Movement Disorders, EarlyView.Abstract Background Parkinson's disease is mainly characterized by dopaminergic neurodegeneration in the substantia nigra pars compacta (SNc) and α‐synuclein accumulation. The locus coeruleus (LC) is also affected in Parkinson's disease and linked to some nonmotor symptoms, but the extent and timing of its degeneration remain unclear.

Movement Disorders, EarlyView.Abstract Background Neuroinflammation, measured using [11C](R)‐PK11195 positron emission tomography (PET), has been reported in isolated rapid‐eye‐movement sleep behavior disorder (iRBD), but its temporal progression is unknown. Objective The aim was to assess longitudinal progression of neuroinflammation in iRBD patients and its relationship with ...

High Relative Accuracy Computations With Covariance Matrices of Order Statistics
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (
