The presence and pattern of iron accumulation in subcortical vascular mild cognitive impairment (svMCI) and their effects on cognition have rarely been investigated. We aimed to examine brain iron deposition in svMCI subjects using quantitative susceptibility mapping (QSM). Moreover, we aimed to investigate the correlation between brain iron deposition and the severity of cognitive impairment a...

In response to relatively little evidence on the determinants of financial distress in cooperative institutions (e.g., Credit Unions), this paper proposes a indicator Merton Distance default (Merton DD), which was constructed with z-score, possessed improved predictive capability, but reducing equity volatility. This model possesses advantages both hazard and modified DD model, could timely ref...
