The annealing behaviour of swift heavy-ion tracks in apatite from different origins is studied as a function of their crystallographic orientation and the mineral composition. The tracks were generated by irradiating the apatite samples with 2.3 GeV Bi ions, which have a comparable rate of energy loss to fission tracks in this mineral. The track radius was investigated using synchrotron-based smal
Crystalline Ge and Si1−xGex alloys (x = 0.83, 0.77) of (100) orientation were implanted with 140 keV Ge− ions at fluences between 5 × 1015 to 3 × 1017 ions/cm2, and at temperatures between 23 °C and 200 °C. The energy deposition of the ions leads to the formation of porous structures consisting of columnar pores separated by narrow sidewalls. Their sizes were characterized with transmission electr
Heavy-ion irradiation of high-temperature superconducting thin films has long been known to generate damage tracks of amorphized material that are of close-to-ideal dimension to effectively contribute to pinning of magnetic flux lines and thereby enhance the in-field critical current. At the same time, though, the presence of these tracks reduces the superconducting volume fraction available to tr
In the process of shape transformation of metal nanoparticles (MNPs) embedded in dielectrics resulting from swift heavy-ion irradiation, key parameters such as the energy deposition threshold, the necessity of a molten track and the NP size have been identified for amorphous silicon dioxide. The extension of such parameters to other dielectrics is yet unclear. We present experimental evidence of t
The cylindrical nanoscale density variations resulting from the interaction of 185 MeV and 2.2 GeV Au ions with 1.0 μm thick amorphous SiNx:H and SiOx:H layers are determined using small angle x-ray scattering measurements. The resulting density profiles resembles an under-dense core surrounded by an over-dense shell with a smooth transition between the two regions, consistent with molecular-dynam
When a swift heavy ion (SHI) penetrates amorphous SiO2, a core/shell (C/S) ion track is formed, which consists of a lower-density core and a higher-density shell. According to the conventional inelastic thermal spike (iTS) model represented by a pair of coupled heat equations, the C/S tracks are believed to form via "vaporization" and melting of the SiO2 induced by SHI (V-M model). However, the mo
Ion tracks created in polycarbonate foils by irradiation with 2.2 GeV Au ions were characterized using a combination of small-angle x-ray and neutron scattering (SAXS/SANS) and Fourier transform infrared spectroscopy (FTIR). The ion tracks were found to consist of a cylindrical damage core with a radius of ∼2.5 ± 0.2 nm and a relative density approximately 5% below that of the pristine polycarbona
This chapter gives an introduction to the European Research Infrastructure Consortium (ERIC) – a European Union (EU) policy tool introduced in 2009 with the purpose to set up and operate collaborative Research Infrastructures by granting them a legal personality and qualities of an international organization. The shared responsibility between the member states and the EU in the research and innova
We present a systematic study of the evolution of chemically etched ion tracks formed in thermally grown a-SiO2 after irradiation with 1.1 GeV and 185 MeV Au ions. The irradiated material was subsequently etched with 2.5% hydrofluoric acid (HF) for different times yielding hollow conical shaped structures of various sizes. The characterisation of these structures was carried out by synchrotron-bas
BackgroundAs a result of several violent terrorist incidents, authorities in Sweden have shifted from previous approaches of being certain that it is safe for the ambulance service to enter the scene, to a one where “safe enough” is sufficient, potentially making it possible to save more lives. The aim was therefore to describe specialist ambulance nurses' perceptions of the new approach to assign
PURPOSE: To investigate factors related to omitted total body skin examination (TBSE) in skin cancer diagnostics while managing patients using teledermoscopy (TDS) in Swedish primary care.METHODS: 4,987 TDS referrals from primary care centers were analyzed to identify factors associated with failing to perform TBSE. Data collected included age, gender of patient and physician, and reason for a vis
(1) Background: This study examined the cross-sectional association between metabolic syndrome (MetS) status classified into three groups and daily physical activity (PA; step count and active minutes) using a wearable device in Japanese office workers. (2) Methods: This secondary analysis used data from 179 participants in the intervention group of a randomized controlled trial for 3 months. Indi
SF3B1 is the most mutated splicing factor (SF) in myelodysplastic syndromes (MDSs), which are clonal hematopoietic disorders with variable risk of leukemic transformation. Although tumorigenic SF3B1 mutations have been extensively characterized, the role of “non-mutated” wild-type SF3B1 in cancer remains largely unresolved. Here, we identify a conserved epitranscriptomic program that steers SF3B1
Varje suicid är en personlig tragedi och representerar dessutom en omfattande samhällelig förlust. Problematiken bakom suicid är mångfacetterad och insatser behövs inom många olika domäner i samhället, bland annat finns ett stort behov av nya hälso- och sjukvårdsstrategier. Hälso- och sjukvårdskuratorn med sin tvärvetenskapliga utbildning har möjlighet att bidra till ett multifaktoriellt perspekti
Starting from the assumption that citizenship is propertythat would be more valuable if it were transferable, the paper explores the idea of commodification of citizenship. The paper provides arguments in favor of commodification and recommendations to how the market for citizenships should be designed.

I den lilla medeltida byn Chianni i Toscana har olivodlingarna försörjt invånarna i flera hundra år. Varje höst reser markbiologen Håkan Wallander och hans vänner dit för att plocka oliver och sköta om de vackra träden.I Toscanas vänliga landskap kan de experimentera med olika odlingsmetoder i olivlunden. Lokala experter lär dem hur träden traditionellt ska beskäras och gödslas, men som jordforska
Epilepsy is one of the most common neurological disorders that is characterized by recurrent and unpredictable seizures. Wearable systems can be used to detect the onset of a seizure and notify family members and emergency units for rescue. The majority of state-of-the-art studies in the epilepsy domain currently explore modern machine learning techniques, e.g., deep neural networks, to accurately
