Reliability in Ricean multiple-input-multiple-output (MIMO) channels is crucial for safety related vehicle-tovehicle (V2V) applications. Due to the time variability of vehicular communication channel, it is very significant to study the temporal evolution of channel characterization criteria. We present evaluation results of the temporal evolution of the spectral efficiency from channel sounder me

The COST2100 channel model is a reference channel model which provides dynamic multiple-input multiple-output channel responses for radio system simulations. In this paper, channels created by the COST2100 model were compared to channel measurements in order to understand behaviours of the model. Model parameters of the COST2100 model were derived by dynamic double-directional channel measurements

This paper presents delay spread, coherence bandwidth, and angle-of-arrival statistics derived from an extensive MIMO channel measurement campaign carried out at a central frequency of 2.6GHz. The measurement scenarios include indoor-indoor, indoor-outdoor and indoor-outdoor-indoor. The results are useful for analytical and performance studies of post-3G wireless communication systems such as femt

The paper unpacks the relationship between local culture and agency to enhance our understanding of local variations of agency. The paper studies two former old industrial places in Sweden; one place characterized by an entrepreneurial culture (Borås), the other with a company town culture (Kiruna). Both cases experienced structural crisis around 1970s. A study period of more than 30 years is used

During recent years new threats have accentuated the role of scientific experts for creating risk awareness, understanding, and advice for action or preparedness for informed risk decisions. Scientific experts are expected to engage in risk communication with stakeholders at various levels, not least the general public. Scientific experts exist in organizations where forms and goals may vary, as wDuring recent years new threats have accentuated the role of scientific experts for creating risk awareness, understanding, and advice for action or preparedness for informed risk decisions.

With a view to working toward urban sustainability goals, two Swedish research platforms, SLU Urban Futures at the University of Agricultural Sciences in Alnarp (SLU) and the Urban Arena at Lund University, launched Urban Forum, a transdisciplinary dialogue format, in 2019. Designed to foster exchange between practitioners and scholars in the spatial design fields the Forum convenes actors from pr

Here we study the influence of particle size on the formation of antiferromagnetic FexO subdomains and the emergence of exchange bias in novel ferrimagnetic Cr-substituted Fe3O4 nanoparticles generated using an aerosol technique based on spark ablation. Cooling in an applied magnetic field across the Néel temperature of the FexO subdomains results in significant shifts in the hysteresis loops, whi

BackgroundThe essential trace elements copper and zinc, and their ratio (copper/zinc), are important for maintaining redox homeostasis. Previous studies suggest that these elements may impact breast cancer survival. However, no epidemiological study has so far been conducted on the potential association between copper and copper/zinc levels and survival after breast cancer diagnosis. In this study

Background: Primary Sclerosing Cholangitis (PSC) is a hepatobiliary disease closely related to ulcerative colitis (UC). In PSC patients, colectomy has been linked to improved prognosis, especially following liver transplantation. This suggests an involvement of the gut-liver axis in PSC etiology. Objective: We aimed to investigate the association between colectomy and the risk of future PSC in an

Background and Aims: Inflammatory bowel disease [IBD] has been associated with spondyloarthritis [SpA], but population-based estimates are scarce. Here we compare the occurrence of SpA before and after a diagnosis of IBD with the general population, overall and by IBD subtype and age. Methods: We used a nationwide register-based cohort study of 39 203 patients diagnosed with IBD during 2006-2016,

Background: Real-world data on long-term outcomes of vedolizumab (VDZ) are scarce. Objective: To assess long-term outcomes (up to 3 years) of VDZ in treating inflammatory bowel disease (IBD). Design: A nationwide, prospective multicentre extension of a Swedish observational study on VDZ assessing Effectiveness And Healthcare resource utilization in patients with IBD (SVEAH). Methods: After re-cons

Tillgänglighet har blivit ett centralt begrepp i transportpolitiken. Begreppet har dock kommit att bli alltmer mångfacetterat och det förekommer en rad olika definitioner. Tillgänglighet anses bestå av tre olika delkomponenter: transportsystemet, markanvändningssystemet samt individen, där interaktionen mellan dessa tre delar anses väsentlig. Tillgång till informations- och kommunikationsteknik (I

Studiens syfte har varit att genom en litteratursammanställning ta reda på hur forskningsområdet har sett att Covid-19-pandemin kan bidra till varaktiga förändringar i resande och transporter. Flera trender etablerades eller förstärktes under pandemin, men det är svårt att med säkerhet avgöra om de kommer hålla i sig. Ett problem som vi har sett är att det finns för lite data för att utveckla nya

In Lexel (Case C-484/19), the Swedish interest deduction limitation rules were found to be in breach of article 49 of the TFEU on the freedom of establishment, as they presumed abusive practices even in respect of arm’s length-based transactions. The present article puts the case into context and highlights follow-up issues raised before lower Swedish tax courts in the context of loan transactions
