Clinical and Imaging Characteristics of Parkinson's Disease with Negative Alpha‐Synuclein Seed Amplification Assay

open access: yesMovement Disorders, EarlyView.
Abstract Background The cerebrospinal fluid alpha‐synuclein seed amplification assay (CSFasynSAA) detects alpha‐synuclein aggregation in over 90% of individuals with sporadic PD (sPD). However, the clinical characteristics of sPD with negative CSFasynSAA remain undefined.

High Relative Accuracy Computations With Covariance Matrices of Order Statistics

open access: yesMathematical 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,

Post Activation Potentiation Is Greater in Human Triceps Brachii Versus Triceps Surae Muscles

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Voluntary muscle contractions result in a temporary increase in twitch force, a phenomenon termed post activation potentiation (PAP). In rodents and other species, PAP is observed predominantly or exclusively in fast twitch muscles. However, it has been suggested that in humans, PAP occurs more or less independently of muscle
