Summary: This paper investigates the perturbed Boussinesq equation in shallow water waves. The equation is significant as it describes various phenomena such as longitudinal waves in bars, long water waves, plasma waves, quantum mechanics, acoustic waves, and nonlinear optics. The study utilizes the singular manifold method and unified techniques to extract hyperbolic, trigonometric, and rational function solutions, which could provide insights into physical incidents. Additionally, the Painleve test is employed to check the integrability of the model, and two-dimensional and three-dimensional plots are used to illustrate the obtained exact solutions' physical behavior.

Summary: In this paper, the integrability of a (2+1)-dimensional generalized KdV equation is investigated. The equation passes the Painleve test by using the Weiss-Tabor-Carnevale method and Kruskal ansatz. The truncated Painleve expansion leads to the Backlund transformation and rational solutions. The bilinear Backlund transformation and Bell-polynomial-typed Backlund transformation are constructed using the Hirota bilinear method and Bell polynomials. It is proven that the (2+1)-dimensional generalized KdV equation can be regarded as an integrable model in terms of infinite conservation laws. The formula of N-soliton solutions is given and verified with the Hirota condition. The study of integrability provides theoretical guidance for solving equations and suggests the existence of exact solutions.

Summary: In this paper, a new fractal modified Benjamin-Bona-Mahony equation (MBBME) is derived to model the long wave in the fractal dispersive media of the optical illusion field based on He's fractal derivative. The semi-inverse method (SIM) is applied to develop its fractal generalized variational principle and Wang's Backlund transformation-based method is used to study the abundant exact solutions. The impact of the fractal orders on the behaviors of the different solutions is elaborated in detail.

Summary: In this paper, a (3 + 1)-dimensional generalized variable-coefficient Kadomtsev-Petviashvili (GVCKP) equation in a fluid or plasma is investigated. The Nth-order Wronskian solutions for that equation are derived and proved under certain variable-coefficient constraints, where N is a positive integer. One-, two-, and three-soliton solutions in the Wronskian for that equation are given. By means of the Pfaffianization procedure, a coupled (3 + 1)-dimensional GVCKP system is constructed from that equation. Bilinear form for that coupled system is exported. Under certain variable-coefficient constraints, those Wronski-type and Gramm-type Pfaffian solutions for that coupled system are obtained and proved with the help of the Pfaffian identities.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.

Summary: The melting line of cobalt was investigated through experimental and theoretical methods, revealing a phase transition from hexagonal close-packed structure to face-centered cubic structure at high temperatures. The melting temperatures obtained from both methods showed good agreement and can be described by a Simon-Glatzel equation. Additionally, a thermal equation of state for the face-centered cubic phase of cobalt was determined.
