SNAP MRI Reveals Association Between Distal Cerebral Arterial Flow and Cognitive Function in an Aging Population

This study shows that SNAP MRI measurements of distal cerebral arterial flow correlate with cognitive function in aging individuals, suggesting their value in assessing cerebrovascular health.

Large-Scale Hypothesis Testing for Causal Mediation Effects with Applications in Genome-wide Epigenetic Studies

The paper develops a new statistical test, DACT, to detect mediation effects in genome-wide epigenetic studies and applies it to identify DNA methylation sites mediating smoking's effect on lung function.

Dynamic Scan Procedure for Detecting Rare-Variant Association Regions in Whole Genome Sequencing Studies

The paper introduces SCANG, a dynamic scan statistic method for detecting rare-variant association regions in WGS data without pre-specifying window sizes, showing improved performance over existing methods.
