Phytoplankton photophysiology across tropical eddies: Deconvolving nutrient, light, and community signals

open access: yesFrontiers in Marine Science, 2022
Fast repetition rate fluorometry (FRRf) based on active chlorophyll fluorescence is a powerful, noninvasive tool for studying phytoplankton physiological status at high spatial and temporal resolution.

Wind Forced Variability in Eddy Formation, Eddy Shedding, and the Separation of the East Australian Current [PDF]

open access: yes, 2017
The East Australian Current (EAC), like many other subtropical western boundary currents, is believed to be penetrating further poleward in recent decades.

Analysis of Runner Dynamics of Reversible Hydraulic Turbine by Alternating Fluid–Solid Action

open access: yesFrontiers in Energy Research, 2022
In order to study the effect of alternating fluid–solid action on the dynamic characteristics of the runner of a reversible hydraulic turbine, a reversible hydraulic turbine model is used as the research object, and the two-way fluid–solid coupling ...

Eddy-current loss in the rotor magnets of permanent-magnet brushless machines having a fractional number of slots per pole [PDF]

open access: yes, 2005
We develop an analytical model for predicting the eddy-current loss in the rotor magnets of permanent-magnet brushless machines that have a fractional number of slots per pole, when either all the teeth or only alternate teeth are wound, and in which the

Effect of eddy current in shielding plate and electron gun on flux distribution in CRT [PDF]

open access: yes, 2002
The eddy current induced in an inner magnetic shield (IMS) and an electron gun affect the flux distribution of a cathode ray tube, causing a possible degrade of picture quality.

Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic

open access: yesFrontiers in Marine Science, 2018
Microplastics are a ubiquitous pollutant in our seas today and are known to have detrimental effects on a variety of organisms. Over the past decade numerous studies have documented microplastic ingestion by marine species with more recent investigations

Wave and Meso-Scale Eddy Climate in the Arctic Ocean

open access: yesAtmosphere, 2023
Under global climate change, the characteristics of oceanic dynamics are gradually beginning to change due to melting sea ice. This study focused on inter-annual variation in waves and mesoscale eddies (radius > 40 km) in the Arctic Ocean from 1993 to ...

Scaling Laws and Regime Transitions of Macroturbulence in Dry Atmospheres [PDF]

open access: yes, 2008
In simulations of a wide range of circulations with an idealized general circulation model, clear scaling laws of dry atmospheric macroturbulence emerge that are consistent with nonlinear eddy–eddy interactions being weak.

Feasibility of Imaging Tissue Electrical Conductivity by Switching Field Gradients with MRI. [PDF]

open access: yes, 2015
Tissue conductivity is a biophysical marker of tissue structure and physiology. Present methods of measuring tissue conductivity are limited. Electrical impedance tomography, and magnetic resonance electrical impedance tomography rely on passing external

Influence of Different Substrates in Detoxification Activity of Adult Rat Hepatocytes in Long-Term Culture: Implications for Transplantation

open access: yesCell Transplantation, 1992
Substrates used to immobilize hepatocytes for transplantation govern attachment and long-term metabolic activity of these cells. The choice of these substrates is based on the familiarity with proteinaceous materials that are constituents of the ...
