Advances in Modal Regression: From Theoretical Foundations to Practical Implementations
WIREs Computational Statistics, Volume 18, Issue 1, March 2026.Modal regression. ABSTRACT Modal regression has emerged as a powerful alternative to traditional mean and quantile regression by focusing on estimating the conditional mode rather than the conditional mean or quantiles. This approach offers robustness to outliers and skewed distributions while providing more informative prediction intervals for ...

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

Bayesian Approach to Ionospheric Elementary Current Systems Using Differentiable Basis Functions
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Spherical elementary current systems (SECS) have become a widely used tool to model vector fields on spherical surfaces in ionospheric data analysis. The systems were originally formulated using point sources for the divergence and curl of the fields. In this paper we present a flexible alternative formulation, showing how continuous functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Understanding fault‐zone permeability is crucial in model‐based assessment of fluid migration, earthquake nucleation, and hydrothermal or hydrocarbon systems. Vertical seismic profiling (VSP) often captures Stoneley (tube) waves generated by fluid‐formation coupling in and around a borehole.

Investigating the Effect of Internal Waves on Vertical Ice Melting Rates
Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract Polar ice sheets are losing mass as a result of ocean‐driven melting processes and thus affecting global climate and sea level. Understanding the relevant dynamics and interactions at the ice‐ocean interface is crucial to developing more accurate sea‐level rise projections, but key ocean processes have not yet been considered in detail.

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 ...

Journal of Time Series Analysis, Volume 47, Issue 2, Page 279-303, March 2026.This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

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.

Under salt stress, quinoa stomatal guard cells control transpiration in an ABA‐primed manner
New Phytologist, Volume 249, Issue 5, Page 2372-2385, March 2026.Summary Stomatal guard cells, located at the interface between the leaf and the atmosphere, play a key role in transpiration control and photosynthetic CO2 uptake. Halophytes like Chenopodium quinoa tolerate high soil salinity, but the mechanisms governing guard cell responses to salinity stress in relation to the associated epidermal bladder cells ...
