Michael Mason prize essay 2003. Why do leucocytes accumulate within chronically inflamed joints?

Chronic inflammation is characterized by the accumulation of leucocytes within tissues. In rheumatoid arthritis the inflammatory infiltrate shares many architectural features with lymphoid tissue. For example, CD4 T cells and B cells accumulate in perivascular lymphoid structures within synovial tissue. CD8 T cells and neutrophils are found predominantly within synovial fluid. What drives these...

Hardware virtualization gives administrators the flexibility to rapidly create, destroy and relocate virtual machines across physical hosts. Unfortunately, the storage systems upon which these systems depend are not nearly as agile. To facilitate the rapid, safe development of block devices that can meet the needs of virtual machines, we present the Block Mason virtual block device framework. A...

In this talk we give combinatorial proofs of q-Stirling identities using restricted growth words. This includes a poset theoretic proof of Carlitz’s identity, a new proof of the q-Frobenius identity of Garsia and Remmel and of Ehrenborg’s Hankel q-Stirling determinantal identity. We also develop a two parameter generalization to unify identities of Mercier and include a symmetric function versi...

After specific activation by antigen, B cells differentiate into antibody-secreting plasma cells under the influence of a variety of factors (iymphokines) secreted by inducer/helper T cells (1-3). It is not yet clear how many lymphokines are specific for B cells but one, IL-2, has been shown to bind to both activated B cells and activated T cells (4-7), suggesting that at least one lymphokine r...
