Context: Age-related reduction of serum testosterone may contribute to the signs and symptoms of aging, but previous studies report conflicting evidence about testosterone levels and male mortality. No large prospective cohort study has determined a possible association between serum estradiol and mortality in men. Objective: The main objective was to examine the association between serum testoste

The problem with increasing test application time for testing core-based system-on-chip (SOC) designs is addressed with test architecture design and test scheduling. The scan-chains at each core are configured into a set of wrapper-chains, which by a core wrapper are connected to the test access mechanism (TAM), and the tests are scheduled in such a way that the test time is minimized. In this pap

The purpose was to study potential age ‐ related changes in the circulatory system via heart rate variability (HRV) by gradually lowering ambient temperature (0.2°C/min) from thermoneutral (32 C°) towards cold (18 C°). ECG was recorded from a young (31 years) and from an older subject (78 years), both males. During the tests, brachium blood pressure (BP) was recorded. During the cooling, BP increa

Prematurely born children have affected visual functions at school age. Optical coherent tomography (OCT) has shown morphological changes in the retina, suggesting a disturbance in normal retinal development in these children. The aim of this study was to examine retinal function with fullfield electroretinogram (ffERG) in school-aged children born prematurely and compare with children born at ter

Popular Abstract in Swedish I ett väderälskande land som Sverige finns det väl ingen som inte är bekant med den väderkarta som ger oss information om hur prognosen för den närmaste tiden ser ut? Många av oss tittar dagligen på väderrapporten och låter den hjälpa oss att bestämma om vi ska cykla eller ta bussen, sätta på grillen eller laga mat i ugnen. Genom enkla visualiseringar i form av sol, regWith the aid of modern computer technology the application of visualization and simulation technology has become increasingly important in today’s society. Through computer modelling it is possible to experience, understand and explore environments, systems or objects in two or three dimensions and to see, hear and sometimes tangibly feel them. It may be environments or objects that do not yet exi

Detta är en förstudie genomförd på uppdrag av Post- och Telestyrelsen av förmedlingstjänster för döva och hörselskadade människor. Mycket talar för att det behövs fördjupade studier, men det går att peka på vissa tämligen uppenbara spår att vidareutveckla

BACKGROUND: The extent of site and tissue-associated immune privilege is of great interest in transplantation experiments involving the CNS. In the present paper we have explored neuroretinal immune privilege by transplantation to a non-immune privileged site. METHODS: Fetal and adult full-thickness rabbit neuroretinal grafts were placed in the subconjunctival space of immunocompetent rabbit hosts

Background and Objectives Antibodies to antigens in the Kell blood group system, especially anti-KEL1, are involved in both haemolytic disease of the newborn and foetus and haemolytic transfusion reactions. Correct typing results are important and discrepancies between serologic and genetic typing must be resolved. Here, we describe the investigation of three healthy individuals who were initially

Popular Abstract in English The ultimate goal of computer vision is to make computers "see" like humans do. Toward this goal, one essential step is to enable computers to perceive a three-dimensional (3D) space as in the real world. In this thesis, we investigate the problem of reconstructing a 3D scene model from ordinary two-dimensional (2D) images. More specifically, given a set of images of thThis thesis is focused on geometric computer vision problems. The first part of the thesis aims at solving one fundamental problem, namely low-rank matrix factorization. We provide several novel insights into the problem. In brief, we characterize, generate, parametrize and solve the minimal problems associated with low-rank matrix factorization. Beyond that, we give several new algorithms based o

The empirical-bias bandwidth selector (EBBS) is a method for data-driven selection of bandwidths for local polynomial regression. It is a bandwidth selection method for estimation of the mean-function and its partial derivatives of any order as well as for estimation of the variance-function. Moreover EBBS allows for univariate as well as multivariate predictor variables. In this paper we introd

This is the first study indicating an association between gradually diminished risk of fractures and years of increased physical activity. Our results could imply great benefits not only for the individual but also for the healthcare burden and cost of society.

Popular Abstract in English Consumption of multimedia content is one of the main tasks we perform in our day-to- day lives, such as listening to music on an iPod or watching the news from an online steaming service. As technology has evolved and enabled easier access to different content (basically access anything anywhere), our consumption has grown. In only the last decades we have evolved from Multimedia has become one of the cornerstones of our 21st century society and, when combined with mobility, has enabled a tremendous evolution of our society. However, joining these two concepts introduces many technical challenges. These range from having sufficient performance for handling multimedia content to having the battery stamina for acceptable mobile usage. When taking a projection of w

Purpose. To create a retina consisting mainly of photoreceptors for future use as donor tissue in retinal transplantation. Methods. Fetal full-thickness neuroretinas from Sprague Dawley rats 17 (E17) or 20 (E20) days post conception were placed in culture for 7 or 14 days. Explants and age-matched control retinas were examined by light microscopy and with a panel of immunohistochemical markers lab
