Fano-ADC(2,2) method for electronic decay rates

open access: yes, 2020
Fano-ADC is a family of ab initio methods for prediction of electronic decay widths in excited, singly- and doubly-ionized systems. It has been particularly successful in elucidating the geometry dependence of the inter-atomic decay widths in clusters ...

Differentiating between non-functioning pituitary macroadenomas and sellar meningiomas using ADC

open access: yesEndocrine Connections, 2020
Introduction and aim: It is difficult to distinguish between non-functioning pituitary macroadenomas (NFPMAs) and sellar meningiomas because of their overlapping imaging manifestations on routine MRI, especially in cases of meningiomas growing into the ...
