Evaluating Large Language Models for Real World Vulnerability Repair in C/C++ Code

June 19, 2024
Author(s)
Lan Zhang, Qingtian Zou, Anoop Singhal, Xiaoyan Sun, Peng Liu
The advent of Large Language Models (LLMs) has enabled advancement in automated code generation, translation, and summarization. Despite their promise, evaluating the use of LLMs in repairing real-world code vulnerabilities remains underexplored. In this

Predicting the toughness of compatibilized polymer blends

June 19, 2024
Author(s)
Robert Ivancic, Debra Audus
Polymer blends can yield superior materials by merging the unique properties of their components. However, these mixtures often phase separate, leading to brittleness. While compatibilizers can toughen these blends, their vast design space makes

Analysis of Neural Network Detectors for Network Attacks

June 17, 2024
Author(s)
Qingtian Zou, Lan Zhang, Anoop Singhal, Xiaoyan Sun, Peng Liu
While network attacks play a critical role in many advanced persistent threat (APT) campaigns, an arms race exists between the network defenders and the adversary: to make APT campaigns stealthy, the adversary is strongly motivated to evade the detection

Assessing girth weld quality of pipeline steels and their susceptibility to hydrogen embrittlement

June 16, 2024
Author(s)
Zack Buck, Newell Moser, May Ling Martin, Nicholas Derimow, Damian Lauria, Enrico Lucon, Douglas Stalheim, Peter Bradley, Matthew Connolly
Hydrogen is known to cause premature failure in various steel infrastructures due to effects of embrittlement, which is particularly detrimental to ferritic steel structures such as pipelines and pressure vessels. Therefore, understanding the
