Travelling wave solutions and conservation laws for the Korteweg-de Vries-Bejamin-Bona-Mahony equation

open access: yesResults in Physics, 2018
In this work we study the Korteweg-de Vries-Benjamin-Bona-Mahony (KdV-BBM) equation, which describes the two-way propagation of waves. Using Lie symmetry method together with Jacobi elliptic function expansion and Kudryashov methods we construct its ...

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies

open access: yesAdvanced Science, EarlyView.
A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

ON INFINITE SERIES OF NONLOCAL CONSERVATION LAWS FOR PARTIAL DIFFERENTIAL EQUATIONS

open access: yesНаучный вестник МГТУ ГА, 2018
Популярное в математике понятие интегрируемости дифференциальных уравнений (и столь же разнообразно трактуемое) тесно связано с существованием симметрий и законов сохранения.

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

open access: yesAdvanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

Darboux transformation with dihedral reduction group [PDF]

open access: yes, 2014
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 ...

Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

open access: yesAdvanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Scientific bases of elementary physics courseon the example of the part «Conservation laws in mechanics»

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2017
The article is devoted to the conservation laws in mechanics. In this paper, an overview of the 3 fundamental physical laws, which are important in physics is quite huge. Conservation laws hold of all the laws of nature a special position.

A Magnetic‐Driven Self‐Rotation‐Stabilized Miniature Swimming Robot

open access: yesAdvanced Science, EarlyView.
Inspired by the stable rotational descent of seeds in nature, this study designs a magnetic‐driven self‐rotation‐stabilized miniature swimming robot (MSMSR). Based on a resonance‐driven strategy, the robot exhibits high swimming performance, offering enhanced directional swimming and improved resistance to water flow disturbances compared to existing ...

Conservation laws for perturbed solitons in optical metamaterials

open access: yesResults in Physics, 2018
The conservation laws for the dynamics of soliton propagation through optical metamaterials are derived by the aid of Lie symmetry analysis. The proposed model will be studied with two forms of nonlinearity. They are Kerr law and parabolic law. Keywords:

The Hartwick rule as a conservation law [PDF]

open access: yes
Using conservation laws, we provide a new proof of the Hartwick result, i.e. there is intergenerational equity if and only if net investment is constant.
