Brain structural covariance networks in obsessive-compulsive disorder: a graph analysis from the ENIGMA Consortium

open access: yesBrain : a journal of neurology, 2020
In the largest brain structural covariance study of OCD to date, Yun et al. show a less segregated organization of structural covariance networks and a reorganization of brain hubs, including cingulate and orbitofrontal regions, in OCD.

The Combination of DAT-SPECT, Structural and Diffusion MRI Predicts Clinical Progression in Parkinson’s Disease

open access: yesFrontiers in Aging Neuroscience, 2019
There is an increasing interest in identifying non-invasive biomarkers of disease severity and prognosis in idiopathic Parkinson’s disease (PD). Dopamine-transporter SPECT (DAT-SPECT), diffusion tensor imaging (DTI), and structural magnetic resonance ...

Covariance analysis of symmetry energy observables from heavy ion collision [PDF]

open access: yes, 2015
Using covariance analysis, we quantify the correlations between the interaction parameters in a transport model and the observables commonly used to extract information of the Equation of State of Asymmetric Nuclear Matter in experiments.
