A kind of improved bivariate even order Bernoulli-type multiquadric quasi-interpolation operator and its application in two-dimensional coupled Burgers’ equations

Boundary Value Problems
Multiquadric quasi-interpolation is an efficient high-dimensional approximation algorithm. It can directly obtain the approximation term and its derivatives without solving any large-scale linear equations.

The Derivation of a Multiquadric Variant Solver for the Three-Dimensional Heston-Hull-White PDE

Axioms
The Heston-Hull-White (HHW) model is a generalization of the classical Heston approach that incorporates stochastic interest rates, making it a more accurate representation of financial markets.

α$$ \alpha $$‐KIDS: A Novel Feature Evaluation in the Ultrahigh‐Dimensional Right‐Censored Setting, With Application to Head and Neck Cancer

Statistics in Medicine, Volume 44, Issue 15-17, July 2025.
ABSTRACT Recent advances in sequencing technologies have allowed the collection of massive genome‐wide information that substantially enhances the diagnosis and prognosis of head and neck cancer. Identifying predictive markers for survival time is crucial for devising prognostic systems and learning the underlying molecular drivers of the cancer course.

A stabilized radial basis-finite difference (RBF-FD) method with hybrid kernels

, 2018
Recent developments have made it possible to overcome grid-based limitations of finite difference (FD) methods by adopting the kernel-based meshless framework using radial basis functions (RBFs). Such an approach provides a meshless implementation and is

3D Model of the Shallow Crustal Density Distribution of the Krafla Volcanic System in Iceland

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Krafla volcano, located in Iceland's North Volcanic Zone, has been extensively studied using static gravity surveys since 1975. This study integrates measurements acquired between 2022 and 2023 with legacy data to produce a new gravity map of the area. We produce gravity gradient maps to delineate shallow subsurface density features and invert

Numerical Solution of Heat Equation in Polar Cylindrical Coordinates by the Meshless Method of Lines

Journal of Mathematics, 2021
We propose a numerical solution to the heat equation in polar cylindrical coordinates by using the meshless method of lines approach. The space variables are discretized by multiquadric radial basis function, and time integration is performed by using ...

A Pilot Study for Water Storage and Carbon Variability in an Irrigation Pond of the Southeastern Plains, USA

JAWRA Journal of the American Water Resources Association, Volume 61, Issue 3, June 2025.
ABSTRACT Farm ponds are a common feature of agricultural landscapes for irrigation of crops. Yet small water bodies have been ignored as reservoirs and carbon balance features despite their ubiquity in the global landscape. These ponds contain surface water from precipitation and runoff, but in South Georgia, USA, groundwater supplementation is ...

Interpolating point spread function anisotropy

, 2012
Planned wide-field weak lensing surveys are expected to reduce the statistical errors on the shear field to unprecedented levels. In contrast, systematic errors like those induced by the convolution with the point spread function (PSF) will not benefit ...
