In this paper we establish a geometry-based stochastic ultra-wideband channel model for outdoor infostations scenarios. We statistically describe the location and strength of clusters of scatterers, as well as the shape and width of visibility and shadowing regions. We also separately model diffuse radiation (which cannot be explained by the scatterer components), and show that its fading statisti

The function of chronic brain machine interfaces depends on stable electrical contact between neurons and electrodes. A key step in the development of interfaces is therefore to identify implant configurations that minimize adverse long-term tissue reactions. To this end, we here characterized the separate and combined effects of implant size and fixation mode at 6 and 12 weeks post implantation i

A mobile DIAL (differential absorption lidar) remote sensing system has been employed in the monitoring of industrial pollutant emissions. Measurements of sulfur dioxide and mercury vapor were performed at nine different Swedish industrial plants within the framework of a control program commissioned by the Swedish Environmental Protection Agency. Total atmospheric fluxes of these species could be

Identification of cardiomyocyte nuclei has been challenging in tissue sections as most strategies rely only on cytoplasmic marker proteins(1). Rare events in cardiac myocytes such as proliferation and apoptosis require an accurate identification of cardiac myocyte nuclei to analyze cellular renewal in homeostasis and in pathological conditions(2). Here, we provide a method to isolate cardiomyocyte

The aim of this study was to compare the frequency of human leukocyte antigen (HLA) genotypes in 1-18-year-old patients with type 1 diabetes newly diagnosed in 1986-1987 (n = 430), 1996-2000 (n = 342) and in 2003-2005 (n = 171). We tested the hypothesis that the HLA DQ genotype distribution changes over time. Swedish type 1 diabetes patients and controls were typed for HLA using polymerase chain r

Context: Effect of GH therapy in short non GH deficient children, especially idiopathic short stature (ISS) has not been clearly established owing to lack of controlled trials until final height (FH). Objective: To investigate the effect of two GH doses compared with untreated controls on growth to FH in short children mainly with ISS. Design and Setting: A randomized, controlled, long-term multic

Detta är det första av tre inlägg för att ge perspektiv på IKT i matematik- undervisningen. Bakgrunden till inlägget är en nyligen släppt rapport från Skolverket, som visar att användningen av IKT är i stort sett lika låg i flera ämnen, som den var för tre år sedan. Det är, enligt rapporten, fortfarande ovanligt att eleverna använder datorer på lektioner i matematik. Det finns inte heller någon ty

Review of Markus Dahlberg (ed), “Sockenkyrkorna. Kulturarv och bebyggelsehistoria” (Stockholm 2008)

The social consequences of agrarian change have been widely debated. The traditional view of the lower classes becoming increasingly vulnerable due to the loss of access to resources has been met with the revisionist view that this change was counteracted by an increase in the volume and regularity of employment due to investments and new farming practices. This article address this issue by study

The article discusses the integration of the former Danish Skåne provinces in Sweden after 1658.

This study examined retirement decisions among people who had left working life before 65 years of age and those working beyond 65 years in an extended working life. The results were used to make a model about their considerations, weighting and decision making, and important factors and themes in working beyond 65 years of age or retiring before 65. The interviewees seemed to have considered and
