  2. Spatiotemporal gene expression - Wikipedia

    en.wikipedia.org/wiki/Spatiotemporal_gene_expression

    Spatiotemporal variation plays a key role in generating the diversity of cell types found in developed organisms; since the identity of a cell is specified by the collection of genes actively expressed within that cell, if gene expression was uniform spatially and temporally, there could be at most one kind of cell.

  3. Spatiotemporal pattern - Wikipedia

    en.wikipedia.org/wiki/Spatiotemporal_pattern

    The distinction between spatial and spatio-temporal patterns in nature is not clear-cut because a static, invariable pattern will never occur in the strict sense. Even rock formations will slowly change on a time-scale of tens of millions of years, therefore the distinction lies in the time scale of change in relation to human experience .

  4. Spectro-temporal receptive field - Wikipedia

    en.wikipedia.org/wiki/Spectro-temporal_receptive...

    The spectro-temporal receptive field or spatio-temporal receptive field (STRF) of a neuron represents which types of stimuli excite or inhibit that neuron. [1] " Spectro-temporal" refers most commonly to audition, where the neuron's response depends on frequency versus time, while "spatio-temporal" refers to vision, where the neuron's response depends on spatial location versus time.

  5. Spatial analysis - Wikipedia

    en.wikipedia.org/wiki/Spatial_analysis

    Spatial dependency is the co-variation of properties within geographic space: characteristics at proximal locations appear to be correlated, either positively or negatively. [33] Spatial dependency leads to the spatial autocorrelation problem in statistics since, like temporal autocorrelation, this violates standard statistical techniques that ...

  6. Spatiotemporal database - Wikipedia

    en.wikipedia.org/wiki/Spatiotemporal_database

    A spatiotemporal database embodies spatial, temporal, and spatiotemporal database concepts, and captures spatial and temporal aspects of data and deals with: Geometry changing over time and/or Location of objects moving over invariant geometry (known variously as moving objects databases [ 1 ] or real-time locating systems ).

  7. Spatial–temporal reasoning - Wikipedia

    en.wikipedia.org/wiki/Spatial–temporal_reasoning

    Spatial–temporal reasoning is an area of artificial intelligence that draws from the fields of computer science, cognitive science, and cognitive psychology. The theoretic goal—on the cognitive side—involves representing and reasoning spatial-temporal knowledge in mind.

  9. Temporal resolution - Wikipedia

    en.wikipedia.org/wiki/Temporal_resolution

    Often there is a trade-off between the temporal resolution of a measurement and its spatial resolution, due to Heisenberg's uncertainty principle.In some contexts, such as particle physics, this trade-off can be attributed to the finite speed of light and the fact that it takes a certain period of time for the photons carrying information to reach the observer.
