A Hardy field is a type of mathematical structure used in the field of real analysis and model theory, specifically in the study of asymptotic behaviors of functions. It is named after the mathematician G. H. Hardy. A Hardy field is essentially a field of functions that satisfies certain algebraic and order properties.
Kleene algebra is a mathematical structure used in theoretical computer science, formal language theory, and algebra. It is named after the mathematician Stephen Kleene, who made significant contributions to the foundations of automata theory and formal languages. Kleene algebra consists of a set equipped with certain operations and axioms that support reasoning about the properties of regular languages and automata.
In algebra, particularly in the context of ring theory, the term "rng" (pronounced "ring") is an abbreviation that refers to a mathematical structure that is similar to a ring but does not necessarily require the existence of a multiplicative identity (i.e., an element that acts as 1 in multiplication).
A **semigroupoid** is an algebraic structure that generalizes the notion of a semigroup to a situation where the elements can be thought of as processes or mappings rather than simple algebraic objects. More formally, a semigroupoid can be defined as a category in which every morphism (or arrow) is invertible, but it has a single object, or it can be thought of as a partially defined operation among elements.
As of my last update in October 2023, Yasmine Amhis does not appear to be a widely recognized public figure, concept, or term in popular culture, politics, science, or other notable fields. It's possible that she could be a private individual or a rising figure not widely documented in mainstream sources up to that time.
Minimum Description Length (MDL) is a principle from information theory and statistics that provides a method for model selection. It is based on the idea that the best model for a given set of data is the one that leads to the shortest overall description of both the model and the data when encoded. In essence, it seeks to balance the complexity of the model against how well the model fits or explains the data.
Proxima Centauri is a red dwarf star located in the Alpha Centauri star system, which is the closest star system to Earth, situated about 4.24 light-years away. Proxima Centauri is the smallest and faintest of the three stars in this system, the other two being Alpha Centauri A and Alpha Centauri B, which are more similar to our Sun.
Sequence alignment is a bioinformatics method used to arrange sequences of DNA, RNA, or proteins to identify regions of similarity and difference. This process is crucial for understanding evolutionary relationships, functional similarities, and structural characteristics among biological sequences. There are two primary types of sequence alignment: 1. **Global Alignment**: This method aligns sequences from start to finish, ensuring that every residue in the sequences is aligned. It is typically used when comparing sequences that are of similar length and contain many conserved regions.

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.
