Affinity magnetic separation is a technique used to isolate or purify specific biomolecules, such as proteins, nucleic acids, or cells, based on their affinity to magnetic particles. This method combines the principles of affinity chromatography and magnetic separation. Here's a general overview of how it works: 1. **Magnetic Particles**: The process involves the use of magnetic beads or particles that are coated with specific ligands (molecules that can bind to the target of interest).
A Hermite spline is a type of piecewise-defined curve that is particularly useful in computer graphics and animation for smoothly interpolating between two or more points. The defining characteristic of Hermite splines is that they are defined by their endpoints and associated tangents (or derivatives) at these endpoints. This makes them versatile for creating smooth curves that pass through specified points with controlled slopes.
The term "Global Brain" can refer to several concepts, depending on the context in which it is used. Here are the most common interpretations: 1. **Collective Intelligence**: The Global Brain concept often describes the collective intelligence that emerges from the interactions and connections among individuals worldwide, facilitated by technology and the internet.
Fractional-order control refers to a control strategy that utilizes fractional-order calculus, which extends traditional integer-order calculus to non-integer (fractional) orders. This approach allows engineers and control theorists to model and control dynamic systems with a greater degree of flexibility and complexity than traditional integer-order controllers.
L-stability is a concept related to numerical analysis, particularly in the context of solving ordinary differential equations (ODEs) and partial differential equations (PDEs) using numerical methods. It is a property of a numerical method that ensures stable behavior when applied to stiff problems. In essence, L-stability refers to the ability of a numerical method to dampen apparent oscillations or instabilities that arise from stiff components of the solution, particularly as the step size tends to zero.
A self-concordant function is a specific type of convex function that has properties which make it particularly useful in optimization, especially in the context of interior-point methods.
An atmospheric river is a narrow, elongated corridor of concentrated moisture in the atmosphere. These phenomena can transport large amounts of water vapor from tropical regions toward higher latitudes, particularly affecting coastal areas. The water vapor can then condense and fall as precipitation, leading to significant rainfall or snowfall when the moist air is lifted over mountains or cooler regions. Atmospheric rivers can vary in intensity and duration and are categorized into different levels based on their impact.
Charybdis is a figure from Greek mythology, typically depicted as a sea monster that poses a significant threat to sailors. She is often described as a whirlpool that devours water and anything caught in it, creating a dangerous and treacherous passage. Charybdis is frequently paired with another mythical creature, Scylla, with whom she is situated on opposite sides of a narrow strait, most famously depicted in Homer's "Odyssey.
The atomic number is a fundamental property of an element that indicates the number of protons present in the nucleus of an atom of that element. It is usually denoted by the symbol \( Z \). The atomic number determines the identity of the element; for example, hydrogen has an atomic number of 1 (one proton), helium has an atomic number of 2 (two protons), and carbon has an atomic number of 6 (six protons).
Australian mathematics has evolved significantly over the centuries, with various contributions coming from mathematicians in different eras. Here's a brief overview of notable Australian mathematicians by century: ### 19th Century - **John Stewart** (1834–1916): He was one of the early influential figures in Australian mathematics and made contributions to mathematics education. - **George M. Allen** (1880–1942): Known for his work on mathematical analysis and differential equations.
Cave5D refers to a virtual reality (VR) system designed for immersive experiences, particularly in the context of education, training, and visualization. It provides an environment where users can interact with 3D models and simulations, often using stereoscopic displays to create a sense of depth. Cave5D is commonly used in various fields such as architecture, engineering, science, and medicine, allowing users to explore complex datasets and environments in a more intuitive way.
Computational epidemiology is an interdisciplinary field that applies computational methods, models, and simulations to study and analyze the spread of infectious diseases and other public health issues. It combines principles from epidemiology, mathematics, computer science, and statistics to understand how diseases propagate through populations, to forecast outbreaks, and to inform public health interventions. Key aspects of computational epidemiology include: 1. **Modeling Disease Spread**: Using mathematical and computational models to simulate how diseases spread in populations over time.
Genomatix is a bioinformatics company that specializes in providing software solutions and services for the analysis of genomic data. Founded in the late 1990s, Genomatix focuses on interpreting complex biological data, particularly in the fields of genomics, transcriptomics, and epigenomics. Their tools are designed to assist researchers in understanding gene regulation, discovering biomarkers, and analyzing high-throughput sequencing data.
A Banach function algebra is a type of mathematical structure that combines the properties of a Banach space and a function algebra. To understand what this entails, we need to break down two key components: Banach spaces and function algebras. 1. **Banach Space**: A Banach space is a complete normed vector space.
Bitwise operations are operations that directly manipulate bits within binary representations of integers. These operations perform arithmetic and logical operations at the bit level, meaning they operate on the binary digits (0s and 1s) that compose the integer values.
Double Dabble is a technique commonly used in digital electronics and computer architecture, primarily for converting binary numbers (particularly binary-coded decimal, or BCD) into a format suitable for display, such as a seven-segment display. The Double Dabble algorithm involves several steps: 1. **Input Format**: It usually starts with input values represented in binary format. For BCD, each digit is encoded in four bits.
Bayesian networks, also known as belief networks or Bayes nets, are a type of graphical model that represent a set of variables and their conditional dependencies using a directed acyclic graph (DAG). In a Bayesian network: 1. **Nodes** represent random variables, which can be discrete or continuous. 2. **Directed Edges** indicate causal relationships or dependencies between the variables. An edge from node A to node B suggests that A has some influence on B.
A subtractor is a digital circuit that performs subtraction on binary numbers. It is commonly used in arithmetic logic units (ALUs) and various computing applications. The simplest form of a subtractor is a **half subtractor**, which takes two input bits and produces a difference and a borrow output. A more complex version is the **full subtractor**, which handles borrowing from previous bits, allowing it to subtract multi-bit binary numbers.
Positional games are a type of combinatorial game that involve two players competing to control positions or resources on a board or in a structured environment. These games are often defined by specific rules regarding how players can make moves and how they can claim or occupy spaces. In a typical positional game, players take turns making moves that affect the game state, with the primary objective of achieving a particular configuration or control over the board.

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.
