Associations of Rheumatoid Arthritis Disease Activity with Frailty Over Five Years of Follow‐up
Arthritis Care &Research, Accepted Article.Objective To evaluate whether rheumatoid arthritis (RA) disease activity is associated with frailty both in cross‐section and longitudinally. Methods Participants within the Veterans Affairs Rheumatoid Arthritis registry enrolled from 2003 to 2022 were included. The exposure was RA disease activity measured by Disease Activity Score in 28‐joints (DAS28)

The reduced order model problem in distributed parameter systems adaptive identification and control [PDF]
The basic assumption that a large space structure can be decoupled preceding the application of reduced order active control was considered and alternative solutions to the control of such structures (in contrast to the strict modal control) were ...

Arthritis Care &Research, Accepted Article.Objectives Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), yet the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to: 1) identify clinical factors that predict ...

Journal of King Saud University: Engineering Sciences, 2002 Tuning of PI control algorithms for coupled multi input multi output (MIMO) systems is a challenging problem. This paper extends a previously developed model-based adaptive tuning method to handle the tuning problem of coupled multivariable systems.
