Tuning Interactions in Correlated Electron Systems: From Two-Band Superconductivity to Quasi-1D Spin Chains

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

A calcium sulphate/hydroxyapatite ceramic biomaterial carrier for local delivery of tobramycin in bone infections : Analysis of rheology, drug release and antimicrobial efficacy

Local targeted treatment of bone and joint infections using antibiotic-containing carriers is a common practice today. A recently FDA approved biphasic calcium sulphate/hydroxyapatite (CaS/HA) carrier containing gentamicin has been reported to give a sustained drug release, highly effective in eradicating bone infections. We present the first study evaluating the widely used aminoglycoside tobramy

X-ray Phase Contrast Tomography : Setup and Scintillator Development

X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale. To improve

The IPDGC/GP2 Hackathon - an open science event for training in data science, genomics, and collaboration using Parkinson’s disease data

Open science and collaboration are necessary to facilitate the advancement of Parkinson’s disease (PD) research. Hackathons are collaborative events that bring together people with different skill sets and backgrounds to generate resources and creative solutions to problems. These events can be used as training and networking opportunities, thus we coordinated a virtual 3-day hackathon event, duri

Advantages of binary stochastic synapses for hardware spiking neural networks with realistic memristors

Hardware implementing spiking neural networks (SNNs) has the potential to provide transformative gains in energy efficiency and throughput for energy-restricted machine-learning tasks. This is enabled by large arrays of memristive synapse devices that can be realized by various emerging memory technologies. But in practice, the performance of such hardware is limited by non-ideal features of the m

Understanding passive film degradation and its effect on hydrogen embrittlement of super duplex stainless steel – Synchrotron X-ray and electrochemical measurements combined with CalPhaD and ab-initio computational studies

The passive film stability on stainless steel can be affected by hydrogen absorption and lead to microstructure embrittlement. This work shows that the absorption of hydrogen results in surface degradation due to oxide reduction and ionic defect generation within the passive film, which decomposes and eventually vanishes. The passive film provides a barrier to entering hydrogen, but when hydrogen

Long-term exposure to traffic noise and risk of incident colon cancer : A pooled study of eleven Nordic cohorts

Background Colon cancer incidence is rising globally, and factors pertaining to urbanization have been proposed involved in this development. Traffic noise may increase colon cancer risk by causing sleep disturbance and stress, thereby inducing known colon cancer risk-factors, e.g. obesity, diabetes, physical inactivity, and alcohol consumption, but few studies have examined this. Objectives The o

Use of Virtual Reality in Psychiatric Diagnostic Assessments : A Systematic Review

BACKGROUND: Technological developments such as Virtual reality (VR) provide new opportunities to extend and innovate mental healthcare. VR as a tool for clinical assessment has been described as promising, as it can enable real-time assessment within real-like environments or contexts as opposed to self-report and behavioral tasks in laboratory settings.OBJECTIVE: With this systematic review we ai

Epigenetics of methylmercury

Purpose of review: Methylmercury (MeHg) is neurotoxic at high levels and particularly affects the developing brain. One proposed mechanism of MeHg neurotoxicity is alteration of the epigenetic programming. In this review, we summarise the experimental and epidemiological literature on MeHg-associated epigenetic changes. Recent findings: Experimental and epidemiological studies have identified chan

A stochastic hierarchical model for low grade glioma evolution

A stochastic hierarchical model for the evolution of low grade gliomas is proposed. Starting with the description of cell motion using a piecewise diffusion Markov process (PDifMP) at the cellular level, we derive an equation for the density of the transition probability of this Markov process based on the generalised Fokker–Planck equation. Then, a macroscopic model is derived via parabolic limit

The effects of sociodemographic factors and comorbidities on sepsis: A nationwide Swedish cohort study

Sepsis is a severe condition, representing a significant public health concern, especially in the elderly. There is, however, little insight into the potential effects of sociodemographic factors and comorbidities on sepsis incidence and how these factors interact. This was a nationwide open cohort study including individuals (N = 6746010) in Sweden ≥ 18 years of age spanning from 1997 to 2018, wi

Conversion efficiency of flight power is low, but increases with flight speed in the migratory bat Pipistrellus nathusii

The efficiency with which flying animals convert metabolic power to mechanical power dictates an individual's flight behaviour and energy requirements. Despite the significance of this parameter, we lack empirical data on conversion efficiency for most species as in vivo measurements are notoriously difficult to obtain. Furthermore, conversion efficiency is often assumed to be constant across flig

Forensic psychiatric patients’ experiences of participating in administrative court proceedings concerning the continuation of forensic psychiatric care

Introduction: Previous studies show that both staff and patients describe patient participation as a challenge in forensic psychiatry. One reason may be that the forensic psychiatric process is difficult to understand and is experienced as being slow and complex. The proceedings in an administrative court are a core element in forensic psychiatric care as it constitutes the legal authority that le

The governmentalisation of risk in liberal democracies : Four processes both making and breaking the governing of risk on the societal level

Numerous risks threaten modern society. Some are new, while others have existed since the beginning of time, but none have been governed on a societal level since their inception. Despite the abundance of literature addressing the governance of various risks, the processes by which they become governable in the first place have gotten little attention. As a result, this paper aims to improve our k

Towards realistic numerical modelling of thin strut-based 3D-printed structures

The as-built geometry and material properties of parts manufactured using Additive Manufacturing (AM) can differ significantly from the as-designed model and base material properties. These differences can be more pronounced in thin strut-like features (e.g., in a lattice structure), making it essential to incorporate them when designing for AM and predicting their structural behaviour. Therefore,
