This paper is concerned with model fitting in the presence of noise and outliers. Previously it has been shown that the number of outliers can be minimized with polynomial complexity in the number of measurements. This paper improves on these results in two ways. First, it is shown that for a large class of problems, the statistically more desirable truncated L-2-norm can be optimized with the sam
This thesis aimed to search for epidemiological evidence supporting the associations of type 2 diabetes mellitus (T2DM) with cancer and autoimmune diseases (ADs) by analysing several Swedish national registries. T2DM shares risk factors with cancer, such as obesity, diet, stress, and physical inactivity. However, it is unclear whether the associations with several types of cancers are due to share
Levels of total human kallikrein 2 (hK2), a protein involved the pathology of prostate cancer (PCa), could be used as a biomarker to aid in the diagnosis of this disease. In this study, we report on a porous silicon antibody immunoassay platform for the detection of serum levels of total hK2. The surface of porous silicon has a 3-dimensional macro- and nanoporous structure, which offers a large bi
Objective: To evaluate two commonly used forms of hand training with respect to influence on dexterity and cortical reorganization. Subjects: Thirty healthy volunteers (mean age 24.2 years). Methods: The subjects were randomized to 25 min of shaping exercises or general activity training of the non-dominant hand. The dexterity and the cortical motor maps (number of excitable positions) of the abdu
Hummingbirds are specialized hoverers for which the vortex wake has been described as a series of single vortex rings shed primarily during the downstroke. Recent findings in bats and birds, as well as in a recent study on Anna's hummingbirds, suggest that each wing may shed a discrete vortex ring, yielding a bilaterally paired wake. Here, we describe the presence of two discrete rings in the wake
Charred seed conglomerates of Linum usitatissimum (flax) and Camelina sativa (gold of pleasure) were found at UppAyenkra 2:25, a Roman Iron Age site in SkAyenne, southern Sweden. The conglomerates showed no mixing with each other, as they were almost pure flax and gold of pleasure respectively. Together with other archaeobotanical data from the site, they provide new evidence on the use, processin
The Japanese government managed to implement the Act on the Protection of Specially Designated Secrets (SDS) in late 2014, making it easier for government agencies to withhold information. The debate that was ignited by the SDS is central to this thesis. Existing research on the SDS can be characterized as a battle for truth, with a focus on the superficial effects of the law. In contrast, this pa
This article argues that the high level of protest activity in France is, at least partly, the result of distrust between the government and the trade unions, and that such distrust is inevitable in a society where unions are sometimes strong enough to mobilise against the government but not confident in their own future strength. This trust problem can be overcome if governments are willing to ma
The concept of Integrated Water Resources Management (IWRM) has enjoyed immense popularity and thus has been the preferred approach for river basin management. IWRM generally has a strong focus on rational choice, based on a technocratic conceptual interpretation of the conventional hydrological cycle. However, uncritical acceptance of IWRM runs the risk of blinding policy makers and academics for
Preeclampsia (PE) is a serious pregnancy complication that manifests as hypertension and proteinuria after the 20(th) gestation week. Previously, fetal hemoglobin (HbF) has been identified as a plausible causative factor. Cell-free Hb and its degradation products are known to cause oxidative stress and tissue damage, typical of the PE placenta. A1M (α1-microglobulin) is an endogenous scavenger of
Conclusion. The gentamicin-induced pathological alteration in the cochlear nucleus is not exclusively a secondary consequence of the damage in the cochlea. Instead, the toxic effect of gentamicin on the cochlear nucleus may occur simultaneously or even earlier than that on the cochlea. Objectives. To investigate the pathological alteration of cochlear nucleus neurons in guinea pigs following syste
This paper discusses importance of a strategic planning and design process when developing long-term space exploration missions both robotic and manned. The discussion begins with reviewing current and/or traditional international perspectives on space development at the American, Russian and European space agencies. Some analogies and comparisons will be drawn upon analysis of several internation
The filamentous fungus Hypocreajecorina (anamorph of Trichodermareesei) is the predominant source of enzymes for industrial saccharification of lignocellulose biomass. The major enzyme, cellobiohydrolase Cel7A, constitutes nearly half of the total protein in the secretome. The performance of such enzymes is susceptible to inhibition by compounds liberated by physico-chemical pre-treatment if the b
Popular Abstract in Swedish Fetma är ett världsomfattande hälsoproblem som drabbar rika och fattiga länder i samma utsträckning och leder till minskad förväntad livslängd. Detta är inte bara ett problem i sig utan för med sig ytterligare följdsjukdomar så som diabetes, hjärt- kärlsjukdomar, vissa former av cancer och artros. Det är en allmän uppfattning att den oroväckande ökningen av fetma under Obesity is one of the major health concerns that has reached epidemic proportions globally. It is generally believed to be a result of interactions between genetic and environmental factors. In this thesis we investigated the role of dietary factors in modifying the genetic susceptibility to obesity (papers I to III), studied the association between genetic susceptibility to obesity and weight gai
Electromagnetic induction measurements (EM) were taken in a saline gypsiferous soil of the Saharan-climate Fatnassa oasis (Tunisia) to predict the electrical conductivity of saturated soil extract (ECe) and shallow groundwater properties (depth, Dgw, and electrical conductivity, ECgw) using various models. The soil profile was sampled at 0.2 m depth intervals to 1.2 m for physical and chemical ana
