Paleoceanography and Paleoclimatology, Volume 40, Issue 4, April 2025.Abstract Throughout the Phanerozoic, the oceans repeatedly became oxygen depleted and deposited marine sediments called black shales. The mechanisms responsible for the compositional variability of black shales deposited at different times and places, however, are not yet fully understood.

From uncertainty and entropy to coherence and consciousness
Brain‐X, Volume 3, Issue 1, March 2025.This study proposes a model of consciousness based on information theory, positing contra the Integrated Information Theory (IIT) that perception arises from uncertainty minimization (negative entropy). Unlike the causal information definition of IIT, this model adopts the framework of standard information theory, emphasizing the role of quantum ...

Overlearning in marginal distribution-based ICA: analysis and solutions [PDF]
, 2003 The present paper is written as a word of caution, with users of independent component analysis (ICA) in mind, to overlearning phenomena that are often observed.\\ We consider two types of overlearning, typical to high-order statistics based ICA.

Magnetic Resonance in Medicine, Volume 93, Issue 3, Page 961-974, March 2025.Abstract Purpose To compare two blind source separation (BSS) techniques to principal component analysis and the electrocardiogram for the identification of cardiac triggers in self‐gated free‐running 5D whole‐heart MRI. To ascertain the precision and robustness of the techniques, they were compared in three different noise and contrast regimes ...

A Flexible Constrained ICA Approach for Multisubject fMRI Analysis
International Journal of Biomedical Imaging, Volume 2025, Issue 1, 2025.Large‐scale analysis of functional connectivity within intrinsic brain networks using functional magnetic resonance imaging (fMRI) data has been widely used for identifying biomarkers in various psychiatric disorders. While the emerging access to large neuroimaging datasets provides unprecedented opportunities for exploring brain functions, they also ...
