Grahic Jump Location
Regression of dW/dIIB against IIB-3 using the uniaxial testing data
Grahic Jump Location
Cross-sectional cut of intraluminal thrombus (above) and representative scanning electron micrograph from the three different regions (bottom). The red color region is the luminal layer, the white color region is the medial layer, and the dark brown region is the abluminal layer. The luminal surface which is the newly formed ILT (A), the medial region (B), and the abluminal region near the AAA wall where the ILT is the most “aged” (C).
Grahic Jump Location
Typical set of T–λ curves for ILT samples taken from the luminal region (upper set of curves) and the medial region (lower set of curves). All data were obtained from the same ILT (same patient).
Grahic Jump Location
Group data (mean±SEM) from surface layer and fit to the constitutive model given by Eq. (5).
