[HTML][HTML] PCA outperforms popular hidden variable inference methods for molecular QTL mapping

HJ Zhou, L Li, Y Li, W Li, JJ Li - Genome biology, 2022 - Springer
Background Estimating and accounting for hidden variables is widely practiced as an important
step in molecular quantitative trait locus (molecular QTL, henceforth “QTL”) analysis for …

Dissecting gene expression heterogeneity: generalized Pearson correlation squares and the K-lines clustering algorithm

JJ Li, HJ Zhou, PJ Bickel, X Tong - Journal of the American …, 2024 - Taylor & Francis
Motivated by the pressing needs for dissecting heterogeneous relationships in gene expression
data, here we generalize the squared Pearson correlation to capture a mixture of linear …

Bipartite tight spectral clustering (BiTSC) algorithm for identifying conserved gene co-clusters in two species

YE Sun, HJ Zhou, JJ Li - Bioinformatics, 2021 - academic.oup.com
Motivation Gene clustering is a widely used technique that has enabled computational
prediction of unknown gene functions within a species. However, it remains a challenge to refine …

[HTML][HTML] ClipperQTL: ultrafast and powerful eGene identification method

HJ Zhou, X Ge, JJ Li - bioRxiv, 2023 - ncbi.nlm.nih.gov
A central task in expression quantitative trait locus (eQTL) analysis is to identify cis-eGenes (henceforth
“eGenes”), ie, genes whose expression levels are regulated by at least one local …

the relationship between genetic variants and molecular traits, helping explain findings in …

Energy intake and prostate tumor growth, angiogenesis, and vascular endothelial growth factor expression

…, AV Sotnikov, HJ Mangian, JR Zhou… - Journal of the …, 1999 - academic.oup.com
BACKGROUND: A sedentary lifestyle coupled with excessive energy intake is speculated to
be a factor associated with increased incidence of prostate cancer. We have investigated …

Towards verification of timed non-repudiation protocols

K Wei, J Heather - International Workshop on Formal Aspects in Security …, 2005 - Springer
… Fairness of non-repudiation is naturally expressed as a liveness specification, as in [Sch98];
to formalize this idea, we apply the process algebra CSP to analyze the well-known Zhou-…

Stitchr: stitching coding TCR nucleotide sequences from V/J/CDR3 information

JM Heather, MJ Spindler, MH Alonso… - Nucleic acids …, 2022 - academic.oup.com
The study and manipulation of T cell receptors (TCRs) is central to multiple fields across
basic and translational immunology research. Produced by V(D)J recombination, TCRs are …
