An autologous biologic pump motor
The Journal of Thoracic and Cardiovascular Surgery, 1986 Latissimus dorsi skeletal muscle ventricles were constructed in six beagles. They first underwent a period of vascular delay and of electrical preconditioning over several weeks. The skeletal muscle ventricles were then connected to a totally implantable mock circulation that allowed for the chronic measurement of pressures and flows produced by the ...

Summer net community production in the northern Chukchi Sea: Comparison between 2017 and 2020
Frontiers in Marine Science, 2022 The Arctic Ocean environment is drastically changing because of global warming. Although warming-induced processes, such as the decrease in sea-ice extent and freshening of the surface layer, have the potential to alter primary production, the changes ...

Subtropical Gyre Nutrient Cycling in the Upper Ocean: Insights From a Nutrient‐Ratio Budget Method
Geophysical Research Letters, 2023 We use a nutrient‐ratio budget method to investigate the relative importance of different nutrient source and sink terms at time‐series Station ALOHA and Bermuda Atlantic Time‐series Study (BATS) in the North Pacific and North Atlantic subtropical gyres,

Zooplankton and Micronekton Active Flux Across the Tropical and Subtropical Atlantic Ocean
Frontiers in Marine Science, 2019 Quantification of the actual amount of carbon export to the mesopelagic layer by both zooplankton and micronekton is at present a gap in the knowledge of the biological pump.

Multi-wavelength, all-solid-state, continuous wave mode locked picosecond Raman laser [PDF]
, 2010 We demonstrate the operation of a cascaded continuous wave (CW) mode-locked Raman oscillator. The output pulses were compressed from 28 ps at 532 nm down to 6.5 ps at 559 nm (first Stokes) and 5.5 ps at 589 nm (second Stokes).

Biological carbon pump estimate based on multidecadal hydrographic data [PDF]
Nature, 2023 AbstractThe transfer of photosynthetically produced organic carbon from surface to mesopelagic waters draws carbon dioxide from the atmosphere1. However, current observation-based estimates disagree on the strength of this biological carbon pump (BCP)2.

Bacterial Succession on Sinking Particles in the Ocean's Interior
Frontiers in Microbiology, 2017 Sinking particles formed in the photic zone and moving vertically through the water column are a main mechanism for nutrient transport to the deep ocean, and a key component of the biological carbon pump.
