Distinct resting-state effective connectivity of large-scale networks in first-episode and recurrent major depression disorder: evidence from the REST-meta-MDD consortium

IntroductionPrevious studies have shown disrupted effective connectivity in the large-scale brain networks of individuals with major depressive disorder (MDD).However, it is unclear whether these changes differ between first-episode drug-naive MDD (FEDN-MDD) and recurrent MDD (R-MDD).MethodsThis study utilized resting-state fMRI data from 17 sites

Structural response of an injection molding part of the fuser mechanism in laser printer under thermo-mechanical coupling

Laser printer internal parts are prone to deformation when they are working in high temperature environment for a long time, resulting in machine faults such as paper jam and angle folding.In order to predict the deformation of parts in thermal environment and further determine their initial allowable deformation, so as to guide the structural desi
