Analytical fuzzy soliton solutions of a modified space–time fractional ϕ4$$ {\phi}^4 $$ model are derived using EHFM, capturing memory effects and uncertainty. Results reveal diverse wave structures and show how fractional order and fuzziness significantly influence soliton amplitude, localization, and propagation, with heightened sensitivity near the ...

BACKLUND TRANSFORMATIONS FOR LIOUVILLE’S EQUATIONS WITH EXPONENTIAL NONLINEARITY
Background. The study of Backlund 's transformations is one of the current topics in the theory of differential equations in partial derivatives. Such transformations are used to find solutions to nonlinear differential equations, including solitonic ...

ABSTRACT Introduction Hyperglycaemia is common in intensive care unit (ICU) patients and blood glucose management practices likely vary, but there are limited contemporary data on ICU doctors' and nurses' preferences. Methods We conducted an international online survey of ICU doctors and nurses. The 16‐question survey covered respondent characteristics,

Solitons, Cnoidal Waves and Nonlinear Effects in Oceanic Shallow Water Waves
Gravity water waves in the shallow-ocean scenario described by generalized Boussinesq–Broer–Kaup–Whitham (gBBKW) equations are discussed. The residual symmetry and Bäcklund transformation associated with the gBBKW equations are systematically constructed.

Parkinson's disease (PD) is characterized by the progressive loss of dopaminergic neurons in the midbrain. Cell transplantation, which aims to replace these lost neurons, has emerged as a promising approach. Early attempts using fetal ventral mesencephalic tissue showed proof‐of‐concept, with some patients achieving long‐term motor improvement. However,

New version of Bäcklund transformations in Euclidean 3-space
In this paper, we study the Bäcklund transformations for the adjoint curve in the Euclidean 3-space. Firstly, it is obtained some essential equations of the Bäcklund transformation.

Darboux transformation with dihedral reduction group [PDF]
We construct the Darboux transformation with Dihedral reduction group for the 2-dimensional generalisation of the periodic Volterra lattice. The resulting Bäcklund transformation can be viewed as a nonevolutionary integrable differential difference ...

This study investigates a nonlinear Navier‐Stokes‐type model for elastic cylindrical vessels. Exact solutions are derived via the Bäcklund transformation and the ϕ6$$ {\phi}^6 $$‐expansion method, and dynamical behaviors are analyzed using bifurcation and chaos tools, revealing diverse wave structures and parameter‐dependent propagation characteristics.
