Bilateral trigeminal nerve sheath tumors treated with stereotactic radiosurgery: A case report

open access: yesInterdisciplinary Neurosurgery, 2021
Bilateral trigeminal nerve sheath tumors are extremely rare with a paucity of previously disseminated cases. In addition, bilateral nerve sheath tumors are often secondary to genetic conditions such as Neurofibromatosis (NF) 2 and schwannomatosis.

Stationary mesoscale eddies, upgradient eddy fluxes, and the anisotropy of eddy diffusivity [PDF]

open access: yesGeophysical Research Letters, 2016
AbstractThe mesoscale eddies of which parameterization is needed in coarse‐resolution ocean models include not only the transient eddies akin to baroclinic instability but also the stationary eddies associated with topography. By applying a modified Lorenz‐type decomposition to the eddy‐permitting Southern Ocean State Estimate, we show that the ...

Flow rate measurement in aggressive conductive fluids

open access: yesEPJ Web of Conferences, 2014
Two non-contact experimental methods of flow rate measurements for aggressive conductive liquids are described. The techniques are based on electromagnetic forces and Faraday’s law: Lorentz force is induced inside moving conductive liquid under influence

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

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 ...

The Eddy-Driven Thermocline

open access: yesJournal of Physical Oceanography, 2004
Abstract The role of baroclinic eddies in transferring thermal gradients laterally, and thus determining the stratification of the ocean, is examined. The hypothesis is that the density differences imposed at the surface by differential heating are a source of available potential energy that can be partially released by mesocale eddies ...

An extraordinary chlorophyll-a enhancement event jointly induced by two sequential tropical cyclones in the Kuroshio region south of Japan

open access: yesFrontiers in Marine Science, 2023
We used Biogeochemical-Argo (BGC-Argo) float observation profiles and satellite data to investigate the physical-biogeochemical processes of a phytoplankton biomass rise in the Kuroshio region south of Japan during a period of two sequential tropical ...

Oceanographic Structure and Light Levels Drive Patterns of Sound Scattering Layers in a Low-Latitude Oceanic System

open access: yesFrontiers in Marine Science, 2020
Several factors have been reported to structure the spatial and temporal patterns of sound scattering layers, including temperature, oxygen, salinity, light, and physical oceanographic conditions. In this study, we examined the spatiotemporal variability

An Intestine-Derived Neuropeptide Controls Avoidance Behavior in Caenorhabditis elegans

open access: yesCell Reports, 2017
Adjusting to a continuously changing environment is a key feature of life. For metazoans, environmental changes include alterations in the gut microbiota, which can affect both memory and behavior.
