High-Frequency Variations in Pearl River Plume Observed by Soil Moisture Active Passive Sea Surface Salinity

open access: yesRemote Sensing, 2020
River plumes play an important role in the cross-margin transport of phytoplankton and nutrients, which have profound impacts on coastal ecosystems. Using recently available Soil Moisture Active Passive (SMAP) sea surface salinity (SSS) data and high ...

A Computational Model for Tail Undulation and Fluid Transport in the Giant Larvacean

open access: yesFluids, 2021
Flexible propulsors are ubiquitous in aquatic and flying organisms and are of great interest for bioinspired engineering. However, many animal models, especially those found in the deep sea, remain inaccessible to direct observation in the laboratory. We

The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web

open access: yesFrontiers in Marine Science, 2019
We used extensive ecological and biogeochemical measurements obtained from quasi-Lagrangian experiments during two California Current Ecosystem Long-Term Ecosystem Research cruises to analyze carbon fluxes between the epipelagic and mesopelagic zones ...

Uncharted routes: exploring the relevance of auxin movement via plasmodesmata

open access: yesBiology Open, 2020
Auxin is an endogenous small molecule with an incredibly large impact on growth and development in plants. Movement of auxin between cells, due to its negative charge at most physiological pHs, strongly relies on families of active transporters.

The Process of Thermodialysis and Some of its Possible Consequences in Biology

open access: yesCHIMIA, 1976
The flow of thermal energy in liquids is associated with the development of ponderomotive forces. In non-isothermal ionic or molecular solutions a drift of the disperse phase is thus produced (thermal diffusion).

Uptake and transport of antibiotic kasugamycin in castor bean (Ricinus communis L.) seedlings

open access: yesFrontiers in Microbiology, 2022
Kasugamycin (KSM), an aminoglycoside antibiotic, has been widely used for the management of plant diseases, especially for the control of rice blast in Asia. However, its uptake mechanism and transport in plants are still obscure.

Review: Interactions of Active Colloids with Passive Tracers

open access: yesCondensed Matter, 2019
Collective phenomena existing universally in both biological systems and artificial active matter are increasingly attracting interest. The interactions can be grouped into active-active and active-passive ones, where the reports on the purely active ...
