A New Fractional-order Derivative-based Nonlinear Anisotropic Diffusion Model for Biomedical Imaging
Medical imaging, the process of visual representation of different organs and tissues of the human body, is employed for monitoring the normal as well as abnormal anatomy and physiology of the body. Imaging which can provide healthcare solutions ensuring

Path-Dependent Optimal Stochastic Control and Viscosity Solution of Associated Bellman Equations [PDF]
In this paper we study the optimal stochastic control problem for a path-dependent stochastic system under a recursive path-dependent cost functional, whose associated Bellman equation from dynamic programming principle is a path-dependent fully ...

On Zero-Sum Stochastic Differential Games with Jump-Diffusion Driven State: A Viscosity Solution Framework [PDF]
A zero-sum differential game with controlled jump-diffusion driven state is considered and studied by a combination of dynamic programming and viscosity solution techniques. We prove, under certain conditions, that the value of the game exists. Moreover,

Approximate solutions of the Riemann problem for a two-phase flow of immiscible liquids based on the Buckley–Leverett model [PDF]
The article proposes an approximate method based on the "vanishing viscosity" method, which ensures the smoothness of the solution without taking into account the capillary pressure.

The vanishing viscosity limit for Hamilton-Jacobi equations on Networks [PDF]
For a Hamilton-Jacobi equation defined on a network, we introduce its vanishing viscosity approximation. The elliptic equation is given on the edges and coupled with Kirchhoff-type conditions at the transition vertices. We prove that there exists exactly

Deterministic minimax impulse control in finite horizon: the viscosity solution approach [PDF]
We study here the impulse control minimax problem. We allow the cost functionals and dynamics to be unbounded and hence the value functions can possibly be unbounded. We prove that the value function of the problem is continuous.

Generalized Liouville theorem for viscosity solutions to a singular Monge-Ampère equation
In this article, we study the asymptotic behaviour at infinity for viscosity solutions to a singular Monge-Ampère equation in half space from affine geometry.

An approximation scheme for an Eikonal Equation with discontinuous coefficient [PDF]
We consider the stationary Hamilton-Jacobi equation where the dynamics can vanish at some points, the cost function is strictly positive and is allowed to be discontinuous. More precisely, we consider special class of discontinuities for which the notion

Viscosity Control of Protein Solution by Small Solutes: A Review
Viscosity of protein solution is one of the most troublesome issues for the high-concentration formulation of protein drugs. In this review, we summarize the practical methods that suppress the viscosi-ty of protein solution using small molecular ...

Optimal control problems on stratified domains
We consider a class of optimal control problems defined on a stratified domain. Namely, we assume that the statespace $\mathbb{R}^N$ admits a stratification as a disjoint union of finitely many embedded submanifolds $\mathcal{M}_i$.
