Vi studerar stjärnors rörelser i Vintergatan med N-body simuleringar och stora astrometriska dataset från ESAs rymdteleskop Gaia. Vi identifierar två kinematiska populationer för vita dvärgar i Solens kvarter. Vi undersöker även ansamlade halon och avslöjar två nya hastighetsstrukturer. Slutligen, våra simuleringar visar att radiell migrering som en funktion av vertical action beror på diskmassa. We study stellar motions in the Milky Way with N-body simulations and large astrometric samples from ESA's Gaia mission. We identify two kinematic populations for white dwarfs in the Solar neighbourhood. We also investigate the accreted halo and reveal two new structures. Finally, our simulations show that radial migration as a function of vertical action depends on disc mass.

Based on interviews with three generations of professors reflecting upon their development as early career researchers in an outstanding research environment within the STEMfield, this study aimed to explore how they had coped with relationship conflicts in the environment, how this had an impact on their team socialisation, and how their development was framed by their supervisors’ leadership. Us

Phase contrast micro-CT is a powerful technique allowing imaging of soft tissue at synchrotrons or using lab- oratory sources. The use of contrast agents is a useful approach when imaging vascular structures. However, common x-ray contrast agents typically rely on heavy metals to increase absorption, which may affect the phase contrast and cause artifacts in the reconstructed volumes. Thus, utiliz

α-Synuclein (aSyn) is a 140 residue long protein present in presynaptic termini of nerve cells. The protein is associated with Parkinson's disease, in which case it has been found to self-Assemble into long amyloid fibrils forming intracellular inclusions that are also rich in lipids. Furthermore, its synaptic function is proposed to involve interaction with lipid membranes, and hence, it is of in

Traditionally entrepreneurship and small business research has been regarded as a practical and relevant research field, providing knowledge to be used to solve various societal problems. As the field is becoming more and more institutionalized in the academic system, scientific rigour in research has been emphasized at the expense of relevance. In the chapter the authors strives to show that prod

Battery thermal management (BTM) plays a significant role in the safety and reliability of autonomous underwater vehicles (AUV) at higher speeds. In this study, a nanoparticle/phase change material (nano-PCM) composite is proposed for the BTM of an AUV. The effects of nanoparticle loading percentage (φ = 5, 10, and 15%) and nanoparticle filling range (α = 30, 60, 90, and 120°) on the battery tempe

Animal migration is one of the most spectacular and visible behavioural phenomena in nature with profound implications for a range of ecological and evolutionary processes. Successful migration hinges on the ability to exploit temporary resources (e.g. food) and evade threats (e.g. predators) as they arise, and thus the timing of migration is often regarded as a dominant predictor of individual mi

Fe-N-heterocyclic carbene (NHC) complexes attract increasing attention as photosensitisers and photoredox catalysts. Such applications generally rely on sufficiently long excited state lifetimes and efficient bimolecular quenching, which leads to there being few examples of successful usage of Fe-NHC complexes to date. Here, we have employed [Fe(iii)(btz)3]3+ (btz = (3,3′-dimethyl-1,1′-bis(p-tolyl

For the longest of times, commerce and empire have been held to reside in perfect isolation from one another. Conceptually, peaceful commerce starkly opposed the discord of empires. In that same vein, political economy – the tool of commerce – was often considered the natural counterpart of warfare – the tool of empire. In many regards political economy was – and still is – considered an appealing

The high-pressure phase Na8BxSi46-x(3 < x < 5) is the first representative of a borosilicide crystallizing in the rarely occurring clathrate VIII type structure. Crystals with composition Na8B4Si42(space group I43¯ m; a = 9.7187(2) Å Pearson symbol cI54) were obtained at 5-8 GPa and 1200 K. The clathrate I modification exists for the same composition at lower pressure with a larger cell volume (Pm

The Swedish folklore collector Eva Wigström collaborated in the 1890s with the young artist and illustrator Gisela Trapp. They both lived in Helsingborg in the south of Sweden and shared many interests, despite a difference in age of about 40 years. In this article we are introduced to Wigström’s work as an author and folklore collector, and the cooperation between the two women is described. Wigs

Measurement and feedback control are essential features of quantum science, with applications ranging from quantum technology protocols to information-to-work conversion in quantum thermodynamics. Theoretical descriptions of feedback control are typically given in terms of stochastic equations requiring numerical solutions, or are limited to linear feedback protocols. Here we present a formalism f

Hydrogenated graphene (H-Gr) is an extensively studied system not only because of its capabilities as a simplified model system for hydrocarbon chemistry but also because hydrogenation is a compelling method for Gr functionalization. However, knowledge of how H-Gr interacts with molecules at higher pressures and ambient conditions is lacking. Here we present experimental and theoretical evidence t

BACKGROUND The enteric nervous system (ENS) is situated along the entire gastrointestinal tract and is divided into myenteric and submucosal plexuses in the small and large intestines. The ENS consists of neurons, glial cells, and nerves assembled into ganglia, surrounded by telocytes, interstitial cells of Cajal, and connective tissue. Owing to the complex spatial organization of several intercon

Background: Fear of falling (FoF) is very common in persons with late effects of polio (LEoP). An internationally recognized rating scale to assess FoF is the Falls Efficacy Scale-International (FES-I). Yet, there is limited knowledge about its measurement properties in persons with LEoP. Objective: To investigate the measurement properties of the FES-I (16-item version) and the short FES-I (7-ite

Ammonia (NH3) is regarded as a promising future carbon-free fuel but needs to overcome drawbacks including extremely low burning velocity in practical combustion apparatus. In this study, ozone (O3) additive is used to elucidate one of the mechanisms of potential flame enhancement method based on plasma-assisted combustion. The effects of ozone addition on the laminar burning velocity of premixed

Background: The mast cell-specific metalloprotease CPA3 has been given important roles in lung tissue homeostasis and disease pathogenesis. However, the dynamics and spatial distribution of mast cell CPA3 expression in lung diseases remain unknown. Methods: Using a histology-based approach for quantitative spatial decoding of mRNA and protein single cell, this study investigates the dynamics of CP

Three metabolite patterns have previously shown prospective inverse associations with the risk of aggressive prostate cancer within the European Prospective Investigation into Cancer and Nutrition (EPIC). Here, we investigated dietary and lifestyle correlates of these three prostate cancer-related metabolite patterns, which included: 64 phosphatidylcholines and three hydroxysphingomyelins (Pattern

The building industry has a major environmental impact in terms of global energy use, carbon emissions, resource use, and the production of waste. To reach ambitious international environmental goals, the building industry faces a need for large-scale change. Circular strategies for buildings include using building and materials longer through lifetime extension strategies, reuse, sharing, renovat
