The Effect of Heterogeneity in Social Distancing on the Infection Peak for COVID-19
A compartmental model for COVID-19 with multiple subgroups that differ only in the level of contacts that members have with others was studied....

How Vaccination Helps to Relax the Population Mobility: An Agent-Based Model Approach
There is an ongoing debate on the relative impact of the various nonpharmaceutical interventions employed to limit the spread of coronavirus disease...

Geometry of fitness landscapes: peaks, shapes and universal positive epistasis
Darwinian evolution is driven by random mutations, genetic recombination (gene shuffling) and selection that favors genotypes with high fitness. For...

Modeling Ebola Transmission Dynamics with Media Effects on Disease and Isolation Rates
In this study, we developed a deterministic model for Ebola virus disease. The model uniquely incorporates isolated and non-isolated individuals as...

Variable stiffness tuned particle dampers for vibration control of cantilever boring bars
This research proposes a novel type of variable stiffness tuned particle damper (TPD) for reducing vibrations in boring bars. The TPD integrates the...
