We study the periodicity of subshifts finite type (SFT) on Baumslag-Solitar groups. show that for residually groups there exist both strongly and weakly-but-not-strongly aperiodic SFTs. In particular, this shows unlike Z2, but like Z3, strong weak SFTs are different classes in BS More precisely, we prove a weakly SFT BS(m,n) due to Aubrun Kari is, fact, BS(1,n); not any other BS(m,n). addition,...

The Newton-Raphson (N-R) method is useful to find the roots of a polynomial degree n. However, this limited since it diverges for case in which polynomials only have complex if real initial condition taken. In present work, we explain an iterative that created using fractional calculus, will call Fractional (F N-R) Method, has ability enter space numbers given condition, allows us both and unli...

Background: Due to the obvious differences in the natural course of rheumatoid arthritis (RA) and osteoarthritis (OA),different functional outcomes might be expected after Total Knee Arthroplasty (TKA) in these distinct patients. Althoughseveral studies have reported the objective outcome of TKA in RA and OA patients, few studies have compared postoperativepatient-satisfaction levels.Methods: I...
