Inclusive and differential cross-sections for the production of top quarks in association with a photon are measured with proton-proton collision data corresponding to an integrated luminosity of 139 fb−1. The data were collected by the ATLAS detector at the LHC during Run 2 between 2015 and 2018 at a centre-of-mass energy of 13 TeV. The measurements are performed in a fiducial volume defined at p
INTRODUCTION: Type 1 diabetes (T1D) is caused by the destruction of pancreatic islet beta cells resulting in total loss of insulin production. Recent studies have suggested that the destruction may be interrelated to plasma lipids.OBJECTIVES: Specific lipids have previously been shown to be decreased in children who develop T1D before four years of age. Disturbances of plasma lipids prior to clini
The EC Directive 2013/59/Euratom states in article 56 that exposures of target volumes in nuclear medicine treatments shall be individually planned and their delivery appropriately verified. The Directive also mentions that medical physics experts should always be appropriately involved in those treatments. Although it is obvious that, in nuclear medicine practice, every nuclear medicine physician
Purpose of Study: To gain Swedish norm value for the Life Satisfaction Index-A (LSI-A) in a population 60–93+ years old stratified for sex and age and to relate these norm values with respect to number of chronic diseases and functional impairment. Materials and Methods: The study population included a random sample of 2656 men (45.7%) and 3159 (54.3%) women from the longitudinal national studies’
Background: Both bullying victimization and perpetration were associated with depression, social phobia, physical and psychological child abuse and Internet addiction in Lebanon. The prevalence of bullying in Lebanon is alarming, with 50% of school-aged children and adolescents reporting being bullied at some point. The high rate of both bullying victimization can be reflective of the inefficacy o
It is known from experimental findings that three-dimensional effects can have a strong influence on magnetic shape memory behavior. Such phenomena are, however, often neglected in MSMA constitutive models, as they only become meaningful under complex loading conditions. The extensions of our original modeling framework, cf. Bartel et al. (2020), to include 3D-effects is threefold: (i) vector-valu
Purpose of ReviewIt is important to examine what effect sleep has after an emotional experience. More knowledge about this topic could help inform us whether there are any potential sleep interventions that could help make sure that memories of negative emotional experiences are processed in the most adaptive manner possible.Recent FindingsFindings on the role of sleep in altering reactivity to em
Microbunching instability (MBI) has been one of the most challenging issues in designs of high-brightness beam transport lines for single-pass or recirculating accelerators. Although the intrabeam scattering (IBS) has long been studied in lepton or hadron storage rings as a slow diffusion process or in high-intensity proton linear accelerators as one mechanism for the beam halo, the effects of IBS
BACKGROUND: Central venous catheter (CVC) misplacement occurs frequently after right subclavian vein catheterization. It can be avoided by using ultrasound to confirm correct guidewire tip position in the lower superior vena cava prior to CVC insertion. However, retraction of the guidewire during the CVC insertion may dislocate the guidewire tip from its desired and confirmed position, thereby res
The ability of calcium to suppress the secretion of parathyroid hormone (PTH) is impaired in primary hyperparathyroidism (pHPT). Whether the nonadenomatous glands in pHPT also exhibit altered calcium/PTH homeostasis is not known, but this may be the case since in the immediate postoperative period after surgery for pHPT, hypocalcemia often evolves in spite of a rapid normalization of serum levels
Objectives: We have observed clinical cases where bone is formed in the overlaying muscle covering surgically created bone defects treated with a hydroxyapatite/calcium sulphate biomaterial. Our objective was to investigate the osteoinductive potential of the biomaterial and to determine if growth factors secreted from local bone cells induce osteoblastic differentiation of muscle cells. Materials
Clasts in the CM2 carbonaceous chondrite Lonewolf Nunataks (LON) 94101 have been characterized using scanning and transmission electron microscopy and electron microprobe analysis to determine their degrees of aqueous alteration, and the timing of alteration relative to incorporation of clasts into the host. The provenance of the clasts, and the mechanism by which they were incorporated and mixed
A selection of searches by the ATLAS experiment at the LHC for the electroweak production of SUSY particles are used to study their impact on the constraints on dark matter candidates. The searches use 20 fb−1 of proton-proton collision data at s=8 TeV. A likelihood-driven scan of a five-dimensional effective model focusing on the gaugino-higgsino and Higgs sector of the phenomenological minimal s
When introduced in 1992, the Lund concept (LC) was the first complete guideline for treatment of severe traumatic brain injury (s-TBI). It was a theoretical approach, based mainly on general physiological principles-i.e., of brain volume control and optimization of brain perfusion and oxygenation of the penumbra zone. The concept gave relatively strict outlines for cerebral perfusion pressure, flu
PURPOSE: To present Swedish Macula Register (SMR) data regarding treatment of neovascular age-related macular degeneration (AMD) in clinical practice since 2008.METHODS: A retrospective register-based study was conducted. Evaluation of baseline demographics, visual outcome and number of injections during this period is presented.RESULTS: Mean age at diagnosis was 79 ± (SD) 8 years; 65% were female
Background: To date, the estimated radiation-absorbed dose to organs and tissues in patients undergoing diagnostic examinations in nuclear medicine is derived via calculations based on models of the human body and the biokinetic behaviour of the radiopharmaceutical. An internal dosimetry computer program, IDAC-Dose2.1, was developed based on the International Commission on Radiological Protection
This article aims to contextualise the development of the Code of Ethics for Professional Accountants by the International Federation of Accountants (IFAC) between 1977 and 2006. Drawing on transnational regulation literature, an extensive review of archival documents was conducted. The analysis unfolds the development of the Code in an increasingly complex regulatory environment, revealing the dy
In the last decade, museums that were established in the 20th century by immigrants from the five Nordic countries have become increasingly concerned with broadening their audiences and more actively engaging their visitors. Efforts to do this have varied from offering traveling exhibitions produced in the Nordic countries, film programs, festivals, concert series, cocktail hours, culinary confere
