  2. Background Modern electrical grids tend to have higher penetration of intermittent energy sources. The grid infrastructure is also more susceptible to physical damage due to increased extreme weather events. Grid operators have to run multiple power flows for different scenarios in real time to continuously monitor the system states and make necessary...

  3. Background Airborne dust emission can lead to adverse effects on human health (e.g., respiratory problems and cardiovascular issues) and the surrounding environment (e.g., contamination of water bodies and degradation of vegetation). One commonly used short-term method to mitigate airborne dust is spraying water on the soil surface. However, as the...

  6. Background Text classification models have become increasingly prevalent in cybersecurity applications, but remain susceptible to adversarial examples (e.g., carefully crafted sentences with human-unrecognizable changes to the inputs, that are misclassified). Adversarial attacks provide profound insights into the classifiers’ vulnerabilities,...
