A multivariate variational objective analysis-assimilation method. Part 1: Development of the basic model [PDF]

The variational method of undetermined multipliers is used to derive a multivariate model for objective analysis. The model is intended for the assimilation of 3-D fields of rawinsonde height, temperature and wind, and mean level temperature observed by ...

Spatial analysis of cell patterning to aid genetic and phenotypic understanding of grass stomatal density: A case study in maize

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Biological processes involve complex hierarchies where composite traits result from multiple component traits. However, holistically understanding of how sets of component traits interact to underpin genotype‐to‐phenotype relationships is generally lacking.

Numerical Simulation of Post‐Yield Hysteretic Behavior of Lap‐Spliced Reinforced Concrete Bridge Pier Walls Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1356-1376, May 2026.
ABSTRACT Reinforced concrete pier walls designed before the 1970s often incorporate lap splice in potential plastic‐hinge regions. Previous experimental tests indicate that most of pier walls experienced post‐yield lap splice failure, necessitating a modeling approach that captures not only lap splice strength but also deformation capacity.

Prospective Comparison of DWI‐Derived Virtual MR Elastography and Conventional MR Elastography in Metabolic Dysfunction‐Associated Steatotic Liver Disease and Healthy Volunteers

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 996-1008, April 2026.
ABSTRACT Background Virtual MR elastography (VMRE) and MRE have been proposed for liver fibrosis staging in metabolic dysfunction‐associated steatotic liver disease (MASLD), but VMRE's diagnostic performance remains debated. Purpose To assess the inter‐visit and inter‐reader reproducibility of fat‐uncorrected and fat‐corrected diffusion‐weighted ...

Deformation and Earthquake Potential on the North America–Caribbean–Cocos Plate Boundary System in Guatemala

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In Guatemala, the Cocos, North American, and Caribbean plates interact to create a region of high seismic risk. Previous analyses of crustal faults in the country have been overly simplified, creating discrepancies between geologic and geodetic slip rate models.

Modeling Suffusion in Porous Media Using a Particle Scale Linear Decay Function

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Suffusion with migration of fine particles (fines) in pores is a common subsurface hydrological process in nature, which has significant impacts on breaching of dikes, dam failure, and hillslope instability. However, the effects of soil properties and hydrodynamic conditions on fines migration, and the physical implications of mass flow rates ...

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach

Mathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4184-4197, 30 March 2026.
ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Empirical central limit theorems for ergodic automorphisms of the torus

, 2013
Let T be an ergodic automorphism of the d-dimensional torus T^d, and f be a continuous function from T^d to R^l. On the probability space T^d equipped with the Lebesgue-Haar measure, we prove the weak convergence of the sequential empirical process of ...

A nonparametric regression cross spectrum for multivariate time series [PDF]

We consider dependence structures in multivariate time series that are characterized by deterministic trends. Results from spectral analysis for stationary processes are extended to deterministic trend functions.
