The magnetic Laplacian on the disc for strong magnetic fields

The magnetic Laplacian on a planar domain under a strong constant magnetic field has eigenvalues close to the Landau levels. We study the case when the domain is a disc and the spectrum consists of branches of eigenvalues of one dimensional operators. Under Neumann boundary condition and strong magnetic field, we derive asymptotics of the eigenvalues with accurate estimates of exponentially small

Symptoms indicative of early knee osteoarthritis after ACL reconstruction : descriptive analysis of the SHIELD cohort

Objective: To describe the SHIELD cohort in terms of symptoms indicative of early knee osteoarthritis (OA) and to investigate associations between patient characteristics (demographics, activity/injury-related) and these symptoms at 1 (cross-sectional) and 3 years (longitudinal) post anterior cruciate ligament reconstruction (ACLR). Method: 106 participants (50 ​% women, mean [SD] age 25 [5] years

Muscle activity mapping by single peak localization from HDsEMG

Human-machine interfaces using electromyography (EMG) offer promising applications in control of prosthetic limbs, rehabilitation assessment, and assistive technologies. These applications rely on advanced algorithms that decode the activation patterns of muscles contractions. This paper presents a new approach to assess and decode muscle activity by localizing the origin of individual temporal pe

Prodomain processing controls BMP-10 bioactivity and targeting to fibrillin-1 in latent conformation

Bone morphogenetic protein 10 (BMP-10) is crucial for endothelial cell signaling via activin receptor-like kinase 1 (ALK1), a pathway central to vascular homeostasis and angiogenesis. Dysregulated BMP-10 signaling contributes to cardiovascular diseases and cancer, highlighting the need to control ALK1-mediated endothelial responses to BMP-10 for therapeutic development. BMP-10 biosynthesis involve

Diagnostic accuracy of the Scandinavian guidelines for minor and moderate head trauma in children : a prospective, pragmatic, validation study

Background: Current guidelines for initial management of traumatic brain injury (TBI) support decision making, but they are rarely validated. The Scandinavian guideline for management of children with TBI (SNC16) was developed to minimise the use of cranial computed tomography (cCT) without compromising safety, but the performance of the guideline in a real-world population is unknown. We aimed to

Nudging : An experiment on transparency, accounting for reactance and response time

Is being informed about a nudge detrimental to its effect? This paper reports results from an experimental online study testing the effects of transparency on the effectiveness of a default nudge while accounting for psychological reactance and response time. Overall and in line with earlier studies, we find no negative effect of transparency on average behaviour. Adding to the previous discussion

Experimental study on thermal runaway evolution and toxicity hazard of lithium-ion batteries in a tunnel under longitudinal air flow

The widespread adoption of lithium-ion batteries (LIBs) for energy storage has introduced significant fire risks, particularly in confined and restricted environments such as tunnels. This study investigated thermal runaway (TR) behavior in a model tunnel at ventilation speeds ranging from 0 m/s to 2.5 m/s, using LiFePO4 (LFP) and LiNixCoyMnzO2 (NCM) batteries. The experiments identified two criti

Adolescents’ personality and sex, age, socioeconomic status in explaining mental health : A representative Swedish national study

Objective: The present study compared individual personality traits and demographic variables, i.e. sex, age, and socioeconomic status, in explaining mental health in a large representative adolescent Swedish high school survey. Method: This data collection on 15- to 18-year-olds (N = 10,288, response rate 79 %) was conducted in 2024 and included, for the first time, a brief Big Five personality m

När ska en utlämnings förenlighet med Europakonventionen och barnkonventionen prövas? – analys

Beslut om utlämning fattas av regeringen efter yttrande från Riksåklagaren. Om den eftersökte inte samtycker till utlämning yttrar sig även Högsta domstolen (HD). I den här analysen behandlar JP Infonets expert Christoffer Wong, universitetslektor i straff- och straffprocessrätt, processen i utlämningsärenden. Han diskuterar särskilt frågan om och när HD:s prövning bör omfatta förenligheten med Eu

High-frequency/high-field electron paramagnetic resonance generalized spectroscopic ellipsometry characterization of Cr3+ in β-Ga2O3

Electron paramagnetic resonance of Cr3+ ions in β -Ga2O3 is investigated using terahertz spectroscopic ellipsometry under magnetic field sweeping, a technique that enables the polarization resolving capabilities of ellipsometry for magnetic resonance measurements. We employed a single-crystal chromium-doped β -Ga2O3 sample, grown by the Czochralski method, and performed ellipsometry measurements a

Magnetic Lyddane-Sachs-Teller Relation

We describe a magnetic relation in analogy to the well-known dielectric Lyddane-Sachs-Teller relation [R. H. Lyddane et al., Phys. Rev. 59, 673 (1941)PHRVAO0031-899X10.1103/PhysRev.59.673]. This magnetic relation follows directly from the model equations for nuclear induction due to fast oscillating electromagnetic fields [F. Bloch, Phys. Rev. 70, 460 (1946)PHRVAO0031-899X10.1103/PhysRev.70.460] a

Influence of autochthonous Lactiplantibacillus plantarum strains on microbial safety and bioactive compounds in a fermented quinoa-based beverage as a non-dairy alternative

Plant-based alternatives are considered microbiologically safe; however, recent studies have raised concerns about hygienic quality. Additionally, the relationship between microbiological safety and polyphenolic content in fermented products remains unexplored. This study assessed the potential of four autochthonous Lactiplantibacillus plantarum strains (3, 5, 9, and 10) to impact microbial com

Determining the effect of frailty on survival in advanced ovarian cancer: study protocol for a prospective multicentre national cohort study (FOLERO)

Background and purpose: There is an urgent need to improve patient-selection to surgical treatment in advanced ovarian cancer as our results showed that cytoreductive surgery was without effect or even detrimental in a yet unknown subgroup of women. With an ageing population, 30% of women with advanced ovarian cancer in Sweden are >75 years. Nevertheless, there are no recommendations on patient-se

Increased frontocortical microvascular raspberry density in frontotemporal lobar degeneration compared to Lewy body disease and control cases: a neuropathological study

Background: Brain raspberries are histologically defined microvascular entities that are highly prevalent in the neocortex. Increased cortical raspberry density occurs in vascular dementia, but also with advancing age. Here, we examined the raspberry density in two neurodegenerative diseases, wherein vascular alterations distinct from conventional vascular risk factors have been indicated: frontot

Visualization of unsteady combustion of single aluminum droplets: coalescence, eruption and fragmentation

Detailed characterization of the unsteady combustion behaviors of individual aluminum (Al) droplets is scarce, due to the experimental challenges in resolving the transient phenomena at the micrometer scale. In this work, we spatiotemporally elucidate the complex interplay, including droplet coalescence, eruption, and fragmentation, of individually burning Al droplets and alumina (Al2O3) products,

A CO2–Δ14CO2 inversion setup for estimating European fossil CO2 emissions

Independent estimation and verification of fossil CO2 emissions on a regional and national scale are crucial for evaluating the fossil CO2 emissions and reductions reported by countries as part of their nationally determined contributions (NDCs). Top-down methods, such as the assimilation of in situ and satellite observations of different tracers (e.g., CO2, CO, Δ14CO2, XCO2), have been increasing
