This paper proposes a two-stage stochastic optimization model for synchronized two-echelon city logistics that minimizes lateness, costs, and road mode share, demonstrating a 37% reduction in expected costs compared to deterministic approaches and highlighting the superior reliability and sustainability of flexible sailing services over relocating storage units under uncertainty.
This paper resolves the fixed-component Heun problem for torus-dynamical Fuchsian systems by characterizing the specific algebraic conditions under which eliminating one component yields a genuine four-singularity Heun equation, thereby defining complex and real elimination strata without relying on restrictive assumptions on the residue at zero.
This technical note introduces a diagnostic refinement test to distinguish between grid-induced transient switches and stable, scale-separated transitions in cost-sensitive selection problems by analyzing how finite-grid breakpoints behave under mesh refinement.
This paper presents an efficient computational method combining boundary matrices, normal forms, and closed-form formulas to calculate low-degree integral magnitude homology for finite graphs, demonstrating its superior ability to distinguish nonisomorphic graph pairs compared to ordinary invariants through extensive analysis of standard families and small connected graphs.
This paper presents an accurate and stable numerical framework for solving the time-fractional Benney-Lin equation by combining a Petrov-Galerkin finite element method with quintic B-spline basis functions for spatial discretization and the Grünwald-Letnikov definition for temporal fractional derivatives, effectively capturing nonlinear wave dynamics and memory effects through comprehensive error analysis and numerical experiments.
This paper demonstrates that imposing Poisson disk sampling constraints on interpolation centers allows for the minimization of the condition number of Multiquadric Radial Basis Function matrices to a constant value independent of the number of points, thereby ensuring numerical stability through an adaptive relationship between the minimum inter-point distance, the shape parameter, and the total number of points.
The paper introduces the Lyapunov Integrability Test (LIT), a novel and efficient numerical framework that utilizes global Lyapunov exponent analysis to identify candidate integrable regimes in nonlinear dynamical systems, a method validated across diverse benchmark examples ranging from fluid flows to mechanical systems.
This paper introduces a Bipolar Linguistic Z-Number (BLZ-Number) framework that unifies positive/negative assessments with linguistic reliability to enhance Failure Mode and Effects Analysis (FMEA) through a novel integration of BLZ-BWM, BLZ-CRITIC, and MABAC methods for more expressive and reliable risk evaluation.
This paper introduces a novel approach utilizing one-generator quasi-twisted codes of index 3 and their extended versions to construct binary stabilizer quantum codes and maximal-entanglement entanglement-assisted quantum codes with improved and optimal parameters.
This paper establishes a Fourier analytic framework for supercritical Mandelbrot cascades in a random environment to prove the existence of harmonic moments, demonstrate the exponential decay of characteristic functions, and derive refined limit theorems including improved central limit theorems, Edgeworth expansions, and a renewal theorem for .
