Analysis of relative gene expression data using real-time quantitative

by Kenneth J. Livak, Thomas D. Schmittgen - PCR and 2 ���CT method. Methods 25 , 2001
"... of the target gene relative to some reference group The two most commonly used methods to analyze data from real-time, quantitative PCR experiments are absolute quantifica-such as an untreated control or a sample at time zero tion and relative quantification. Absolute quantification deter- in a time ..."

time-course study. mines the input copy number, usually by relating the PCR signal Absolute quantification should be performed in situ-to a standard curve. Relative quantification relates the PCR signal ations where it is necessary to determine the absolute of the target transcript in a treatment group

Calibrating noise to sensitivity in private data analysis

by Cynthia Dwork, Frank Mcsherry, Kobbi Nissim, Adam Smith - In Proceedings of the 3rd Theory of Cryptography Conference , 2006
"... Abstract. We continue a line of research initiated in [10, 11] on privacypreserving statistical databases. Consider a trusted server that holds a database of sensitive information. Given a query function f mapping databases to reals, the so-called true answer is the result of applying f to the datab ..."

the ith row of the database and g maps data-base rows to [0, 1]. We extend the study to general functions f, proving that privacy can be preserved by calibrating the standard deviation of the noise according to the sensitivity of the function f. Roughly speaking, this is the amount that any single

Duplicate Record Detection: A Survey

by Ahmed K. Elmagarmid, Panagiotis G. Ipeirotis, Vassilios S. Verykios , 2007
"... Often, in the real world, entities have two or more representations in databases. Duplicate records do not share a common key and/or they contain errors that make duplicate matching a difficult task. Errors are introduced as the result of transcription errors, incomplete information, lack of standa ..."

Transcriptional adaptation of Mycobacterium tuberculosis within macrophages: insights into the phagosomal environment

by Sabine Ehrt, Martin I. Voskuil, Yang Liu, Joseph A. Mangan, Irene M. Monahan, Gregory Dolganov, Brad Efron, Philip D. Butcher, Carl Nathan, Gary K. Schoolnik - J Exp Med , 2003
"... Little is known about the biochemical environment in phagosomes harboring an infectious agent. To assess the state of this organelle we captured the transcriptional responses of Mycobacterium tuberculosis (MTB) in macrophages from wild-type and nitric oxide (NO) synthase 2–deficient mice before and ..."

A Formal Framework for Linguistic Annotation

by Steven Bird, Mark Liberman - Speech Communication , 2000
"... `Linguistic annotation' covers any descriptive or analytic notations applied to raw language data. The basic data may be in the form of time functions -- audio, video and/or physiological recordings -- or it may be textual. The added notations may include transcriptions of all sorts (from pho ..."

Genome-wide discovery of transcriptional modules from DNA sequence and gene expression

by E. Segal, R. Yelensky, D. Koller - Bioinformatics , 2003
"... In this paper, we describe an approach for understanding transcriptional regulation from both gene expression and promoter sequence data. We aim to identify transcriptional modules—sets of genes that are co-regulated in a set of experiments, through a common motif profile. Using the EM algorithm, o ..."
Abstract - Cited by 122 (7 self) - Add to MetaCart
Saccharomyces cerevisiae gene expression data sets, showing that our approach is better than a standard one at recovering known motifs and at generating biologically coherent modules. We also combine our results with binding localization data to obtain regulatory relationships with known transcription factors

Using the amazon mechanical turk for transcription of spoken language

by Matthew R. Marge, Satanjeev Banerjee, Alexander I. Rudnicky, Matthew Marge, Satanjeev Banerjee, Er I. Rudnicky - In: Proc. ICASSP , 2010
"... We investigate whether Amazon’s Mechanical Turk (MTurk) service can be used as a reliable method for transcription of spoken language data. Utterances with varying speaker demographics (native and non-native English, male and female) were posted on the MTurk marketplace together with standard transc ..."

Polyphonic Audio Matching and Alignment for Music Retrieval

by Ning Hu, Roger B. Dannenberg, George Tzanetakis - in Proc. IEEE WASPAA , 2003
"... We describe a method that aligns polyphonic audio recordings of music to symbolic score information in standard MIDI files without the difficult process of polyphonic transcription. By using this method, we can search through the MIDI database to find the MIDI file corresponding to a polyphonic audi ..."
