Heterogeneous catalysts based on Single Atom Alloys (SAA) play a significant role in numerous technical processes. The fundamental working principles of these systems, however, remain poorly understood, especially the aspects related to the nanoscopic nature of bimetallic particles and the associated structure-reactivity relationships. In this study, we developed for the first time well-defined SA
Water is essential for life. This is particularly true for terrestrial insects, whose small size and high surface-area-to-volume ratios render them especially susceptible to dehydration. To overcome this challenge, insects have evolved sophisticated physiological mechanisms and behavioral strategies to maintain internal ion and water balance despite fluctuating environmental conditions. This chapt
The in vivo fate of mesenchymal stromal cells (MSCs), including their clearance, interaction with host tissues, and persistence, remains incompletely understood following systemic or local clinical administration to patients. Although immune-mediated clearance mechanisms, such as triggering of the instant blood-mediated inflammatory reaction, activation of coagulation and complement pathways, apop
Protein deletions are frequent among both disease-causing and tolerated variants. Several mechanisms at the DNA, RNA and protein levels can lead to deletions. Many deletions are misclassified in the literature and databases, especially when the mRNA is degraded by the cellular quality-control mechanism. We developed a novel predictor for sequence retaining protein deletions, i.e., variants that do
Background and purpose — Patient-specific instrumentation (PSI) in total knee arthroplasty (TKA) aims to improve implant alignment and clinical outcomes, but its effectiveness remains uncertain. We aimed to compare whether PSI was superior to conventional instrumentation (CVI) in TKA. The primary outcome was the Oxford Knee Score (OKS) at 2 years with assessments of additional clinical outcomes up
Aggressive tumours are defined by microenvironmental stress adaptation and metabolic reprogramming. Within this niche, lipid droplet accumulation has emerged as a key strategy to buffer toxic lipids and suppress ferroptosis. Lipid droplet formation can occur via de novo lipogenesis or extracellular lipid-scavenging. However, how tumour cells coordinate these processes remains poorly understood. He
Purpose – This article’s purpose is to examine how the balance between autonomy (stewardship) and control (principal-agent) has evolved over 2 decades through a comparative longitudinal study of university governance reforms in Denmark and Sweden. Design/methodology/approach – Employing a longitudinal comparative case study design, the study draws on extensive document analysis and applies a theor
Aerosol-cloud interactions (ACI) are a major source of uncertainty in climate science, critically affecting our ability to project near-term climate evolution and assess societal risks. These interactions influence effective radiative forcing, cloud dynamics, and precipitation patterns, yet remain insufficiently constrained due to limitations in observations, modeling, and process understanding. T
High-pressure blocking events are anticyclones that persist over a region for a long time. Such events prevent vertical mixing of air pollutants due to the subsidence inversion created by the anticyclone. This study investigates the relationship of aerosol concentrations during periods of high-pressure blocking events in southern Sweden for the rural location of Vavihill and the urban location of
Understanding variation in survival and reproduction is key for conservation and management of bird populations. By compiling and analysing data on hatching success (i.e. proportion of nests with at least one hatched egg) from Common Eider Somateria m. mollissima, Velvet Scoter Melanitta fusca and Red-breasted Merganser Mergus serrator, all breeding on a single island in the Baltic Sea, we demonst
This edited volume systematises jurisprudential analysis across various levels and elucidates largely unexplored processes of implementation, both at institutional, regional and national levels. By way of collecting such a diverse body of interpretations and practical experience, it strives to provide a comprehensive and practical article-by-article guide to the United Nations Declaration on the R
Background: Colorectal cancer (CRC) is a major health concern. In Sweden, a CRC screening program was implemented nationwide between 2019 and 2022. This study evaluated participation, colonoscopy adherence, and diagnostic outcomes for the program's first five years. Methods: The target group of screening was all residents 60–74 years old. Data were retrieved from SveReKKS, the Swedish national qua
Natural selection has produced diverse vision systems, from simple patches of photoreceptors to complex camera eyes, representing just one set of evolutionary outcomes. Computational evolution offers a way to systematically test hypotheses, isolate individual factors, and ask the “why” questions behind vision. We recreate vision evolution by coevolving eyes and behaviors in embodied agents and use
Forest Canopy Height (FCH) is one of the key variables for understanding forest structure distribution and growth. Remotely sensed data such as the NASA Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) ATL08 provides accurate FCH measurements; however, its point-based nature limits spatial continuity. This study addresses the challenge by generating a continuous FCH map over the West Usambara
Background Assessment of myocardial sympathetic innervation with iodine-123-metaiodobenzylguanidine ([123I]mIBG) scintigraphy is conventionally performed by determining the heart-to-mediastinum ratio (HMR) on planar images. This study aimed to investigate the feasibility of determining HMR from reprojected [123I]mIBG planar images derived from tomographic data by a ring-configured cadmium-zinc-tel
The complex and varied relationship found in intermolecular interactions within the photo-active layers plays a decisive role in determining the photovoltaic energy conversion and overall device performance of organic solar cells (OSCs). Among different approaches, the ternary blend strategy serves as an effective technique to control the morphology within the active layer in OSCs. In this work, P
Cancer-associated fibroblasts (CAFs) are central architects of the tumor microenvironment (TME), influencing cancer progression, therapeutic response, and immune regulation. This thesis explores CAF heterogeneity and functional specialization in breast cancer through integrated single-cell transcriptomics, spatial proteomics, and functional studies.High-resolution analysis of murine and human data
Hepatitis A virus (HAV) remains a preventable cause of acute viral hepatitis, with an estimated 159 million new infections and 39 000 deaths in 2019. Although improved care and hygiene reduced deaths, global incidence rose by approximately 4%, driven by increased symptomatic cases and population growth. The availability of safe and highly immunogenic vaccines and the absence of chronic carriage ma
