k-Almost Newton-Conformal Ricci Solitons on Hypersurfaces Within Golden Riemannian Manifolds with Constant Golden Sectional Curvature

Axioms
The current work establishes the geometrical bearing for hypersurfaces in a Golden Riemannian manifold with constant golden sectional curvature with respect to k-almost Newton-conformal Ricci solitons.

Some Geometric Properties of Lorentzian $\beta$-Kenmotsu Manifolds Admitting $\eta$-Ricci-Yamabe Solitons

Communications in Advanced Mathematical Sciences
In this paper, we investigate the characterization of Lorentzian $\beta $-Kenmotsu manifolds admitting $\eta$-Ricci-Yamabe solitons. First, we examine the cases where such manifolds are Ricci pseudosymmetric and Ricci semisymmetric.

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 ...

On the Ricci Curvature of Normal-Metric Contact Pair Manifolds

Journal of New Theory, 2021
In this study, we work on normal-metric contact pair manifolds under certain conditions related to the Ricci curvature. We obtain some results for generalized quasi-Einstein normal-metric contact pair manifolds.

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 ...
