In this paper, a novel generalized transition matrix (GTM) algorithm is proposed to analyze the electromagnetic problems of open-ended cavity structures. An artificial reference surface is applied to seal the slots and/or apertures to reshape the target cavity into an interior domain (containing inner metallic surface and internal structures) and an exterior domain (containing the outer surface of
Construction of synthetic basis functions (SBFs) for analyzing the radiation problems of antenna arrays is discussed. The SBFs of a block are generated from two separate solution spaces, with one space to account for the effect of the feeding voltages, and the other space to account for the responses of the block to incident electromagnetic fields from its environment. Singular value decomposition
This paper introduces a modified construction method of synthetic basis functions (SBFs) for analyzing the radiation problems of phased antenna arrays. The effect of the feeding sources and the responses of incident electromagnetic fields are two relatively independent solution spaces. Singular value decomposition (SVD) method is used to extract the characteristic modes to the array from the two s
Background: Patients with hallux valgus deformity may require surgery but prospective patient-reported data is scarce. Methods: We evaluated 53 patients with a mean age of 55.3 years (SD 14.1, 50 women), who underwent surgery due to hallux valgus. They completed the PROMs SEFAS, EQ-5D and SF-36 before and 6, 12 and 24 months after surgery. Results: All patient-reported outcomes improved at 6, 12 a
Background: Transarterial embolization with particles is a relatively common treatment method in both malignant and benign disorders. Permanent occlusion of the uterine arteries may sometimes be disadvantageous. Purpose: To compare the local tissue effects, possible side effects, and extent of recanalization following uterine artery embolization, using either degradable or non-degradable microsphe
Background/Aim: Prostate cancer (PCa) diagnosis using patient urine samples represents a non-invasive and more convenient method than the conventional biopsy and prostate-specific antigen (PSA) test. This study intended to identify a biomarker panel to distinguish PCa from benign prostate using urine samples. Materials and Methods: We identified six biomarkers with differential gene expression in
Purpose: Patients undergoing surgery for thumb carpometacarpal (CMC1) osteoarthritis often require sick leave owing to postoperative immobilization, pain, and decreased function. Our goal was to evaluate the amount of sick leave after surgery for 2 common CMC1 arthroplasty procedures. Methods: Using registry data from the Skåne region of southern Sweden, cross-linked with employment data showing p
Bluff-body flame holders are commonly employed in many industrial applications. A bluff-body is usually adopted to enhance the downstream mixing of the combustion products and the fresh fuel-air mixtures, thus to improve the flame stability and to control the combustion process. In the present paper, flames stabilized by a conical-shape bluff-body flame holder with a central air/fuel jet were stud
Objective: Continuity with a known midwife might benefit women with fear of birth, but is rare in Sweden. The aim was to test a modified caseload midwifery model of care to provide continuity of caregiver to women with fear of birth. Methods: A feasibility study where women received antenatal and intrapartum care from a known midwife who focused on women's fear during all antenatal visits. The stu
There is an enormous genetic diversity evident in modern yeasts, but our understanding of the ecological basis of such diversifications in nature remains at best fragmented so far. Here we report a long-term experiment mimicking a primordial competitive environment, in which yeast and bacteria co-exist and compete against each other. Eighteen yeasts covering a wide phylogenetic background spanning
Introduction: Lung cancer, a common malignancy and cause of cancer-related deaths, is strongly linked to several environmental exposures, and thus primarily affects the elderly. Formerly a man's disease, its incidence is rising among women, and lung cancer is now more common in women than men in Sweden. Women are particularly over-represented among young patients. While overall cancer mortality in
This paper offers a formally driven quantitative analysis of stance-annotated sentences in the Brexit Blog Corpus (BBC). Our goal is to identify features that determine the formal profiles of six stance categories (CONTRARIETY, HYPOTHETICALITY, NECESSITY, PREDICTION, SOURCE OF KNOWLEDGE and UNCERTAINTY) in a subset of the BBC. The study has two parts: firstly, it examines a large number of formal
The purpose of this paper is to describe strategic improvisation, a contemporary concept and approach based on the creative arts and organizational crisis theory, as a valuable approach for communication professionals. Strategic improvisation combines the need for planning and structure with creative action, and is a normative idea of how to work in an efficient way.Design/methodology/approach: Th
In order to meet the requirements in the stringent emission regulations, more and more research work has been focused on homogeneous charge compression ignition (HCCI) and partially premixed combustion (PPC) or partially premixed compression ignition (PCCI) as they have the potential to produce low NOx and soot emissions without adverse effects on engine efficiency. The mixture formation and charg
Background: Pain from various locations in the body and mental illness are common and the comorbidity between the two is well-known although the temporal relationship remains to be determined. Our aim was to follow patients over time to study if pain (here dorsalgia/abdominal pain) or fibromyalgia lead to an increased risk of developing mental illness (here depression/anxiety) and/or the reverse,
Impaired incretin effect is a culprit in Type 2 Diabetes. Cocaine- and amphetamine-regulated transcript (CART) is a regulatory peptide controlling pancreatic islet hormone secretion and beta-cell survival. Here we studied the potential expression of CART in enteroendocrine cells and examined the role of CART as a regulator of incretin secretion and expression. CART expression was found in glucose-
Background and Aims: To investigate the paraclinical and pathological features of surgically resected intraductal papillary mucinous neoplasms in Sweden. Materials and Methods: A review of prospectively collected data on patients undergoing pancreatic resection for a histopathologically verified intraductal papillary mucinous neoplasm between 2010 and 2016 was performed using the Swedish National
Purpose – The purpose of this paper is to demonstrate that, important as reflexivity is, it does not constitute the gold standard of qualitative research. Instead the author makes a plea for the use of sociological imagination. Design/methodology/approach – The paper makes use of data from the ISI Web of Science database to demonstrate the increasing popularity of the concept of reflexivity. Findi
Background: The annual mortality for patients on dialysis is high even if it has decreased from 30 % in 1991 to 18 % in 2016. It is mainly caused by an increased cardiovascular and infectious morbidity. Previous studies have reported improved survival for patients with home hemodialysis (HHD). However, patients starting HHD are younger and healthier compared to patients starting other dialysis mod
