Mean values of cubic and quartic Dirichlet Characters [PDF]
, 2020 We evaluate the average of cubic and quartic Dirichlet character sums with the modulus going up to a size comparable to the length of the individual sums.

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.A research gap exists concerning how different chaotic mappings influence the applicability of metaheuristic algorithms, along with inherent limitations of the traditional artificial hummingbird algorithm (AHA). Specifically, blind spots in population coverage and vulnerability to local optima stemming from random initialization.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.To overcome the difficulties of empirical analogy, physical testing, and conventional finite element (FE) simulation in extracting joint stiffness for beam models of shield tunnel linings, we proposed an isogeometric (IG) Reissner–Mindlin (RM) shell model with a narrow layer.

, 2016 In 2005 Blache studied certain generalized Gauss sums and established an analogue for them of Stickelberger\u27s congruence for classical Gauss sums over finite fields. We improve on Blache\u27s work in two ways: (i) simplify Blache\u27s proof and give a

Advances in Meteorology, Volume 2026, Issue 1, 2026.To address the issue of difficulty in calculating the formula for rainstorm intensity due to insufficient data duration, taking Xunxian as an example, 40 years of minute‐level precipitation data from six surrounding meteorological stations were utilized. Five mathematical and physical methods were applied to explore the extended interpolation of minute‐

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.On‐ramp merging is a common expressway maneuver for connected and automated vehicles (CAVs), where trajectory planning and tracking control are central to avoiding collisions. However, existing studies rarely optimize the selection of merge start and end points and give limited attention to constraints from acceleration‐lane length. This study proposes

Radial Basis Function Collocation With L‐BFGS Optimization for Higher Order Initial Value Problems
Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.This paper describes a radial basis function collocation method that uses limited‐memory Broyden–Fletcher–Goldfarb–Shanno optimization to solve one‐dimensional ordinary differential initial value problems. Numerical tests include first‐order problems and manufactured fourth‐, sixth‐, and eighth‐order problems.

Explicit formulas for Hecke Gauss sums in quadratic number fields
, 2010 We derive an explicit formula for Hecke Gauss sums of quadratic number fields. As an immediate consequence we obtain a quadratic reciprocity law in quadratic number fields which generalizes the classical one given by Hecke. The proofs use, apart from the
