Computationally Efficient Ranking of Sampling Locations by Redundancy in Groundwater Monitoring Networks

Groundwater Monitoring &Remediation, EarlyView.
Abstract The long‐term and frequent sampling of groundwater monitoring networks is common practice for monitoring the concentrations of constituents of potential concern (CoPC) over space and time. Sampling can be a costly and time‐intensive process that also incurs health and safety risks. A redundancy‐based ranking of candidate sampling locations can

On Spatial Point Processes With Composition‐Valued Marks

International Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

A Penalized Orthogonal Kriging Method for Selecting a Global Trend

Axioms
A kriging regression model is a popular and effective type of surrogate model in computer experiments. A significant challenge arises when the mean function of the model includes polynomial terms with unknown coefficients, leading to identifiability ...

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

International Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Spatiotemporal Dynamics of Olive Fruit Fly (Bactrocera oleae) Populations in a Mediterranean Olive‐Growing Landscape: An Eight‐Year Study From Samos Island, Greece

Journal of Applied Entomology, EarlyView.
ABSTRACT Olive fruit fly (Bactrocera oleae, Rossi) is one of the most significant pests in the Mediterranean olive groves, causing both quantitative and qualitative losses. Understanding its spatial and temporal dynamics is essential for effective and sustainable control of the pest.

Spatial variation in morphological traits of natural Haloxylon ammodendron populations on the eastern margin of the Badain Jaran Desert

Plant Biology, EarlyView.
Natural Haloxylon ammodendron populations on the eastern margin of the Badain Jaran Desert showed size‐associated differences in plant height, crown diameter, and spatial patterns among stem‐base diameter classes. These patterns describe morphological spatial variation but do not establish specific environmental drivers.

Short‐Term Effect of Air Pollutants on Sudden Unexpected Death in Infancy: A Case‐Crossover Study Based on the French National Registry

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Sudden unexpected death in infancy (SUDI) remains poorly understood, and the potential contribution of air pollution exposure is largely unexplored. Given its known impact on infant health, air pollution may influence the risk of SUDI, particularly through short‐term effects.

Model Selection for the Mean Function of Kriging Models

Journal of Education and Science
Kriging models are used in many scientific disciplines to investigate the behavior of physical systems. In the Kriging model (KM), the response of the computer simulation code (CSC) is considered to have a Gaussian process (GP). To discover variables influencing responses, choosing a selection of variables or creating a strongly reduced regression ...

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

Agricultural &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.
