PA*SE: Parallel A* for Slow Expansions

Planners need to become faster as we seek to tackle increasingly complicated problems. Much of the recent improvements in computer speed is due to multi-core processors. For planners to take advantage of these types of architectures, we must adapt algorithms for parallel processing. There are a number of planning domains where state expansions are slow. One example is robot motion planning, whe...

Rare-Allele Detection Using Compressed Se(que)nsing

Detection of rare variants by resequencing is important for the identification of individuals carrying disease variants. Rapid sequencing by new technologies enables low-cost resequencing of target regions, although it is still prohibitive to test more than a few individuals. In order to improve cost trade-offs, it has recently been suggested to apply pooling designs which enable the detection ...

2013 William Allan Award: My multifactorial journey.

I want to begin by expressing my sincerest appreciation to The American Society of Human Genetics (ASHG) for this wonderful recognition and award; Vivian Cheung, Evan Eichler, and Stanislas Lyonnet for their nominations; and Evan Eichler for his very kind introduction. I want to thank each of you who are here today and particularly my wife and my daughters, who seldom get to hear what I have be...

PUMAS: Un Framework que Adapta la Información en Ambientes Ubicuos

Mobile Devices (MD) are characterized by intrinsic reduced capacities (e.g., size of screen, memory, data storage). PUMAS (Peer Ubiquitous Multi-Agent System) is a framework based on agents whose main objective is to provide nomadic users with information adapted to different criteria (their preferences, their location, etc.) when they access Web-based Information Systems (WIS) using such MD. P...
