BACKGROUND: Recent advances in disease-modifying treatments highlight the need for accurately identifying individuals in early Alzheimer's disease (AD) stages and for monitoring of treatment effects. Plasma measurements of phosphorylated tau (p-tau) are a promising biomarker for AD, but different assays show varying diagnostic and prognostic accuracies. The objective of this study was to determine

This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. The algorithm tackles the near-far problem by using an iterative SIC, where for each receivedThis thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT).

Freshwater ecosystems are under multiple threats in modern times such as water extraction for human consumption, industries and agricultural activities, water contamination and habitat destruction for example. At the same time the biodiversity of these ecosystems are often poorly studied, especially in arid countries such as Iran. In this work, we study one of the ecologically important members of

We analyze the development of biodiversity offsetting governance through a research-weaving approach. Here, we combine information from a systematized review of the literature and a qualitative analysis of the institutional developments in different world regions. Through this triangulation, we synthesize and map the different developmental streams of biodiversity offsetting governance around the

The purpose of this paper is to describe the design of a multivariable control law for a hot plate mill. The design is performed on models adapted to the plate mill at The Danish Steel Work Ltd. The model for the rolling mill is divided into nonlinear models for the hydraulic systems performing the thickness control and a multivariable linear model for the rolling stand. The parameters of the mode

Itch is a common symptom, but there is limited evidence on the prevalence of itch in children. The aim of this study was to assess the prevalence of itch in schoolchildren. A questionnaire was developed by experts in the field and based on a literature search. The questionnaire was applied in a pilot study of 25 consecutively selected paediatric patients and their parents. It confirmed the high co

The increase in average seasonal temperatures has an impact in the occupational field, especially for those sectors whose work activities are performed outdoors (agricultural, road and construction sectors). Among the adaptation measures and solutions developed to counteract occupational heat strain, personal cooling garments represent a wearable technology designed to remove heat from the human b

Climate change is adversely impacting the burden of diarrheal diseases. Despite significant reduction in global prevalence, diarrheal disease remains a leading cause of morbidity and mortality among young children in low- and middle-income countries. Previous studies have shown that diarrheal disease is associated with meteorological conditions but the role of large-scale climate phenomena such as

Review-essay on ArkDes exhibition on Sigurd Lewerentz.

Our understanding of the present is informed by the past and the future as ideas about where we are right now are shaped by our memories of where we have been and our expectations about where we are going. This paper explores how the understanding of the COVID-19 pandemic was influenced both by experiences from past pandemics and predictions about the present. The paper focuses on the Swedish Publ

COVID-19-pandemins första våg präglades av stor osäkerhet kring den nya sjukdomen och experter världen mobiliserade för att kartlägga den nya sjukdomen, hastigheten i dess spridning och dess dödlighet. På grund av dessa osäkerheter blev epidemiologiska modeller en viktig resurs i arbetet med att bemöta och hantera pandemin. Genom att modellera dess troliga förlopp och påverkan skapade epidemiologi

This study addresses a one-to-one relation between articulation and acoustics at segment boundaries. The study focuses on Swedish word accents and how a rising or falling tone affect vowel segment duration. The paper explains how segment boundaries are a result of rapid movements of the articulators. In the acceleration profile, this is identified as peak acceleration, which can be measured. The t

Room temperature oxygen hydrogenation below graphene flakes supported by Ir(111) is investigated through a combination of X-ray photoelectron spectroscopy, scanning tunneling microscopy, and density functional theory calculations using an evolutionary search algorithm. We demonstrate how the graphene cover and its doping level can be used to trap and characterize dense mixed O-OH-H2O phases that o

We used diblock poly(acrylic acid)-b-poly(2-dimethylamino ethyl methacrylate) (PAA-b-PDMAEMA) polyampholytes to prepare core-shell complexes with ionic surfactants. The dispersions have been characterized by means of small-angle X-ray scattering (SAXS), cryogenic transmission electron microscopy (Cryo-TEM), dynamic light-scattering, and zeta potential methods. Using cationic or anionic surfactants

According to religious fictionalism, a non-believer can participate in religious life by playing a game of make-believe. Considering how games of make-believe build on imagination and pretence, I argue that religious fictionalism requires the non-believing participant to engage in role-playing. Turning to the literature on role-playing games, I demonstrate how religious fictionalism conforms to a

Background: Transit Oriented Development (TOD) is key to the success of public transport and for sustainable urban and regional development. Previous research has often focused on delivering TOD in urban areas with high population and building densities. This highlights the need to broaden the scope of TOD approaches to also include less densely populated areas located outside the immediate urban

This study presents an ethnographic exploration of subjective experiences relying on different historicizations and the ways they inform the connections between law and justice in Northern Kurdistan. By analyzing law and justice as ethnographic objects whose forms and functions are contingent upon being named and attributed meanings, inquiries focus on various historicizations/spatializations in N

The thesis studies a European Union legal form for organisation from the perspective of EU law and Swedish law on associations (associationsrätt). The legal form in focus is the European Research Infrastructure Consortium (ERIC), which was introduced by Council Regulation (EC) No 723/2009 of 25 June 2009 (the ERIC Regulation). The ERIC legal form allows states and intergovernmental organisations t
