Background: In stage I/II natural killer (NK)/T-cell lymphoma, concurrent chemoradiotherapy (CCRT) had previously been shown to result in superior outcome compared with anthracycline-containing regimens, which have since been considered ineffective. The role of CCRT in comparison with approaches employing nonanthracycline-containing chemotherapy (CT) and sequential radiotherapy (RT) in such patien
Background Quinquennial overviews (1985-2000) of the randomised trials in early breast cancer have assessed the 5-year and 10-year effects of various systemic adjuvant therapies on breast cancer recurrence and survival. Here, we report the 10-year and 15-year effects. Methods Collaborative meta-analyses were undertaken of 194 unconfounded randomised trials of adjuvant chemotherapy or hormonal ther
The most used pavement for paved roads in the world is asphalt. It is therefore important that the asphalt is as durable as possible to avoid expensive repairs of the roads. One important factor of the durability of the road is the adherence between the stones and the bitumen that holds the stones together. The affinity is tested by the so called rolling bottle test, where one put stones covered i
A well-planned waiting area is crucial for automatic milking systems. In an enclosed waiting area, cows of different rank compete for entering the milking station and they are exposed for a variety of social interactions. Such interactions could increase standing time and delay milking, which may result in stress, lameness, impaired welfare and reduced performance. The aim was to monitor the waiti
In this paper we present a system for performing low rank matrix factorization. Low-rank matrix factorization is an essential problem in many areas including computer vision, with applications in e.g. affine structure-from-motion, photometric stereo, and non-rigid structure from motion. We specifically target structured data patterns, with outliers and large amounts of missing data. Using recently
En stor andel av vuxna svenskar planerar under sitt yrkesamma liv för sin ekonomi när de slutar arbeta genom att pensionsspara. Även lagstiftaren anser det vara viktigt att det planeras för framtiden och lämnar skattekredit till dem som väljer att pensionsspara genom pensionsförsäkring eller individuellt pensionssparande. Då man pensionssparar just för att få en bättre ekonomisk situation på ålderA large proportion of Swedish adults plan for their economy while working by saving for the retirement. The legislator also establishes the importance of planning for the future by granting a tax credit for those who choose to save for the retirement in certain products defined by law. The legal protection of capital savings when saving for a better financial situation when you reach retirement is
I flera sociologiska teorier möter man en människa fångad av förtryckande strukturer utan vidare utrymme för motmakt, i ett Europa präglat av framväxande fascism och nationalism. I den här studien för jag in ett posthumanistiskt perspektiv, hämtat från Gilles Deleuze filosofi och Rosi Braidottis sociala teorier, för att undersöka människans möjligheter att göra politiskt motstånd genom utomparlame
The purpose of this thesis is to describe and analyze how the mining equipment producers on a global market manage to handle the changing conditions concerning customer value. Our approach has been a comparative analysis between two different sites in order to answer the purpose. The case studies at Metso Mining have been made through interviews and visits at two geographical markets, South Americ
In this paper, we replicate a study by de la Croix et al. (2013) to analyze the effects of population aging in Germany when implementing two different counterfactual pension systems. De la Croix et al. (2013) use a dynamic overlapping generations model to simulate population aging and its effects on the French economy. Calibrating and analyzing the same model as in de la Croix et al. (2013) with n
Abstract At face value, Nike’s Girl Effect campaign and Coke’s 5by20 project appear promising, with no potential complexities or ambiguities. However, analysts of corporate-led development have argued that such approaches to development draw on colonial stereotypes of girls and women as sexually and culturally constrained. This thesis aims to investigate these representations of girls and women in
Planar motion is an important and frequently occurring situation in mobile robotics applications. This thesis concerns estimation of ego-motion and pose of a single downwards oriented camera under the assumptions of planar motion and known internal camera parameters. The so called essential matrix (or its uncalibrated counterpart, the fundamental matrix) is frequently used in computer vision appli
Given a sensor network, TDOA self-calibration aims at simultaneously estimating the positions of receivers and transmitters, and transmitters time offsets. This can be formulated as a system of polynomial equations. Due to the elevated number of unknowns and the nonlinearity of the problem, obtaining an accurate solution efficiently is nontrivial. Previous work has shown that iterative algorithms
CONTEXT: A healthy lifestyle is the cornerstone of management in nonalcoholic fatty liver disease (NAFLD). However, the associations between dietary macronutrient composition and different aspects of NAFLD pathology are unclear and dietary recommendations for NAFLD are lacking.OBJECTIVE: This work aimed to evaluate the associations of dietary macronutrient composition with hepatic steatosis, hepat
INTRODUCTION: Tau positron emission tomography (PET) is a reliable neuroimaging technique for assessing regional load of tau pathology in the brain, but its routine clinical use is limited by cost and accessibility barriers. METHODS: We thoroughly investigated the ability of various machine learning models to predict clinically useful tau-PET composites (load and laterality index) from low-cost an
