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

Neutron scattering techniques have been employed to investigate two key areas of condensed matter physics: superconductivity and quantum magnetism. The experimental studies span two distinct areas: two-band superconductors, where we explore the interplay between superconducting anisotropy and vortex structure, and quasi-one-dimensional (quasi-1D) spin chains, where we investigate the magnetic exci

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

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

Imminent crises and the much-needed transition to a sustainable society bring knowledge about de-implementation to the fore. Using case studies with inspiration from process tracing, and with tools from Charles Tilly’s theory on Durable inequality, we identify mechanisms that generate inequality and counteract the implementation of recovery – and strength-based practices. Our case studies of socia

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

We present the building blocks of an energy-efficient on-chip platform for neural network applications based on III-V semiconductor nanowires and nanopillar arrays. These will work as emitting and detecting neurosynaptic nodes for spiking nanocircuits, as light sensors that emulate navigational properties of insect vision systems.

Precision laser frequency stabilization is an important part of modern optical metrology, with applications ranging from atomic clocks to fundamental tests of physics. However, the frequency stability of the ultrastable cavities used in these experiments is fundamentally limited by thermal noise in the mirrors of the cavity. The thermal noise causes the atoms that form the mirrors to move randomly

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:

Metal halide perovskites and related materials have sparked intense debate in the field of optoelectronic applications, including solar cells, light-emitting diodes, and lasers. Despite significant progress in improving device efficiency and stability, understanding the structure-property relationships remains largely elusive. This thesis presents an in-depth investigation of the structural dynami

The accumulation of amyloid fibrils from the protein 𝛼-synuclein is a pathological hallmark of Parkinson´s disease. 𝛼-synuclein is a highly polar protein with a remarkable primary structure that can be divided into three regions: the slightly basic N-terminal region, a central hydrophobic region, and a highly acidic C-terminal tail. The C-terminal tail is of specific focus in this thesis. A chan

The discovery of ferroelectricity in nanoscale hafnia-based oxide films has spurred interest in understanding their emergent properties. Investigation focuses on the size-dependent polarization behavior, which is sensitive to content and movement of oxygen vacancies. Though polarization switching and electrochemical reactions is shown to co-occur, their relationship remains unclear. This study emp

OBJECTIVE: Systemic inflammatory autoimmune diseases (SIADs) such as systemic lupus erythematosus (SLE), primary Sjögren disease (pSS), and idiopathic inflammatory myopathies (myositis) are complex conditions characterized by shared circulating autoantibodies and clinical manifestations, including skin rashes, among others. This study was aimed at elucidating the genetics underlying these common f

We harness the complex mixing process inside a commercial multi-mode fibre to program high-dimensional linear optical circuits for photonic qudits encoded in transverse space and time-of-arrival, and demonstrate their use for high-dimensional entanglement certification.
