Abundance, predation, and habitat associations of lemming winter nests in northern Sweden

Ecosphere, 2022
Spatially synchronous fluctuations of animal populations have profound ecological consequences, especially in northern latitudes. Spatially coupled fluctuations are often seen in small rodent populations, albeit with local and regional variations.

Spatial variation of total column ozone on a global scale

, 2007
The spatial dependence of total column ozone varies strongly with latitude, so that homogeneous models (invariant to all rotations) are clearly unsuitable.

Geostatistics: Modelling spatial variation

, 2023
Geostatistics, which was developed originally for mining, is now widely used for prediction of soil conditions at unvisited sites and for mapping from sample survey data. The technique is based on models of spatial variation. Soil properties are treated as the outcomes of random spatially correlated processes, to which may be added fixed effects of ...

Spatial variation in attributable risks [PDF]

Spatial and Spatio-temporal Epidemiology, 2015
The attributable risk (AR) measures the contribution of a particular risk factor to a disease, and allows estimation of disease rates specific to that risk. While previous studies consider variability in ARs over demographic categories, this paper considers the extent of spatial variability in ARs estimated from multilevel data with confounders both at

FieldSimR: an R package for simulating plot data in multi-environment field trials

Frontiers in Plant Science
This paper presents a general framework for simulating plot data in multi-environment field trials with one or more traits. The framework is embedded within the R package FieldSimR, whose core function generates plot errors that capture global field ...

The effect of a stellar magnetic variation on the jet velocity [PDF]

, 2008
Stellar jets are normally constituted by chains of knots with some periodicity in their spatial distribution, corresponding to a variability of order of several years in the ejection from the protostar/disk system.

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Stereotactic Body Radiation Therapy for Pediatric, Adolescent, and Young Adult Patients With Osteosarcoma: Local Control Outcomes With Dosimetric Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.

Discrete transverse superconducting modes in nano-cylinders

, 2004
Spatial variation in the superconducting order parameter becomes significant when the system is confined at dimensions well below the typical superconducting coherence length.
