Dynamic optimality for skip lists and B-trees
Sleator and Tarjan [39] conjectured that splay trees are dynamically optimal binary search trees (BST). In this context, we study the skip list data structure introduced by Pugh [...

Query processing techniques for solid state drives
Solid state drives perform random reads more than 100x faster than traditional magnetic hard disks, while offering comparable sequential read and write bandwidth. Because of their...

Cache Conscious Indexing for Decision-Support in Main Memory
As random access memory gets cheaper, it becomes increasingly affordable to build computers with large main memories. We consider decision support workloads within the context of...

Binary Queries and XML Transformations
: We present a grammar-based approach to specifying k-ary queries for XML documents. k-ary queries simultaneously locate k nodes of an input tree as specified by a given relation. ...

The Kesten-Stigum Reconstruction Bound Is Tight for Roughly Symmetric Binary Channels
We establish the exact threshold for the reconstruction problem for a binary asymmetric channel on the b-ary tree, provided that the asymmetry is sufficiently small. This is the ...
