Driving SDG15: The Role of HEIs in Biodiversity Conservation Through Digitalization and Reporting

Sustainable Development, Volume 33, Issue 5, Page 6985-7004, October 2025.
ABSTRACT Education, research, and public engagement are key strategies guiding European higher education institutions (HEIs) in advancing the United Nations Sustainable Development Goals (SDGs). Through stakeholder, legitimacy, and resource‐based view theories, this study examines the contributions of HEIs to saving Life on Land (SDG15), focusing on ...

The Harnack estimate for the Ricci flow

Journal of Differential Geometry, 1993
The author proves the following theorem: Let \(g_{ij}\) be a complete solution with bounded curvature to the Ricci flow \({\partial g_{ij}\over \partial t}= -2 R_{ij}\) on a manifold \(M\) in some time interval \(0< t< T\) and suppose \(g_{ij}\) has a weakly positive curvature operator, so that \(R_{ijkl} U_{ij} U_{kl}\geq 0\) for every two-form \(U_ ...

Carbon Isotope and Abundance Systematics Reveal an Insignificant Crustal Sink of Mantle‐Derived CO2 in On‐Land Rift Zone Geothermal Systems

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Rift zones, both on land and submarine, are key pathways for mantle‐derived CO2 degassing to the Earth's surface. Fixation of CO2 as carbonates plays a critical role in regulating these emissions. This study examines carbon abundance and isotope compositions in hydrothermal fluids, altered rocks, and carbonates from geothermal systems in both ...

Scaling of Ion Outflow Speed and Ion Bulk Heating in Lobe Reconnection and Their Relations to Shear Flow

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Magnetic reconnection at the high‐latitude magnetopause is accompanied by velocity shear due to the tailward flow of the magnetosheath. This study investigates 24 high‐latitude magnetopause reconnection events observed by the Cluster satellites and examines how ion outflow speed and ion bulk heating depend on the upstream Alfvénic parameters ...
