Hemispheric Geochemical Dichotomy of the Mantle Is a Legacy of Austral Supercontinent Assembly and Onset of Deep Continental Crust Subduction

open access: yesAGU Advances, 2022
Oceanic hotspots with extreme enriched mantle radiogenic isotopic signatures—including low 143Nd/144Nd indicative of subducted continental crust—are linked to plume conduits sampling the southern hemispheric mantle.

On the Potential of Relational Databases for the Detection of Clusters of Infection and Antibiotic Resistance Patterns

open access: yesAntibiotics, 2023
In recent years, several bacterial strains have acquired significant antibiotic resistance and can, therefore, become difficult to contain. To counteract such trends, relational databases can be a powerful tool for supporting the decision-making process.

UAV-Aided Offloading for Cellular Hotspot [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2017
In conventional terrestrial cellular networks, mobile terminals (MTs) at the cell edge often pose a performance bottleneck due to their long distances from the serving ground base station (GBS), especially in the hotspot period when the GBS is heavily ...
