Model-Based Analysis of Oligonucleotide Arrays: Model Validation, Design Issues and Standard Error Application

by Cheng Li, Wing Hung Wong , 2001
"... Background: A model-based analysis of oligonucleotide expression arrays we developed previously uses a probe-sensitivity index to capture the response characteristic of a specific probe pair and calculates model-based expression indexes (MBEI). MBEI has standard error attached to it as a measure of ..."

better ranking statistic for filtering genes. We can assign reliability indexes for genes in a specific cluster of interest in hierarchical clustering by resampling clustering trees. A software dChip implementing many of these analysis methods is made available. Conclusions: The model-based approach

Dynamic taint analysis for automatic detection, analysis, and signature generation of exploits on commodity software

by James Newsome, Dawn Song - In Network and Distributed Systems Security Symposium , 2005
"... Software vulnerabilities have had a devastating effect on the Internet. Worms such as CodeRed and Slammer can compromise hundreds of thousands of hosts within hours or even minutes, and cause millions of dollars of damage [32, 51]. To successfully combat these fast automatic Internet attacks, we nee ..."

Image Parsing: Unifying Segmentation, Detection, and Recognition

by Zhuowen Tu, Xiangrong Chen, Alan L. Yuille, Song-Chun Zhu , 2005
"... In this paper we present a Bayesian framework for parsing images into their constituent visual patterns. The parsing algorithm optimizes the posterior probability and outputs a scene representation in a "parsing graph", in a spirit similar to parsing sentences in speech and natural lang ..."

language. The algorithm constructs the parsing graph and re-configures it dynamically using a set of reversible Markov chain jumps. This computational framework integrates two popular inference approaches -- generative (top-down) methods and discriminative (bottom-up) methods. The former formulates

Vision-Based Navigation by a Mobile Robot with Obstacle Avoidance using Single-Camera Vision and Ultrasonic Sensing

by Akihisa Ohya, Akio Kosaka, Avinash Kak, J. Borenstein , 1998
"... This paper describes a vision-based navigation method in an indoor environment for an autonomous mobile robot which can avoid obstacles. In this method, the self-localization of the robot is done with a model-based vision system, and nonstop navigation is realized by a retroactive position correctio ..."

Quantitative mass spectrometric multiple reaction monitoring assays for major plasma proteins.

by Leigh Anderson , Christie L Hunter - Mol. Cell. Proteomics , 2006
"... Quantitative LC-MS/MS assays were designed for tryptic peptides representing 53 high and medium abundance proteins in human plasma using a multiplexed multiple reaction monitoring (MRM) approach. Of these, 47 produced acceptable quantitative data, demonstrating within-run coefficients of variation ..."

of disease, risk, and therapeutic response. Candidate-based specific assays rely on the specificity of capture or detection methods to select a specific molecule as analyte. Capture reagents such as antibodies can provide extreme specificity (particularly when two different antibodies are used as in a

Real time obstacle detection in stereovision on non flat road geometry through V-disparity representation. Pages 646–651 of: Procs

by Raphael Labayrade, Didier Aubert - Proc. SPIE 238. 71 136 version 1 - 9 Sep 2011 LeGuilloux , 2002
"... Abstract — Many roads are not totaly planar and often present hills and valleys because of environment topography. Nevertheless, the majority of existing techniques for road obstacle detection using stereovision assumes that the road is planar. This can cause several issues: imprecision as regards t ..."
