Episodic Gregariousness Leads to Level‐Dependent Core Habitats: A Case Study in Eastern Copperheads (Agkistrodon contortrix)
Sign Up to like & getrecommendations! Published in 2025 at "Ecology and Evolution"
DOI: 10.1002/ece3.70788
Abstract: ABSTRACT Characterizing the complex relationships between animals and their habitats is essential for effective wildlife conservation and management. Wildlife–habitat selection is influenced by multiple life‐history requirements, which act over varying spatial and temporal scales, and… read more here.

Use of Blood Oxygenation Level‐Dependent MRI to Predict Clinical Outcomes After Endovascular Revascularization in Peripheral Artery Disease
Sign Up to like & getrecommendations! Published in 2025 at "Journal of Magnetic Resonance Imaging"
DOI: 10.1002/jmri.70038
Abstract: Blood oxygenation level‐dependent (BOLD) MRI can noninvasively quantify lower extremity perfusion in peripheral artery disease (PAD) patients. However, its ability to reflect perfusion change in response to lower extremity revascularization (LER) and its prognostic value… read more here.

DOI: 10.1002/nbm.5252
Abstract: Blood oxygen level‐dependent functional magnetic resonance imaging (BOLD fMRI) arises from a physiological and physical cascade of events taking place at the level of the cortical microvasculature which constitutes a medium with complex geometry. Several… read more here.

DOI: 10.1089/brain.2017.0517
Abstract: Global signal regression is a controversial processing step for resting-state functional magnetic resonance imaging, partly because the source of the global blood oxygen level-dependent (BOLD) signal remains unclear. On the one hand, nuisance factors such… read more here.

A New Approach for Functional Connectivity via Alignment of Blood Oxygen Level-Dependent Signals
Sign Up to like & getrecommendations! Published in 2019 at "Brain connectivity"
DOI: 10.1089/brain.2018.0636
Abstract: Due to technological advances, spatially indexed objects, such as blood oxygen level-dependent time series or electroencephalography data, are commonly observed across different scientific disciplines. Such object data are typically high dimensional and therefore challenging to… read more here.
