The Bak-Sneppen model is a theoretical framework used to study how complex systems evolve through the mechanisms of evolution, particularly focusing on the dynamics of adaptation in populations. Developed by Per Bak and Kim Sneppen in the mid-1990s, the model is especially notable for its application in the field of statistical physics, nonlinear dynamics, and evolutionary biology.
Cytoscape is an open-source software platform primarily used for visualizing complex networks and integrating these with any type of attribute data. It is widely used in bioinformatics and systems biology to analyze and visualize molecular interaction networks, biological pathways, and other types of data that can be represented as graphs.
Credit card interest is the cost of borrowing money through a credit card. It is expressed as an annual percentage rate (APR), which indicates how much interest you will pay on the outstanding balance if you do not pay it off in full by the due date. Here’s how it works: 1. **Interest Calculation**: If you carry a balance on your credit card (i.e.
Current yield is a financial metric used to assess the income generated by a fixed-income investment, such as a bond, in relation to its current market price. It provides investors with an indication of the yield they can expect to earn if they purchase the bond at its current market price, rather than at its face value.
DNA sequencing theory involves the scientific principles, methodologies, and technologies used to determine the precise order of nucleotides (adenine, thymine, cytosine, and guanine) in a DNA molecule. Understanding DNA sequencing is fundamental to genetics, molecular biology, and genomics, as it enables researchers to analyze genetic information, study evolutionary relationships, identify mutations associated with diseases, and conduct various biotechnological applications.

As of my last update in October 2023, there is no widely recognized or notable public figure named Alexandru Balaban in global news, history, literature, or other common fields. It is possible that Alexandru Balaban is a relatively private individual, a lesser-known persona, or someone who has gained prominence after my last update.
Kolmogorov equations refer primarily to a set of differential equations that describe the evolution of probabilities in stochastic processes, particularly in the contexts of Markov processes and stochastic differential equations. These equations are pivotal in the study of probability theory and were developed by the Russian mathematician Andrey Kolmogorov.
Haldane's dilemma is a concept in evolutionary biology proposed by the British geneticist J.B.S. Haldane in the early 20th century. It addresses the genetic implications of natural selection, specifically regarding the limits of adaptation in populations. The key idea behind Haldane's dilemma is that for a population to evolve beneficial traits through natural selection, there are finite limits to how quickly these traits can spread through the population based on genetic changes.
The Infinite Sites Model is a concept used in population genetics, particularly in the context of genetic mutation and variation. In this model, it is assumed that there are an infinite number of possible genetic loci (sites) that can mutate. Each locus can mutate independently, and each mutation is considered to create a new, unique genetic variant. This means that over time, as mutations accumulate, the genetic diversity in a population can increase without limit, due to the assumption of infinite sites.
Kinetic proofreading is a molecular mechanism that enhances the fidelity of biological processes, particularly in protein synthesis and DNA replication. It involves a series of kinetic steps that allow the system to discriminate between correct and incorrect substrates or interactions, thus reducing the likelihood of errors. In the context of protein synthesis, for example, kinetic proofreading refers to the way ribosomes ensure that the correct aminoacyl-tRNA is matched with the corresponding codon on the mRNA.
The Mathematical Biosciences Institute (MBI) is an interdisciplinary research institute based at The Ohio State University. It focuses on the application of mathematical techniques and methods to solve problems in the biological sciences. The institute aims to foster collaboration between mathematicians, biologists, and other scientists to advance understanding in areas such as ecology, evolutionary biology, epidemiology, and systems biology.
Biotic interchange refers to the process through which different species of organisms (flora and fauna) migrate and establish themselves in new geographical areas, often resulting in the exchange of species between ecosystems. This phenomenon can occur due to various factors such as changes in climate, continental drift, human activities, or the formation of land bridges.
The Paradox of Enrichment is a concept in ecology that describes a situation in which increasing the productivity or nutrient levels of an ecosystem can lead to a decline in biodiversity and even the stability of certain species populations. This counterintuitive phenomenon was first articulated by ecologist John T. Curtis in the context of predator-prey dynamics. In a simplified model, consider a predator-prey system where an increase in food resources (enriching the environment) allows prey populations to grow.
"Relativity" is a famous lithograph created by the Dutch artist M.C. Escher in 1953. The artwork is known for its intricate and impossible architectural constructions that challenge the viewer's perception of reality. In "Relativity," Escher depicts a world where different gravity orientations coexist, allowing figures to walk on multiple planes and surfaces that appear to defy the laws of physics. The composition includes staircases that lead nowhere and figures that interact in seemingly impossible ways.
The Binomial Options Pricing Model (BOPM) is a widely used method for valuing options, which are financial derivatives that give the holder the right (but not the obligation) to buy or sell an underlying asset at a specified price before a specified expiration date. The model was introduced by Cox, Ross, and Rubinstein in 1979 and is based on a discrete-time framework.
Vito Volterra was an Italian mathematician, born on May 3, 1860, and died on October 11, 1940. He is best known for his contributions to mathematics, particularly in the fields of integral equations, functional analysis, and mathematical biology. One of his significant contributions is the development of the Volterra integral equations, which are used to describe various physical phenomena.
The Webster equation is a mathematical model used in acoustics, particularly in the field of speech and hearing, to describe the propagation of sound waves in a tube-like structure. It is particularly applicable to the study of how sound travels through the vocal tract, which can be approximated as a series of cylindrical sections.
The Swallow's Tail is a type of kite and a mathematical shape, often referenced in different contexts. Here are a few explanations of what The Swallow's Tail might refer to: 1. **Mathematics**: In geometry, the Swallow's Tail is a type of differential surface that is shaped like the tail of a swallow. It is described by specific mathematical equations and is known for its unique curvature and properties.

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.
