PdAg nanoparticles with a diameter of 10 nm have been generated by an aerosol particle method, and supported on a silica substrate. By using a combination of X-ray Energy Dispersive Spectroscopy and X-ray Photoelectron Spectroscopy it is shown that the size distribution of the particles is narrow and that the two metals form an alloy with a mixture of 75% Pd and 25% Ag. Under oxidizing conditions,
Alcohol consumption contributes to many negative health consequences and is a risk factor for death. Some previous studies however suggest a J-shaped relationship between the level of alcohol consumption and all-cause mortality. These findings have in part been suggested to be due to confounders. The aim of our study was to analyze the relationship between self-reported alcohol intake and all-caus
Background: Aortic valve calcification (AVC) is an underlying pathophysiological mechanism in aortic stenosis, which shares many risk factors with diabetes. However, the association between dysglycemia and early stages of AVC remains unclear. The aim was to examine the associations between stages of dysglycemia and signs of AVC among middle-aged individuals from the general population. Methods: Th
Purpose: The purpose of this case-control study was to investigate the associations between maternal serum concentrations of vitamin D early in pregnancy and the occurrence of preterm birth. Methods: The study included 269 women (cases) whose children were born preterm (< 37 gestational weeks [gw]) and 332 women (controls) whose children were born term (≥ 37 gw). Among the cases, 59 were extreme p
Purpose:The purpose is to identify factors influencing the environmental sustainability of e-commerce packaging across its lifecycle.Design/methodology/approach:A systematic literature review captured 45 articles. To categorise the literature, a conceptual framework based on a lifecycle perspective was developed. An actor perspective analysed their influence and responsibilities.Findings:Five fact
ABSTRACT Child undernutrition remains a significant public health issue in Bangladesh, with high rates of stunting, wasting, and underweight. The Composite Index of Anthropometric Failure (CIAF) offers a comprehensive tool for assessing overall undernutrition. Although previous studies in Bangladesh have utilized CIAF, they have relied on older datasets. Estimating the current status is essential
Modern test theory supplements the more prevalent classic methods for assessing test properties. However, such an assessment of the commonly used sexual recidivism risk assessment instrument, Static-99R, has yet to be attempted. This study evaluated the psychometric properties of said instrument using Rasch analysis. The clinical cohort assessed consisted of individuals with mental disorders convi
BACKGROUND: Discrimination may further impede access to medical care for individuals in socially disadvantaged positions. Sociodemographic information and perceived discrimination intersect and define multiple contexts or strata that condition the risk of refraining from seeking physician's care. By applying analysis of individual heterogeneity and discriminatory accuracy (AIHDA) we aimed to impro
Background: The mechanisms underlying alcohol-induced breast carcinogenesis are not fully understood but may involve hormonal changes. Methods: Cross-sectional associations were investigated between self-reported alcohol intake and serum or plasma concentrations of estradiol, estrone, progesterone (in premenopausal women only), testosterone, androstenedione, dehydroepiandrosterone sulfate, and sex
Background: Reliable and valid assessment of paranoia is important in forensic psychiatry for providing adequate care. VR technology may add to current assessment procedures, as it enables observation within realistic (social) situations resembling the complexity of everyday life. VR constitutes a promising tool within forensics, due to the restricted nature of forensic psychiatric hospitals and e
Aims: Economic simulation models, such as the IHE Type 2 Diabetes Cohort Model (IHE-DCM-T2), are used widely to inform resource allocation for Type 2 Diabetes (T2D) treatments. Recently, IHE-DCM-T2 was augmented with Japanese-specific risk equations to align with the Japanese healthcare context. This study extends prior model validation of IHE-DCM-T2 to cover the Japanese risk equations for applic
Objective: To identify predictors of GCA in patients with PMR. Methods: Patients with PMR were identified among participants in two population-based health surveys. Those with a registered diagnosis indicating PMR in national and regional registers (the latter including primary care) were included. Medical records from hospitals and primary care were systematically reviewed. PMR diagnoses were ver

Convergence analysis of a full discretization of operator-valued differential Riccati equations Eskil Hansen Tony Stillfjord Teodor Åberg April 28, 2026 Abstract In recent previous work [E. Hansen, T. Stillfjord and T. Åberg, SIAM J. Numer. Anal., to appear], we analyzed the convergence of operator splitting methods applied to operator-valued differential Riccati equations (DRE).

Vegetation fire is one of the naturally occurring disturbances within the Earth system, changing vegetation dynamics and modulating carbon storage in the terrestrial biosphere. While fires are essential to many ecosystems, fire dynamics have been increasingly shaped by human actions since the late eighteenth century. The main drivers behind those changes are climate change and direct human activit
