Arthritis Care &Research, Accepted Article.Objectives Systemic lupus erythematosus (SLE) is a heterogenous inflammatory condition, with widely varying global prevalence estimates. Frequency of SLE in the general population of Australia has been reported to be notably lower than contemporary estimates in countries such as the US or UK at 19‐39 per 100,000 as opposed to 65‐97 per 100,000.

Assessment of power system security using Security Information Index
IET Generation, Transmission & Distribution, 2019 Power system security assessment is important for the analysis of a power system network. The security analysis is based on equality constraint of generation‐demand balance and inequality constraints of maximum voltage and current limits. The lack of a single measure to identify the state of the power system network limits the analysis of security and ...

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs
Advanced Engineering Materials, EarlyView.This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable
