Optimal Placement and Sizing of Series and Shunt Compensation for Improving Power Systems Operation
International Journal of Energy Research, Volume 2026, Issue 1, 2026.Power systems are complex, and power demand has constantly increased over time. Moreover, power transmission systems have a limited capacity, causing the increase in demand to be difficult to accommodate. Additional system requirements include maintaining voltages within specific values and limiting voltage drop in the lines to ensure voltage stability,

Regional cortical network atrophy predicts progression to dementia in the Lewy body diseases
Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.Abstract INTRODUCTION The timeline from symptom onset to the loss of independent functioning varies across patients with Lewy body disease (LBD). Here, we investigate whether the magnitude of cortical atrophy within functional networks that subserve cognitive and affective functions has utility in predicting progression to dementia in LBD.
