We consider the ultrasound imaging problem governed by a nonlinear wave equation of
Westervelt type with variable wave speed. We show that the coefficient of nonlinearity can …

We consider an inverse problem arising in nonlinear ultrasound imaging. The propagation
of ultrasound waves is modeled by a quasilinear wave equation. We make measurements at …

In this paper, we consider an inverse problem for a nonlinear wave equation with a damping
term and a general nonlinear term. This problem arises in nonlinear acoustic imaging and …

Congenital heart disease (CHD) is a term for a heterogeneous group of abnormalities in
cardiac morphogenesis present at birth. Early diagnosis and proper care reduce the …

Background The number of pediatric patients who survive open-heart surgery has increased
in recent years and the complications seen in this patient group continue to decrease with …

Children with congenital heart disease, particularly congenital heart surgery survivors, are
known to face important neurodevelopmental and psychosocial challenges throughout their …

Congenital heart disease (CHD) is the most prevalent congenital malformation, with about
one million births impacted worldwide per year. Comprehensive investigation of this disease …

Advancements in infant cardiovascular surgery have resulted in a significant decrease in
mortality of many newborns with congenital heart disease (CHD); however …

Background: We assessed the relationship between postoperative cognitive impairment and
cerebral oximetry (INVOS) and mixed venous oxygen saturation (SvO2) during …

Cardiac surgery in the neonate in most cases is undertaken for the treatment of congenital
heart disease (CHD). Extremely rare is the need for surgical intervention for other conditions …
