Hamiltonian Structures of the Multi-Boson KP Hierarchies, Abelianization and Lattice Formulation

, 1994
We present a new form of the multi-boson reduction of KP hierarchy with Lax operator written in terms of boson fields abelianizing the second Hamiltonian structure.

Extensions of the N=2 Supersymmetric a=-2 Boussinesq Hierarchy [PDF]

, 1997
We present two different Lax operators for a manifestly N=2 supersymmetric extension of "a=-2" Boussinesq hierarchy . The first is the supersymmetric generalization of the Lax operator of the Modified KdV equation. The second is the generalization of the

Miura type transformations and homogeneous spaces [PDF]

Journal of Physics A: Mathematical and General, 2005
We relate Miura type transformations (MTs) over an evolution system to its zero-curvature representations with values in Lie algebras g. We prove that certain homogeneous spaces of g produce MTs and show how to distinguish these spaces. For a scalar translation-invariant evolution equation this allows to classify all MTs in terms of homogeneous spaces ...

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

Advanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

Advanced Intelligent Systems, EarlyView.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Multicomponent bi-superHamiltonian KdV systems

, 2001
It is shown that a new class of classical multicomponent super KdV equations is bi-superHamiltonian by extending the method for the verification of graded Jacobi identity.

Regular solution and lattice Miura transformation of bigraded Toda hierarchy [PDF]

Chinese Annals of Mathematics, Series B, 2013
In this paper, we give finite dimensional exponential solutions of the bigraded Toda Hierarchy(BTH). As an specific example of exponential solutions of the BTH, we consider a regular solution for the $(1,2)$-BTH with $3\times 3$-sized Lax matrix, and discuss some geometric structure of the solution from which the difference between $(1,2)$-BTH and ...

A Multimode Soft Robot Based on a Single Braided Tube

Advanced Intelligent Systems, EarlyView.
This study introduces a novel soft multimode robot based on a single braided tube directly formed and actuated by SMA wires with distinct initial configurations. By combining contraction, elongation, and bending deformations, the robot achieves straight crawling, turning, inchworm crawling, and rolling without additional actuators.

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, EarlyView.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Free Field Realization of $N=2$ Super $W_{3}$ Algebra

, 1993
We study the quantum $N=2$ super-$W_{3}$ algebra using the free field realization, which is obtained from the supersymmetric Miura transformation associated with the Lie superalgebra $A(2|1)$.
