Gegenbauer Polynomial Convolution for Bi-Univalent Functions with Applications to Image Enhancement

This paper introduces a new subclass of bi-univalent functions defined via Gegenbauer polynomial convolution to derive coefficient bounds and Fekete-Szegö inequalities, which are then utilized to develop a GCEA algorithm that effectively enhances digital images by improving edge detection, preserving structural features, and increasing contrast.

A Characterization of Poset-Based Connected Manifolds and Discrete Surfaces via Cubically Normal Pseudomanifolds

This paper establishes a fundamental correspondence between the global combinatorial structure of finite regular cubical complexes and poset-based connected manifolds by proving that a complex's face poset is an n-PCM if and only if the complex itself is a cubically normal pseudomanifold, thereby providing a recognition algorithm for embedded voxel complexes.

Mathematical Modeling of Mpox with Animal Reservoir Coupling: Stability, Sensitivity, and Calibration to the 2022 US Outbreak

This paper presents a coupled SVEIQR-SEI mathematical model of Mpox transmission between animal reservoirs and humans, which demonstrates that the disease can be eliminated when the basic reproduction number is below one and, upon calibration to the 2022 US outbreak, reveals that targeted quarantine and behavioral interventions were the primary drivers of containment while highlighting the shifting influence of reservoir dynamics across different epidemic phases.

Adaptive Shrinkage Calibration of Fractional Order and Volatility in the Time-Fractional Black–Scholes Model: Evaluation under Symmetric and Asymmetric Losses

This paper proposes and numerically validates a framework for the adaptive shrinkage calibration of fractional order and volatility within a time-fractional Black–Scholes model, demonstrating through Monte Carlo simulations and empirical S&P 500 data that raw estimates often converge to classical boundaries and exhibit strong local dependence, thereby necessitating stabilization strategies that balance parameter risk with out-of-sample option pricing performance under various loss functions.

Nodal-Layer Resolution and Morse-Index Reliability in Numerical Continuation of Saturating Semilinear Elliptic Problems

This paper demonstrates that numerically converged solutions to saturating semilinear elliptic problems can still yield unreliable Morse indices due to unresolved nodal-layer effects, necessitating a two-resolution workflow that separately verifies branch fidelity and low-spectrum reliability to prevent false stability crossings.

Characterizing Complex Balanced Equilibria of Weakly Reversible Power Law Kinetic Systems via PL-TIK Decomposition

This study characterizes complex balanced equilibria in weakly reversible power law kinetic systems by introducing the PL-TIK decomposition, demonstrating that such systems with weakly reversible, incidence-independent PL-TIK decompositions are complex balanced, and validating these findings through application to Schmitz' Carbon Cycle Model.

A q-Legendre Operational Matrix Framework for the Schwarzian KdV Equation under Möbius Periodic Boundary Conditions: Spectral Accuracy and a Boundary-Induced Finite-Time Blow-up Diagnosis

This study introduces a q-Legendre spectral framework for solving the Schwarzian KdV equation under Möbius periodic boundary conditions, demonstrating spectral accuracy while diagnosing a genuine, boundary-induced finite-time blow-up mechanism distinct from numerical aliasing errors, with stability characteristics varying non-monotonically across parameter sets representing different atomic lattice structures.
