TwinPurify: Purifying gene expression data to reveal tumor-intrinsic transcriptional programs via self-supervised learning
Zhiwei Zheng, Kevin Bryson
Advances in single-cell and spatial transcriptomic technologies have transformed tumor ecosystem profiling at cellular resolution. However, large scale studies on patient cohorts c…
LaCoGSEA: Unsupervised deep learning for pathway analysis via latent correlation
Zhiwei Zheng, Kevin Bryson
Motivation: Pathway enrichment analysis is widely used to interpret gene expression data. Standard approaches, such as GSEA, rely on predefined phenotypic labels and pairwise compa…
A Lemma on Leech-like Lattices
Zhiwei Zheng
A Leech pair is defined as a pair , where is a positive definite even lattice without roots, equipped with a faithful action of a finite group , such that the invaria…
Finite Groups of Symplectic Automorphisms of Supersingular K3 surfaces in Odd Characteristics
Bin Wang, Zhiwei Zheng
In 2009, Dolgachev-Keum showed that finite groups of tame symplectic automorphisms of K3 surfaces in positive characteristics are subgroups of the Mathieu group of degree 23. In th…
