Avastrovirus

Avastrovirus is a genus of viruses, in the family Astroviridae. Birds serve as natural hosts. There are currently three species in this genus including the type species Avastrovirus 1. Diseases associated with this genus include: gastroenteritis, liver or kidney damages.[1][2]

Structure

Viruses in Avastrovirus are non-enveloped, with icosahedral and Spherical geometries, and T=3 symmetry. The diameter is around 35 nm. Genomes are linear and non-segmented, around 6.8-7kb in length.[1]

Life cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment to host receptors, which mediates endocytosis. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription, using an unknown model of subgenomic rna transcription is the method of transcription. Translation takes place by -1 ribosomal frameshifting. Birds serve as the natural host. Transmission routes are fecal-oral.[1]

gollark: This application is LITERALLY a particle of weight W placed on a rough plane inclined at an angle of θ to the horizontal. The coefficient of friction between the particle and the plane is μ. A horizontal force X acting on the particle is just sufficient to prevent the particle from sliding down the plane; when a horizontal force kX acts on the particle, the particle is about to slide up the plane. Both horizontal forces act in the vertical plane containing the line of greatest slope.
gollark: Fiiiiine.
gollark: I agree. It's precisely [NUMBER OF AVAILABLE CPU THREADS] parallelized.
gollark: > While W is busy with a, other threads might come along and take b from its queue. That is called stealing b. Once a is done, W checks whether b was stolen by another thread and, if not, executes b itself. If W runs out of jobs in its own queue, it will look through the other threads' queues and try to steal work from them.
gollark: > Behind the scenes, Rayon uses a technique called work stealing to try and dynamically ascertain how much parallelism is available and exploit it. The idea is very simple: we always have a pool of worker threads available, waiting for some work to do. When you call join the first time, we shift over into that pool of threads. But if you call join(a, b) from a worker thread W, then W will place b into its work queue, advertising that this is work that other worker threads might help out with. W will then start executing a.
