The purpose of this work was to develop a contrast-detail phantom that can be used to evaluate image quality in breast tomosynthesis (BT) and as a first step use it to evaluate in-plane artifacts with respect to object size and contrast. The phantom was constructed using a Polylite [registered trademark] resin as bulk material, as it has x-ray mass attenuation properties similar to polymethyl meth
Social Network Games (SNGs) first appeared in Asia in the latter half of the 00s, and soon became a widespread phenomenon all over the world. In the West, US developer Zynga quickly rose to fame with their hit title FarmVille, and now enjoys a nearly monopolistic position among games on Facebook. In Japan as well, the SNG industry has grown at an exceptional pace since its birth and is predicted t
Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. These two pollutants are emitted due to a combination of high local cAlternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions.

Objective: Steady state insulin-like growth factor-1 (IGF-1) levels vary significantly during continuous intravenous infusion of recombinant human insulin-like growth factor-1/recombinant human insulin-like growth factor binding protein-3 (rhIGF-1/rhIGFBP-3) in the first weeks of life in extremely preterm infants. We evaluated interleukin-6 (IL-6) and insulin-like growth factor binding protein-1 (
Lakes are a key feature of arctic landscapes and can be an important component of regional organic carbon (OC) budgets, but C burial rates are not well estimated. 210 Pb-dated sediment cores and carbon and organic matter (as loss-on-ignition) content were used to estimate OC burial for 16 lakes in SW Greenland. Burial rates were corrected for sediment focusing using the 210 Pb flux method. The
Background: Video capsule endoscopy (VCE) is a noninvasive method enabling excellent visualization of the small bowel (SB) mucosa. The aim of this study was to examine the impact and safety of VCE performed in children and adolescents with suspected or established Crohn’s disease (CD). Methods: A total of 180 VCE examinations in 169 consecutive patients conducted in 2003–14 in a single center were
The electrochemical and electrical properties of geometrically defined electrolyte-filled microelectrodes were studied at various transelectrode current passages, using radiotracer (38Cl and 42K) and electrical techniques. Geometrically, the electrodes were defined by their tip properties that, for standard (single-barrelled, 3.0 M KCl-filled, approximately 10 M[ohm]) electrodes implied a tip open
User participation in requirement analysis (RA) is necessary for IS quality and user acceptance. A prerequisite for meaningful user participation is that the coming users also understand the requirements. This understanding is made difficult by abstract and “technical” modelling languages and notations which require learning and experience. The Business Rules Approach (BRA) builds on a notion of B
The chaperone DNAJB6b (JB6) plays important roles in increasing amyloid protein solubility and inhibiting amyloid fibril formation, a causative factor for neurodegenerative diseases like Alzheimer's and Parkinson's disease. Insights into the biophysical properties of JB6, including its structure, self-assembly and stability towards denaturation, may enhance the understanding of the physicochemical
Importance: Quality of life is not a standard primary outcome in ablation trials, even though symptoms drive the indication.Objective: To assess quality of life with catheter ablation vs antiarrhythmic medication at 12 months in patients with atrial fibrillation.Design, Setting, and Participants: Randomized clinical trial at 4 university hospitals in Sweden and 1 in Finland of 155 patients aged 30
An overabundance of evidence, both observational and from model projections, indicate that changes to the climate system are taking place at unprecedented rates. Although the magnitudes of these changes involve large uncertainties, the fact that our climate is changing is unequivocal. To ensure an unimpaired functionality of our societies,it is therefore of crucial importance to study the potentia
Objectives: The aim of this feasibility study was to evaluate the added value of contrast-enhanced mammography (CEM) in preoperative staging of malignant breast lesions, beyond standard assessment with digital mammography and ultrasound, as a base for a future prospective randomized trial. Materials and methods: Forty-seven patients, with confirmed or strongly suspected malignant breast lesions af
To clarify whether metabolic control and β‐cell function deteriorate with increasing duration of diabetes, we investigated in a cross‐sectional study Type 2 diabetic patients in an area‐based population. Type 2 diabetic patients (n = 231: 112 males, 119 females) were identified by age at onset > 35 years, fasting levels of C‐peptide > 0.04 nmol l−1, and absence of islet cell antibodies. Body weigh
Introduction: Breathlessness is common in the population, especially in women and associated with adverse health outcomes. Obesity (body mass index (BMI) >30 kg/m2) is rapidly increasing globally and its impact on breathlessness is unclear. Methods: This population-based study aimed primarily to evaluate the association of current BMI and self-reported change in BMI since age 20 with breathlessnes
BACKGROUND AND AIMS: One out of three men who undergo cystoprostatectomy for bladder cancer is diagnosed with incidental prostate cancer (PCa) at histopathological examination. Many of these men are PSA tested as part of their follow-up, but it is unclear if this is needed. The aim of this study was to assess the risk of PCa death in these men and the need of PSA-testing during follow-up. METHODS:
The emergence of short video (e.g. TikTok) provides a new avenue for destination marketing. However, limited research exists on short ice-snow destination videos, which are significant for Nordic winter tourism marketing. Drawing on a model based on parasocial interaction theory, this study finds that ice-snow celebrity attachment positively predicts Chinese tourists’ parasocial interaction, enjoy
There are hundreds of thousands of moth species with crucial ecological roles that are often obscured by their nocturnal lifestyles. The pigmentation and appearance of moths are dominated by cryptic diffuse shades of brown. In this study, 82 specimens representing 26 moth species were analysed using infrared polarimetric hyperspectral imaging in the range of 0.95–2.5 µm. Contrary to previous studi
