Today, the car industry has become one of the greatest users of both wireless and cellular technologies and is increasingly dependent especially in the area of wireless communication. Communication among vehicles is offering a lot of benefits and has testified improvement on safety, efficiency and possible automation of the traffic. A lot of research has been focused on measurement campaigns, by i
Fifteen million people lose their lives to stroke and cancer every year. This amounts to one in every four deaths worldwide, making these among the deadliest diseases affecting humankind. Fruitful attempts at containing stroke- and cancer-related mortality hinge on early detection. Diffusion MRI (dMRI) is an imaging modality that is sensitive to tissue microstructure, and therefore unveils tissue
The use of factor-augmented vector autoregression (FAVAR) models has become increasingly popular in the literature of empirical macroeconomics. This paper sheds light on the different factor estimation methods that are available to researchers. More specifically, this paper examines the widely used principal component method but also the computationally simpler common correlated effects method as
Objective: The objective of this study was to compare health-related quality of life (HRQoL) and work productivity in axial SpA (axSpA) and non-axSpA patients with chronic back pain of <2 years. Methods: Baseline and 2-year data for patients included in the SPondyloArthritis Caught Early cohort were analysed. HRQoL was assessed by the physical (PCS) and mental component summary (MCS) scores of the
Nomenclature for the disease widely known as Sjögren syndrome has proven unsatisfactory. Patients have perceived ‘syndrome’ as indicative of a vague collection of symptoms, prompting the Sjögren’s Foundation to abandon the term. Furthermore, the traditional distinction between ‘primary’ and ‘secondary’ forms fails to account for the complex interplay between overlapping autoimmune diseases. Follow
The lung is a vital and dynamic organ that serves as a critical first barrier to environmental stimuli and facilitates gas exchange from birth until death. Developmental or genetic defects that impair lung function severely impact quality of life. Minor defects present in early life increase the likelihood that patients will develop chronic lung diseases in adulthood that have no cure. Current the
Membrane proteins are important building blocks for several biochemical processes. The difficulty with membrane proteins is that they tend to be lowly expressed and can be difficult to manage. Therefore, membrane proteins are studied to a lesser extent than soluble proteins. Since membrane proteins are intrinsically hydrophobic, their purification and structural determination critically rely on so
MicroProteins are small, separately expressed parts of a larger protein and able to interfere with the full-length protein’s function. To enable modulation of hormone perception, microProteins were designed from the ethylene, cytokinin and gibberellin receptors. The protein isoforms designed to function as microProteins were overexpressed in Arabidopsis. Overexpression of a shortened gibberellin r
Green ammonia, produced from renewable hydrogen, is emerging as an important energy carrier and decarbonized fertilizer alternative. However, its production is highly energy-intensive, making process efficiency critical to its commercial viability. This study investigates how targeted heat integration can enhance the energy and cost efficiency of green ammonia production based on a 200 MW PEM elec
Micro- and nanoscale pollutants dispersed at low concentrations in the environment pose increasing threats to human health and ecosystems. However, investigating the properties of individual particles remains challenging because conventional characterization methods mainly rely on ensemble measurements. Optical tweezers provide a promising approach for single-particle trapping and open new possibi
The city is a place where different activities take place side by side. The private next to the public, the sacred next to the everyday. For this, a rich variety of spaces is required - fronts and backs, insides and outsides, large and small, common and private. A spatial ecology of rooms, streets, passageways, and courtyards, relating and dependent on each other. Both general and specific. What m
This master thesis study is a preliminary investigation of the Säveån River as part of the Swedish Geotechnical Institute’s (SGI) landslide risk assessment project. The main objectives include building a hydrodynamic model for the river, estimating sediment transport along the river, assessing the implications for erosion and bank stability and evaluating climate change effects on sediment transpo
Objective To investigate the contemporary presentation of pituitary metastases. Patients Thirty-eight patients diagnosed with pituitary metastases from 1996 to 2018 in Sweden. Methods Pituitary metastases were confirmed by histopathology (n = 27) or considered highly likely according to radiological findings, including rapid tumor progression (n = 11). Medical records were reviewed and sellar imag
Aims. We have measured and calculated lifetimes of high lying levels in Nb II, and derived absolute transition probabilities by combining the lifetimes with experimental branching fractions. Methods. The lifetimes were measured using time-resolved laser-induced fluorescence in a two-photon and two-step excitation scheme. The branching fractions were measured in intensity calibrated spectra from a
Objective: In Sweden complications after radical cystectomy have been reported to the nationwide population-based Swedish Cystectomy Registry since 2011. Here, validation of the reporting was assessed in two healthcare regions. Materials and methods: Complications were ascertained from patient records by a third party not involved in the care delivered to 429 randomly selected patients from 949 wh
BACKGROUND: Ethiopia is one of the sub-Saharan African countries most affected by HIV/AIDS. However, the country lacks data describing the extent of the epidemic among people who inject drugs (PWID). Thus, a bio-behavioural study was conducted in 2015 to generate strategic information on the magnitude of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis and related risk behaviours am
Peripheral artery disease (PAD) is caused by atherosclerosis and associated with an increased risk of leg amputation, cardiovascular disease, and death. A healthy diet has been shown to reduce the risk of cardiovascular events, but relationships between diet, fiber intake, and incidence of PAD are virtually unknown. The aim was to investigate the long-term impact of diet on the development of PAD
Background: Pathological Q-wave (QW) in the electrocardiogram (ECG) before primary percutaneous coronary intervention (primary PCI) is a strong prognostic marker in patients with ST-segment elevation myocardial infarction (STEMI). However, current binary QW criteria are either not clinically applicable or have a lack of diagnostic performance. Accordingly, we evaluated the association between dura
The European Union is often criticized for its democratic deficit. This criticism has led to a process of including civil society in European governance through consultations, round table discussions and civil dialogue. These steps of inclusion have been oriented towards organized civil society. This study explores the European Citizens’ Initiative (ECI) a new tool for participation available to a
