The $q$-Onsager algebra $O_q$ has a presentation involving two generators $W_0$, $W_1$ and relations, called the $q$-Dolan/Grady relations. alternating central extension $\mathcal O_q$ $\lbrace \mathcal W_{-k}\rbrace_{k=0}^\infty$, W_{k+1}\rbrace_{k=0}^\infty$, $ \lbrace G_{k+1}\rbrace_{k=0}^\infty$, {\tilde G}_{k+1}\rbrace_{k=0}^\infty$ large number of Let $\langle W_0, W_1 \rangle$ denote sub...

grammaticalization provides a framework to study the genesis and development of grammatical forms in language. in this framework, it is argued that new grammatical forms are constantly developed from lexical items and the already formed grammatical items may go out of use. in spite of some counterexamples, this is often seen as a unidirectional and cyclic process. in this article the concepts o...

BACKGROUND The clinimetric properties of knee goniometry are essential to appreciate in light of its extensive use in the orthopaedic and rehabilitative communities. Intra-observer reliability is thought to be satisfactory, but the validity and inter-rater reliability of knee goniometry often demonstrate unacceptable levels of variation. This study tests the validity and reliability of measurin...
