Introduction Using body mass index (BMI) as a proxy, previous Mendelian randomization (MR) studies found total causal effects of general obesity on polycystic ovarian syndrome (PCOS). Hitherto, total and direct causal effects of general- and central obesity on PCOS have not been comprehensively analyzed. Objectives To investigate the causality of central- and general obesity on PCOS using surrogat
Choices of regularization parameters are central to variational methods for image restoration. In this paper, a spatially adaptive (or distributed) regularization scheme is developed based on localized residuals, which properly balances the regularization weight between regions containing image details and homogeneous regions. Surrogate iterative methods are employed to handle given subsampled dat
This thesis compares how Sweden and Finland’s contrasting exchange rate regimes shaped their export sector performance during the 2008 Global Financial Crisis. While both are small, open Nordic economies, Sweden maintained a floating currency and independent monetary policy, whereas Finland adopted the euro and ceded monetary control to the European Central Bank. The study evaluates export revenue
The movement and distribution of ecologically important herbivores such as elephants are of great significance to conservation biologist seeking to understand the fundamental triggers that influence their mobility and the extent to which these parameters affect how they utilize their immediate and surrounding resources. The recent advancement in animal tracking technology coupled with the availabi
Popular Abstract in Swedish Många av dagens stora folksjukdomar, såsom cancer, diabetes och hjärt-kärlsjukdomar, kopplas i allt högre grad samman med olika riskfaktorer som beror på förändringar i arvsmassan. Dessa nya kopplingar har möjliggjorts tack vare den extrema utveckling av genetiska mätmetoder som har skett under de senaste 15 åren. Med de nya metoderna kan förekomsten och aktiviteten hosThis thesis deals with methods for extracting robust and relevant information from high-dimensional data sets, and statistically guided visualization methods for representing the data in an informative and easily accessible way. High-dimensional data sets are becoming increasingly prevalent in many different scientific disciplines. In this thesis, we focus particularly on so called "omics" data. T
The present study describes the development and testing of a tool for dolphin research. This tool was able to visualize the dolphin echolocation signals as well as function as an acoustically operated “touch screen”. The system consisted of a matrix of hydrophones attached to a semi-transparent screen, which was lowered in front of an underwater acrylic panel in a dolphin pool. When a dolphin aime
How was the atomic age visualized in Egypt in the years immediately after the creation of the bomb? What role did gendered images, symbols and metaphors play in narrating and normalizing nuclear technology? How can these help us understand nuclear policy today? This article engages visual and textual media, including satirical magazines, cultural journals and film. It presents a plurality of image

Geological time is by many geoscience instructors considered a threshold concept for geoscience students, being a central concept for how we experience geosceince phenomena that takes place on a spatio-temporal scale ranging from micro (e.g. cloud formation) to macro (e.g. plate tectonics).

This article is a Bioarchaeology of Care and Disability focused analysis of an individual who suffered a severe fracture of the left knee in Late Medieval Lund, Scania (1300–1536 CE). We question the degree to which written sources from the period represent the reality of the disability experience, and to that end how identities intersect in the Medieval urban landscape. Following an index of care
Background: Three-dimensional time-resolved (4D) phase-contrast (PC) CMR can visualize and quantify cardiovascular flow but is hampered by long acquisition times. Acceleration with SENSE or k-t BLAST are two possibilities but results on validation are lacking, especially at 3 T. The aim of this study was therefore to validate quantitative in vivo cardiac 4D-acquisitions accelerated with parallel i
Many important scientific questions in physics, chemistry and biology require effective methodologies to spectroscopically probe ultrafast intra- and inter-atomic/molecular dynamics. However, current methods that extend into the femtosecond regime are capable of only point measurements or single-snapshot visualizations and thus lack the capability to perform ultrafast spectroscopic videography of

A high spatiotemporal resolution technique for instantaneous flow field measurement has been developed, enabling one-dimensional velocimetry and flow field visualization within a converging–diverging nozzle. By employing femtosecond laser-induced long-lived, high-intensity plasma emission in a CO2/N2 gas flow, coupled with an ICCD camera, we achieved instantaneous one-dimensional velocity measurem
