Spatiotemporal wavelet analysis for functional MRI [PDF]

NeuroImage, 2004
Characterizing the spatiotemporal behavior of the BOLD signal in functional Magnetic Resonance Imaging (fMRI) is a central issue in understanding brain function. While the nature of functional activation clusters is fundamentally heterogeneous, many current analysis approaches use spatially invariant models that can degrade anatomic boundaries and ...

Analysis of spatiotemporal data [PDF]

, 2021
Στην παρούσα διδακτορική διατριβή μελετάται το πρόβλημα της ανάλυσης χωροχρονικών δεδομένων. Τα χωροχρονικά δεδομένα είναι τα δεδομένα τα οποία σχετίζονται τόσο μετο χώρο όσο και με το χρόνο. Η ανάλυση χωροχρονικών δεδομένων είναι η διαδικασία εύρεσης προτύπων και η εξαγωγή γνώσης από τα χωροχρονικά δεδομένα.

Spatiotemporal Analysis of Developing Brain Networks [PDF]

Frontiers in Neuroinformatics, 2018
Recent advances in MRI have made it easier to collect data for studying human structural and functional connectivity networks. Computational methods can reveal complex spatiotemporal dynamics of the human developing brain. In this paper, we propose a Developmental Meta-network Decomposition (DMD) method to decompose a series of developmental networks ...

Temporal and Spatial Analysis Techniques as Potential Tools for Combating the HIV Epidemic among Young Brazilian Amazonian People: An Ecological Study

Tropical Medicine and Infectious Disease, 2022
Background: The main goal of this study was to analyze the HIV epidemic temporally and spatially among young people living in Pará, Brazil, from 2007 to 2018. Methods: For the temporal analysis, we employed an integrated autoregression of moving averages

Spatiotemporal correlations of handset-based service usages [PDF]

, 2012
We study spatiotemporal correlations and temporal diversities of handset-based service usages by analyzing a dataset that includes detailed information about locations and service usages of 124 users over 16 months.

cytoNet: Spatiotemporal network analysis of cell communities [PDF]

PLOS Computational Biology, 2017
We introduce cytoNet, a cloud-based tool to characterize cell populations from microscopy images. cytoNet quantifies spatial topology and functional relationships in cell communities using principles of network science. Capturing multicellular dynamics through graph features, cytoNet also evaluates the effect of cell-cell ...

Dynamic multiscale spatiotemporal models for Poisson data [PDF]

, 2017
We propose a new class of dynamic multiscale models for Poisson spatiotemporal processes. Specifically, we use a multiscale spatial Poisson factorization to decompose the Poisson process at each time point into spatiotemporal multiscale coefficients.
