A Method for Imaging the Ischemic Penumbra with MRI using IVIM
Autor: Liu, Mira M., Saadat, Niloufar, Roth, Steven P., Niekrasz, Marek A., Giurcanu, Mihai, Shazeeb, Mohammed Salman, Carroll, Timothy J., Christoforidis, Gregory A.
This work examines the hypothesis that intravoxel incoherent motion MRI (IVIM) can quantify local cerebral blood flow (qCBF), infarct volume, and define the ischemic penumbra for determination of the perfusion-diffusion mismatch (PWI/DWI) volume in a

Fair and Truthful Allocations Under Leveled Valuations
Autor: Christodoulou, George, Christoforidis, Vasilis
We study the problem of fairly allocating indivisible goods among agents which are equipped with {\em leveled} valuation functions. Such preferences, that have been studied before in economics and fair division literature, capture a simple and intuit

On The Pursuit of EFX for Chores: Non-Existence and Approximations
Autor: Christoforidis, Vasilis, Santorinaios, Christodoulos
We study the problem of fairly allocating a set of chores to a group of agents. The existence of envy-free up to any item (EFX) allocations is a long-standing open question for both goods and chores. We resolve this question by providing a negative a

Quantification of Collateral Supply with Local-AIF Dynamic Susceptibility Contrast MRI Predicts Infarct Growth
Autor: Liu, Mira M., Saadat, Niloufar, Roth, Steven P., Niekrasz, Marek A., Giurcanu, Mihai, Carroll, Timothy J., Christoforidis, Gregory A.
In ischemic stroke, leptomeningeal collaterals can provide compensatory blood flow to tissue at risk despite an occlusion, and impact treatment response and infarct growth. The purpose of this work is to test the hypothesis that local perfusion with
