Autonomous, high-resolution observations of particle flux in the oligotrophic ocean [PDF]
Biogeosciences, 2013 Observational gaps limit our understanding of particle flux attenuation through the upper mesopelagic because available measurements (sediment traps and radiochemical tracers) have limited temporal resolution, are labor-intensive, and require ship ...

Flux String in Quantum Billiards with Two Particles [PDF]
Physics Letters A, 1996 We examine the quantum motion of two particles interacting through a contact force which are confined in a rectangular domain in two and three dimensions. When there is a difference in the mass scale of two particles, adiabatic separation of the fast and

Flux-Across-Surfaces Theorem for a Dirac Particle [PDF]
Journal of Mathematical Physics, 2002 We consider the asymptotic evolution of a relativistic spin-1/2-particle. i.e. a particle whose wavefunction satisfies the Dirac equation with external static potential.

Seep-carbonate lamination controlled by cyclic particle flux. [PDF]
Sci Rep, 2016 AbstractAuthigenic carbonate build-ups develop at seafloor methane-seeps, where microbially mediated sulphate-dependent anaerobic oxidation of methane facilitates carbonate precipitation. Despite being valuable recorders of past methane seepage events, their role as archives of atmospheric processes has not been examined.

Frontiers in Marine Science, 2021 The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in the face of strong inter-annual ...

Energy Flux and Particle Flux in Steady-state Solutions of Nuclear Star Clusters
The Astrophysical Journal, 2023 We examine the effects of two-body interactions in a nuclear star cluster surrounding a supermassive black hole. We evaluate the energy flux, analogously to the particle flux calculation of Bahcall and Wolf.

Modeling on Effect of Particle Sediment on Fluid Flow and Heat Transfer of Solid–Fluid Suspension
Energies, 2021 A two-way coupling particle flux model is proposed for studying the multi-component solid–fluid suspension. The suspension mixture is treated as a non-linear single-phase fluid and the migration of the solid particles is modeled by a particle flux ...

Measurements and modeling of type-I and type-II ELMs heat flux to the DIII-D divertor
Nuclear Fusion, 2023 Type-I and type-II edge-localized-modes (ELMs) heat flux profiles measured at the DIII-D divertor feature a peak in the vicinity of the strike-point and a plateau in the scrape-off-layer (SOL), which extends to the first wall.

Influence of atmospheric dust deposition on sinking particle flux in the northwest Pacific
Frontiers in Marine Science, 2023 We examined the flux and composition of sinking particles collected at a water depth of 800 m in the northwest Pacific from November 2017 to August 2018 to assess the impact of dust deposition on organic carbon export.
