Objective. To compare the rate of occurrence of comorbidities, including severe infections, in a population-based cohort of patients with biopsy-proven giant cell arteritis (GCA) with a reference population in Southern Sweden. Methods. The study included a population-based cohort of biopsy-proven GCA cases diagnosed between 1998 and 2010 from the Skane region in Southern Sweden (population: 1.2 mi

Background: Summary statistics often hide individual patients' suffering, thereby impeding quality improvement efforts. Objectives: We aimed to show the experience of a population with health care toward the end of life while preserving the experience of the individual. Design: We developed a data display method called per-patient illness trajectory analysis. We tested it using a demonstration coh

Complex forms of quantum entanglement can arise in two qualitatively different ways: either between many qubits or between two particles with higher-than-qubit dimension. While both the many-qubit frontier and the high-dimension frontier are well established, state-of-the-art quantum technology is becoming increasingly able to create and manipulate entangled states that simultaneously feature many

Understanding the nature of the photoexcitation and ultrafast charge dynamics pathways in organic halide perovskite nanocubes and their aggregation into superlattices is key for potential applications as tunable light emitters, photon-harvesting materials, and light-amplification systems. In this work, we apply two-dimensional coherent electronic spectroscopy (2DES) to track in real time the forma

BACKGROUND: Parents experience a range of mental health disorders following their child's cancer diagnosis. It is thus essential to explore how the child's cancer diagnosis affects the dosage of psychotropic medication in both short- and long-term use, as well as potential disparities in utilization patterns between mothers and fathers.PATIENTS AND METHODS: Using Swedish registers, we identified a

In the field of sensing, the development of sensors with high sensitivity, accuracy, selectivity, sustainability, simplicity, and low cost remains a key focus. Over the past decades, optical and electrochemical sensors based on molecular imprinting techniques have garnered significant attention due to the above advantages. Molecular imprinting technology utilizes molecularly imprinted polymers (MI

We study tests of quantum steering in which the trusted party does not have perfect control of their measurements. We report on steering inequalities that remain unaffected when introducing up to a threshold magnitude of measurement imprecision. This phenomenon, which we call an imprecision plateau, thus permits a departure from the standard assumption of idealized measurements without incurring a

We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method for detecting the entanglement dimensionality through certification of the Schmidt number. Its key feature is that the computational cost is independent of the Schmidt number under consideration. Secondly, we provide a m

Background: Electroconvulsive therapy (ECT) is an effective treatment for depression with potential transient cognitive side effects. However, subjective memory impairment can extend over a long period after ECT. Objectives: This study aimed to assess potential risk factors for long-term subjective memory impairment 6 months after ECT and to explore if the associations are mediated by depressive s

Compacted graphite iron (CGI) is an intermediate material between conventional grey cast iron and the stronger, more wear resistant ductile iron, making it a suitable material choice for different automotive applications. The improved material properties of CGI as to conventional grey cast iron makes it more difficult to machine, and finding a suitable tool material with low wear rates is a challe

Superlattices of quantum-confined perovskite nanocrystals (5–6 nm) present an interesting example of colloidal crystals because of the interplay between nanoscopic parameters (nanocrystal sizes, shapes, and colloidal softness) and the microscopic shapes of their assemblies. These superlattices are reported as rectangular or rhombic, with little discussion of the outcomes of self-assembly experimen

Transition metal complexes (TMCs) with charge transfer states play a crucial role in photophysical and photochemical processes, particularly in energy conversion applications. This thesis investigates the photophysics and photochemistry of the d⁵ ruthenium complex ([Ru(III)(phtmeimb)2]+), focusing on its excited-state dynamics and charge transfer properties. The photophysical study involves steady

This paper introduces an innovative framework that enhances digital twins with deep reinforcement learning (DRL) to support maintenance in manufacturing systems. Utilizing a sophisticated artificial intelligence (AI) layer, this framework integrates real-time and historical production data from a physical manufacturing system to a digital twin, enabling dynamic simulation and analysis. Maintenance

BACKGROUND: Preeclampsia is a hypertensive pregnancy disorder marked by endothelial damage. Healthy endothelium is covered by a protective glycocalyx layer, which, when degraded, releases detectable products into the blood. Sphingosine-1phosphate (S1P) is a cardiovascular biomarker involved in glycocalyx preservation, linked to placentation and preeclampsia development. The study aimed to test the

Background: Perfluorinated alkyl substances (PFAS) are suggested to impair immune function in children. Previous studies investigating associations between prenatal PFAS exposure and common infections were performed in background-exposed populations whilst studies from high-exposed populations are lacking. Objectives: To investigate the association between prenatal PFAS exposure from contaminated

Introduction: Persistent pharmaceutical contaminants, such as Platinum cytostatics, commonly used in cancer therapy, have been detected in water bodies at low concentrations. Electrochemical, photochemical and biological treatments for the removal and degradation of these contaminants are expensive and sometimes ineffective. Sorption methods are a viable and more efficient alternative. Objectives:
