EXACT SOLUTIONS FOR DIFFERENTIAL-DIFFERENCE EQUATIONS BY BÄCKLUND TRANSFORMATION OF RICCATI EQUATION [PDF]

, 2010
Based on a Bäcklund transformation of the Riccati equation and its known soliton solutions, we obtain in this paper some exact traveling-wave solutions, including triangle function solutions and hyperbolic function solutions, of a hybrid lattice equation.

Hypervalent Iodine‐Mediated Synthesis of Sulfones Using Organozinc Pivalates and Sulfinate Salts

European Journal of Organic Chemistry, Volume 29, Issue 13, 13 April 2026.
A general protocol for sulfone synthesis via sulfonyl‐containing hypervalent iodine reagents and organozinc pivalates is described. The method is practical, provides a broad scope of sulfone in moderate to high yield. bicyclo[1.1.1]pentane‐sulfones are also disclosed and a one‐pot synthesis of Diels–Alder adduct is presented. Sulfones are key motifs in

Suprathermal Soliton Solutions to Nonlinear Schrödinger Equation

Contributions to Plasma Physics, Volume 66, Issue 3, March 2026.
ABSTRACT Maxwell distributions are very difficult to find in the low‐pressure environment far away the Earth atmosphere, permeated by high temperatures, various types of radiation, highly energetic particles, space debris, and subjected to microgravity, presenting crucial challenges for spacecraft design and operations, and affecting astronaut's health.

Global diversification of coastal Cafius rove beetles (Coleoptera: Staphylinidae) driven by ocean currents since the early Miocene

Cladistics, Volume 42, Issue 1, Page 79-94, February 2026.
Abstract As our understanding of abiotic factors continues to grow, along with insights into the biological traits of organisms, so too does the sophistication of studies exploring global diversification and spatio‐temporal distribution patterns. The global distribution of coastal Cafius rove beetles, combined with the endemic distribution patterns ...

Lax pairs and Bäcklund transformations for a new (3+1)-dimensional integrable equation utilizing symbolic computation

Ain Shams Engineering Journal
This article discusses a new integrable wave equation in (3+1)-dimensions that describes shallow water waves. The auto–Bäcklund and Cole-Hopf transformations are constructed by means of the homogeneous balance approach, which results in numerous new ...

Some symmetries, similarity solutions and various conservation laws of a type of dispersive water waves

Advances in Difference Equations, 2019
We investigate the point symmetries, Lie–Bäcklund symmetries for a type of dispersive water waves. We obtain some Lie transformation groups, various group-invariant solutions, and some similarity solutions.

Thiophenderivate als vielseitige Vorstufen für die Synthese von (Hetero)aromaten und Naturstoffen

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Verborgen, aber leistungsstark: Thiophene und ihre gesättigten Analoga haben sich als vielseitige C4‐Bausteine erwiesen, die sich effektiv in der Naturstoffsynthese sowie beim Aufbau funktionalisierter (Hetero)aromaten einsetzen lassen. Dieser Minireview soll einen Überblick über Strategien zur Anwendung dieser schwefelhaltigen heterozyklischen ...

From quantum Bäcklund transforms to topological quantum field theory [PDF]

, 2016
We derive the quantum analogue of a Bäcklund transformation for the quantized Ablowitz–Ladik chain, a space discretization of the nonlinear Schrödinger equation. The quantization of the Ablowitz–Ladik chain leads to the q-boson model.

Similarity reduction, Bäcklund transformation and solitary waves for a generalized shallow water wave equation with the variable coefficients

Ain Shams Engineering Journal
In this paper, we have studied the generalized shallow water wave equation with variable coefficients which represent different wave phenomena as tidal waves, irrigation flows, tsunamis, storm surges, and atmospheric waves by using two different ...

Momentum conserving defects in affine Toda field theories

Journal of High Energy Physics, 2017
Type II integrable defects with more than one degree of freedom at the defect are investigated. A condition on the form of the Lagrangian for such defects is found which ensures the existence of a conserved momentum in the presence of the defect.
