Expression profiling and cross-species RNA interference (RNAi) of desiccation-induced transcripts in the anhydrobiotic nematode Aphelenchus avenae
(2010-01-19)Abstract Background Some organisms can survive extreme desiccation by entering a state of suspended animation known as anhydrobiosis. The free-living mycophagous nematode Aphelenchus avenae can be induced to enter anhydrobiosis ...

Computational modeling of the EGFR network elucidates control mechanisms regulating signal dynamics
(2009-12-22)Abstract Background The epidermal growth factor receptor (EGFR) signaling pathway plays a key role in regulation of cellular growth and development. While highly studied, it is still not fully understood how the signal is ...

Selective Vectorization for Short-Vector Instructions
(2009-12-18)Multimedia extensions are nearly ubiquitous in today's general-purpose processors. These extensions consist primarily of a set of short-vector instructions that apply the same opcode to a vector of operands. Vector ...

The Video Mesh: A Data Structure for Image-based Video Editing
(2009-12-16)This paper introduces the video mesh, a data structure for representing video as 2.5D "paper cutouts." The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and ...

Perfect and General Virtual Implementation For Perfectly Informed Players
(2009-12-04)We show that, when the players are perfectly informed about each other, essentially all social-choice functions can be rationally robustly implemented via an extensive-form public-action mechanism that (1) is perfectly ...

Sufficient Conditions for Uniform Stability of Regularization Algorithms
(2009-12-01)In this paper, we study the stability and generalization properties of penalized empirical-risk minimization algorithms. We propose a set of properties of the penalty term that is sufficient to ensure uniform ?-stability: ...

A Unified Operating System for Clouds and Manycore: fos
(2009-11-20)Single chip processors with thousands of cores will be available in the next ten years and clouds of multicore processors afford the operating system designer thousands of cores today. Constructing operating systems for ...

Distributed Computation in Dynamic Networks
(2009-11-10)In this report we investigate distributed computation in dynamic networks in which the network topology changes from round to round. We consider a worst-case model in which the communication links for each round are chosen ...

Rational Robustness for Mechanism Design
(2009-11-10)The currently prevailing equilibrium-based approach to mechanism design suffers from a plurality of fundamental problems, and new conceptual frameworks are needed to solve or sufficiently alleviate them. In this paper, we ...

Graphite: A Distributed Parallel Simulator for Multicores
(2009-11-09)This paper introduces the open-source Graphite distributed parallel multicore simulator infrastructure. Graphite is designed from the ground up for exploration of future multicore processors containing dozens, hundreds, ...

Smartlocks: Self-Aware Synchronization through Lock Acquisition Scheduling
(2009-11-09)As multicore processors become increasingly prevalent, system complexity is skyrocketing. The advent of the asymmetric multicore compounds this -- it is no longer practical for an average programmer to balance the system ...

Automated home-cage behavioral phenotyping of mice
(2009-10-26)We describe a trainable computer vision system enabling the automated analysis of complex mouse behaviors. We provide software and a very large manually annotated video database used for training and testing the system. ...

Co-Clustering with Generative Models
(2009-11-03)In this paper, we present a generative model for co-clustering and develop algorithms based on the mean field approximation for the corresponding modeling problem. These algorithms can be viewed as generalizations of the ...

Propagation Networks: A Flexible and Expressive Substrate for Computation
(2009-11-03)I propose a shift in the foundations of computation. Practically all ideas of general-purpose computation today are founded either on execution of sequences of atomic instructions, i.e., assembly languages, or on evaluation ...

Iterative Projection Methods for Structured Sparsity Regularization
(2009-10-14)In this paper we propose a general framework to characterize and solve the optimization problems underlying a large class of sparsity based regularization algorithms. More precisely, we study the minimization of learning ...

Understanding and Supporting Directed Content Sharing on the Web
(2009-10-07)To find interesting, personally relevant web content, we often rely on friends and colleagues to pass links along as they encounter them. In this paper, we study and augment link-sharing via e-mail, the most popular means ...

Notes on the Shannon Entropy of the Neural Response
(2009-10-09)In these notes we focus on the concept of Shannon entropy in an attempt to provide a systematic way of assessing the discrimination properties of the neural response, and quantifying the role played by the number of layers ...

A Bayesian inference theory of attention: neuroscience and algorithms
(2009-10-03)The past four decades of research in visual neuroscience has generated a large and disparate body of literature on the role of attention [Itti et al., 2005]. Although several models have been developed to describe specific ...
