deficiency that manifests as life threatening opportunistic infections and malignancies, i.e., the acquired immune deficiency syndrome (AIDS). The gut mucosa-associated lymphoid tissue (MALT, e.g., Peyer's patches) is a major locus of CD4+ cells. HIV's asymptomatic and insidious destruction of these cells compromises the integrity of the gut mucosa, allowing translocation (leakage) of microbes ...

Simple mathematical models for the competition between different virus variants in the presence of a crossreactive immune response show that, contrary to expectation, selection can favour variants that induce low viral loads. Here, Sebastian Bonhoeffer and Martin Nowak suggest that such 'competitively superior', but 'less pathogenic', mutants may be a possibility for post-exposure treatment of ...

Ordinal automata are used to model physical systems with Zeno behavior. Using automata and games techniques we solve a control problem formulated and left open by Demri and Nowak in 2005. It involves partial observability and a new synchronization between the controller and the environment.
