TSYS School Faculty Trailblazers

Modeling COVID-19 Infections and Recoveries

New research by TSYS School computer scientist Linqiang Ge and his colleagues Yuexin Li, Yang Zhou and Jingyi Zheng of Auburn University, and Xuan Cao of the University of Cincinnati mathematically describes the dynamic of the COVID-19 pandemic, taking immunity, reinfection, and vaccination into account in a way that not only predicts the number of cases, but also monitors the trajectories of changing parameters, such as transmission rate, recovery rate, and the basic reproduction number. Their study, which appears in a 2021 issue of Frontiers in Artificial Intelligence, finds a significant decrease in the transmission rate in the U.S. after authorities announced a series of orders aiming to prevent the spread of the virus, such as closing non-essential businesses and lockdown restrictions. Later, as restrictions were gradually lifted, their analysis detects a new surge of infection as transmission rates show increasing trends in some states. As Ge stated to Turner Business, “using our epidemiology models, people can track, timely monitor, and predict the COVID-19 pandemic with precision.” The researchers validated their models using both national- and state-level data, and the resulting relative prediction errors for the infected group and recovered group are generally less than 0.5 percent. “We also simulate the long-term development of the pandemic based on our proposed models to explore when the crisis will end under certain conditions,” Ge added.

TSYS School, Jianhua Yang, Lixin Wang Each among Top Five in the World

New research by computer scientists in the School of Information Technology at Universiti Utara Malaysia that ranks institutions and individuals on the basis of scholarship in the area of stepping-stone attacks heaps praise on the Turner College’s TSYS School of Computer Science and two of its faculty – Jianhua Yang and Lixin Wang . The article, published in the April 2023 issue of the International Journal of Research in Engineering and Science , provides a bibliometric analysis of both publication and citation data from 2000 to September of 2022 related to research on stepping-stone intrusion. Among several results, it reports that Columbus State University ranks second worldwide, trailing only the University of Houston, using total publications on the subject as the basis of comparison. A number of other U.S. institutions appear in the top 10, including third-ranked North Carolina State University, fourth-ranked University of Illinois, sixth-ranked Iowa State U...
