Background: Helicobacter pylori (Hp) and its virulence factor Cytotoxin-associated gene A (CagA) have been linked to myocardial infarction (MI), but the mechanisms are unknown. This study aims to test if Hp infection and CagA are associated with pre-specified inflammatory and vascular biomarkers in patients with MI and to explore whether a broader biomarker panel can predict infection. Furthermore

This study investigated the retention of spatial knowledge in buildings following route-learning training in a virtual reality environment. A total of 121 participants were tested up to three months later on putting waypoints of the route in the correct order and recalling directions at waypoints. Memory accuracy declined over time, consistent with classic memory theory. Route knowledge was retain

We present the design and implementation of a portable transfer system equipped with an integrated electrochemical cell that enables the controlled transfer of samples between an electrochemical environment and an ultrahigh vacuum (UHV) system without air exposure. This setup allows for the preparation of well-defined model surfaces, their electrochemical modification, and subsequent structural an

This study presents high-fidelity Large Eddy Simulations (LES) of supersonic combustion in a Mach 2 cavity flameholder over the full stable fueling region from 40 to 200 slpm. The simulations employ Finite Rate Chemistry LES with the Z70 ethylene-air mechanism, the Localized Dynamic k-equation model, Partially Stirred Reactor turbulence-chemistry interaction model, conjugate heat transfer, and the

The shape of reef-building corals largely determines how they interact with their environment and the ecosystem services they provide. However, morphology is not fixed. As corals grow and develop from singular polyps to mature adult colonies, they experience pronounced changes in their morphology. This developmental trait variation remains poorly quantified in corals, despite their importance as e

The sheet metal forming process is integral to the automotive industry, producing a variety of components essential for vehicle construction, including body panels, chassis parts, and structural supports. The process involves shaping thin metal sheets into desired forms using techniques such as bending, stretching, drawing, and stamping. In order to build high quality cars it is vital with an effi

Background All hospital laboratories in Sweden use the Owren prothrombin time (PT) method primarily to monitor anticoagulant treatment. Direct international normalized ratio (INR) calibration was introduced in 1999 under the supervision of Equalis, the national organization for external quality assessment (EQA) in laboratory medicine. Objectives We present 25 years of combined experience in develo

Based on data on AI capabilities and occupational work content, we develop and validate a time-variant measure for occupational exposure to AI across subdomains of AI, such as language moWe unbox developments in artificial intelligence (AI) to estimate how exposure to these developments affect firm-level labour demand, using detailed register data from Denmark, Portugal and Sweden over two decades.

Case study research plays an important role for social and political scientists working within the qualitative tradition, with the field of international relations (IR) being no exception. This article provides methodological reflections on the challenges of investigating ‘elusive’ cases within the global governance domain of IR. Taking stock of my experience of studying global multi-stakeholder p

Objective Transcriptomic subtyping is not yet standardized for prognostic use in epithelial ovarian cancer (EOC). This study aims to validate RNA sequencing (RNAseq) from formalin-fixed, paraffin-embedded (FFPE) tissues and to evaluate survival-associated transcriptomic subtypes and differentially expressed genes (DEGs) in a clinical trial cohort. Methods An exploratory post hoc analysis was condu

INTRODUCTION: Resection of intraductal papillary mucinous neoplasm (IPMN) aims to prevent progression to invasive pancreatic cancer. However, the risks of pancreatic surgery and frequent findings of low-grade dysplasia (LGD) raise concerns about overtreatment. This EAHPBA-endorsed multinational study evaluated short- and long-term overall survival (OS) following preventive resection for IPMN (with

Climate change is recognized as one of the greatest environmental threats facing the world today. To tackle this problem, a protocol was adopted in Kyoto in 1997 which establishes legally binding commitments to developed countries to bring down the emissions of six major greenhouse gases by 5.2% compared to the year 1990. Three flexibility mechanisms have been provided to developed countries to ac

Women constitute a minority among patients in forensic psychiatric care, which aims to improve the patients’ health while ensuring safety for patients, caregivers, and society. Participation in forensic psychiatric care can be complex; its definition depends on the context and perspective and is influenced by several factors. This study examined the perceptions of female patients and caregivers re

During periods of economic and social stability, retailers rarely need to address grocery hoarding. However, in times of crises, understanding the driving mechanisms behind hoarding becomes crucial. This study investigates the relationship between consumers’ personality traits and grocery hoarding in Sweden during the beginning of Covid-19, applying the Five-Factor Model of personality (FFM), whic

This paper presents a two-phase heuristic methodology aimed at the reconfiguration of a radial distribution network with the objective of minimizing the computational time. In the preliminary phase of the operation, all network switches are in a closed state, and it is proposed that a subsequent switch opening methodology be employed to achieve a configuration that approximates optimal radial char

We present iHOMER, an iterative version of the HOMER method to extract Lund fragmentation functions from experimental data. Through iterations, we address the information gap between latent and observable phase spaces and systematically remove bias. To quantify uncertainties on the inferred weights, we use a combination of Bayesian neural networks and uncertainty-aware regression. We find that the

The European land carbon uptake has been heavily impacted by several recent severe droughts, yet quantitative estimates of carbon uptake anomalies are uncertain. Atmospheric CO2 inverse models (AIMs) provide observation-based estimates of the large-scale carbon flux dynamics, but how well they capture drought impacts on the terrestrial carbon uptake is poorly known. Here we assessed the capacity o
