A continuum model for the unfolding of von Willebrand Factor

no code implementations5 Aug 2021 Mansur Zhussupbekov, Rodrigo Mendez Rojano, Wei-Tao Wu, Mehrdad Massoudi, James F. Antaki

vWF unfolding takes place via two regimes: tumbling in simple shear and strong unfolding in flows with dominant extensional component.

no code implementations10 Dec 2020 Anjana Jayaraman, Junhyuk Kang, Megan A. Jamiolkowski, William R. Wagner, Brian J. Kirby, James F. Antaki

Additionally, we observed embolization when thrombus areas exceeded 300{\mu}m2, which was dependent on the combination of shear, ADP concentration, and material surface.

Limitations of ROC on Imbalanced Data: Evaluation of LVAD Mortality Risk Scores

no code implementations29 Oct 2020 Faezeh Movahedi, Rema Padman, James F. Antaki

Methods: This study compared the ROC and PRC for the outcome of two classifiers for 90-day LVAD mortality for 800 patients (test group) recorded in INTERMACS who received a continuous-flow LVAD between 2006 and 2016 (mean age of 59 years; 146 females vs. 654 males) in which mortality rate is only %8 at 90-day (imbalanced data).
