The new SCIARA-fv3 numerical model and acceleration by GPGPU strategies

The International Journal of High Performance Computing Applications, 2016
This paper presents the parallel implementation, using the Compute Unified Device Architecture (CUDA) architecture, of the SCIARA-fv3 Complex Cellular Automata model for simulating lava flows. The computational model is based on a Bingham-like rheology and both flow velocity and the physical time corresponding to a computational step have been made ...

Budding of frog virus 3 (FV3) studied by means of sequential immunocytochemical labeling

Journal of Ultrastructure Research, 1976
In FV3-infected cells, viral antigens appear in those areas of the cell membrane in close contact with budding virions. Owing to a lack of synchronization in the budding process, metabolic inhibitors could not be used up to now to study the requirements for this process nor the antigenic modifications ensuing.

EXPERIMENTAL CHALLENGE STUDY OF FV3-LIKE RANAVIRUS INFECTION IN PREVIOUSLY FV3-LIKE RANAVIRUS INFECTED EASTERN BOX TURTLES (TERRAPENE CAROLINA CAROLINA) TO ASSESS INFECTION AND SURVIVAL

Journal of Zoo and Wildlife Medicine, 2015
The Maryland Zoo in Baltimore experienced an outbreak of Frog virus-3 (FV3)-like ranavirus during the summer of 2011, during which 14 of 27 (52%) of its captive eastern box turtles (Terrapene carolina carolina) survived. To assess survival, immunity, and viral shedding, an experimental challenge study was performed in which the surviving, previously ...

Implementation Of The Novel Duo-Grid Within The GFDL FV3 Dynamical Core

2023
The current edge handling of the cubed sphere grid introduces numerical errors in simulations and creates grid imprinting due to the discontinuity of the great­-circle grid lines between two adjacent tiles. In this work, we implement a new edge/corner handling method to greatly reduce the grid imprinting in GFDL's dynamical core FV3. First, we

Penetration and uncoating of frog virus 3 (FV3) in cultured rat Kupffer cells

Virology, 1981
Abstract The in vitro interactions between unenveloped frog virus 3 and Kupffer cells have been studied at 37°, a nonpermissive temperature for viral multiplication. Kupffer cells were isolated by collagenase perfusion of rat livers followed by purification of the cells by centrifugal elutriation.

Surface‐dependent correlated infrared observation errors and quality control in the FV3 framework

Quarterly Journal of the Royal Meteorological Society, 2020
AbstractData assimilation relies on the accurate representation of both observation‐ and background‐error statistics. In this study, the Desroziers diagnostic is used to estimate error covariance matrices for CrIS and IASI brightness temperature observations over land and sea surfaces.

Negative Effects of Low Dose Atrazine Exposure on the Development of Effective Immunity to FV3 in Xenopus laevis [PDF]

Developmental and Comparative Immunology, 2014
The recent dramatic increase of the prevalence and range of amphibian host species and populations infected by ranaviruses such as Frog Virus 3 (FV3) raises concerns about the efficacies of amphibian antiviral immunity. In this context, the potential negative effects of water contaminants such as the herbicide atrazine, at environmentally relevant ...

Assimilating GOES-R Latent Heating in FV3 using Machine Learning

2020
Imagery from the GOES series has been a key element of U.S. operational weather forecasting for four decades. While GOES observations are used extensively by human forecasters for situational awareness, there has been limited usage of GOES imager data in numerical weather prediction (NWP), and operational data assimilation (DA) has ignored cloud and ...

Alterations of plasma lipoproteins and hepatic lipid biosynthesis in FV3-induced hepatitis in mice

Experimental and Molecular Pathology, 1982
Abstract The study of lipid metabolism in toxic hepatitis induced by FV3 enabled us to demonstrate, 10 hr after inoculation of a 100% lethal dose of viral particles: (1) A decrease in plasma lipid concentration, as well as a 50% diminution of nonesterified fatty acids; (2) An alteration of plasma lipoprotein profile characterized by decreases in VLDL,

Complete Genome Analysis of a Frog Virus 3 (FV3) Isolate and Sequence Comparison With Isolates of Differing Levels of Virulence [PDF]

Virology Journal, 2014
Frog virus 3 (FV3) is the type species of the genus Ranavirus, and in the past few decades, FV3 infections have resulted in considerable morbidity and mortality in a range of wild and cultivated amphibian species in the Americas, Europe, and Asia.
