‘My body was no longer a problem’: Electric mountain biking, disability, and the cultural politics of green exercise

open access: yesTransactions of the Institute of British Geographers, Volume 50, Issue 3, September 2025.
Abstract Disability is often overlooked in discussions of green exercise. Consequently, we still know little about how ableist ideologies might play out in the context of nature engagement, or the forms of pleasure that disabled people derive from participation in green spaces.

Geochemical Variations in Sedimentary Records of Oxygen‐Depleted Marine Environments in Representative Geological Periods: New Perspectives From an Independent Component Analysis

open access: yesPaleoceanography 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.

Structuring Information and Entropy: Catalyst as Information Carrier

open access: yesEntropy, 2006
Many authors tried to exploit the similarities between expressions of the statistical thermodynamics for the entropy and those of Shannon's information theory.

From uncertainty and entropy to coherence and consciousness

open access: yesBrain‐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 ...

ЭКОНОМИЧЕСКОЕ РЕГУЛИРОВАНИЕ ГРАДОСТРОИТЕЛЬНОГО РАЗВИТИЯ С УЧЁТОМ ВОЗМОЖНОСТЕЙ И ТРЕБОВАНИЙ ПРИРОДНОЙ СРЕДЫ

open access: yesSovremennye Issledovaniâ Socialʹnyh Problem, 2015
В статье приводится доказательство неспособности западной модели развития цивилизации и базирующейся на ней концепции градостроительства обеспечить выживание человечества в условиях усиливающейся биосферной деградации.

Self‐gated free‐running 5D whole‐heart MRI using blind source separation for automated cardiac motion extraction

open access: yesMagnetic 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 ...

Organism-Oriented Ontology Beyond the Anthropocene

open access: yesAnglica. An International Journal of English Studies
This article explores different approaches to the notion of the Anthropocene, understood as a state associated with the increase of entropy and the destruction of biodiversity and habitats.

A Flexible Constrained ICA Approach for Multisubject fMRI Analysis

open access: yesInternational 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 ...

Multivariate statistical “unmixing” of Indian and Pacific Ocean sediment provenance

open access: yesLimnology and Oceanography: Methods, Volume 22, Issue 11, Page 823-839, November 2024.
Abstract The geochemistry of marine sediment is a massive archive of (paleo)oceanographic information. Accessing that information requires “unmixing” the various influences on marine sediment geochemistry to understand individual sources and marine geochemical processes.
