Wear behavior of different coated tools in MQL-assisted milling of magnesium-based rare-earth alloys

open access: yesJournal of Materials Research and Technology, 2023
One of the most important and often employed indicators for describing machinability and machining quality is tool wear. While flank wear is commonly used to gauge the extent of a worn scar, tool wear is characterized more by its shape than its size.

Effect of Cutting Parameters on Tool Chipping Mechanism and Tool Wear Multi-Patterns in Face Milling Inconel 718

open access: yesLubricants, 2022
Tool wear behavior is mainly influenced by cutting parameters for a given tool–workpiece pair and cutting process. Rapid tool wear increases production costs and deteriorates machining quality in manufacturing industries.

Actionable Wearables Data for the Neurology Clinic: A Proof‐of‐Concept Tool

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Wearable devices can monitor key health and fitness domains. In multiple sclerosis (MS), monitoring step count and sleep is feasible, valid, and offers a holistic glimpse of patient functioning and worsening. However, data generated from wearables are typically unavailable at the point of care.

Active Seizures Predict Worse Instrumental Activities of Daily Living in Individuals With Normal Cognition and Dementia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Cognitive disorders are common in older persons with seizures (PWS). Cognitive disorders are often associated with impaired Instrumental Activities of Daily Living (IADLs). However, the effects of seizures on IADLs remain unexplored.

Ageism in Rheumatology: The Health Care Professional's Perspective

open access: yesArthritis Care &Research, EarlyView.
Objective Ageism (age‐based stereotypes, prejudice, or discrimination) is prevalent and linked to prolonged disability and reduced lifespan in older adults. Little is known about ageism within rheumatology. This study explores the health care professional's (HCP) perception of the care of older adults and how ageist attitudes or perspectives may impact
