A memory cache policy that sends a write miss onward without allocating the missed cache line in that level. Different levels of a cache hierarchy may use different write policies.
Loss of useful cached data because less useful data occupy the limited memory cache. Excessive cache prefetching can increase later demand cache misses by evicting useful cache lines.
Consistency requirements for cached copies of the same memory location, including agreement on its writes. Cache coherence does not itself impose sequential consistency across different locations.
The ventricular system is the connected set of fluid-filled cavities within the brain, continuous caudally with the central canal of the spinal cord. Cerebrospinal fluid passes between ventricular compartments and the surrounding subarachnoid spaces through defined openings.
The brainstem connects the spinal cord with more rostral parts of the brain and includes the medulla oblongata, pons and midbrain. Its pathways and nuclei participate in sensory, motor and autonomic functions. A compact region can therefore support several interacting systems.
Intracranial pressure is the pressure within the cranial compartment, commonly assessed through a specified fluid or tissue measurement. Brain tissue, blood and cerebrospinal fluid share a constrained space. Changes in their volumes and drainage therefore interact rather than acting as isolated pressures.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
