Epitranscriptome and RNA Methylation: 

Epitranscriptome is an exciting new area that studies the mechanisms and functions of methylation in transcripts.


Decomposition of RNA methylome reveals co-methylation patterns induced by latent enzymatic regulators of the epitranscriptome. 
Despite the intriguing advancements, little is known so far about the dynamic landscape of RNA methylome across different cell types and how the epitranscriptome is regulated at the system level by enzymes, i.e., RNA methyltransferases and demethylases. To investigate this issue, a meta-analysis of m6A MeRIP-Seq datasets collected from 10 different experimental conditions (cell type/tissue or treatment) is performed.L Liu, SW Zhang, YC Zhang, H Liu, L Zhang, R Chen, Y Huang, J Meng Molecular BioSystems 11 (1), 262-274

Classification of imperfectly time-locked image RSVP events with EEG device
Classification based on EEG data in an RSVP experiment is considered. We consider here a more practical scenario that allows variation in response latency and develop a rigorous statistical formulation for modeling the uncertainty within the varying latency coupled with a likelihood ratio test (LRT) for classification.
