Analysing Spatial Intrapersonal Variability of Road Users Using Point-to-Point Sensor Data [PDF]
, 2023 The availability of newly emerging forms of data in recent years has provided new opportunities to study spatial intrapersonal variability, namely the variability in an individual’s destination and route choices from day to day.

Vegetation structure determines the spatial variability of soil biodiversity across biomes
Scientific Reports, 2020 The factors controlling the spatial variability of soil biodiversity remain largely undetermined. We conducted a global field survey to evaluate how and why the within-site spatial variability of soil biodiversity (i.e. richness and community composition)

How does dynamical spatial variability impact 234Th-derived estimates of organic export? [PDF]
, 2012 In this study we first evaluate the small-scale spatial variability of particulate export, using a set of synoptic thorium-234 activity observations sampled within a one-degree radius.

Spatial and temporal variability of iodine in aerosol [PDF]
Journal of Geophysical Research: Atmospheres, 2020 AbstractIn this work, we describe the compilation and homogenization of an extensive data set of aerosol iodine field observations in the period between 1963 and 2018 and we discuss its spatial and temporal dependences by comparison with CAM‐Chem model simulations. A close to linear relationship between soluble and total iodine in aerosol is found (∼80%

Satisfiability of a Spatial Logic with Tree Variables [PDF]
, 2007 We investigate in this paper the spatial logic TQL for querying semi-structured data, represented as unranked ordered trees over an infinite alphabet. This logic consists of usual Boolean connectives, spatial connectives (derived from the constructors of a tree algebra), tree variables and a fixpoint operator for recursion.

Dietary selenium intake among Ethiopian children in areas known for selenium spatial variability [PDF]
, 2023 Introduction: There is spatial variability of selenium (Se) in soil and crops in Ethiopia. We assessed the Se content of food items, breast milk, and urine among infants in Ethiopia from two areas with contrasting Se concentrations in soils.
