How materials behaviour affects power electronics reliability [PDF]
, 2022 S.74-79Life-time of power electronics assemblies is limited, mainly due to the numerous thermal cycles experienced in the mission profile. Differences in thermal expansion coefficients (CTE) of materials cause fatigue degradation, both in active power ...

Arthritis Care &Research, EarlyView.Objective We aimed to construct and evaluate the first laboratory‐based frailty index (FI‐Lab) for predicting adverse outcomes in systemic lupus erythematosus (SLE) and to compare its predictive ability to that of an existing clinical FI. Methods We used data from a single‐center prospective cohort of adult patients with SLE whose baseline visit ...

Arthritis Care &Research, EarlyView.Objective To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient‐reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient‐reported physical function differ according to four body composition profiles: high body fat, low lean mass ...
