Real representation can refer to different concepts depending on the context in which it is used. Here are a few interpretations: 1. **Mathematics**: In mathematics, particularly in real analysis, a "real representation" often refers to expressing a mathematical object or function explicitly in terms of real numbers. For example, representing complex numbers in terms of their real and imaginary components.
The Fragility Index is a statistical measure used primarily in the field of clinical research and evidence-based medicine to assess the robustness of the results of clinical trials, particularly in relation to binary outcomes (e.g., yes/no, success/failure). It quantifies how many patients would need to be reassigned to the opposite treatment group in order for the trial results to become statistically non-significant.
Automated whole-breast ultrasound (AWBU) is a medical imaging technique used primarily in breast cancer screening and diagnosis. Unlike traditional hand-held ultrasound, which requires a sonographer to manually move the transducer over the breast, automated whole-breast ultrasound utilizes a specialized device that automatically captures images of the entire breast.
Portable ultrasound refers to ultrasound equipment that is designed to be compact, lightweight, and easily transportable. Unlike traditional ultrasound machines that are typically large and require a fixed installation, portable ultrasound devices can be used in various settings, including clinics, emergency rooms, ambulances, and even in patients' homes. Key features of portable ultrasound devices include: 1. **Size and Weight**: These machines are generally smaller and lighter than traditional models, making them easier to handle and move.
The 117th meridian west is an imaginary line of longitude that is located 117 degrees west of the Prime Meridian. This meridian runs from the North Pole to the South Pole, passing through several U.S. states, including parts of Montana, Wyoming, Colorado, New Mexico, and California. It also crosses into Mexico and runs through various landscapes, such as mountains, plains, and desert regions.

Minimal example. Gives a hint at how boilerplate heavy Sphinx can be!

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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. 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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
