Multivariate techniques including principal component analysis (PCA) have been used to identify signature patterns of regional change in functional brain images. We have developed an algorithm to identify reproducible network biomarkers for the diagnosis of neurodegenerative disorders, assessment of disease progression, and objective evaluation of treatment effects in patient populations.

Temporal Ordering of Dynamic Expression Data from Detailed Spatial Expression Maps

The segmentation clock drives oscillatory gene expression across the pre-somitic mesoderm (PSM). Dynamic Notch activity is key to this process. We use imaging and computational analyses to extract temporal dynamics from spatial expression data to demonstrate that Delta ligand and Notch receptor expression oscillate in the vertebrate PSM.

Spatial Cueing

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...

We present CorrelationCalculator and Filigree, two tools for data-driven network construction and analysis of metabolomics data. CorrelationCalculator supports building a single interaction network of metabolites based on expression data, while Filigree allows building a differential network, followed by network clustering and enrichment analysis.
FAQs
Spatial autocorrelation examines whether values associated with nearby locations show dependence or patterned similarity. In Spatial Data Analysis, this helps distinguish localized clustering from broader spatial variation, which ordinary analyses may overlook when they treat observations without regard to place. In engineering, that distinction supports more informed interpretation of measurements across physical systems and complex environments.
Interpolation helps characterize spatial variation when measurements are linked to particular locations rather than considered as an unlocated list. By using available spatial information to examine values across an area, it supports interpretation of conditions between or around measured points. This broader view can assist engineering planning, environmental monitoring, and assessment of spatially distributed risks.
Ordinary analyses may miss important structure because they do not incorporate geometry, distance, or spatial relationships. Spatial Data Analysis adds those dimensions, allowing clustering, variation, and dependence to become visible in the results. That difference matters when engineering decisions depend on how measurements are arranged across a site, network, or other physical system.
Spatial queries and proximity analysis focus attention on relationships among locations, shapes, and distances. They can help determine which features are near one another or satisfy a specified spatial relationship, giving engineers a structured way to examine sites, infrastructure, networks, and environmental conditions. Their value comes from turning location relationships into analyzable evidence.
A practical workflow begins by linking measurements or features to geographic coordinates or geometry. Analysts then apply suitable operations, such as spatial queries, interpolation, proximity analysis, or spatial autocorrelation, to examine patterns and dependence. The resulting interpretation can inform modeling, resource allocation, and decisions about complex physical environments.
Spatial Data Analysis is relevant to site selection, infrastructure planning, network design, and environmental monitoring. The same approach can support assessment of flooding or ground instability by relating measurements and physical features to place. This makes location-aware evidence useful before allocating resources or selecting among engineering options.
Spatial results can improve models by revealing where conditions vary or depend on one another, rather than treating all observations as interchangeable. They also support resource allocation and evidence-based decisions in complex environments, including planning responses to environmental risks and selecting locations for infrastructure. The outcome is a stronger connection between measurements and practical engineering choices.
