Associations of Rheumatoid Arthritis Disease Activity with Frailty Over Five Years of Follow‐up
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)

DEVELOPMENT OF CYCLIC SLIP BANDS IN UFG COPPER IN GIGACYCLE FATIGUE
Ultrafine-grained (UFG) copper studied in this paper was produced by equal channel angular pressing (ECAP) method and tested in gigacycle fatigue region. In contrary to conventional grain size copper, the appearance of cyclic slip bands is quite rare and
