New Exact Solutions of a Variable-Coefficient (2+1)-Dimensional Kadomtsev- Petviashvili Equation Using a Combination of Lie Symmetry Analysis and the Generalized Expansion Method

This paper derives new exact solutions for the variable-coefficient (2+1)-dimensional Kadomtsev-Petviashvili equation by combining Lie symmetry analysis to reduce the system and the Generalized Expansion Method to solve the reduced equations, thereby identifying specific coefficient classes and characterizing diverse wave structures such as solitons and periodic waves.

Numerical Investigation of Chemical Reaction and Thermal Radiation Effects on MHD Williamson Nanofluid Flow over a Hyperbolic Tangential Stretching Sheet with Joule Heating

This study numerically investigates the combined effects of Joule heating, suction, thermal radiation, and chemical reactions on the magnetohydrodynamic flow of a Williamson nanofluid over a hyperbolic tangential stretching sheet using the Runge-Kutta method to analyze how these parameters influence velocity, temperature, and concentration profiles.

Benchmarking Modular Optimization Strategies for Parameterized Quantum Circuits

This paper introduces a modular benchmarking framework that decouples quantum search-direction estimation from classical parameter-update rules to systematically evaluate the performance and cost-efficiency of various optimizers across diverse quantum workloads, including QAOA, QCNN, and VQE, under both finite-shot simulations and execution on a 156-qubit quantum processor.

Explaining the “Missing Loss” Process in Earth’s Magnetosphere

This study resolves the long-standing "missing loss" discrepancy in Earth's magnetosphere by demonstrating that time-varying background plasma density, rather than an unknown loss mechanism, modulates wave dispersion to significantly enhance electron precipitation and align theoretical flux predictions with satellite observations.

Nonlinear primary resonance of doubly curved laminated nanocomposite shells within shear deformation theory

This study presents a unified analytical framework based on shear deformation theory to investigate the geometrically nonlinear primary resonance of doubly curved laminated functionally graded nanocomposite shells on a Winkler foundation, utilizing the Galerkin method and multiple scales approach to quantify the effects of curvature, material distribution, and structural parameters on dynamic response.

Influence of Initial Gas Pressure on the Spatial Intensity Distribution of Double-Pass Amplified 69.8 nm and 72.6 nm Lasers

This study experimentally demonstrates the first double-pass amplification of 72.6 nm Ne-like Ar lasers alongside 69.8 nm lasers using a discharge-produced plasma and SiC mirror, revealing that increasing the initial gas pressure from 14 Pa to 18 Pa transforms the spatial intensity distribution from a central peak to an edge-enhanced annular profile while increasing the divergence angles of both wavelengths.
