Evolutionary Patterns of the Genes Involved in the Integrity and Segregation of Chromosomes in Sawflies (Hymenoptera: Symphyta)

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study identifies and characterizes the genes encoding cohesin and condensin complexes across Symphytan superfamilies, revealing their structural and functional roles with conserved motifs in maintaining genome stability. Phylogenetic analyses indicate that SMC genes originated from ancient duplication events, with notable gene loss (e.g., CAPG2 ...

Analytical and Numerical Soliton Solutions of the Shynaray II‐A Equation Using the G′G,1G$$ \left(\frac{G^{\prime }}{G},\frac{1}{G}\right) $$‐Expansion Method and Regularization‐Based Neural Networks

Mathematical Methods in the Applied Sciences, Volume 49, Issue 9, Page 9814-9831, June 2026.
ABSTRACT Nonlinear differential equations play a fundamental role in modeling complex physical phenomena across solid‐state physics, hydrodynamics, plasma physics, nonlinear optics, and biological systems. This study focuses on the Shynaray II‐A equation, a relatively less‐explored parametric nonlinear partial differential equation that describes ...

Filamentary structures of the cosmic web and the nonlinear Schrödinger type equation [PDF]

, 2011
We show that the filamentary type structures of the cosmic web can be modeled as solitonic waves by solving the reaction diffusion system which is the hydrodynamical analogous of the nonlinear Schrödinger type equation. We find the analytical solution of

Memories of Hirota’s method: application to the reduced Maxwell–Bloch system in the early 1970s

, 2011
Who remembers ‘Hirota’s method’? In the early days of solitons, although the Korteweg–de Vries equation had been solved by the ‘inverse scattering method’ most solutions to integrable non-linear equations were found by simpler more direct methods ...

Current status of multilayer neutron interferometry with gaseous samples at J‐PARC

Journal of Applied Crystallography, Volume 59, Issue 3, Page 799-803, June 2026.
First measurements of the neutron scattering lengths of 3He and 4He using a multilayer‐type neutron interferometer at J‐PARC are reported, demonstrating the initial feasibility of the method with prospects for improved precision.Several few‐body nuclear models, such as the Argonne v18 potential including three‐nucleon forces and chiral effective field ...

The Hirota direct method

, 2020
The search for integrability of nonlinear partial diï¬erential and diï¬erenceequations includes the study on multi-soliton solutions. One of the most fa-mous method to construct multi-soliton solutions is the Hirota direct method.In this thesis, we explain this method in detail and apply it to explicit ex-amples.

Breather Wave Solutions for the (3+1)-D Generalized Shallow Water Wave Equation with Variable Coefficients

, 2023
The equation of the shallow water wave in oceanography and atmospheric science is extended to (3+1) dimensions, which is a known equation. To achieve this, an illustrative example of the VC generalized shallow water wave equation is provided to ...
