Role of Ubiquitin and Ubiquitin Ligases in Retroviral Budding
… stage in the production of infectious retroviral particles is the scission of membrane tethers connecting nascent virions to the host cell. Efficient retrovirus release requires late domains, short peptide motifs within the structural Gag proteins that engage the cellular Class E vacuolar protein …

Numerical and analytical studies of single and multiphase starting jets and plumes
… including phase separation and the effect of particle release conditions. The most popular similarity law to scale up from the lab to the field (Cloud number scaling) is validated by a series of simulations. Finally, an example of sediment disposal in the field is given based on the present …

Detection and localization of aerosol releases from sparse sensor measurements
… addressing two aspects pertinent to biological release detection. The first is that of detecting and localizing an aerosolized particle release using a sparse array of sensors. The problem is challenging for several reasons. It is often the case that sensors are costly and consequently only a …

Trait-based modeling of larval dispersal in the Gulf of Maine
… models (IBMs) that couple ocean circulation and particle-tracking models provide a unique ability to examine larval dispersal patterns with high spatial and temporal resolution. Obtaining accurate results with IBMs requires simulating a sufficient number of particles, and the sequential Bayesian …

Characterization of carbon ablators for hypersonic thermal protection systems
… representative of atmospheric entry. Spalled particles from FiberForm and PICA wedges were tracked using high-speed imaging, enabling time-resolved analysis of spallation events. Tests in nitrogen revealed high variance in particle production over time, while tests in air exhibited steady …

Quantifying emissions of greenhouse gases from South Asia through a targeted measurement campaign
… thermally driven winds is seasonally present. A particle dispersion model is used to track 'air histories' of measurements, quantifying the sensitivity of concentrations at Darjeeling to surface emissions. The effect of topography on the derived air histories is investigated to test the …

Coastal sources of estuarine inflow
… in 2016. Green crab spawns were simulated using particle tracking experiments in an ocean model of the eastern Pacific Ocean to investigate the likelihoods that larvae released from four potential source locations on the West Coast could be successfully transported into the eastern Salish Sea. …

Modelling the effects of spatio-temporal spawning variability on the transport and retention success of sardine (Sardinops sagax) eggs and larvae around South Africa
… Africa were investigated using a Lagrangrian, particle tracking, individual-based model (IBM), coupled with two 3-D hydrodynamic Regional Ocean Modeling System (ROMS) model configurations of different generations. The same IBM is coupled with PLUME, an older ROMS model configuration used in a …

Determinanten und Mechanismen der foamyviralen Partikelfreisetzung
Die Spumaretrovirinae, mit ihrer einzigen Gattung der Foamyviren (FV), nehmen aufgrund einer recht ungewöhnlichen Replikationsstrategie und Ähnlichkeiten mit den Hepadnaviren eine Sonderstellung innerhalb der Familie der Retroviren ein. Eine Besonderheit der FV ist, daß sie für die …
