swedish parents between 1932 and 2015 were included, and register-based
The city of Copenhagen, often celebrated as one of the world’s greenest for its cycling culture and other initiatives, recently defaulted on its pledge to become carbon-neutral by 2025. This early failure in the global race to net zero emissions (a balance between CO₂ emitted and absorbed) may foreshadow backtracking by other target-setters, indicating that pledges to cease contributing to climate
This study provides a cross-platform, longitudinal investigation of pictures depicting political candidates posted to Facebook and Instagram over a 15-month period during the 2020 US election(n = 4,977). After motivating an exploratory research design, we set out to expound: the extent of cross-platform image posting across Facebook and Instagram; the emotion expression of politicians across the t
Recreational hunting in Sweden can be depicted as being embedded in two different but overlapping cultural and socio-economic contexts. One is the traditional stewardship-oriented form of hunting, in Swedish called ‘allmoge’ hunting. Another form is the commercial form of hunting, where hunting is packaged and offered to visitors, quite often with different types of services included. These two fo
Spectra emitted from laser-produced plasmas of scandium, titanium, vanadium and chromium have been recorded in the region 270-600 Å, and lines belonging to the 3s-3p and 3p-3d transition arrays in neonlike ions have been identified. The 2p53s, 3p and 3d energy levels have been derived from the observations for Ti XIII and from solar flare lines for Fe XVII. Hartree-Fock calculations and parametric
The gallium spectrum emitted from a hollow cathode has been recorded in the region 500-9800 A. 142 lines have been classified as transitions in Ga II. Energy levels have been derived from the observations, and perturbations within the n = 4 configuration complex are discussed. Besides the previously known mixing between 4s4d and 4p2, it has been found that the structure of 4s4/is strongly affected
Average energies for the configurations 2p5 3s, 3p and 3d in a number of neon-like ions from Al IV to Xe XLV have been calculated by means of the MCDF computer code of Grant et al. The results have been compared with observations and previous non-relativistic calculations. Fine- structure levels and 3s-3p and ip-3d transition wavelengths have also been calculated with the MCDF code for Ti XIII and
Results from the radiological environmental monitoring of the European Spallation Source (ESS) are presented for 2021. Previous zero-point assessments (2017-2020) have mainly focussed on terrestrial samples. New sample types for 2021 include a sediment sample from a pond at the ESS and brown seaweed (Fucus) from Lomma bay and from the east coast of Scania (Skillinge). For gamma-emitting radionucli
