Little devils of Neotropical forests: A first molecular phylogeny of stygnid harvestmen with UCE‐museomics and a gigamatrix approach (Arachnida, Opiliones, Stygnidae)

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First family‐wide phylogenomic framework of Stygnidae using UCE‐museomics and a gigamatrix approach establishes a novel three‐subfamily classification, erecting the new subfamily Auraninae subfam. nov. Signatures of severe incomplete lineage sorting and short deep internodes suggest a rapid early‐burst Neotropical radiation, driving phylogenetic ...

Solitary wave solutions of nonlinear integro-partial differential equations of \((2 + 1)\)-dimensional and its models

International Journal of Differential Equations, 2022
The findings indicate an application of a new method of expansion of the forms Z′/Z and 1/Z to determine the solutions for wave of the solitary nature in the 2+1-dimensional modified form for nonlinear integro-partial differential equations. By using this strategy, we acquired solutions of wave which has a solitary nature that have been solved for ...

Numerical Modeling of Inertial Particles in Three‐Dimensional Fluid Flow

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The motion of inertial particles in a fluid is modeled by the Maxey–Riley–Gatignol equation (MaRGE). The MaRGE contains an integral term that arises due to the viscous diffusion of vorticity in the fluid around the particle. Because it makes MaRGE difficult to solve numerically, the integral term is often neglected or approximated, despite its

An Analytical and Approximate Solution for Nonlinear Volterra Partial Integro-Differential Equations with a Weakly Singular Kernel Using the Fractional Differential Transform Method

International Journal of Differential Equations, 2018
An analytical-approximate method is proposed for a type of nonlinear Volterra partial integro-differential equations with a weakly singular kernel. This method is based on the fractional differential transform method (FDTM).

Modification of the Differential Transform Method With Search Direction Along the Spatial Axis

International Journal of Differential Equations
This paper presents a modification of the Differential Transform Method (ModDTM) formulated so that the search direction of the solution is along a spatial axis (x). It is shown that the method is applicable to a wide spectrum of 1+1 partial differential
