How microtubule-associated motor proteins are regulated is not well understood. A potential mechanism for spatial regulation of motor proteins is provided by posttranslational modifications of tubulin subunits that form patterns on microtubules. Glutamylation is a conserved tubulin modification  that is enriched in axonemes. The enzymes responsible for… (More)

As sponsored search becomes increasingly important as an advertising medium for firms, search engines are exploring more advanced bidding and ranking mechanisms to increase their revenue from sponsored search auctions. For instance, Google, Yahoo! and Bing are investigating auction mechanisms in which each advertiser submits two bids: one bid for the… (More)
Dynein light chains are required for the assembly of axonemal dyneins into cilia and flagella. Most organisms express a single p28 dynein light chain and four to nine one-headed inner arm dynein heavy chains. In contrast, Tetrahymena encodes three p28 dynein light chain genes (p28A, p28B, and p28C) and 18 one-headed inner arm dynein heavy chains. In this… (More)

This paper investigates a class of matching problems—the assignment of indivisible items to agents where some agents have prior claims to some of the items. As a running example, we will refer to the indivisible items as houses. House allocation problems are not only of theoretical interest, but also of practical importance. A house allocation mechanism… (More)
