Analytical treatment of system of KdV equations by Homotopy Perturbation Method (HPM) and Homotopy Analysis Method (HAM) [PDF]

Computational Ecology and Software, 2014
In this article the Homotopy Perturbation Method (HPM) and Homotopy Analysis Method (HAM) are applied to obtain analytic approximate solution to three system of nonlinear wave equations, namely two component evolutionary system of a homogeneous KdV ...

Flushing of Subsurface Soil Nitrate as the Primary Cause of Increased Stream Nitrate During Storm Events

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The export flux of nitrate from forested catchments via streams typically increases during storms due to simultaneous increases in the nitrate concentration and flow rate. Potential nitrate sources responsible for this increase include rainwater and soil nitrate.

Chaotic dynamics and soliton structures of the (3+1)-dimensional Hirota model with application to secure image encryption

Boundary Value Problems
This work explores complex dynamical analysis of a new (3+1)-dimensional Hirota model, which has not yet studied in the literature. The wave transformation approach is utilized and the proposed model is reduced into system of ordinary differential ...

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.

Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Lysine Biosynthesis Defines a Metabolic Checkpoint for Gibberellin‐Mediated Growth in Arabidopsis thaliana

Plant, Cell &Environment, Volume 49, Issue 8, Page 5343-5357, August 2026.
ABSTRACT Lysine represents a metabolic hub linking mitochondrial energy status with amino acid catabolism, yet its role in coordinating plant growth and development remains poorly characterised. The dapat mutant, which is deficient in L,L‐diaminopimelate aminotransferase (DAPAT), exhibits severe growth inhibition associated with broad metabolic ...

Phycobilisomes: modular light‐harvesting systems of cyanobacteria and red algae

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Phycobilisomes (PBSs) are supramolecular pigment–protein complexes that function as the principal light‐harvesting antennae in cyanobacteria, red algae (Rhodophyta), and glaucophytes, and to a lesser extent in cryptophytes. Because the intrinsic chlorophyll‐based antennae of the photosystems absorb poorly in the green region of the spectrum ...
