Representing Uncertainty about Complex User Goals in Statistical Dialogue Systems
We point out several problems in scalingup statistical approaches to spoken dialogue systems to enable them to deal with complex but natural user goals, such as disjunctive and ne...

From a static impossibility to an adaptive lower bound: the complexity of early deciding set agreement
Set agreement, where processors decisions constitute a set of outputs, is notoriously harder to analyze than consensus where the decisions are restricted to a single output. This ...

Efficient representation of cortical convolutions for the analysis of brain surface topology
Various time efficient procedures were developed allowing to calculate planar representations of the brain in MR and CT clearly conveying the whole surface topology. For the compar...

A network perspective on the topological importance of enzymes and their phylogenetic conservation
Background: A metabolic network is the sum of all chemical transformations or reactions in the cell, with the metabolites being interconnected by enzyme-catalyzed reactions. Many ...

The Shannon capacity of a graph and the independence numbers of its powers
The independence numbers of powers of graphs have been long studied, under several definitions of graph products, and in particular, under the strong graph product. We show that t...
