We give an exponential lower bound for the Graver complexity of the incidence matrix of a complete bipartite graph of arbitrary size. Our result is a generalization of the result by Berstein and Onn (...
Inference in incidence, infection, and impact: Co-infection of multiple hosts by multiple pathogens

A large literature concerns the epidemiology of single pathogens on single hosts. Yet in some environmental applications, such as fungal pathogens of forest tree seedlings, the “one host-one...

For many diseases, logistic and other constraints often render large incidence
studies difficult, if not impossible, to carry out. This becomes a drawback,
particularly when a new incidence study is...
