The Lauricella hypergeometric series is a generalization of the classical hypergeometric series and is denoted as \( F_D \). It is a function of several variables and is defined for several complex variables. It generalizes the standard hypergeometric series, which is a function of one variable, to cases with multiple parameters and arguments.
The Law of Identity is a fundamental principle in classical logic and philosophy, often expressed succinctly as "A is A." This means that an object is identical to itself and that it possesses all the properties that define it. In other words, for any entity or proposition, it is identical to itself and distinct from any other entity or proposition. The Law of Identity can be formally stated as: - If something is true (or holds), then it is true (or holds).
"Leaf power" can refer to different concepts depending on the context in which it is used. Below are a few interpretations: 1. **Botanical Context**: In the field of botany, "leaf power" might refer to the ability of leaves to perform photosynthesis, which converts sunlight into chemical energy. This process is essential for plant growth and oxygen production.
Least Frequently Used (LFU) is a cache eviction algorithm that removes the least frequently accessed items when the cache reaches its capacity. The main idea behind LFU is to maintain a count of how many times each item in the cache has been accessed. When a new item needs to be added to the cache and it is full, the algorithm identifies the item with the lowest access count and evicts it.

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.Figure 1. Screenshot of the "Derivative" topic page.
