In this paper, we extend the notion of affine shape, introduced by Sparr, from finite point sets to curves. The extension makes it possible to reconstruct 3D-curves up to projective transformations, from a number of their 2D-projections. We also extend the bundle adjustment technique from point features to curves. The first step of the curve reconstruction algorithm is based on affine shape, is in
Obstetric records of hospital births of children present in the Scanian Economic Demographic Database. The records contain information on gestational age, birthweight, and other indicators of health of the child, as well as information on maternal health.
Estimation of the defect content is important to enable quality control throughout the software development process. Capture-recapture methods and curve fitting methods have been suggested as tools to estimate the defect content after a review: The methods are highly reliant on the quality of the data. If the number of reviewers is fairly small, it becomes difficult or even impossible to get relia
Corvids are known for their cognitive flexibility, and many have innovated various forms of tool use. Here, we review tool use and tooling in common ravens (Corvus corax) and describe additional observations. In total, they have used tools in 10 submodes and 11 modes. Of these modes, four were observed in captivity only, four in the wild only and three in both contexts. Five of these modes constit
BackgroundPostural orthostatic tachycardia syndrome (POTS) is a common cardiovascular autonomic disorder characterized by excessive heart rate increase on standing and symptoms of orthostatic intolerance, posing significant limitations on functional capacity. No objective tool exists to classify symptom burden in POTS.MethodsWe conducted a case-control study in 62 POTS patients and 50 healthy cont
The medical imaging technique called “ultrasound optical tomography” (UOT) entails light scattered in tissue that is given spatial information by interacting with an ultrasound field, thus allowing for molecular information to be imaged with ultrasonic resolution. This thesis discusses how UOT can be implemented, with most attention put toward the implementation using spectral-hole-burning filters
The CORDEX Flagship Pilot Study ELVIC (climate Extremes in the Lake VICtoria basin) was recently established to investigate how extreme weather events will evolve in this region of the world and to provide improved information for the climate impact community. Here we assess the added value of the convection-permitting scale simulations on the representation of moist convective systems over and ar
Background: Previous studies have reported Blood type O to confer a lower risk of SARS-CoV-2 infection, while secretor status and other blood groups have been suspected to have a similar effect as well. Study design and methods: To determine whether any other blood groups influence testing positive for SARS-CoV-2, COVID-19 severity, or prolonged COVID-19, we used a large cohort of 650,156 Danish b
Ecosystem-based protection is becoming a viable adaptation option to conventional engineered solutions to rising sea levels and coastal erosion. While the environmental and biological ecosystem services provided by ecosystem-based adaptation measures such as beach nourishment and/or seagrass plantations are being acknowledged and analysed, less attention has been paid to the social or cultural dim
Spatial analysis of peace and conflict is slowly but steadily gaining traction. As a new and innovative approach, it focuses on the mutual construction of spaces and agency in a field that has thus far merely considered space as a backdrop against which war, violence, and peace unfold. Conceptually borrowing from disciplines such as geography, anthropology, and others, in this article we propose t
This is a cartographic vertical analysis of a verdict by the Swedish Supreme Administrative Court, regarding the right to support from the Social Services (HFD 2017 ref. 33). The case concerned three children and their motherwhom lacked formal residency. They applied for assistance under the Social Services Act and the municipality’s health and welfare committee rejected the application. Following
This paper introduces the Lang-Track-App, a smartphone application and backend system to aid second language acquisition researchers in implementing the experience sampling method (ESM). Surveying research participants with the Lang-Track-App multiple times per day can yield exceptionally rich data that can be analyzed in multiple ways. This article explains the different Lang-Track-App components
This paper discusses the limits of intergovernmental flexibility in the area of freedom, security and justice with a main focus on the case of SN and SD. The judgment represents the first legal challenge to the new surrender mechanism between the EU and the UK post-Brexit. Reflecting on general criteria of legal basis litigation, the crux of the matter concerns the Irish opt-out under Protocol No
Denna artikel behandlar några av de förändringar som genomfördes i svensk migrationslagstiftning under 2016 för att minska antalet asylsökande, öka incitamenten för självmant återvändande och tydligt signalera till omvärlden att andra länder i Europa måste träda fram och dela ansvaret för flyktingmottagandet. Syftet med artikeln är att reflektera över hur de dramatiska kursändringar som ägde rum g
Tick-borne encephalitis (TBE) is an emerging infection causing CNS infection of various severity. Good knowledge of the incidence in the population and defined risk areas is important in risk communication and vaccination recommendations. The aim of this study was to investigate potential underreporting by retrospectively diagnose TBE among patients with viral CNS infections of unknown etiology in
Humanitarian considerations in the Swedish asylum process. A study of the migration authorities’ balancing act between solidarity and inequality. Medical certi cates are becoming increasingly important as a basis for asylum assessments. Using examples from 24 asylum decisions concerning children and their families, the present article discusses how the Swedish Migration Agency and the Migration Co
Background: Survivors of childhood cancer are at risk of subsequent primary malignant neoplasms (SPNs), but the risk for rarer types of SPNs, such as oral cancer, is uncertain. Previous studies included few oral SPNs, hence large-scale cohorts are required to identify groups at risks. Methods: The PanCareSurFup cohort includes 69,460 5-year survivors of childhood cancer across Europe. Risks of ora
Purpose: Hematoma volume is the strongest predictor of patient outcome after intracerebral hemorrhage (ICH). The aim of this study was to validate novel fully automated software for quantification of ICH volume on non-contrast computed tomography (CT). Methods: The population was defined from the Swedish Stroke Register (RS) and included all patients with an ICH diagnosis during 2016–2019 in Regio
