Multiparametric Ultrasound Findings of Testicular Sarcoidosis

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives To characterize the multiparametric ultrasound (MPUS) features of testicular sarcoidosis, incorporating greyscale, color Doppler ultrasound (CDUS), contrast‐enhanced ultrasound (CEUS), and strain elastography (SE), and to assess their collective diagnostic value.

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

Combining the Underwater Vision Profiler 6 with sediment traps to measure in situ velocity of marine particles

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation

open access: yesLaser &Photonics Reviews, EarlyView.
Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized
