Variable stability of preferences in spatial reasoning

Cognitive Processing, 2013
Previous studies have highlighted the existence of preferences in human spatial reasoning. If people are asked to infer a new spatial relation from a set of given spatial relations, which do not unambiguously constrain the relation that is to be inferred, people often exhibit a preference toward one particular of all possible relations (Jahn et al ...

Spatial Variability of Phosphate Adsorption Parameters

Journal of Environmental Quality, 1988
AbstractReversible phosphate (designated P) adsorption for acid soils with a narrow pH range is described with the Langmuir kinetics equation. Using a combination of two experimental desorption techniques, i.e., desorption in water and desorption in the presence of an “infinite” sink for P, respectively, the adsorption maximum (Qm) and the adsorption ...

SPATIAL VARIABILITY OF SOILS∗

Annals of the Association of American Geographers, 1979
ABSTRACT Place-to-place variation within soil units influences the study and use of soil, but is seldom formally acknowledged in soil maps and descriptions. Research on soil variation could be improved by increased coordination of experimental designs and by application of statistical methods suitable for analysis of place-to-place variation, including

Soil: Spatial Variability

2014
Spatial variability occurs at all scales—from micrometer scale (1–10 µm) relevant to microbial processes to continental scale (1000 km) relevant to the distribution of soil orders and climate change. The order of magnitude of the coefficient of variation (CV) of soil properties ranges from a few percent to greater than 100%.

Spatial variability in airborne pollen concentrations

Journal of Allergy and Clinical Immunology, 1975
Tests were conducted to determine the relationship between airborne pollen concentrations and distance. Simultaneous samples were taken in 171 tests with sets of eight rotoslide samplers spaced from one to 486 M. apart in straight lines. Use of all possible pairs gave 28 separation distances. Tests were conducted over a 2-year period in urban and rural

Analysis of Spatial Variability

1994
Once we have assembled all of the available investigation information into appropriate data structures, as discussed in Chapter 4, we are ready for the information review and analysis step. The principal objective is to obtain an in- depth appreciation of the available information that will dictate the course of the characterization process.

Environmental Mapping Based on Spatial Variability

Journal of Environmental Quality, 2002
ABSTRACTEnvironmental maps show the probable environmental states of different types of land use or development of landscape in a geographic context. Remotely sensed data are particularly efficient for environmental mapping in order to outline major environmental types.

MR imaging with spatially variable resolution

Journal of Magnetic Resonance Imaging, 1992
AbstractIn some situations it may be advantageous to produce “locally focused” magnetic resonance images that have nonuniform spatial resolution matching the expected local rate of spatial variation in the object. Because such an image has fewer pixels than a conventional image with uniformly high resolution, it can be reconstructed from fewer signals,

Spatially Variable Genes

The clinical translation of spatial transcriptomics represents cancer diagnosis and therapy based on the role and heterogeneity of cancer-associated fibroblasts (CAFs) within the tumor microenvironment (TME). Recent developments in spatial transcriptomics have enabled a detailed characterization of the spatial organization and cellular interactions ...
