Binary Nonlinearization of Lax pairs of Kaup-Newell Soliton Hierarchy

, 1996
Kaup-Newell soliton hierarchy is derived from a kind of Lax pairs different from the original ones. Binary nonlinearization procedure corresponding to the Bargmann symmetry constraint is carried out for those Lax pairs.

Three Types Generalized Zn-Heisenberg Ferromagnet Models

Advances in Mathematical Physics, 2020
By taking values in a commutative subalgebra gln,C, we construct a new generalized Zn-Heisenberg ferromagnet model in (1+1)-dimensions. The corresponding geometrical equivalence between the generalized Zn-Heisenberg ferromagnet model and Zn-mixed ...

Initial-boundary value problems for integrable evolution equations with $3 \times 3$ Lax pairs

, 2012
We present an approach for analyzing initial-boundary value problems for integrable equations whose Lax pairs involve $3 \times 3$ matrices. Whereas initial value problems for integrable equations can be analyzed by means of the classical Inverse ...

Hamiltonian Monodromy via spectral Lax pairs

Journal of Mathematical Physics
Hamiltonian Monodromy is the simplest topological obstruction to the existence of global action-angle coordinates in a completely integrable system. We show that this property can be studied in a neighborhood of a focus-focus singularity by a spectral Lax pair approach.

Cumulative Social Disadvantage and Disease Activity in Juvenile Idiopathic Arthritis: A Childhood Arthritis and Rheumatology Research Alliance Registry Study

Arthritis Care &Research, Accepted Article.
Background Social determinants of health (SDOH) contribute to JIA disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship between cumulative social disadvantage, neighborhood disadvantage, and JIA ...

The Role of Temporal and Spectral Cues in Non-native Speech Production:

Crossings, 2023
This study investigated the role of durational and spectral cues in second language tense and lax vowel contrasts produced by non-native speakers. To test previous claims that speakers primarily rely on durational cues over spectral cues to distinguish ...

Geometry of coupled dispersionless equations with Mannheim curves

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
In this paper, a special kind of curve pair associated with each other by the linear dependency between the principal normal vector of the first curve (called Mannheim curve) and the binormal vector of the second curve (called Mannheim partner curve) is ...

The Lax pairs for the Holt system

, 1998
By using non-canonical transformation between the Holt system and the Henon-Heiles system the Lax pairs for all the integrable cases of the Holt system are constructed from the known Lax representations for the Henon-Heiles system.Comment: 7 pages ...

Promotion of DFU Wound Healing via BRG1–COL16A1 Axis in Fibroblasts

Advanced Science, EarlyView.
In normal wound healing, transcription factor BRG1 is upregulated and binds the COL16A1 promoter to enhance its expression, promoting fibroblast proliferation, migration, contraction, extracellular matrix deposition, and granulation tissue formation, thus accelerating wound closure.
