This paper introduces InvGraphCox, a framework that improves survival prediction by learning invariant graph representations under distribution shifts, outperforming baselines in discrimination and risk stratification.

This study uses simulation and sequencing data to show that multiple SARS-CoV-2 variants can coexist in COVID-19 patients, with an increase in the number of coinfected variants over time.

CovProfile identifies viral genomic variations and gene expressions from SARS-CoV-2 Nanopore sequences, revealing multiple strains and high expression of viral genes in patient samples.
