Background Zipf's law and Heaps' law are two representatives of the scaling concepts,
which play a significant role in the study of complexity science. The coexistence of the Zipf's …

The emergence of novel respiratory pathogens can challenge the capacity of key health
care resources, such as intensive care units, that are constrained to serve only specific …

Over the past few decades, global metapopulation epidemic simulations built with worldwide
air-transportation data have been the main tool for studying how epidemics spread from the …

The spread of infectious diseases at the global scale is mediated by long-range human
travel. Our ability to predict the impact of an outbreak on human health requires …

An emerging disease is one infectious epidemic caused by a newly transmissible pathogen,
which has either appeared for the first time or already existed in human populations, having …

Epidemics, such as COVID-19, have caused significant harm to human society worldwide. A
better understanding of epidemic transmission dynamics can contribute to more efficient …

COVID-19, a global pandemic caused by the Severe Acute Respiratory Syndrome
Coronavirus 2 virus, has claimed millions of lives worldwide. Amid soaring contagion due to …

Hierarchical geographical traffic networks are critical for our understanding of scaling laws in
human trajectories. Here, we investigate the susceptible-infected epidemic process evolving …

Background Massive growth in human mobility has dramatically increased the risk and rate
of pandemic spread. Macro-level descriptors of the topology of the World Airline Network …

Epicentres are the focus of COVID‐19 research, whereas emerging regions with mainly
imported cases due to population movement are often neglected. Classical compartmental …
