This paper develops a multiple sampling scheme to construct stable brain metabolic networks from PET data, showing improved stability and reduced subject requirements compared to conventional methods.

This study investigates how long- and short-range white matter fiber depletion contributes to cognitive deficits in fronto-temporal dementia using diffusion MRI and voxel-based morphometry.

This paper introduces Constrained Instrumental Variable (CIV) methods to improve Mendelian randomization by handling pleiotropy, showing better performance in simulations and application to ADNI data.
