Effects of secular growth and mergers on the evolution of metallicity gradients and azimuthal variations in a Milky Way-like galaxy

We analyzed the evolution of the radial profiles and the azimuthal variations of the stellar metallicities from the VINTERGATAN simulation of a Milky Way-like galaxy. We find that negative gradients exist as soon as the disk settles at high redshift, and are maintained throughout the long-term evolution of the galaxy, including during major merger events. The inside-out growth of the disk and an o

Energy Efficiency Potential of Second Homes Heated by Direct Electric Heating Located in Four Regions in Sweden

EU countries have committed to taking national measures to reduce the average energy use of residential buildings by 16% by 2030 and 20–22% by 2035. Each country has decided how to achieve this and which buildings to focus on. However, certain categories of residential buildings, including historical buildings but also second homes, may be exempt from these obligations. In Sweden, second homes con

Electrical Properties of Conductive Electric Roads

Given the global climate crisis, the electrification of road transport has accelerated in recent decades as a strategy to mitigate global greenhouse gas emissions, with the share of Battery Electric Vehicles (BEVs) increasing exponentially. While BEVs provide substantial environmental advantages during their operational phase compared to combustion-powered vehicles, they require an extensive charg

High-fidelity 3D live-cell nanoscopy through data-driven enhanced super-resolution radial fluctuation

Live-cell super-resolution microscopy enables the imaging of biological structure dynamics below the diffraction limit. Here we present enhanced super-resolution radial fluctuations (eSRRF), substantially improving image fidelity and resolution compared to the original SRRF method. eSRRF incorporates automated parameter optimization based on the data itself, giving insight into the trade-off betwe

The rise of data-driven microscopy powered by machine learning

Optical microscopy is an indispensable tool in life sciences research, but conventional techniques require compromises between imaging parameters like speed, resolution, field of view and phototoxicity. To overcome these limitations, data-driven microscopes incorporate feedback loops between data acquisition and analysis. This review overviews how machine learning enables automated image analysis

Super-resolution imaging pinpoints the periodic ultrastructure at the human node of Ranvier and its disruption in patients with polyneuropathy

The node of Ranvier is the key element in saltatory conduction along myelinated axons, but its specific protein organization remains elusive in the human species. To shed light on nanoscale anatomy of the human node of Ranvier in health and disease, we assessed human nerve biopsies of patients with polyneuropathy by super-resolution fluorescence microscopy. We applied direct stochastic optical rec

Sveriges regionala dynamik. Historiska trender och framtidens utmaningar

Regionalekonomiska skillnader och varierad befolkningsutvecklinghar under lång tid präglat Sveriges samhällsdynamik. Genom enhistoriskanalys från 1860-talet och framåt visar denna rapport hurregional ojämlikhet i Sverige tidvis har ökat och tidvis har minskat.Den ekonomiska tillväxten har sedan 1980 främst gynnat större regioneri ekonomisk- och befolkningsbemärkelse, medan mindre områdenhalkat eft

Clinical use of polygenic scores in type 2 diabetes: challenges and possibilities

Resulting from a combination of genetic and environmental factors, type 2 diabetes is highly heterogeneous in manifestation and disease progression, with the only common feature being chronic hyperglycaemia. In spite of vigorous efforts to elucidate the pathogenetic origins and natural course of the disease, there is still a lack of biomarkers and tools for prevention, disease stratification and t

Antibiotic prophylaxis and incidence of infection following elbow arthroplasty : a nationwide study

BACKGROUND AND PURPOSE: Periprosthetic joint infection (PJI) after elbow arthroplasty is a serious complication. Evidence of the best antibiotic prophylaxis for elbow arthroplasty is lacking. We aimed to investigate the regimens presently used in Sweden, incidence of PJI, and the bacteria most frequently found in elbow PJI.METHODS: A questionnaire was sent out to all Swedish units performing elbow

A key agent of societal change? : Supervisors as role models for postgraduate students in Uganda

Postgraduate education has been recognised as a key to bring about societal change. While further capacity building is imperative in this regard in East Africa (Wao et al., 2022), we will in this study focus on how supervisors function as important role models to their students (Brodin et al., 2020). We assume that supervisors’ own approaches to societal change affect their supervisor relationship

Sensuous Bodies : Theoretical and Empirical Perspectives on Disordered Eating

Kroppen har relevans för psykologi. Den är basen, alltid i bakgrunden av våra upplevelser, våra sinnestillstånd, och den är därmed alltid med i bakgrunden av psykopatologiska tillstånd. En bättre förståelse för kroppens betydelse för vår tillvaro och vårt varande är en första utgångspunkt. Ett huvudargument som förs i avhandlingen är att om psykopatologiska tillstånd som berör ens kroppslighet skaThe body holds relevance for psychology. The body is the basis, always in the background of our experiences, our states of mind, and therefore always in the background of psychopathological conditions.A better understanding of the body's significance is a first starting point. A main argument made in the thesis is that if we sincerely want to understand psychopathological states we need some basic

Parent-of-origin effects in the life-course evolution of cardiometabolic traits

AIMS/HYPOTHESIS: Cardiometabolic traits are heritable, and some display parent-of-origin effects, which indicates preferential inheritance from one parent or parental bias. Most studies of these phenomena have focused on adult populations. We aimed to investigate the heritability and parent-of-origin effects on cardiometabolic traits in a birth cohort with serial measurements to determine whether

Epigenome-wide association study of objectively measured physical activity in peripheral blood leukocytes

BACKGROUND: Few studies have explored the association between DNA methylation and physical activity. The aim of this study was to evaluate the association of objectively measured hours of sedentary behavior (SB) and moderate physical activity (MPA) with DNA methylation. We further aimed to explore the association between SB or MPA related CpG sites and cardiometabolic traits, gene expression, and

The Association Between Women's Perception of Birth During the Pandemic, Companion of Choice and Support From Health Professionals : A Cross-Sectional Study in 20 Countries in the WHO European Region

BACKGROUND: Mitigation measures implemented in response to the COVID-19 pandemic led to significant changes in maternity care across Europe, including restrictions on companions during labor and birth. This cross-sectional study explores the association between the presence of a companion of choice and a positive perception of the birth experience. Additionally, it explores the association between

Aspects of 18F-PSMA-1007 PET/CT in prostate cancer : Biokinetics, dosimetry, protocol and diagnostic accuracy

Overview: Prostate cancer (PC)is the most common cancer in Sweden, and the leading cause of cancer death. Positronemission tomography with x-ray computed tomography (PET/CT) is an important imagingmethod for many cancers. A group of PET radiopharmaceuticals known as PSMA(prostate specific membrane antigen) ligands has been introduced for imaging ofPC. This thesis investigates aspects of the ligand

The Aesthetic Authority of Law : Experiments with Legal Form

The legal form dictates the contours of law’s appearance. Texts are neatly divided into (often) numbered paragraphs. Pages must conform to specified layouts. Conventions regulate the use of fonts, punctuation and colours. Legal terms of art replace colloquial expressions. Human experiences enter legal texts only in mediated, sanitized forms. The dictats of legal form are all but incidental. They c
