Research on the Impact Analysis and Preventive Measures of Not-Allowed Zones in Urban Rail Transit

Peng Fu,Yuhao Shi
If the pantograph of an urban rail transit train stays at the insulating anchor joint for a long time, it will cause a prolonged discharge between the pantographs, which may burn or even break the contact wire and interrupt the power supply. In order to prevent similar faults from happening in the future and provide references for other urban rail transit operation and construction units, this paper analyzes the principle and hazards of the fault caused by the train stopping in the power supply ...

Cost-Optimized and Efficacy-Driven Analysis of Antidepressants in Major Depressive Disorder: A Machine Learning and Visualization Approach

Rocco de Filippis,Abdullah Al Foysal
The treatment of major depressive disorder (MDD) often involves antidepressants, yet non-response to initial therapies remains a significant clinical and economic burden. This research aims to evaluate the comparative efficacy and cost-efficiency of 13 commonly prescribed antidepressants, spanning four major drug classes: SSRIs, SNRIs, NaSSAs, and TCAs. By employing machine learning and simulated patient data, we model non-response rates over two years, highlighting each drug’s cumulative risk t...
