Evaluation of the usefulness of post-contrast T2-FLAIR sequence MRI in the diagnosis of intracranial pathology

<title>Abstract</title> Background To demonstrate the diagnostic value of the CE-T2 FLAIR sequence in addition to CE-T1WI in MR imaging of intracranial pathologies. The CE-T2 FLAIR sequence is not widely utilised, but if included in standard MR acquisition protocols, it might enh...

“Acknowledge my grief” - experiences and needs of bereavement support in Sweden following the death of a loved one

<title>Abstract</title> Background Grief affects most people at some point, and is commonly associated with psychological distress, reduced well-being, and difficulties in everyday functioning. Support for the bereaved is crucial for grief management, but there is a lack of evide...

Finite-Basis Duality Estimate for the Surface-Code Threshold under Correlated Bit-Flip Errors

We apply finite-basis duality to a statistical-mechanical model introduced by Chubb and Flammia for the surface code under spatially correlated bit-flip noise, for which their mapping gives a random-bond Ising model with both two-body edge interactions and four-body face interact...

Poisson gauge theories in three dimensions: exact solutions and conservation laws

Abstract We investigate Maxwell–Chern–Simons theory on a three-dimensional noncommutative spacetime endowed with a constant Poisson structure. By exploiting the residual rotational symmetry, we construct exact classical solutions corresponding to pointlike electric and magnetic c...

Multi-pathogen situational assessment and forecasting of respiratory disease in Aotearoa New Zealand

Abstract Real-time analysis of epidemic trends and forecasts can help support public health planning and the response to seasonal respiratory disease. Here, we present two models that were used in a 2025 New Zealand winter situational assessment programme for three respiratory pa...

Microvascular remodeling and endothelial dysfunction across the post-COVID-19 spectrum: a prospective observational case-control study

<title>Abstract</title> Background Post-viral diseases, including post-COVID-19 syndrome (PCS) and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), cause substantial long-term morbidity. Persistent cardiovascular risk after acute infection highlights the need for acce...

Permeation Mechanisms of Calcium and Phosphate Ions into the Collagen Fibril Hole Zone

Abstract Collagen fibrils provide a templating scaffold for calcium phosphate deposition during bone mineralization, yet the molecular mechanism underlying the penetration of calcium and phosphate ions from the bulk phase into the collagen fibrils remains poorly understood. For t...

Joint economic and epidemiological modelling of alternative pandemic response strategies

Abstract In an emerging pandemic, policymakers need to make decisions with limited information and require trade-offs between the health impact of the pandemic and the economic costs of the response. Most mathematical models have focused on direct health impacts, neglecting the e...

Angular momentum in the teleparallel equivalent of general relativity

Abstract In teleparallelism, one is able to tackle the gravitational energy and angular momentum problems in a way that distinguishes this theory from other theories of gravity, such as general relativity. However, unlike the 4-momentum, the quantity that is usually identified wi...

Ingroup bias is prevalent in user reports of hate and abuse online

Abstract The prevalence of online hate and abuse is a pressing global problem. While tackling such societal harms is a priority for research across the social sciences, it is a difficult task, in part, because of the magnitude of the problem. People's engagement with reporting me...

The Fokas method for linear convection–diffusion equation with time-dependent coefficients and its extension to other evolution equations

Abstract In this paper, we study a linear convection–diffusion equation with time-dependent coefficients on a bounded interval, motivated by associated physical problems. We apply and adapt the unified transform method (UTM), also known as the Fokas method, which handles both tim...

Evaluating mental health and psychosocial support outcomes of the Self-Efficacy and Knowledge (SEEK) community-based randomized controlled trial in lebanon during active conflict

<title>Abstract</title> <bold>Background:</bold> Adolescent girls and young women (AGYW) affected by forced displacement are at high risk of poorer mental health and psychosocial wellbeing due to intersecting stressors. In humanitarian contexts like Lebanon, mental health challen...

CS-SHRED: enhancing SHRED for robust recovery of spatiotemporal dynamics

Abstract We present CS-SHRED, a novel deep learning architecture that integrates compressed sensing (CS) into a shallow recurrent decoder (SHRED) to reconstruct spatiotemporal dynamics from incomplete, compressed or corrupted data. Our approach introduces two key innovations. Fir...

A Born structure on the tangent bundle of a Hessian manifold

Abstract The Hessian structure is a geometric structure consisting of a pair $$(\nabla ,g)$$ ( ∇ , g ) of an affine connection $$\nabla $$ ∇ and a Riemannian metric g satisfying certain compatibility conditions. In information geometry, it is also known as a dually flat structure...

Tunable magnon polaritons via Eddy-current-induced dissipation in metallic-banded YIG spheres

Abstract We demonstrate a robust method to dynamically tune magnon dissipation in yttrium iron garnet spheres by equipping a metallic band around the sphere’s equator, enabling precise control over magnon-photon coupling states. The collective magnetization dynamics in the YIG sp...

Social and economic consequences of prestige and dominance in rural Colombian social networks

Abstract Social status regulates influence and well-being in most social animals. In humans, social status can be attained via distinct routes: prestige (tracking the ability of individuals to confer benefits) and dominance (tracking the ability of individuals to inflict costs)....

Obesity and sarcopenia affect the metabolite profiles of pet dogs

ABSTRACT Overweight and reduced muscle mass significantly affect canine health, yet their metabolic implications in dogs require further investigation. This study aimed to characterize metabolic alterations associated with overweight, obesity, and reduced muscle mass in dogs. An...

The essential regularity of singular connections in geometry

Abstract This paper, a culmination of the authors’ theory of the Regularity Transformation (RT-)equations, accomplishes the following: (i) We discover there is a true (geometric) regularity associated with every affine connection, its essential regularity, the highest possible re...
