Mugwort Leaf Powder (<i>Artemisia argyi</i>) Alleviates Lipid Metabolism Disorders and Intestinal Health of Common Carp (<i>Cyprinus carpio</i>) Fed High-Fat Diets. [PDF]

Aquac Nutr
Mugwort leaf powder (MLP), as a typical Chinese herbal medicine containing lots of flavonoids and polysaccharides, has strong anti‐inflammatory and immune effects. However, there are relatively few studies on the use of MLP in aquatic animals fed high‐fat (HF) diets (HFDs), especially in terms of lipid metabolism and intestinal health.

A novel local Hermite radial basis function‐based differential quadrature method for solving two‐dimensional variable‐order time fractional advection–diffusion equation with Neumann boundary conditions

Numerical Methods for Partial Differential Equations, Volume 39, Issue 4, Page 2998-3019, July 2023., 2023
Abstract A novel Hermite radial basis function‐based differential quadrature (H‐RBF‐DQ) method is presented in this paper based on 2D variable order time fractional advection–diffusion equations with Neumann boundary conditions. The proposed method is designed to treat accurately for derivative boundary conditions, which considerably improve the ...

An immersed boundary vector potential‐vorticity meshless solver of the incompressible Navier–Stokes equation

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 143-175, January 2023., 2023
We present a new strong‐form meshless solver combined with the boundary condition‐enforced immersed boundary method for the numerical solution of the nonstationary, incompressible, viscous Navier–Stokes equations in their stream function‐vorticity (in 2D) and vector potential‐vorticity (in 3D) formulation.

Adaptive Numerical Method for Approximation of Traffic Flow Equations

Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022
For a long time now, traffic equations have been considered, and different modeling has been done for it. In this article, we work on the macroscopic model, especially the most famous light model. Because these models are among the stiff and shocking problems, theoretical methods do not give good answers to these problems.

A New Sinusoidal Shear Deformation Theory for Static Bending Analysis of Functionally Graded Plates Resting on Winkler–Pasternak Foundations

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
In this article, a new sinusoidal shear deformation theory was developed for static bending analysis of functionally graded plates resting on elastic foundations. The proposed theory used an undefined integral term to reduce the number of the unknown to four without any shear correction factors.
