The advent of inexpensive consumer virtual reality equipment enables many more researchers to study perception with naturally moving observers. One such system, the HTC Vive, offers a large field-of-view, high-resolution head mounted display together with a room-scale tracking system for less than a thousand U.S. dollars. If the position and orientation tracking of this system is of sufficient acc

Background: The prevalence of obesity is increasing worldwide and prevention is needed. Whole grain has shown potential to lower the risk of obesity, cardiovascular disease and type 2 diabetes. One possible mechanism behind the benefits of whole grain is the gut fermentation of dietary fiber (DF), e.g. non-starch polysaccharides and resistant starch (RS), in whole grain. The purpose of the study i

In this paper we show how to convert the problem of estimating delay, slope and curvature of a parabolic event into a frequency estimation problem. Two dimensional data (time and offset) is converted into samples on a two-dimensional manifold embedded in a three-dimensional spaced. To conduct frequency estimation on this manifold we design general domain Hankel matrices and make use of a fixed poi

The main aim of this work is to construct several new families of proper biharmonic functions defined on open subsets of the classical compact simple Lie groups SU(n), SO(n) and Sp(n). We work in a geometric setting which connects our study with the theory of submersive harmonic morphisms. We develop a general duality principle and use this to interpret our new examples on the Euclidean sphere S^3

The Swedish system for public quality control of structural design of buildings is one of the most liberal in the world. The full responsibility for this is given to the client in a building project. Consequences of this system are discussed in this paper via a case study of a recent collapse of a three-storey building. A number of gross errors in design and execution are described followed by a d

We construct new proper biharmonic functions defined on open and dense subsets of the special unitary group SU(2). Then we employ a duality principle to obtain new proper biharmonic functions from the non-compact 3-dimensional hyperbolic space H^3.

Context: Extracorporeal shock wave lithotripsy (SWL) and ureteroscopy (URS), with or without intracorporeal lithotripsy, are the most common treatments for upper ureteric stones. With advances in technology, it is unclear which treatment is most effective and/or safest. Objective: To systematically review literature reporting benefits and harms of SWL and URS in the management of upper ureteric st

While smoking is a well-established risk factor for pancreatic cancer, the effect of smokeless tobacco is less well understood. We used pooled individual data from the Swedish Collaboration on Health Effects of Snus Use to assess the association between Swedish snus use and the risk of pancreatic cancer. A total of 424,152 male participants from nine cohort studies were followed up for risk of pan

Background: PSP is a neuropathologically defined disease entity. Clinical diagnostic criteria, published in 1996 by the National Institute of Neurological Disorders and Stroke/Society for PSP, have excellent specificity, but their sensitivity is limited for variant PSP syndromes with presentations other than Richardson's syndrome. Objective: We aimed to provide an evidence- and consensus-based rev

The received wisdom has long been that people in Europe reacted with great enthusiasm as war was approaching in August, 1914. However, scholars who have investigated the matter have found little evidence of enthusiasm. There was no unique “spirit of 1914,” and people in general were not happy about the prospect of war. This revisionist thesis is now the new orthodoxy and should as such be subject The received wisdom has long been that people in Europe reacted with great enthusiasm as war was approaching in August, 1914.

Today, there is an increased realization that engaging with Paralympic athletes offers the chance for healthcare professionals to work at the intersection of rehabilitation with sports and exercise medicine. The study of both injury and illness epidemiology in Paralympic sport is important, as findings may assist in the formulation of prevention strategies. A model for the systematic development o

Background: In order to contain public health care spending, European countries attempt to promote informal caregiving. However, such a cost reducing strategy will only be successful if informal caregiving is a substitute for formal health care services. We therefore analyze the effect of informal caregiving for people with dementia on the use of several formal health care services. Study design:

In order to explore consumer culture’s potential to change social relations, this investigation immerses into the growing consumer culture of foodies occupying the historically feminine space of domestic cooking. It offers a tentative theory on the entering of subordinate consumption fields in contexts where the entering is sanctioned by cultural authorities.

Co-presentation with both ANCA and anti-GBM antibodies is thought to be relatively rare. Current studies of such 'double-positive' cases report small numbers and variable outcomes. To study this further we retrospectively analyzed clinical features and long-term outcomes of a large cohort of 568 contemporary patients with ANCA-associated vasculitis, 41 patients with anti-GBM disease, and 37 double

The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs). RGCs are neurons that convey visual information from the retina to higher centers in the brain. If the optic nerve is transected (ONT), adult RGCs die by a form of cell death called apoptosis, and a general hypothesis is that neurotrophic factors can support the survival of injured neurons.With the intention to The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs).

Myeloid cells play a central role in atherosclerosis. We investigated the associations between the plasma levels of growth factors and chemokines that regulate myeloid cell homeostasis and function and the risk of first-time acute coronary events in middle-aged persons. Methods and Results-We measured baseline plasma levels of macrophage colony-stimulating factor monocyte chemotactic protein 1; C-

This is an overview paper that motivates and describes performed work done in the European Commission funded research project BASTION, which focuses on two critical problems of modern electronics: the No-Fault-Found (NFF) and CMOS ageing. New defect classes contributing to NFF have been identified, including timing related faults (TRF) at board level and intermittent resistive faults (IRF) at IC l
