Estimation of event related potentials with GSVD

An algorithm for estimation of event related signals dis-turbed by coloured noise, e.g. Evoked Potentials disturbed byEEG, has been investigated. The method is based on GeneralSingular Value Decomposition, GSVD, and estimates a singleEvoked Potential without averaging. There are no assumptionsabout the model for the EEG. The EP is described as a sum ofdamped sinusoids. The algorithm is tested with

Malaria, Immunity, and Immunopathology

Malaria is a disease spread by mosquitoes, and it is a major global cause of morbidity and mortality. Most of the deaths in malaria are caused by the Apicomplexan parasite Plasmodium falciparum. Immunity against the disease is dependent on repeated exposure, and it usually takes several years to develop. Antibodies against different antigens are an important part of immunity, but cellular immunity

Psychotropic drug use as indicator of mental health in adolescents affected by a plexus injury at birth : A large population-based study in Sweden

Chronic handicap in early life may have a long-term impact on children's psychosocial well-being. Here, we investigated whether Brachialis Plexus Birth Injury (BPBI)-an unpredictable injury at birth-is associated with worse mental health later on, as indicated by prescription and use of psychotropic drugs in adolescence. We explored further whether this association is different depending on socioe

OSL in NaCl vs. TL in LiF for absorbed dose measurements and radiation quality assessment in the photon energy range 20 keV to 1.3 MeV

The aim of this study was to determine the photon energy dependence of absorbed dose measurements, in a comparison of optically stimulated luminescence (OSL) in NaCl with thermoluminescence (TL) in LiF:Mg,Cu,P. The comparisons were made at exposure to ionizing radiation in the photon energy range 20 keV to 1.3 MeV. Specially designed dosemeter kits containing both NaCl and LiF were used under i) l

Optimization Methods for 3D Reconstruction : Depth Sensors, Distance Functions and Low-Rank Models

This thesis explores methods for estimating 3D models using depth sensors andfinding low-rank approximations of matrices. In the first part we focus on how toestimate the movement of a depth camera and creating a 3D model of the scene.Given an accurate estimation of the camera position, we can produce dense 3Dmodels using the images obtained from the camera. We present algorithms thatare both accu

Mental health and stigma-aspects of anti-stigma interventions

The chapter will give an overview of the history and actual status of three pertinent aspects of mental illness stigma: public stigma, discrimination and self-stigma, and the evidence for interventions to diminish stigma and discrimination. Stigma and discrimination are still important aspects of the lives of people with mental illness with negative consequences in a number of life domains. The st

Muscle function is associated with future patient-reported outcomes in young adults with ACL injury

BACKGROUND/AIM: Consequences of an anterior cruciate ligament (ACL) injury include worse patient-reported outcomes (PROs) and a decrease in activity level. Muscle function can be improved by targeted exercise. Our aims were to investigate cross-sectional and longitudinal associations among lower extremity muscle function and PROs after ACL injury.METHODS: Fifty-four participants (15 women, mean 30

Probiotic fruit beverages with different polyphenol profiles attenuated early insulin response

Background: Consumption of polyphenol-rich fruits and vegetables may improve postprandial glucose and insulin levels and hence promote well-being. Previously it has been observed that consumption of bilberry decreases the postprandial insulin demand. The intention with the present study was to compare the impact of different supplements with various polyphenol profiles, on the postprandial glucose

Hormonal contraception increases the risk of psychotropic drug use in adolescent girls but not in adults : A pharmacoepidemiological study on 800 000 Swedish women

The burden of depression and anxiety disorders is greater in women, and female sex hormones have been shown to affect mood. Psychological side effects of hormonal contraception (HC) are also a common complaint in the clinic, but few previous studies have investigated this subject. We therefore wanted to investigate whether use of HC was associated with adverse psychological health outcomes, and wh

Lean ApoM−/− Mice with Hyperactive Brown Adipose Tissue

In Cell Reports, Christoffersen et al. [1] demonstrate that sphingosine 1-phosphate (S1P) bound to apolipoprotein M (apoM) regulates the activity and mass of brown adipose tissue (BAT). They found mice lacking apoM to have hyperactive BAT with high triglyceride (TG) utilization, resulting in low white adipose tissue (WAT) mass and low body weight.

On the Modelling of Thermo-Viscoplasticity of Case-Hardening Steels Over a Wide Temperature Range

The aim of this work is the development of a thermodynamically consistent fully coupled thermo-viscoplastic material model for metals.The model is based on a split of the free energy into a thermo-elastic, a thermo-plastic and a purely thermal part and covers nonlinear cold-work hardening and thermal softening.Nonlinear temperature dependent effects are accounted for the elastic moduli, the plasti

Search for W W/W Z resonance production in ℓνqq final states in pp collisions at √s=13 TeV with the ATLAS detector

A search is conducted for new resonances decaying into a W W or W Z boson pair, where one W boson decays leptonically and the other W or Z boson decays hadronically. It is based on proton-proton collision data with an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of s=13 TeV in 2015 and 2016. The search is sensitive to

Formalizing Street Vendors: Regulating to improve well-being or to gain control?

Formalization, understood as gaining legal status to develop their businesses, is the mainstream policy to regulate the work of street vendors in most cities in the world. However, formalization policies are criticized by different scholars, and many vendors go back to the streets after formalization despite government efforts. To contribute to this long-standing debate, this chapter explores the
