Hypotensive Episodes Precede Cognitive Fluctuations in Parkinson's Disease Dementia

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Cognitive fluctuations (CFs) are a disabling feature in Parkinson's disease dementia (PDD) and contribute to caregiver burden. The relationship between CFs and neurogenic orthostatic hypotension (nOH), a common autonomic complication in PDD, has not been adequately examined.

Evolution of nanocrystalline “glaze” layers and subsurface ultrafine grain layers in high-temperature sliding wear

open access: yesFriction
The transition from severe to mild wear is an interesting phenomenon that is usually attributed to the nanocrystalline “glaze” layer and subsurface ultrafine grain layer. However, the formation of “glaze” layers and subsurface layers and their effects on
