The transmission coefficient is a measure used in various fields of physics and engineering, particularly in wave mechanics, optics, and quantum mechanics, to describe the fraction of an incident wave (such as light, sound, or particles) that passes through a barrier or interface.
Affinity electrophoresis is a specialized technique used to separate and analyze biomolecules, usually proteins or nucleic acids, based on their specific interactions with other molecules. This method combines the principles of electrophoresis with affinity chromatography, relying on the specific binding characteristics between an analyte and a ligand. In affinity electrophoresis, the separation process is typically performed on a gel or in a solution where the desired ligand is immobilized.
Alloenzymes are variants of enzymes that have different structural forms but catalyze the same biochemical reaction. These variants arise from allelic differences in the genes that encode the enzyme, leading to slight variations in the amino acid sequence. Alloenzymes can differ in terms of their kinetic properties, stability, and regulation, but they serve the same function within the metabolic pathways of an organism.
Biliprotein is a type of protein that contains bilins as chromophores. Bilins are linear tetrapyrrole compounds that derive from the breakdown of heme, which is a component of hemoglobin and other heme-containing proteins. Biliproteins are found in various organisms, particularly in photosynthetic prokaryotes like cyanobacteria and certain algae.
China National GeneBank (CNGB) is a major biogenetic research facility located in Shenzhen, China. It was established to support the national strategy for biological resources and to promote research in genomics, biotechnology, and biodiversity. The bank serves as a repository of genetic material, including DNA, RNA, and other biological samples, and is aimed at facilitating research in various fields such as agriculture, medicine, and environmental science.
Complement component 5a (C5a) is a small but biologically active peptide that is generated during the complement activation pathway, specifically from the cleavage of complement component 5 (C5) by the enzyme C5 convertase. C5a serves as an important inflammatory mediator and plays a crucial role in the immune system by promoting various responses.
A DNA-encoded chemical library (DECL) is a powerful and innovative technology used in drug discovery and biochemistry that combines the principles of chemistry and molecular biology. It enables the rapid and efficient screening of a large number of compounds for potential biological activity. ### Key Features of DNA-Encoded Chemical Libraries: 1. **Linkage to DNA**: In a DECL, small chemical compounds are covalently linked to unique DNA tags.
DNA-templated organic synthesis is an innovative technique that uses DNA molecules as templates to facilitate the synthesis of organic compounds in a highly selective manner. This method exploits the unique properties of DNA, such as its ability to form specific base-pairing interactions and its structural stability, to guide the assembly of small organic molecules.

She has been involved in various initiatives aimed at promoting social justice, women's rights, and community development within her region. Imankozhoeva's work often focuses on empowering marginalized groups and addressing social issues in Kyrgyzstan.
"The Big Bang Theory" Season 8 is the eighth installment of the popular American sitcom created by Chuck Lorre and Bill Prady. It originally aired on CBS from September 22, 2014, to May 14, 2015. The season consists of 24 episodes and continues to follow the lives of physicists Leonard Hofstadter and Sheldon Cooper, along with their friends and fellow scientists, Penny, Howard Wolowitz, and Bernadette Rostenkowski-Wolowitz.
Jack Shaftoe is a fictional character from the historical novel series "The Baroque Cycle" by author Neal Stephenson. The first book in the series is titled "Quicksilver," followed by "The Confusion" and "The System of the World." Jack is depicted as a roguish and adventurous character, often embodying the quintessential swashbuckler archetype.
The Hofstadter Insufficiency is a concept that emerges from the world of mathematical sequences, particularly in the work of Douglas Hofstadter, who is known for his exploration of patterns and strange loops in mathematics and cognition. The term specifically refers to a property of certain recursive sequences, most famously illustrated by Hofstadter's D sequence.
"The Fish Guts Displacement" is an episode from the animated television series "The Big Bang Theory." It is the 14th episode of the show's 9th season, which originally aired on February 4, 2016. In this episode, the character Sheldon Cooper, played by Jim Parsons, struggles with feelings of jealousy and insecurity when he learns that his girlfriend, Amy Farrah Fowler, is experiencing professional success.
"The Big Bang Theory" Season 2 is the second installment of the American sitcom created by Chuck Lorre and Bill Prady. Premiering on September 22, 2008, the season continues to follow the lives of socially awkward physicists Leonard Hofstadter and Sheldon Cooper, along with their roommate and aerospace engineer Howard Wolowitz and their friend, astrophysicist Rajesh Koothrappali.
The Linear Speedup Theorem is a concept in parallel computing that describes the efficiency of a parallel algorithm in relation to the number of processors used. Specifically, it states that if a problem can be perfectly parallelized, then using \( p \) processors can speed up the execution time by a factor of \( p \).
"The Big Bang Theory" Season 5 is the fifth installment of the popular American television sitcom created by Chuck Lorre and Bill Prady. The season originally aired from September 22, 2011, to May 10, 2012, and consists of 24 episodes. In this season, viewers continue to follow the lives of physicists Sheldon Cooper and Leonard Hofstadter, along with their friends Penny, Howard Wolowitz, and Rajesh Koothrappali.
The Pestov–Ionin theorem is a result in the field of mathematical logic that deals with the preservation of certain properties in structures, particularly in the context of countable models. Although it is a specialized topic, the theorem itself is typically discussed within the framework of model theory, which studies the relationships between formal languages and their interpretations (or models).
Descartes' Rule of Signs is a mathematical theorem that provides a way to determine the number of positive and negative real roots of a polynomial function based on the signs of its coefficients. Here’s a concise breakdown of the rule: 1. **Positive Roots**: To find the number of positive real roots of a polynomial \(P(x)\), count the number of sign changes in the sequence of the coefficients of \(P(x)\).
The Gauss–Lucas theorem is a result in complex analysis and polynomial theory concerning the roots of a polynomial. Specifically, it provides insight into the relationship between the roots of a polynomial and the roots of its derivative.
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!
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.
