Gao, Y. (author), Liu, X. (author), Ren, S. (author), Li, Yuanyuan (author), Zhang, Yuqing (author)Surface energy is a key material property and can work as a crucial parameter in various mechanical models to predict the moisture sensitivity and fatigue damage of asphalt mixtures. The calculated surface energy values of the aggregate minerals strongly depend on their surface roughness. Therefore, it is very relevant for accurate...journal article 2023

Gao, Mingyu (author), Chakraborty, S.S. (author), Kulahcioglu Ozkan, Burcu (author)The Probabilistic Concurrency Testing (PCT) algorithm that provides theoretical guarantees on the probability of detecting concurrency bugs does not apply to weak memory programs. The PCT algorithm builds on the interleaving semantics of sequential consistency, which does not hold for weak memory concurrency. It is because weak memory...conference paper 2023
