Calming the Chaos: AI-Powered Disaster Response
![Despite inherent model prediction errors [latex]RMSE=0.19[/latex] for Hurricane Harvey and [latex]0.29[/latex] for Irma, a learned actor-critic policy demonstrably reduced mean fear by approximately 70% in Harvey and 50% in Irma-despite a higher initial fear level in the latter-while simultaneously maintaining or improving power availability and physical health, suggesting effective intervention even when extrapolating to novel but related disaster scenarios.](https://arxiv.org/html/2604.08802v1/artifacts_irma/plots/states.png)
A new framework leverages artificial intelligence to coordinate critical resources during disasters, minimizing public fear and maximizing the effectiveness of emergency services.

Beyond the Crash: Building Resilient Investment Strategies
![The system distills market momentum by first identifying sector leaders based on cumulative growth [latex]R_{i}[/latex], then refining this selection via a Volatility-Adjusted Momentum (VAM) score to establish an ‘Anchor Triad’ - the top three most robustly trending sectors - thereby constructing a portfolio grounded in prevailing structural forces.](https://arxiv.org/html/2604.09060v1/signal_gen_module.png)
