On permutable \(n\)-groups

open access: yes, 1988
An \(n\)-groupoid \((G,f)\) is called \(i\)-permutable iff \(f(x_ 1,...,x_{i- 1},f(x_ 1,...,x_ n),x_ i,...,x_{n-1})=x_ n\), for all \(x_ 1,x_ 2,...,x_ n\in G\) and fixed \(i\in\{1,2,...,n\}\). The authors prove that every such \(n\)-group is \(c\)-derived from a Boolean group.

Higher Amyloid and Tau Burden Is Associated With Faster Decline on a Digital Cognitive Test

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective A 2‐min digital clock‐drawing test (DCTclock) captures more granular features of the clock‐drawing process than the pencil‐and‐paper clock‐drawing test, revealing more subtle deficits at the preclinical stage of Alzheimer's disease (AD). A previous cross‐sectional study demonstrated that worse DCTclock performance was associated with
