Tellegen's theorem is a fundamental principle in network theory and electrical engineering, formulated by Bernard Tellegen in 1952. It is a powerful statement about the conservation of energy in electrical networks, which can be applied to both linear and nonlinear circuits. The theorem asserts that for any network of interconnected electrical components, the total power entering the network is equal to the total power leaving the network when considering all the elements simultaneously, assuming that they are in a balanced state.
A differential game is a type of mathematical game that involves multiple players (or agents) who make decisions over time, where the evolution of the system is described by differential equations. In these games, players aim to optimize their own objectives, taking into account the dynamics of the system and the strategies of other players. Differential games blend concepts from game theory and control theory. ### Key Features of Differential Games: 1. **Dynamic Systems**: The state of the game evolves over time according to differential equations.
Meshulam's game is a mathematical game in combinatorial game theory named after the mathematician A. Meshulam. It involves two players taking turns to color squares in a grid, with specific rules that determine the winning conditions based on the colors chosen. The details of the game can vary, but it typically involves strategic decision-making, foresight, and planning to secure a win.
Notakto is a two-player abstract strategy game that is a variation of the classic game Tic-Tac-Toe (also known as Naughts and Crosses). It is played on a grid, typically 3x3, where players take turns placing their symbols (commonly X and O) in the empty spaces. The objective is to get a certain number of symbols in a row, similar to Tic-Tac-Toe.
The Octal Game is a mathematical game that typically involves two players taking turns to remove objects from a pile. Each player can remove a specific number of objects (usually between one and a maximum number determined by the game rules) on their turn. The objective is to force the opponent into a position where they can only make losing moves. While there are various interpretations and variations of this game, it generally emphasizes strategic thinking and can be analyzed using concepts from combinatorial game theory.
"Subtract a square" typically refers to a mathematical process involving the subtraction of the square of a number from another number or expression. In a more general mathematical context, it may also refer to a method used in algebra or number theory where one analyzes expressions of the form \(x^2 - y^2\), which can be factored as \((x+y)(x-y)\).
Calcium-activated potassium channel subunit alpha-1 is a protein that plays a crucial role in regulating potassium ion (K+) flow across cell membranes. It is encoded by the **KCNMA1** gene in humans. The protein is part of the large conductance calcium-activated potassium (BK) channel family, which is known for its ability to be activated by both intracellular calcium ions and membrane depolarization.
The term "inverted bell" can refer to different concepts depending on the context: 1. **Statistics**: In statistics, an inverted bell curve typically describes a distribution where the values are concentrated at the extremes rather than the middle. This is the opposite of the normal bell curve (Gaussian distribution), which is symmetrical around the mean. An inverted bell curve can suggest a scenario where there are more outliers or extreme values than average ones.
KCNMB3 is a gene that encodes a protein known as the potassium calcium-activated channel subfamily M member 3. This protein is part of a family of ion channels that are important for various physiological functions, particularly in the nervous and cardiovascular systems. KCNMB3 is known to form a subunit of large conductance calcium-activated potassium (BK) channels, which play a crucial role in regulating membrane potential and calcium signaling in cells.
Photo-oxidation of polymers refers to the chemical reactions that occur in polymers due to exposure to light (particularly ultraviolet (UV) light) and oxygen. This process can lead to the degradation of polymer materials, affecting their physical and chemical properties. ### Key Points about Photo-Oxidation of Polymers: 1. **Mechanism**: - Photons provide energy that can excite electrons in polymer chains, leading to the formation of free radicals.
A **propositional proof system** is a formal system in mathematical logic that is used to establish the validity of propositional formulas. It consists of a set of rules and axioms that allow for the derivation of logical statements from other statements. The goal of such a system is to demonstrate that certain propositions can be proven true based on established truths, regardless of the specific interpretation of the involved propositions.
The Protein Circular Dichroism Data Bank (PCDDB) is a specialized database that provides access to circular dichroism (CD) spectroscopy data specifically for proteins. Circular dichroism is a spectroscopic technique that is used to study the secondary and tertiary structures of proteins by measuring the differential absorption of left-handed and right-handed circularly polarized light. The PCDDB serves as a repository for CD data, allowing researchers to upload and share their findings.
Cannon's algorithm is a method for matrix multiplication that is designed to be efficient on distributed memory systems, and particularly for systems with a grid structure, such as clusters of computers or multicomputer architectures. Developed by the computer scientist William J. Cannon in 1969, the algorithm leverages the concept of data locality and aims to reduce communication overhead, making it suitable for parallel processing. ### Overview of Cannon's Algorithm 1.
Cantor's isomorphism theorem is a fundamental result in set theory that concerns the relationships between different infinite sets. More specifically, it relates to the structure of certain types of infinite sets and their cardinalities. The theorem states that: 1. **Every set can be mapped to a \(\sigma\)-algebra**: A measurable space can be constructed from any set.
Lenur Arifov appears to be a name rather than a widely recognized term or entity. Without further context, it’s difficult to provide specific information. If Lenur Arifov is a person, their prominence may vary based on their field of work, location, or any recent developments post-2021 that I may not be aware of. Please provide more details or clarify the context regarding Lenur Arifov for a more accurate response.
Carathéodory's criterion is a theorem related to the characterization of measurable sets in the context of measure theory. Specifically, it provides a way to determine whether a set is Lebesgue measurable.
Padding algorithms are techniques used in cryptography and data processing to ensure that data blocks conform to certain size requirements, often making them uniform for further processing or encryption. Many cryptographic algorithms, particularly block ciphers (like AES or DES), operate on fixed-size blocks of data. If the input data does not fill an entire block, padding is added to meet the block size requirements. ### Purpose of Padding 1.
Proto-cuneiform numerals refer to an early system of writing that was used in ancient Mesopotamia, primarily by the Sumerians around the end of the 4th millennium BCE. Proto-cuneiform is one of the earliest known forms of writing and is characterized by its use of pictographs and ideograms.

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.
