This article explores three critical topics discussed in the recent debate over concurrency (overlapping sexual partnerships): measurement of the prevalence of concurrency, mathematical modelling of concurrency and HIV epidemic dynamics, and measuring the correlation between HIV and concurrency. The focus of the article is the concurrency hypothesis - the proposition that presumed high prevalen...

Diseases spread over temporal networks of interaction events between individuals. Structures these hold the keys to understanding epidemic propagation. One early concept literature aid in discussing structures is concurrency -- quantifying individuals' tendency form time-overlapping "partnerships". Although conflicting evaluations and an overabundance operational definitions have marred history...

One of the most important decisions about the architecture of a server program is its concurrency mechanisms. However, a good concurrency model for general-purpose server programs is increasingly difficult to conceive as the runtime conditions are hard to predict. In this work, we advocate that the concurrency code is to be decoupled from server programs. To enable such separation, we propose a...
