Chemical abundances of cobalt (Co; Z = 27) and copper (Cu; Z = 29) in bulge and halo stars are presented and compared with chemical evolution models. The aim is to distinguish if Co and Cu are dominantly produced by neutron-capture or the alpha-rich freeze-out processes. Neutron-capture can be identified by a secondary behaviour in the [X/Fe] vs. [Fe/H] plot, and alpha-rich freeze-out would give r
Aim: The degree to which species' niches remain stable over space and time–the niche conservatism hypothesis–is critical for predicting species' responses to environmental change. Tests of this hypothesis typically focus on changes in niche centroids and boundaries. An outstanding question is whether species' environmental associations differ within the interior of their niche space–that is, acros
Fuel cell hybrid electric vehicles (FCHEVs) are a promising solution for decarbonizing heavy-duty transport by combining hydrogen fuel cells with battery storage to deliver long range, fast refuelling, and high payload capacity. However, many existing simulation models rely on outdated fuel cell parameters, limiting their ability to reflect recent technological improvements and accurately predict
Background: Most actinide nuclides fission asymmetrically. A common explanation was that this division benefited from leading to fragments in the vicinity of the doubly magic 132Sn. It was tacitly assumed that lighter nuclides would all fission symmetrically because a similar situation could not occur there. However, a weakly asymmetric mass distribution was found for some preactinides at energies
Introduction. The sixth edition of the Transatlantic Orthopedic Surgery Webinar was held on March 3rd 2025, focusing on the comprehensive management of neuromuscular scoliosis in children with cerebral palsy (CP). The event brought together leading experts from Europe, North America, and Australia, representing centers of excellence in pediatric orthopedics and neuromuscular care. The initial sess
Achieving a robust ignition with minimal spark plug wear is challenging in heavy duty engines fueled with gaseous fuels like biogas and hydrogen. Thermal energy deposition from the spark to the gas was studied in a 10.9 milliliter custom-built spark calorimeter. An AC capacitive ignition system was used along with a dual-nickel standard J-gap spark plug and the influence of multiple physical and e
Objectives: To analyze device designs, similarities and overlaps of custom-made fenestrated arch endografts intended for mid/distal arch thoracic endovascular aortic repair. Materials and Methods: A multicenter cross-sectional study analyzing custom-made anonymized graft plans was performed. Graft plans were included from a cohort of mid/distal aortic arch repairs using custom-made fenestrated aor
Background Colorectal polypectomy is operator dependent, with variable rates of complete resection. The currently available assessment tools do not provide specific competency-based evaluation of provider technique. We aimed to validate the Global Polypectomy Assessment Tool (GPAT), a novel competency assessment tool for colorectal polypectomy. Methods GPAT was derived from the ESGE Curriculum for
Background: The aim of heart transplantation is prolonged survival and improved quality of life. Chronic pain is a common and distressing symptom after heart transplantation. To our knowledge, there are no person-centred interventions aimed at chronic pain and symptom distress after heart transplantation. The aim was to assess the feasibility and acceptability of systematic, person-centred symptom
Introduction: Worldwide, exposure to sexual violence has widespread consequences for survivors’ health and for their communities. There is still insufficient understanding of how to design support and care services for survivors in a multiorganizational context. This study aims to map and explore support and care for survivors of sexual violence from a multiorganizational perspective in Sweden, to
Plasma phosphorylated-tau 217 (p-tau217) is currently the most promising biomarker for reliable detection of Alzheimer's disease pathology. Various p-tau217 assays have been developed, but their relative performance is unclear. We compared key plasma p-tau217 tests using cross-sectional and longitudinal measures of amyloid-β (Aβ)-PET, tau-PET and cognition as outcomes and benchmarked them against
Background: Early evidence suggests beta-blockers may have a disease-modifying effect in hereditary haemorrhagic telangiectasia (HHT). We aimed to assess the efficacy of oral propranolol is reducing severity of HHT-related epistaxis. Methods: A randomised, double blind, placebo controlled clinical trial was conducted in adults with HHT experiencing epistaxis. Subjects were randomly assigned to rec
Background and Aims. While the rationale for coronavirus disease 2019 (COVID-19) vaccination is to reduce complications and overall mortality, some cardiovascular complications from the vaccine itself have been demonstrated. Myocarditis and pericarditis are recognized as rare acute adverse events after mRNA vaccines in young males, while evidence regarding other cardiovascular events remains limit
In multiple myeloma (MM), advancements in treatments and toxicity management have enhanced survival rates. This, coupled with shifting age demographics in MM, necessitates an updated assessment of infection risks in MM patients compared to the general population. Using Swedish population-based registries, we investigated the incidence of infections in 8,672 Swedish symptomatic MM patients diagnose
Soil management is a crucial aspect of sustainable agriculture, and traditional knowledge has played a pivotal role in shaping practices that maintain soil health over time. This study examines the significance of traditional soil management techniques used in Uttar Pradesh, India, and assesses their effectiveness in addressing modern agricultural challenges. The primary objective of this analysis
