MRI brain scans help identify effective use of self-guided anxiety app
By understanding differences in how people’s brains are wired, clinicians may be able to predict who would benefit from a self-guided anxiety care app, according to a new analysis from a clinical trial led by Weill Cornell Medicine…

Study sheds light on molecular mechanisms of brain aging
Aging and neurodegeneration are both known to disrupt the production of functional proteins in cells – a process called “proteostasis,” or protein homeostasis. Brain cells in particular fall prey to proteostasis disruptions, which…

Critical velocity criterion of explosive charges initiated by fragment impact considering impact angle and charge radius
Numerical simulation model
In the case of interaction between fragments and explosive charges, there were both deformation processes of fragments and explosive charges, as well as the shock initiation process of explosives. The Lagrange algorithm…

The molecular basis of lamin-specific chromatin interactions
Statistics and reproducibility
No statistical methods were used to predetermine sample size. No data were excluded from the analyses. The data met the assumptions of the statistical tests used; normality and equal variances were formally tested. The…
