Queue‐Aware Congestion Avoidance in IoHT: Enabling Future Integration With Large Models for Transmission Optimization

Internet Technology Letters, Volume 8, Issue 6, November/December 2025.
ABSTRACT The internet of healthcare things (IoHT) has advanced considerably, improving healthcare operations and patient monitoring by continuously collecting data from health sensors attached to patients. Current congestion detection techniques are insufficient for early detection since senders often remain unaware of the size of the residual queue ...

MarineFlux ICOADS Air‐Sea Fluxes: 1990–2020

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
The MarineFlux project derived bulk turbulent heat and momentum fluxes from individual ship and buoy reports available in ICOADS Release 3 for 1990–2020. The fluxes are freely available from an ERDDAP service for use in developing new gridded products and assessing variations in air‐sea energy exchanges. ABSTRACT Bulk turbulent heat and momentum fluxes

Dynamic Mode Decomposition of Geostrophically Balanced Motions From SWOT Cal/Val in the Separated Gulf Stream

Earth and Space Science, Volume 12, Issue 8, August 2025.
Abstract The decomposition of oceanic flow into its geostrophically balanced and unbalanced motions carries theoretical and practical significance for the oceanographic community. These two motions have distinct dynamical characteristics and affect the transport of tracers differently from one another.

Dynamics and Thermodynamics of the Boussinesq North Atlantic Eddy Kinetic Energy Spectral Budget

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 4, April 2025.
Abstract Statistical characterization of oceanic flows has been a long standing issue; such information is invaluable for formulating hypotheses and testing them. It also allows us to understand the energy pathways within the ocean, which is highly turbulent.
