This paper forms part of a broader study on the design optimization of a high speed switched reluctance motor for automotive traction applications. Due to the high speed operation and resulting high electrical frequency, it is of extreme importance that the different loss components of this motor are accurately calculated. In this study, several effects are observed that influence the accurate mea
We have employed a new approach to quantify the amount fraction of nitrous oxide in a synthetic air matrix gas used to prepare high-accuracy reference materials of the same component. Until now, this was the largest contributor to the measurement uncertainty of nitrous oxide in air reference materials at atmospheric amount fractions (∼330 nmol mol-1), as identified in a recent international compar
Certain oxygenated compounds, called oxygenates, when blended with gasoline, have the ability to inhibit the occurrence of engine knock, thus helping improve spark-ignition engine efficiency. Similarly, oxygenates can also be added to diesel fuel to decrease the exhaust emissions—soot in particular—from diesel engines. Although ethanol and biodiesel have had widespread use as oxygenates for gasoli
Statistics reveal the concerning prevalence of mental health issues among Swedish public sector managers, highlighting the critical need for deeper insights into the relevance of social support in coping with work-related stress. This study aims to examine the relevance of various sources of social support for managers coping with work-related stress, an area relatively underexplored in public adm
A permanently available molecular-beam injection setup for controlled molecules (COMO) was installed and commissioned at the small quantum systems (SQS) instrument at the European x-ray free-electron laser (EuXFEL). A b-type electrostatic deflector allows for pure state-, size-, and isomer-selected samples of polar molecules and clusters. The source provides a rotationally cold (T ≈ 1 K) and dense
In this study, we present the initial results from a long-term initiative to develop a multi-millennial tree-ring width (TRW) chronology for subfossil oak (Quercus spp.) trees in South Scandinavia. We have constructed 40 TRW chronologies, primarily from oak trunks extracted from peatlands, archaeological sites, drainage ditches, and infrastructure projects, as well as some submerged material. The
This study employs computational algorithms to automatically identify and classify features in X-Ray fluorescence (XRF) microscopy images. Principal component analysis (PCA) and unsupervised machine learning algorithms, such as Gaussian mixture (GM) clustering, are implemented to label features on a collection of XRF maps of human atherosclerotic plaque samples. The investigation involves the hard
The interaction between a low angle grain boundary in front of a crack tip and the emerging plasticity from the tip of a microstructurally short edge crack subjected to fatigue loading has been studied. The modeling rests solely on discrete dislocations, were the geometry is described by dislocation dipole elements in a boundary element approach and the plasticity, restricted to one slip plane, to
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of methylxanthines in preventing or treating intermittent hypoxemia or respiratory insufficiency in late preterm infants.
Parkinson's disease is a neurodegenerative condition characterized by motor impairments caused by the selective loss of dopaminergic neurons in the substantia nigra. Levodopa is an effective and well-Tolerated dopamine replacement agent. However, levodopa provides only symptomatic improvements, without affecting the underlying pathology, and is associated with side effects after long-Term use. Cel
We present the design of the vacuum chamber for the LNLS 2T Hybrid Wiggler. The chamber is a 3m long, 1.2mm thick 316L SS tube, which was mechanically pressed into an elliptical shape from an originally round tube. In order to provide the necessary mechanical tolerances, the rather flexible tube is welded to lateral supports that run the complete length of the chamber. Special care has been given
Introduction: The 2024 ISTH clinical practice guideline (CPG) for treatment of congenital haemophilia, the NBDF-McMaster Guideline on Care Models for Haemophilia Management, and ASH ISTH NBDF WFH guidelines on the diagnosis and management of VWD all utilised GRADE methodology. Aim: Discuss missed opportunities and the methodological approach of the ISTH Guideline in contrast to how GRADE was previ
BACKGROUND AND AIM: Warming temperature promotes bacterial growth while extreme precipitation enhances fecal-oral route of exposures to these pathogens, particularly in resource limited settings, increasing burden of diarrheal diseases. Given climate change related increases in frequency of extreme events, there is a pressing need to develop meaningful early warning system with adequate lead time
This presentation presents a method for using Large Language Models (LLMs) to structure historical data about Swedish musical history. The research builds on the existing, human-created Stockholm Concert Database of concerts occurring in Stockholm between 1848-1908. Using this as a starting point, it details an experiment in automated extraction of information about concerts from historical Swedis
PURPOSE OF REVIEW: Small cell lung cancer (SCLC) is an aggressive disease with a poor prognosis, whereas its metastatic capacity carries a predilection for the brain. Although prophylactic cranial irradiation (PCI) has been used to address this problem, upcoming alternatives might necessitate reflection of its application in SCLC treatment. RECENT FINDINGS: The addition of immunotherapy to treatme
Purpose: To remedy the lack of a measure that jointly assesses the psychological status and impact of migration stressors among forced migrants, we developed and tested the Screening of Refugees Self-Report (ScoRE-SR) Questionnaire.Method: Four institutions with expertise on posttraumatic symptomatology and/or migration stressors developed the ScoRE-SR through an iterative process also involving c
This paper explores how pro-active government policies could promote artificial intelligence (AI) in healthcare for the public good. Building on insights from the literature on industrial policy, we argue that without clear conditions and guardrails to ensure future public benefit, state assistance and subsidies will be nothing more than corporate welfare with unpredictable, if any, societal benef
In pursuit of advancing the capabilities of ground testing facilities, a complete road map for broadening operational range of the H3 hypersonic blowdown wind tunnel, operated at the von Karman Institute for Fluid Dynamics (VKI), with the addition of a new Mach 5 contoured nozzle is constructed. The main characteristics of the facility are presented. The supersonic ejector is identified as a criti
