How enlightened self-interest guided global vaccine sharing benefits all: a modelling study

no code implementations13 Oct 2023 Zhenyu Han, Qianyue Hao, Qiwei He, Katherine Budeski, Depeng Jin, Fengli Xu, Kun Tang

We explore the possibility of the enlightened self-interest incentive mechanism, i. e., improving one's own epidemic outcomes by sharing vaccines with other countries, by evaluating the number of infections and deaths under various vaccine sharing strategies using the proposed model.

Multi-Scale Simulation of Complex Systems: A Perspective of Integrating Knowledge and Data

no code implementations17 Jun 2023 Huandong Wang, Huan Yan, Can Rong, Yuan Yuan, Fenyu Jiang, Zhenyu Han, Hongjie Sui, Depeng Jin, Yong Li

In this survey, we will systematically review the literature on multi-scale simulation of complex systems from the perspective of knowledge and data.

Genetic Meta-Structure Search for Recommendation on Heterogeneous Information Network

1 code implementation21 Feb 2021 Zhenyu Han, Fengli Xu, Jinghan Shi, Yu Shang, Haorui Ma, Pan Hui, Yong Li

To address these challenges, we propose Genetic Meta-Structure Search (GEMS) to automatically optimize meta-structure designs for recommendation on HINs.

Policy-Aware Mobility Model Explains the Growth of COVID-19 in Cities

no code implementations21 Feb 2021 Zhenyu Han, Fengli Xu, Yong Li, Tao Jiang, Depeng Jin, Jianhua Lu, James A. Evans

With the continued spread of coronavirus, the task of forecasting distinctive COVID-19 growth curves in different cities, which remain inadequately explained by standard epidemiological models, is critical for medical supply and treatment.
