Efficient calibration of the shifted square-root diffusion model to credit default swap spreads using asymptotic approximations

Autor: Agarwal, Ankush, Liao, Ying

We derive a closed-form approximation for the credit default swap (CDS) spread in the two-dimensional shifted square-root diffusion (SSRD) model using asymptotic coefficient expansion technique to approximate solutions of nonlinear partial differenti

Assessment of Precision and Accuracy of Brain White Matter Microstructure using Combined Diffusion MRI and Relaxometry

Autor: Coelho, Santiago, Liao, Ying, Szczepankiewicz, Filip, Veraart, Jelle, Chung, Sohae, Lui, Yvonne W., Novikov, Dmitry S., Fieremans, Els

Joint modeling of diffusion and relaxation has seen growing interest due to its potential to provide complementary information about tissue microstructure. For brain white matter, we designed an optimal diffusion-relaxometry MRI protocol that samples

Volume electron microscopy in injured rat brain validates white matter microstructure metrics from diffusion MRI

Autor: Coronado-Leija, Ricardo, Abdollahzadeh, Ali, Lee, Hong-Hsi, Coelho, Santiago, Ades-Aron, Benjamin, Liao, Ying, Salo, Raimo A., Tohka, Jussi, Sierra, Alejandra, Novikov, Dmitry S., Fieremans, Els

Biophysical modeling of diffusion MRI (dMRI) offers the exciting potential of bridging the gap between the macroscopic MRI resolution and microscopic cellular features, effectively turning the MRI scanner into a noninvasive in vivo microscope. In bra

Mapping tissue microstructure of brain white matter in vivo in health and disease using diffusion MRI

Autor: Liao, Ying, Coelho, Santiago, Chen, Jenny, Ades-Aron, Benjamin, Pang, Michelle, Osorio, Ricardo, Shepherd, Timothy, Lui, Yvonne W., Novikov, Dmitry S., Fieremans, Els

Publikováno v: Imaging Neuroscience, 2, 1-17, 2024

Diffusion magnetic resonance imaging offers unique in vivo sensitivity to tissue microstructure in brain white matter, which undergoes significant changes during development and is compromised in virtually every neurological disorder. Yet, the challe
