Decreased gyrification in major depressive disorder
TL;DR: Compared with healthy participants, patients with major depressive disorder showed significantly decreased local gyrification index in the bilateral mid-posterior cingulate, insula, and orbital frontal cortices, the left anterior cingulated cortex, and the right temporal operculum.

Sparse recovery via nonconvex regularized $M$-estimators over $\ell_q$-balls
TL;DR: In this paper, the recovery properties of non-convex regularized $M$-estimators, under the assumption that the true parameter is of soft sparsity, were analyzed.

Reliable heritability estimation using sparse regularization in ultrahigh dimensional genome-wide association studies.
TL;DR: This paper investigates the influences of the fixed and random effect assumption on heritability estimation, and proposes a two-stage strategy by first performing sparse regularization via cross-validated elastic net, and then applying variance estimation methods to construct reliable heritability estimations.
New Insights into Signed Path Coefficient Granger Causality Analysis
TL;DR: The findings suggested that the applicability of this kind of causality analysis was rather limited, hence researchers should be more cautious in applying the signed path coefficient Granger causality to fMRI data to avoid misinterpretation.
