"Many Antennas" typically refers to a concept in wireless communication and networking that involves using multiple antennas at the transmitter and/or receiver to improve performance. This technique is often associated with a broader set of technologies commonly known as Multiple Input Multiple Output (MIMO).
Maximal entropy random walk (MERW) is a probabilistic model used in the field of statistical mechanics, random processes, and complex networks. It is based on principles of entropy, particularly the notion of maximizing entropy under certain constraints. The fundamental idea is to model a random walker’s movement across a network or graph in such a way that the walker explores the space as evenly as possible, while still respecting the underlying structure of the graph.
Multi-user MIMO (MU-MIMO) is a wireless communication technology that enhances the capacity and efficiency of a network by allowing multiple users to simultaneously share the same frequency channel. It is a key feature in modern wireless systems, particularly in LTE (Long Term Evolution) and 5G networks. Here's how it works: 1. **Multiple Antennas**: In MU-MIMO, the base station (e.g., a cell tower) is equipped with multiple antennas.
Outage probability is a term commonly used in telecommunications and networking to quantify the likelihood that a system or communication link will fail to meet certain performance criteria, such as data transmission rates or signal quality. It refers to the probability that the quality of service (QoS) falls below a predefined threshold, leading to the inability to effectively transmit information.

Sanov's theorem is a result in statistical mechanics and large deviations theory that describes the asymptotic behavior of the empirical measures of independent random variables. It provides a way to understand how the probabilities of large deviations from the typical behavior of a stochastic system decay as the number of observations increases. Specifically, Sanov’s theorem states that for a sequence of independent and identically distributed (i.i.d.
Surprisal analysis is a concept rooted in information theory, primarily developed by Claude Shannon. It measures the amount of information or "surprise" associated with the occurrence of a particular event, which is based on the probability of that event. The basic idea is that events that have low probability are more surprising when they occur than events that are highly probable.
Total correlation is a concept from information theory and statistics that measures the amount of dependence or shared information among a set of random variables. Unlike mutual information, which quantifies the shared information between two variables, total correlation extends this idea to multiple variables.
The Uncertainty Coefficient, also known as the Uncertainty Measure or the Uncertainty Coefficient of a variable, is a statistical measure used to quantify the uncertainty associated with a random variable or the amount of information that one variable provides about another. It is especially relevant in information theory and statistics. ### Key Points: 1. **Definition**: The Uncertainty Coefficient measures how much knowing the value of one variable reduces the uncertainty about another variable.
A rondelet is a short poetic form consisting of a specific structure of lines and a repeated refrain. It typically consists of seven lines, with a rhyme scheme of a-b-a-a-b-a-a. The first line is repeated as the last line, and the second line is also repeated as the fourth line. This creates a circular feeling and reinforces the poem's themes. The rondelet is derived from the French word "rondeau," which refers to a type of verse that features a refrain.
Trumpler 14 is a young open star cluster located in the Carina Nebula, which is situated in the southern constellation of Carina. It is one of the largest and most massive star clusters in our Milky Way galaxy. Trumpler 14 was discovered by the American astronomer Robert Trumpler in the 1930s and is notable for containing a significant number of massive, hot stars, many of which are several times larger than the Sun.
"Anthony Stone" could refer to several things, depending on the context. Here are a few possibilities: 1. **Personal Name**: Anthony Stone may refer to an individual person, and could be a common name. 2. **Literature or Media**: It might also pertain to a character in a book, movie, or other media.
Anagrams are words or phrases that are formed by rearranging the letters of a different word or phrase, using all the original letters exactly once. For example, the word "listen" can be rearranged to form the word "silent." Anagrams are often used in word games and puzzles, and they can also be a fun way to create new words or phrases from existing ones. Some anagrams can lead to humorous or interesting combinations, adding to their appeal.
Natural units are a system of units in physics in which certain physical constants are set to 1. This simplifies many equations and relationships by eliminating the need for explicit reference to these constants. The most commonly used natural units involve the speed of light (\(c\)), the gravitational constant (\(G\)), and the reduced Planck constant (\(\hbar\)).
Heat waves are prolonged periods of excessively hot weather, which may be accompanied by high humidity. They are typically defined by meteorologists in various ways, but a common criterion is a significant rise in temperature that exceeds the average for a specific region and persists for an extended duration, usually several days or longer.
Americium is a synthetic chemical element with the symbol Am and atomic number 95. It is part of the actinide series on the periodic table and is produced through the neutron bombardment of plutonium. Discovered in 1944 by scientists Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso at the University of California, Berkeley, americium is named after the Americas.
Connect Four is a two-player board game in which players take turns dropping colored discs into a vertical grid that typically consists of six rows and seven columns. The objective of the game is to be the first player to connect four of their own discs in a row, either horizontally, vertically, or diagonally. Here's how the game is generally played: 1. **Setup**: The game board is placed upright, and both players choose a color (usually red or yellow).

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.
