Purpose: The mean diffusivity (MD) is sensitive to the microstructure of the cortex. However, partial volume effects with CSF and white matter (WM) may obscure pathology-related alterations. This work investigates both existing approaches and a novel approach for reducing partial volume effects. Theory and Methods: A bias in MD arises due to partial volume effects, higher-order terms, and the nois
Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind
BACKGROUND: Most COVID-19-related deaths and hospitalisations occurred among older people. Natural outdoor environments influence health outcomes, but the evidence of their effect on COVID-19 outcomes among older adults is limited. This study aimed to investigate associations between residential natural outdoor environment and COVID-19-related deaths or hospitalisations among community dwellers ag
Dopaminergic medication used in disorders like Parkinson's disease (PD) and restless legs syndrome can cause impulsive-compulsive behaviour (ICB), often with strong negative effects on patients' quality of life. This narrative review presents translational evidence on iatrogenic ICB, taking findings from epidemiological, clinical, neuroimaging and preclinical studies into consideration. Epidemiolo
Climate change accelerates the global hydrological cycle, which has escalating impacts on human health and the socioeconomic development. However, many existing Earth system models neglect the more complex processes of topography-driven vegetation–surface–groundwater interactions, thereby failing to accurately capture climate-hydrological responses. To address this gap, we integrate the three-dime
Through Arctic amplification, global climate change is projected to disproportionally affect high-latitude environments. Additionally, the geographical heterogeneity and complex terrain of mountains promote climate-driven ecological change on fine spatial scales. We used a high-resolution convection-permitting regional climate model (HCLIM) and a state-of-the-art dynamic vegetation model (LPJ-GUES
Anthropogenic land use and land cover changes (LULCC) have a large impact on the global terrestrial carbon sink, but this effect is not well characterized according to biogeographical region. Here, using state-of-the-art Earth observation data and a dynamic global vegetation model, we estimate the impact of LULCC on the contribution of biomes to the terrestrial carbon sink between 1992 and 2015. T
Realistic depictions of past land cover are needed to investigate prehistoric environmental changes, effects of anthropogenic deforestation, and long-term land cover-climate feedbacks. Observation-based reconstructions of past land cover are rare, and commonly used model-based reconstructions exhibit considerable differences. Recently, Pirzamanbein et al. (2018, 10.1016/j.spasta.2018.03.005, Spati
Traditionally, city commerce has always had a strong foothold in Swedish cities. However, in recent years the city commerce has experienced a weaker growth in comparison with external shopping and e-commerce. While the external shopping sector is experiencing competition from its own sector and e-commerce and struggles with an over-supply of malls it’s still a tough competitor to city commerce. De
Populärvetenskaplig sammanfattning: Examensarbetet syftar till att undersöka hur klimatiska förändringar och mänskligt utnyttjande av marken har påverkat fluviatila våtmarker (våtmarker i anslutning till rinnande vatten) i Bräkneåns dalgång i mellerst Blekinge. Få liknande undersökningar av fluviatila våtmarker har tidigare gjorts i Skandinavien, varför det är av intresse att ytterligare undersökaThe objective of the present investigation was to study how climatic changes and human impact may have affected fluvial wetlands in a river system. There are few earlier investigations in Scandinavia of that kind. Palaeoecological and palaeohydrological investigations were carried out in two fluvial wetlands located in the valley of the river Bräkneån. The main site Björkeryd is situated somewha
Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E.coli strain was made in the current work in order to increase the understanding of shikimic acid production and identify mean
In this paper we construct a hierarchical model for spatial compositional data which is used to reconstruct past land-cover compositions (in terms of coniferous forest, broadleaved forest, and unforested/open land) for five time periods during the past 6000 years over Europe. The model consists of a Gaussian Markov Random Field (GMRF) with Dirichlet observations. A block updated Markov chain Monte
Carbon storage dynamics in vegetation and soil are determined by the balance of carbon influx and turnover. Estimates of these opposing fluxes differ markedly among different empirical datasets and models leading to uncertainty and divergent trends. To trace the origin of such discrepancies through time and across major biomes and climatic regions, we used a model-data fusion framework. The framew
Resolution of interference between competing memories is often critical for remembering. This study employed multivariate pattern analysis (MVPA) of electroencephalographic (EEG) data to investigate the temporal dynamics of retrieval competition and competition resolution. Competition between memories was created through the AB/AC interference paradigm.

Det saknas en kritisk inställning till storytelling i den litteratur som existerar både för corporate storytelling och storytelling inom extern marknadsföring. Det mesta av den information som finns att tillgå har en positiv och okritisk inställning till storytelling och tar inte hänsyn till speciella omständigheter såsom i vilket syfte man använder det samt hur det påverkar försäljningen av de pr
Childhood cancer aetiology is poorly understood and is considered to originate in utero and early postnatal life. In this study, we investigated perinatal characteristics as potential risk factors by performing a population-based case-control study, including 1340 cancer cases diagnosed < 19y and born between 1989–2021 in southern Sweden, and 13400 controls matched by sex, year, and municipality o
