MaCH-Admix: Genotype Imputation for Admixed Populations
, 2012
"... ABSTRACT: Imputation in admixed populations is an important problem but challenging due to the complex linkage disequilibrium (LD) pattern. The emergence of large reference panels such as that from the 1,000 Genomes Project enables more accurate imputation in general, and in particular for admixed p ..."

A Novel Approach to Structure Alignment
- Protein Sci
, 2000
"... Motivation: Aligning protein structures is a highly relevant task. It enables the study of functional and ancestry relationships between proteins and is very important for homology and threading methods in structure prediction. Existing methods typically only partially explore the space of possible ..."

(2) Minimization of the error function by an iterative method, where in each iteration a mean field method is employed for the assignment variables and exact rotation/translation of atomic coordinates is performed, weighted with the corresponding assignment variables.

A Network-Based Approach to Prioritize Results from Genome-Wide Association Studies. PloS one 6: e24220
, 2011
"... Genome-wide association studies (GWAS) are a valuable approach to understanding the genetic basis of complex traits. One of the challenges of GWAS is the translation of genetic association results into biological hypotheses suitable for further investigation in the laboratory. To address this challe ..."

Efficient learning of microbial genotype-phenotype association rules
- Bioinformatics
, 2010
"... Motivation: Finding biologically causative genotype-phenotype associations from whole-genome data is difficult due to the large gene feature space to mine, the potential for interactions among genes and phylogenetic correlations between genomes. Associations within phylogentically distinct organisms ..."

A Nonlinear Hierarchical Model for Estimating Prevalence Rates with Small Samples
"... Estimating prevalence rates with small weighted sam-ples, especially for rare diseases is a challenging task. We encountered such a situation in the recent Na-tional Latino and Asian American Study (NLAAS) on mental health. Due to small sizes of the weighted samples in various age groups, the standa ..."

Diversity and selection in sorghum: simultaneous analyses using simple sequence repeats.
- Theor. Appl. Genet.
, 2005
"... Abstract Although molecular markers and DNA sequence data are now available for many crop species, our ability to identify genetic variation associated with functional or adaptive diversity is still limited. In this study, our aim was to quantify and characterize diversity in a panel of cultivated ..."

We anticipate that such population genetics-based statistical approaches will be useful for re-evaluating extant SSR data for mining interesting genomic regions from

INVESTIGATION Inferring Admixture Histories of Human Populations Using Linkage Disequilibrium
"... ABSTRACT Long-range migrations and the resulting admixtures between populations have been important forces shaping human genetic diversity. Most existing methods for detecting and reconstructing historical admixture events are based on allele frequency divergences or patterns of ancestry segments in ..."

Here, we comprehensively develop LD-based inference into a versatile tool for investigating admixture. We present a new weighted LD
