The polar format algorithm (PFA) is a popular choice for general bistatic synthetic aperture radar (BiSAR) imaging due to its computational efficiency and adaptability to situations with complicated geometries or arbitrary flight trajectories. However, efficient and accurate compensation of 2-D residual phase errors induced by the wavefront curvature remains challenging when obtaining high-quality

A Brain-Computer Interface (BCI) is a system that, in real-time, translates the user's brain activity into commands that can be used to control applications, such as moving a cursor on the screen. The translation is made possible by machine learning methods and other algorithms. The thesis focuses on EEG-based BCIs which are the most common type of BCIs due to EEG measurements being non-invasive,

Platinum-tin surfaces are active for CO oxidation, but their activity and the effects of tin oxide phases that form under reaction conditions are poorly understood. We have studied surface alloys of tin prepared on platinum single crystals during catalytic CO oxidation using near-ambient-pressure X-ray photoemission spectroscopy. On the flat terraces of Sn/Pt(111), a wetting layer of Sn(II) surfac

Background and purpose: Advances in characterizing cancer biology and the growing availability of novel targeted agents and immune therapeutics have significantly changed the prognosis of many patients with metastatic disease. Palliative radiotherapy needs to adapt to these developments. In this study, we summarize the available evidence for stereotactic body radiotherapy (SBRT) in the treatment o

The dominant road traffic particle sources are wear particles from the road and tire interface, and from vehicle brake pads. The aim of this work was to investigate the effect of road and brake wear particles on pulmonary function and biomarkers in isolated perfused rat lungs. Particles were sampled from the studded tire wear of three road pavements containing different rock materials in a road si

This article investigates the transformation of the body of a female child murderer as she passed through specific spatial configurations in the urban setting of the seventeenth-century capital of Denmark-Norway. By using the case of Gertrud Nielsdatter, we explore the significance of public urban spaces in the bodily and material transformation of a woman from a condemned sinner to an object of s

Background: Survivors of childhood cancer may face difficulties at school. We investigated whether childhood cancer affects attainment of upper secondary education, in a register-based cohort study from Denmark, Finland, and Sweden, where we limit bias from selection and participation. Methods: From the national cancer registers, we identified all long-term survivors of childhood cancer diagnosed

Following the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) treatment algorithm for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), patients suffering from severe uncontrolled CRSwNP are recommended to receive oral corticosteroids, (revision) sinus surgery, systemic biologicals and/or aspirin treatment after desensitization (ATAD). Given the major diff

Using Swedish registers, we examine whether the prescription of and the response to antidepressants (AD), mood stabilizers (MS), and antipsychotics (AP) in the treatment of, respectively, major depression (MD), bipolar disorder (BD), and schizophrenia (SZ), are influenced by familial-genetic risk. We examined individuals born in Sweden 1960–1995 with a first diagnosis of MD (n = 257,177), BD (n =

The experience of heritage sites through digital technology is an increasingly important topic for researchers and practitioners. Drawing upon telepresence theory, this study explores how a visitor’s destination image is formed and its impact on satisfaction in a virtual heritage site experience. The survey results show that telepresence, cognitive image, affective image, and satisfaction are posi

PURPOSE: To investigate estimated delivered dose distributions using weekly cone-beam computed tomography (CBCT) scans for pelvic organs at risk (OARs) in salvage radiotherapy (SRT) after radical prostatectomy. Furthermore, to compare them with the originally planned dose distributions and analyse associations with gastrointestinal (GI) and genitourinary (GU) side effects.METHODS: This study is pa

Background Prior research has reported an association between divorce and suicide attempt. We aimed to clarify this complex relationship, considering sex differences, temporal factors, and underlying etiologic pathways. Methods We used Swedish longitudinal national registry data for a cohort born 1960-1990 that was registered as married between 1978 and 2018 (N = 1 601 075). We used Cox proportion

Vårt land har inte blivit rikt och fritt genom monopol och korporativism. Striden mellan LO och Tesla pekar på en central fråga: ska det svenska samhället vila på individorienterad grund eller starka särintressen?

The pair-distribution function, which provides information about correlations in a system of interacting particles, is one of the key objects of theoretical soft matter physics. In particular, it allows for microscopic insights into the phase behavior of active particles. While this function is by now well studied for two-dimensional active matter systems, the more complex and more realistic case

Introduction: Although ischemic stroke incidence has decreased in Sweden over the past decade, trends in spontaneous intracerebral hemorrhage (ICH) incidence are less well delineated. In this time period, there has been a dramatic increase in use of oral anticoagulants (OAC). The aim of our study was to investigate incidence trends in spontaneous first-ever ICH in Sweden between 2010 and 2019, wit

Objectives: The objective of this study was twofold: to determine the prevalence of arterial and venous thromboembolic events in the Norwegian Hereditary Hemorrhagic Telangiectasia (HHT) population, and to explore potential factors linked to such events, with particular emphasis on FVIII. Methods: Patients with an HHT diagnosis attending the Otorhinolaryngology Department at Oslo University Hospit

The fascination with the “Eastern Wisdom” exhibited among esoteric movements in the late nineteenth and early twentieth century is often understood as an interest in spirituality. Existing research has focused on how these movements took an interest in beliefs in doctrines like karma and reincarnation, as well as in practices of meditation and divination. Although this characterization is broadly
