Knowledge gap on the spatial structure of soil nitrogen mineralization variability—A systematic review

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Soil nitrogen (N) mineralization governs plant‐available N from soil organic matter and microbial turnover, and is typically estimated as potentially mineralizable nitrogen (PMN) via anaerobic incubations or as N0 and mineralization rate (k) via long‐term aerobic incubations.

The Correct Kriging Variance Estimated by Bootstrapping

open access: yes
The classic Kriging variance formula is widely used in geostatistics and in the design and analysis of computer experiments.This paper proves that this formula is wrong.Furthermore, it shows that the formula underestimates the Kriging variance in ...

Information Diffusion Interpolation Model Based on the PSO-CV Algorithm and Its Application on Source Regions of the Yellow River

open access: yesRenmin Zhujiang, 2021
The spatial interpolation based on the limited observation data of precipitation stations is an effective means to explore the spatial characteristics of precipitation.This paper briefly introduces a spatial interpolation model based on the information ...

Bayesian Implementation of the Factor‐Analytic Mixed Model and Application to Embeddings

open access: yesStat, Volume 15, Issue 3, September 2026.
ABSTRACT Mixed models and neural networks each offer complementary frameworks for prediction. Theoretically grounded in inference, mixed models can unveil latent variance structure notably with the factor‐analytic approach. In this article, we propose to bridge the gap between the two frameworks, leveraging embedding data from a neural network encoder ...

CESAR: A Convolutional Echo State AutoencodeR for High‐Resolution Wind Forecasting

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract An accurate and timely assessment of wind speed and energy output allows an efficient planning and management of this resource on the power grid. Wind energy, especially at high resolution, calls for the development of nonlinear statistical models able to capture complex dependencies in space and time. This work introduces a Convolutional Echo

Disjunctive kriging for environmental management

open access: yes, 1996
Land managers, legislators and law enforcement agencies must often make decisions based on critical thresholds and using estimates that are subject to error. Disjunctive kriging enables this error to be converted to an estimated probability that the true

A Vast Valley Network Beneath the Greenland Ice Sheet

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

Late‐Onset Rheumatoid Arthritis and Air Pollution in a Multiethnic Cohort

open access: yesArthritis &Rheumatology, Volume 78, Issue 7, Page 1425-1436, July 2026.
Objective To evaluate the effects of ambient air pollution on rheumatoid arthritis (RA) incidence in a racially and ethnically diverse population. Methods This analysis included 42,152 California Multiethnic Cohort participants, aged ≥65 years (>70% African American and Latino adults) who were enrolled in the Fee For Service component of Medicare (2001–
