Understanding wireless channels is crucial for the design of wireless systems. For mobile communication, sounders and antenna arrays with short measurement times are required to simultaneously capture the dynamic and spatial channel characteristics. Switched antenna arrays are an attractive option that can overcome the high cost of real arrays and the long measurement times of virtual arrays. Opti

This thesis investigates the adoption of artificial intelligence (AI) solutions among architects in Sweden. Architects are currently experiencing headwinds and decreased demands for their services as increasing interest rates and a weak economy have contributed to a decline in construction activity. Simultaneously, advancements in AI have introduced a range of innovative technologies to the field

China’s financial actions along the BRI network has sparked a lot of controversies, one of these being the alleged usage of Debt Trap Diplomacy (DTD) in order to gain access to resources through debt relief that they otherwise would not be able to reach through traditional means. DTD practices can be considered part of the International Political Economy’s ‘blind spots’ due to their complexity and

Despite the so-called ‘great retreat’, in which people arguably are distancing themselves from the political sphere and civic engagement, the last two years has seen an upsurge in political activities. Outside the realms of institutionalised politics, i.e. political parties, lies a whole terrain of alternative political activities, including social movements and media institutions. Following the E

Shopping malls are a global phenomenon, and as such they reach a degree of local iconicity simply by being malls. One of the main roles shopping malls play in our everyday lives is nurturing social interactions. Shopping malls have been portrayed by many scholars as places where people go to practice consumer religion (Fiske, 1989; Ritzer, 1999; Zepp, 1997), prime temples which glorify consumption

Recent work from several laboratories has demonstrated that proteolytic mechanisms significantly contribute to the molecular interplay between Streptococcus pyogenes, an important human pathogen, and its host. Here we describe the identification, purification and characterization of a novel extracellular cysteine proteinase produced by S.pyogenes. This enzyme, designated IdeS for Immunoglobulin G-

OBJECTIVE: Mapping coreceptor epitopes used by the prototypic R5 and X4 strains, HIV-1BaL and HIV-1IIIB, in comparison with epitopes involved in the activation and signaling induced by the natural ligands, RANTES and SDF-1beta. DESIGN: Receptor hybrids between CCR5 and CXCR4 were constructed. METHODS: Using single-overlap and extension PCR, increasing portions of CCR5 were replaced with correspond

The aim of present study was to arrange an experimental rabbit model for IgA-nephropathy. To this purpose, an approach was attempted which was previously successfully applied in rabbits, aiming for induction of post-streptococcal glomerulonephritis (PSGN). To induce the nephropathy, we used two Streptococcus pyogenes strains of M4 and M60 serotypes which showed differential IgA-binding capacity me

GAD65 autoantibodies (GAD65Ab) are highly prevalent in type 1 diabetes, but their functional role in the pathogenesis of the disease and their relationship to T-cell reactivity to GAD65 is still unclear. We tested the hypothesis that GAD65Ab modulate presentation of GAD65 to T-cells. T-cell hybridoma T33.1, which recognizes the GAD65 274-286 epitope in the context of HLA-DRB1*0401, was incubated w

Neisseria gonorrhoeae is the etiological agent of gonorrhea, the second most common bacterial sexually transmitted infection worldwide. Reproductive sequelae of gonorrhea include infertility, ectopic pregnancy and chronic pelvic pain. Most antibiotics currently in clinical use have been rendered ineffective due to the rapid spread of antimicrobial resistance among gonococci. The developmental pipe
