The visual cortex as a spatial frequency analyser

Vision Research, 1973
Abstract Unitary responses to sinusoidal gratings either moving or alternating in phase have been investigated in the optic tract, lateral geniculate body and visual cortex of the cat as a function of the spatial frequency, position of the grating with respect to the cell receptive field and grating contrast.

Spatial Analyses

2019
Many earth systems phenomena take place over a region continuously by time; hence, the variation is of the spatio-temporal type. The spatial evolvement of the events can be sampled generally at a set of irregular sites or particularly at regular mesh grid nodes as already explained in the previous chapter.

Spatial Transcriptomic Analyses of Spermatogenesis

Measuring mRNA abundance at the level of the whole transcriptome has become an indispensable tool for the investigation of fundamental biological processes in higher eukaryotes. However, traditional transcriptomic methods are destructive and ignore the three-dimensional organization of cells within tissues and organs.

Health and GIS: Toward Spatial Statistical Analyses

Journal of Medical Systems, 2004
This study examined the extent to which health studies, mostly in public health and epidemiology, used geographical information systems (GIS). We identified a wide range of tools they used-ranging from geocoding through simple buffer/overlay functions to spatial query functions.

Leontief's spatial economic analyses

Structural Change and Economic Dynamics, 1995
Abstract This paper provides a brief review of Wassily W. Leontief's major contributions in intranational and multiregional input-output analyses. In addition, the importance of these contributions to today's accounting practices, data collection, and computer technologies are emphasized.

The GIS Platform and the Spatial Analyses

2019
Spatial analyses, carried out using a GIS (Geographic Information System) platform, investigated the relationship between different environments (from the coast to the highlands) and human settlement and mobility strategies, in a diachronic perspective.

Spatial and non-spatial analyses of insect counts in bulk-stored barley

Bulletin of Entomological Research, 2009
AbstractStored grain insect species in bulk-stored barley were sampled during 15 consecutive weeks in two ways: direct sampling based on grain trier samples and indirect sampling based on probe trap captures. A total number of 22 insect taxa were found; this study focused on the six most abundant species and their natural enemies.

Analysing the Usage of Spatial Prepositions in Short Messages

2014
Spatial prepositions such as in, on and near are important to describe where things are located in relation to other geographic features. Location-based services (LBS) usually disregard such spatial prepositions. Their automatic detection and interpretation is challenging, because prepositions are quite often used in non-spatial context (e.g., “in the ...

Archéopédologie et analyses spatiales

2016
L’approche archéopédologique developpée sur l’emprise des parcellaires gallo-romains conservés sous forêt permet d’aborder la gestion des terroirs et les modalités d’exploitation des espaces agraires. Un echantillonnage spatial de la couverture pédologique présente au sein des parcelles a été réalisé.
