A robustness-enhanced method for Riemann solver
Abstract The appearance of shock anomaly is a major unsolved problem for some low diffusion schemes when simulating the hypersonic flow. In this paper, a simple method is proposed to enhance the robustness of the low diffusion schemes to overcome the shock anomaly.

Materials and main results of the study. ABSTRACT Surfactant–polymer (SP) flooding is a promising Enhanced Oil Recovery (EOR) technique, combining improved displacement from surfactants with enhanced sweep efficiency from polymers. This study investigates two SP systems based on the biopolymer scleroxanthan (a blend of sclerotium gum and xanthan gum ...

On Cauchy problem for system of n Euler-Poisson-Darboux equations in the plane
The system of Euler-Poisson-Darboux equations is considered, the Cauchy problem is solved for the case of real n×n matrix-coefficient with one real eigenvalue or two complex conjugate eigenvalues with real part in the interval (−1/2, 1/2).

On the solution of the space-time fractional cubic nonlinear Schrödinger equation
The space–time fractional nonlinear Schrödinger equation is studied based on the modified Riemann–Liouville derivative. The fractional mapping expansion method is used to find analytical solution of this model.

Summability methods based on the Riemann Zeta function [PDF]
This paper is a study of summability methods that are based on the Riemann Zeta function. A limitation theorem is proved which gives a necessary condition for a sequence x to be zeta summable. A zeta summability matrix Zt associated with a real sequence t is introduced; a necessary and sufficient condition on the sequence t such that Zt maps l1 to l1 ...

ABSTRACT Background Residual limb hyperhidrosis (RLH) is a frequent and debilitating condition among lower‐limb prosthetic users. Although aluminium chloride is recommended first‐line for focal hyperhidrosis, its efficacy in RLH has not previously been evaluated in prospective studies.
