Yang–Mills heat flow on gauged holomorphic maps [PDF]

open access: yesJournal of Symplectic Geometry, 2016
64 pages. Final version. Appeared in Journal of Symplectic Geometry. Compared to previous version, some proofs have been improved in this version. The non-compact target case had an error in the earlier version, I am able to prove the result only for vector space targets ...

Basin and Petroleum Modelling of the Jammerbugt Structure: A Possible CO2 Storage Site in Skagerrak, Offshore Denmark

open access: yesJournal of GeoEnergy, Volume 2025, Issue 1, 2025.
Large‐scale carbon capture and storage (CCS) is essential for reducing CO2 emissions, and Denmark’s initial efforts targeted depleted oil fields in the outer North Sea. More recently, focus has shifted to saline aquifers located outside the established North Sea oil province. Unlike hydrocarbon (HC)‐bearing reservoirs, saline aquifers do not pose risks

Investigation of Phase Formation, As-cast Microstructure, Microhardness and 3D Porosity in Quaternary Al – 5 wt.% Si – 4 wt.% Cu – 1 wt.% Ni Alloy Obtained Under Transient Heat-Flow Conditions [PDF]

open access: yesMaterials Research
The present experimental investigation focuses on the phase formation, microstructural patterns, microhardness and 3D porosity for a quaternary Al – 5 wt.% Si – 4 wt.% Cu – 1 wt.% Ni alloy. Through the phase diagram and Thermo-Calc Scheil simulation, one

Evolving Subduction Zone Thermal Structure Drives Extensive Forearc Mantle Wedge Hydration

open access: yesAGU Advances, Volume 5, Issue 4, August 2024.
Abstract Hydration of the subduction zone forearc mantle wedge influences the downdip distribution of seismicity, the availability of fluids for arc magmatism, and Earth's long term water cycle. Reconstructions of present‐day subduction zone thermal structures using time‐invariant geodynamic models indicate relatively minor hydration, in contrast to ...

Investigating the Lid Effect on the Generation of Ocean Island Basalts: 1. Geochemical Trends

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract Ocean island basalts (OIBs) are generated by mantle plumes, with their geochemistry controlled by a combination of source composition, temperature, and thickness of overlying lithosphere. For example, OIBs erupting onto thicker, older oceanic lithosphere are expected to exhibit signatures indicative of higher average melting pressures.

Dynamic calculation of heat-flow coupled mine ventilation network with introduction of air volume fluctuation factor

open access: yesMeitan xuebao
To address the issue of continuous multi-scale fluctuations in air volume due to the thermal flow within the unsteady airflow medium in the ventilation system pipe domain, which limits the accuracy of system state mapping when using a static thermal ...
