Seasonal to Interannual Cross‐Scale Energy Transfer Variability: Observational Insight From the Santa Barbara Channel

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Kinetic energy (KE) transfer between spatial scales contributes to the ocean's energy budget by linking scales of KE supply and KE dissipation. Numerical simulations have indicated that for scales smaller than the baroclinic deformation radius, cross‐scale KE transfer has complex spatial and temporal variability, modulated by mixed layer ...

Liquid vertical bar liquid ion-transfer processes at the dioctylphosphoric acid (N,N-didodecyl-N ',N '-diethylphenylenediamine)vertical bar water (electrolyte) interface at graphite and mesoporous TiO2 substrates

open access: yes, 2004
Biphasic electrode systems are studied for the case of the oxidation of the water-insoluble liquid N,N-didodecyl-N',N',-diethylphenylenediamine (DDPD) neat and dissolved in bis(2-ethylhexyl) phosphate (HDOP) and immersed in aqueous electrolyte media. The

Global self-localization and navigation using 3D-LiDAR for headland turning in vineyards

open access: yesSmart Agricultural Technology
When using the real-time kinematic global navigation satellite system (RTK-GNSS) in orchards or vineyards, autonomous navigation can be disrupted due to the inability to obtain ambiguity-fixed solutions.

Moving wildlife tracking forward under forested conditions with the SWIFT GPS algorithm

open access: yesAnimal Biotelemetry, 2022
The remote collection of animal location data has proliferated in recent decades, and higher-frequency data are increasingly available with battery-saving optimisations such as ‘snapshot’ algorithms that acquire GPS satellite data and post-process ...

Living on the Edge: Juvenile Foraging and Adult Breeding Ecology of an Aerial Top Predator in Urban Environments

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed a combination of GPS tracking data and nest‐monitoring data from an urban population of an opportunistic rodent specialist, the Common Buzzard (Buteo buteo), to analyze how raptors utilize urban landscapes. Buzzards occupied even extreme habitats such as residential areas for foraging and breeding and benefit from lucrative foraging ...

A Multi‐Scale Approach to Assessing Positioning Accuracy in High‐Density Urban Environments of Hong Kong

open access: yesTransactions in GIS, Volume 30, Issue 1, February 2026.
ABSTRACT This study examined GPS positioning accuracy in high‐density urban environments using Hong Kong as a representative case study. Through field measurements along 32 testing routes using three GPS devices, we evaluated GPS performance across diverse urban morphologies to assess associations between complex urban characteristics and positioning ...
