"Vision-based object detectors can enhance the safety of autonomous navigation systems by perceiving the
surrounding environment, but they could be susceptible to adversarial attacks generated by artificial
intelligence (AI). In this work, we developed novel detection and defense mechanisms against adversarial
perturbations in vision-based perception for autonomous robotic systems. Particularly, we proposed
approaches to defend against visible and invisible white-box image perturbations in robot navigation
scenarios." Read more

"Mucosal healing is strongly linked to improved clinical outcomes in patients with inflammatory bowel disease; however, the specific role of the epithelium in driving this process in vivo remains poorly defined. To address this, we examined mucosal repair in an acute dextran sulfate sodium–induced colitis model in which epithelial-specific deletion of Smad4 results in an attenuated colitis response. We find that enhanced epithelial wound healing alleviates the fibrotic response." Read more

"This research investigates computational complexity aspects of word problems in HNN extensions. The study builds upon Miller’s classical result demonstrating the existence of HNN extensions with decidable word problems but undecidable conjugacy problems." Read more
