This paper reviews the geometrical properties of non-expanding and weakly isolated horizons to derive expressions for Maxwell's scalars and calculate monopole charges, ultimately demonstrating how a non-zero spin coefficient allows electromagnetic radiation to accumulate on the horizon as a quantum excitation.
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.
This paper presents a standardized protocol for the electrodeposition and alpha-spectrometry quantification of 93% Highly Enriched Uranium thin films on platinum substrates, comparing cyclic voltammetry and bulk electrolysis to optimize the fabrication of Micro-Pocket Fission Detectors for real-time neutron flux monitoring in research reactors.
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.
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.
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.
This paper introduces the Weighted CARP-CG method, which employs column-norm-based weighting to significantly accelerate the convergence and reduce computational time of large-scale frequency-domain elastic wave modeling compared to the standard CARP-CG approach, while maintaining accuracy and utilizing an optimized storage strategy.
This study optimizes sail angles on a rotating flywheel to maximize torque for wind energy applications, revealing that optimal strategies depend on the ratio of sail speed to wind speed, the number of sails for stability, and the critical threshold where excessive speed causes deceleration.
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.
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.
