Introduction: Medical treatment of women with idiopathic recurrent pregnancy loss is controversial. The objective was to assess the effects of different treatments on live birth rates and complications in women with unexplained recurrent pregnancy loss. Material and methods: We searched MEDLINE, Embase and the Cochrane Library, and identified 1415 publications. This systematic review included 21 r

Artikeln vill ge bakgrundshistoria och orientering om dagens situation för mi’kmaq, en etnisk folkgrupp, som främst bebor reservat på Kanadas ostkust. Historiken uppvisar en koloniserad grupp, som influerats av britternas annektering av provinsen och den franska, katolska missionen, men samtidigt finns idag en ny stolthet över att vara mi’kmaq, med reservatslivets mödor och glädjeämnen som gruppen

Det behövs en bredare förståelse för AI-teknologins sociala, etiska och rättsliga effekter, skriver sex företrädare för universitetsvärlden och näringslivet. Sverige har goda möjligheter att nå framgång i den kapplöpning som pågår när det gäller artificiell intelligens, AI. Men det kräver att politiker, universitetsvärlden och näringslivet samverkar och bygger upp en tvärvetenskaplig kompetens.

A critical factor for electronics based on inorganic layered crystals stems from the electrical contact mode between the semiconducting crystals and the metal counterparts in the electric circuit. Here, a materials tailoring strategy via nanocomposite decoration is carried out to reach metallic contact between MoS2 matrix and transition metal nanoparticles. Nickel nanoparticles (NiNPs) are success

Ljus kan användas till många saker, allt från att sända radiosignaler och skicka information i optiska fibrer, till att lysa upp hem och utvinna energi via solceller. Det ljus vi är mest vana vid som människor är ett intervall av våglängder mellan 400 och 700 nanometer (en nanometer är en miljarddels meter), som svarar mot alla synliga färger mellan rött och violett. Ett sätt att undersöka sammansIn this thesis we discuss a theoretical description of ultrafast and non-linear spectroscopy. Due to the high intensities and ultrashort pulse durations involved in such experiments, it is necessary to use an explicitly time-dependent formalism. In addition, many of the systems we have considered exhibit strong interactions between the constituent particles, such as electron-electron, electron-nuc

Light-use efficiency (LUE), which quantifies the plants' efficiency in utilizing solar radiation for photosynthetic carbon fixation, is an important factor for gross primary production estimation. Here we use satellite-based solar-induced chlorophyll fluorescence as a proxy for photosynthetically active radiation absorbed by chlorophyll (APARchl) and derive an estimation of the fraction of APARchl

Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. These estimation problems are called minimal problems, and they can often be formulated as systems

The utilization of lignocellulosic biomass to produce biofuels, such as bioethanol, has the potential to provide a sustainable alternative to fossil fuels, and thus mitigate greenhouse gas emissions from the transportation sector.Forest biomass is expected to be a significant source of such biomass, as it can serve as an abundant and sustainable feedstock for bioethanol production. It is unlikely

Background: A hip fracture is a common cause of morbidity, functional disability, and decreased health-related quality of life (HRQOL). With demographic changes showing a growing proportion of older people, hip fractures will be an increasing challenge for healthcare services in the future. Hip fractures threaten the independence of individuals in their everyday lives. In Sweden, more than one thiBackground: A hip fracture is a common cause of morbidity, functional disability, and decreased health-related quality of life (HRQOL).

This thesis proposes a unique quantitative investigation of the long-term development of modern states in Sub-Saharan Africa. This is done by measuring and analysing the dynamic history of tax revenue, as a key measure of the capacity of the state, and development in four countries in francophone West Africa – Benin, Côte d’Ivoire, Niger and Senegal – over the long 20th century. This approach cont

BACKGROUND: Identification of risk factors for rapid joint destruction in early rheumatoid arthritis (RA) can be helpful for optimizing treatment, and improving our understanding of destructive arthritis and its mechanisms. The objective of this study was to investigate the relationship between early RA patient characteristics and subsequent rapid radiographic progression (RRP).METHODS: An incepti

Introduction: Apolipoprotein E (APOE) ε4 is the major genetic risk factor for Alzheimer's disease (AD), but its prevalence is unclear because earlier studies did not require biomarker evidence of amyloid β (Aβ) pathology. Methods: We included 3451 Aβ+ subjects (853 AD-type dementia, 1810 mild cognitive impairment, and 788 cognitively normal). Generalized estimating equation models were used to ass

One of the greatest impediments to the use of probabilistic reasoning in legal arguments is the difficulty in agreeing on an appropriate prior probability for the ultimate hypothesis, (in criminal cases this is normally “Defendant is guilty of the crime for which he/she is accused”). Even strong supporters of a Bayesian approach prefer to ignore priors and focus instead on considering only the lik

This article addresses the question whether maternal mortality should be excluded from the study of excess female mortality. This phenomenon points to lower survival chances for women in certain age groups as opposed to men in the same age group. The existence of excess female mortality has been established for a number of European countries, primarily for the nineteenth century period, and it has
