Serum bile acids as a prognostic biomarker in biliary atresia following Kasai portoenterostomy
Hepatology, EarlyView., 2022 Serum bile acid levels predict outcomes in patients with biliary atresia who achieve normalized bilirubin levels after Kasai portoenterostomy. Abstract Background and Aims In biliary atresia, serum bilirubin is commonly used to predict outcomes after Kasai portoenterostomy (KP).

Advances in Mathematical Physics, 2019 We consider a dam-water system modeled as a fluid-structure interaction, specifically, a coupled hyperbolic second-order problem, formulated in terms of the displacement of the structure and the fluid pressure.

Discrete stability analysis of the mollification method for numerical differentiation
Computers & Mathematics with Applications, 1990 A numerical differentiation procedure is proposed based on discrete mollification. Numerical stability is proved and error analysis of the numerical procedure is presented. An example is considered of a function identification problem in transient heat conduction.

Numerical identification of diffusivity coefficient and initial condition by discrete mollification
Computers & Mathematics with Applications, 1995 Two inverse problems for parabolic equations are formulated in which the coefficient \(a(x, t)\) and the initial condition \(u(x, 0)\) have to be identified simultaneously under the assumption that the measurements are given at the active boundary only.

Efficient parameter estimation in a macroscopic traffic flow model by discrete mollification
Transportmetrica A: Transport Science, 2015 Our concern is the numerical identification of traffic flow parameters in a macroscopic one-dimensional model whose governing equation is strongly degenerate parabolic. The unknown parameters determine the flux and the diffusion terms. The parameters are estimated by repeatedly solving the corresponding direct problem under variation of the parameter ...

Automatic numerical differentiation by discrete mollification
Computers & Mathematics with Applications, 1987 The author gives a method to estimate the derivative based on attempting to reconstruct a modified version of the derivative. This approach was first introduced by \textit{V. V. Vasin} [Zh. Vychisl. Mat. Mat. Fiz. 13, 1383-1389 (1973; Zbl 0306.65007)].

IMA Journal of Numerical Analysis, 2012 Discrete mollification is a versatile convolution based filtering procedure for the regularization of ill-posed problems and the stabilization of explicit schemes for the solution of partial differential equations. While introducing one- and two-dimensional discrete mollification formulae, the authors propose two schemes, which are based on direction ...
