Dr. Horvath will present a comprehensive DNA methylation dataset that may intrigue computational scientists, longevity experts, and researchers interested in epigenetics and DNA methylation. This dataset encompasses n=15,456 DNA methylation samples obtained from 70 tissue types across 348 mammalian species, generated using the mammalian methylation array (A. Arneson, Jason Ernst 2022). The research team studied whether methylation levels of cytosines (CpGs) in conserved DNA sequences across species would enable the creation of a phylo-epigenetic tree.
Predicting the taxonomic affiliation of DNA sequences collected from biological samples is a fundamental step in biodiversity assessment. This task is performed by leveraging existing databases containing reference DNA sequences endowed with a taxonomic identification. However, environmental sequences can be from organisms that are either unknown to science or for which there are no reference sequences available. Thus, the taxonomic novelty of a sequence needs to be accounted for when doing classification.
Members of the community are invited to attend an opening event for the Double Jeopardy Transmedia Project Exhibition which includes a panel discussion on student activism against sexual violence on college campuses across Los Angeles, featuring student activist leaders from UCLA, USC, and Occidental college, as well as expert speakers and professionals in the field.
Attendees will also have the opportunity to view works of art created by UC students who share their experiences related to sexual violence and anti-Asian racism.
Real data are unlikely to be exactly normally distributed. For better estimation and inference with non-normal data, I work on multiple projects in recent years. In terms of estimation, my collaborators and I propose a distributionally weighted least squares (DLS) estimator for parameter estimation (Du & Bentler, 2022; Du et al., 2022). We find that DLS works well with both normal and non-normal data in both factor analysis and growth curve models. We currently are exploring different ways to estimate DLS including bootstrapping and asymptotic methods.
We look forward to celebrating our 2023 graduates!
