Adversarial Text Purification: Large Language Model Approach for Defense
Background Adversarial purification is a defense mechanism for safe-guarding classifiers against adversarial attacks without knowing the type of attacks or training of the classifier. These techniques analyze and eliminate adversarial perturbations from the attacked inputs, and help to restore purified samples that retain similarity to the attacked...

Compact X-Ray Light Source Design
Background X-ray free-electron lasers (XFELs) produce x-ray pulses with durations shorter than 100 femtoseconds. Each pulse contains enough photons to produce a diffraction pattern from a nanocrystal in a single shot, while avoiding most effects of radiation damage. XFELs are increasing in prevalence in a range of applications due to their capacity...
