TrackSigFreq: subclonal reconstructions based on mutation signatures and allele frequencies
2020
Pacific Symposium on Biocomputing. Pacific Symposium on Biocomputing
Here we present an extension of this method, TrackSigFreq, which enables trajectory reconstruction based on both observed density of mutation frequencies and changes in mutational signature activities. ...
Mutational signatures are patterns of mutation types, many of which are linked to known mutagenic processes. Signature activity represents the proportion of mutations a signature generates. ...

Local sparse bump hunting reveals molecular heterogeneity of colon tumors
2011
Statistics in Medicine
In addition, thanks to the variable selection feature of the algorithm, we derived a novel sparse gene expression signature, which appears to divide all colon cancer patients into two populations: a population ...
This involves use of the local sparse bump hunting algorithm, which provides a much more optimal and biologically faithful transformed space within which to search for bumps. ...
For later use, let us denote by the partition of the input variable space S, generated by a CART partition algorithm, such that and ∩ r i ≠r j P r = ∅. ...

[article]
2011
arXiv
pre-print
Our solution is based on mutual authentication, and a fully distributed Autoconfiguration and CA model, in conjunction with threshold cryptography. ...
However, research primarily focused on correctness, efficiency and scalability; much less attention has been given to the security issues. ...
We assume a revocation scheme implemented within the MANET based on 'accusation' using threshold signatures [16] . ...

A New Query Integrity Verification Method with Cluster-based Data Transformation in Cloud Computing Environment
2015
International Journal of Smart Home
To solve the original data leakage problem, our clustering-based data transformation scheme is designed to select anchors based on data distribution. ...
A user compares the verification information with the cluster signatures stored in the verification index. ...
This is because our algorithm generates data groups based on the efficient data partition policy, such as anchor selection with data distribution, whereas the existing scheme clusters th em solely based ...

Analyzing the composition of cities using spatial clustering
2013
Proceedings of the 2nd ACM SIGKDD International Workshop on Urban Computing - UrbComp '13
We formally define the task of finding uniform regions in spatial data as a maximization problem of a plug-in measure of uniformity and introduce a prototype-based clustering algorithm named CLEVER to ...
Furthermore, algorithms for identifying popular distribution signatures and approaches for identifying regions which express a particular distribution signature will be presented. ...
Partitioning a city into uniform regions facilitates this task, as change can be analyzed based on higher level of granularity instead on the raw data. ...

Genomics, Proteomics & Bioinformatics
First, we used a NCI60 dataset to validate the ability of pathways to correctly partition samples. ...
Nevertheless, it remains unclear whether such function-based approaches are useful in deciphering molecular heterogeneities in cancers. ...
