T lymphocytes sense antigens within seconds and make a decision within one minute.
Adaptive immune responses are triggered by the rapid and sensitive detection of MHC-bound peptides by TCRs. The kinetics of early TCR/APC contacts are incompletely known. In this study, we used total internal reflection fluorescence microscopy to image human T cell membranes near model surfaces: contact was mediated by mobile protrusions of <0.4 μm diameter. The mean lifetime of contacts with a...
متن کاملPhylogenetic diversity within seconds.
We consider a (phylogenetic) tree with n labeled leaves, the taxa, and a length for each branch in the tree. For any subset of k taxa, the phylogenetic diversity is defined as the sum of the branch-lengths of the minimal subtree connecting the taxa in the subset. We introduce two time-efficient algorithms (greedy and pruning) to compute a subset of size k with maximal phylogenetic diversity in ...

متن کاملARTEMIS: Neutralizing BGP Hijacking within a Minute
BGP prefix hijacking is a critical threat to Internet organizations and users. Despite the availability of several defense approaches (ranging from RPKI to popular third-party services), none of them solves the problem adequately in practice. They suffer from: (i) lack of detection comprehensiveness, allowing sophisticated attackers to evade detection, (ii) limited accuracy, especially in the c...
متن کاملContext within Common Sense
There exists many software applications that attempt to use common sense reasoning to assist users do everyday tasks, such as schedule their day or write emails. One such program is ARIA, which relies on the information in OpenMind’s common sense database. However, these applications are only as useful as the quality of the common sense information with which they are reasoning. One vast improv...
