Air: Improving Agent Safety Through Incident Response, Zibo Xiao, Jun Sun, Junjie Chen

Research Collection School Of Computing and Information Systems

Large Language Model (LLM) agents are increasingly deployed in practice across a wide range of autonomous applications. Yet current safety mechanisms for LLM agents focus almost exclusively on preventing failures in advance, providing limited capabilities for responding to, containing, or recovering from incidents after they inevitably arise. In this work, we introduce AIR, the first incident response framework for LLM agent systems. AIR defines a domain-specific language for managing the incident response lifecycle autonomously in LLM agent systems, and integrates it into the agent's execution loop to (1) detect incidents via semantic checks grounded in the current environment state and …

Evaluating Variety- And Market-Class-Specific Effects Of Dietary Pulses On Human Health, Jiayu Tang

Department of Food Science and Technology: Dissertations, Theses, and Student Research

While pulses are globally recognized for their high levels of dietary fibers, protein, and polyphenols, research often focuses on characterizing the physiological effects of a single variety. This approach overlooks the substantial genetic and compositional diversity that exists across pulse varieties and individual market classes, which can differ extensively in nutrient content and structure. These compositional differences have the potential to produce distinct physiological and microbial responses in humans, yet variety- and market-class-specific effects remain poorly characterized.

This thesis uses two complementary research methodologies to investigate the health-relevant effects of different pulse varieties and market classes, providing foundational knowledge to …
