He, Y. (author), Chen, J.Y. (author), Knab, J.R. (author), Zheng, W. (author), Markelz, A.G. (author)We investigate the presence of structural collective motions on a picosecond timescale for the heme protein, cytochrome c, as a function of oxidation and hydration, using terahertz (THz) time domain spectroscopy and molecular dynamics simulations. The THz response dramatically increases with oxidation, with the largest increase for lowest...journal article 2011

Zhang, Qingzhou (author), Zheng, Feifei (author), Kapelan, Z. (author), Savic, Dragan (author), He, Guilin (author), Ma, Yiyi (author)Water quality sensors are often spatially distributed in water distribution systems (WDSs) to detect contamination events and monitor quality parameters (e.g., chlorine residual levels), thereby ensuring safety of a WDS. The performance of a water quality sensor placement strategy (WQSPS) is not only affected by sensor spatial deployment that...journal article 2020

Tang, Wenfu (author), Emmons, Louisa K. (author), Worden, Helen M. (author), Kumar, Rajesh (author), He, Cenlin (author), Gaubert, Benjamin (author), Zheng, Zhonghua (author), Tilmes, Simone (author), Levelt, Pieternel Felicitas (author)The Multi-Scale Infrastructure for Chemistry and Aerosols Version 0 (MUSICAv0) is a new community modeling infrastructure that enables the study of atmospheric composition and chemistry across all relevant scales. We develop a MUSICAv0 grid with Africa refinement (∼ 28 km × 28 km over Africa). We evaluate the MUSICAv0 simulation for 2017 with in...journal article 2023

Li, Meng (author), Shen, Yanzhe (author), Ye, Guixin (author), He, Jialing (author), Zheng, Xin (author), Zhang, Zijian (author), Zhu, Liehuang (author), Conti, M. (author)Digital forensics is crucial to fight crimes around the world. Decentralized Digital Forensics (DDF) promotes it to another level by channeling the power of blockchain into digital investigations. In this work, we focus on the privacy and security of DDF. Our motivations arise from (1) how to track an anonymous- and-malicious data user who...journal article 2024

Zheng, Kaifeng (author), Feng, Xiaoyang (author), He, Xiaohui (author), Heng, J. (author), Li, Le (author), Wang, Hongfu (author)In order to improve the fatigue resistance of orthotropic steel decks (OSDs), the steel bridge deck was annealed to reduce the welding residual stress of key welds. This work at first presented a systematical review and discussion over the distribution pattern of welding residual stress in OSDs, in accordance with a conceptual analysis...journal article 2024
