Diffusion Coefficients for Resonant Relativistic Wave‐Particle Interactions Using the PIRAN Code

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Quasilinear diffusion coefficients can be used to model the response of charged particles to resonant wave‐particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential users, because of the expense in time spent developing the code.

Quantum entanglement on black hole horizons in string theory and holography

Journal of High Energy Physics
We compute the exact one-loop partition function of ℤ N orbifolds of Euclidean BTZ black hole with the aim to compute the entanglement entropy of the black hole horizon in string theory as a function of the mass and spin of the black hole and the AdS3 ...

Three‐Dimensional Forward Modeling of Vector and Tensor Gravitational Fields Using the FFT‐Accelerated Finite‐Difference Scheme

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Three‐dimensional gravity forward modeling with conventional numerical methods requires solving large‐scale linear system using direct matrix inversion or iterative solvers, incurring substantial computational costs that critically limit large‐scale three‐dimensional inversions.

The Climate Modeling Alliance Atmosphere Dynamical Core: Concepts, Numerics, and Scaling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This paper presents the dynamical core of the Climate Modeling Alliance (CliMA) atmosphere model, designed for efficient simulation of a wide range of atmospheric flows across scales. The core uses the nonhydrostatic equations of motion for a deep atmosphere, discretized with a hybrid approach that combines a spectral element method (SEM) in ...

Harnessing Satellite Constellations as Signals of Opportunity for an Enhanced Specification of the Satellite Drag Environment in the Critical LEO Regime

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Enhancing the accuracy of orbit predictions for low‐Earth orbit (LEO) satellites and debris is vitally important for satellite owner/operators dedicated to ensuring the safety and sustainability of the LEO environment. Presently, the largest source of error in orbit predictions stems from uncertainties in the estimation of thermospheric mass ...

A Boundary Element Model for Assessing Large‐Scale Pressurization in Faulted Geological Storage Systems

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Assessing large‐scale pressurization at the regional scale—a possible outcome of large subsurface storage applications such as wastewater injection and geological carbon sequestration—presents significant computational challenges. These challenges are particularly pronounced when accounting for complex geologic structures with multiple ...

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

Journal of Time Series Analysis, Volume 47, Issue 2, Page 304-320, March 2026.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.
